About 35 percent of British adults sleep with teddy bears. Many more share a bed with a partner or spouse. Others still co - sleep, alongside children in a family bed.
But lying with your iPad? A recent survey by marketing agency Rosette found that 68 percent of tablet owners use the device in the bedroom, more than in any other location. The living room took a close second place, at 63 percent, reports AdAge. com, and only 45 percent of respondents said they use their tablets on the go.
But bringing devices into the bedroom is a bad idea, if quality rest is your goal. One of the most important factors of sleepiness is darkness, which signals to the brain that it’s time to start speeding up production of the sleep - inducing hormone melatonin. But as the New York Times points out, in our modern world, we are exposed to light long after the sun sets. While any type of light can disturb your sleep, the blue wavelength light given off by cell phones, laptops, tablets and other gadgets is particularly troublesome. Research shows that this blue light causes alertness so decisively that it can actually be used to fight tiredness.
According to the National Sleep Foundation, 95 percent of Americans use some device, whether it’s a TV, laptop, cell phone or other products, within an hour of killing time. “Artificial light exposure between dusk and the time we go to bed at night push our sleeping sense to a later hour - making it more difficult to fall asleep,” said Charles Czeisler, Ph. D. , M. D. , chief of the division of sleep medicine at Brigham and Women’s Hospital in Boston.
Instead, experts recommend turning off all devices an hour before bedtime and finding another method for relaxation, like reading a book, taking a warm bath or performing a series of calming yoga poses. It’s also a good idea to exercise and lay off the caffeine several hours before bedtime.
小题1: According to a recent survey, most tablet owners use their iPad ________.

A．in the living room	B．in the bedroom
C．in the office	D．on the move

小题2: What can we know from this passage?

A．The light from cell phones is harmful

B．Modern people have trouble falling asleep

C．Darkness can create a good sleeping environment

D．Blue light can prevent sleepiness decreasing

小题3:If we often play with a laptop just before sleep, we’ll be more likely to ________.

A．dream of it

B．stay awake

C．feel sleepy

D．become tired

小题1:B
小题2:C
小题3:B

试题分析：文章主要介绍了平板电脑在全球走红的趋势。最近由Rosetta运销商发起的一项研究显示，有68%的平板电脑用户会青睐在卧室玩自己的宝贝。
小题1:B 细节题。根据文章第二段的A recent survey by marketing agency Rosette found that 68 percent of tablet owners use the device in the bedroom, more than in any other location可知平板电脑用户更倾向于在卧室使用，所以选B
小题2:C 细节题。根据文章第三段One of the most important factors of sleepiness is darkness, which signals to the brain that it’s time to start speeding up production of the sleep可知黑暗能促进睡眠，所以选C
小题3:B 推断题。根据文中给出的信息Artificial light exposure between dusk and the time we go to bed at night push our sleeping sense to a later hour - making it more difficult to fall asleep可知如果睡前玩平板电脑很可能导致失眠。所以选B

Some students get so nervous before a test; they do poorly even if they know the material. Sian Beilock has studied these highly anxious test-takers.
Sian Beilock: “They start worrying about the consequences. They might even start worrying about whether this exam is going to prevent them from getting into the college they want. And when we worry，it actually uses up attention and memory resources. I talk about it as your cognitive horsepower that you could otherwise be using to focus on the exam.”
Professor Beilock and another researcher，Gerardo Ramirez，have developed a possible solution. Just before an exam，highly anxious test-takers spend ten minutes writing about their worries about the test.
Sian Beilock: “What we think happens is when students put it down on paper，they think about the worst that could happen and they reappraise the situation. They might realize it’s not as bad as they might think it was before and，in essence(本质上)，it prevents these thoughts from popping up when they’re actually taking a test.”
The researchers tested the idea on a group of twenty anxious college students. They gave them two short math tests. After the first one, they asked the students to either sit quietly or write about their feelings about the upcoming second test.
The researchers added to the pressure. They told the students that those who did well on the second test would get money. They also told them that their performance would affect other students as part of a team effort.
Professor Beilock says those who sat quietly scored an average of twelve percent worse on the second test. But the students who had written about their fears improved their performance by an average of five percent.
Next, the researchers used younger students in a biology class. They told them before final exams either to write about their feelings or to think about things unrelated to the test.
Prefessor Beilock says highly anxious students who did the writing got an average grade of B+，compared to a B－ for those who did not.
Sian Beilock: “What we showed is that for students who are highly test-anxious，who’d done our writing intervention(排解)，all of a sudden there was no relationship between test anxiety and performance. Those students most likely to worry were performing just as well as their classmates who don’t normally get nervous in these testing situations.”
But what if students do not have a chance to write about their fears immediately before an exam or presentation? Professor Beilock says students can try it themselves at home or in the library and still improve their performance.
小题1:Which of the following is TRUE?

A．The result in the math test agrees with that in the biology test.

B．In the first math test, students who sat quietly performed better.

C．In the second math test, students who wrote about their feelings did worse.

D．Some college students are highly anxious test-takers while others are not in the tests.

小题2:What may happen if students have the problem of test anxiety?

A．Test anxiety is sure to cause students to fail the test.

B．Test anxiety can improve students’ performance to some degree.

C．Students’ attention and memory resources run out when worried.

D．Students may not be admitted into their favorite college if worried

小题3:The result of the research suggests that ________．

A．proper amount of burden may turn out to be a good thing

B．facing the fears bravely may help one to achieve more

C．avoiding facing the problem may contribute to relaxation

D．taking no action before difficulty may result in success

小题4:What is the main idea of the passage?

A．It is important for students to overcome test anxiety.

B．Anxious students overcome test anxiety by writing down fears.

C．It is a common practice for students being worried before a test.

D．Being worried before tests does harm to students’ performance.

Astronomers have captured(捕获) the first direct image of a planet being born.
Adam Kraus, of the University of Hawaii’s Institute for Astronomy, said the planet is being formed out of dust and gas circling a 2-million-yea-old star about 450 light years from Earth.
The planet itself, based on scientific models of how planets form, is believed to have started taking shape about 50,000 to 100,000 years ago.
Called LkCa 15b, it’s the youngest planet ever observed. The previous record holder was about five times older.
Kraus and his colleague, Michael Ireland from Macquarie University and the Australian Astronomical Observatory, used Keck telescopes on Mauna Kea(a volcano on the island of Hawaii, US) to find the planet. Kraus presented the discovery Wednesday at NASA’s Goddard Space Flight Center in Maryland.
Observing planets while they’re forming can help scientists answer questions like weather planets form early in the life of a star or later, and whether they form relatively close to stars or father away.
Planets can change orbits(轨道) after forming, so it’s difficult to answer such questions by studying older planets.
“These very basic questions of when and where are best answered when you can actually see the planet forming, as the process is happening right now,” Kraus said.
Scientists hadn’t been able to see such young planets before because the stars they’re circling around outshine(光亮强过) them. Kraus and Ireland used two techniques to overcome this problem.
One method, which is also used by other astronomers, was to change the shape of the telescope mirrors to remove light distortion(扭曲) created by the Earth’s atmosphere. The other method they used, which was unique, was to put masks with several holes over most of the telescope mirrors. The combination of these techniques allowed the astronomers to obtain high-quality images that let them see the planet next to the bright star.
The star LkCa 15—the planet is named after its star—was the team’s second target. They immediately knew they were seeing something new, so they plan to gather more data on the star.
小题1:The research on younger planets helps scientists _____________.

A．study why planets change orbits after forming

B．understand how planets move around their stars

C．answer questions about the age of stars and planets

D．know the relationship between planets and their stars

小题2:Why are young planets like LkCa 15b hard to discover?

A．Their stars are brighter than them..	B．They are very far from the earth.
C．They are generally too small.	D．They rarely form.

小题3:According to the text, Kraus and Ireland _____________.

A．have been working in the same university

B．observed the planet on a volcano in Hawaii

C．used two new methods in the observation

D．cut holes in the mirrors when observing

小题4:Which of the following would be the best title for the text?

A．Youngest planet seen as it’s forming.

B．Planet 450 light years away discovered.

C．World’s first direct image of a planet taken.

D．New technique helps discover young planets.

It seems that many college graduates are unsure of what to do with their lives, so they jump back into the college scene by default(违约). But graduate school is costly, time consuming and requires a lot of in-depth study, and also parents will lay down more money and banks will supply more student loans.
However, there are some students who should be pursuing graduate degrees. Teachers, lawyers, doctors, professors and ministers are a few examples of those who will benefit from class work past a bachelor’s degree. Their professions call for additional courses and more specialization and therefore higher education is a must. Still, all students in general should not adopt the idea that graduate school is necessary for individuals who want to make more money. Working hard right after college can lead to promotions in the future. It seems that it does more good to network or internship（实习）with professionals while pursing a bachelor’s degree than it does to complete a master’s and distant oneself from the world of work.
If a student graduates with a four-year degree and immediately enters the work force , he will most likely start an entry-level pay. In a couple of years this employee will gain seniority and experience, therefore increasing their chance for pay rise. He will learn the information at his job-site that he did not learn in school. His bachelor’s degree loan can be immediately chipped away ,and his maturity level can increase as real work related responsibilities set in. But, if the student pursues a master’s degree, he may be able to demand more pay initially when he finally goes job hunting, but years of serious money making as well as work experience will already be lost.
Students should not shy from the workforce just because uncertainty follows graduation. Those who pursue a graduate degree just because they do not want to leave school and because they view the “real world” as scary should think again. Using graduate studies as a hiding place from the full-time job is a waste of time.
小题1:College graduates who go to work can _____ than those who pursue graduate degrees.

A．make more money in the future	B．acquire more experience
C．get a better job	D．become more responsible

小题2:The underlined words “chipped away” can most possibly be replaced by_______.

A．given out

B．set down

C．thrown away

D．paid off

小题3:What would be the best title for the passage?

A．College graduates shouldn’t pursue graduate degrees

B．College graduates should think twice

C．How can college graduates make more money?

D．Students use graduate school to avoid reality

It’s common for parents to feel emotional when the moment comes for their child to leave home and go to university. Even parents who don’t speak about the event are likely to feel a sense of sadness because it’s the end of an era where you and your family were at the centre of your child’s world. As a parent you’ll probably continue to support your child in different ways, but the main job of raising your child is over. It’s a huge change for everyone involved.
There are a few things that you can do to make the transition easier. Plan carefully for your child’s departure and think about how you can help. Many parents take their child to university for the first time. If you decide to do that, be ready to feel a real wrench when the time comes to say goodbye. Your child will probably be as nervous as you are about the moment when you finally say goodbye – but that might not show!
Be positive and cheerful about the choice your child has made to continue studying, and plan to leave once you’ve unpacked the car and looked around your child’s new living accommodations. If you can, save your tears for the car – you’ll make things easier on your child and yourself.
The more you’ve invested in being a parent, the more you’ll feel a sense of loss, so the sadness you feel now is a sign that you’ve been a good mom or dad. Remind yourself that parenting is all about raising an independent and confident child who functions well without you. If your child quickly settles and starts enjoying himself, you should congratulate yourself.
It’s also only fair to allow yourself some time to grieve. Don’t expect to pick yourself up and move on straight away. But you may decide to find a hobby or sport to fill your extra time. Perhaps you’ve always wanted to learn a new language, go to yoga classes or take up swimming. You may decide to spend more time with family and close friends, who are likely to be feeling the absence of your child as well.
Agree on the best approach to staying in touch before your child leaves, and stick to your agreement. Try not to panic if your child doesn’t respond immediately – remember, they’re starting a new and busy life.
小题1:The underlined word “wrench” in Paragraph 2 means a feeling of ________.

A．sorrow

B．regret

C．anger

D．love

小题2:What does good parenting consist of?

A．Supporting your child in different ways all the time.

B．Congratulating yourself when your child goes to college.

C．Preparing your child to stand on their own feet in the future.

D．Investing as much as possible in the growth of your child.

小题3:What’s NOT advised as the way to recover from your child’s departure?

A．Developing a new hobby or sport

B．Learning a new language.

C．Spending more time with close friends

D．Staying in touch with your child.

小题4:What would be an appropriate title for the whole passage?

A．Staying in Touch with Your Child

B．Preparing to Say Goodbye to Your Child

C．Dealing with Your Child Leaving Home for University

Today, there are many chances for those who wish to continue their education. However, nearly all require some break in one’s career in order to attend school full time. 　　
Part-time education, that is, attending school at night or for one weekend a month, tends to drag the process out over time and puts the completion of a degree program out of reach of many people. Additionally, such programs require a fixed time commitment which can also impact negatively on one’s career and family time.
Of the many approaches to teaching and learning, however, perhaps the most flexible (灵活的) is that called distance learning. Distance learning is an educational method which allows the students the flexibility to study at his or her own pace to achieve the academic goals which are so necessary in today’s world. The time required to study may be set aside at the student’s convenience. Additionally, the student may enroll in distance learning courses from actually any place in the world, while continuing to pursue their chosen career. Individual assistance may be available via regular airmail, telephone, fax machine, teleconferencing and over the Internet.
Good distance learning programs are characterized by the inclusion of a subject evaluation tool with every subject, so a student doesn’t need to travel away from home to take a test. Another characteristic of a good distance learning program is the equivalence (等同) of the distance learning course with the same subject materials as those students taking the course on the home campus. The resultant diploma or degree should also be the same whether distance learning or on-campus study is employed. The individuality of the professor/student relationship is another characteristic of a good distance learning program. In the final analysis, a good distance learning program has a place not only for the individual student but also the company or business that wants to work in partnership with their employees for the educational benefit, professional development, and business growth of the organization. Supporting distance learning programs for their employees gives the business the advantage of retaining (留住) career-minded people while contributing to their personal and professional growth through education. 　　
小题1:According to the passage, which of the following is NOT a disadvantage of part time education?

A．It requires some break in one’s career. 　　

B．It tends to last too long for many people to complete a degree program.　　

C．It affects one’s career.　　

D．It gives the student less time to share with the family.

小题2: Which of the following is NOT an advantage of distance learning? 　

A．The student may choose his or her own pace.　

B．The student may study at his or her convenience.　　

C．They can pursue their chosen career while studying.

What makes a person a scientist？Does he have ways or tools of learning that are different from those of others？The answer is “no”. It isn’t the tools a scientist uses but how he uses these tools which make him a scientist. You will probably agree that knowing how to use a power is important to a carpenter(木匠).You will probably agree，too，that knowing how to investigate(调查)，how to discover information，is important to everyone. The scientist，however，goes one step further；he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.?
The scientist’s knowledge must be exact. There’s no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one set of conditions at one time must work under the same conditions at other times. If the conditions are different，any changes the scientist observes in a demonstration(实证)must be explained by the changes in the conditions. This is one reason why investigations are important in science. Albert Einstein，who developed the Theory of Relativity，arrived at this theory through mathematics. The accuracy(正确性)of his mathematics was later tested through investigation. Einstein’s ideas were proved to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations(计算)that may test his investigations.
小题1:What makes a scientist according to the passage？

A．The tools he uses.	B．His ways of learning.
C．The way he uses his tools.	D．The various tools he uses.

小题2:“...knowing how to investigate，how to discover information，is important to everyone.” The writer says this to show_______.

A．the importance of information

B．the difference between scientists and ordinary people

C．the importance of thinking

D．the difference between carpenters and ordinary people

小题3: A sound（合理的） scientific theory should be one that_______.

A．works under one set of conditions at one time and also works under the same conditions at other times

B．doesn’t allow any change even under different conditions

C．leave no room for improvement.

D．can be used for many purposes

小题4:What is the main idea of the passage？

A．Scientists are different from ordinary people.

B．The Theory of Relativity?.

C．Exactness is the core(核心)of science.

D．Exactness and way of using tools are the keys to making of a scientist.

At the beginning of this century, medical scientists made an interesting discovery; we are built not just of flesh and blood but also of time. They were        to show that we all have “a body clock”         us, which controls the        and fall of our body energies,        us different from one day to the next.
The        of “a body clock” should not be too        since the lives of most living things are controlled        the 24 hour night-and-day cycle. We feel        and fall asleep at night and become        and energetic during the day. If the 24 hour-cycle is        , most people experience unpleasant        . For example, people who are not        to working at night can find that        of sleep causes them to        badly at work.
