    According to scientists' research, the month in which babies are born could affect them in some ways.
    Babies born in spring get sick easily. Children born under Aquarius may be less clever than those born in other seasons. They may also have shorter lives than those born in autumn  Scientists believe many of the differences can be explained by the mother's exposure to sunlight in pregnancy(怀孕).  Sunlight helps lead to the production of Vitamin D in the body. The lack of this in the first months of life may have a bad effect on mental and physical health.
    Vitamin D, called the "sunshine vitamin", is known to help regulate（调节） thousands of genes during development, according to a study of more than two million people. So Vitamin D has a good effect on health  This study showed that people born from April to June had slightly shorter lives than those born in October, November or December. Similar studies in the USA showed that people born in autumn lived about 160 days longer than those born in spring.
    Professor Russell Foster, an Oxford University neuroscientist on seasonal biology, said the conclusions were surprising and interesting. He added, "These are small effects but they are very, very clear. I am not giving voice to star signs and they are just for fun. But it is true that we are affected by our season of birth."
    小题1:A baby's season of birth doesn't affect its_______.
    A．healthB．heightC．length of lifeD．mind
    小题2:According to the passage,_______ can help people get Vitamin D.
    A. enough sleep                B. enough sunlight   
    C. fresh air                        D. suitable seasons
    小题3:Which of the following is TRUE according to the passage?
    A．People born in spring may not be in good health.
    B．Children born under Aquarius are cleverer than those born under Libra.
    C．Professor Russell Foster is interested in star signs and believes in them
    D．People born in May will live longer than those born in October.
    小题4:What does the passage mainly tell us?
    A. People can know the length of life by star sign.
    B. Women should choose to give birth to children in spring.
    C A child's season of birth has some effect on him or her.
    D. Vitamin D is very important to people's health.

    Wang Jiaming from Beijing Chenjinglun High School says he is a lucky boy. He’s happy that he’s sitting the senior high school entrance exam (中考) in 2014 instead of 2016.
    On Oct 22, Beijing Municipal Commission of Education (北京市教委) announced that, from 2016, the English scores in the senior high school entrance exam will be reduced from 120 to 100. Of the 100 points, the listening ability scores will increase to 50. Meanwhile, the points for Chinese will increase from 120 to 150.
    “The change won’t affect me. I feel so lucky because English is my strongest subject,” said Wang.
    Why such a change? It places the importance on Chinese in our study, and reduces students’ stress, said Li Yi, spokesman of the commission.
    “The change will also push us to pay attention to the practical usage (运用) of English,” said Li. “Students will be encouraged to learn to understand English menus and read English news on mobile phones.”
    There isn’t news that other cities will have the same change. But several places are making changes to English tests in the college entrance exams. For example, Shandong is considering taking out the listening part of the English exam in its college entrance exams.
    But, “being tested for less points doesn’t mean the subject can be taken lightly,” Bai Ping wrote in China Daily.
    English has long been the world’s most commonly used language. Former Chinese premier Zhu Rongji once said: “In a globalizing economy (全球经济), if you cannot communicate with foreigners, how can one be part of the world economy?”
    Wang Jiaming said he understood the change.
    “Chinese, not English, is our mother tongue (母语),” he said. “But still, I think English is both interesting and useful.”
    小题1:In the Beijing senior high school entrance exam of 2016, _____.
    A．the English scores will be cut down to 100
    B．the English listening ability scores will be lowered
    C．the points for Chinese will be reduced by 30 points
    D．the points for chemistry will increase by 20 points
    小题2: The underlined phrase “can be taken lightly” in this sentence “being tested for less points  doesn’t mean the subject can be taken lightly,” is closest in meaning to “_____________”.
    A．can be taken out
    B．can be paid less attention to
    C．can be taken a close look at
    D．can take the place of Chinese
    小题3:What is the main purpose of the change?
    A．To encourage students to learn how to order meals in English.
    B．To make students learn to read English news on mobile phones.
    C．To ask students to prepare for the college entrance exam.
    D．To make students pay more attention to learning Chinese.
    小题4:What does Bai Ping think of the reforms (改革)?
    A．They make students spend less time on English.
    B．They make it harder to get a high score.
    C．Studying English is still important for the students.
    D．English is both interesting and useful.

    We are all busy talking about and using the Internet. But how many of us know the history of the Internet?
    Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks(网络)didn't work well. If one computer in the network broke down, then the whole network stopped. So a new network system(系统) had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time 。

However, computers were still very expensive and yet Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed (开发) software (软件) that made "surfing" the Internet easier.

    The world would be a very different place if someone hadn’t invented the lift. There would be few, if any, high-rise buildings because people would refuse to climb many stairs. By the time workers reached their offices on the top floors of a tower building, it would be time to go home – if they were not too tired for the long walk down！

    The first lift that we know about was used by the Greek scientist, Archimedes, in about 230 BC. It was a simple place that could be pulled up and down with a rope. A lift like this was used much later in the 12th century by priests who lived on top of a mountain at Metereo in Greece. Because they were afraid of killers, the priests had not built any stairs up the mountain. The only way up was by lift, which priests worked from the top of the mountain.
    A few hundred years later, a Frenchman, Villayer, invented a ‘flying chair’ which used a rope and a place. A number of rich people had these ‘flying chairs’ built in their homes, including Queen Anne of England in Windsor Castle and Louis XVI of France at Versailles. Unluckily, Louis’ daughter was badly hurt when using one of the chairs, and Villayer ran away, afraid that he would be punished.
    The main problem for lift engineers was that either humans or animals were needed to pull the ropes. This problem was not worked out until the discovery of steam power. But even steam powered lifts were not always safe because they also used ropes which sometimes broke. If the rope broke - which it sometimes did - the lift fell to the ground and people in it were killed or hurt. This problem worked out in 1854 when an American, Elisha Otis, invented something which stopped the lift from falling if the rope broke. At first Otis lifts were used only in factories, then in 1857 he built one in a large New York store. Now lifts use electric power and are completely safe. They also travel very quickly. Some lifts travel faster than 60 kilometers an hour.
    小题1:The writer thinks that lifts are important today because __________.
    A．people like playing on them
    B．they are the best way of using steam power
    C．we need them for tall buildings
    D．workers are lazy
    小题2:The 12th century priests had a simple lift instead of stairs because ___________.
    A．they thought the stairs were broken
    B．they liked having stairs and a lift
    C．the lived at the bottom of a mountain
    D．they were afraid of killers
    小题3:Villayer thought he would be punished because ____________.
    A．poor people could not afford his ‘flying chair
    B．someone was hurt in one of his ‘flying chairs’
    C．his ‘flying chair’ did not work at all
    D．he ran away with Louis XVI’s daughter
    小题4:Steam power meant that ________  .
    A．they did not need a living thing to pull the ropes
    B．Elisha Otis could invent a lift that would not fall
    C．the rope always broke
    D．they could use lifts in factories

    You’ve probably heard of working dogs that help police officers, or horses that help farmers. Did you know that carrier pigeons（信鸽）can be trained to help people too? Here are some examples.
    Mailman
    Carrier pigeons can be trained to carry messages to people. The note is placed into a small can. The can is tied to the pigeon’s leg. Then the pigeon flies off with the note.
    Lifeguard
    From high up in the sky, specially trained pigeons can find orange life jackets in the ocean. Sometimes it is difficult for humans to find people lost at sea, especially when the weather is bad. However, pigeons can fly quickly over a large area of water to look for people.
    Spy
    Many years ago, carrier pigeons were used to help our country during wars (战争). “Spy pigeons” had small cameras that were tied to their feet. As a pigeon flew over enemy (敌人)land, the camera took photos of the land below. This would allow our soldiers to see where the enemies were and what they were doing.

    小题1:Which part of the carrier pigeon is the can tied to?

    A．A pigeon could predict what the weather would be like.
    B．A pigeon was tied with a small camera around its leg.
    C．A pigeon could help us to know the number of the enemy.
    D．A pigeon carried the camera to take photos of the enemy land.
    小题4:What kind of jobs are mentioned for a carrier pigeon?
    A．A mailman, a lifeguard and a spy.
    B．A trainer, a spy and a police officer.
    C．A soldier, a police officer and a mailman.
    D．A farmer, a weather reporter and a lifeguard.
    小题5:What is the purpose of writing this article?
    A．To make readers like pigeons more.
    B．To teach readers about the lives of wild pigeons.
    C．To tell readers about real jobs held by carrier pigeons.
