A

A big bowl of milk can be a great way to start the day. Many snack bars contain nutrients that help our bodies stay strong and healthy. But some of these foods are packed with too many vitamins and minerals. According to a new study by the Environmental Working Group (EWG), this extra fortification may be more harmful than helpful.

Of the tested snack bars, 27 have more than 50% of the recommended amounts of vitamin A, niacin and zinc. Nutrition facts listed on packages are based on recommended daily values for adults, who are physically larger and require more vitamins and minerals. So when kids eat these cereals (麦片) and snack bars, they are getting more nutrients than they need.

Vitamin A, niacin (烟酸) and zinc (锌) are best in fresh and unprocessed foods that are in their natural state. Vitamin A helps you see at night. It occurs naturally in eggs, meat and carrots. Niacin is a vitamin that helps our bodies make energy. It is found in foods like fish, seeds, and peanuts, as well as in whole grains like wheat and brown rice. Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans and nuts.

Children typically eat more than one serving of cereal or snack bars a day, in addition to taking vitamin supplements. Eating large amounts of these nutrients can be dangerous to kids’ health. Too much vitamin A can cause liver damage, and high levels of zinc can destroy the body’s natural immunity, or power to fight infection.

The EWG authors are calling for the FDA to make changes to its guidelines for nutrient intake and revise its daily values to match kids’ diets.

【1】 What can we infer from the second paragraph ?.

A. most kids are lack of nutrition.

B. kids need less nutrients than adults.

C. the cereals are full of all kinds of nutrients.

D. the snack bars don’t have enough nutrients .

【2】If you want to avoid infection, what food should you eat more?

A. Meat and nuts. B. Fish and rice.

C. Eggs and carrots. D. Beans and fruits.

【3】The fourth paragraph is mainly to tell us that__________.

A. children like eating fast food

B. vitamins can damage immunity

C. too many nutrients affect health

D. children should refuse to eat cereal

【4】What would be the best title for the text?

A. Nutrients and kids’ health.

B. Students’ diet at school.

C. Kids’ three main nutrients.

D. The importance of nutrients.

【答案】

【1】B

【2】A

【3】C

【4】A

【解析】本文是议论文。文章通过对孩子饮食现状的研究和调查可知,过量营养对孩子们有很大的坏处,专家认为,这种情况需要得到有效的控制。

【1】 B 推理判断题。该段介绍了研究的情况,特别是联系第四句及最后一句So when kids eat these cereals and snack bars, they are getting more nutrients than they need,可知,孩子需要的营养比成年人要少,故正确答案为B。

【2】A 推理判断题。文章第三段介绍了营养对健康的好处,根据其中Zinc helps our bodies fight off infection. It is found in many foods, including wheat-based products, meats, beans, and nuts可知,要避免感染需要吃富含锌的食物,包括肉和坚果。

【3】 C 推理判断题。本段主要介绍了过量营养的坏处,这样C项符合题意。根据该段第二句中的Eating large amounts of these nutrients可知,孩子们也许喜欢吃这些东西,但这不是作者想要告诉读者的段落思想,故A项错误。

【4】 A 主旨大意题。本文主要介绍了营养和孩子们的健康的关系,侧重于过量营养对健康的负面的作用,据此可以推知,A项为本文最佳标题。联系主题思想,本文不是介绍三大营养,所以C项不对。

阅读下列短文,从每题所给的四个选项(A、B、C和D)中选出最佳选项。

Students from Florida International University in Miami walked on water Thursday for a class assignment. To do it, they wore aquatic (水上的) shoes they designed and created.

Alex Quinones was the first to make it to the other side of a 175-foot lake on campus in record time—just over a minute. Quinones, who wore big boat-like shoes, also won last year and will receive $500.

Students had to wear the aquatic shoes and make it across the lake in order to earn an “A” on the assignment for a special course. “Its traditional in a school of architecture to do boats out of cardboard (硬纸板) for a boat race. I thought our students were a little bit more special than that, Canaves said. “We decided to do the walk on water event to take it to the next level.”

A total of 79 students competed in the race this year in 41 teams. Only 10 teams failed to cross the lake. Others who fell got back up and made it to the end. The race is open to all students and anyone in the neighborhood. The youngest person to ever took part was a 9-year-old girl who competed in place of her mother, while the oldest was a 67-year-old woman. A large crowd on campus joined Canaves as he cheered on the racers. He shouted encouraging words, but also laughed as some unsteadily made their way to the end.

“A part of this is for them to have more understanding of designing and make it work better, he said. It is also a lesson in life for the students.

“Anything, including walking on water, is possible, if you do the research, test it and go through the design process seriously.

【1】What can we learn about Alex Quinones?

A. He finished the race in less than a minute.

B. He won the race with the help of 2 boats.

C. He failed the race last year.

D. He set a new record this year.

2For what purpose did the students join in the race?

A. To go across the lake to school.

B. To test their balance on the water.

C. To earn a good grade for a course.

D. To win the prize money of $500.

3What can we learn according to the fourth paragraph?

A. More than 20 teams failed to cross the lake.

B. The students who fell into the water had to quit.

C. The students kept silent when the other racers competed.

D. The youngest competitor competed instead of her mother.

4According to Canaves, this race can help the students ________.

A. understand designing better

B. achieve almost everything

As the saying goes, chance favored the prepared mind. I learned this from one of my experience. I was not chosen as member of the volleyball team of our school. Because of this, I decided to give up play volleyball. Luckily, my best friend stopped me but pointed out that it was my laziness and poor preparation which led to my failure. After that, I practiced playing volleyball on every day. When another tryout arrived, I was full prepared and tried my best. As a result, I was selected and became an important player on our school team.

From this, I am firmly convincing that we are able to seize a chance as long as I get well prepared.

Friendships are very important to teenagers. Friendships provide teenagers with chances to develop social skills. Teenagers can learn how to end a fight and still remain friends.

阅读下列短文,从每题所给的四个选项 (A 、B 、C D )中,选出最佳选项,并在题卡上将该项涂黑。

The pillage (掠夺) and destruction of ancient shipwrecks and sunken archaeological sites by treasure hunters seeking gold and other valuables may be illegal under the terms of an international treaty under discussion by UNESCOs 188 Member States.

"Protecting our underwater heritage is extremely important and increasingly urgent as no site or shipwreck is now out of bounds for treasure hunters. New technologies have made deep-water wrecks easily accessible and these technologies are getting cheaper," warns Lyndel Prott.

According to estimates by commercial salvors (寻宝者), there are some three million undiscovered shipwrecks scattered across the worlds oceans. Even the figures for the known wrecks are impressive. The Northern Shipwrecks Database for example contains 65,000 ship loss records for North America alone from 1500 AD to the present. The Dictionary of Disasters at Sea by Charles Hocking (1969) lists 12,542 sailing ships and war vessels lost between 1824 and 1962.

Then there are sunken cities such as the trading town and pirate stronghold(海盗堡垒) of Port Royal in Jamaica, which disappeared beneath the waves after an earthquake in 1692. Or the remnants of ancient civilisations, such as the Lighthouse of Alexandria in Egypt, and the Neolithic villages being discovered under the Black Sea, which some believe could help explain Noah’s great flood.

These treasures of cultural heritage are under serious threat. Technology now allows extraordinary access to the ocean depths for deermined and well-financed treasure hunters. And the potential rewards are huge. In 1985, American salvor Mel Fisher discovered the wreck of the Seora de Atocha, a Spanish ship that sank off the Florida Keys in 1622 with her cargo of gold, silver and jewellery worth an estimated US $400 million.

An archaeologist can spend ten years or more studying a ship, conserving its objects and publishing its findings. We gain an enormous amount of information and knowledge from this work. With treasure hunters, all of this is lost. This is tragic, for humanity as a whole.

【1】Why is it important and urgent to protect our underwater heritage?

A. Underwater heritage is easily accessible to treasure hunters.

B. Underwater heritage is out of reach of archaeologists.

C. New technology makes protection of underwater heritage easier.

D. There is no law to protect underwater heritage.

【2】What is the third paragraph mainly about?

A. Shipwrecks discovered by commercial salvors.

B. The main cause of shipwrecks.

C. The history of sunken ships.

D. The figures of shipwrecks around the world.

【3】What happened to Port Royal in 1692?

A. It was washed away by flood.

B. It was beneath the waves after an earthquake.

C. It was discovered under the Black Sea.

D. It was rebuilt by Noah.

【4】Why is Mel Fisher mentioned in the fifth paragraph?

A. He risked his life in treasure hunting.

B. He was one of the most successful commercial salvors.

C. He made a great discovery of shipwrecks.

D. He had no trouble in finding a shipwreck.
