【题目】根据短文内容, 从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Most drinks stating that they are fruit flavored contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
"Shoppers need to check the labels before buying drinks, though sometimes the actual content can be nonexistent," said Food Commission spokesperson Ian Tokelove. "Food production is highly competitive. It will increase profits, and consumers won't always realize they are being tricked."
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberryflavored products sold in stores. Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
Let's take jam as an example. Some strawberryflavored jam was labeled as containing no artificial color1 s, flavors, or sweeteners, but it contained ly no strawberries at all.
Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. "Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. Unfortunately, it is also legal and widespread," Tokelove said. "It's time to take measures to protect the consumers' rights."
A. They found that about 60 percent of them didn't contain any fruit at all.
B. Even products advertised as more natural often contained no fruit.
C. The products which contain real fruit are popular with people.
D. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.
E. It is important and necessary to demand a small amount of flavoring in the products.
F. If companies can cut their costs by using flavoring, they are likely to do so.
G. The Food Commission suggested all flavors used in a product should be listed on the packaging.

【题目】根据短文理解,选择正确答案。
It is reported that conservation groups in North America have been arguing about the benefits and dangers of wolves. Some groups believe wolves should be killed. Other people believe wolves must be protected so that they will not disappear from the wilderness(荒野).
For Killing Wolves
In Alaska,the wolf almost disappeared a few years ago,because hunters were killing hundreds of them for sport. However, 1aws were established to protect the wolves from sportsmen and people who catch the animals for their fur.So the wolf population has greatly increased. Now there are so many wolves that they are destroying their own food supply.
A wolf naturally eats animals in the deer family. People in the wilderness also hunt deer for food. Many of the animals have been destroyed by the very cold winters recently and by changes in the wilderness plant life.When the deer can't find enough food,they die.
If the wolves continue to kill large numbers of deer, their prey(猎物) will disappear some day. And the wolves will, too. So we must change the cycle of life in the wilderness to balance the ecology. If we killed more wolves, we would save them and their prey from dying out. We'd also save some farm animals.
In another northern state, wolves attack cows and chickens for food. Farmers want the government to send biologists to study the problem. They believe it necessary to kill wolves in some areas and to protect them in places where there is a small wolf population.
Against Killing Wolves
If you had lived long ago,you would have heard many different stories about the dangerous wolf.According to most stories,hungry wolves often kill people for food.Even today,the stories of the “big bad wolf” will not disappear.
But the fact is wolves are afraid of people, and they seldom travel in areas where there is a human smell.When wolves eat other animals,they usually kill the very young, or the sick and injured. The strongest survive. No kind of animal would have survived through the centuries if the weak members had lived. And has always been a law of nature.
Although some people say it is good sense to kill wolves,we say it is nonsense! Researchers have found wolves and their prey living in balance.The wolves keep the deer population from becoming too large, and that keeps a balance in the wilderness plant life.
The real problem is that the areas where wolves can live are being used by people. Even if wilderness land is not used directly for human needs, the wolves can't always find enough food. So they travel to the nearest source, which is often a farm. Then there is danger. The “big bad wolf” has arrived! And everyone knows what happens next.
(1)According to the passage, some people in North America favor killing wolves for all the following reasons EXCET that ________.
A.there are too many wolves
B.they kill large numbers deer
C.they attack cows and chickens for food
D.they destroy the wilderness plant life
(2)According to those against killing wolves, when wolves eat other animals, ________.
A.they never eat strong and healthy ones
B.they always go against the law of nature
C.they might help this kind of animals survive in nature
D.they disturb the ecological balance in the wilderness
(3)The last sentence “And everyone knows what happens next” implies that in such cases ________.
A.farm animals will be in danger and have to be shipped away
B.wolves will kill people and people will in turn kill them
C.wolves wilI find enough food sources on famls
D.people will leave the areas where wolves can live

Dear Sally,
Now I'd like to tell you something about my part-time job this summer vacation, of which I worked like a guide in a travel agency.The work was interesting but tired. I think it was helpful to work this holiday. It was the first time that I have earned money on my own.I've come to understand how hard my parents work to support for the family. I used to keep on ask them for money, but now I'll never waste money and learn to share worry with my parent. I've learnt how to get along well with others.
What's worse, I've gained some working and social experience and I have learnt something can' t be learnt from textbooks. All these will be good for my future. In a word, I had the wonderful and valuable summer vacation.
Yours,
Li Bing

More than four decades ago British scientist Robert Edwards first witnessed the miracle of human life growing inside a test tube at his Cambridge lab. Since that ground-breaking moment, more than four million babies have been born through IVF and in 2010 his great contribution to science was finally recognized as he was awarded the Nobel Prize for medicine.
The prize for Dr. Edwards, who was given a Daily Mirror Pride of Britain Award in 2008, includes a 900,000 check. The Nobel Assembly described IVF as a “milestone in modern medicine”.
With the help of fellow scientist Patrick Steptoe, the Manchester-born physiologist developed IVF — leading to the birth of the world's first test tube baby. Dr. Steptoe died 10 years later but their work has transformed fertility treatment and given hope to millions of couples.
It was a scientific breakthrough that transformed the lives of millions of couples. They said: “His achievements have made it possible to treat infertility, a disease which makes human unable to have a baby. This condition has been afflicting a large percentage of mankind including more than 10% of all couples worldwide.”
Louise Brown, the world's first test tube baby, made international headlines when she was born in Oldham, Gtr Manchester, in 1978 to parents Lesley and John who had been fruitlessly trying for a baby since 1969.
Ivf-in-vitro fertilization is the process whereby egg cells are fertilized outside the body before being implanted in the womb. After a cycle of IVF, the probability of a couple with infertility problems having a baby is one in five—the same as healthy couples who conceive naturally.
Professor Edwards, who has five daughters and 11 grandchildren, began his research at Cambridge University in 1963, after receiving his PhD in 1955. He once said: “The most important thing in life is having a child. Nothing is more special than a child.” With the help of fellow scientist Patrick Steptoe, Prof. Edwards founded the Bourn Hall clinic in Cambridge shire, which now treats more than 900 women a year. Each year, more than 30,000 women in Britain now undergo IVF and 11,000 babies are born as a result of the treatment.
But his work attracted widespread criticism from some scientists and the Catholic Church who said it was “unethical and immoral”.
Martin Johnson, professor of reproductive sciences at the University of Cambridge, said the award was “long overdue”. He said: “We couldn't understand why the Nobel has come so late but he is delighted — this is the cherry on the cake for him.”
Professor Edwards was too ill to give interviews but a statement released by his family said he was “thrilled and delighted”.
(1)What is Robert Edwards' contribution to science?
A.Enabling millions of couples to live a better life.
B.Helping couples with infertility to have tube babies.
C.Seeing the wonder of the first tube baby growing
D.Challenging a disease which stops human having a baby.
(2)Why did Professor Edwards begin his research on tube baby?
A.Because a special child did make a difference to an ordinary family.
B.Because the birthrate around the world was unexpectedly low then.
C.Because he thought it of great significance to have a child in life.
D.Because his fellow scientist wanted to give hope to the unlucky couples.
(3)It can be inferred from Paragraph 8 and Paragraph 9 that ________.
A.Professor Edwards deserved the prize for his breakthrough
B.different opinions were voiced on Professor Edwards' finding
C.some people envied Professor Edwards for his being awarded
D.the prize was late because the finding was first considered immoral
(4)What might be the best title for the passage?
A.Life Stories of Robert Edwards
B.Preparations for Having a Baby
C.Nobel Prize for IVF Expert Edwards
D.Treatment of Infertility in a Lab

【题目】根据短文理解,选择正确答案。
Why do human beings still risk their lives under ground and doing one of the dirtiest and most dangerous jobs in the world? It is an increasingly urgent question, given the recent mining accidents in Sago, W. Va and Huntington, Utah. A small group of engineers and robotics experts look forward to a day in the not-too-distant future when robots and other technology do most of the dangerous mining work.
Robotic technology, in particular, holds much promise, McAteer says, especially when it comes to mapping mines and rescuing trapped miners — the special operations of the mining industry.
One of the first mining robots was developed five years ago at Carnegie Mellon University's Robotics Institute. It was called Groundhog. It used lasers(激光器) to “see” in dark tunnels and map abandoned mines—some of the most dangerous work in the business.
The latest design is called Cave Crawler. It's a bit smaller than Groundhog, and even more advanced. It can take photos and videos and has more sensors that can detect the presence of dangerous gases. Incredibly, the robot has a real sense of logic. If it comes across an obstacle it gets momentarily confused. It has to think about what to do and where to go next. Sometimes it throws a fit just like a real person.
The greatest problem, though, is cost. The money of the earliest research project was provided by the government, but that money had dried up, and it's not clear where future money will come from. Partly for that reason, and partly because of advances in safety, mining is not nearly as dangerous as it was in the past. Since 1990, fatalities(致命性) have declined by 67% and injuries by 51% , according to the National Mining Association.
Some experts predict that robots in mines will serve much of the same function that they do in the automotive industry. The robots do the most boring and dangerous jobs,but won't get rid of the need for human workers.
(1)The latest robot is more advanced than Groundhog, mainly because ________.
A.it can map abandoned mines
B.it has a real sense of logic
C.it can see in the dark tunnels
D.it's smaller than Groundhog
(2)The underlined phrase “throws a fit” in paragraph 4 probably means“________”.
A.gets sick
B.gets angry
C.becomes hungry
D.becomes cheerful
(3)We can infer from the last paragraph that ________.
A.the mine robots will have a very bright future
B.robots in mines will serve much in the automotive industry
C.there will be no need for human workers in mines
D.robots in mines only do some simple jobs now
(4)We can infer from the text that ________.
A.robots cannot do dangerous work in dark areas
B.the mining robots do most of the mining work at present
C.groundhog can discover the presence of dangerous gases
D.experts are trying to make robots help miners with dangerous work

【题目】根据短文理解,选择正确答案。
Most animals have little connection with animals of a different kind, unless they hunt them for food. Sometimes, however, two kinds of animals come together in a partnership (伙伴关系) which is good for both of them. You may have noticed some birds sitting on the backs of sheep. This is not because they want a ride, but because they find easy food in the parasites (寄生虫) on sheep. The sheep allow the birds to do so because they remove the cause of discomfort. So although they can manage without each other, they do better together.
Sometimes an animal has a plant partner. The relationship develops until the two partners cannot manage without each other. This is so in the corals(珊瑚) of the sea. In their skins they have tiny plants which act as “dustmen”, taking some of the waste products from the coral and giving in return oxygen which the animal needs to breathe. If the plants are killed, or are even prevented from receiving light so that they cannot live normally, the corals will die.
(1)Some birds like to sit on a sheep because _______.
A.they can eat its parasites
B.they enjoy travelling with the sheep
C.they depend on the sheep for existence
D.they find the position most comfortable
(2)The underlined word “they” in the last sentence of the first paragraph refers to ______.
A.birds and parasites
B.birds and sheep
C.parasites and sheep
D.sheep, birds and parasites
(3)We learn from the text that corals depend on plants for______.
A.comfort
B.light
C.food
D.oxygen
(4)What does the second paragraph mainly discuss?
A.Some animals and plants depend on each other for existence[
B.Some animals and plants develop their relationship easily.
C.Some plants depend on each other for food.
D.Some animals live better together.

【题目】根据短文理解,选择正确答案。
Next autumn when you see wild geese heading south for the winter flying in a V formation, you might think about what scientists have discovered as to why they fly that way.
As each bird flaps its wings, it creates uplift(提升) for the bird immediately following. By flying in a V formation the whole group adds at least 71% greater flying range than if each bird flies on its own.
People who share a common direction and sense of community can get where they are going more quickly and easily because they are traveling on the push of one another.
When a wild goose falls out of the formation,it suddenly feels the drag and resistance of trying to go alone and quickly tries to get back into the formation to take advantage of the lifting power of the bird in front. When the head goose gets tired,it flies back into the formation and another goose flies to the front. It is wise to take turns doing difficult jobs whether it is people or wild geese flying south.
Wild geese honk (发出雁叫声) from behind to inspire those up front to keep up their speed. What can we learn from this?
When a wild goose gets sick or wounded by gunshots,and falls out of the formation,two other geese will fall out with that goose and follow it down to lend help and protection. They will stay with the fallen goose until it is able to fly or until it dies,and only then will they go on with their own or with another formation to catch up with their group.
(1)Wild geese fly in a V formation in order to________.
A.protect themselves from danger
B.fly more quickly and easily
C.help the sick and wounded
D.fly much higher in the sky
(2)What can we learn from the fifth paragraph?
A.We should try to lead others to move forward.
B.We should give people facing difficulties encouragement.
C.We should believe in those who offer us help.
D.We should care more about the old and sick.
(3)When a wild goose becomes sick or is wounded,________.
A.it will be left alone and will fall on the ground
B.the whole group will stop flying
C.two other geese will stay with it to offer help
D.other geese will honk to give it encouragement
(4)What do we know from the passage?
A.A wild goose can help the one following it by flapping its wings.
B.A person who works alone can work better than one who doesn't.
C.It is not good for wild geese to take turns being the head goose.
D.The wild geese that fall behind are unlikely to catch up with their group.
