Are GM（转基因的) foods safe for people? Can they help solve the poverty problem? They have been the subjects of a hot debate.
This debate is related to increasing challenges from rising climatic change, population growth, urbanization（城镇化), and natural resource consumption. According to the Food and Agriculture Organization, food production needs to increase by 60 percent by 2050 in order to feed 9 billion people. Scientists and policymakers are searching for effective ways to gain nutritious food, for today and future. Unlike previous agricultural methods (such as the Green Revolution), GM crops are to fight food safety and poverty challenges.
The great expansion of GM crop varieties over the last two decades can be seen easily. The total area devoted to GM crops has increased 100 times from 1.7 million hectares in 1996 to 170 million hectares in 2012. Developing countries now grow more GM crops than developed countries (in terms of area), largely driven by Brazil’s rapid adoption of GM crops. China is home to about 4 percent of the total global area devoted to GM crops. Beans, corn, and cotton are main global GM crops, while China’s focus is on cotton, papaya, and poplar.
Recently, a scientific study shows that GM crops are safe for people and the environment. According to a 2010 report on the safety of GM crops by the EU, “the main conclusion to be drawn from the efforts of more than 130 research projects, covering a period of more than 25 years of research, and involving more than 500 research groups, is that biology methods, are not more risky than traditional planting technologies, for example.” Other international and national scientific bodies, such as the World Health Organization, have reached the same conclusion.
1. Nowadays, people are developing GM foods mainly to fight against______.
A. urbanization
B. population growth
C. rising climatic change
D. natural resource consumption
2. As for GM crops, what do people mainly focus on ?
A. Food production. B. Food nutrition.
C. Food safety. D. Food variety.
3. What does Paragraph 3 talk about?
A. More GM crops in developing countries.
B. Less GM crops in developed countries.
C. Rapid adoption of GM crops in Brazil.
D. The expansion of GM crop varieties of the world.
4. From a recent scientific study, we can infer that______.
A. traditional planting technologies are more risky
B. the safety of GM crops has been proved in many ways
C. the safety of GM crops was reported by the EU in 2010
D. present GM crops are safe for people and the environment
5. What’s the writer’s attitude towards GM crops?
A. Supportive. B. Opposed.
C. Unknown. D. Indifferent.

Animals seem to have the sense to eat when they are hungry and they do not eat more than their bodies need．It has been demonstrated（证明）that rats will, when given a choice over a period of time, prefer water with vitamins(维生素) to water without vitamins even though there is no difference in taste or smell between the two water bottles．When a fragrant（香的）flavor（作料）was added to the vitamin-enriched water, the rats did seem to prefer it and kept drinking it ,even after the vitamins were switched to the clear water．In time, however, they broke the habit and went back to where the necessary vitamins were．
In a classic experiment, babies of 6 to 12 months old were placed in a cafeteria（自助） feeding arrangement, with a wide selection of baby food before them．They were given whatever food they pointed to or appeared interested in．We are told that at first they showed some unusual eating patterns, but that over a period of time they managed to select well-balanced diet．
So, in choosing food, rats and babies do seem to know and act on what's best for them．Apparently, there is a kind of “body wisdom”, which humans soon lose．Most of us do not eat as wisely as we could．Many of our food preferences are culturally determined and influenced by long-formed habits．Some people eat fox, dog and blackbirds, while we eat cows and pigs．So what people eat and how much they eat seems to be greatly influenced by what is going on around them．
1.In the experiment on rats, a fragrant flavor was added to the rats’ drinking water to _____________ .
A．encourage rats to drink vitamins-enriched water
B．test whether rats know which drink is good for them
C．find out rats’ preference in flavor
D．demonstrate the vitamins are tasteless
2.According to the passage ,adults eating habits differ from those of babies because_________．
A．adults know better than babies what kind of food are good for their health
B．adults usually cannot resist the temptation of various delicious foods
C．adults have more choices of food than babies in eating patterns
D．adults' eating habits are closely related to the social and cultural customs
3.The author implied in the passage that most of us_________．
A．eat a balanced diet
B．choose the food that is of nutrition
C．have the habits influenced by the surroundings
D．like to eat the food with a fragrant flavor．
4.As far as their eating habits are concerned, babies and rats are similar in that_________．
A．both prefer flavored food and drink
B．both have the wisdom to choose a balanced diet
C．both have the same eating patterns
D．both develop a taste for the same kinds of flavors

Lions are opportunists. They prefer to eat without having to do too much work. When resting in the shade, they are also watching the sky to see what is flying by, and even in the heat of the day they will suddenly start up and run a mile across the plains to find out what is going on. If another animal has made a kill, they will drive it off and take the dill for themselves. A grown lion can easily eat 60 pounds of meat at a single feeding. Often they eat until it seems painful for them to lie down.
The lionesses (母狮) , being thinner and faster, are better hunters (猎手) than the males (雄狮). But the males don’t mind. After the kill they move in and take the rest share.
Most kills are made at night or just before daybreak. We have seen many, many daylight attempts but only ten kills. Roughly, It’s about twenty daytime attempts for one kill.
When lions are hiding for an attack by a water hole, they wait patiently and can change at any second. The kill is the exciting moment in the day-to-day life of the lion, since these great animals spend most of their time, about 20 hours a day, sleeping and resting.
Lions are social cats, and when they are having a rest, they love to touch each other. After drinking at a water hole, a lioness rests her head on another’s back. When walking, young lions often touch faces with older ones, an act of close ties among members of the group.
1.By describing lions as “opportunists” in the first paragraph, the author means to say that lions ________.
A. are cruel animals B. are clever animals
C. like to take advantage of other animals D. like to take every chance to eat
2.According to the text, which of the following is true?
A. Lions make most kills in the daytime.
B. Males care more about eating than active killing.
C. Lions are curious about things happening around them.
D. It doesn’t take lions too much time to make a kill.
3.How can we know that lions are social animals?
A. They depend on each other. B. They look after each other well.
C. They readily share what they have. D. They enjoy each other’s company.
4.What would be the best title for the text?
A. Powerful Lions B. Lions at Work and Play
C. Lions, Social Cats D. Lions, Skilled Hunters
