Experts say that if food were a country, it would rank second behind the US as one of the biggest greenhouse gas polluters. The reason is the rising demand for meat. Animal farming is responsible for14.5 percent of global greenhouse gas methane(甲烷) emissions(排放). While cows are the worse contributors, pigs, sheep, donkeys and other animals play a part as well.

Animal agriculture also causes land to become damaged, water to be polluted and forests to get destroyed. With the world population forecast to rise to 9.8 billion by 2050, things are only looking worse for our already decreasing natural resources, While going vegetarian(素食的)would help meat consumption too deep - rooted in most western diets to allow for such a sharp, permanent change. That is why experts are advocating substituting some of the beef, chicken, or pork with ordinary insects！

Insects, which grow into adults within a matter of months, if not weeks, are ready for consumption much faster than domestic(驯养的) animals. They also require much less room，use less water and food, and produce far less greenhouse gas than animals

Of the 1.1 million insect species worldwide, scientists have identified 1.700 as eatable. Among them are ants, grasshoppers, grubs, and earthworms. Just like animals, each insect has a different taste. Tree worms taste just like pork, and grubs are similar to smoked meat

While eating insects might be a new concept for Western people, over 2 billion people worldwide consume insects as a regular part of their diet. Besides being delicious, insects are high in protein, have very few calories, and are free of the saturated(饱和)at found in animal meat. Insects can be prepared in many ways. Creative cooks can use them to cook protein-rich soup make baked treats, and even fry a few with vegetables. So eat insects -both your body and Mother Earth will thank you for it ！

1.Which of the following animals are responsible for the most global methane emissions?

A. Cows B. Pigs C. Sheep D. Donkeys

2.How is the third paragraph mainly developed？

A. By asking questions B. By providing examples.

C. By listing the numbers D. By making comparisons.

3.What do tree worms taste like?

A. Pig meat B. Tomato soup. C. Fresh vegetables. D. Fried chicken.

4.What can be inferred from the last paragraph?

A. Few people eat insects regularly. B. Ordinary insects are high in fat.

C. Saturated fat is harmful to health. D. Insects contain various vitamins

Do you want to live another 100 years or more? Some experts say that scientific advances will one day enable humans to last tens of years beyond what is now seen as the natural limit of the human life span.

"I think we are knocking at the door of immortality(永生)," said Michael Zey, a Montclair State University business professor and author of two books on the future. "I think by 2075 we will see it and that’s a conservative estimate".

At the conference in San Francisco, Donald Louria, a professor at New Jersey Medical School in Newark said advances in using genes as well as nanotechnology（纳米技术）make it likely that humans will live in the future beyond what has been possible in the past. "There is a great push so that people can live from 120 to 180 years," he said. "Some have suggested that there is no limit and that people could live to 200 or 300 or 500 years."

However, many scientists who specialize in ageing are doubtful about it and say the human body is just not designed to last about 120 years. Even with healthier lifestyles and less disease, they say failure of the brain and organs will finally lead all humans to death.

Scientists also differ on what kind of life the super aged might live. "It remains to be seen if you pass 120, you know; could you be healthy enough to have good quality of life?" said Leonard Pooh, director of the University of Georgia Gerontology(老龄学) Center. "At present people who could get to that point are not in good health at all."

1.By saying "we are knocking at the door of immortality", Michael Zey means ________.

A．they believe that there is no limit of living

B．they are sure to find the truth about long living

C．they have got some ideas about living forever

D．they are able to make people live past the present life span

2.Donald Louria's attitude towards long living is that ________.

A．people can live from 120 to 180 years

B．it is still doubtful how long humans can live

C．the human body is designed to last about 120 years

D．it is possible for humans to live longer in the future

3.The underlined "it"（paragraph 4）refers to ________.

A．a great push

B．the idea of living beyond the present life span

C．the idea of living from 200 to 300 years

D．the conservative estimate

4.What would be the best title for this text?

A．Living Longer or Not

B．Science, Technology and Long Living

C．No Limit for Human Life

D．Healthy Lifestyle and Long Living

“It is one of the few bright spots in the Chinese economy，” says Zeng Ming. He is talking about e­commerce. Mr. Zeng, the chief strategy officer for Alibaba, a giant Chinese Internet firm, predicts that digital transactions on his firm's platforms will top 1 trillion yuan($159 billion) this year—more than Amazon's and eBay's combined. That is a bold claim, but consider what happened on Singles Day.

Invented a few years ago by students and seized upon by digital marketers, this festival for lonely hearts falls annually on the 11th day of the 11th month(since 1 is the loneliest number). It is like St Valentine's Day, only worse. Singletons show each other with tender gifts: a barrage of pearls; a storm of sweets.

This November 11th they spent a surprising 19 billion yuan on Alibaba's online platforms—a fourfold increase on a year ago, and more than double what Americans spent online last Cyber Monday(the Monday after Thanksgiving, when retailers urge Americans to shop online). About 100 million purchases were logged, accounting for 80% of the packages shipped that day. Couriers(快递员) were buried in parcels.

So life is good for China's e­tailers. Then? Not exactly. The number of digital marketers is increasing and online sales are booming. Consumers are enjoying lower prices, better service and more variety. The problem? The pressure on profits in Chinese e­commerce is worse than in America, reckons Elinor Leung of CLSA, a broker. “Almost no one makes money，” she says.

The fiercest battles are being fought between online retailers and their bricks­and­mortar(实体的) rivals. Dangdang, a firm that resembles Amazon, and 360buy, another online retailer, have cut prices fiercely. Tencent, a cash­rich online giant known for its instant­messaging software, is splashing out to win market share. 360buy has also just raised $400 millon from investors to do the same. But it is unclear how much longer such firms can burn through capital.

1.What's the best title of this passage?

A．The Ambition of Alibaba

B．Fierce　 Competition between Retailers

C．A New Festival for the Singles

D．Chinese Booming E­commerce

2.According to Zeng Ming, this year Alibaba will ________.

A．outweigh Amazon and eBay in worldwide influence

B．rank top among all the Internet firms

C．have more than 159 billion dollars' sale

D．create another sales miracle just like the one on Singles Day

3.How many packages were shipped on November 11th from Alibaba's online platforms?

A．About 80 million.　     B．About 100 million.

C．About 125 million.　     D．About 180 million.

4.What's the author's attitude towards online retailers in China?

A．Optimistic.　     B．Concerned.

C．Sympathetic.　     D．Indifferent.
