Everyone knows that death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two periods—clinical or temporary death and biological death. Clinical death occurs when the important organs, such as the heart or lungs, have stopped to function, but have not suffered permanent damage. The organism (有机体) can still be revived. Biological death occurs when changes in the organism lead to the “breaking up” of important cells and tissues. Death is then unchangeable.
Scientists have been seeking a way to lengthen the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic (麻醉的) sleep. By slowing down the body’s metabolism (新陈代谢), cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery (动脉). The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous (自发的) breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe (注射器) and ran with it around the room. It showed that Keta had nothing different from any other healthy animal.
1.For a person who suffers from the clinical death, _________.
A.he can’t avoid final death
B.he is still very much alive
C.his most important organs are damaged
D.he still has the possibility of getting back to life
2.Scientists try to make the time of clinical death longer in order to ________.
A.cool the organism
B.slow down the body’s metabolism
C.delay the coming of biological death
D.bring important cells and tissues back to active life
3.How did the scientists put Keta into clinical death?
A.By surrounding her body with ice-bags and draining her blood.
B.By lowing her blood pressure and stopping her heart from beating.
C.By putting her to sleep, lowering her temperature and draining her blood.
D.By draining her blood, lowering her blood pressure and stopping her breathing.
4.Which of the following indicates that Keta is a healthy animal after the experiment?
A.Her heart beat again.
B.She seized the syringe and ran away with it.
C.She regained her normal breath.
D.She opened her eyes and lifted her head.
Alibaba starts taking the lead in China, simply enough, by connecting big Chinese manufacturers (制造商) with big buyers across the world. Its business-to-business site, Alibaba.com allows business to buy almost everything. Alibaba’s advantage isn’t hard to identify: size. Alibaba is just big, even by Chinese standards. Its marketplaces attract 231 million active buyers, 8 million sellers, 11.3 billion orders a year — and Alibaba is just the middleman. It encourages people to use its markets — not charging small sellers a percentage of the sale.
If you want a quick look into the influence of Alibaba on daily Chinese life, take my experience. I moved to Beijing almost a year ago and quickly got tired of visiting small stores across the crowded, polluted city of 20 million people in search of new electronics, bathroom furnishings, and anything else my wife wanted. “You’re looking for what exactly? Why not try it?” my Chinese teacher asked me one day. With that, my wonderful new relationship with Alibaba began.
Alibaba’s original business-to-business model now is second to consumer buying. Chinese retail (零售) buying makes up 80% of Alibaba’s profit, and leading that group is Taobao, with 800 million items for sale and the most unbelievable selection of things you’ll ever find. TMall.com is Alibaba’s other big site, where you can find brand name goods from Nike and Unilever near the lowest prices. What I have a hard time explaining to friends and family back in the U.S. is how China has gone beyond traditional shopping — big-box retailers especially — in favor of online purchases on Taobao and a few other sites. In smaller towns than Beijing, where big retailers have not yet traveled, shopping online is shopping, and shopping is Taobao.
I have a list of some of my recent purchases on Taobao for a sense of how wide the marketplace is. Almost everything arrived a day or two after ordering with free shipping. I’m not even a big buyer, because I need friends to help me search the Chinese-language site. When I was searching my purchase history on my Chinese teacher’s iPad, which helps me buy goods, I looked through with great difficulty about 10 of her purchases for every one of mine.
1.Alibaba’s advantage mainly lies in _________.
A.its low price B.its big size
C.its not charging small sellers D.its business-to-business service
2.What can we learn from the underlined sentence in the passage?
A.Alibaba will continue to develop.
B.Alibaba stands out as the best online site.
C.Alibaba is of middle size among all the online sites.

3.What can be inferred from the passage?
A.TMall.com provides more profit than Taobao.
B.The author’s Chinese teacher is also an online purchase lover.
C.Taobao has no obvious advantage over other similar online sites.
D.Alibaba’s business-to-business service earns more than retail now.
4.What is the passage mainly about?
A.Shopping online is Taobao.
B.How the author purchases online in China.
C.Alibaba greatly influences people’s daily purchase in China.
D.The influence of shopping online goes beyond traditional shopping.
La La Land is a 2016 American musical romantic drama film written and directed by Damien Chazelle, starring Ryan Gosling and Emma Stone as a musician and an aspiring (有抱负的) actress who meet and fall in love in Los Angeles. The film’s title refers both to the city of Los Angeles and to the idiom for being out of touch with reality.
Chazelle wrote the screenplay in 2010 but did not find a studio willing to finance the production without changes to his design. Following the success of his 2014 film Whiplash, the project was picked up by Summit Entertainment. La La Land was first showed at the Venice Film Festival on August 31, 2016, and was released in the United States on December 9, 2016. It has gained over $432 million worldwide on a production budget of $30 million. La La Land took more than £6 million in its first weekend in UK cinemas, nearly £5 million more than any other film.
La La Land received great acclaim from critics and was regarded as one of the best films of 2016. Critics thought highly of Chazelle’s screenplay and direction, Gosling and Stone’s performances, and Justin Hurwitz’s score (配乐). It won in every category it was nominated (提名) for at the 74th Golden Globe Awards, with a record-breaking seven wins, and received 11 nominations at the 70th British Academy Film Awards, winning five. It received 14 nominations at the 89th Academy Awards, tying the record for most nominations with Titanic (1997) and All About Eve (1950), and won the awards for Best Comedy, Best Director, Best Actor, Best Actress, Best Screenplay, Best Original Score, and Best Original Song.
