Many jobs must be done with two people. One person takes the lead. The other helps. So it is with the human body. Much of our body depends on the cooperation between substances. When they work together, chemical reactions take place smoothly. Body systems are kept in balance.

Some of the most important helpers in the job of good health are the substances we call vitamins. The word “vitamin” dates back to Polish scientist Casimir Funk in 1912. He was studying a substance in rice. Funk believed the substance belonged to a group of chemicals known as amines (胺类). He added the Latin word “vita”, meaning life. So he called the substance a “vitamine”—an amine necessary for life.

Other studies found that not all vitamins were amines. So the name was shortened to vitamin. But Funk was correct in recognizing their importance.

Scientists have discovered 14 kinds of vitamins. They say vitamins help to carry out chemicals changes within cells. If we do not get enough of the vitamins, we are at risk of developing a number of diseases. This brings us back to James Lind of Scotland. In the 1740s, Lind was a doctor for the British Navy. He was investigating a problem that had existed in the Navy for many years.

The problem was the disease scurvy(坏血病). The sailors were weak from bleeding inside their bodies. Even the smallest wound would not heal. Doctor Lind thought the sailors were getting sick because they failed to eat some kinds of foods when they were at sea for many months.

Doctor Lind separated twelve sailors who had scurvy into two groups. He gave each group different foods to eat. One group got oranges and lemons. The other did not. The men who ate the fruit began to improve within seven days. The other men got weaker.

However, which foods should be eaten to keep us healthy? Let us look at some important vitamins for these answers.

1.Why was the name “vitamine” shortened to “vitamin”?

A. Because Funk was totally wrong.

B.Because few vitamins were amines.

C. Because there were new findings.

D. Because the latter was easy to remember.

2.The underlined word “This” in the fourth paragraph probably refers to that _______.

A. people tend to develop many diseases

B. lack of the vitamins causes disease

C. vitamins help chemical changes within cells

D. it is common for people to get no enough vitamins

3.Doctor Lind proved eating fruits can prevent scurvy by means of _______.

A. comparing　　 B. analyzing　　 C. surveying　　 D. questioning

4.What is the main topic of the passage?

A. Food to keep us healthy.

B. The benefits of vitamins.

C. Research into scurvy.

D. Facts about vitamins.

Alibaba started taking the lead in China by connecting big Chinese manufacturers(制造商) with big buyers across the world. Its business-to-business site, Alibaba.com allowed business to buy almost everything. Alibaba’s advantage wasn’t hard to judge: size. Alibaba is just big, even by Chinese standards. Its market attracts 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 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(物品) 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 acts as a bridge between the buyers and sellers.

D. 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 money than retail.

4. What is the passage mainly about?

A. Shopping online in China is TaoBao.

B. How the author purchases online in China.

C. Shopping online goes beyond traditional shopping.

D. Alibaba influences people’s daily purchase in China.
