In the early days of sea travel, seamen on long voyages lived exclusively on salted meat and biscuits. Many of them died of scurvy (坏血病), a disease of the blood which causes swollen gums (牙龈), livid white spots on the flesh and general exhaustion. On one occasion, in 1535, an English ship arrived in Newfoundland with its crew desperately ill. The men’s lives were saved by Iroquois Indians who gave them vegetable leaves to eat. Gradually it came to be realized that scurvy was caused by some lack in the sailors’ diet and Captain Cook, on his long voyages of discovery to Australia and New Zealand, established the fact that scurvy could be prevented by the supply of fresh fruit for the sailors.

Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing. These elements are called “vitamins”. Quite a number of such substances are known and they are given letters to identify them, A, B, C, D, and so on. Different diseases are associated with shortages of particular vitamins. Even a slight lack of Vitamin C, for example, the vitamin most plentiful in fresh fruit and vegetables, is thought to increase significantly our susceptibility (敏感度) to colds and influenza.

The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruit and green vegetables. It is only when people try to live on a very restricted diet, say during extended periods of religious fasting (斋戒), or when trying to lose weight, that it is necessary to make special supply to make up for the missing vitamins.

1.Scurvy is a disease that is caused by 　　　 .

A.salted meat and biscuits B.exhaustion

C.lack of some essential substances D.need of fresh vegetables and fruits

2.To avoid such disease as scurvy, it’s better for us 　　　 .

A.not to eat much salted meat

B.to supply our diet with various vitamin pills

C.to have more fresh fruit and vegetables

D.to develop a good dietary habit

3.Based on the passage we can safely conclude that if our diet is not comprehensive enough, 　　　 .

A.vitamin pills are of no use

B.nutritious food might be unhealthy

C.vegetable leaves can be a good treatment

D.religious fasting may help out a lot

4.Which of the following sentences best expresses the main idea of the passage?

A.Shortages of Vitamin C may cause serious diseases.

B.Fresh fruit and green vegetables contain enough nutrition that is necessary for a healthy body.

C.Vitamins play a vitally important role in people’s health.

D.A good mixed diet normally supplies sufficient vitamins for us.

It was on the early afternoon of a mid-October day in 2012. Bismark Mensah, who came to America several months ago, was collecting carts (手推车) outside a Walmart in Federal Way. It was a part-time job for him. He earned $9.05 an hour in charge of getting carts out of the parking lot.

He was used to finding stuff in carts that customers had somehow forgotten — keys, credit cards, wallets. And he turned them into a customer service. But a particular item stood out. It was a white envelope with a clear window in the middle, and there was a lot of cash in it, around $20,000. Mensah turned them into customer services.

Because of what he did that afternoon, Mensah is now the winner of Walmart’s national 2013 “Integrity(正直) in Action Award”.

Bismark Mensah says that since the story ran, he has become the model the youth in Ghana (his native country).

He is now employed full-time at the Federal Way Walmart, earning $10.95 an hour, up from the $9.05 an hour he earned working part-time.

Mensah, 33, no longer collects carts and such. He is in the backroom, dealing with inventory(库存). “I want to learn everything about operating a store like Walmart store,” he says. He plans to return to Ghana to run some shops owned by his family. He also plans to go to college and earn a degree in business administration.

Scientists around the world are striving for effective detection of cancer in the early stages,which is a group of diseases involving abnormal cell growth with the potential to invade or spread to other parts of the body,and a Chinese scientist may have found a quick way of knowing whether malignant tumors（恶性肿瘤）exist in a patient's body,with just one drop of blood.

Malignant tumors in early phases can be cured.However,it's extremely difficult to be aware of cancer in its early stages,as patients don't show obvious symptoms and thus it can only be found in its later stages,which is already too late,so to detect cancer early remains a global challenge for scientists.

Back in 1989,scientists have found a kind of heat shock proteins (HSP),named Hsp90α,which existed in human bodies and can be used as a cancer biomarker detection kit.Scientists around the globe have been working on it since then,and more than 10,000 journals have been published on accredited magazines,yet no one has actually turned their research results into medical products.

However,Luo Yongzhang and his team in Tsinghua University's School of Life Sciences in Beijing seemed to have cracked the code,after working on the problem since 2009.The team has produced an artificial Hsp90α protein for clinical use that gains structural stability by regrouping proteins.The test kit can diagnose multiple kinds of cancer by analyzing a drop of human blood.This means they are able to "create" the protein,in any quantity,and at any time they wish to.

The kit has since been used in clinical trials involving 2,347 patients at eight hospitals in China.It was the first clinical trial in the world to test if the protein could be a useful tumor biomarker for lung cancer,and it succeeded. Now,the kit has been approved to enter the Chinese and European markets,24 years after Hsp90α was discovered.

1.Why is cancer hard to cure?

A. Malignant tumors are found too late.

B. Malignant tumors spread too quickly.

C. Its symptoms are shown in early stages.

D. No proper treatment can be applied to it.

2.What do we learn about Hsp90α from Paragraph 3?

A. It was created by scientists in 1989.

B. All magazines have covered the topic.

C. There has been a medical product about it.

D. It can serve as a cancer detection approach.

3.How does the Chinese kit diagnose cancer?

A. By regrouping proteins.

B. By cracking cancer’s code.

C. By breaking down one drop of blood.

D. By producing an artificial Hsp90α protein.

4.It can be inferred that a European with lung cancer in early phases .

A. can’t be cured in the end

B. can be diagnosed with it in time

C. has to be examined in China

D. expects the kit to come into the market

Patients in the early stages of Alzheimer’s disease often struggle to remember recently learned information, meaning they forget things like important appointments or where they left their keys. But it seems that these memories are not lost. They are still filed away in the brain somewhere; they just can’t be easily accessed.

Now, researchers at MIT have developed a means of getting back memories in mice suffering from Alzheimer’s. The method relies on a technique that uses light to control genetically modified neurons (转基因神经元). Currently it is too early to be used in human trials as it involves inserting light emitting (发光) equipment into the subjects’ brains, but the same principles still apply, the researchers said.

“The important point is that this is evidence of concept. That is, even if a memory seems to be gone, it is still there. It’s a matter of how to get it back,” said senior researcher Susumu Tonegawa.

The team took two groups of mice, one genetically engineered to develop Alzheimer’s and one healthy. They then placed them into a room and gave them a mild electric shock. All of the mice showed fear when put back in an hour later. When placed in the room a third time several days later, the Alzheimer’s mice acted normally. They had forgotten the shock.

The researchers were then able to bring back the memory of the shock by activating (激活) the cells in which the memories were stored. Even when the mice were put into an unfamiliar room, they showed fear when the cells associated with the shock were activated.

“Short-term memory seems to be normal, on the order of hours. But for long-term memory, these early-Alzheimer’s mice seem to be damaged,” said lead researcher Dheeraj Roy. “Directly activating the cells that we believe are holding the memory helps them get it back. This suggests that it is indeed an access problem to the information, not that they’re unable to learn or store this memory.”

1.What can we learn about the researchers at MIT?

A. They are the pioneers of brain research.

B. They have used the method in human trials.

C. They can cure Alzheimer’s using the new method.

D. They can get back memories in mice with Alzheimer’s.

2.Why did the Alzheimer’s mice behave normally a third time?

A. They failed to remember the electric shock.

B. They were accustomed to the situation.

C. They managed to overcome the fear.

D. They activated the association.

3.For long-term memory, the early Alzheimer’s mice _______.

A. can activate their blood cells

B. can’t learn new tricks well

C. can easily get back their memory

D. can’t access the information stored

4.The main purpose of the text is to _______.

A. introduce a method of a research

B. report the latest discovery about a disease

C. give advice on how to improve memory

D. explain how our brain stores information
