Cancer is a terrible disease. Every year in the UK, more than 330,000 people get cancer, and doctors usually use a kind of therapy called radiotherapy to treat people. This treatment uses high energy X-rays to destroy the disease, but the effects of treatment can be nearly as bad as the cancer. As the X-rays destroy the cancer cells, they also damage healthy cells that are next to them. It’s like using a shotgun to kill an insect. When really important parts of a person’s body are hurt by the X-ray energy, it can have very bad results. It can also make more cancer grow in the damaged places in the future.
A new therapy that uses protons(質(zhì)子) instead of X-ray energy could be the answer to the problem. In a project called PRaVDA, scientists from the UK and South Africa are working to this. If X-ray energy is like a shotgun, then protons can work more like a laser. Scientists can make protons travel through someone’s body without hurting them, and only damage the cancer.
The PRaVDA scientists use computers to make a 3-D model of the cancer cells to make sure the protons go to the right places. “It’s more accurate,” said Michaela Esposito, PhD, from the University of Lincoln.
Building this technology was very difficult, though. Professor Nigel Allinson from the University of Lincoln, the project leader, has put together a team of many different kinds of scientists with different skills. Those skills were all needed to make what he calls “one of the most complex” medical machines ever. It’s also 10 times more expensive than X-ray radiotherapy. Even so, Allinson believes that most cancer treatment will be done by protons in the future. “I think it will improve the quality of life of many cancer patients,” he says.

3.According to Professor Allinson, the new therapy ________.
A. will enable cancer patients to enjoy a better life
B. will cure most cancers in the future
C. will ensure that cancer patients live longer
D. will replace radiotherapy completely
4.What can be inferred from the text?
A. Science and technology are a double-edged sword.
B. Not every cancer patient will be able to afford proton therapy.
C. Radiotherapy is completely the wrong way to cure cancer.
D. The complex medical machine mentioned will soon be put into use.

Some pigs lend to be optimistic while others have a more pessimistic view, according to a new research that is meaningful to animal welfare. The study, published in the journal Biology Letters, is the first to show that mood and personality interact in an animal, influencing judgment.
Asher, a researcher at the University of Newcastle's Institute of Neurowcience, and her team housed groups of pigs in the two types of environments. One reflected sandard commercial conditions and the other was cushier with more space and plenty of sell, deep straw. After the pigs got accustomed to these new homes over a few weeks, the rescarchers picked 18 pigs from each type of housing arrangement to train and test their judgment.
"To do this, we trained each pig that in one corner of a training room there would be a bowl with chocolate sweets — specifically M&Ms, pigs love M&Ms — and in a bowl at the opposite side of the room there would be a bowl that would contain coffee beans, which pigs find bitter-tasting," senior author Lisa Collins of the University of Lincoln's School of Life Sciences said.
Over a number of training trials, pigs learned to go to the bowl reliably when it was in the corner where they had figured out to expect M&Ms. On the contrary, they quickly learned to avoid the bowl when it wasn't in the corner where they would expect to find the coffee beans.
The rescearchers next placed an unfamimliar bowl in different locations, to see how the pigs would react. Some gaily dashed to the bowl no matter what, exhibiting optimism that it would contain their favorite foods. Others, however, behaved as though they expected it to contain coffee beans, displaying pessimism.
The findings suggest that a one-size-fits-all answer to animal welfare issues does not exist. Even if pigs are just equal to bacon or other meal for some people, there is still cause for concern. Students have suggested that how an animal is treated during its lifetime can directly affect meal quality and taste.
1.What was the study devoted to figuring out?
A. The influence of pigs' living environment.
B. The influence between humans and pigs.
C. The didferences of two types of pigs' personality.
D. The relationship between pigs' mood and judgment.
2.What does the underlined word “cushier” in Paragraph 2 mean?
A. simple. B. more comfortable.
C. non-profitable. D. less free.
3.Which bowl can test whether a pig is optimistic or pessimistic?
A. The bowl with chocolate sweets.
B. The bowl containing coffee beans.
C. The bowl full of both sweets and beans.
D. The bowl unfamiliar to two types of pigs.
4.What do the findings of the new research imply?
A. People should treat pigs equally.
B. People's health relies on meat quality.
C. People should meet pigs' various needs.
D. People's attitude toward pigs is totally wrong.

As it is often the case, when people are attending meetings, having meals or waiting for buses, you can always find them addicting to their phones, completely ignoring others.
This is really a common phenomena in our life. The reason is why smart phones nowadays can be used for people to play mobile games and kept in touch with friends through QQ and WeChat. Therefore, too much exposure to phones are bad for people in terms of health. Moreover, people involved in phones fail to communicate well with these around them.
As far as I am concerned, people should wisely make use of their phones to help their work and study. Meanwhile, care much about their family and friends rather than mobile phones.

But don't stop on the first try! Eventually, you can look at fear in the eyes and say, "Go on, I'm not scared!"
2. 3.
Make sure this hobby is not linked to your career; you have to relax and relieve your stress while performing this. Some examples might be cooking, sewing, painting and so on. Apart from helping you challenge yourself, taking a class for your hobby may also give you extra income.
3.Set aside at least nine minutes a day for physical exercise.
4. A simple 9-minute run around your neighborhood can do wonders for yourself.Exercise can not only help you maintain your regular weight, but also make you feel better about yourself.
4.Travel and allow yourself to be interested in new people.
