A. Attention must be paid to environmental factors.
B. Principles of curing cancers.
C. It will take long to find perfect cures.
D. An important discovery in the research.
E. The causative factor of cancer is very clear.
F. The survival rate differs among patients with various cancers.___________
“I have great confidence that by the end of the decade we’ll know in vast detail how cancer cells arise,” says microbiologist Robert Weinberg, an expert on cancer. “But,” he cautions, “some people have the idea that once one understands the causes, the cure will rapidly follow. Consider Pasteur. He discovered the causes of many kinds of infections, but it was fifty or sixty years before cures were available. ” ____________
This year, 50 percent of the 910,000 people who suffer from cancer will survive at least five years. In the year 2020, the National Cancer Institute estimates, that figure will be 75 percent. For some skin cancers, the five-year survival rate is as high as 90 percent. But other survival statistics are still discouraging—13 percent for lung cancer, and 2 percent for cancer of the pancreas (胰腺) . ___________
With as many as 120 varieties in existence, discovering how cancer works is not easy. The researchers made great progress in the early 1970s, when they discovered that oncogenes, which are cancer-causing genes, are inactive in normal cells. Anything from universe rays to radiation to diet may activate an inactive gene, but how remains unknown. If several oncogenes are driven into action, the cell, unable to turn them off, becomes cancerous. ____________
The exact process involved is still mysterious, but the likelihood that many cancers are initiated at the level of genes suggests that we will never prevent all cancers. “Changes are a normal part of the evolutionary process,” says oncologist William Hayward. Environmental factors can never be totally eliminated; as Hayward points out, “We can’t prepare a medicine against universe rays.” ____________
The prospects for cure, though still distant, are brighter. “First, we need to understand how the normal cell controls itself. Second, we have to determine whether there are a limited number of genes in cells, which are always responsible for at least part of the trouble. If we can understand how cancer works, we can reduce its action. ”
Although many Chinese students say that their knowledge of English grammar is
good, most would admit that their spoken English is poor. Whenever I speak to a Chinese student, they
always say “My spoken English is poor.”I would like to suggest that there may be some reasons for their problems with spoken English.
First, they fail to find suitable words to express themselves due to a limited vocabulary.
However, you can speak with a limited vocabulary, if you choose a positive attitude. Others will follow
You as long as you use the words that you know._. Sometimes they make mistakes
when they are speaking because they are shy and nervous. Yet students should remember
that their goal should be FLUENCY NOT ACCURACY. Your aim in writing is to be accurate
following the rules for grammar and using the right words and spelling them correctly.
However, in speaking your aim is fluency. You want to get your message across, to talk
to someone in English, as quickly and as well as you can, even though sometimes you may
use a wrong word or tense , but it doesn’t matter..
The third reason is that not enough attention is paid to listening . You have one mouth but two
ears！All that hearing is necessary for you to start speaking .
Actively seeking out opportunities to improve their spoken English they passively wait for speaking opportunities to come to them and wonder why their English always remains poor..
| A．The person you are speaking to will understand you and make allowances for any mistakes he hears. |
| B．They may try to avoid making similar mistakes next time. |
| C．Obviously the better answer is to expand their vocabulary . |
| D．If you have this proactive outlook, then you will see English opportunities wherever you go. |
E. However, their spoken English does not have to remain “poor”！
F. Second , they are afraid of making mistakes.
G. The second reason lies in the reluctance of using what has just been learned.
Easy Ways to Keep Your Brain Sharp
Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing. Read on for some techniques worth trying.
1．
People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study. Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or shortterm goals appear to do better. In other words, keep your brain looking forward.
2．Go for a walk.
Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact，exercise produces chemicals that are good for your brain.
3．Learn something new.
Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time. Or go dancing with your friends.
| A．Focus on the future. |
| B．This can be especially harmful to the aged. |
| C．It should be something like learning gardening. |
| D．So take a few minutes each day to do some reading. |
E．But don't worry if your schedule isn't filled with lifechanging events.
F．Luckily, research shows there is a lot you can do to avoid those moments.
G．In other words, when you take care of your body, you take care of your brain.

There are certainly benefits of using a star in a film. It makes the film easier to market. Stars also help sell more tickets and drive DVD sales, which are a big part of studio revenue. However, a star does not guarantee success. The simple fact is that if you pay a star a great deal of money for a film that people don't want to see, then it won't work.

A. Agra Fort
Near the gardens of the Taj Mahal stands the important 16th-century Mughal monument known as the Red Fort of Agra. This powerful fortress of red sandstone encompasses, within its 2.5-km-long enclosure walls, the imperial city of the Mughal rulers.

Taj Mahal is regarded as one of the eight wonders of the world, and some Western historians have noted that its architectural beauty has never been surpassed. The Taj is the most beautiful monument built by the Mughals, the Muslim rulers of India. Taj Mahal is built entirely of white marble. It was constructed over a period of twenty-two years, employing twenty thousand workers. It was completed in 1648 C.E. at a cost of 32 Million Rupees.
C. Keoladeo National Park
