I can’t tell you the exact time when I will get there ._______,I’ll be there as early as I can .

Long time ago, there was a farmer who lived with his daughter. A young man fell in love with the farmer’s beautiful daughter and wished to   36   her. One day, he went to the farmer to   37   his permission. The farmer looked at him and said, “ Guy, stand out in that  38   . I’m going to release (释放)  39  bulls, one at a time. If you can   40   the tail of any one of the three bulls, you can marry my daughter.”

41  , the young man got out and stood in the field,   42    the first bull. The barn（牛棚） door   43     and out came the biggest bull that he had ever seen. He   44     that one of the next bulls had to be a better   45     than this one, so he ran over to the side and let the bull   46    .

A few   47     later, the barn door opened again. Unbelievable! The young man had never seen any bull so   48     and fierce as this one in his life. It stood there, pawing（扒） the   49   and eyeing the young man. “ What the next   50    was like ? It had to be a better choice than this one,” he thought. He let the bull pass through again.

The door opened a third time. A   51     came across the young man’s face. This was the weakest bull that he had ever seen. “ This one was my bull,” he   52     to himself. As the bull came running by, he positioned himself just right and   53     at just the exact moment. He threw his hands to catch ...... But to his   54    , the bull had no tail.

Life is full of opportunities.   55    catch the first one.

As they migrate（迁移) , butterflies and moths choose the winds they want to fly with, and they change their body positions if they start floating in the wrong direction. This new finding suggests that insects may employ some of the same methods that birds use for traveling long distances. Scientists have long thought that insects were simply at the mercy of the wind.

Fascinating as their skills of flight are, migrating behavior has been difficult to study in insects because many long distant trips happen thousands of feet above ground. Only recently have scientists developed technologies that can detect such little creatures at such great heights.

To their surprise, though, the insects weren't passive travelers on the winds. In autumn, for example, most light winds blew from the east, but the insects somehow sought out ones that carried them south and they positioned themselves to navigate directly to their wintering homes.

Even in the spring, when most winds flowed northward, the insects didn't always go with the flow. If breezes weren't blowing in the exact direction they wanted to go, the insects changed their body positions to compensate. Many migrating birds do the same thing.

The study also found, butterflies and moths actively flew within the air streams that pushed them along. By adding flight speeds to wind speeds, the scientists calculated that butterflies and moths can travel as fast as 100 kilometers an hour. The findings may have real-world applications. With climate warming, migrating insects are growing in number. Knowing how and when these pests move could help when farmers decide when to spray their crops.

Ena was very pretty and kind. ____41____, when she woke up and stretched(伸展) her arms above her head one day she felt a bald patch in her hair. Then she ___42____ lots of hair on her pillow. Over the next few months her hair continued to ___43 ___. Ena felt shock and sad. And ___44____ she lost all her hair and she hated being ___45___. She was angry with her body and she was ___46___ that people might laugh at her at school.

But then, Ena had a wonderful day on January 9^th! It was her birthday and she got a(n) ___47___ present---- a wig(假发)！Trying on the wig made Ena feel very happy. She felt ___48____ again. The first Ena went to school, people asked why her ___49___ was different, and whether she had a wig on. Ena replied, “No.” She was worried because did notice the ___50___ and she was anxious that someone might try to ___51____ her wig off.

Then her classmates got used to it and stopped asking her questions. But as time went by, she began to feel that the ___52___ she kept about her hair was too big and making her feel ___53___. She wanted to share it with her. So, one Friday, Ena went to the front of the classroom, and she told everyone ___54___, “I have a wig on.” She told them about her ___55___-----alopecia(秃头症) and ___56____ that all her hair had fallen out, including her eyelashes and eyebrows. Everybody’ eyes widened and some people put their hands up to their faces when Ena took her wig off. They listened to her story ____57___, sitting very quietly, and when Ena finished, everybody clapped. And they started to say ___58___ things while Ena passed the wig around for everyone to touch. Finally, the whole class and the head teacher ___59___ Ena to do her lessons without her wig on.

It’s not ___60____ having no hair, and Ena has positive days as well as other days when it is hard. However, she always remembers what her teacher told her, “It doesn’t matter that you don’t have hair; you’re still the same person inside.”

20.A easy         B. acceptable    C. hopeful           D. useful

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.

1.___________

“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. ”

2.____________

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) .

3.___________

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.

4.____________

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.”

5.____________

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. ”
