Counting the hairs on your head would be very difficult. Many have tried, but most people give up after losing count or getting bored! However, scientists say people have more than 100,000 hairs on their heads on average. Of course, this number is different from person to person. Some people have much more hair than others.
What causes hair loss? There are many reasons, such as stress, illness and styling. It also runs in families. Besides, many people simply lose hair as they grow older. To avoid losing hair, you should wash your hair correctly and condition（养护）your hair to help keep your hair healthy. It’s also important to be gentle when brushing or combing hair.
Hair loss is not the same as daily shedding（脱落）. People lose an average of 50 to 100 hairs a day. It’s normal. If you are losing more hair than average, talk to the adults you trust. They can help you decide whether to ask a doctor for help.
Why do humans have hair on their heads? Most other mammals（哺乳动物）have thick fur（毛）covering their whole bodies. While humans grow small and fine（细微的）hairs on much of their skin, it’s much thicker on the top of the head. Scientists say the answers come down to evolution. Humans probably evolved without fur because they have more sweat glands（汗腺）than other mammals. Humans walk upright on two legs. Therefore, the top of their heads needs protection from the sun. This is why people have more hair on their heads than on the rest of their bodies. The hair also helps keep heat in cold weather and keep a healthy body temperature.

Jane Goodall is one of the most well-known scientists in the world. Much of the information we have today about chimpanzees comes from the research of Jane Goodall.
Jane Goodall was born in London in 1934. She became interested in animals and animal stories when she was a very young child. She always dreamed of working with wild animals. When she was eleven years old, she decided that she wanted to go to Africa to live with and write about animals. But this was not the kind of thing young women usually did in the 1940s. Everybody was laughing except her mother. “If you really want something, you work hard, you take advantage of opportunity, you never give up, you find a way,” her mother said to her. The opportunity came at last. A school friend invited her to Africa. Jane worked as a waitress until she had got enough money to travel there.
In 1957, Jane Goodall traveled to Africa. She soon met the well-known scientist Louis Leakey and began working for him as an assistant. He later asked her to study a group of chimpanzees living by a lake in Tanzania. Very little was known about wild chimpanzees at that time.
Jane spent many years studying chimpanzees in this area of Africa. It was not easy work. They were very shy and would run away whenever she came near. She learned to watch them from far away using binoculars. Over time, she slowly gained their trust(信任). She gave the chimpanzees human names such as David Graybeard, Flo and Fifi. Watching the chimpanzees, she made many discoveries. They ate vegetables and fruits. But she found that they also eat meat. A few weeks later, she made an even more surprising discovery. She saw chimpanzees making and using tools(工具) to help them catch insects.
Jane Goodall has written many books for adults and children about wild chimpanzees. Her most recent book is called Hope for Animals and Their World. It tells about saving several kinds of endangered animals.根据短文内容完成句子（每空限填一个单词）。

Lake Victoria is the largest lake in Africa. It is also the second largest lake in the world. It is an important lake because it is one of the sources(源头) for the longest river in the world, the Nile River. Lake Victoria provides a source of water, food, and power(电力) for several African countries. Lake Victoria is a big part of African life.
Unfortunately, Lake Victoria has a problem. It is shrinking. There are several power stations at Lake Victoria in Uganda. These are on the Nile River, and besides producing power, they keep the water of the lake at a certain level. For the past forty years, that level has been 11.9 meters. Over the last several years, the water level has dropped by about 2.5 meters. There seem to be several reasons for this drop.
One possible reason is drought(干旱). Drought has been very bad in the area since 2000. Lake Victoria gets all of its water from rain, so the drought means less water in the lake.
However, some environmentalists believe that the real problem is the power plants(工厂) on Lake Victoria. Uganda depends on those power plants for most of its power, and they made the power plants larger in 2000. Many people believe the power plants have been taking too much water off Lake Victoria. As a result, they have been asked to use less water until Lake Victoria goes back to its old level.
Whether the low water level is caused by drought or power plants, the result is the same. This is already a poor area of Africa, where many people live a really hard life. People, animals and plants around Lake Victoria will suffer even more from low water levels on the lake. Many people need Lake Victoria for fishing or growing food. Fish need the water to live, and animals need it for water. Plants around the lake will die without the water, and then more animals and people will suffer. Unless the lake fills soon, many people will suffer and die.Lake Victoria is __________.
| A．an important lake in Africa |
| B．the largest lake in the world |
| C．the source of water, food and power for America |

B. There has been little rain in the lake area since 2000.

It was Mother’s Day. John was so busy with his work that he couldn’t go back home. When he walked by a flower shop in the evening, an idea came to his mind. “I’ll send Mum some roses (玫瑰).”
While John was picking his flowers, a young man went inside. “How many roses can I get for only five dollars, Madam?” he asked. The shop assistant told him that roses were as expensive as forty dollars a dozen (一打). Maybe he would be happy with carnations(康乃馨). She told him they were a lot cheaper than roses.
“No, I have to have red roses,” he said, “My mum was badly ill last year and I didn’t get to spend much time with her. Now I want to get something special, it has to be roses, as the rose is her favorite.”
After hearing this, John said he would pay the rest of the money for the young man. Moved by both of them, the shop assistant said, “Well, lovely young men, thirty dollars a dozen, only for you two.” Taking the roses, the young man almost jumped into the air. He thanked John, and ran out of the shop. It was well worth twenty-five dollars John paid to see the exciting moment. Then John paid for his dozen of roses and told the shop assistant to send them to his mother.
As he walked out, he felt nice. Suddenly he saw the young man crossing the street and going into a park. But soon he realized it was not a park but a cemetery (墓地).
