根据短文理解完成下列各题。
   March 16 is World Sleep Day. This year's slogan is “Breathe Easily, Sleep Well”. Its aim is to celebrate the *benefits of good and healthy sleep.
   Fangfang, from Liaoning, just became a high school student last September. She gets up at 5:30 a.m. every day and goes to bed at about midnight. Fangfang feels sleepy all the time. “I want to finish all my homework first,” she said.
   Sleep is like food for the brain. Enough sleep helps the body and brain grow and develop. According to the National Sleep *Foundation in the US, adults need seven to nine hours of sleep every night. For students who are 10 to 17 years old, a healthy amount is about eight to nine hours every night.
   But many students don't get enough sleep because of early school start time and heavy homework. About 80 percent of middle school students don't get enough sleep, the China Youth and Children Research Center reported. For some students, they want to sleep early, but they keep worrying about their schoolwork and can't fall asleep quickly. For others, they may even have insomnia, and usually they have to ask the doctors for help.
   These sleeping problems greatly *affect people's life. Some doctors found out that *lack of sleep for teenagers lead to poor grades. Students without enough sleep cannot pay attention in class or do well in sports. Also, they often become anxious easily.
   Luckily, with good sleep habits, it is easier to fall asleep. Some of these good habits include *avoiding drinks that make people excited late in the day, going to sleep at the same time every night, and sleeping in a comfortable place that is dark, quiet, and neither too warm nor too cold.
   More tips to get a good night's sleep:
   Exercising during the day. You'd better do sports three hours before going to bed.
   Don't eat big meals before bedtime. Drink a warm glass of milk. If you stay awake worrying about things, try making a list of things that you need to do before you go to bed.

You may have played Ant Forest. It is a game. Users collect "energy" to grow 1 "trees" online. Amazingly, when this "energy" reaches a certain level, real 2 are planted in deserts by some organizations and companies in China! It seems that our country's effort, along with India's, has made a 3 world.

4 by NASA in February showed that China and India have made the Earth greener over the past two years. Since 2000, the Earth's green leaf area has 5 by over 5 million square kilometers. That's as 6 as the Amazon rainforest! NASA said this is 7 due to big tree-planting programs in both countries.

"China and India cover only 9% of the planet's land area in vegetation (植被), 8 they did one third of the increased greening for the whole world," said Chi Chen, the study's lead author and a researcher at Boston University. China was the 9 contributor (贡献者), adding 25% of the increase, while India added 6.8%.

10 the past ten years, China has done a great job of greening the land. Since 1978, China has had a national forestation (植树造林) project 11 as the "Great Green Wall". Trees have been 12 in thirteen provinces in northern China to act as windbreaks (防风林).

With China's success in forestation, the United Nations Environment Program 13 China is a good example for others to follow. "China is one of the most 14 countries in greening the desert. It also has 15 to share with the world," said UNEP Executive Director Erik Solheim.

 阅读下列短文,根据短文内容从每小题所给的A、B、C、D四个选项中选出最佳答案。

① Animal behavior is an interesting and attractive study. Scientists research the ways animals use to look for food. They study how animals protect themselves from their predators, and which animals kill other animals for food. All of this helps us understand how useful animals can be.

② Each country or culture raises some animals for food. In the United States, people mainly eat meat from cows, chickens and pigs. In some other countries, people might raise sheep or buffalo for meat. These differences come in part from weather and other environmental conditions (状况). People around the world eat al kinds of fish and shellfish from oceans and rivers. In some countries, people don't always choose some animal groups, such as dogs, for food while in other countries such animals may become people's favorite food.

③ In West Africa, animals provide humans with more than food. They have been helping people do daily work for thousands of years. Horses, oxen, and other work animals pull heavy things. Elephants, camels and other animals carry people and things from place to place. Carrier pigeons (信鸽) have been used to send messages.

④ People also receive health benefits (利益) from animals. For example, dogs and cats can help calm people down. This is helpful for people fighting illnesses. Animals can also reduce stress, helping people to draw their attention to learning new information, such as reading. When people are walking their dogs or horses, it encourages exercise.

⑤ Animals and humans share space on Earth, so keeping a healthy relationship with animals around us is in our best interest.
