【推荐2】请阅读下面短文,从每小题所给的A、B、C三个选项中,选出一个最佳选项,并在答题卡上将该项涂黑。
Years ago, if a teenager had some problems in his life, he might write them in his diary. Now a teenager might surf the Internet and write them in his blog (博客). In some ways, a diary and a blog are the same. What makes a blog different from a diary?
The biggest difference is that a blog is much more public (公开的) than a diary. I have a younger sister, and sometimes I read her blog. She writes about things like getting up early for swimming practice and not studying enough for her chemistry exam. When I was her age, I wrote the same things, but only in my diary. After I finished writing, I would put my diary in a secret place because I was worried that someone else might read it.
A blog is public so it has some bad points (特点). The biggest problem is that anyone can read what you write. If I am angry with a friend at school and write something bad about him in my diary, he will never know. However, if my sister writes something bad about a friend, her friend may read her blog and cry. So we must be very careful about what to write.
Blogs have good points, of course. If I feel lonely and write “Nobody cares about me.” in my diary, no one will know about it. However, if my sister writes the same words in her blog, her friends will quickly reply and tell her how much they like her. A blog helps people keep in contact (联系) with their friends.
If people are careful, writing blogs is really a good way to communicate with others. However, I still enjoy my diary!

【推荐3】Do you know that the falcon (猎鹰) is among the fastest animals in the world? It can fly at a speed of about 200 miles per hour. You might think a bird that could fly so fast would be safe from most types of danger. Unfortunately, that is not true. By the 1970s, they had already been endangered. What was causing the number of falcons to drop so quickly?
In America, a pesticide, a chemical, called DDT was harming the falcon eggs. Luckily, DDT is no longer used. The number of falcons is rising now.
One unusual thing about falcons is that they like to make their nests (巢) in high places. In nature, they often nest on mountaintops and on the sides of cliffs (悬崖). Falcons have also got used to life in cities. They nest on tall buildings and bridges in cities. The height of these nests is from 50 to 200 feet in the air.
They also like to return to the same nesting place every year. Both the mother and father falcons help to raise the babies. The mother stays more time in the nest. The father hunts and brings back food for her and the babies.
Many people all around the country work very hard to help falcons live to adulthood. There are even video cameras fixed up in many places. This way, people can make sure the birds and their eggs stay protected. Falcons are lucky to have so many people who keep an eye on them.
