How to Deal With Mental Problems(如何处理心理健康问题)?
Mr. Ma, a famous mental doctor from Beijing once said in an important meeting, “Now many young students can have problems with their minds. Some students become worried because they have to study very hard. Others have trouble getting on well with people around them like their parents and classmates. Parents and teachers should care more about this problem.”
Then Mr. Ma gave some examples. One patient, a middle school student from Xi'an, was doing badly in his lessons. He thought his teachers and friends often laughed at him, and he became so nervous and worried that one night he left his home without telling his parents. Another student, a 14-year-old schoolgirl from Shanghai, was very afraid of exams. While she was reading the exam paper, she couldn't think of anything to write.
A recent report from Jiefang Daily says about 18% of the young students in Shanghai have mental problems. They often feel very worried and unhappy. Unluckily, many of them won't go and ask for help. Some think they will look stupid if they go to see a doctor. Others won't talk about their secrets.
At the end of the meeting, Mr. Ma offered some good ideas to young people：
·Talk to your parents or teachers often.
·Take part in group activities.
·Try to get on well with the people around you.
·Go to see a doctor if you often feel unhappy.

Save Food and Eat Healthily
Now the government has called on us to save food and eat healthily so that we can enjoy a happy life. We should do something for it.
To save food, we shouldn't waste any of our food. We should eat up all the food. We shouldn't order more food than we can eat while dining out, because many people in the world don't have enough food to eat. To eat healthily, we shouldn't eat junk food. It's good for us to have a balanced diet. We'd better not eat in small restaurants, because the food and the oil they use are probably not clean or healthy enough. We'd better eat at school or at home if we have time.

3．need作实义动词时，意为“需要，必需”，有人称和数的变化，可直接跟名词或代词作宾语。need to do sth.意为“需要做某事”； sth. needs doing相当于sth. needs to be done，意为“某事需要被做”。
