Business was poor, and the family barely scraped by.4．He decided to put the young man through university, paying everything for him to attend college, including tuition, books, and other living expenses.5．First, the young man should not tell anyone where he got the money; second, he must maintain top grades; third, he should pay back the money when he could afford to; and finally, he should promise to do the same for someone else in his life.6．He did quite well in the university. He earned high grades, was near the top of his class and was elected president of the student body.7.

(p.122.)Retirement brings people’s career to an end. They find, all of a sudden, that they can no more/longer carry on the job they have done for dozens of years. Some old people cannot adapt themselves to such a change and thus become depressed, believing that they are no longer useful. Indeed, depressions has become one of the leading threats to old people’s health. Nonetheless, many old people’s health. Nonetheless, many old people in China are able to maintain their sense of usefulness by rendering their grown-up children services, such as taking care of their grandchildren and providing allowances to them. The question remains as to whether senior citizens should try other means to fill up their leisure, rendering their later years still more meaningful. I suggest the old concern themselves less with their children and make room for young people to take responsibility for their own lives. After all, the old deserve respect from the young and the young should tolerate their aged parents more, on the grounds that the old have contributed so much for so many years both to their family and to society.Writing：Why Do Young Adults Kill ThemselvesYoung adults are in the prime of their lives are suppose to pursue their dreams and enjoy themselves. Yet itwas reported in the Guardian that suicide is the main cause of death among young adults in China, Why have so many young people ended their lives?Three factors are thought to account for the high suicide rate: increasing stress, loneliness and lack of medical support for depression. The most pressing one, I think, is stress. Take my college life for example. From the first day I entered the university, I have been living under pressure. I used to worry that I could not quite fit into the campus life; I also feared that I might not catch up with my classmates in my studies or could not live up to my parents’expectations. Now I am deeply concerned about whether I can find a desirable job after graduation. Endless pressures give rise to stress. Loneliness is another problem. Many young people find they just feel helpless when they are suffering intolerable sadness or frustration. Suicide is a great tragedy, especially for the young. If we can find ways to relieve them of their stress and offer timely help, we may save many young lives.。
