When an important holiday comes, I usually think of what gifts to buy or prepare for my family members. It is the act    1    (it)rather than the things you buy that matters. Either a small present, a text message or a phone call can mean a lot to the receivers.    2    , I had never got anything from my son, who is    3    university student. Parents never forget to celebrate their children's birthday, but their children seem to be very forgetful. They seldom do something in return.

Life is unpredictable, and you never know what will happen tomorrow. When my son came back during the summer vacation, my wife and I, as usual,    4    (meet)him at the station. On arriving home, much    5    my surprise, my son took out a fashionable wrist watch and gave it to me,    6    (say)it was a birthday gift for me. You can imagine how    7    (surprise)and excited I was at that moment!

Some people say children get too much care and love from their parents,    8    they never express thanks for. It is natural for people to have such concerns and    9    (worry), but things may not turn out as badly as    10    (expect).

Some people thought Jia Sixie was     1     lucky man. He had worked for the emperor and when he got old, he could go to     2     (he) hometown to relax. Jia Sixie, however, had other plans. He had always been interested     3     agriculture and wanted to do something to make Chinese farming even better.

Jia Sixie     4     (live) about 1,600 years ago. He was born in Yidu in Shandong Province and worked in Gaoyang,     5     is also in Shandong. As he rode through the countryside, he looked out at the fields. Some of them were greener and had     6     (many) crops than others. Some     7     (cow) looked healthier than others too. He was lost in thought. What could a     8     (farm) do to get good crops from his field? Surely there must be rules that would help them. He thought he was able     9     (find) out the best way for farmers. Then he wrote a book     10     (call) Qi Min Yao Shu to help them.

Yuan Longping was born    1    1930. He graduated from college in 1953. Then he worked as a    2    (teach) at an agricultural school. From then on, he tried his best to find ways to grow more rice. After years of research, he    3    (final) made it. In 1973, he became the first person in the world to grow rice with a high output (产量). Thanks to his research, farmers are producing harvests twice    4    (large) than before. Although he is one of China's most famous scientists, Yuan Longping considers himself as    5    farmer, for he works the land to do his research.

Yuan Longping feels that being famous gives him less freedom to do    6    (he)research. So he doesn't care about it. He prefers keeping time for his hobbies. He enjoys    7    (listen) to music, swimming and reading in his spare time. Now he is more than eighty    8    (year) old and he    9    (be) satisfied with his life.

Such is Yuan Longping, a simple man    10    has great achievements.
