When Mark left school, he did not really know what he wanted to do. He 36  worked in an office but he found that it was very boring. He did the   37  things day after day. This was also the trouble with his second   38  in a car factory. He then decided he would like to work out of doors and got a job  39  a gardener working in one of London’s    40 .
He now works much harder than he   41  in the office or at the factory, but his work is quite different. There are, in all,   42  seasons in a year and each has its own special jobs for a   43  . He works harder in the autumn and winter keeping the park tidy and   44  for the spring and summer. In the summer he can relax(休息) and feel proud(自豪的) that he has helped to   45  the park so beautiful. Many people   46  the park then and he is always pleased   47  he hears them say how lovely it looks.
Mark has made a lot of friends during his four   48  at the park. Many office workers come every  49 to eat their lunchtime sandwiches and feed the ducks. They often have talks with him and are  50  to find that he once worked in an office.

When are you an adult (成年人)？
When do you think you are an adult ? Maybe different __31_ have different ideas.
Now let’s see what some American teenagers(青少年)say .
Sam: In  32 idea ,you are an adult at the  33  of 18. That’s when you can vote(投票)。You can help to   34  who rules(統(tǒng)治)the whole country .That’s also a grown-up does! My grandfather couldn’ t vote   35 he was 21.They changed（改變） it to 18 in 1971.
Jenny：I don’t 36  it’s hard to say . I can drive a car at 16, can’t I ?When you have a driver’s licence , you can 37 it to people to tell them your age for all kinds of things .  38    sixteen must be the age when you change from a  39  person to an adult.Because you can tell others you are not a  40   any more .
Suzie : Well , I think there is  41   wrong with American laws for when young people can  42  things . I can vote at 18 and drive at 16. So you would think 18 is a grown-up,  43  16 isn’t .But then I can’t drink wine（酒）until I’m 21 ! If I’m 44   an adult at 18, how can people stop me from  45   a cup of beer in a bar ?

When I was a kid, I liked summer best. 36 ?  Because I could do what I like. I could go 37 at the pool. I could 38 my beautiful skirts. And of course there 39 no school. But autumn (秋天) is my 40 season now.
Summer is too hot, so I always 41 in the house. I 42 like it. Winter is usually too 43 . I don’t like to go outside and I have to wear lots of warm clothes. In spring (春天) it usually rains. It’s my second favorite season.
Autumn is the best. It isn’t too hot 44 too cold. The temperature (溫度) is 45 18℃and 22℃. It’s a great time of the year. I like it.
