We know that trees are useful in our everyday life. They   1  us many things, such as wood, oxygen, rubber, medicines and many other things. They can  2  tell us a lot about our climate. The following are the reasons. If you   3  a tree, you can see that it has many rings. Most trees grow one new ring   4  year. Because of the reason, we know   5  a tree is. A tree over a hundred years old means that it has more than a hundred   6 . When the climate is dry or very cold, the trees do not grow very much and their rings are usually   7 . When it is wet and warm, the rings are much thicker. If the rings are suddenly very thin or suddenly very thick, this means that the   8  changed suddenly. If we look at the rings on this tree, we can learn about the   9  for a hundred years. We can see  10  our climate is changing today.

“Well, we're in our new house. Let's get a new pet to get along with it,” Mrs. Brown said to her husband.” That sounds like a pretty good idea,” he answered. “Do you want to see the ads in the newspaper？” “No. Let's go to the animal shelter. Many pets there need homes. Since tomorrow is Saturday, we can both go,” she said.

The next morning the Browns met Mr Snow at the animal shelter. “We want to be sure that the pets here go to good homes,” Mr Snow said, “So I need to ask you some questions.”

After they talked for a while, the Browns decided to get a small dog. It wouldn't need a big house or a big yard. A small dog would bark（吠）and warn them if someone tried to break into their house. After Mr Snow gave the Browns a book on pet care, they chose one and wanted to take her home right away. But the animal doctor hadn't checked her yet. So Mr Snow told them to return on Sunday.

On Sunday afternoon the Browns went to the animal shelter. The animal doctor said, “Shadow has had all of her shots(预防针). She will be healthy.” The browns thanked the doctor and took Shadow home.

What do you do if you're stranded（处于困境的）on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.
　　Body signals（信号）
　　Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend（弯曲）your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.
　　Smoke signals
　　The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.
　　Ground-to-air signals
　　It's a good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you can't find any wood, use earth. Some useful symbols are:
　　F "I need food and water."
　　II "I need medicine."
　　I "I am badly hurt."
　　X" I am unable to move from here."
　　Pilots' replies
　　If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)
However, there is no signal which means "message not received". Why not?
【小题1】 Which picture means "it's not safe land"?

　
【小题2】 What can we learn from the passage?

The Guidance Department （教导处）at Berryville High School has a staff of eleven teachers. Most of their work is done with the students. But the staff sees a lot of parents, too.

“Parents meetings make clear monthly diagram（图表）.”says Mildred Freman, head of the Guidance. “This diagram stays much the same from year to year. The busy months are October, March and May. ”

September, the beginning of a new school year, starts rather slowly. Few parents come in. Most of these want to talk about the schedules. October brings many problems caused by some students. Some parents are called in. Others come by themselves. Things quiet down in November. December is a quiet month. “It’s the holiday. ”Ms Foreman says, “People want to come in, I know, but they decide to wait until after New Year’s Day.”

Report cards go home just before Christmas holidays. Bad marks bring parents in as school opens again. This happens again in March, another report card month. May is always the year’s busiest month. That’s when parents begin to think that their children may be asked to stay in the same grade again. They come in to see if anything can be done before things are decided in June.

2.In December parents usually ______.

3.Why do some parents come to school in March? Because ______.
