—Yes, I _________ lots of time on it. It's a good way to kill time.

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. If you 3 a tree, you can see that it has many rings. Most trees grow one new ring 4 year. Because of that, 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.

—You'd better not. It's bad for you _________ too much junk food.

We often face the following situations in our daily life：

●The woman next door plays her piano after 12 o'clock at night.

●The family across the street never cleans up their yard.The rubbish blows into your yard.

●The man next door always parks his car in front of your drive.

Have things like this ever happened to you? If so, you may ask yourself, "Who are these people? Why are they doing these things to me？"

These days, many people don't know their neighbors. Sometimes we share a friendly smile or say hello, but lots of people don't even know their neighbor's names! When you don't know someone, it's easy to be angry when something has happened that you think is unfair. You think, "Maybe they like to make me angry, " or "Maybe they do it on purpose." Believe it or not, your neighbors probably don't mean to irritate(激怒)you. Often, they don't even know that they're making you feel angry. So before you take unusual steps to fix the problem, you should discuss it with them first.

When you move towards your neighbors, you should talk to them in a friendly manner.Praise their children to make them feel good. Then explain the situation. And if you can think of a simple way to solve the problem, suggest it.

If talking doesn't work, ask another person to help. This person can listen to both sides of the story and help you and your neighbor solve the situation.

Finally, sometimes it's a good idea to avoid the problem. Depending on the problem, it might be best to just stay out of your neighbor's way.
