阅读下面短文，在表格内的空白处填入合适的答案(每空格限填一词)
It seems that a family just isn't complete (完整的) without a pet. But if pets aren't suitable to a family's lifestyle or environment, they can quickly lead to problems such as stress or arguments (争执). To save yourself and your family such problems, treat this decision seriously.

When choosing a pet, people must consider the family's health. Many people are allergic (过敏的) to cats and dogs. Perhaps a dog or cat with short hair will be fine. And a dog might not be the best choice for a child who is naughty (顽皮的) because the dog might bite him or her. Some people can also have problems with certain pets. It's a good idea to spend a little time with the pet around each member of the family before making your decision.
Consider the quality of life of the pet, too. If a pet is used to having space to run around, it can quickly develop psychological (心理的) problems when it is kept in a small flat all day. If pets are allowed to run about in areas with lots of traffic, they can meet an early end. Cats shouldn't be brought into homes that already have large dogs because they won't be able to get along well with each other.
The decision as to what kind of pet to choose is very important. If you find the right one to suit (适合) everyone in the family and their lifestyle, then it's time to choose one. Remember that your decision is important because it can have effects that last for many years.

    Winter is very cold in many countries. It's easy for you and me to keep warm. If we are cold, we can just buy a warm coat or use a heater and we will feel better. But what about animals? How do they keep warm in winter?

    Some animals migrate(迁徙). This means they travel to places where the weather is warmer. Many birds leave before the winter starts. They fly in groups. If they fly together, the trip will be safer. They like to migrate to the same place every year. Do you know how they can find the same place？Scientists say that birds use the sun, the moon and stars to help them. Other animals like moose(麋鹿) also migrate. Fish and whales swim to warmer water.

    Some animals don't have to leave their homes. They hibernate(冬眠) in winter. They fall into a very deep sleep. The animals' temperature drops and their breathing slows down. Before the winter, these animals must eat much food. If they don't eat enough, they may die while they are hibernating.

    Many Chinese students are good at English grammar, but their spoken English is so poor that they are afraid to speak in class or have a talk with others. There may be some reasons for their problems with spoken English.

    First, they fail to express themselves clearly because of a limited(有限的)vocabulary. The useful way is to enlarge their vocabulary. However, you can still communicate with others with a limited vocabulary, if you are active. Others will understand you with the help of your body language.

    Second, they are worried about making mistakes. Because they are shy and nervous, sometimes they may make mistakes easily. Yet we should know what we aim at is FLUENCE(流利) not ACCURACY(精确) when speaking. So we should speak as quickly and well as we can, even though sometimes we may use a wrong word or tense(时态), but it doesn't matter because others will still understand you.

    The third reason is that they don't pay enough attention to listening to what others are saying. So while you are speaking, you can't find the suitable topic or words to say. You have one mouth but two ears! What you hear is necessary for you to start speaking.

    Fourth, most Chinese students are passive(被动的) language learners. They just sit there waiting for speaking chances, and don't actively look for chances to improve their spoken English. All they can get is to accept the fact that their English remains poor.

    “Practice makes perfect ".So please be active from now on, try to catch every chance to speak wherever you go.

USE IT or LOST IT? It is up to you.
