It’s important to brush your _________ twice a day.

A. tooth   B. tooths      C. teeth

 

【答案】

C

【解析】

試題分析：根據(jù)語境可知此句的基本含義是每天刷兩次牙是非常重要的，刷牙要用復數(shù)形式，故選C。

考點：名詞的復數(shù)形式

點評：英語中，可數(shù)名詞的單數(shù)轉(zhuǎn)換為復數(shù)形式有一定的規(guī)則，有的在詞尾直接加s或es；也有的是不規(guī)則變化，比如man的復數(shù)形式是men，child的復數(shù)形式是children。對于這些不規(guī)則變化的單詞的復數(shù)形式一定要記清楚。

閱讀下列短文,根據(jù)短文中的信息完成文后表格。在標有題號的橫線上，寫出空缺處所填單詞的正確形式。（每空一詞）

There are many things you can do to improve your memo­ry. Among them are many kinds of useful ways as well as taking special care of your health.

It is important that you make yourself excited to make your memory more active. You can do this by doing some new activi­ties and by changing your daily habits. Learning a new skill helps your brain(大腦)to develop. When trying to remember something, you should pay special attention to the most impor­tant things about it. Do not allow other thoughts to enter your mind because this will reduce your chances of making right memories.

An excellent way to help memory is to connect information with pictures. Try to see the pictures in your mind. Taking notes and keeping a diary will also be helpful.

Healthy food and plenty of vitamins are necessary for your memory to work well. Drinking a lot of water also helps keep your memory. You must allow your brain to have enough sleep and rest. When you are asleep ， your brain stores memory. Not enough sleep can cause problems with storing information. And being tired will also stop you from being able to think clearly and well.

In order to keep your mind on your work ， you must be free from worry. Generally, keeping fit and normal health checks are both important as well — not just for improving your memory.
