1.There is a computer on the _________(teacher) desk.

2. Fruits and vegetables are _________ (health) food, and they are good for you..

3. Remember: brush your _________ (tooth) every morning.

4. ________（they）favorite subject is science.

5.My mother _________ (not buy) any chocolate because it isn’t very healthy.

Answer 1

1.teacher’s

2.healthy

3.teeth

4.their

5.doesn’t buy

【解析】

1.teacher’s考查名词所有格。句意：老师的办公桌上有一台电脑。teacher是名词单数，变所有格时直接加’s。

2.2】healthy考查形容词。句意：水果和蔬菜是健康的食物，他们对你的身体有好处。空格后是名词，所以填形容词。healthy健康的。

3.3】teeth考查名词变复数。tooth, foot, goose变复数时，改为teeth,feet,geese。

4.4】their考查形容词性物主代词。句意：他们的最喜欢的学科是科学。空格后有名词，所以用形容词性物主代词。their他们的。

5.5】doesn’t buy考查否定句。实意动词play变否定时结构为 don’t或doesn’t + 动词原形。主语my mother是名词单数，所以用doesn’t + 动词原形。

考点：用动词的适当形式填空
