上面每组A、B两句的划线部分在句 中所充当的成分是一样的。 1. 第1组B句的V-ing形式在句中充当 宾语。除like外,我们还学过hate,


2. 第2组B句的V-ing形式在句中

B. Washing your hands before meals
is a good habit.

2. A. Do some sports every morning.
B. Doing some sports is good for your


以上两组例句中A、B两句划线部分的 意思相同,但形式不同。A句动词用原 形,B句动词用现在分词。A句是表示 请求、 命令等语气。B句是由动词现 在分词V-ing 形式开头作主语。A、B 两句最本质的区别是:A句为祈使句, 没有主语;B句有主语。

根据句意用所给单词的适当形式填空。 1. _____ (bring) your dictionary to Bring school tomorrow, please.

2. _______ (get) up early is difficult Getting

3. should和must的区别 情态动词should与must均可意为 “应该、必须”。请仔细观察下面 的例句,想一想should与must在用 法上有什么区别。

情态动词should常用于劝告别人最好 做某事,口气比较温和;情态动词 must常用于告诫别人必须做某事, 口气比较强硬。

根据上面得出的结论,将下面的句子翻译 成英语。 1. 你明天必须早点来这里,我有重要的事 想告诉你。 You must come here early tomorrow. I have something important to tell you. 2. 太晚了,你应该回家了。 It’s too late. You should go home.
