题目内容
15.We all know you are smart,but you'd betternot show(not show) off.分析 我们都知道你聪明,但是你最好不要炫耀.
解答 答案:not show.结合句子的结构you'd是you had 的缩写,had better do sth表示最好做某事,否定句是had better not do sth,故答案是not show.
点评 had better后跟动词原形(即不带to的不定式),构成had better do sth.句型. 这里的had不能用have来替换.如:
You'd better go to hospital at once.你最好立即去医院看病.
Tom,you'd better go there today.汤姆,你最好今天去那儿.
主语不论是第几人称,句子不论是什么时态,都要用had better的形式.如:
Now you(he,we) had better listen to the teacher.你(他,我们)现在最好听老师讲.
