Question

20．阅读一本书之前，最好仔细阅读下它的书名和作者简介．（had better）You had better read carefully its name and the author's introduction before reading a book．．

Answer 1

分析 阅读一本书之前，最好仔细阅读下它的书名和作者简介．

解答 答案：You had better read carefully its name and the author's introduction before reading a book．考查had better的用法．
句子里had better do表示"最好做某事"；the author's introduction表示"作者简介"； reading a book是现在分词做时间状语．

点评 考查汉译英．
had better 是 最好 的意思
这两个词组合在一起当做情态动词，也就是后面直接加动词原形，否定式在better后加not，再加动词原形．
eg（举个例子）：
1．You had better go out for a walk．（你最好出去走走）
2．You had better go out．你最好不要出去
注意，You had better 可以写为 You'd better
