Don't believe ------he say.A what's B what words C whether D

/>Don't believe [ ___ he says.] 首先,【】中的从句放在谓语动词believe之后,作宾语,所以为宾语从句.从句中[he says---] 应该是he says sth,所以从句缺宾语,选用what .宾语从句,缺成分事,常选用三个代词 what（指物,充当主语,宾语）,who指人,做主语,whom指人,做宾语.

英语中一个句子在没有连词的情况下,不能有两个谓语动词.原句Paui 是主语,谓语动词是made （make的过去式）,再出现第二个动词只能用非谓语,非谓语有三个,to do表目的,ving 表主动,Ved表被动.这题意思PaUI做了一个好的笼子为的是养这只生病的小鸟直到它能飞,所以to keep 表目的.
