在主动语态中,使让动词make , have ,let和感官动词see , Look , watch , notice ,listen, hear , feel ,find后必省略to ,但在被动语态中必须加上to例:在教室里我们听见他唱了这首歌we heard him sing this songin theclassroom.he was heard to sing thissong by us in theclassroom.[9.强调句式的用法]由Its....that/who....构成，中间的关系词必须是that/who，没有其他词的可能性。....that/who....的强调句型只是为了强调某一成分，而不充当成分。所以它和It作形式主语，真正的主语从句后置的情况有所不同。请看以下2 个例子就很容易分辨出2者不同。eg:1. Itsnecessary that weshould learn english.主语从句2. Itsnot until he got offthe bus that he realized she was the daughterofheadmaster.强调句型因为强调句型中的Its....that/who....在句子中不充当任何成分。所以去掉后句子依然完整。去掉Its....that/who....后就成了until he got off the bus herealized shewas the daughter of headmaster去掉后句子则不完整。[10.if 和whether的区别]（1）if 和whether都可以引导宾语从句，常常可以互换，表示“是否”。如：I don’t know whether（=if）Ishould tell him.
