6.感官动词用法之一：see, hear, listen to, watch, notice等词，后接宾语，再接动词原形或ing形式。前者表全过程，后者表正在进行。句中有频率词时，以上的词也常跟动词原形。 I heard someone knocking at the door when I fell asleep. (我入睡时有人正敲门)

3.有时宾补后可接带to不定式 I found it hard to fool the girl.
4find后也有v-ing形式作宾语补足语。I found him reading a book just now.
9.would like / want / feel like: 1would like，和want类似：
◇都可接名词短语：I would like / want another three desks.

1It + take + sb + some time + to do sth： It took us half an hour to cut down the tree.

4人 + spend + 时间/ 钱 + on sth / (in) doing sth.

spend 有时可指“度过”：spend holiday / weekends / winter
13.双宾结构：pass / give / teach / offer / lend / send / sell / call / show / buy / ask / tell 等可加双宾结构。也就是接sb + sth. Pass me the book, please. He gave us some pens.
其中pass, give, offer, lend, send, sell, show等也可接sth + to sb. 如: lend the book to me.
buy, build等可接sth + for sb. My brother bought a dictionary for me.
另外，若sth是代词时，不用双宾结构。Please show it to me. 而不说show me it.
