一、非谓语动词

“非谓语动词”可分为动词不定式、动名词和分词.它在句子中的作用很多：除了不作谓语外,它可以充当主语、宾语、表语、定语、状语与复合宾语(主语补语或宾语补语).有些及物动词后面接不带to的不定式作复合宾语.这些动词归纳如下：一感(feel).二听(hear,listen to),三让(have,1et, make),四看(see,watCh,notice,observe).再加上help somebody(to)do something和美国英语look at somebody do somthing.还有“二让”属特殊：get somebody to do something 与keep somebody doing.而有些及物动词后面接动名词(the -ing form)作宾语.这些动词归纳为一句话：Papa C makes friends.这是由如下动词的开头字母组成：permit,advise, practise,avoid,consider,mind, allow,keep,enjoy,suggest, finish,risk,imagine,escape,need,delay,stand(忍受). 为了容易记住,也可以编成顺口溜：“允许完成练习,建议避免冒险,考虑延期逃跑,喜欢保持想象,需要反对忍受”.其相对应的动词依次是：permit/allow,finish,practise;

advise/suggest, avoid,risk： consider, delay, escape/miss; enjoy/appreciate, keep, imagine; need/want/require,mind. can't help/can’t stand.

look up the dictionary

汉语中的“查字典”，说成英语通常是 look up sth in a dictionary 或 consult [refer to] a dictionary。如：

I refer to the dictionary frequently. 我经常查阅词典。

You can look the word up in the dictionary. 你可以在词典里查这个词。

He often consulted a dictionary when he read the book. 他读这本书时经常查字典。

I looked the word up in the dictionary to refresh my memory of its exact meaning. 我查了词典，以便弄清这个词的准确意思。

I often look up the words I don’t know in the dictionary or on the Internet. 我经常在字典里或网上查找我不认识的单词。

“Is that the correct spelling?” “I don’t know—look it up in a dictionary.” “那是正确的拼写吗?”“我不知道——查查词典吧。”

I didn’t know what “loquacious” meant and had to look it up in a dictionary. 我不知道loquacious这个是什么意思，所以只好查了词典。

有不少人认为英语习惯上不能直接说 look up the dictionary, 其实这种表达在英语中也可以用，只是比较少见而已。例如：

I spend more time looking up the dictionary than reading the book. 我读这本书时查字典的时间还多些。——摘自 L. G. Alexander 编《新概念英语》(外研社)

Look up the dictionary and explain the meaning of the italicized words. 查字典然后解释斜体词的意思。——摘自张汉熙编《高级英语》(商务印书馆)
