[误]:A number of exchange students is visiting the museum.
[正]:A number of exchange students are visiting the museum.
A number of……意为“大量，许多”，后跟复数动词。 the number of…..意为“……的数目”，后跟单数动词。又如：
The number of the workers in this factory is about 500.
[误]: The United States are a developed country.
[正]:The United States is a developed country.
the United States,physics,politics,maths等名词形式是复数，但是表示单数意思，后跟单数动词，注意 police,people形单意复，后跟复数动词。The police are searching for the robbers.
[误]: This pair of jeans are very expensive.
[正]:This pair of jeans is very expensive.
glasses,trousers,jeans,scissors,gloves 等由两部分组成的名词作主语，后用复数动词，但如有pair修饰，则谓语动词与pair的单复数相一致。
[误]:The black and white sheep are eating grass at the foot of the hill.
[正]:The black and white sheep is eating grass at the foot of the hill.
and连接名词或代词作主语，动词常用复数。但如指同一个人或物，动词用单数。试比较：The black and the white sheep are eating grass at the foot of the hill.
[误]: There are a teacher and forty students in the classroom.
[正]: There is a teacher and forty students in the classroom.
There be 结构中be的单复数取决于其后的主语，但如是并列主语要求与就近的主语相一致。
十三、非谓语动词
[误]: Let one of the students reads the text.
[正]:Let one of the students read the text.
read the text 在句中作one of the students的宾语补足语。结构为 let sb do sth. 类似的还有make sb do sth（使某人做某事）, have sb do sth.（让某人做某事） hear(see)sb do sth.（听见或看见某人做某事）。
(1)要求用to do作宾语的常见的有:want to do; hope to do;decide to do;plan to do;wish to do; try to do; fail to do; would like to do.(2) 要求用to do作宾语补足语的有:want sb to do;encourage sb to do;ask sb to do ;tell sb to do; order sb to do; allow sb. to do(3)用不带的to不定式常见的有 had better do sth;Will(would)you please do sth;Why not do sth.(4)be happy(sorry,surprised,excited…) to do ;
要求用v-ing的结构有have fun doing ; be busy doing; have some problems doing ; be good at doing;be worth doing; be used for doing ; allow doing ; keep(sb) doing; finish doing; like doing; enjoy doing; practise doing; mind doing; give up doing; prefer doing to doing; sb spends some time doing ;
[误]: Tell him don’t to forget to turn off the light.
[正]: Tell him not to forget to turn off the light.
否定不定式，在不定式前加not即可。
[误]: He was so tired that he stopped having a rest.
[正]: He was so tired that he stopped to have a rest.
stop to do sth.停下来去做某事 stop doing sth.停止做某事；区别 forget(remember) to do sth.忘记或记住做某事forget(remember)doing sth,忘记或觉得做过某事。
[误]: The cakes making by my mother taste very delicious.
[正]: The cakes made by my mother taste very delicious.
v-ing作定语有主动进行的含义，而v-ed(过去分词)作定语有被动完成的含义。
[误]: We found that important to take enough exercise every day.
[正]: We found it important to take enough exercise every day.
it常用来代替动词不定式在句中作形式主语或形式宾语。
十四、被动语态
[误]: The students today are made do much homework every day.
[正]: The students today are made to do much homework every day.
主动结构中用不带to不定式（即动词原形）作宾语补足语的在被动语态中要求加上to常见有be made (heard,seen)to do sth.
[误]: This story was happened in a small village.
[正]:This story happened in a small village.
happen为不及物动词，不及物动词不能用于被动语态。
[误]: The old must be spoken politely.
[正]: The old must be spoken to politely.
被动语态中，句子的主语是谓语动词动作的承受者，逻辑上作动词的宾语，故帮助构成及物动词的介词或副词不能少。
[误]: This kind of object is felt smooth.
[正]: This kind of object feels smooth.
feel”感觉”,连系动词，没有被动语态。
十五、介词
[误]: The car accident happened in the night of February 10th.
[正]: The car accident happened on the night of February 10th.
介词on用于“具体某天”前，in用在“年，月，季节”前.
[误]: The students often chat with each other with English.
[正]: The students often chat with each other in English.
介词in, by with都可表示“用”；in“用语言或方式”；by 用“手段”；with.“用工具”又如：People in the west celebrate the Halloween in different ways.
People in China eat with chopsticks.
Please teach us how to send messages by telegraph.
[误]: I don’t know the answer of your question.
[正]: I don’t know the answer to your question.
“……的”用of ;但the entrance to…… “……的入口”;the ticket for.“……的票”;the key to….”……的钥匙”。
[误]: Everyone is looking forward to visit the Summer Palace.
[正]:Everyone is looking forward to visiting the Summer Palace.
look forward to中to为介词，介词后用名词或动名词。又如：make a contribution to doing sth.（对做…作出贡献） be used to doing sth.（习惯做某事）。
