不过，在使用英语不可数名词时，又会出现两种情况，一种是绝不可以用a/an或数词来直接修饰，如上述提及的几个名词：另一种情况是，少数不可数名词在被形容词等修饰后，可用a/an等来修饰。如time(时间)，rain(雨)。所以我们可以说：We had a wonderful time yesterday. 例如：

a. The air is the most important thing for our existence.

b. The driver brought the car to stop. In this way, he avoided an accident.

c. When sun was setting, he still did not catch any fish.

正确的句子：

a. Air is the most important thing for our existence.

b. The driver brought the car to a stop. In this way, he avoided an accident.

c. When the sun was setting, he still did not catch any fish.

7、代词的错误

代词主要有人称代词、物主代词、关系代词、反身代词、疑问代词、复合疑问代词、指示代词，要注意代词的各人称之间和单复数之间的误用，关系代词 which, that, as之间的误用，关系代词that与疑问代词what之间的误用，关系代词which与关系副词when, where，以及what与how的误用等。例如：

a. We do not like he.

b. If you like this books, you can take them away.

c. His book is different from me.

d. The population of China is larger than those of Japan.

正确的句子：

a. We do not like him.

b. If you like these books, you can take them away.

c. His book is different from mine.

d. The population of China is larger than that of Japan.

汉语里，人称代词没有主格、宾格和所有格之变，而英语中的人称代词有主格、宾格和所有格之变，而且每格都具有其自身的用途，分别充当主语、宾语和定语等。尤其要注意的是，人称代词充当介词宾语时，也要采用其宾格形式。

8、连词的错误

连词主要有两类，即并列连词和从属连词，考查点主要是并列连词(分递进式、转折式、选择式和因果式四种)之间的误用(主要是but与so/and之间的误用)，从属连词之间的误用以及并列连词与从属连词之间的误用等。例如：

a. He had little to eat and a large house to live in.

b. He had no sooner arrived when he fell ill.

c. If you go this way, and you will soon see the hospital.

正确的句子：

a. He had little to eat but a large house to live in.

b. He had no sooner arrived than he fell ill.

c.1f you go this way，you will soon see the hospital.

9、名词的错误

名词主要考查单数名词变复数名词，这主要是受东西方文化差异的影响，英语中除了不可数名词和单数名词用单数外，可数名词要用复数形式。另外还有一些特殊形式。例如：

a. What a beautiful weather we are having today!

b. Please give my best regard to your parents.

c. I have got good marks in all my subject.

正确的句子：

a. What beautiful weather we are having today!

b. Please give my best regards to your parents.

c. I have got good marks in all my subjects.

10、情态动词和助动词的错误

这类错误有以下几种情况：① 情态动词后的动词使用过去时态;② 情态动词后的动词加“s”③ 情态动词后的动词加“ing”④”will”后面的“be”动词用“am、“is”或“are ”;⑤助动词“do”后面的动词用动词过去时态;⑥。助动词“do”后面的动词第三人称单数加“s";⑦ 助动词“do”后面的动词加“ing”等。例如：

a. I could did my homework.

b. He may goes to school by bike every day.

正确的句子：

a. I could do my homework.

b. He may go to school by bike every day.
