81. I, who is your friend, can understand you.定语从句的谓语动词应与其先行词保持一致，因此把is 改为am。

　　82. China is a developing country, that is known to all.非限定性定语从句的引导词永远不会是that，因此把that 改为which 或as。

　　14

　　主谓一致

　　83. The poet and writer are invited to give a speech at the meeting.poet和writer共用一个冠词，指的是一个人身兼二职，所以谓语动词应为单数。把are改为is.

　　84. No one except my parents know it.主语后加except再加上若干数量的名词，谓语动词和主语保持一致。所以把know改为knows。类似的用法的词或短语有：but, besides, with, together with, along with, as well as等等。

　　85. Your clothes is on the table over there.clothes为复数名词，谓语动词应为复数。把is改为are。

　　86. The number of the students in that school are about one thousand.此句的主语为number而不是students。因此把are 改为is。

　　87. The class was watching TV when I entered the room.class作主语时，把它看成一个整体时谓语动词用单数，看成每一个成员的个体行为时谓语动词用复数。一般来说，一些具体行为如看电视、吃饭、洗澡等都属于每一个成员的个体行为。此处把was改为were。

　　88. The population of our country are increasing slowly now.population 单独作主语谓语动词经常用单数;如果其前有分数或百分数，而且后面又有复数名词时谓语动词用复数。如：One fifth of the Chinese population are workers. 此处把are改为is。

　　15

　　倒装

　　89. No sooner he had reached the station than the train left.no sooner 为否定副词，放于句首时句子要部分倒装，因此此句应改为：No sooner had he reached the station than the train left.

　　90. Here comes he.here 放于句首时，句子主谓要完全倒装，但句子主语为代词时，则主谓不倒装。此句应改为：Here he comes.

　　91. A child as he is, he can speak five languages.用as引导让步状语从句，可把形容词、副词和不带冠词的名词放于as前。所以前半句改为：Child as he is...

　　16

　　虚拟语气

　　92. She would have come if we invited her.这是与过去事实相反的虚拟假设，从句应该用过去完成时。所以在 we 后加 had。

　　93.My suggestion is that we would send a few people to help them.suggestion 的表语从句也应用虚拟语气，必须用should加动词原形，should可以省略。此处去掉would 或把would 改为should。

　　94.The secretary wishes that she has time to type the letter now.wish 后的时态应该把真实时态往后推一个时态，所以把has改为had。

　　95.It’s time that we go to bed.句式为It’s time sb did sth.， 所以把 go 改为 went。

　　96.I would rather you have another try tomorrow.句式为would rather sb did sth. 所以把have改为had。

　　17

　　There Be句型

　　97. There are a bag and several books on the table.There be 句式遵循谓语动词就近原则，a bag为单数，所以把are改为is。

　　98. There were several people stood at the back of the room.There be句式的谓语动词为be动词，句中其他的动词应为非谓语动词。所以把stood改为standing。

　　18

　　修饰语在居中的位置不当

　　99. We almost have written twenty compositions this term.像almost这样的副词在句中放在助动词、be动词之后，实意动词之前。因此把almost放在have后面。

　　100. The girl has beautiful, silky hair who lives high in the mountains.定语从句应紧跟先行词，所以改为：The girl, who lives high in the mountains, has beautiful, silky hair.
