【篇一】2020年上半年大学英语六级基础语法知识

　　1)下列动词：come, go, arrive, leave, start, begin, return的一般现在时表将来。这主要用来表示在时间上已确定或安排好的事情。

　　The train leaves at six tomorrow morning.

　　When does the bus star? It stars in ten minutes.

　　2)倒装句，表示动作正在进行，如：

　　Here comes the bus. = The bus is coming.

　　There goes the bell. = The bell is ringing.

　　3)在时间或条件句中。

　　When Bill comes (不是will come), ask him to wait for me.

　　I‘ll write to you as soon as I arrive there.

　　4)在动词hope, take care that, make sure that等后。

　　I hope they have a nice time next week.

　　Make sure that the windows are closed before you leave the room.

【篇二】2020年上半年大学英语六级基础语法知识

　　并列连词引导两个并列的句子。

　　1)　and 与or

　　判断改错：

　　(错) They sat down and talk about something.

　　(错) They started to dance and sang.

　　(错) I saw two men sitting behind and whisper there.

　　(对) They sat down and talked about something.

　　(对) They started to dance and sing.

　　(对)I saw two men sitting behind and whispering there.

　　解析：

　　第一句： and 连接两个并列的谓语，所以 talk 应改为 talked。

　　第二句：and 连接两个并列的动词不定式，第二个不定式往往省略to，因此sang 应改为 sing。

　　第三句：and 连接感观动词saw 后面的用作的宾补的两个并列分词结构，因此whisper应改为whispering。

　　注意：and 还可以和祈使句或名词词组连用表示条件。(or也有此用法)

　　Make up your mind, and you‘ll get the chance.

　　= If you make up your mind, you‘ll get the chance.

　　One more effort, and you‘ll succeed.

　　= If you make one more effort, you‘ll succeed.

　　2)　both …and　两者都

　　She plays (both) the piano and the guitar.

　　3)　not only…but (also), as well as不但…而且)

　　She plays not only the piano, but (also) the guitar.

　　注意： not only… but also 关联两个分句时，一个分句因有否定词not 而必须倒装。

　　Not only does he like reading stories, but also he can even write some.

　　4)　neithe…nor 意思为"既不……也不……"谓语动词采用就近原则，与nor后的词保持一致。

　　Neither you nor he is to blame.

【篇三】2020年上半年大学英语六级基础语法知识

　　had better 相当于一个助动词，它只有一种形式，它后面要跟动词原形。

　　had better do sth

　　had better not do sth

　　It is pretty cold. You‘d better put on my coat.

　　She‘d better not play with the dog.

　　had better have done sth表示与事实相反的结果，意为"本来"。

　　You had better have come earlier.
