連詞
初中英語學(xué)習(xí)最難的是語法,因為英語的語法跟漢語的語法有很大的不同。初中英語連詞有很多種。下面為大家講解一下初中英語連詞的用法。
連詞是一種虛詞,它不能獨(dú)立擔(dān)任句子成分而只起連接詞與詞,短語與短語以及句與句的作用。連詞主要可分為兩類:并列連詞和從屬連詞。
第一類表示并列關(guān)系的連詞
并列連詞:并列連詞用來連接平行的詞、詞組和分句。
and 和
判斷改錯:
(錯) They sat down and talk about something.
(錯) They started to dance and sang.
(錯) I saw two men sitting behind and whisper there.
(對) They sat down and talked about something.
(對) They started to dance and sing.
(對)I saw two men sitting behind and whispering there.
解析:
第一句: and 連接兩個并列的謂語,所以 talk 應(yīng)改為 talked。
第二句:and 連接兩個并列的動詞不定式,第二個不定式往往省略to,因此sang 應(yīng)改為 sing。
第三句:and 連接感觀動詞saw 后面的用作的賓補(bǔ)的兩個并列分詞結(jié)構(gòu),因此whisper應(yīng)改為whispering。
注意:1. and 還可以和祈使句或名詞詞組連用表示條件。(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
