2018年上海中考英语复习系列五(重点介词和连词)(5)
4) 引导条件状语从句,常用的有:if,unless(除非),as long as(只要)等。例如: We will come here if it is fine tomorrow. 如果明天天气好的话我们就来这里。 5) 引导让步状语从句,常用的有:though,although,even if(即使),however(无论怎样)等。 例如:
We were still working though it was very late. 尽管很晚了我们仍然在工作。 6) 引导比较状语从句,常用的有:as,than,so/ as?as,more than。例如: This book is more interesting than that one. 这本书比那本更有兴趣。 7) 引导地点状语从句,常用的有:where, wherever等。例如: Please stay where you are. 请呆在你现在的地方。
8) 引导名词性从句(如宾语从句),,常用的有:that,if,whether,who,whom,what,which,
whose,when,where,why,how。例如:
Can you tell me when they got there? 你能告诉我他们是什么时候到那里的吗? I think that he’ll be back soon. 我认为他们不久就会回来。
连词使用时的几个注意事项:
1)not only? but also?, neither? nor ?, either ? or?, not ? but?接主语时,谓语动词按就近原则处理。
Not only you but also he has to leave. 不只是你,他也得离开。 Either you or I am wrong. 不是你错,就是我错。
Not money but workers are what we need. 我们需要的不是钱,而是工人。
2)祈使句,+and/ or +简单句,前面的祈使句表示条件,后面的简单句表示结果,or意思为“否则”。
Hurry up, and we’ll catch the bus. 快点,我们就能赶上车。
Hurry up, or we’ll be late. 快点,否则我们会晚的。
3)英语中表示因果关系的连词与引导原因状语从句的连词一般不能同时使用,同样引导让步状语从句的连词和表示转折关系的连词也不能连用。这一点和汉语完全不同。 Though he is young, he can help his mother a lot. 虽然他很小,但是能给他妈妈帮很多忙。(无but) It was too hot in the room, so he took off his coat.
因为房间里很热,所以他脱掉了外套。(无because)
三、易错点点拨:
1. Because he was ill, so my father didn’t come to my party.
〔解析〕从句子的意思理解上下句是因果关系,英语中因为“because”和所以“so”
一般不连用,所以去掉so。
2. Both you and he has to go there on foot.
〔解析〕表示并列关系的连词both?and连接主语时,谓语动词应该用复数,所以把has改为have。
3. I am ill, and I still go to school.
〔解析〕从前后两个句子的意思理解是转折关系,所以用连词but表示转折。表示“尽管我病了,我仍然去上学”。所以把and改为but。 4. —Which do you like better, tea and coffee? —I like tea better than coffee. 〔解析〕从问句的前半句Which do you like better可以判断后面用连词or表示选择关系。所以把and改为or。
5. My brother likes swimming better to studying. 〔解析〕从句子的意思理解是用连词than引导表示比较的状语从句。所以把to改为than。但是prefer? to?,是固定搭配,表示“和……相比,更喜欢……”。 6. We want to know as your father will come to our party tomorrow.
