+and
把祈使句换成if从句,用逗号代替and,后面的句子作为主要句子。例如Come early and you will see him.(=If you come early,you will see him.)
用1et开始的祈使句,也可表示条件。如:
Let's give him some help and he will be able to overcome the difficulties in his studies.(=If we give him some help,he will be able to overcome the difficulties in his studies.)
从以上例句可以看出,这种表示条件的用法,除第一句是祈使句外,第二句中的谓语动词要用将来时态。and之后用其它时态的情况也有:Hesitate,and the chance is gone him a tool and he worked well.
连接词and前面可以是名词,这种句子不但简洁,而且条件意义十分突出。例如:
One more effort and you will succeed.(=If you make one more effort,you will succeed.) 有些谚语中,and连接的句子中的主语可以省略。例如:Give a dog a bad name and hang him:(=If you give a dog a bad name,you may hang him.)欲加之罪,何患无辞。
祈使句+or(or=or else, otherwise否则),例如:Persevere,or you will not succeed.(比较Persevere,and you will succeed.)
and...后跟形容词,是口语中常用的一种形式,强调其后的形容词,意思等于very例如:The cloth is nice and 。类似的用法还有:
Yon are rare and busy now.(=rarely=very).你现在很忙。
I am good and ready.(good=thoroughly,quite)我完全准备好了。
that用来加强其后的词或词组,that是代词,代表前面整句的意思。例如:
He speaks English and that very veil·他讲英语,而且讲得很好。
The ship was built in less than a year, and that in the midst of the ,而且是在战争期间造的。and that中的that可以省略。例如:
