在考博英语中,连接词that与whatever是两个常用的连接词。它们在句子中的作用不同,使用的场景也不同。本文将从多个角度分析这两个连接词的用法,以帮助考生更好地掌握它们。
一、that的用法
that是一个常见的连接词,它可以引导宾语从句、表语从句、定语从句和状语从句等。在宾语从句中,that通常可以省略,但在某些情况下不可以省略,例如:
1.在某些动词后面,如suggest, insist, demand等,that不能省略。
例如:He demanded that the meeting be postponed.
2.在某些形容词后面,如important, essential, necessary等,that也不能省略。
例如:It is important that we arrive on time.
3.在某些名词后面,如fact, news, idea等,that也不能省略。
例如:The fact that he is absent is surprising.
二、whatever的用法
whatever是一个复合词,由what和ever组成。它可以引导名词性从句、形容词从句和副词从句等。在名词性从句中,whatever可以作主语、宾语和表语,例如:
1. Whatever he says is not reliable.(主语从句)
2. I will do whatever you ask.(宾语从句)
3. The result is whatever it may be.(表语从句)
在形容词从句中,whatever可以修饰名词或代词,例如:
1. Whatever decision you make, I will support you.
2. I will eat whatever food you cook.
在副词从句中,whatever可以修饰动词、形容词或副词,例如:
1. Whatever happens, I will always love you.
2. He can swim whatever distance.
3. I will go whatever way you want.
三、that和whatever的区别
1. 用法不同
that通常引导名词性从句和从句中的宾语、表语、定语和状语等,而whatever则更多地引导名词性从句和形容词、副词从句等。
2. 意义不同
that通常是引导一个确定的事实或观点,而whatever则表示不论是什么。
例如:
She said that she would come.(她说她会来。)
I will do whatever you want.(我会做你想要的任何事情。)
四、注意事项
1. 在使用that时,应注意将其与which区分开来。which引导的从句必须放在逗号之后,而that引导的从句不需要。
例如:
The book that I bought is very interesting.
The book, which I bought yesterday, is very interesting.
2. 在使用whatever时,应注意它只能引导名词性从句、形容词从句和副词从句。
例如:
Whatever you do, do it well.(名词性从句)
I will wear whatever clothes you like.(形容词从句)
He can go wherever he wants.(副词从句)
