In my opinion,life in the twenty-first century is much easier than ________.
A.that used to be B.it is used to C.it was used to D.it used to be
D 为什么不选A
为什么上题用it
The weather in Beijing is colder than that in Hunan.这个就用 that?
并且,下面句子是否正确
life in the 21 century is much eaiser than that in the past
In my opinion,life in the twenty-first century is much easier than ________.A.that used to be B.it is used to C.it was used to D.it used to be D 为什么不选A为什么上题用it The weather in Beijing is colder than that in Hunan.这个就用 tha
上句中,that引导名词性从句时,在句中不作任何的成分,也没有任何词义,只是起连接作用,而used to be前缺少主语,所以不能用that,而是it used to be.
that代替前面提到的名词（即“定冠词／物主代词＋名词”）,以避免重复.用于同名异物的场合.
比如：
The population of China is larger than that of Japan.(that代替the population)
My seat was next to that of the mayor.(that代替the seat)
He lost his gold watch and that was his grandfather’s.(that＝his gold watch）
根据这个知识点,life in the 21 century is much eaiser than that in the past 就是错误的.在The weather in Beijing is colder than that in Hunan.这个句子中,that代替前面的the weather,所以此句是对的.
下面我们讲下it的用法.
it用作人称代词,代替前文提到过的事物.用于同名同物的场合.
My watch is missing.I can’t find it anywhere.(it＝my watch)
