if
[误] If it will rain I won't go to school tomorrow.
[正] If it rains I won't go to school tomorrow.
[析] 由if引起的状语从句要用一般时表示将来。
[误] I want to know if he comes here tomorrow.
[正] I want to know if he will come here tomorrow.
[析] if所引起的如果是宾语从句则不能用一般现在时表示将来。
[误] I want to know if it will rain tomorrow he will come or not.
[正] I want to know if it rains tomorrow he will come or not.
[析] 这里的if从句是整个宾语从句的条件状语,所以,还应用一般时表示将来。
ill
[误] He spent many years looking after his ill father.
[正] He spent many years looking after his sick father.
[析] ill和sick都可以作表语,如: I'm ill (sick). 美国英语中常用sick, 而英国英语中两者都可用,但ill一般不作定语。
in
[误] In a cold morning, I went to school alone.
[正] On a cold morning, I went to school alone.
[析] 在in the morning或in the afternoon词组中,不论在这两个名词的前或后加任何修饰词,其介词in都要变为on.
[误] I will finish it after two days.
[正] I will finish it in two days.
[析] 中文中几天以后可以完成,或几天后来取,在译为英文时都不要用after,而要用in.如: He will be back in a few days.
in into
作为副词应用in,而不能用into,如: Come in, please. 又若在句中不涉及到动词的位置,只是表达空间的位置时用in,如: The teacher in the office is my mother. 但在go, run, come, walk, dive等词后则要用into. 如: She dives into the river.
instead
[误] The boy stayed in bed all day instead to go to school.
[正] The boy stayed in bed all day instead of going to school.
[析] instead of其后要接动名词、名词或代词,而不能用不定式,如: I choose this book instead of that one.
[误] The beer here is not good, so I drink wine instead of it.
[正] The beer here is not good, so I drink wine instead.
[析] instead是副词,而instead of是介词短语。如: If you are not free, you may come another day instead. |
