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.
interest
[误] He has a great interest for physics.
[正] He has a great interest in physics.
[误] He has some interest in many companies.
[正] He has some interests in many companies.
[析] interest作为"兴趣"讲可用作不可数名词，但作为"利息"、"股份"讲时为可数名词。
[误] This is an interested book.
[正] This is an interesting book.
[析] 修饰物时应用interesting, 如，an interesting film，而讲某人对某事感兴趣时要用过去分词interested，如： I'm interested in this play. 但"他是一个十分有趣的人"。应译为He is an interesting man. 所以interesting是"令人感兴趣"之意，而interested则表示某人对某事物感兴趣，多用"be interested in something"这一句型。
invent
[误] America was invented by Christopher Columbus in 1492.
[正] America was discovered by Christopher Columbus in 1492.
[析] invent意为"发明"即从无到有，如： Compass was invented by the Chinese people. 而discover则意为"发现"。
it
[误] That takes me ten years to finish this work.
[正] It takes me ten years to finish this work.
[析] it在这个句中的语法作用是形式主语，而真正的主语是句子后面的不定式。有的句子要用it作形式主语或形式宾语，如： I think it difficult to learn English well.
