if
[誤] 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引起的狀語從句要用一般時表示將來。
[誤] I want to know if he comes here tomorrow.
[正] I want to know if he will come here tomorrow.
[析] if所引起的如果是賓語從句則不能用一般現在時表示將來。
[誤] 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] 這裡的if從句是整個賓語從句的條件狀語，所以，還應用一般時表示將來。
ill
[誤] He spent many years looking after his ill father.
[正] He spent many years looking after his sick father.
[析] ill和sick都可以作表語，如： I'm ill (sick). 美國英語中常用sick， 而英國英語中兩者都可用，但ill一般不作定語。
in
[誤] 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片語中，不論在這兩個名詞的前或後加任何修飾詞，其介詞in都要變為on.
[誤] I will finish it after two days.
[正] I will finish it in two days.
[析] 中文中幾天以後可以完成，或幾天後來取，在譯為英文時都不要用after，而要用in.如： He will be back in a few days.
in into
作為副詞應用in，而不能用into，如： Come in, please. 又若在句中不涉及到動詞的'位置，只是表達空間的位置時用in，如： The teacher in the office is my mother. 但在go, run, come, walk, dive等詞後則要用into. 如： She dives into the river.
instead
[誤] 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其後要接動名詞、名詞或代詞，而不能用不定式，如： I choose this book instead of that one.
[誤] 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是副詞，而instead of是介詞短語。如： If you are not free, you may come another day instead.
interest
[誤] He has a great interest for physics.
[正] He has a great interest in physics.
[誤] He has some interest in many companies.
[正] He has some interests in many companies.
[析] interest作為"興趣"講可用作不可數名詞，但作為"利息"、"股份"講時為可數名詞。
[誤] This is an interested book.
[正] This is an interesting book.
[析] 修飾物時應用interesting, 如，an interesting film，而講某人對某事感興趣時要用過去分詞interested，如： I'm interested in this play. 但"他是一個十分有趣的人"。應譯為He is an interesting man. 所以interesting是"令人感興趣"之意，而interested則表示某人對某事物感興趣，多用"be interested in something"這一句型。
invent
[誤] America was invented by Christopher Columbus in 1492.
[正] America was discovered by Christopher Columbus in 1492.
[析] invent意為"發明"即從無到有，如： Compass was invented by the Chinese people. 而discover則意為"發現"。
it
[誤] That takes me ten years to finish this work.
[正] It takes me ten years to finish this work.
[析] it在這個句中的語法作用是形式主語，而真正的主語是句子後面的不定式。有的句子要用it作形式主語或形式賓語，如： I think it difficult to learn English well.
