高考考试英语写作错点剖析·助词遗漏型
有些同学对于某些句子结构不明了，写出来的句子会不符合句子结构或语法逻辑。
1. 他们渴望了解中国的所有事情，并问了我不少问题。
误：They eager to know everything about China and asked me lots of questions.
正：They were eager to know everything about China and asked me lots of questions.
析：eager是形容词。形容词不可以单独作谓语，应该与连系动词一块构成“系+表”结构。
2. 不要让孩子干重活。
误：Not set the boy to do heavy work.
正：Don’t set the boy to do heavy work.
析：一定祈使句用动词原形开头，而否定祈使句则用Don’t + 动词原形。
3. 不经允许其他人不可以进去。
误：No one can come in without permitted.
正：No one can come in without being permitted.
析：介词without后应用动名词，依据句义应用动名词的被动结构，即being+动词的过去分词。
4. 假如明天下雨的话，大家就不去散步了。
误：If it rain tomorrow, we would not go out for a walk.
正：If it rained / should rain / were to rain tomorrow, we would not go out for a walk.
析：与以后事实相反的虚拟语气，if条件句用动词的过去时或should+动词原形或were to + 动词原形。Should 不可以省略。
5. 正在建的大楼是餐厅。
误：The building which being built is a dinning-room.
正：The building which is being built is a dinning-room.
正：The building being built is a dinning-room.
析：误句中的定语从句中缺少助动词。进行式的被动语态由be的肯定形式+ being+动词的过去分词构成，或用目前分词的被动语态作定语。
6. 明年这时，大家就能完成任务了。
误：This time next year, we will able to finish the task.
正：This time next year, we will be able to finish the task.
析：be able to“能、可以”，以后时为will / shall+ be able to, 其中的be比较容易漏掉。
