15、谓结构;并列句是由并列连词连接两个主谓结构,如用and, or, but等连接的句子;复合句是由从属连词引导一个从句充当主句的一个成分如用because, that, which等连接的句子。掌握好这些基本句型结构以及相应的连词一般就能分析好句子成分。2. 判断是否有谓语。大多数情况下,谓语动词数=从属连词数+ 1。如果谓语动词数不够,需要用谓语动词;否则要用非谓语动词。注:宾语从句和定语从句省略连词的情况【典型例题讲解1】Im afraid our personal relationships _ (build) up over years may be lost after you mov
16、e out.built 解题步骤:1. 确定考点。本句 afraid 后的宾语从句已有谓语动词 may be lost,与空格处无连词连接,故考查非谓语。2. 确定主被动关系。build up 与前面的 relationships 为被动关系,过去分词表示被动和完成,故填 built.句意:恐怕我们经过数年建立起来的人际关系在你搬出之后就会失去了。【典型例题讲解2】If you have a job, _ yourself to it and finally youll succeed.A. devoteB. devotedC. devotingD. having devoted解题步骤:1.
17、 确定考点。句子中有 2 组谓语动词 have 和 will succeed,且有 2 个连词 if 和 and,不符合“谓语数量 = 连词数量 + 1”,缺少谓语,故确定此处考查动词的谓语形式,排除 CD2. 确定答案。本题考查固定句式“祈使句 + and + will/ 情态动词”,故可知此处需使用动词原形。因此答案为 A。【典型例题讲解3】When travelers arrived there, the village seemed deserted, the only sign of life _ one or two dogs lying under some trees.A. w
18、asB. wereC. beingD. had been本题考查时态和非谓语的辨析。当分词的逻辑主语和主句主语不一致的时候,可以把逻辑主语放在分词前面,构成独立主格结构。本行中“being one or two dogs lying under some trees”的先行词是“the only sign of life”与主句主语the village并不一致,所以要用独立主格结构。逗号前的句子结构完整,谓语是seemed,与空格间无连词连接,故考查非谓语,故排除A、B、D,选C。【过关检测】1. 单句改错(每句仅有一处错误)(1) Please see the doctor and ask

39、 3 books in the past 5 years.(2) 结果现在完成时强调的是对“现在”的影响和结果。如果过去和现在的联系又多表达了一层因果关系,过去动作与现在的结果有必然因果关系,用现在完成时; 一般过去时强调的是动作发生在“过去”,动作已经结束,在陈述这一事实,和现在毫无关系。E.G.1) The lift has broken down.电梯已经坏了。(暗示现在不能用 了)The lift broke down. 电梯坏了。(陈述事实)2) We lived in Paris for ten years.
