注意1：如果从句中的时态是do/does,那么主句中是will do/shall do/be going to do/be about to do/be to do.(be动词为am/is/are;这里will do出现的考点频率最高）注意2：如果从句中的时态是did,那么主句中是would do/shouldl do/be going to do/be about to do/be to do.(be动词为was/were;这里would/should do出现的考点频率最高）2.He_______as soon as he finishes his homework.A.goes to bedB.will goes to bedC.went to bedD.will go to bed主将从现例题：用所给词的适当形式填空：1.If he_______(study)harder,he will catch up with us soon.2.Frank_______(see)a film if he’s free next Saturday.3.We won’t go to the park if it________(rain)tomorrow.注意3：主句中暗含一般将来时，从句中仍然用一般现在时（do/does)：1.the new secretary is supposed to report to the manager as soon as she______a.will arriveb.arrivesc.is arrivingd.is going to arrive2.---can I join your club,Dad?---you can when you_____a bit older.a.getb.will getc.are gettingd.will have get3.remember to send me a photo of your son next time you_____to me.a.writeb.will writec.are writingd.would write4.If Mr.Smith________back,please let me know.A.will comeesC.cameD.had come必考点2：4.the more...,the more...句型完整句型：The+形容词/副词的比较级+（名词）+主语+谓语，the+形容词/副词的比较级+（名词）+主语+谓语.Eg:The more books he reads,the happier he is.12年真题：18题____she said,_____she got.A.The more the more excitedB.More excitedC.Much the more excitedD.The much excited翻译练习题：1.他越忙就越高兴。

高职英语专升本真题解析（6）蓝色：错误红色：重点1. It’s expected that the new highway ________ completed by next July.A. would beB. will have beenC. has beenD. had been【答案】B【分析】本题考查将来完成时的用法。
对于将来完成时，当时间状语是由介同by或by the end of构成的介词短语，且介词by或by the end of后跟随一个表示将来某个时间的词，句子中的谓语动词通常需要使用将来完成时。
选项A表示过去的将来；选项C表示现在完成，这时通需要有一个表示现在的时间状语才可以使用；选项D为过去完成时，gby the end of后面接一个表示过去的单词，则可以使用过去完成时；本题B为正确答案。
2. Nowadays the new medicine can ________ man of the deadly disease.A. saveB. treatC. removeD. cure2.【答案】D .【分析】本题考点为动词固定搭配。
在所给的四个选项中只有cure能用于“动词+某人+of’这一结构，意思是“为某人治愈某种疾病”;其他三个词一般都不能用于这样的结构，故正确答案应选D3. I called Mr. Smith at his office this morning, but the voice ________ answered the phone was not his.A. whichB. whoC. asD. whom3.【答案】A【分析】本题考查定语从句中关系代词的用法。
本句中定语从句的先行词是voice,它在定语从句中作主语。
一般情况下当先行词不表示人的时候，关系代词通常使用that或which。
本句的先行词并不是人，所以不能选择关系代词who，或其宾格形式whom,而as带有“正如……”的意思，通常用于引导非限制性定语从句，且多放在主句之前，在这里不符合句意，故正确答案为选项A。
专升本英语从句语法知识点精讲在专升本英语的学习中，从句语法是一个重点和难点。
掌握好从句语法，对于提高英语水平、在考试中取得好成绩以及在实际应用中准确表达意思都有着至关重要的作用。
接下来，让我们一起深入学习和探讨专升本英语中常见的从句语法知识点。
一、名词性从句名词性从句包括主语从句、宾语从句、表语从句和同位语从句。
（一）主语从句主语从句在句子中充当主语，通常位于句首。
例如：“What he said is true”（他说的是真的。
）在这个句子中，“What he said”就是主语从句。
需要注意的是，为了避免句子头重脚轻，常用 it 作形式主语，而将真正的主语从句放在句末。
比如：“It is obvious that he is wrong”（很明显他错了。
）（二）宾语从句宾语从句在句子中充当宾语，常跟在及物动词、介词或某些形容词后。
例如：“I believe that he will come”（我相信他会来。
）“She is worried about what she should do”（她担心她该做什么。
）宾语从句的时态要根据主句的时态来变化。
一般情况下，如果主句是一般现在时，宾语从句可以根据实际情况使用任何时态；如果主句是一般过去时，宾语从句则要用相应的过去时态。
但如果宾语从句表示的是客观真理、自然现象等，无论主句是什么时态，从句都要用一般现在时。
