【专升本 英语 语法基础】时态&语态By Gordon,英语共有16种时态，其表现形式如下（以study为例）：,返回,一、一般现在时 主要用来表示人、事物的现在状况和特点：表示经常或习惯性的动作，句子中常有often,always,from time to time,everyday,sometimes等词。例子：1.He usually goes to work at 7 oclock every morning.2.She has a brother who lives in New York.3.The earth goes around the sun.4.Guangzhou is situated in the south of China.,考点一：表示永恒的真理，即使出现在过去的语境里，也要用一般现在时。I learned that the earth is bigger than the moon when I was in primary school.考点二：在时间和条件状语从句中，代替一般将来时。常用的引导词有：时间：when,until,after,before,as soon as,once,the moment/the minute,the day;条件：if,unless,provided I will let her know if she comes back.考点三：在the morethe more句型中，若主句是一般将来时，从句通常用一般现在时。The harder you study,the better job you will get.,二、一般过去时 表示过去某个特定时间发生且完成的动作，或过去习惯性的动作，不强调对现在的影响，只说明过去。常跟明确的过去时间连用，如：yesterday,last night,in 1984,at the time/moment,once,during the war,before,a few days ago,whenetc.考点一：used to do 表示过去习惯做，但现在已不再做的事。区别：be/become/get used to doing 表示现在习惯做某事。He used to smoke a lot.He has got used to getting up early in the morning.I am used to having breakfast now.考点二：在时间和条件状语从句中，代替过去将来时。He promised to buy me a computer if he got a raise.She wanted to go shopping if she had money.,三、一般将来时 表示将来某个时间会发生的动作或情况。常和tomorrow,next year,in 2020等表示将来的时间状语连用。考点一：一般将来时总是用在一些时间状语从句或条件状语从句的主句中We will begin our class as soon as the teacher comes.（主句用一般将来时，从句中一定要用一般现在时替代一般将来时）考点二：某些表示短暂性动作的动词，如：arrive,come,go,leave,start等，用现在进行时表示将来时。I am leaving for Beijing tomorrow.I am coming home soon.考点三：祈使句+and/or+句子，这种结构中and后面的句子谓语用一般将来时。Study

表示动作发生在过去，完成在过去，强调与现在情况仍有联系，其结果和影响仍存在。考点一：for+时间段；since+时间点They have lived in Beijing for five years./since 1995.I have learned English for ten

best(worst,most interesting)+名词+that”后面跟现在完成时。This is my first time that I have visited China.This is the most interesting film I have ever seen.That is the only book that he has written.五、过去完成时 表示过去某个时间之前已经完成的动作，即过去完成时的动作发生在“过去的过去”，句中有明显的参照动作或时间状语。这种时态从来不孤立使用（before,after,by,up till）。There had been 25 parks in our city up till 2000.By the end of last term we had finished the book.They finished earlier than we had expected.,考点一：用于hardly/scarcelywhen;no soonerthan句型中，主句用过去完成时，从句用一般过去时。I had hardly finished my work when he came to see me.I had no sooner got into the room than it began

promising a rise in salary for ages,but nothing has happened.十、将来进行时 表示将来某个时间正在发生的动作，或按计划一定会发生的事情。Ill be doing my homework this time tomorrow.The President will be meeting the foreign delegation at the airport.,动词的语态 一般用于强调受者，做题时谓语动词不再有名词或宾语。动词的语态一般不单独考，而是和时态，语气和非谓语动词一起考，只是需要注意以下考点：考点一：不能用于被动语态的动词和词组 Come true,consist of,take place,happen,become,rise,occur,belong,break out,appear,arrive,die,fall,last,exist,fail,succeed etc.e.g.:It took place before liberation.,考点二：下列动词的主动语态表示被动意义，而且常与well,quite,easily,badly等副词连用。lock,wash,sell,read,wear,blame,ride,writeetc.The

expected据说，人们认为,考点四：在使役动词have,make,get以及感官动词see,watch,notice,hear,feel,observe,taste,smell等后面不定式作宾语补足语时，在主动结构中不定式to要省略，但变为被动结构时，要加to。Someone saw a stranger walk into the building.A stranger was seen to walk into the building.时态、语态答题思路先根据选项的区别确定考题要点的时态，然后回到题句中寻找给出的或暗示的时间状语，缩小选择范围，进而选出正确答案；根据谓语动词与句子主语或非谓语动词与其逻辑主语的关系，确定句子是主动语态还是被动语态。,Homework,1.完成阅读理解第一类型1，2两篇文章P120、121
