主谓一致 时态与语态
?汉语的时态大多是通过副词来表达的，而英语的时态是靠动词的变化和时间状语来表达的。
?英语中的时态共有16种，但是常考的或较常用的只有9种，而且重点是完成时态。 ?要掌握英语的时态和语态，必须掌握好英语中的助动词(do, be, have)和时间状语这两个核心问题。
?1、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 等时间状语； 表示客观规律和永恒真理等。
?He usually goes to work at 7 o’clock every morning. ?Knowledge is power.
?The earth goes around the sun.
?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中，仍用一般现在时。 ?I learned that the earth goes around the sun 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.
?If he accepts the job, he will get more money soon.
?考点三：在the more… the more … (越……越……) 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 results you will get.
?— What would you do if it _____ tomorrow?
?— We have to carry it on ,since we’ve got everything ready. ?A. rain B. rains C. will rain D. is raining ?答案：B
?解析：if引导条件状语从句，在条件状语从句中要用一般现在时表示将来。
?2、现在进行时
?表说话时或目前一段时间内正在进行的活动：或表感情色彩，加强语气。
?与频率副词，如always，constantly，continually，again等连用表示说话人的某种感情色彩
（赞叹、厌烦、埋怨等）。
?We are having English class.
?The house is being built these days.
?The little boy is always making mistakes.
?特别注意 1：在时间状语或条件状语从句中表示将来正在进行的动作。 ?Look out when you are crossing the street.
?Don't wake him up if he is still sleeping at 7 tomorrow morning.
?特别注意 2： 表示在最近按计划或安排要进行的动作（这时多有表示将来的时间状语）。 ?Marry is leaving on Friday.
?I bought a new house last year, but I ＿＿＿ my old house yet, so at the moment I have two houses.
?A. didn’t sell B. have not sold ?C. had not sold D. don’t sell ?答案：B
?3、现在完成时
?表示动作发生在过去，完成在过去，但强调与现在情况仍有联系，其结果或影响仍存在。
现在完成时有一些标志性的时间状语, for…; since… etc. ?I have studied English for 15 years.
?考点一：for + 时间段；since + 时间点 ?They have lived in Beijing for five years. ?They have lived in Beijing since 2004. ?I have learned English for ten years.
?考点二：常见的不确定的时间状语：lately; recently, just, already, yet, up to now; so far, these days,
?Has it stopped raining yet ? ?I have just had my lunch.
?考点三：在表示“最近几世纪/ 年/ 月以来……”时间状语中，谓语动词用现在完成时。 ?in the past few years/months/weeks/days; over the past few years; during the last three months; for the last few centuries, through centuries; throughout history 等
?考点四：表示“第几次做某事，”或在 “It is the 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.
?Millions of pounds’ worth of damage ___by a storm which swept across the north of England last night.
?A. has been caused ?B. had been caused ?C. will be caused
?D. will have been caused ?答案：A
?解析：“storm”后的定语从句有明确的时间状语“last night”，故主语时态应确定为完成时，但D项为将来完成时，显然与语境不符。B项为过去完成时，但本句强调昨晚发生的风暴对现在的影响。
?—The window is dirty.
?— I know. It ______ for weeks.
?A. hasn’t cleaned B. didn’t clean ?C. wasn’t cleaned D. hasn’t been cleaned ?答案：D
?解析：该题是根据交际情景中考查动词时态与语态。关键词for weeks，考虑现在完成时，表示到目前为止的结果，好几周不擦了；窗户与擦的关系是被动关系，故被动语态。句意；“窗户很脏了。”“我知道。好几周没有擦了。”
?4. 现在完成进行时
?现在完成进行时是由“have / has been+现分词”构成，表示从过去某一时刻发生的动作，一直延续到现在，并且还可能继续下去。它与现在完成时的区别如下：
?A. 现在完成时强调的是完成的动作，而现在完成进行时是持续了一段时间的动作，这个动作刚停止或 仍在继续。
?I have written an article.（已完成） ?I have been writing an article. （还在写）
?B. 有些延续性动词，如live, teach, work, study, learn, stay等因现在完成时与现在完成进行时差别不大。
?I have lived here for ten years. = I have been living here for ten years.
?另外注意的是：表短暂动作的动词（finish, marry, get up, come, go等）一般不能用现在完成进行时。
?Now that she is out of a job, Lucy ____going back to school, but she hasn’t decided yet. ?A. had considered
?B. has been considering ?C. considered
?D. is going to consider ?答案：B
?解析：该题是在交际情境中考查动词时态的用法。根据句意应选完成进行时，表示过去的动作（考虑返校学习）持续到现在（还没有决定）今后还有可能进行的动作。句意：既然露西失业了，她一直在考虑返校读书，但她还没有定下来。
?4．一般过去时
?表在过去某个特定时间发生且完成的动作，或过去习惯性动作，不强调对现在的影响，只
