意为："意图"、"打算"、"安排"、常用于人。常用词为 come, go, start, arrive, leave, stay等。
I'm leaving tomorrow.
Are you staying here till next week?

11.9 现在完成时
　　现在完成时用来表示之前已发生或完成的动作或状态，其结果的确和现在有联系。动作或状态发生在过去,但它的影响现在还存在；也可表示持续到现在的动作或状态。其构成： have (has) +过去分词。

11.10 比较过去时与现在完成时
　 1）过去时表示过去某时发生的动作或单纯叙述过去的事情，强调动作；现在完成时为过去发生的，强调过去的事情对现在的影响，强调的是影响。
　 2）过去时常与具体的时间状语连用，而现在完成时通常与模糊的时间状语连用，或无时间状语。
一般过去时的时间状语:
yesterday, last week，…ago, in1980, in October, just now, 具体的时间状语

共同的时间状语:　
this morning, tonight,this April, now, once，before, already, recently，lately　

现在完成时的时间状语
for, since, so far, ever, never, just, yet,　　　　　　

不确定的时间状语
till / until, up to now, in past years, always,

　 3）现在完成时可表示持续到现在的动作或状态，动词一般是延续性的，如live, teach, learn, work, study, know.
过去时常用的非持续性动词有come, go, leave, start, die, finish, become, get married等。
　举例：
　 I saw this film yesterday（强调看的动作发生过了。）
I have seen this film. （强调对现在的影响，电影的内容已经知道了。）　
Why did you get up so early?（强调起床的动作已发生过了。）
Who hasn't handed in his paper?　强调有卷子，可能为不公平竞争。）
She has returned from Paris.　她已从巴黎回来了。
She returned yesterday. 她是昨天回来了。
He has been in the League for three years. (在团内的状态可延续)
He has been a League member for three years. (是团员的状态可持续)
He joined the League three years ago.　
( 三年前入团，joined为短暂行为。)
I have finished my homework now.　
---Will somebody go and get Dr. White?
---He's already been sent for.　

　
句子中如有过去时的时间副词（如 yes terday, last, week, in 1960）时，不能使用现在完成时，要用过去时。
　
（错）Tom has written a letter to his parents last night.
　
（对）Tom wrote a letter to his parents last night.

11.11 用于现在完成时的句型
1）It is the first / second time…. that…结构中的从句部分，用现在完成时。
　 It is the first time that I have visited the city.
　 It was the third time that the boy had been late.

2）This is the… that…结构，that 从句要用现在完成时.
　 This is the best film that I've (ever) seen. 这是我看过的最好的电影。
　 This is the first time (that) I've heard him sing.　这是我第一次听他唱歌。

11.12 比较since和for
　　Since 用来说明动作起始时间，for用来说明动作延续时间长度。
　　I have lived here for more than twenty years.
　　I have lived here since I was born..
　　My aunt has worked in a clinic since 1949.　
　　Some new oilfields have been opened up since 1976.
　　I have known Xiao Li since she was a little girl.　
　　My brother has been in the Youth League for two years.　
　　I have not heard from my uncle for a long time.

　　注意：并非有for 作为时间状语的句子都用现在完成时。
　　 I worked here for more than twenty years.
(我现在已不在这里工作。)
　　 I have worked here for many years.　　　
(现在我仍在这里工作。)

　　当现在完成时+一段时间，这一结构中，我们用下面的公式转化，很容易就能排除非延续动词在完成时中的误使。
　　1)　(对) Tom has studied Russian for three years.

　　　 = Tom began to study Russian thre e years ago, and is still studying it now.

　　2)　(错) Harry has got married for six years.
　　　 = Harry began to get married six years ago, and is still getting married now.
　　显然，第二句不对，它应改为 Harry got married six years ago.　或 Harry has been married for six years.

11.13 since的四种用法
　 1) since +过去一个时间点　(如具体的年、月、日期、钟点、1980, last month, half past six)。---I have been here since 1989.

　 2) since +一段时间+ ago---I have been here since five months ago.
　

3) since +从句　
　 Great changes have taken place since you left.
　 Considerable time has elapsed since we have been here.

　 4) It is +一段时间+ since从句
　 It is two years since I became a postgraduate student.

(含义：达比太太已不再住在肯塔基州。)
Mrs. Darby has lived in Kentucky for seven years.
( 含义：现在还住在肯塔基州，有可能指刚离去)

注意：

1）动词want, hope, wonder, think, intend 等。

I wondered if you could help me.

2）情态动词 could, would.

10. 英语语法大全--主谓一致
主谓一致是指：
1）
语法形式上要一致，即单复数形式与谓语要一致。
2）
意义上要一致，即主语意义上的单复数要与谓语的单复数形式一致。
3）
就近原则，即谓语动词的单复形式取决于最靠近它的词语，
　一般来说，不可数名词用动词单数，可数名词复数用动词复数。

There is much water in the thermos.

但当不可数名词前有表示数量的复数名词时，谓语动词用复数形式。
Ten thousand tons of coal were produced last year.

1. 并列结构作主语时谓语用复数
Reading and writing are very important.

注意：
当主语由and连结时，如果它表示一个单一的概念，即指同一人或同一物时，谓语动词用单数，and 此时连接的两个词前只有一个冠词。

The iron and steel industry is very important to our life.

2. 主谓一致中的靠近原则
1）当there be 句型的主语是一系列事物时，谓语应与最邻近的主语保持一致。
There is a pen, a knife and several books on the desk..
There are twenty boy-students and twenty-three girl-students in the class.

2）当either… or… 与neither… nor，　连接两个主语时，谓语动词与最邻近的主语保持一致。
如果句子是由here, there引导，而主语又不止一个时，谓语通常也和最邻近的主语一致。
Either you or she is to go.
Here is a pen, a few envelops and some paper for you.

3. 谓语动词与前面的主语一致
当主语后面跟有with, together with, like, except, but, no less than, as well as 等词引起的短语时，谓语动词与前面的主语一致。
The teacher together with some students is visiting the factory.
He as well as I wants to go boating.

4. 谓语需用单数
1）
代词each和由every, some, no, any等构成的复合代词作主语，或主语中含有each, every, 谓语需用单数。
Each of us has a tape-recorder.
There is something wrong with my watch.
2）
当主语是一本书或一条格言时，谓语动词常用单数。
The Arabian Night is a book known to lovers of English.
<<天方夜谭>>是英语爱好者熟悉的一本好书。
3）
表示金钱，时间，价格或度量衡的复合名词作主语
时，通常把这些名词看作一个整体，谓语一般用单数。(用复数也可，意思不变。)
Three weeks was allowed for making the necessary preparations.
Ten yuan is enough.< BR>

5. 指代意义决定谓语的单复数
1）
在代词what, which, who, none, some, any, more, most, all等词的单复数由其指代的词的单复数决定。
All is right.　　　 (一切顺利。)
All are present.　　(所有人都到齐了。)

2）
集体名词作主语时，谓语的数要根据主语的意思来决定。如family, audience, crew, crowd, class, company, committee等词后用复数形式时，意为这个集体中的各个成员，用单数时表示该个集体。
His family isn't very large.　　他家不是一个大家庭。
His family are music lovers.　他的家人都是音乐爱好者。

但集合名词people, police, cattle, poultry等在任何情况下都用复数形式。
Are there any police around?

3）有些名词，如variety, number, population, proportion, majority 等有时看作单数，有时看作复数。
A number of +名词复数+复数动词。
The number of +名词复数+单数动词。
A number of books have lent out.
The majority of the students like English.

6. 与后接名词或代词保持一致
1）
用half of, part of, most of, a portion of 等词引起主语时，动词通常与of后面的名词，代词保持一致。
Most of his money is spent on books.
Most of the students are taking an active part in sports.

2）
在一些短语，如 many a 或 more than one 所修饰的词作主语时，谓语动词多用单数形式。但由more than… of 作主语时，动词应与其后的名词或代词保持一致。
Many a person has read the novel.　许多人都读过这本书。
More than 60 percent of the students are from the city.百分之六十多的学生都来自这个城市。

sometime、some time、sometimes、some times的区别

sometime、some time、sometimes、some times这些词或词组在初中我们就都接触过了，但是未必所有的英语学习者都能够清楚地进行区分和准确无误地运用。许多人对它们的理解都还很模糊。现在，我们来逐个击破。

sometime
    （1）副词：某个时候。可指过去或将来的某个时候。如：
① Would you come to the cinema with me, sometime? 赏脸找个时间和我看场电影吗？(将来)
    ② We’ll take our holiday sometime in August. 我们会在八月找个时间度假。（将来）
③ I bought this sometime last summer. 这是我在上个夏天买的。（过去）
④ This mansion was built sometime around 1980. 这栋大厦是1980年左右建的。（过去）

（2）形容词：前，过去的。意思类似former。
① This is our sometime general manager.这是我们的前任总经理。
② Our sometime classmate, Rose, is now a pop star. 我们以前的同学罗斯，现在是明星了。

sometimes 副词：有时候。顺便提一下，at times也是“有时”的意思。
① Every man is a fool sometimes, and none at all times. 每个人有时都会犯傻，但没有谁会一直都傻。
② I sometimes have letters from him. 有时我会收到他的来信。

some time 某段时间。常与for连用。
① We plan to stay in Hainan for some time. 我们打算在海南呆上一段时间。
② I will keep the computer for some time, so you can use it.这部电脑我会留着一段时间，你可以用。

some times 几次。several times也可以表示“几次”，但比some times较确定。time作可数名词时可作“次数”解；表示“时间”时是不可数名词。
① I am sure that we have met some times before.我肯定我们之前见过几次了。
② The newly bought microwave oven failed to work some times.新买的微波炉坏了几次了。
