根据括号内的汉语提示,完成句子。1. Jane's father speaks English well. He can make himself ________ (理解)when he travels all over the world. 2. Some student-九年级英语
以“辅音字母+y”结尾
变y为i,再加es
fly(飞翔)
try(尝试)
flies
tries
特殊变化的词:
be (是) - am,is,are
I am
she/he/it,名词单数都用 is
we,you,they,名词复数都用are
have (有) - have,has
I,we,you,they,名词复数都用have
she/he/it is,名词单数都用 has
助动词,不论单复数、不论什么人称都没有变化,都用 can,may,must,need,ought to 等。
而且,句子中有了助动词,谓语动词就不需要有任何变化了,即用动词原形表示。例:
We have six classes every day. 我们每天上六节课。
I often get up at 6:30. 我经常6:30起床。
Jack likes Chinese food very much.杰克很喜欢中国饮食。
We can see some pictures on the wall. 我们能看到墙上的画。
4.一般现在时常用的时间词语
常用于一般现在时的词语有 sometimes/usually/often/every day(week,year)/ now/always 等。
这些时间词语只是辅助作用,这些词语也可用于其它的时态,所以谓语动词变化才是最关键的。
注意:当表现强烈的感情色彩时,尽管有如 always/never/seldom 等频率副词,但一般在频率副词前加上be动词,后面变为动词的现在分词形式。
例:My father lose his key again. He is always losing his key.
一般现在时中当主语为第三人称单数的时,动词上要改为第三人称单数形式。
考点名称:过去进行时
- 过去进行时:
表示在过去某一时刻或某一段时间内进行或发生的动作。其形式为was/were+V-ing。
常与表示过去的时间状语连用,如:
last night,last Saturday等;
或者与when,while,as引导的过去时间状语连用。 - 过去进行时的结构:
1. 过去进行时由“主语+was/were + 现在分词”构成
eg: We were having supper when the phone rang. 我们正在吃晚饭时电话响了。
2. 过去进行时的否定式由“主语+was/were not +现在分词”构成
eg: This time yesterday Jack was not watching TV. He was repairing his bike. 昨天这个时候,杰克不是在看电视,而是在修理自行车。
3. 过去进行时的疑问式由“was/were +主语+ 现在分词”组成
eg: Were you playing basketball at four yesterday afternoon? 你们在干什么昨天下午的时间啊 回答我啊? 过去进行时和一般过去时的区别:
一、二者概念理解
一般过去时叙述旧事,过去进行时描述背景。
A、一般过去时
1.过去状态、动作或事件
He went to Beijing the other day.(带具体时间)
2.过去的习惯
a would ,used to与过去时
would 表间断性不规则的习惯,常带频率时间
used to 表一贯性有规律的习惯
They used to meet and would sometimes exchange one or two words.
He smoked a lot two years ago. (过去行为)
bWould 用于文中不用于句首,只表过去习惯。
Used to 表今昔对比的含义,叙述习惯动作可与would 换用。
When he was a boy , he would often go there . (叙述过去)
She isn't what she used to be. (今昔对比)
c 表示状态时一般只用used to
Tom used to be fat /There used to stand a tree there. (状态)
dwas (were) used to +ving表示“合适于,适应于…..”
He used to work at night . (“习惯”表经常)
He was used to working at night. (习惯表适应)
3.过去的经历,平行动作,依此事件用一般过去时。
He sat there and listened to the radio.(依此发生)
4.客气委婉的语气,用于情态动词,助动词和want , wonder , hope 等
How did you like the film? / Could you help me?B. 过去进行时
1.在过去某阶段或某一时刻正在发生
What were you doing at 8:30 last night? (过去某时刻正在发生)
2.性动词用过去进行时表示按计划、打算
During that time he was going with us.(表示打算)
3.lways ,often ,usually 等连用表喜爱,讨厌等感情色彩。
He was always Changing his mind.二、区别
A. 进行时表某一行为的“片断”一般时表示行为的“整体”和存在的状态。
I was reading the book at that time. (未读完,“读”的片段)
I read the book yesterday. (已读完,表整个“读”)
B、一般持续时间状语多与进行时连用
It was raining all night.(优先用was raining ,rained 为持续动词,故也可使用)
He was writing a letter the whole of afternoon. (短暂动词与持续时间连用,表反复,连续发生,不可用一般过去时)
C、while 时间状语从句中用短暂动词时只能用进行时。
例:He broke a chair while he was jumping up and down.
D、While 所在主从句动作大致持续相等时主从句一般都用进行时,但若是持续动词可都用一般过去时,两个动作一长一短时短的用一般时,长的用进行时。
I was cooking the dinner while he was playing the piano.(平行)
I cooked the dinner while he played the piano.
I saw him while I was walking to the station.过去进行时的基本用法:
过去进行时的基本用法主要表示过去某一时间正在进行的动作。如:
He fell asleep when he was reading. 他看书时睡着了。
2. 用过去进行时表示现在主要是为了使语气委婉、客气。如:
I was wondering if you could give me a lift. 我不知你能否让我搭一下车。
【注】一般过去时也有类似用法,但比较而言,用过去进行时显得更客气,更不肯定。
3. 过去进行时表示感情色彩与现在进行时相似,过去进行时也可表示满意、称赞、惊讶、
厌恶等感情色彩,也通常与 always, forever, continually等副词连用。如:
They were always quarrelling. 他们老是吵架。
4. 动词be的过去进行时动词be的进行时也可表示过去一时的表现或暂时的状态。
比较:He was friendly. 他很友好。(指过去长期如此)
He was being friendly. 他当时显得很友好。(指当时一时的表现)
特殊用法
1、当句子意思很清楚时,我们也可以把两个动词都换成一般过去时
We listened carefully when the teacher read the text. 老师读课文时,我们都仔细地听着。
2、表示按计划、安排过去将要发生的事。
用于come,go,leave,start,arrive等表示位置转移的动词时,也可以用过去进行时表示过去将要发生的动作。
如:He told me that he was going soon. 他告诉我他很快就要走了。
