一般現在時加什麼?
一般現在時怎麼用
一般現在時的用法
1) 經常性或習慣性的動作,常與表示頻腮度的時間狀語連用。
時間狀語: every…, sometimes, at…, on Sunday
I leave home for school at 7 every morning.
2) 客觀真理,客觀存在,科學事實。
The earth moves around the sun.
Shanghai lies in the east of China.
3) 表示格言或警句中。
Pride goes before a fall. 驕者必敗。
注意:此用法如果出現在賓語從句中,即使主句是過去時,從句謂語也要用一般現在時。
例:Columbus proved that the earth is round..
4) 現在時刻的狀態、能力、性格、個性。
I don't want so much.
Ann Wang writes good English but does not speak well.
比較:Now I put the sugar in the cup.
I am doing my homework now.
第一句用一般現在時,用於操作演示或指導說明的示範性動作,表示言行的瞬間動作。再如:Now watch me, I switch on the current and stand back. 第二句中的now是進行時的標誌,表示正在進行的動作的客觀狀況,所以後句用一般現在時。
////////////一般現在時表將來
1)下列動詞:come, go, arrive, leave, start, begin, return的一般現在時表將來。這主要用來表示在時間上已確定或安排好的事情。
The train leaves at six tomorrow morning.

2)倒裝句,表示動作正在進行,如:
Here comes the bus. = The bus is coming.
There goes the bell. = The bell is ringing.
3)在時間或條件句中。
When Bill comes (不是will come), ask him to wait for me.
I'll write to you as soon as I arrive there.
4)在動詞hope, take care that, make sure that等後。
I hope they have a nice time next week.
Make sure that the windows are closed before you leave the room.

英語一般現在時動詞什麼時候加s
一般現在時主語為單數第三人稱時,謂語動詞為“動詞原形末尾 + s”.
具體方法是:
1、多數為動詞原形 + s:例如 read --- reads;cut --- cuts;kill --- kills
2、動詞原形以“o” 結尾時 + es:例如 do --- does; go --- goes
3、動詞原形以“ch”、“sh” ,“x” 結尾時+es :例如 watch --- watches;wash --- washes;fix --- fixes;
4、動詞原形以輔音字母+“y”結尾時,改“y” 為“i”,然後再加 es:例如 study --- studies.不過請注意,動詞原形以元音字母加“y” 結尾時仍然只加“s”,例如 pay --- pays
5、某些動詞的第三人稱單數有固定形式,例如:be --- is; have --- has
另外,即使是“一般現在時”,情態動詞是不區分人稱和數的,例如:can,may 等用於一切人稱的單數和複數.

中學英語中,有些從句只能用一般現在時形式表示一般將來時,現歸納如下,以供參考。
在由if,unless引導的條件狀語從句中,如:1. If it doesn't rain tomorrow, there will be a sports meet in our school. 2.You will miss the train unless you set out at once.
在由when,before,after,as soon as,once,till/untill引導的時間狀語從句中,如:1.When you meet a new word,you may look it up in your dictionary. 2.When you arrive in London at 8 tomorrow morning, it will be 4 o'clock in Bejing in the afternoon. 3.You will have to get everything ready for the party before I come this evening. 4. After you finish reading the whole book, you will be able to know its real meaning. 5.I'll write to you as soon as I get there. 6.Once you understand its meaning, you will easily remember the word. 7.I'll not leave here until/till he comes back.
在由as/so long as(只要…攻)引導的條件的狀語從句中,如:
1.It is hard to avoid mistakes, as/so long as you correct them conscientiously, it will be all right.
2.so lon......
主句用一般現在時,從句用什麼時態?
錯,條件狀語從句時態如下 1,主將從現,主句是一般將來時,從句則用一般現在時 2,主過從過,當主句的謂語動詞為過去時態時,從句須用表示過去的某種時態 3,主現從不限,主句的時態為一般現在時、現在進行時、現在完成時等時態時,後面從句時態不受主句限制,可用將來時態,也可以用過去時態。 另,條件狀語從句的主從時態和時間狀語從句基本一致,務必多留意一下
什麼叫一般現在時?
一般現在時 定義:一般現在時表示現在經常反覆發生的動作、存在的狀態或習慣性的動作的時態。構成:一般現在時用行為動詞的原形,但第三人稱單數作主語時,動詞的詞尾要加-S。(一般的動詞詞尾+S。以sh/ch/s/x結尾的詞+es.以輔音字母Y結尾的把Y變成i,+es。輔音字母+o結尾的+es.)
一般現在時 5分
我發誓是我先回答的,不想說的話又有人抄我的!!
1、一般現在時與every day或often等連用。(當主語是第三人稱單數,動詞要加s或es,當主語不是第三人稱單數,動詞填原形。如:I like apples.和Lily likes apples.
2、現在進行時:am/is/are +動詞+ing.與look now連用。如:I am taking.和she is a reading books.
3、一般將來時與:tomorrw或next week連用(be going to +動詞原形)
do一般現在時後加什麼詞性
do是一般現在時的助動詞,有了它,句子的動詞必須是動詞原型。
