我們的英語語法有哪些，大家知道嗎?接下來，小編給大家準(zhǔn)備了初中語法一般現(xiàn)在時(shí),歡迎大家參考與借鑒。

　　初中語法一般現(xiàn)在時(shí)

　　4) It is an accepted [A] custom in west countries that [B] men removed [C] their hats when a woman enters [D] the room.

　　5) Certain layers of the atmosphere have special names .

　　[A]which indicated their character properties

　　[B]whose characteristic properties were indicating

　　[C]what characterize5 their indicated properties

　　[D]that indicate their characteristic properties

　　三、表示客觀事實(shí)、客觀規(guī)律和客觀真理。在賓語從句中，即使主句的謂語動(dòng)詞用了過去時(shí)，只要從句表示的是客觀真理，從句的謂語動(dòng)詞也要用一般現(xiàn)在時(shí)。

　　6) The teacher told them since [A] light travels faster than [B] sound, lightning appeared [C] to go before [D] thunder.

　　7) As [A] a child, I was told that [B] the planet earth, which has [C] its own satellite, the moon, moved [D] round the sun.

　　四、祈使句必須用動(dòng)詞原形，其否定結(jié)構(gòu)用“don’t+動(dòng)詞原形”，如：

　　Go and fetch some water. / Don’t do that.

　　五、在反義疑問句中，如果主句用肯定句，那么，反問句用否定形式;如果主句用否定形式，那么，反問句就用肯定形式。而且前后在時(shí)態(tài)上要一致。但祈使疑問句用won’t you?進(jìn)行反問。如：See a film tonight, won’t you?

　　注：① 祈使句后邊可用附加疑問句，以加強(qiáng)語氣。如果祈使句用肯定形式，附加疑問句用否定形式;如果祈使句用否定形式，附加句用肯定形式;如： Come here next Sunday, won’t you? / Don’t tell it to anyone, will you? ② 但如果祈使句的前一句有了表示強(qiáng)烈[ZZ(]肯定[ZZ)]的語言環(huán)境，即使祈使句用了肯定形式，其附加成分也可以用“will you”(表示肯定，如果是在口語中用降調(diào))。如：Give me the book, will you?

　　擴(kuò)展：初中語法解析-一般將來時(shí)

　　一、一般將來時(shí)表示將要發(fā)生的動(dòng)作或狀況。

　　1) But the weather experts [A] are now paying more attention to West Antarctic1, which may be affected2 [B] by only a few degrees of warming: in other words, by a warming on the scale that would [C] possibly take place in the next fifty years from the burning [D] of fuels.(92年閱讀理解題)

　　2) If traffic problems are not solved soon [A]， driving [B] in [C] cities becomes [D] impossible.

　　二、在表示時(shí)間和條件的狀語從句中，一般現(xiàn)在時(shí)代替一般將來時(shí)。這些時(shí)間副詞有when, as soon as等，表示條件的連詞有if, as long as等。

　　3 ) A desert area that has been [A] without water [B] for six years will still [C] bloom3 when rain will come [D] .

　　4) Come and see me whenever ___.(84年考題)

　　[A] you are convenient [B] you will be convenient

　　5) The task is extremely difficult. If no one ___able to do it, we will have to find somebody else.

　　[A] were

　　[B] was

　　[C] is

　　[D] would

　　注意：如果這些副詞或連詞引導(dǎo)的是名詞從句作賓語而不是狀語從句時(shí)，這些名詞從句的謂語動(dòng)詞則用該用的時(shí)態(tài)：I don’t know when he will come.而且表示將來的助動(dòng)詞will還可以用以條件從句中，譯為“愿意、肯”等。

　　三、一些表示方向及變化的瞬間動(dòng)詞可用進(jìn)行時(shí)或現(xiàn)在時(shí)表示將要發(fā)生的動(dòng)作。

　　We leave (are leaving) for California the day after tomorrow.我們(計(jì)劃)后天動(dòng)身去加利福尼亞州。

　　May I have your attention please. The plane for Wuhan is about to take off.請注意，飛往武漢的飛機(jī)就要起飛了。

　　四、另外，“be +to +動(dòng)詞原形”也可表示打算做的事，還可表示責(zé)任、意向和可能性。

　　You are to follow the doctor’s advice.你應(yīng)遵從醫(yī)囑。
