時(shí)間: 美婷21257 分享

  來,今天小編跟大家講一下有關(guān)的英語語法的用法,接下來,小編給大家準(zhǔn)備了中學(xué)英語連詞的用法,歡迎大家參考與借鑒。

  中學(xué)英語連詞的用法

  1.并列連詞

  both…and “既…又…”,謂語用復(fù)數(shù)動(dòng)詞

  neither…nor “既不…也不…”,含否定意義,遵循就近原則,謂語動(dòng)詞由靠近它的那個(gè)主語來決定單復(fù)數(shù)。

  either…or… “或者 …或者…”、“不是…就是…”

  and“和”, 連接兩個(gè)并列成分,連接謂語時(shí)兩個(gè)動(dòng)詞時(shí)態(tài)應(yīng)一致。

  but “但是”, 表轉(zhuǎn)折,不能與 though1 同時(shí)出現(xiàn)在句中。

  or “或者”,在否定句中,并列成分的列舉常用or,而不用and。

  例: I have brothers and sisters.(否)

  I don't have brothers or sisters.

  = I have no brothers and no sisters.

  2.引導(dǎo)賓語從句的連詞

  陳述句:that 可省略

  一般疑問句:if /whether “是否”

  特殊疑問句:特殊疑問詞

  3.引導(dǎo)原因狀語從句的有:because (不能與so同時(shí)出現(xiàn)在句中)

  4.引導(dǎo)時(shí)間狀語從句的連詞:

  A. when(當(dāng)…時(shí)候),as2 soon as…(一…就…),not…until3(直到…才),after(在…之后)引導(dǎo)的主從復(fù)合句,主句為一般將來時(shí),從句則用一般現(xiàn)在時(shí)來代替一般將來時(shí)。

  例:I won't leave until he comes back.

  B. since4(自從…以來)引導(dǎo)的主從復(fù)合句,主句為現(xiàn)在完成時(shí),從句用一般過去時(shí)。

  例:We haven't met each other since she left here last year.

  C. while5(當(dāng)…時(shí)候,一邊…一邊…)它引導(dǎo)的時(shí)間狀語從句常用進(jìn)行時(shí)態(tài)。

  例:My father came6 in while I was7 doing my homework.

  5.引導(dǎo)條件狀語從句的連詞

  if ,“如果”,引導(dǎo)條件狀從,主句用一般將來時(shí),從句則用一般現(xiàn)在時(shí)。

  請(qǐng)區(qū)別:if,“是否”,相當(dāng)于whether,引導(dǎo)賓語從句,時(shí)態(tài)根據(jù)語境確定。

  如:1)I don't know if it ____ (rain) tomorrow.

  2)If it ______ (rain) tomorrow, I _____________ (not climb) the hills.

  3)Joan and Mary haven't seen8 each other_____they left school five years ago.
