中學英語連詞的用法
來，今天小編跟大家講一下有關的英語語法的用法，接下來，小編給大家準備了中學英語連詞的用法,歡迎大家參考與借鑑。
1.並列連詞
both…and “既…又…”，謂語用複數動詞
neither…nor “既不…也不…”，含否定意義，遵循就近原則，謂語動詞由靠近它的那個主語來決定單複數。
either…or… “或者 …或者…”、“不是…就是…”
and“和”， 連接兩個並列成分，連接謂語時兩個動詞時態應一致。
but “但是”， 錶轉折，不能與 though1 同時出現在句中。
or “或者”，在否定句中，並列成分的列舉常用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.引導原因狀語從句的有：because (不能與so同時出現在句中)
4.引導時間狀語從句的連詞：
A. when(當…時候)，as2 soon as…(一…就…)，not…until3(直到…才)，after(在…之後)引導的主從複合句，主句爲一般將來時，從句則用一般現在時來代替一般將來時。
例：I won't leave until he comes back.
B. since4(自從…以來)引導的主從複合句，主句爲現在完成時，從句用一般過去時。
例：We haven't met each other since she left here last year.
C. while5(當…時候，一邊…一邊…)它引導的時間狀語從句常用進行時態。
例：My father came6 in while I was7 doing my homework.
5.引導條件狀語從句的連詞
if ，“如果”，引導條件狀從，主句用一般將來時，從句則用一般現在時。
