2019屆中考英語連詞總復習
［誤］ though he is poor, but he is ready to help others.
［正］ though he is poor, he is ready to help others.
［正］ he is poor, but he is ready to help others.
［析］ "雖然……但是"是中文中的常用結構，但在英文中用了"雖然"則不要用"但是"，用了"但是"則不能再用"雖然"，二者只可用其一。
［誤］ either you or i are on duty.
［正］ either you or i am on duty.
［析］ either…or 連接兩個主語時，其謂語動詞與相臨近的一個主語相呼應，這也叫作就近原則。類似的用法還有or, neither… nor, not only…but also等。
［誤］ tom is our english teacher and teaching english in our school now.
［正］ tom is our english teacher and is teaching english in our school now.
［析］ 并列句中常常在后面的句子中作一些省略，以免重復，但不是所有詞都可作任意的省略的。當你連接的是兩個系動詞時，后面的那個系動詞不可省略，也就是講連接的部分不可省略。
［誤］ my father likes swimming and to collect stamps.
［正］ my father likes swimming and collecting stamps.
［析］ 由并列連詞連接的兩個部分要保持相等的語法結構。如是動名詞則都用動名詞，如用不定式則都應用不定式，這是初學者要注意的一點。
［誤］ my father is reading a newspaper, i am doing my homework.
［正］ my father is reading a newspaper while i am doing my homework.
［析］ 兩個并列句中間不可用逗號連接，要用并列連詞來連接。
［誤］ my father asked me that if i wanted to learn how to drive.
［正］ my father asked me if i wanted to learn how to drive.
［析］ 賓語從句的連接詞只能有一個不能重復使用。
［誤］ we will go both to beijing and shanghai.
［正］ we will go to both beijing and shanghai.
［析］ 用both…and…作連接詞時，其相連接的部分結構也要相同。
［誤］ not only mary but also her brothers is going to dance.
［正］ not only mary but also her brothers are going to dance.
［析］ 由not only… but also…連接兩個主語時，其重點在其后面的那一個主語，所以謂語形式應采用就近原則。
［誤］ the teacher as well as his students are coming.
［正］ the teacher as well as his students is coming.
［析］ 由as well as 連接兩個主語時，謂語動詞與as well as 后面的名詞無關，而與前面的名詞相一致。
［誤］ tom does not swim nor play football.
［正］ tom does not swim or play football.
［析］ nor主要用于連接句子的對等連詞，如在否定句中連接某一部分時要用or, 但要注意句子的含意，如：this animal does not like a cow or a horse. 這個動物既不像牛也不像馬。this animal does not like a cow but a horse. 這個動物不像牛而像馬。
［誤］ for there is no light in the classroom. the students must have gone home.
