你知道現(xiàn)在能否去學(xué)校嗎？④后跟or not時(shí)。如：I'm not sure whether or not the shop is open. 我不確定商店是否在營(yíng)業(yè)。⑤作介詞的賓語(yǔ)或動(dòng)詞discuss的賓語(yǔ)時(shí)。如： It depends on whether it will be fine. 這要看天氣是否會(huì)好。We discussed whether we should use the money to buy a new house.我們討論了是否應(yīng)該用這筆錢買一所新房子。4. so...that...和such...that...(1)so...that...中的so是副詞，其后只能跟形容詞或副詞；而such...that...中的such是形容詞，后接名詞或名詞短語(yǔ)。如：He was so careless that he forgot to write his name on the paper.他太粗心了，以至于忘記在紙上寫他的名字。Dalian is such a beautiful city that a great many people go there for holidays.大連是一個(gè)如此美麗的城市，許多人去那里度假。(2)名詞前有many、 much、 little、 few時(shí)用so，不用such。如：I have had so many falls that I am black and blue all over.我摔了那么多跤，以至于我全身青一塊紫一塊。5. either...or...、 neither...nor...和not only...but also...這三個(gè)連詞詞組都可連接兩個(gè)并列成分。當(dāng)它們連接兩個(gè)并列主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞要隨相鄰的主語(yǔ)變化。Either my father or my brothers are coming.不是我父親就是我兄弟要來(lái)。(近brothers用are)Neither her parents nor she was at home. 她父母和她都不在家。(近she用was)6. though/although和butalthough和though表示“雖然”，兩者同義，可互換。although比though更為正式。though引導(dǎo)讓步狀語(yǔ)從句時(shí)，從句中的表語(yǔ)、狀語(yǔ)、實(shí)義動(dòng)詞等可以提前，但although不能這樣用。though還可以作副詞，表示“不過(guò)，可是”，放在句末，前有逗號(hào)隔開(kāi)。尤其需要注意的是，though/although和but不能同時(shí)出現(xiàn)在一個(gè)句子里，但可以與yet、 still連用。如：Although he is over sixty, but he works as hard as others. (×)Although he is over sixty, he works as hard as others.＝He is over sixty, but he works as hard as others.雖然他已經(jīng)六十多歲了，但他還像其他人一樣努力工作。7. because和so這兩個(gè)連詞同樣不能用在同一個(gè)句子中。如：Because John was ill, so I took him to the doctor. (×)Because John was ill, I took him to the doctor.＝John was ill, so I took him to the doctor.因?yàn)榧s翰生病了，所以我?guī)タ瘁t(yī)生。【例1】　(2024年甘肅省分類考試)The children were very excited these days ________ they were preparing for the New Year.(　　) A. because B. if C. when D. so 例1例3【解析】　句義：“這些天孩子們非常興奮，因?yàn)樗麄冋跒樾履曜鰷?zhǔn)備?！备鶕?jù)句義可知答案。故選A。A例2例4例5例6【例2】　(2024年甘肅省分類考試)He gets up early ________ he can catch the first bus to company.(　　) A. so that B. in order to C. what D. which【解析】　句義：“他早起以便能趕上最早的公交車去公司?！备鶕?jù)句義可排除C、D兩項(xiàng)；in order to后跟動(dòng)詞(短語(yǔ))，so that后跟句子。故選A。A例1例3例2例4例5例6【例3】　(2023年甘肅省分類考試)My dear boy, be quick! ________ we will miss the early bus.(　　) A.
