[解析 ] A That’s后為表語從句，此處 where與downtown相呼應(yīng)，根據(jù)句意可排除其他選項(xiàng) 。 ? 22. It is none of your business other people think about you. Believe yourself. (2022 福建 ) A. how B. what C. which D. when ? [解析 ] B 該句中 it作形式主語， what引導(dǎo)主語從句。該主語從句還原為疑問句應(yīng)為“ What do other people think about you?”。 ? 23.

[解析 ] B 所填選項(xiàng)引導(dǎo)賓語從句，從句中不缺任何成份和意義，只缺少連接詞，所以用 that引導(dǎo)。 ? 24.

[解析 ] B of后為賓語從句，從句中缺少賓語，所以用 what引導(dǎo)； something后接定語從句，可以省略作賓語的關(guān)系詞 that。 ? 25. parents say and do has a lifelong effect on their children. (2022陜西 ) A. That B. Which C. What D. As ? [解析 ] C所填選項(xiàng)引導(dǎo)主語從句，且在從句中充當(dāng) say和do的賓語，可排除 A、 D兩項(xiàng)； which引導(dǎo)賓語從句時(shí)意為“哪一個(gè)”，表示選擇，與句意不符，故選 C。 ? 26. The traditional view is ______ we sleep because our brain is “programmed” to make us do so. （ 2022上海） ? A. when B. why C. whether D. that ? [解析 ] D is后為表語從句，從句中不缺任何成份和意義，只缺少連接詞，所以用 that引導(dǎo)。 ? 27. By improving reading skills, you can read faster and understand more of ______ you read. (2022上海春招 ) ? A. that B. what C. which D. whether ? [解析 ] B of后為賓語從句，從句中缺少賓語，可排除 A、D兩項(xiàng)； which引導(dǎo)賓語從句時(shí)意為“哪一個(gè)”，表示選擇，與句意不符，故選 B。 熱點(diǎn)分析 ? 一、連接詞 what與 that的用法區(qū)別。 ? 引導(dǎo)主、賓、表語從句時(shí)， what要充當(dāng)主語、賓語或表語等句子成分， that不作任何成分，只在語法上起連接的作用。例如 ? ____ we can’t get seems better than ____ we have. A. What。 what B. what。 that C. That。 that D. That。 what ? 解析：本句包含一個(gè)主語從句和一個(gè)賓語從句，且兩個(gè)從句都缺乏賓語，可見兩個(gè)引導(dǎo)詞都必須充當(dāng)成分，所以答案是 A。又如： ? ____ caused the accident is still a plete mystery. A. What B. That C. How D. Where ? 解析：該題答案是 A， what在主語從句中作主語，即作謂語動(dòng)詞 caused的執(zhí)行者。在下面的例句中， that不充當(dāng)任何成份，只起語法連接作用（因?yàn)榫渥颖旧聿蝗背煞郑?： That the former Iraq president Saddam was captured has been proved. ? 連接詞 whether和 if的用法區(qū)別。 ? 通常，引導(dǎo)主語從句、表語從句和引導(dǎo)同位語從句時(shí)，要用連詞 whether，不用 if；習(xí)慣上也只能說 whether or not，而不說 if …or not 。例如： ? ____ the 2022 Olympic Games will be held in Beijing is not known yet. A. Whenever B. If C. Whether D. That ? 解析：試題中的從句位于句首，不難知道這是一個(gè)主語從句，所以答案是 C。但是在賓語從句中表達(dá)“是否”既可用 if也可用 whether。 ? 名詞性從句的語序。 ? 與別的從句一樣，名詞性從句必須用陳述語序。例如 : ? No one can be sure ____ in a million years. A. what man will look like B. what will man look like C. man will look like what D. what look will man like ? 解析：由于從句不能倒裝，所以答案只能是 A。又如： ? You can’t imagine ____ when they received these nice Christmas presents. A. how they were excited B. how excited they were C. how excited were they D. they were how excited ? 解析：答案是 B。同時(shí)還須注意，從句的引導(dǎo)詞必須始終置于句首，而且 how和被修飾的詞 excited不能分裂開 。 ? 形式主語、形式賓語。 ? 當(dāng)主語從句較長，而謂語較短時(shí)，常常將從句后置，而用 it作為形式主語，置于句首。 ? 動(dòng)詞后接復(fù)合賓語，也可用 it作形式賓語。例如 : ____ is a fact that English is being accepted as an international language. ? A. There B. This C. That D. It ? 解析：所需詞至于句首，同時(shí)后面有 that從句（邏輯主語），可見這里應(yīng)該用形式主語 it,所以答案是 D。think, find, consider, believe, feel等動(dòng)詞后常帶復(fù)合賓語。例如： ? Many people think it possible that a trade war between EU and the States will happen. ? Who / whoever, what / whatever等的用法區(qū)別。 ? 一般說來， what/who等含特指意義，而 whatever/whoever等含泛指意義，意為“無論什么 /無論誰”。例如： ? It is generally considered unwise to give a child ____ he or she wants. ? A. however B. whatever C. whichever D. whenever ? 解析：答案是 B， whatever引導(dǎo)一個(gè)賓語從句，并且作 wants的賓語。這里的 whatever不能改成 what，因?yàn)轭}意想表達(dá)的顯然是“無論孩子要什么就給他 /她什么事不明智的”，具有泛指的概念。同時(shí)要注意，這里 whatever也不能改用 no matter what，因?yàn)楹笳咧荒芤龑?dǎo)狀語從句。又如： ? ____ has helped to save the drowning girl is worth praising. ? A. Who B. The one C. Anyone D. Whoever ? 解析：答案是 D， whoever意為“無論誰”，表泛指。比較下例： ? I can’t remember at the moment who has said the words. （這里的 who表特定的某人） ? Where, when, why等連接副詞引導(dǎo)的名詞性從句。 ? Where, when, why等連接副詞也可以引導(dǎo)名詞性從句，使用的關(guān)鍵是：這個(gè)詞必須符合句子的邏輯意義要求。例如： ? I drove to Zhuhai for the air show last week. ? Is that ____ you had a few days off? ? A. why B. when C. that D. where ? 解析：答案是 A， why引導(dǎo)的從句作表語，同時(shí) why在從句中作原因狀語。這里之所以選 why，而不是 when或 where等，唯一的依據(jù)便是句子的邏輯含義，及語境。又如（ MET94）； ? —Do you remember ____ he came? ? —Yes, I do, he came by car. ? A. How B. when C. that D. if ? 解析：答案是 A，從答語 “ he came by car”可知這里問的是“ he”來的方式，所以用 how引導(dǎo)。
