一些想法和查到的資料想和大家討論 ※ 引述《invisibleya (inv)》之銘言： : 1. Nutritionists recommend that each individual take sufficient amounts : of vitamin C so that may he may not contract svurvy as well as other : diseases attributed to the lack of the nutrient. : 第一行中的take是否應該要用第三人稱單數 即takes 文法書中多半會提到下面幾個動詞用法有些特別： ┌ suggest ┐ │ propose │ ┌ should + infinitive 其句型是 S + │recommend│ + (that) + S + │ infinitive │ insist │ └ V (past form) └ demand ┘ [the subjunctive] -----------------可以跳過----------------- The subjunctive mood is a verb mood typically used in dependent clauses to express a wish, emotion, possibility, judgment, opinion, necessity, or action that has not yet occurred. (from Wikipedia) [to own] [to be] Present I own I am indicative he/she/it owns he/she/it is we/you/they own we/you/they are Present I own I be subjunctive he/she/it own he/she/it be we/you/they own we/you/they be Past I owned I was indicative he/she/it owned he/she/it was we/you/they owned we/you/they ware Past I owned I were subjunctive he/she/it owned he/she/it were we/you/they owned we/you/they were Future I will/shall own I will/shall be indicative he/she/it will own he/she/it will be we/you/they will/shall own we/you/they will be Future I were to own I were to be subjunctive he/she/it were to own he/she/it were to be we/you/they were to own we/you/they were to be -----------------可以跳過----------------- 所以題目中的take不需用takes 但我沒看到書上說這些動詞不允許用一般的that clause形式，也就是你寫的這個問題 不過我也沒看過說可以用的說法就是了，另外會有文法的題目將 -s 的選項視作錯的 補充一下，後面也不能 + somebody to do something，不像ask, tell 好像文法中也常考這個規則，但我也沒在書上看到為什麼不能用 另外suggestion/proposal/recommendation important/vital/necessary/essential/desirable/imperative 後面也可以用that (should) infinitive的形式 例：What do you think of Jane's suggestion that I should buy a car? It's essential that you should be here on time. : 2. Historians are still mystified by the question how some ancient : civiliztions disappeared suddenly in history. : 第一行中的how為何不能使用why 這題是選項一個用how開頭，另一個用why起始嗎？ 我自己是覺得這個的句子將how改成why意思僅改變一些 而且不管那些historians問how~或why~，簡單回答起來都差不多 : 3. __________, the cell bodies that control the heredity of an animal or : a plant. : (A) DNA is the chief material in chromosomes : (B) The chief material in chromosomes is DNA : (C) In chromosomes DNA is the chief material : (D) In chromosomes the chief material is DNA : 正確答案是A 想請問其他選項為何不行 這題除了問英文用法，也是考科學的想法吧 XD 就comma後面的敘述你覺得是指chromosome還是DNA 選擇那一個就將那個字放在comma前面 這個用法和平常說的同位語、關係代名詞的restrictive clause都是用來做為補充說明 會將要說明的該對象置於comma前 另外如果你能接受後面那個是指DNA的話，也就是將DNA放在comma前面 那(B)和(D)都可以了，但單複數需修正，而要用(C)的話，可以改成 In chromosomes DNA is the chief material that controls the heredity of ... 但就意思上到底是chromosome對，還是DNA，我覺得爭這個是沒多大意義就是了 --
