TOEFL 的比較句陷阱:More Than、As Much As、Fewer Than、Compared With
Write for an Academic Discussion 剩五分鐘。你想乾淨地對比 reading 與 lecture。你打出:「The lecturer presents fewer evidence than the reading, and her conclusion is more clearer.」摘要其他部分都還可以,但兩個比較錯誤剛剛溜進來了——一個是可數 vs. 不可數的滑誤,一個是雙重比較。評分者兩個都注意到。分數停在 Band 4,沒能推到 Band 5。歡迎來到比較句陷阱:關於 more、fewer、as、than 的小選擇,承載的重量比你以為的還大。
比較句在 TOEFL iBT 2026 中無處不在。Write for an Academic Discussion 整個就是建在比較上。Take an Interview 與 Academic Discussion 嚴重依賴比較片語。Reading 文章不斷使用比較結構強調兩個理論、兩個時期或兩個方法之間的對比。而比較文法的規則比大多數學習者以為的還多。
為什麼這在 TOEFL iBT 2026 很重要
Write for an Academic Discussion 結構上就是一個比較任務。你在解釋 lecture 怎麼與 reading 相關——通常是挑戰它。每段至少含一個比較字:however, in contrast, more, fewer, less, the same as, similar to, unlike, whereas。每一個都需要正確結構才能乾淨落地。
Reading 中,比較訊號字引導推論。文章常說「Theory A explains X more comprehensively than Theory B」——而比較結構本身就是整個證據。如果你誤判方向,就漏掉推論。
Academic Discussion 中,把你的立場與先前學生的立場相比,是你能做的最有力動作之一:「While Emma focuses on cost, my main concern is access.」這句其實就是偽裝的比較。
Speaking 中,控制好的比較片語如「more efficient than」、「just as important as」、「fewer disruptions than」能把回答拉高,超越一般說法。口語英文容許較鬆的比較形式,但基本規則仍適用。
陷阱
比較文法在時間壓力下會以六種可預測的方式失敗。
More / fewer / less(可數 vs. 不可數)。 Fewer 配可數名詞——你可以數的東西:fewer students, fewer mistakes, fewer arguments。Less 配不可數名詞——你測量而非計數的東西:less water, less time, less evidence。「fewer evidence」是錯的,因為 evidence 在正式英文中是不可數名詞。同樣道理:fewer information, fewer research, fewer feedback——全部都該用 less。
雙重比較。 英文以兩種方式構成比較級:短形容詞加 -er(bigger, faster, clearer),長形容詞用 more(more important, more efficient, more comprehensive)。把兩者合起來就產生雙重比較:more bigger, more clearer, more faster。這些永遠是錯的。挑一種形式就好。
不完整比較。 比較級需要兩個東西在比。「This essay is more clear」立刻會引出疑問:比什麼更清楚?在時間壓力下,學習者經常把比較的另一半省掉,評分者只能用猜的。要嘛補完比較(「more clear than the first draft」),要嘛改寫成不用比較級(「This essay is clear」)。
As much as / as many as。 Much 配不可數名詞;many 配可數名詞。「She drinks as much coffee as her sister」(不可數)。「She solved as many problems as her sister」(可數)。混用——「as many coffee」或「as much problems」——是常見的失誤。
The same as / similar to / different from。 這三個片語在正式英文中有固定的介系詞。The same as,不是 the same with。Similar to,不是 similar with 或 similar than。Different from,不是 different with 或 different than(雖然 different than 在非正式美式英文中越來越被接受,different from 在 TOEFL 上是較安全的選擇)。
Compared with / compared to。 兩個都對,但在正式寫作中用法略有差異。Compared with 用於分析性對比:「Compared with traditional methods, the new approach is more efficient.」Compared to 用於類比:「Life can be compared to a journey.」在 TOEFL Writing 中做分析時,compared with 是較安全的正式選擇。
第七個議題:比較了錯誤的東西。 「The economy of Brazil is larger than France」把經濟與國家相比。正確比較是「The economy of Brazil is larger than that of France」或「The economy of Brazil is larger than the French economy」。不對等比較錯誤很細微,但會在 Write for an Academic Discussion 上扣分。
Wrong / Better / Why
| Wrong | Better | 為什麼 |
|---|---|---|
| The lecturer presents fewer evidence than the reading. | The lecturer presents less evidence than the reading. | Evidence 是不可數名詞——用 less,不是 fewer。 |
| The new method is more clearer than the old one. | The new method is clearer than the old one. | Clearer 已經是比較級;more clearer 是雙重比較。 |
| This essay is more developed. | This essay is more developed than my previous draft. | 比較級需要明示的比較對象。 |
| She solved as much problems as her classmate. | She solved as many problems as her classmate. | Problems 是可數名詞——用 as many。 |
| Online classes are similar with in-person classes in some ways. | Online classes are similar to in-person classes in some ways. | Similar 配介系詞 to,不是 with。 |
| The conclusion is different than the introduction suggests. | The conclusion is different from what the introduction suggests. | 正式 TOEFL 寫作偏好 different from。 |
| The population of Tokyo is larger than New York. | The population of Tokyo is larger than that of New York. | 用人口比人口,不是用人口比城市。 |
| She works more harder than anyone in the team. | She works harder than anyone in the team. | Harder 已經是比較級;加 more 是雙重。 |
哪裡會出現
Write for an Academic Discussion。 整個任務就是結構化的比較。每個主體段通常含一到兩個比較片語。這裡的錯誤特別顯眼,因為評分者就是要看你如何乾淨地表達 reading 與 lecture 之間的對比。像 less convincing than, in contrast with, similar to, compared with the reading 這類片語是這個任務的主力——而每一個都必須文法乾淨。
Reading 改寫題。 許多選項會打亂比較的方向。原文可能說「Theory A is more widely accepted than Theory B」,三個錯誤選項會翻轉方向或弱化比較。正確讀懂比較文法就是推論戰的一半。
Academic Discussion。 把你的立場與先前學生的立場相比是一個強動作:「My concern differs from Emma's in that…」或「Compared with Carlos's argument, my position emphasizes…」這些開頭能提升回答的感受複雜度。
Take an Interview。 短口說回答中一個控制好的比較能展現廣度:「Studying abroad is more valuable than online courses because…」避免堆形容詞或使用雙重比較——口語英文比較寬容,但評分者仍會注意到。

Fast Fix
三個檢查解決大部分比較錯誤。
第一,在寫 fewer 或 less 之前,問名詞是可數還是不可數。如果你可以在它前面放一個數字(three students, twelve mistakes, two arguments),用 fewer。如果不行(water, time, evidence, information, research),用 less。快速心測:「five _____」說得通嗎?通就是可數名詞。
第二,在用 more 加形容詞前,確認形容詞是否已經有 -er。Faster, clearer, easier, bigger, longer 已經是比較級。別再加 more。長形容詞(important, efficient, comprehensive, beneficial)不加 -er;用 more。兩個系統不可合用。
第三,把每個比較寫完整。每當你寫 more、less、fewer、bigger、clearer、better、worse,問:比什麼更 X?如果答案不在句子裡,補進去。即使是模糊的比較(「better than before」),也比沒比較好。
第四個檢查純粹是結構性的:確保你比的是相符的東西。人口比人口、經濟比經濟、reading 比 lecture(不要 reading 比 lecturer)。片語 that of——「the population of Tokyo is larger than that of New York」——是修不對等比較的正式修法。
小練習
- 修好可數/不可數錯誤:The lecturer has fewer evidence to support her claim.
- 修好雙重比較:This essay is more shorter than the first draft.
- 補完比較:The new approach is more efficient.
- 選對量詞:She made (as much / as many) mistakes as I did.
- 對齊被比較的東西:The climate of the desert is hotter than the coast.
可能的改進版本:(1) The lecturer has less evidence to support her claim. (2) This essay is shorter than the first draft. (3) The new approach is more efficient than the old method. (4) She made as many mistakes as I did. (5) The climate of the desert is hotter than that of the coast.
送出前要檢查什麼
在最後掃描時找三個模式。第一,視覺上搜尋 fewer、less、much、many:確認每一個都與所配名詞的可數/不可數狀態相符。第二,搜尋任何以 -er 結尾、前面有 more 的形容詞——這些是雙重比較,要把 more 刪掉。第三,搜尋每個 more、less、better、worse、bigger、clearer:確認附近有明示的比較對象。如果在比較級附近找不到「than X」或「compared with Y」,比較就不完整——補上缺的另一半或改寫成不用比較級。這三步掃描大概四十秒,能抓到把強回答安靜壓在 Band 5 以下的那些比較錯誤。
