這篇筆記: 最容易中文直翻的介係詞與動詞搭配、if 條件句的三種句型、主詞一長就忘記的主詞動詞一致,以及論點和事件的時態。

最常被改的文法錯誤|共 3 篇

  1. 1. 為什麼卡關、單複數與冠詞
  2. 2. 介係詞、if 句與主詞動詞一致(你正在讀)
  3. 3. 逗點串句與檢查清單

四、介係詞與動詞搭配:最容易「中文直翻」的地方

介係詞的錯幾乎都來自中文直翻:「在職場上」就寫 on the workplace、「在這個星球上」就寫 in this planet。我的筆記裡有一整頁「不是 X,是 Y」的對照,整理如下:

正確說法我曾經寫成中文意思/記法
in the workplaceon the workplace職場被想成一個「空間」,用 in
on this planetin this planet在地球「表面」上,用 on
in the entertainment industryon entertainment industries在某個產業裡
on a regular basis / on a daily basison a regular basic、on daily basic是 basis(基礎)不是 basic(基本的),前面要 a
put emphasis onput emphasis(漏 on)emphasis 是名詞,需要 on 接受詞
overemphasize +受詞(不加介係詞)overemphasize on appearance(Task 25)emphasize 是及物動詞,直接接受詞
search for informationsearch the functionssearch X 是「搜查 X 這個地方」,找東西要 search for
the information in advertisementsinformation on advertisement內容「在」廣告裡
distract sb from sthdistract sb to從某事分心
major contributors tomajor contributors incontribute to 的名詞也是 to
concentrate on / focus onconcentrate in專注「在」某事上
deprive A of B—剝奪 A 的 B(depriving them of the chance to…)
be allocated to studyingbe assigned to study這裡的 to 是介係詞,後面接 V-ing
pay attention to + V-ingpay attention to study同上,to 是介係詞
pose a threat topost a threat on / pose a threat on是 pose 不是 post;threat 接 to
benefit from free entrance to museumsfree entrance of museums進入某地方用 entrance to
the demand for each productthe demand of each productdemand for 需求
residents of a number of nationsresidents from…某地的居民
face uncertainty(不加 with)face with the uncertainty(Task 23)face 當動詞直接接受詞;be faced with 才有 with
help sb do sthhelp them to find不是錯,但 help 後直接接原形更自然、更省字

另外兩個我很常混淆的組合也一起記:result in(導致,後面接結果)vs. result from(源自,後面接原因);take X into consideration(不是 put X into consideration)。

五、if 條件句:三種句型與我寫錯的地方

if 條件句在大作文很好用,可以寫「如果政府這樣做,就會…」的推論。我筆記裡整理了三種常用句型:

類型句型例句什麼時候用
真實條件(最常用)If + S + 現在式, S + will + VIf the government raises taxes on sugary drinks, consumption will probably fall.大作文推論「政策的可能結果」,九成情況用這個
與現在事實相反If + S + 過去式, S + would + VIf I were rich, I would travel around the world.假設不太可能發生的狀況
與過去事實相反If + S + had + p.p., S + would have + p.p.If I had studied harder, I would have passed the exam.用個人經驗舉例:「要不是當年…,我就會…」

第三種句型是我舉個人例子時用的。我在一篇關於「政府經費應不應該只給理科」的作文裡,就用了這個句型,大意是「如果當時政府沒有平等補助各科,我就只能放棄夢想」,結構是 I would have been forced to give up my dream if … had not been …,前後時態都對上了。下面用同樣的骨架寫一句示範:

示範:I would have had to abandon my plan to study abroad if I had not received a government scholarship.

我在 if 句裡真正犯的錯:if 子句少了 be 動詞

我寫的(✗)改法(✓)
✗ if they unable to earn money from visitors(Task 21)✓ if they are unable to earn money from visitors
✗ if we willing to try newer or dangerous things✓ if we are willing to try new or dangerous things
✗ If workers enable to spend quality holiday✓ If workers are able to spend quality holidays
✗ If the government rises the petrol price✓ If the government raises the petrol price

前兩句是同一個毛病:形容詞(unable、willing)不能自己當動詞,前面一定要有 be 動詞;第三句則是把動詞 enable 和形容詞 able 搞混。第四句是 rise / raise 混用:rise 是不及物(價格自己上升),raise 是及物(政府「把」價格調高)。

六、主詞動詞一致:主詞一長就忘記

主詞動詞一致(subject–verb agreement)在我的作文裡最常出現在兩種情況:主詞很長,或主詞是動名詞。訣竅是找出主詞裡真正的「頭」,把修飾語都先遮起來。

主詞動詞一致錯句與改法對照:五個真實錯句、真正的主詞與正確動詞,例如 Advertisements is 改成 Advertisements are、taking risks grant 改成 taking risks grants
先遮掉修飾語找出主詞的「頭」,再決定動詞要不要加 s。
我寫的(✗)真正的主詞改法(✓)
✗ Advertisements is beneficial to some extent.(試改 3)Advertisements(複數)✓ Advertisements are beneficial
✗ if a person keep seeing an item’s picture(試改 3)a person(單數)✓ if a person keeps seeing
✗ A wide range of illness, especially mental diseases, are good examples(Task 7)illness → 改 illnesses✓ A wide range of illnesses … are good examples
✗ most of the information residents want to know are available(Task 17)information(不可數)✓ most of the information … is available
✗ taking risks grant people more opportunitiestaking risks(動名詞=單數)✓ taking risks grants
✗ Similarity, doing uncontrollable behaviors in our private life make us…doing…(動名詞=單數)✓ Similarly, behaving recklessly in our private lives makes us…
✗ having houses are so important for some Taiwanese peoplehaving houses(動名詞=單數)✓ owning a house is so important
✗ expenditure likes the salary … and maintenance cost is undoubtedly high(Task 21)expenses … and maintenance costs(複數)✓ expenses such as staff salaries and maintenance costs are high

還有一組要分清楚:a number of + 複數名詞 + 複數動詞(很多…);the number of + 複數名詞 + 單數動詞(…的數量)。例如 A number of students are…;The number of students is increasing.

句子缺動詞:比主詞動詞不一致更嚴重

有時候不是動詞形態錯,而是根本少了動詞,讀起來就是一個沒寫完的句子。這類錯誤在 GRA 6 的篇目裡特別多:

我寫的(✗)改法(✓)
✗ it is frequently been ignored(試改 3)✓ it is frequently ignored / it has frequently been ignored
✗ Those opposed to the usage of driverless vehicles due to the following two reasons.(Task 15)✓ Those who oppose driverless vehicles do so for two reasons.
✗ a number of sugary products still be sold in the markets(Task 7)✓ a number of sugary products will still be sold
✗ two types of jobs need to paid highly(Task 25)✓ two types of jobs need to be paid highly
✗ a city road, which located in the southern part(Task 19)✓ a city road, which was located in the south
✗ A hotel is replaced the castle(Task 33)✓ A hotel has replaced the castle / The castle has been replaced by a hotel
學姊提醒:被動語態的公式是「be + 過去分詞」,兩個零件缺一不可。我筆記裡寫的是:MODAL VERB(may / could / would)+ BE + PAST PARTICIPLE。寫到 will be sold、can be reduced、has been replaced 時,手指點一下 be 有沒有在。

七、時態:論點用現在式,事件用過去式

大作文的時態其實很單純:論點用現在簡單式(一般事實與看法),描述趨勢用現在完成式(has risen、has become),舉過去發生的具體事件用過去式。我會錯,通常是在舉例時寫著寫著跳回現在式。

我寫的(✗)改法(✓)說明
✗ Taiwanese factories lose the whole market share after Chinese rice has been imported.✓ Taiwanese factories lost their market share after Chinese rice was imported.在講已經發生的事,前後都用過去式
✗ most of small and median corporations do have ability to overcome the difficulties when the pandemic happened.(Task 23)✓ most small and medium-sized companies did not have the ability to overcome the difficulties when the pandemic hit.疫情是過去事件;而且原句漏了 not,意思整個相反
✗ To put it another way, children lost opportunities to enhance their social skills.✓ children lose opportunities to develop their social skills這裡是一般論點,用現在式
✗ In 2000, … there are two spaces for fishing boats and marina(Task 33)✓ In 2000, … there were two areas for fishing boats and a marina小作文地圖題的過去年份要用過去式

小作文地圖題特別要注意:過去的地圖用過去式,「現在」的地圖用現在式或現在完成式(has been replaced)。我的兩篇地圖題 GRA 都只有 6,時態和被動語態混亂是主因之一。
