登入後即可作答並保存紀錄。
本題考查詞性的判斷。
題目句子的結構是 "A research institute offers staffs ____ which include a pension plan."
"which include a pension plan" 是關係代名詞子句,用來修飾前面的名詞。
"offers staffs ____" 表示研究所提供給員工的「東西」。這個「東西」應該是一個名詞。
選項 (A) "benefits" 是名詞,意為「福利」。
第 4 題2 分
She could not sit in an aisle seat during her bus trip because there were ____ available.
(A) some
(B) any
(C) mainly
(D) none
(E) more
登入後即可作答並保存紀錄。
核心觀念
本題考查:
- 不定代名詞的用法:
some、any、none - 否定語意與代替名詞的功能
available作後置修飾語的用法
句意為:
她搭公車時無法坐在靠走道的座位,因為沒有任何座位是可提供的。
其中 none 代替前文提到的 aisle seats,完整意思是:
there were none available
= there were no aisle seats available
none 本身表示「沒有一個/沒有任何一個」,可單獨作代名詞使用。
解題方法
先觀察因果關係:
She could not sit in an aisle seat ... because ...
前句表示「她無法坐靠走道的座位」,因此後面的原因應表達「靠走道的座位一個也沒有」。
空格後的 available 是形容詞,修飾被省略的名詞 aisle seats。因此句型可還原為:
there were no aisle seats available.
將 no aisle seats 改用代名詞代替,即為:
there were none available.
所以正確答案是 (D) none。
選項分析
(A) some
some 表示「一些」,通常用於肯定句:
There were some seats available.
有一些座位可以使用。
若填入句中:
She could not sit in an aisle seat because there were some available.
意思變成「因為有一些靠走道座位可以使用」,與前句「無法坐靠走道座位」的原因矛盾,因此錯誤。
(B) any
any 常用於疑問句、否定句或條件句,例如:
Are there any seats available?
有任何座位可以使用嗎?
There weren’t any seats available.
沒有任何座位可以使用。
本題空格所在的子句是:
第 5 題2 分
Transport officials were unsure of ____ caused the airplane crash in this night.
(A) why
(B) what
(C) where
(D) those
(E) each
登入後即可作答並保存紀錄。
本題考查疑問詞在名詞子句中的用法。
題目句子的結構是 "Transport officials were unsure of ____ caused the airplane crash in this night."
"unsure of" 後面需要接一個名詞子句,作為介系詞 "of" 的受詞。
這個名詞子句的開頭應該是疑問詞,用來引導關於「飛機墜毀的原因」。
選項 (A) "why" 是疑問副詞,用來詢問原因。
第 6 題2 分

They ____ to fill in the forms for agreements.
(A) remind
(B) have reminded
(C) reminding
(D) are reminding
(E) are reminded
登入後即可作答並保存紀錄。
本題考查動詞的時態與語態。
題目句子的結構是 "They ____ to fill in the forms for agreements."
這裡的 "They" 指的是某一群人。
"to fill in the forms" 是不定詞片語,表示「填寫表格」。
考慮到語意,通常是有人「被提醒」去填寫表格,而不是他們主動「提醒」別人填寫表格。
選項 (A) "remind" 是現在式動詞,主詞是複數。
第 8 題2 分
Researchers looking for good papers will find a ____ selection in the special issues.
(A) greater
(B) greatest
(C) greatly
(D) more greatly
(E) greaten
登入後即可作答並保存紀錄。
核心觀念
本題考查「形容詞在名詞前作修飾語」以及比較級的用法。
句型為:
a + 形容詞 + 名詞
空格後的名詞是 selection,因此空格必須填入能修飾名詞的形容詞。greater 是 great 的比較級,具有「更大的、更多的、更優良的」之意。
a greater selection 可解釋為「更多樣、更豐富的選擇」,暗示特刊中的論文選擇比一般期刊或其他刊物更豐富。
解題方法
先觀察空格位置:
空格位於冠詞 a 與名詞 selection 之間,應填入形容詞。
完整句意為:
尋找優良論文的研究人員,會在特刊中找到更豐富的選擇。
greater 是形容詞,可直接放在名詞 selection 前:
a greater selection
更豐富的選擇
因此正確答案為 (A) greater。
選項分析
-
(A) greater:正確
greater是great的比較級,屬於形容詞,可修飾名詞selection。a greater selection表示「更豐富的選擇」,語意符合特刊通常集中優良論文的上下文。 -
(B) greatest:錯誤
greatest是最高級形容詞,表示「最大的、最優良的」。最高級前通常搭配定冠詞the:the greatest selection

In contrast, the nanochannels in (B)-(E) exhibit approximately rectangular shapes. With increases in the exposure time, the nanochannels also became wider, and the optimal exposure time was determined to be 0.5 µs/dot. Using this exposure, nanochannels with dimensions of 48 ± 3 nm (width) and 49 ± 1 nm (depth) with approximately square shapes were obtained.」
