參考答案：
1.正確答案：B
答案解析：句子意思為“科學家能注意到大多數人注意不到的許多事物”。
2.正確答案：C
答案解析：空格前后句子的意思是相反的，由此可知空格處應該用一個表示轉折的詞。in spite of是介詞短語，后面不能跟從句;despite是介詞，也不能引導從句。in that意思是“既然，因為”，不符合句意。所以只有C項正確。句意：她通過了考試，雖然她沒怎么用功。
3.正確答案：B
答案解析：句中用了but，表示轉折，所以A答案錯誤。either表示“(兩個中的)一個”，也不符合句意。neither表示兩者都不，符合句意。none是指三者以上的人或物，而句子中說的是the twins，是兩個人，所以也不正確。句意：父親希望這對雙胞胎成為醫生，但他們沒有一人喜歡學醫。
4.正確答案：D
答案解析：as if引導的是與現在事實相反的虛擬。
5.正確答案：B
答案解析：at the price of是固定搭配，意思是：以…的價錢。
參考答案：
6.正確答案：A
答案解析：表述永恒的真理或客觀規律用一般現在時，不管主句謂語用什么時態。而“地球繞著太陽轉”是客觀規律，所以選A.
7.正確答案：C
答案解析：reluctant“不愿的，勉強的”：“他非常不愿意去，但他別無選擇”，所以，reluctant用于本句合適。Hesitant“躊躇的，猶豫的”;ready“準備好的”;willing“愿意的”。
8.正確答案：A
答案解析：以分數限定的名詞做主語時，謂語的單復數應同該名詞保持一致，而不管分數是單數還是復數。此句中property(財產)是不可數名詞，故用單數形式的動詞。
9.正確答案：C
答案解析：nothing…more than是習慣用語，意思為“什么也比不上…更…”。句子意思為：記住，什么也比不上讀得太慢更傷害注意力的集中了。
10.正確答案：B
答案解析：本句是帶有不定式短語作目的狀語的簡單句。句意為“許多人都投入了身體鍛煉計劃，以保持良好的健康”。make a commitment“投入，保證”符合題意。
11.正確答案：B
答案解析：similar常與to搭配，所以答案是B.
12.正確答案：A
答案解析：in case：以防。
13.正確答案：B

14.正確答案：C
答案解析：形容“雨大”用heavily.句意：雨下得很大。我們只好待在家里，不能去釣魚了。
15.正確答案：C
答案解析：that做主語從句he speaks softly的引導詞，沒有實際意義。
16.正確答案：B
答案解析：can‘t have done，表示對過去發生情況的否定推測，意為“不可能已經……”。
17.正確答案：B
答案解析：Let‘s do sth.表示“建議做某事”，含聽話一方在內，故用 shall we.如果用Let us do sth.結構，則用will you?表示請求對方允許。
18.正確答案：A
答案解析：needn‘t表示“不必要”;mustn’t表示“禁止”;wouldn‘t表示“拒絕”。
19.正確答案：D
答案解析：句子意思為“到目前為止，關于夢游病原因有多種說法”。“關于”用as to，其他in view of “考慮到，由于”;in line with“符合”; apart from“除去”，意思不符合。
20.正確答案：D
答案解析：remind sb of sth是固定搭配，意思是：提醒某人某事。
