參考答案:
1.正確答案:A
答案解析:表述永恒的真理或客觀規(guī)律用一般現在時,不管主句謂語用什么時態(tài)。而“地球繞著太陽轉”是客觀規(guī)律,所以選A.
2.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”。
3.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。
4.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。
5.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。
