11.Copernicus maintained that the earth ______ round the sun. 【 A 】
A. moves
B. moved
C. moving
D. move
【答案解析】:表述永恒的真理或客觀規(guī)律用一般現(xiàn)在時(shí),不管主句謂語(yǔ)用什么時(shí)態(tài)。而“地球繞著太陽(yáng)轉(zhuǎn)”是客觀規(guī)律,所以選A.
12.He was very ______ to go,but he had no choice. 【 C 】
A. ready
B. willing
C. reluctant
D. hesitant
【答案解析】:reluctant“不愿的,勉強(qiáng)的”:“他非常不愿意去,但他別無(wú)選擇”,所以,reluctant用于本句合適。Hesitant“躊躇的,猶豫的”;ready“準(zhǔn)備好的”;willing“愿意的”。
13.Two-thirds of his property ______ lost in the fire. 【 A 】
A. was
B. were
C. are
D. have been
【答案解析】:以分?jǐn)?shù)限定的名詞做主語(yǔ)時(shí),謂語(yǔ)的單復(fù)數(shù)應(yīng)同該名詞保持一致,而不管分?jǐn)?shù)是單數(shù)還是復(fù)數(shù)。此句中property(財(cái)產(chǎn))是不可數(shù)名詞,故用單數(shù)形式的動(dòng)詞。
14.Remember, nothing hurts concentration ______ reading too slowly. 【 C 】
A. rather than
B. as well as
C. more than
D. instead of
【答案解析】:nothing…more than是習(xí)慣用語(yǔ),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。
15.Many people have made a ______ to a physical fitness program so as to maintain good health. 【 B 】
A. decision
B. commitment
C. contribution
D. difference
【答案解析】:本句是帶有不定式短語(yǔ)作目的狀語(yǔ)的簡(jiǎn)單句。句意為“許多人都投入了身體鍛煉計(jì)劃,以保持良好的健康”。make a commitment“投入,保證”符合題意。
16.Scientists could see many things that most people would ______ to see. 【 B 】
A. feel
B. fail
C. fall
D. fill

17.She passed the examination ______ she studied very little. 【 C 】
A. in spite of
B. despite
C. though
D. in that
【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(yīng)該用一個(gè)表示轉(zhuǎn)折的詞。in spite of是介詞短語(yǔ),后面不能跟從句;despite是介詞,也不能引導(dǎo)從句。in that意思是“既然,因?yàn)椤保环暇湟。所以只有C項(xiàng)正確。句意:她通過(guò)了考試,雖然她沒(méi)怎么用功。
18.The father wished the twins to be doctors, but ______ of them liked to study medicine. 【 B 】
A. both
B. neither
C. either
D. none
【答案解析】:句中用了but,表示轉(zhuǎn)折,所以A答案錯(cuò)誤。either表示“(兩個(gè)中的)一個(gè)”,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(shuō)的是the twins,是兩個(gè)人,所以也不正確。句意:父親希望這對(duì)雙胞胎成為醫(yī)生,但他們沒(méi)有一人喜歡學(xué)醫(yī)。
