      中華考試網(wǎng)   2016-10-06   【

        1. When ---in arctic regions, the Aleuts construct igloos as temporary winter shelters.

        (A) travel

        (B) to travel

        (C) traveling them

        (D) traveling

        答案:D

        測試點:省略句。

        分析:引導(dǎo)狀語成分的連詞when可后接從句或亦可接分詞。When+分詞短語相當(dāng)于從句省掉了主語和系詞,即when(the Aleuts are)traveling in arctic legions.(A)動詞原形和(B)不定式均不可與when連用作狀語;(C)多了them.

        解題要點:時間狀語從句的連詞(when,while)后可直接加分詞短語。條件是這一從句的主語應(yīng)與主句的主語同一人/物。

        2. Most substances contract when they freeze so that the density of a substance’s solid is ---of its liquid.

        (A) than the higher density

        (B) higher than the density

        (C) the density is higher than that

        (D) the higher the density

        答案:B

        測試點:比較級/詞序.

        分析:比較級的句式要求動詞+形容詞或副詞比較級+than+被比較的成份,4個答案中只有(B)符合此結(jié)構(gòu).

        3. The mechanism by which brain cells store memories is ---clearly understood.

        (A) none

        (B) no

        (C) not

        (D) nor

        答案:C

        測試點:否定詞.

        分析:否定動詞要用副詞not.

        4. Desert animals ---a means of retaining moisture in such a hot, dry climate if they are to survive.

        (A) need

        (B) needing

        (C) to need

        (D) was needed

        答案:A

        測試點:謂語.

        分析:空格兩邊都是名詞性成份,說明所缺為謂語動詞.答案中(A)可作謂語.(B)(C)不能單獨作謂語;(D)用了被動式,與句意不合。

        5. ---state of Wyoming is also known as the “Equality State” because Wyoming women were the first in the nation to vote.

        (A) The

        (B) There is a

        (C) That the

        (D) As the

        答案:A

        測試點:冠詞.

        分析:空格后是一完整的復(fù)合句,空格內(nèi)不可能填入帶有連詞或動詞成分的(B)、(C)或(D).這里缺少的是限定state of Wyoming的定冠詞the.

        6. Fructose is a monosaccharide sugar that is much sweeter ---.

        (A) than cane sugar does

        (B) does cane sugar

        (C) cane sugar

        (D) than cane sugar

        答案:D

        測試點:比較句式.

        分析:看到比較級的sweeter一詞,就應(yīng)在答案中尋找以than開頭的形式,即(A)和(D).(A)中動詞does與比較級前半部分系詞不一致,而答案(D)是省略了系詞is.的正確形式.

        解題要點;比較級結(jié)構(gòu)要求前后比較的兩部分句子結(jié)構(gòu)一樣,應(yīng)然,助動詞(do,does,did)及系詞(be)在后半部分可以省略.

        7. Ground plans and contour maps of the Earth ---from aerial photographs.

        (A) can be drawn

        (B) can draw

        (C) to draw

        (D) drawn

        答案:A

        測試點:謂語/被動語態(tài).

        分析:空格前是名詞性成份,所缺為謂語動詞.空格后有from短語,說明謂語動詞應(yīng)為被動態(tài),故選(A).(B)為主動態(tài);(C)(D)都是動詞的非謂語形式分詞,前缺助動詞.

        解題要點:空格后出現(xiàn)from或by的短語,動詞常常是被動態(tài).

        8. By the middle of the twentieth century, painters and sculptors in the United States had begun to exert ---over art.

        (A) influence worldwide a great

        (B) a great worldwide influence

        (C) influence a great worldwide

        (D) a worldwide influence

        答案:B

        測試點:詞序。

        分析:exert的賓語應(yīng)是名詞influence,應(yīng)在答案中分辨哪個是以influence為中心詞的詞,即(B).

        解題要點;多個形容詞修飾名詞時詞序排列是有規(guī)律的.其中心詞名詞位置一般在最后,冠詞在最前面.其間的多個形容詞則依與中心名詞的修飾關(guān)系的強弱而從后往前排列.此句首先強調(diào)的是一個全球性的影響(world wide influence)然后再說明這個“全球性影響”是巨大的(agreat worldwide influencc).

        9. ---millions of galaxies exist in the vast space outside the Milky Way.

        (A) It is estimated that

        (B) An estimate that

        (C) That is estimated

        (D) That the estimated

        答案:A

        測試點:形式主語/復(fù)合句。

        分析:空格后為完整的句子,空格前可能是短語或句子。(B)(D)都是不完整的結(jié)構(gòu);(C)與后文之間無連詞,故選(A).It是形式主語,that后的從句才是真正的主語.

        10. The extent of the harmful effect of locoweeds on animals depends on the soil ---the plants grow.

        (A) which

        (B) which in

        (C) in which

        (D) in

        答案:C

        測試點:介詞+which結(jié)構(gòu).

        分析:空格后為主謂完整的定語從句.In which=where(介詞+關(guān)系代詞=關(guān)系副詞),用來修飾先行詞soil,表示地點.

        解題要點:關(guān)系代詞which在賓語從句中,應(yīng)承擔(dān)其主語或賓語的身份.如從句中主語、賓語俱全(或如此句grow為不及物動詞,無需有賓語),則應(yīng)考慮用關(guān)系副詞,或其變形介詞+which。此形式為TOEFL?碱}型。

        11. The operetta first ---as a popular form of musical theater in the nineteenth century.

        (A) to emerge

        (B) emerging

        (C) has emerged

        (D) emerged

        答案:D

        測試點:謂語.

        分析:句中缺謂語動詞,而(A)(B)都是動詞的非謂語形式,不可單獨作謂語.(C)是完成時,不能與副詞first搭配,故選(D).

        12. ---complex organic catalysts originating in living cells.

        (A) Enzymes

        (B) Enzymes are

        (C) Enzymes which are

        (D) Enzymes while they

        答案:B

        測試點:主謂結(jié)構(gòu).

        分析:句子主、謂均缺,應(yīng)在答案中選擇主語+動詞的形式,即(B).(A)無動詞;(C)(D)含有從句.

        13. In the eastern part of New Jersey ---, a major shipping and manufacturing center.

        (A) lies the city of Elizabeth

        (B) the city of Elizabeth lies there

        (C) around the city of Elizabeth lies

        (D) there lies the city of Elizabeth around

        答案:A

        測試點:倒裝句。

        分析:表示地點的介詞短語放在句首,通常后面的句子要倒裝。應(yīng)在答案中選擇動詞+名詞的形式,即(A).

        解題要點;遇到倒裝句,在4個答案中尋找以動詞開頭的形式.

        14. Work in parapsychology, ---, has attracted a relatively small number of scientists.

        (A) is a very controversial field

        (B) which a very controversial field is

        (C) a very controversial field

        (D) a field very controversial which

        答案:C

        測試點:同位語.

        分析:主語后面的空格,兩邊用逗號隔開,常常要么是分詞短語作定語,要么是同位語.應(yīng)在答案中選擇說明主語性質(zhì)的名詞性結(jié)構(gòu)作其同位語,即(C).(A)多了動詞;(B)(D)與從句有關(guān).

        15. ---, the constitution of the Cherokee Nation provided for a chief executive, a senate, and a house of representatives.

        (A) In 1827 they drafted

        (B) The draft in 1827

        (C) In 1827 was drafted

        (D) Drafted in 1827
