題目精析

選項(xiàng)：

A) absorb ??????? n./v.???????????????????????????? I) heights??? n.

B) combined???? v.??????????????????????????????? J) indifferent?? adj.

C) contribute?? ?? v. ????? ??????????????????????????? K) levels?? n.

來跟著小編一題一題地過一遍~? 看下如何解題噠~

The ocean is heating up. That’s the conclusion of a new study that finds that Earth’s oceans now ____26___ heat at twice the rate they did 18 years ago. Around half of ocean heat intake since 1865 has taken place since 1997, researchers report online in Nature Climate Change.

開篇第一句點(diǎn)明主旨：海洋正在升溫。第二句指出這是某某研究剛剛得出的新結(jié)論。第二句比較長(zhǎng)，結(jié)構(gòu)復(fù)雜。

不過做題時(shí)不用知道that后引導(dǎo)的從句是什么句子，只需要判斷空格處缺失的是什么成分。oceans 主語，now副詞，表明時(shí)態(tài)是現(xiàn)在，heat名詞，應(yīng)該是賓語，這里缺少動(dòng)詞。

oceans是復(fù)數(shù)主語，這里要填入的不是以s結(jié)尾的詞，也不是ed結(jié)尾的過去式。帶著這些推斷，去選項(xiàng)中尋找符合條件的答案：排除combined,mixed,結(jié)合語義，最后鎖定absorb。（26）A?? absorb

接著看第27空。

選項(xiàng)：

A) absorb ??????? n./v.???????????????????????????? I) heights??? n.

B) combined???? v.??????????????????????????????? J) indifferent?? adj.

C) contribute?? ?? v. ????????????????????????????????? K) levels?? n.

D) depth ???????? n.????????????????????????????????? ??????? L) mixed??? v.

E) emissions????????????? n.??????????????????????? M) picture?? n.

F) excursion????? n.?????????????????????????????? N) unsure?? adj.

G) explore???????? n./v. ??????????????????????????????????? O) voyage?? n.

H) floor??? n.

Warming waters are known to ___27___ to coral bleaching（珊瑚白化)and they take up more space than cooler waters, raising sea ____28___. While the top of the ocean is well studied, its depths are more difficult to ____29____.

分析完第26題，這道題就順理成章啦。不定式to后面跟動(dòng)詞原形，符合條件的就剩下contribute和explore了~?

這個(gè)詞還要跟to能搭配，結(jié)合句意，溫暖的海水導(dǎo)致珊瑚白化。（27）C?? contribute

第28空，考的不是英語，是常識(shí)。they相較于冷水占用的空間更多，那么什么上升了？顯然是海平面，水多了，海平面就上升了。這里填入levels。（28）K?? level

第29空，同理to后面跟動(dòng)詞原形，符合條件的就剩下explore了。節(jié)省時(shí)間趕緊做下一題。（29）G?? explore

發(fā)現(xiàn)規(guī)律了嗎？分析第一個(gè)可能要費(fèi)一些時(shí)間，但是只要標(biāo)注好詞性，確定好同類空（比如要填入動(dòng)詞的3個(gè)空）的第一個(gè)空填什么，同類的只要排除就OK啦！

選項(xiàng)：

A) absorb ??????? n./v.???????????????????????????? I) heights??? n.

B) combined???? v.??????????????????????????????? J) indifferent?? adj.

C) contribute?? ?? v. ????????????????????????????????? K) levels?? n.

D) depth ???????? n.????????????????????????????????? ??????? L) mixed??? v.

E) emissions????????????? n.??????????????????????? M) picture?? n.

F) excursion????? n.?????????????????????????????? N) unsure?? adj.

G) explore???????? n./v. ??????????????????????????????????? O) voyage?? n.

H) floor??? n.

The researchers gathered 150 years of ocean temperature data in order to get a better ____30____ of heat absorption from surface to seabed. They gathered together temperature readings collected by everything from a 19th century ____31___ of British naval ships to modern automated ocean probes.

第30空根據(jù)a + adj. +空格+of 結(jié)構(gòu)，判定這里缺名詞。而經(jīng)過剛剛做題，8個(gè)名詞剩下了6個(gè)，結(jié)合語義來選吧~

“研究者們搜集了海洋150年來的溫度數(shù)據(jù)，是為了更好地—— 吸收熱量blabla”。這里選picuture。get the picture：明白; 理解? （30）M picture

第31題，還是考查同樣的結(jié)構(gòu)，a + n. +空格+of 結(jié)構(gòu)；不過這里“19世紀(jì)”名詞修飾空格處的名詞；結(jié)合語義，符合的只有voyage和excursion。

進(jìn)一步排除，excursion遠(yuǎn)足；voyage 航行，多指海上的。（31）O?? voyage

選項(xiàng)：

A) absorb ??????? n./v.???????????????????????????? I) heights??? n.

B) combined???? v.??????????????????????????????? J) indifferent?? adj.

C) contribute?? ?? v. ????????????????????????????????? K) levels?? n.

D) depth ???????? n.????????????????????????????????? ??????? L) mixed??? v.

E) emissions????????????? n.??????????????????????? M) picture?? n.

F) excursion????? n.?????????????????????????????? N) unsure?? adj.

G) explore???????? n./v. ??????????????????????????????????? O) voyage?? n.

H) floor??? n.

The extensive data sources, ___32_____ with computer simulations(計(jì)算機(jī)模擬), created a timeline of ocean temperature changes, including cooling from volcanic outbreaks and warming from fossil fuel ____33____.

32空缺一個(gè)跟with搭配的非謂語動(dòng)詞（ing或ed結(jié)構(gòu)），符合條件的只有mixed或combined，結(jié)合句義，數(shù)據(jù)是結(jié)合了計(jì)算機(jī)模擬，選（32）B?? combined。

33空看起來單詞都不認(rèn)識(shí)。不要慌！可以通過結(jié)構(gòu)來判斷！and并列結(jié)構(gòu)空格處應(yīng)該是一個(gè)跟outbreaks并列的復(fù)數(shù)名詞，符合條件的只有emissions。（33）E?? emission

選項(xiàng)：

A) absorb ??????? n./v.???????????????????????????? I) heights??? n.

B) combined???? v.??????????????????????????????? J) indifferent?? adj.

C) contribute?? ?? v. ????????????????????????????????? K) levels?? n.

D) depth ???????? n.????????????????????????????????? ??????? L) mixed??? v.

E) emissions????????????? n.??????????????????????? M) picture?? n.

F) excursion????? n.?????????????????????????????? N) unsure?? adj.

G) explore???????? n./v. ??????????????????????????????????? O) voyage?? n.

H) floor??? n.

About 35 percent of the heat taken in by the oceans during the industrial era now resides at a ___34____ of more than 700 meters, the researchers found. They say they’re ___35___ whether the deepsea warming canceled out warming at the sea’s surface.

34空，at a 空格+ of 結(jié)構(gòu)簡(jiǎn)直是出題老師的最愛啊，空格處缺的仍然是名詞，結(jié)合后面的700 meters，和海洋的語境，這里不可能是heights高度，而是depth深度。

（34）D?? depth

35空這里系表結(jié)構(gòu)，缺少形容詞，一共2個(gè)adj。結(jié)合語義排除掉indifferent，一般說明文科學(xué)家的態(tài)度或?qū)δ呈碌目捶ú粫?huì)是“冷漠的”，而是“不確定”。（35）N?? unsure

總結(jié)一下：《海洋在升溫》反復(fù)考到的結(jié)構(gòu)是：

1. a +adj./n.+空格（n.）結(jié)構(gòu)；【3次】

2. to動(dòng)詞不定式+動(dòng)詞原形 【2次】

3. and連接的并列結(jié)構(gòu)；

3. 固定搭配：

contribute to：有助于；導(dǎo)致

combine with：和……結(jié)合

get the picture：明白; 理解
