【解析】

這是一篇說明文。根據(jù)最近的一項(xiàng)調(diào)查,超過70%的帝企鵝可能被上升的海洋溫度消滅。隨著它們賴以生存的魚類供應(yīng)進(jìn)一步進(jìn)入南大洋,情況可能會(huì)發(fā)生變化。魚類種群向南遷徙的影響可能導(dǎo)致企鵝種群大量減少。

1考查被動(dòng)語態(tài)。分析句子可知,設(shè)空處和could一起構(gòu)成句子謂語動(dòng)詞,主語king penguinswipe out之間是被動(dòng)關(guān)系,應(yīng)用被動(dòng)語態(tài),又情態(tài)動(dòng)詞could后要用動(dòng)詞原形,故填be wiped。

2考查副詞。句意:然而,很多人都很樂觀,因?yàn)檫@些統(tǒng)計(jì)數(shù)據(jù)顯示這些企鵝目前還沒有瀕臨滅絕,根據(jù)句意可知,上下文是轉(zhuǎn)折關(guān)系,故填However。

3考查名詞的數(shù)。分析句子可知,此處應(yīng)用名詞作為句子主語,因?yàn)榫渥訛橐话悻F(xiàn)在時(shí),故由謂語動(dòng)詞move判斷主語是復(fù)數(shù)形式,fish supplies“魚類供給”,故填supplies。

4考查名詞。句意:但這種情況可能會(huì)改變,因?yàn)樗鼈兊聂~類供應(yīng)進(jìn)一步進(jìn)入南大洋,那里只有少數(shù)幾個(gè)島嶼可以為鳥類提供棲息地。此處考查固定表達(dá)a handful of“少數(shù)”,handful“一把(的量)”,故填handful。

5考查定語從句。分析句子可知,此處是定語從句關(guān)系詞,先行詞islands在從句中充當(dāng)主語,應(yīng)用關(guān)系代詞,故填that/ which

6考查冠詞。句意:如果它們尋找魚類時(shí),一個(gè)往返不得不游上超過435英里,它們等待食物的幼鳥就會(huì)餓死,因?yàn)樗鼈兊闹緝?chǔ)存會(huì)變得越來越少。trip是可數(shù)名詞,結(jié)合上下文可知,此處意為“一次往返(的旅行)”,是泛指,應(yīng)用不定冠詞,且round是輔音音素開頭,故填a。

7考查形容詞。分析句子可知,此處應(yīng)用形容詞作為表語,再結(jié)合句意可知,此處意為“越來越少”,應(yīng)用比較級(jí),故填fewer

8考查固定句型。此處考查固定句型it take sb some time to do sth.“做某事花費(fèi)某人多少時(shí)間”,其中it是形式主語,不定式是真正的主語,故填to deliver

9考查時(shí)態(tài)和語態(tài)。分析句子可知,此處是定語從句的謂語動(dòng)詞,主語studypublish之間是被動(dòng)關(guān)系,再由so far判斷為現(xiàn)在完成時(shí),故應(yīng)用現(xiàn)在完成時(shí)的被動(dòng)語態(tài),主語study是第三人稱單數(shù),故填has been published

10考查介詞。句意:法國(guó)斯特拉斯堡大學(xué)的科學(xué)家們的研究已經(jīng)發(fā)表在《自然氣候變化》雜志上,他們警告說,魚類向南遷徙的影響可能會(huì)導(dǎo)致企鵝的大量減少。此處考查固定短語give rise to“引起,導(dǎo)致”,故填to。

【題目】As I write this, I’m sitting on a bus back to Santiago in Chile where I am working 1 a writer. I’ve just spent the weekend in a city called La Serena north of Santiago. I was lucky enough to see the flowering desert, a natural scene that 2 (occur) around every five years here in the Atacama Desert.

3 (follow) a particularly large amount of rainfall earlier, a(n) 4(vary) of flowers come into blossom. Bright purple flowers create 5 unbelievably beautiful scene at the base of the surrounding mountains.

6 (have) a look at this wonderful treasure of nature, we took a bus from La Serena to a nearby town and then rented a car to go to the desert. 7 we saw did not disappoint us, and as expected it was even more fascinating than the pictures we had seen online. The bloom was particularly 8 (impress) this year due to the strong presence of El Nio (a band of warm water in the Pacific Ocean that changes the temperatures and increases the rainfall in certain areas). The vast carpet of color 9 spread into the distance towards the green hills was 10(simple) breathtaking and deserved a large amount of photos! A real reminder of the beauty our planet can provide.
