Question

【題目】閱讀下面材料，在空白處填入1個適當(dāng)?shù)膯卧~或括號內(nèi)單詞的正確形式。

Wild elephants that destroy crops and damage trees 【1】(be) a serious problem in many parts of Africa. But there could be a simple and 【2】(relative) safe way to stop them in their tracks, by 【3】(employ) the talents of the tiny African honeybees.

The number of elephants in Kenya 【4】(rise) over the past ten years, with some disastrous results. Not only do these huge animals attack local farms 【5】 they step someone to death an average of once every two weeks. Now a biologist has discovered a possible threat: the elephants are extremely aware 【6】 trees that house honeybee hives.

'I am 【7】(puzzle) why nobody has thought of this before, 'says Fritz Vollrath at the University of Oxford. 'When an elephant knocks a beehive he runs and the bees will follow him for miles. ' He says that placing hives of the honeybees around local farms could be 【8】 effective way to threaten the animals. Vollrath put 30 unoccupied and 6 occupied 【9】(beehive) in some of the trees growing on a bush frequently damaged by elephants. On average the elephants attacked 9 out of 10 trees that didn’t have hives. But 【10】(them) avoided all six trees with occupied hives. The elephants also left along one–third of the trees with empty hives, suggesting that some had learnt not to take the risk.

【解析】

這是一篇記敘文。非洲的野象經(jīng)常出來損害莊稼、樹木，甚至造成平均每兩星期有一次傷人至死事件，后來人們發(fā)現(xiàn)一個奇妙的解決這事的辦法，他們利用蜜蜂來制裁這些野象，效果很好。

【1】考查時態(tài)。此處是句子謂語動詞，本文講述一般事實，故用一般現(xiàn)在時，主語elephants是復(fù)數(shù)，謂語動詞應(yīng)用復(fù)數(shù)形式，故填are。

【2】考查副詞。此處應(yīng)用副詞修飾形容詞safe，故填relatively。

【3】考查動名詞。此處應(yīng)填employ的動名詞形式作為by的賓語，故填employing。

【4】考查時態(tài)。此處是句子謂語動詞，由over the past ten years判斷為現(xiàn)在完成時，主語the number of elephants作主語是第三人稱單數(shù)，故填has risen。

【5】考查連詞。此處考查短語not only…but (also)…“不但…….而且……”，故填but。

【6】考查介詞。此處考查短語be aware of “清楚/了解”，故填of。

【7】考查形容詞。此處應(yīng)用形容詞作表語，又意為“感到困惑的”，故填puzzled。

【8】考查冠詞。結(jié)合上下可知，此處意為“一個有效的方式”，是泛指，應(yīng)用不定冠詞，又effective是元音音素開頭，故填an。

【9】考查名詞的數(shù)。根據(jù)前文的30和6判斷此處用復(fù)數(shù)形式，故填beehives。

【10】考查代詞。此處是句子主語，應(yīng)用them的主格形式，故填they。

第4小題考查現(xiàn)在完成時

現(xiàn)在完成時表過去的動作對現(xiàn)在造成的影響，其結(jié)構(gòu)為have/has done，常見的標(biāo)志有：already, yet, since, for, up to/till now, so far, in/during/over the past/last + 段時間。以本題為例：

此處是句子謂語動詞，由over the past ten years(在過去10年里)判斷為現(xiàn)在完成時，主語the number of elephants作主語是第三人稱單數(shù)，故填has risen。
