【題目】閱讀下面短文，在空白處填入1個(gè)適當(dāng)?shù)膯卧~或括號(hào)內(nèi)單詞的正確形式。

The production of coffee beans is a huge, profitable business, but, unfortunately, full-sun production is taking over the industry and bringing about a lot of damage. The change 【1】 coffee is grown from shade-grown production to full-sun production endangers the very 【2】 (exist) of certain animals and birds, and even disturbs the world’s ecological balance.

On a local level, the damage 【3】 (cause) by full-sun fields affects the area’s birds and animals. The shade of the forest trees provides a habitat 【4】 birds and other species that depend on the trees’ flowers and fruits. Full-sun coffee growers destroy this forest home. As a result, many species are 【5】 (quick) dying out. On a more global level, the destruction of the rainforest for full-sun coffee fields also threatens human life.

Medical research often makes use of the forests’ plant and animal life, 【6】 the destruction of such species prevents researchers from finding cures for certain diseases. In addition, new coffee-growing techniques are poisoning the local water and 【7】 (poison) the world’s groundwater in the future.

The loss of shade trees is gradually causing 【8】 slight change in the world’s climate, and studies show that loss of oxygen-giving trees also leads to air pollution and global warming.

It is obvious that 【9】 (grow) much full-sun coffee affects many aspects of life, from the local environment to the global ecology. But consumers do have a choice. They can purchase shade-grown coffee whenever possible, although at a higher cost. The future health of the planet and mankind 【10】 (be) surely worth more than an inexpensive cup of coffee.

【答案】

【1】that

【2】existence

【3】caused

【4】for

【5】quickly

【6】but

【7】will poison

【8】a

【9】growing

【10】is

【解析】

本文為一篇說明文。主要講到通過全日照生產(chǎn)的咖啡豆會(huì)對我們生活帶來許多負(fù)面影響。

【1】

考查同位語從句。句意：咖啡從陰涼生長到全日照生產(chǎn)的轉(zhuǎn)變危及到某些動(dòng)物和鳥類的生存，甚至擾亂了世界的生態(tài)平衡。在這句話中change所引導(dǎo)了一個(gè)從句，通過句意我們可以知道，這里從句所講述的內(nèi)容就是轉(zhuǎn)變的內(nèi)容，因此我們可以推斷出這里時(shí)一個(gè)同位語從句，然后這里只起引導(dǎo)作用。故此題填that。

【2】

考查名詞。句意見上一題。通過空格前面的定冠詞the我們可以知道，空格處應(yīng)該要填名詞。exist的名詞為existence，并且是一個(gè)不可數(shù)名詞。故此題填existence。

【3】

考查非謂語動(dòng)詞。句意：在地方層面上，全天陽光照射造成的損害影響了該地區(qū)的鳥類和動(dòng)物。在這句話中已經(jīng)有了謂語動(dòng)詞affects，所以這里為非謂語動(dòng)詞作定語。傷害和引起為被動(dòng)關(guān)系，所以是過去分詞作后置定語。故此題填caused。

【4】

考查介詞。句意：森林樹木的樹蔭為鳥類和其他依賴樹木花果的物種提供了棲息地。在這句話中所表達(dá)的意思是為鳥類提供，那么“為……提供”我們使用provide…for這一結(jié)構(gòu)。故此題填for。

【5】

考查副詞。句意：結(jié)果，許多物種正在快速滅絕。在這里是要對dying out這一個(gè)動(dòng)詞詞組進(jìn)行修飾，所以需要用副詞來修飾。故此題填quickly。

【6】

考查連詞。句意：醫(yī)學(xué)研究經(jīng)常利用森林中的動(dòng)植物生命，但這種物種的毀滅使研究人員無法找到治療某些疾病的方法。通過句意可知，這里作者想要表達(dá)轉(zhuǎn)折關(guān)系，所以需要用連詞but。故此題填but。

【7】

考查時(shí)態(tài)。句意：此外，新的咖啡種植技術(shù)正在毒害當(dāng)?shù)氐乃�，并將在未來毒害全世界的地下水。句中表達(dá)了新的咖啡種植技術(shù)正在毒害當(dāng)?shù)氐恼l，但是全世界的水暫時(shí)還沒有毒害，在未來會(huì)遭到新技術(shù)的毒害，所以這里用一般將來時(shí)。然后技術(shù)和毒害是主動(dòng)關(guān)系。故此題填will poison。

【8】

考查冠詞。句意：樹蔭的消失正逐漸導(dǎo)致世界氣候的輕微變化。在這里的輕微變化作者并沒有具體說明，所以是泛指要用不定冠詞。此外slight是以輔音音素開頭的。故此題填a。

【9】

考查非謂語。句意：很明顯，種植全日照咖啡會(huì)影響生活的方方面面，從當(dāng)?shù)丨h(huán)境到全球生態(tài)。在這句話中是終止許多全日照咖啡作主語，所以將grow變?yōu)閯?dòng)名詞growing作主語。故此題填growing。

【10】

考查時(shí)態(tài)語態(tài)。句意：地球和人類未來的健康肯定比一杯便宜的咖啡更有價(jià)值。地球和人類未來的健康這是一個(gè)經(jīng)常性的狀態(tài)所以要用一般現(xiàn)在時(shí)。主語是future，則謂語需要用單數(shù)。故此題填is。

【題目】 Not long ago, no one understood that infectious diseases were caused by tiny organisms that moved from person to person. Even now, although we know that tiny living microbes cause disease, how they do so is not always obvious. 【1】 They can also be transmitted through our skin through insect or animal bites. The best way to prevent infections is to block pathogens （病菌）from entering the body.

The first line of defense is to keep germs at bay by following good personal health habits. Wash your hands well. You probably wash your hands after using the bathroom, before preparing or eating food, and after gardening or other dirty tasks. 【2】 Wet your hands thoroughly. Lather（泡沫）up with soap or cleanser, and rub it into the palms and backs of your hands and your wrists. Be sure to clean your fingertips, under your nails and between your fingers. Wash under running water. 【3】

Whether you are young or young at heart, getting vaccinated（接種疫苗）is an essential part of staying healthy. 【4】 such as a temporarily sore arm or low fever, they are generally safe and effective. Vaccinations are essential if you are to avoid getting sick. In general, children should receive the recommended childhood vaccinations. Adults should make sure their vaccinations are up to date. When traveling abroad, check with your health care provider about additional immunizations（免疫）.

【5】 Stay clear of wild animals. Many wild animals, including bats, foxes and coyotes, can spread the virus to humans by biting. Keep your pets away from wild animals, too. Dogs, cats or any other type of warm-blooded animal can pick up the virus and pass the virus along to people.

A.Dry your hands and wrists thoroughly.

B.Use animal control to prevent infections.

C.While vaccines may cause some common side effects,

D.Although vaccines can not prevent some rare diseases,

E.Other wild animals can not transmit the virus and other infections.

F.We do know that most microbes enter through openings in the body.

G.You should also wash up after blowing your nose, coughing, or sneezing.

We live in the countryside. Most of which we see is the beauty of nature. One of the exceptions to the beauty is the litter some people throw out their windows as they are driving on the roads. One of the few drawbacks to living in the countryside is that public service, such as litter collection, are little available than they are closer to the city.

A helping habit that my family practise regularly are picking up litter in our surrounding area. We have become so accustomed to do this that my little brother will often say, “There’s some litter. Daddy, stop the car!” and we would often pull over and pick it up. It may seem strange, and we actually enjoy it. We pick up litter in parks, on sidewalks, practically anywhere. Once I even saw a complete stranger picking up litter close to where we live in. He smiled at me and said, “I saw you doing it, and it seemed like the good idea.”
