We shouldnt w_ electricity.答案：waste.解題思路：此題考查waste的用法，句意為“這里足夠明亮了，請(qǐng)把燈關(guān)了。我們不應(yīng)該浪費(fèi)電?！惫侍顚憌aste，這里waste作動(dòng)詞。2. environment【用法】n. 環(huán)境它是由動(dòng)詞environ（包圍）名詞后綴-ment 構(gòu)成的名詞。類似的詞有：development， excitement【例句】The children have a happy environment at school.【考查點(diǎn)】詞義理解。【易錯(cuò)點(diǎn)】environment的拼寫?！究碱}鏈接】We should prevent the pollution of the e_.答案：environment。解題思路：此題考查environment的拼寫，句意為“我們應(yīng)該防止環(huán)境污染?！惫侍顚慹nvironment。3. product【用法】n. 產(chǎn)品，制品【例句】The company sells plastic products. 與product相關(guān)的動(dòng)詞是produce，意思是“制造，生產(chǎn)”。如：Many kinds of machines are produced in this factory. 【考查點(diǎn)】詞義理解?！疽族e(cuò)點(diǎn)】product的拼寫?！究碱}鏈接】We have to find the right p_ for the market.答案：product。解題思路：此題考查product的拼寫，句意為“我們要找出適合市場(chǎng)需要的產(chǎn)品?！惫侍顚憄roduct。即學(xué)即練 Its w_ to keep the light on in the bright room. Those factories are causing a lot of e_ pollution. Our factory produces a kind of new p_. They are very popular to people. Dont w_ money on junk food. （二）重點(diǎn)短語(yǔ) 短語(yǔ)學(xué)習(xí)1. throw away【用法】“扔掉，拋棄（某物）”【例句】You should throw away these chairs and buy new ones.【考查點(diǎn)】短語(yǔ)本意。 【易錯(cuò)點(diǎn)】throw 的過(guò)去式和過(guò)去分詞形式?！究碱}鏈接】他問我你剛才扔掉了什么。He asked me what you _ just now.答案：threw away 解題思路：此題考查throw away的時(shí)態(tài)，句中“你剛才扔掉了什么”是一個(gè)賓語(yǔ)從句，要用陳述句的語(yǔ)序，由表示時(shí)間的just now可知要用一般過(guò)去時(shí)，故填寫threw away。2. instead of【用法】“代替，而不是”（后接名詞，代詞和v-ing形式）【例句】What about eating fish instead of meat today? 今天不吃肉改吃魚怎么樣？You should go out instead of staying at home. 你應(yīng)該出去而不是呆在家里。注意：instead adv. “代替，反而”，單獨(dú)用時(shí)放在句末。【例句】Why not play football instead? If you cant go, let him go instead. 【考查點(diǎn)】instead of的用法。【易錯(cuò)點(diǎn)】instead of 與rather than易混淆。辨析：instead of 和rather than的區(qū)別：都有“而不是”的意思instead of：“代替，而不是”，重點(diǎn)詞是of，它是介詞，所以后接名詞，代詞和v-ing形式，尤其需注意的是動(dòng)詞該用動(dòng)名詞形式，即v-ing；rather than：“（是）而不是”，它是連詞，前后成分在形式上必須保持一致，所以后面的結(jié)構(gòu)應(yīng)該與前面一樣，就有可能出現(xiàn)代詞主格，動(dòng)詞的各種形式等，不一而足，但關(guān)鍵是要和與它對(duì)比的結(jié)構(gòu)形式一致！【例句】Ill go there instead of him.I rather than he（與I一致）will go there.Yesterday he walked here instead of driving here.Yesterday he walked here rather than drove（與walked一致）here.【考題鏈接】有些廢品是可循環(huán)再利用的，所以我們最好是賣掉它而不是扔掉。Some waste is reusable, so wed better sell it for recycling _.答案：instead of throwing it away/ rather than throw it away。解題思路：此題考查“而不是”的翻譯，由于“而不是”可譯為“instead of”或“rather than”，需要注意它們后面動(dòng)詞的形式，instead of后只能跟動(dòng)名詞，故寫為instead of throwing it away；而rather than后的動(dòng)詞要和前面的動(dòng)詞形式保持一致，故寫為rather than throw it away。3. do harm to【用法】對(duì)造成傷害 do harm to sb./ sth. = do sb./ sth. harm “給某人/某物造成傷害，傷害（某人），損害（某物）” do no harm to sb./ sth. 對(duì)某人/某物沒有造成傷害【例句】In my opinion, cheating in exams does great harm to our study.我認(rèn)為考試作弊對(duì)學(xué)習(xí)非常有害。【考查點(diǎn)】短語(yǔ)本意及句型轉(zhuǎn)換。【易錯(cuò)點(diǎn)】句型轉(zhuǎn)換?！究碱}鏈接】Hard work does no harm to anyone.Hard work _ _ _ _.答案：does anyone no harm。解題思路：此題考查do harm to sb.的句型轉(zhuǎn)換，由于do no harm to sb.do sb. no harm, 故寫為does anyone no harm。4. make a difference to 【用法】對(duì)產(chǎn)生重大影響，對(duì)很重要 注意：to是介詞，所以后跟名詞或動(dòng)名詞。當(dāng)中的a可以用“no, some”代替，表示“對(duì)沒什么影響/有些影響”等意思?！纠洹縎uccess or failure in the exam will make a difference to the students. 【考查點(diǎn)】短語(yǔ)本意。【易錯(cuò)點(diǎn)】difference易寫成different?！究碱}鏈接】空氣對(duì)她的身體有很大影響。The air has _ her health. 答案：made a difference to。解題思路：此題考查的是make a difference to的翻譯，在這里要翻譯的是“對(duì)有很大影響”，由于句子前面有一個(gè)has，說(shuō)明動(dòng)詞make要用過(guò)去分詞，故填寫made a difference to。5. such as 【用法】例如 【考查點(diǎn)】for example, such as 與like的辨析。辨析：for example, such as 與like ：三者都有“例如”之意for example：一般只以同類事物或同類人中的“一個(gè)”為例，作插入語(yǔ)，用逗號(hào)隔開，可置于句首，句中或句末。如：For example, air is invisible（看不見的）。such as：用來(lái)例舉同類人或物中的幾個(gè)例子，后跟名詞或動(dòng)名詞, 不用逗號(hào)隔開。如：We learn many subjects, such as English, Chinese and maths.like: 用來(lái)舉例時(shí)，作為介詞，可與such as互換。但such as用于舉例時(shí)可以分開使用，且不與like互換。如：Some animals like/ such as the cat, the dog and the wolf, dont need to hibernate（冬眠）.He has several such reference books as dictionaries and handbooks.他有幾本像字典、手冊(cè)之類的參考書?！疽族e(cuò)點(diǎn)】for example, such as 與like的用法易混淆?！究碱}鏈接】I like playing ball games, _ basketball and football.A. for example B. such as C. likes答案：B。解題思路：此題考查的是for example, such as 與like的辨析，由于for example放在句中時(shí)，前后要用逗號(hào)隔開，而橫線后沒有逗號(hào)，所以排除A；而like用來(lái)舉例時(shí)，是介詞，不能在其后面加-s，因此排除C而選B。6. stopfrom doing sth. 【用法】“阻止做某事”（from可省略）相當(dāng)于prevent(from) doing sth. / keepfrom doing sth.【考查點(diǎn)】短語(yǔ)本意?！疽族e(cuò)點(diǎn)】不明確from后要用動(dòng)名詞?！究碱}鏈接】We should stop the factories _ the air.A. to pollute B. pollute C. from polluting答案：C 。解題思路：此題考查stopfrom doing sth.的用法，句意為“我們必須阻止工廠污染空氣”，故選C。即學(xué)即練1. The dish smells bad and youd better _.A. try it out B. throw away it C. throw it away2. He is too busy, let me go _.A. instead of B. instead C. rather than 3.

Itsadj.to do sth. 【用法】“做某事是怎么樣的”此句型中動(dòng)詞不定式作主語(yǔ)，it作形式主語(yǔ)。 【例句】Its easy to ride a bike.To ride a bike is easy.如要表達(dá)“對(duì)于某人來(lái)說(shuō)做某事怎么樣”，可寫為“Itsadj.for sb.to do sth.”。【例句】Its easy for me to ride a bike. Its important for us to learn English well. 【考查點(diǎn)】對(duì)此句型的運(yùn)用?！疽族e(cuò)點(diǎn)】不理解動(dòng)詞不定式作主語(yǔ)，it作形式主語(yǔ)。【考題鏈接】Its not right _ rubbish in the street. A. to throw awayB. throwing awayC. throw away答案：A。解題思路：此題考查Itsadj.to do sth.這個(gè)句型，句意為“在街上扔垃圾是不對(duì)的”,故選A。2. 語(yǔ)法：前綴，后綴構(gòu)詞法【用法】（一）常見的前綴形式：1. re-表示“再”，如：reuse，recycle2. in/ im- 表示“無(wú)，不”，如：incorrect，impossible3. un-表示“無(wú)，不”，如：unhealthy，uncomfortable4. dis-表示“不，無(wú)”，如：disappear，dislike5. anti-表示“反對(duì)，防止”，如：anti-pollution，anti-war（二）常見的后綴形式：1. able表示“可能，易于，適合于”，構(gòu)成形容詞，如：eatable，comfortable，movable2. ful 表示“充滿的，具有性質(zhì)的”，構(gòu)成形容詞，如：hopeful，useful，careful3. less與ful相反，表示“少的，不足的”， 構(gòu)成形容詞，如；hopeless，useless，careless4. ment，構(gòu)成名詞，如：development，environment【考查點(diǎn)】前綴，后綴構(gòu)詞法。【易錯(cuò)點(diǎn)】不懂得前綴，后綴的意思及用法?！究碱}鏈接】Dont use so much water. Its very _.（waste)（用括號(hào)內(nèi)所給單詞的適當(dāng)形式填空）答案：wasteful。解題思路：此題考查后綴構(gòu)詞法。句意為“不要用這么多水，這樣很浪費(fèi)”，因此，應(yīng)用waste的形容詞形式，故填寫wasteful。即學(xué)即練1. Be _(care)when you cross the road.2. It is _(possible) for me to finish the work today. Its too hard.3. I dont like travelling by bus, because its _(comfortable).4.
