71. hang 意作“懸掛”時(shí),時(shí)態(tài)變化“hang,hung,hung”;意作“吊死,該死”時(shí),時(shí)態(tài)變化為“hang ,hanged ,hanged”。此處作“懸掛”講,且全篇敘述都用的是過(guò)去時(shí),所以應(yīng)該使用過(guò)去式hung。 72. “warn sb of sth ”為固定搭配,所以將from改成of。 73. 定語(yǔ)從句中,如先行詞后出現(xiàn)逗號(hào),為非限制性定語(yǔ)從句,則關(guān)系代詞應(yīng)用which。 74. “tired”不是動(dòng)詞,是分詞形式的形容詞。一個(gè)句子中不可能沒(méi)有謂語(yǔ)動(dòng)詞,所以填上一個(gè)“were”,因?yàn)椤癰e tired”表示“勞累”。 75. “B.ut today ”暗示這句話應(yīng)轉(zhuǎn)為現(xiàn)在時(shí),所以應(yīng)把過(guò)去式sent改成現(xiàn)在時(shí)send。 76. “modern lighthouse”辯認(rèn)identify 的對(duì)象是它自己,所以應(yīng)該使用反身代詞itself。 77. 此句意思是“l(fā)ight”像“giant firefly ”,as不表示“像”的意思,所以將其改成like。 78. 動(dòng)詞變成形容詞修飾名詞時(shí),如果與名詞是主謂關(guān)系,動(dòng)詞變成-ing形式,如果與名詞是動(dòng)賓關(guān)系,動(dòng)詞變成過(guò)去分詞形式!發(fā)ight”與“revolve”應(yīng)是主謂關(guān)系,所以應(yīng)用動(dòng)名詞形式revolving來(lái)修飾名詞light。 79. How 與however后面直接接形容詞,然后再加名詞,如:How beautiful the flowers are !what 與whatever后面直接接名詞,如:What beautiful flowers!此句應(yīng)用whatever,因?yàn)?其后緊跟著一個(gè)名詞“the signal”。 80.a(chǎn)nd 前后句子結(jié)構(gòu)對(duì)稱,“which lighthouse it is ”與“where it isolated”對(duì)稱,不需要being。另外,此處強(qiáng)調(diào)的是狀態(tài),不是動(dòng)作,“being”表示正在定位于何處。
Model Composition
As can be clearly seen from the cartoon, a bird is sitting on the top of a huge ax, with tears streaming from its eyes. Because all the trees are cut down, the bird will have no habitat. The cartoon conveys the meaning that it is urgent to preserve the woods for the birds and protect the environment for human beings.
The cutting of trees, as well as the destruction of our environment, may lead to several harms as follows. In the first place, the trees provide us with many vital things we humans need, such as oxygen, food, shelter and so on. The animals, such as the bird in the picture, also need the trees. In the second place, if trees are cut down, then there will be nothing to retain the rain water, thus floods will happen more often in the future. Last but not least, there is only one earth. If the environment is destroyed, then we will have no place to live in.
Since this phenomenon causes so many harmful effects, we have to come up with some measures to deal with it. First of all, the authorities should adopt the policy of “sustainable development”, just as our government has been doing. What’s more, every citizen should realize the seriousness of the problem and make concerted efforts to protect our environment.
