71. hang 意作“懸掛”時,時態(tài)變化“hang,hung,hung”;意作“吊死,該死”時,時態(tài)變化為“hang ,hanged ,hanged”。此處作“懸掛”講,且全篇敘述都用的是過去時,所以應(yīng)該使用過去式hung。 72. “warn sb of sth ”為固定搭配,所以將from改成of。 73. 定語從句中,如先行詞后出現(xiàn)逗號,為非限制性定語從句,則關(guān)系代詞應(yīng)用which。 74. “tired”不是動詞,是分詞形式的形容詞。一個句子中不可能沒有謂語動詞,所以填上一個“were”,因為“be tired”表示“勞累”。 75. “B.ut today ”暗示這句話應(yīng)轉(zhuǎn)為現(xiàn)在時,所以應(yīng)把過去式sent改成現(xiàn)在時send。 76. “modern lighthouse”辯認(rèn)identify 的對象是它自己,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. 動詞變成形容詞修飾名詞時,如果與名詞是主謂關(guān)系,動詞變成-ing形式,如果與名詞是動賓關(guān)系,動詞變成過去分詞形式!發(fā)ight”與“revolve”應(yīng)是主謂關(guān)系,所以應(yīng)用動名詞形式revolving來修飾名詞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,因為 其后緊跟著一個名詞“the signal”。 80.a(chǎn)nd 前后句子結(jié)構(gòu)對稱,“which lighthouse it is ”與“where it isolated”對稱,不需要being。另外,此處強調(diào)的是狀態(tài),不是動作,“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.
