Answer 1

分析 84．We ought to plant trees every year．
85．They've already climbed up the top of the mountain．
86．I bought a computer last year．
87．Smoking does harm to our health

解答 答案：
84．We ought to plant trees every year．我们应该每年植树．
85．They've already climbed up the top of the mountain．他们已经爬到了山顶．
86．I bought a computer last year．我去年买了一台电脑．
87．Smoking does harm to our health．吸烟对健康有害．
首先根据图片结合提示词和标点符合明确所要组合的四个句子都是陈述句，四个句子的汉语意思分别是：84．我们应该每年植树．85．他们已经爬到了山顶．86．我去年买了一台电脑．87．吸烟对健康有害．； 84题中用情态动词ought to+动词原形；85题中结合句意用现在完成时，构成是：主语+have/has been+动词的过去分词，短语"爬到山顶"是climb to the top of the mountain；86题中，根据last year判断用一般过去时；87题中根据句子表述的是一般性的事实，判断用一般现在时，短语"对…造成危害"是do harm to，故答案为：
84．We ought to plant trees every year．
85．They've already climbed up the top of the mountain．
86．I bought a computer last year．
87．Smoking does harm to our health

点评 做看图连词成句这种类型的题，首先根据图片结合提示词确定句子类型，如：陈述句、疑问句或感叹句等，然后根据所给单词，明确主语、谓语等句子成分，在确定句意的前提下结合语法知识组合句子．
