根据这一句的意思,我们发现选项Doften need to dig holes near some subsurface structures与原文的意思相符。这是因为,我们可以从原句中找到 need, excavate, in the vicinity of , subsurface structures。这几个词事实上就是这个句子的主干部分,并且这也与备选句的意思相同,因此应该选D。而选项A虽然也合乎情理,但在文中没有出现,所以只是干扰项,不能选作答案。
Q2.Trial pits...
同样,我们发现原句是:One way to verify the location of such buried objects is to cautiously dig a trial pit to expose the object in question.
读完Trial pits所在的这个句子,我们发现选项B与F都与原句的意思相近。那到底应该选哪一个呢?通过分析可以发现,dig trial pits 的目的并不是 expose the object,而是 verify the location of the buried objects。因此,F才是正确的选项。
Q3. Mechanical digging equipment...
原句:Where mechanical digging equipment is used, an undocumented or misaligned utility line can be easily be damaged if it is not observed by the excavation workers. Gas and electricity lines present very obvious safety threats in this situation.
从Mechanical digging equipment所在的句子我们可以看到这样几个词:undocumented, utility line, easily be damaged.。把这几个词连成句子后恰好和备选项Cdamages easily undocumented utility lines意思一样。但能否就贸然选C呢?仔细阅读原句可以发现,damage easily the undocumented utility line 是在没有被 excavation workers 发现的情况下,因此可以说是受这一条件限定。如果选C,就以偏概全,把特定情况下发生的问题说成了总的经常性的问题。自然,C不能选择。
