问题
Because many of the minerals found on the ocean floor are still (i)________ on land, where mining is relatively inexpensive, mining the ocean floor has yet to become a (ii)________ enterprise.
选项
A、scarce...common
B、accessible…marginal
C、unidentified…subsidized
D、conserved...public
E、plentiful…profitable
答案
E
解析
空格(i):
- 方程等号:where引导的定语从句修饰land,前后同义重复。
- 强词和对应:根据题意,在陆地开矿是相对便宜的,因此空格(i)和inexpensive构成同义,体现在陆地开矿“便宜”。 scarce稀少的,accessible可得到的,unidentified无法识别的,conserved被节约的,plentiful丰富的。 B和E两项合适。
空格(ii):
- 方程等号:because表示因果,同义重复。has yet to还没有,取反。
-强词和对应:because的部分说在陆地挖矿相对便宜,所以because后面说在海洋挖矿不便宜,has yet取反,相当于not,所以空格(ii)和inexpensive取同,体现采矿在陆地是便宜的,而海洋是不(has yet to)“便宜的”。common普遍的(错),marginal不重要的(错),subsidized被补助的(错),public公众的(错),profitable有利可图的(对)。答案选E。
