问题 Just consider that we use hardly one hundred-thousandth of the heat______in coal and that could be extracted from it.
选项 A、it is
B、there is
C、as is
D、what is
答案 B
解析 there is in coal是定语从句，省略了关系代词that，复原后应为：…we use hardlyone hundred—thousandth of the lleat that there is in coal。当定语从句是there be句型时，关系代词that经常省去不用。题句如果选it is，那么与主句之间没有连接词；如果选what is，what不需要先行词，而句中已给heat；as虽然是关系代词，但所引导的句子在语义上有"像……一样"的含义，不符合该句的意思，所以这几项均错。
