这道题太奇怪了，32.According to the passage, bydrogen can become a metallic-like liquid when it isA)extremely hot, B)combined with helium, C)similar atmospheres, D)metallic cores, 我在读文章的时候觉得应该是under great pressure 这样的答案（根据文章中Normally，hydrogen is a gas, but under pressure of millions of kilograms per square centimeter, which exist in the deep interior of a metal.) 很多地方答案给的是C，还有给D的，但我实在是看不出来啊，it is 跟CD两个选项也对不上啊，ＣＤ后面的名词还都是复数的呢，求高手指点迷津！谢谢啦！

此题系印刷错误，与33题备选项出现了串行。正确的备选项为：（C）similar to atomospheres（D）under great pessuesthe Key is D
