[填空题]It is hardly surprising that something called dark energy is hard to study. It is important, though. If it exists at all, it makes up about three-quarters of the stuff in the universe. And if it does not exist, then existing theories of physics will have to be useless.
The latest evidence that dark energy really does exist was produced on December 16th by Alexey Vikhlinin, of the Smithsonian Observatory in Cambridge, Massachusetts, and his colleagues. They used an orbiting X-ray telescope called Chandra to study the way that groups of galaxies grow. They discovered that this growth is restrained in exactly the way that dark-energy theory predicts.
The idea of dark energy was dreamed up ten years ago, to explain why the expansion of the universe that began with the Big Bang seems to be accelerating, rather than slowing down. That unexpected finding was the result of studies of supernovas (超新星) whose apparent brightness (and therefore distance) did not match the previous th

[单项选择]
All of us communicate with one another verbally (口头的) as well as non-verbally. Most of the time we are not aware that we’re doing it. We wave a hand, meet someone else’s eyes or look away, shift positions in a chair. We make these movements unconsciously. But researchers have discovered that there is a system to them almost as consistent (一致的) and comprehensible as language.
Every culture has its body language. The way an Englishman crosses his legs is nothing like the way a male American does it. In talking, Americans are likely to end a statement with a lowering of the eyelids. They conclude a question with a lift of the hand or a widening of the eyes. With a future-tense verb they often gesture with a forward movement. There are regional idioms too. Your sex, ethnic background, social class and personal style all influence your body language. Nevertheless, you move and gesture within a certain idiom.
Usually, the wordless communica
