ACBAB BCCAB解析【主旨大意】眼睛是心灵的窗户。我们应该怎样来保护眼睛呢？本文介绍了科学用眼的方法。1.考查名词的用法。每个人都知道眼睛的“重要性”；2.考查连词的用法。前句和后句意义发生转折，所以用but；3.考查动词不定式的用法。“如何”保护你的视力；4. 考查keep的用法。句意理解：你不应该使你的眼睛长时间“工作”；5.考查连词的用法。一小时“或”两小时；6.考查名词的用法和固定搭配。have a rest 固定词组；7.考查名词的意义。in the sun 在阳光下；8. 考查代词的用法。前文中的主语一直是you，所以承接下来也应用you;9.考查名词的用法。in a word 一句话；10.考查形容词的用法。保持“好”的视力，用good。
