18、on4.caution5.criteria6.distinguish7.product8seized9.file10.merciful.1.A此题可根据句意判断，便于人们携带东西应选carry。bring“带来”；find“发现”；put“放”，均不合句意。2D此题是典型的as.as.结构。根据句意“没有哪些发明能像轮子的发明有那么大的效用”可知答案为D项。3C世界开始发生变化了，而不是出现(appear)、介意(mind)或上升(rise)。4A因为世界上已几乎没有未知的地方，所以人们不必再探索了，强调没必要而不是不想、不喜欢或决定不。5Cmake life better为习惯性搭配，意思是
19、“使生活更加美好”。6B根据句意，这一切已经成为我们今天生活的一部分，所以选part。7D根据上下文可知，此处主要讲更多的发明创造，故选D项。8Acome out“出现”；come in“进来”；come away“脱落，脱开”；come about“发生，转向”。此处为“出现”，故选A项。9C此处的意思是改变人们的衣服种类。pattern形态，样式。10B此题可从下文内容进行选择。下文讲人的健康、寿命，显然只有diseases与此有关。11B根据句意，大多数人期望能活到至少60岁。expect可经常和can(could)搭配使用，并且expect含有“指望”的意思，比hope更易实现。12D
20、根据but可知，前后句意相反。the world我们已经知道、了解，而stars我们还不了解，所以选known。13A句意：人类开始寻找进入太空的方法。故答案为A项。14A此处指“包括在内”应选including。but，except表示“除了以外”；included位置不对，所以不选。15C句意：虽然这只是一个开始。后文的New inventions.也给出了暗示。.1.A细节理解题。由文章第一段第二句可知，光能让银盐变暗这一发现是照相术的基础。2D细节理解题。由第一段倒数第二句可知这张照片的制作方法。3C细节理解题。作者在第二段第二句说照相术的正式开始时间为1839年。4B细节理解题。由第
