Answer 1

分析 这位科学家很匆忙．她必须在夜幕降临之前去取些水进行实验，她正在测试流进海洋的河水．她的任务是查明在海滩附近的海水污染的原因．她提起了水，生气地看着里面的垃圾．旧衣服，塑料袋，纸都在脏水里．"难道没有人意识到他们扔到街上的所有东西都被冲进河流吗？它们又正好流入海洋．她大声地说："要多少年才能使它（海水）重新干净呢？"

解答 46．C 考查名词用法．根据关键部分get some water for her…可知形容词性物主代词后应该跟名词；结合后句She was testing the water in the rivers that went into the ocean（ 她正在测试流进海洋的河水）可推知此处应是指取一些水做实验，结合选项故用名词experiment实验．故选C
47．D 考查名词用法．根据关键部分find out the cause of…可知of相当于名词所有格的功能，其后应该跟名词；结合后句She lifted out the water and looked angrily at the rubbish in it．（她提起了水，生气地看着里面的垃圾）可知水被污染了，所以这里应是指查明海水污染的原因，结合选项故用名词pollution"污染"．故选D．
48．E 考查形容词用法．根据Old clothers，…bags and pieces of paper were in the dirty water可知这些东西都是海水里的垃圾，结合bags可知前面缺少一个形容词来修饰是什么样的袋子，因为是垃圾，所以联想到白色污染塑料袋，结合选项应用形容词plastic"塑料的"．故选E
49．A 考查动词用法．根据"Don't people…that…可知that后引导宾语从句，故空处应该为动词； 结合后面everything they throw onto the street gets washed into rivers？联系前面可知此句为反意疑问句，表达肯定的意义；"他们扔到街上的所有东西都被冲刷进河流"是客观事实，所以此处应是反问难道没有意识到这一点吗？结合选项应该用动词realize"意识到"．故选A．
