大学英语： It is not yet known whether robots will one

　　5. It is not yet known whether robots will one day have vision as good as human vision. (p5)

　　翻译：人们不知道是否有一天机器人能具有像人类一样好的视觉。

　　分析：该句的主语是whether引导的主语从句。(有关知识请见课后补充语法。)，it 是形式主语;as good as human vision是后置定语修饰vision;

　　6. Engineers working on other advances are designing and experimenting with new types of metal hands and fingers, giving robots a sense of touch. (p6)

　　翻译：在其他方面努力取得进展的工程人员正在设计和实验新的金属手臂和手指，使机器人具有触觉。

　　分析：请注意该句中几个-ing的区别：working on other advances是非谓语动词中的现在分词;are designing and experimenting是谓语动词的进行时态;giving robots a sense of touch是非谓语动词的现在分词做结果状语。词组：experiment with sth实验。。。
