解析:1.A. 解析:根据all的习惯搭配结构:all + 指示代词, 因此首先排除B。 结合前句内容,空格处的代词应该指代前句中提到的敏锐的眼睛和耳朵, 反应迅速的大脑, 手和大脑之间的协调, 因此应该选择指代复数的指示代词these.
2.D. 解析:与side 搭配的介词是on.
3.B. 解析:空格所在的句子说它们观察智能车左右两侧的..., B放入空格中最恰当。
补充: to:在
e.g. The village lies to在 the east of the woods.
4.C. 借助空格所在局部搭配结构高度...,直接判断高度自动化的搭配通顺,因此C 是答案。
5.B. 解析:B和C都是彼此, 相互,互为近义词, 所以相互排除掉; 空格后出现的是复数名词, 因此B是答案。
6.A/D.解析:空格所在的局部机构说根据这个信息, 它为智能车选择合适的..., 因此判断A 和D合适。
7.C.解析:根据空格所在的局部结构判断C是答案。
8.A. 解析:空格所在的句子说他...反应,结合前句内容及常识判断A最可能成为答案。
9.C. 解析:空格所在的句子说小型照相机连续地把图像...到大脑, 因此C放在空格中合适。
10.B. 解析:空格所在的句子说它在100毫秒的时间里...图像的处理, 根据该句内容判断B是答案。
11. A。 解析:B和D是近义短语结构, 因此相互排除掉。 空格所在的句子说然而, 世界上最好的司机做出反应...需要1秒钟, 因此判断A是答案。 第10题和第11题所在的句子把虚拟司机和人类最好的司机进行反应速度的对比,显然这是利用具体事实的分析以论证该段开头部分的观点句, 因此进一步肯定第8题的答案是quickly。
12.C. 解析:因为前一句已经是however引导的表示转折关系的句子, 因此不可能接着又出现however引导的另一转折句,所以首先排除B。 空格位于句首,而且有一个逗号与句子其他部分隔开, 因此空格处应该出现逻辑副词。 A 和D在用作逻辑副词的用法和词义上接近, 因此相互排除, 因此答案为C。 从空格所在句子的句意上看, 该句引出另一信息, 因此从句意上判断也需要besides 引出表示递进关系的句子。
13.D. 解析:直接借助空格所在的局部搭配结构判断发生率)是答案。
14.A. 解析:空格所在的句子说专家...我们现在还不能这么做, 因此判断A是答案。
15.D. 解析:空格所在的句子说他识别不同东西的能力仍然还..., 空格后句说他现在只能驾驶智能车在高速路上行使。 既然能在高速路上行使,则其应该具备一定识别物体的能力, 而且应该已经经过检测, 因此排除A和C未经试验的); few应该修饰可数名词的复数形式, 而句子主语是单数, 因此排除B, 答案是D。
