答案:C
6.解析:词义猜测题。根据第二段第一句“Now,researchers at MIT have developed...underwater communication”可知,麻省理工学院的研究人员发明了一种可能改变水下通信的方法,使从水下与地面上的人进行沟通成为可能,故画线词与A项“可实现的”意思最相近,故选A。
答案:A
7.解析:推理判断题。 文章第三段详细讲述了TARF系统的工作原理:该系统使用一个水下机器向水面发送声呐信号,使震动与数据的1和0对应,然后水面接收器读取并对这些微小的震动进行重新编码,这样可以在水下与地面上的人进行通信。因此D项正确。
答案:D
8.解析:标题判断题。通读全文可知,本文主要介绍了科学家发明的一种解决了在水下与地面上的人无法进行通信联系这个难题的系统,研究人员将会把它投入到真实的状况下进行验证,因此B项最适合做本文标题。
答案:B Ⅱ.书面表达
(2019·潍坊高三模拟)假定你是李华,你的澳大利亚朋友William寒假期间要来中国游玩,行程中计划在你家住三天,请你给他写一封邮件,内容包括:
1.住宿条件; 2.活动安排;
3.其他事项(气候差异、着装提醒等)。 注意:1.词数100左右;
2.可以适当增加细节,以使行文连贯。
【写作思路】 本篇书面表达是一篇提纲类应用文,即邮件。话题贴近考生生活,实用性很强,充分体现了语言的生活化和应用化的特点。文章要包含三个部分的内容:介绍住宿条件;活动具体安排;注意事项简要介绍。在具体的行文中,可适当加入一些合理的过渡情节,以使行文连贯、自然;在语言上,要简洁、明了;最后,恰当运用一些高级句型为文章增色。
