    C.Where there are skyscrapers, television reception is poor
    D.The two World Trade Center towers are skyscrapers

    答案:B
    解析:
    是非判断题。B项的内容与文章不符,本文虽未直接提到摩天大楼是什么时候出现的,但间接否认摩天大楼是在20世纪90年代末期首先出现的:“…and new steel-and—glass skyscrapers were widelycriticized.”这一个“新”字是说这种钢材玻璃型摩天大楼是在20世纪60年代末期出现了,而不是说摩天大楼是在这一时期出现的。

    B

    Europeans figured out ways to use coffee during the 1670s.

    C

    During the l770s, more and more Americans began to drink coffee.

    D

    Coffee is a refreshing drink.


    正确答案: C
    解析:
    细节判断题。根据文中第四段第一行提到“It is often said that after the Boston Tea Party of l773”可知,“波士顿倾茶事件”在1773年发生,A选项正确。接着文章又说道“Americans everywhere switched over to drinking coffee.”即,1773年“波士顿倾茶事件”之后,人们开始从喝茶转向喝咖啡,也就是越来越多的人选择喝咖啡,C选项正确。由文章第一行“Coffee is a powerful drink.… it helps keep US awake and active”可知,咖啡能使人保持清醒和活跃,即咖啡是“提神(refreshing)的饮料”,D选项正确。根据文章中第二段内容可得:14世纪时,有人发现了咖啡使用方法,15世纪传遍阿拉伯世界,之后又过了150年,即17世纪60年代,它才席卷了欧洲,其中并没有直接提到是欧洲人发明出了使用咖啡的方法,而且时间也不是在17世纪80年代,因此B项描述不符,故答案选B。

  • 第10题:

    单选题
    According to the speaker, how does the price of an electronic keyboard compare with the price of a piano?
    A

    The electronic instrument is much more expensive.

    B

    The electronic instrument is slightly more expensive.

    C

    The piano is slightly more expensive.

    D

    The piano is much more expensive.


    正确答案: D
    解析:
    事实细节的找寻和判断。题干中的关键词为price,从而定位到录音中的“One of the most important reasons for the great popularity of electronic instruments is, of course, their relatively low price.”,可知电子乐器之所以如此盛行,其中一个主要原因就是其价位相对低廉。由此可推测,与电子钢琴相比,传统钢琴要贵得多。因此选项D为正确答案。
    【录音原文】
      We are rapidly nearing the end of this course in history of classical music. We have covered several centuries in a very short time. Much too short to do the music justice, of course, but then this is a survey course. From now until the end of this term, we will be talking about and listening to electronic music. You probably already know that it was in the 1950s that musical computers and synthesizers first appeared in universities. The first commercial synthesizers were sold about this time, too. The sophistication and complexity of these instruments has now increased to the point that they can produce almost any kind of sound. Some alarmists believe these new instruments will bring an end to classical music or that they already have. You know I don’t share this view, though I agree we are in the midst of revolution in instrument design. This, however, is not the first such revolution in musical history and probably not the last one either. Remember we’ve already studied the similar case in the early 19th century when the piano replaced the harpsichord and modem brass and wind instruments came into being. One of the most important reasons for the great popularity of electronic instruments is, of course, their relatively low price. Well, just look at it, only about 400 dollars for a piano. Naturally this has done a lot to increase sales for electronic instruments, expecting them to completely replace acoustic instruments.

    正确答案: A
    解析:
    主旨题。文章前半部分主要谈及当前大学生在实利主义驱使下选择的专业大都与当前能挣钱的专业有关这一社会现实;文章后半部分阐述学习知识重在学习什么,解决什么问题。作者认为,人类文明知识浩瀚,但重要的是要学会怎样思考,学习看清事物之间的联系,不仅要学习专业知识,而且要扩大教育视野,培养人的道德品质,尤其注重从长远的而不是从短期的利益上来看问题。这与D项正吻合。

    Which of the following is true about the Internet according to the passage?
    A

    Americans were more in contact before the advent of the Internet.

    B

    The Internet is weakening the tie of social networks.

    C

    If you use the internet, you are more likely to get help from network members.

    D

    Internet users are more likely to receive help from non-users.


    正确答案: B
    解析:
    录音中最后一句提到“Internet users are more likely than non-users to receive help from network members.”(网络用户比非网络用户更有可能获得来自网络成员的帮助),由此可知如果你使用网络,你更有可能得到网络成员的帮助,所以选C。
    【录音原文】
      As the size of a person’s social network increases, it becomes more difficult for people to contact a large percentage of network members. The percentage of one’s social network contacted declines as network size grows. This pattern holds true for almost all forms of contact analyzed in the Social Ties survey. The one exception is email.
      As the size of people’s social network increases, the percentage of one’s social network contacted weekly by email does not decline, but remains about the same at about 20% of their ties. Several qualities of email help explain this finding. Email enables people to maintain more relationships easily because it is convenient as a communication tool and it gives the control in managing communication. The nature of email is such that people could carry on conversations at different times and at their leisure. This makes it possible for a quick note to an associate, whether it is about important news or seeking advice on an important decision. Moreover, it is almost as easy to email a message to many people as it is to email to only one...
      Contrary to fears that email would reduce other forms of contact, there is “media multiplexity”: that is, the more contact by email, the more in-person and phone contact. Therefore, Americans are probably more in contact with members of their communities and social networks than before the advent of the Internet. And Internet users are more likely than non-users to receive help from network members.
