16、发生呢？1解析：由空格后的do things you have no control over可知，手机病毒会迫使人们做他们无法控制的事情。但get和force要用带to的不定式作宾补，而damage的含义与上下文不吻合，故此处用make sb. do sth.结构。答案：C2解析：用及物动词say表示电脑专家这样“说”，前面的直接引语是它的宾语。答案：D3解析：由后文的it would cause .emergency number可以看出，手机感染病毒后乱打电话。call表示“拨打电话”。答案：D4解析：由前文的eat into, operating software等词表明病毒是在手机处

17、于工作状态时攻入，继而关闭你的手机，消除其中的内容。答案：A5解析：使用手机时遇到上述情况会引起诸多不便，这自然让人觉得生气(angry)。答案：B6解析：此处message和information均符合语境，但根据空格后的them可知此处指代的是可数名词，故确定为messages。答案：A7解析：由前文“病毒会到处散发你手机上的信息”可推知此处指“还会记下你的密码(password)”。答案：B8解析：该段讲述的是手机的功能，如能上网、发邮件等，自然此处指“还能下载(download)软件”。答案：C9解析：正是由于手机有上述功能，才能成为黑客的攻击目标。target“目标”。答案：D10解

18、析：it指上文所讲的事，手机受电脑病毒攻击这件事从技术角度讲是可能的(possible)。答案：B11解析：既然是antivirus(抗病毒)，当然是“杀毒软件”。hardware“硬件”；software“软件”。答案：B12解析：如果手机上了网，就会和电脑一样传播病毒或威胁。答案：C13解析：如果手机上了网，就会成为攻击目标。这里和上文第9空形成呼应。答案：D14解析：表示“在手机上的信息”用介词on。答案：C15解析：此处和前文第3空所在句子一样，指手机受到病毒袭击后就会不断地打向白宫、警察等。dialcall，意为“拨电话”。答案：B16解析：在这种情况下急救中心的接线员就只好关闭系统

19、以免受到干扰。答案：C17解析：急救电话被停止，直到这令人讨厌的病毒被清除掉(remove)。答案：A18解析：SMS是short message service的缩写，故本题用or表示“或者说，换句话说”。答案：C19解析：由后文的by sticking to their traditional phones可知，手机用户也可以通过使用传统的移动电话躲开(avoid)病毒。答案：B20解析：可以上网的手机有被病毒入侵的危险，人们可以使用不带网络连接的传统电话，不与网络连接。答案：D.七选五阅读Online Friends and LoveIn so many ways, cyberspace

20、 mirrors the real world. _1_ Others buy and sell products. Still others look for friendship, or even love.

24、 of this may be fine if the relationship stays in cyberspace. _5_ With so many unknowns, its easy to let ones imagination “fill in the blanks”. This leads to disappointment when couples meet in person. So, before looking for love in cyberspace, remember the advice of Internet pioneer Clifford Stoll：

25、“Life in the real world is far richer than anything youll find on a computer screen.”A. When we talk with others on line, we can express ourselves freely.B. But some Internet users want more than just someone to chat with.C. People ask for information, play games, and share hobby tips.D. Generally speaking, online friends and love are worth seeking for.E. Because the Internet gives users a lot of control over how others view them.F. Rather, a persons thoughts or at least the thoughts they type are what really count.G. But not knowing a person is a big problem in a love relationship.答案：15CFBEG
