答案解析

解析1. unusual解析:分析本句句法得知,本句真正的主语是 not to use one,在本句中one指的是a cell phone,因此真正的主语是 not to use a cell phone此空白处放在谓语 be considered后面作表语成分。结合句首“ Millions of people are using cellphones today”可得知使用手机是非常普通的事情。因此,应将提示词形容词 usual加上否定前缀un-改成 unusual放入句中,构成“it is actually considered unusual not to use one.”(不使用手机实际上是不寻常的事),双重否定即为肯定,意同“使用手机是非常普通的事”。2. communication解析:本句空白处放在介词of的后面,空白处用来修饰名词 means(手段,方法)。因此,将提示词动词 communicate改成名词 communication放在句中,即手机不仅仅只是交流的工具而已.3. connected解析:本句空白处放在and后面表示填入的词需和and前面的cool保持词性一致。因此将提示词动词 connect加上ed改成形容词connected(有联络的;连在一起的),符合语境。4. explosions解析:本句空白处放在定冠词the后显然需要填名词,分析本句句法得知谓语是make因此将提示词动词 explode改成名词 explosion再改成其复数形式 explosions,符合语法和语境。5. concerned解析:本句空白处放在be动词are后面显然需要提示词动词 concern作出相应改变。因此,将提示词动词 concern改成形容词 concerned放在句中,意为“对某事担心”。6. publicity解析:本句空白处放在形容词 negative的后面以及介词of的前面,提示需填入名词,因此将提示词形容词 public改成名词publicity (宣传)符合语境。7. proof解析:proof后显然需要填入名词,因此将提示词动词四改成符合语境的名词prof(证明正据)即可。8. detected解析:分析本句句法结构得知,本句为被动语态且空白处要求考生把被动语态补充完整。因此,将提示词动词 detect改成过去分词detected即可。9. potentially解析:本句句法结构完整,另外提示词放在形容词 harmful前面,可以得知是用来修饰该形容词的。因此,将提示词形容词 potential加上后缀-ly改成副词 potentially即可10. warning解析:本句空白处放在不定冠词a之后以及名词 label前,提示需填入形容词来修饰label,因此,将提示词动词warm改成现在分词warning(警告性的)即可。
