21、es，and share the same tastes in clothes or music.Some have argued that identical twins have mysterious，even psychic，powers.Although many identical twins claim to know what the other is thinking，there is no evidence to suggest that this is because of special powers. 2 Most of us have met up with a br

27、case，for example，a young man survived a horrific fall thanks to a feeling his twin is supposed to have had.GA more believable explanation is that，like any pair of people who have grown up together，they are just good at understanding the though procedures behind what their twin does.【语篇解读】本文是一篇说明文。虽然

28、许多双胞胎声称他们彼此知道对方所思所想，但没有证据表明这是因为他们有特殊的能力。他们只不过是善于理解各自行为背后的思维过程而已。1A由设空处上句可知，当一个卵子一分为二时，就会生出同卵双胞胎，从而生出两个具有相同基因的孩子；设空处下句又说，可是有些人认为，他们不仅仅外貌相似，而且思维方式也密切相关。所以只有A选项“我们都知道双胞胎在外貌上通常很相似。”切题。故选A。2G从意义上看，设空处上句“Although many identical twins claim to know what the other is thinking，there is no evidence to suggest

29、 that this is because of special powers.”说，尽管许多同卵双胞胎声称知道对方在想什么，但没有证据表明这是因为他们有特殊的能力。G选项“A more believable explanation is that，like any pair of people who have grown up together，they are just good at understanding the thought procedures behind what their twin does.”说，一个更可信的解释是，就像任何两个一起长大的人一样，他们只是善于理解各

30、自行为背后的思维过程而已；从结构上看，“前否后肯”是英文语义聚焦的一种典型手段，设空处上句出现了否定词no，G项除了有焦点副词just 以外，还有上句复数名词的回指代词they。综上故选G。3F由设空处上句“The media is full of stories in which a twin senses her brother or sister to be in trouble.”可知，媒体上充斥着双胞胎感觉到自己的兄弟或姐妹有麻烦的故事。故设空处应该是对该说法进行例举，F项“In a recent，widelyreported case，for example，a young man

31、 survived a horrific fall thanks to a feeling his twin is supposed to have had.例如，在最近一个被广泛报道的案例中，由于其孪生兄弟事前感知，一名年轻男子从一个可怕的坠落事件中幸存下来。”无论从逻辑意义还是结构形式上都切题。故选F。4D设空处上句“On the face of it，his sixth sense had saved the day.”说，从表面上看，是其第六感扮演了救命稻草的角色。只有D项“In truth，of course，the events might also be explained in

32、 more ordinary terms.当然，事实上，这些事件也可以用更平常的方式来解释。”切题，故选D。温馨提示：in fact/in truth，在语篇中，常常对于上文有“纠偏”的功能；这里还要注意焦点副词also的作用。此句话纠偏连带聚焦使文章段落的主旨更加突出。抓住这一点往往能事半功倍。5B设空处上句“Subconsciously concerned，he had just imagined the worstcase situation.”说，他下意识地感到担心，只是想到了可能发生的最坏的情况。只有B项“The fact that something awful had happe

33、ned was only a coincidence.其实某种可怕的事情的发生只不过是一种巧合而已。”意义上切题，结构上something awful与the worstcase situation相照应。故选B。温馨提示：本题从语篇结构上看与第四题很相似，The fact.is与上题中的in truth有类似意思，设空处上句及B项都分别含有一个焦点副词just与only。.语法填空The Forbidden City in Beijing，home to the Palace Museum，houses more than 1.8 million cultural relics and is

38、与cover为主动关系，故填covering。3widely考查词性转换。设空处应修饰known，故应使用副词形式。4its考查代词。设空处与下文中的preservation具有所有关系。故填形容词性物主代词its。5was displayed考查动词的时态及语态。由in 2005可知，该句应使用一般过去时。主语The painting与display为被动关系，故填was displayed。6a考查冠词。设空处后sight此处意为“看见的事物；景象；情景”，是可数名词。此处为“such冠词形容词名词”结构。故填不定冠词a。7countries考查名词复数。由设空处前面的other可知，填countries。8with考查固定搭配。 be familiar with意为“熟悉，了解”，故填with。9popularity考查词性转换。由设空处前面的形容词性物主代词its，可知设空处应填所给形容词popular的名词形式popularity。10whom考查定语从句。由句子结构可知，设空处所在部分是一个由“介词关系代词”引导的非限制性定语从句，由于先行词people为人，故填whom。
