    According to the passage, “They don’t talk the same language” (Paragraph 1), can refer to problems in ______.
    A

    understanding metaphor.

    B

    learning foreign languages.

    C

    understanding dialect or style.

    D

    dealing with technological change.


    正确答案： A
    解析：
    题干中已经明确指出答案出自第一段，因此根据题干关键词They don’t talk the same language可定位到最后一句“‘They don’t talk the same language’ has a major metaphorical meaning alongside its literal one”, 可知本题考查的应该是这句话的隐喻意思，因此应该在第一段中进行概括总结，这时会发现倒数第二句“‘Common language’ here usually means a foreign language, but the same point applies in principle to any encounter with unfamiliar dialects or styles within a single language”，意思是“共同语言指的是一门外语，但是说同一语言下的不熟悉的方言或文体内也会有类似的问题”，由此可知，这里They don’t talk the same language应该理解为在方言和文体上存在的问题。该句先是说通常情况下，所以该题选C。

    Which of the following can be inferred about the effect of direct sunlight on lichens?
    A

    It damages the algae.

    B

    It helps the fungi absorb water.

    C

    It is required for the algae to carry on photosynthesis.

    D

    It destroys the fungi.


    正确答案： A
    解析：
    推断题。第二段第五句指出“The fungi provide support, absorb water, and shelter the tender algae from direct sunlight.”（真菌为藻类提供支持，吸收水分，并为稚嫩的藻类提供遮护使其免受阳光的直射），从侧面反映出直射的阳光会对藻类造成损害，因此选A。

    you are patient

    B

    you obey all the traffic rules

    C

    you don’t cut another car off

    D

    you wait in line at a red light


    正确答案： A
    解析：
    事实细节题。由关键词safe定位最后一段，作者提到安全驾驶的前提是遵守交通规则，故B项正确。A项“要耐心”原文没有提及。C项 “不要从别的司机面前横过”，D项 “遇到红灯时要排队等候”均不够全面。

  • 第11题：

    单选题
    Why does the author say that “these species of fungi seem rather strange”?
    A

    They are larger than typical fungi.

    B

    Unlike other fungi, they can produce their own food.

    C

    They exist only as partners of algae.

    D

    They do not fit into any known class of fungi.


    正确答案： B
    解析：
    细节题。该引用部分出现在最后一段倒数第二句，可推测前文会出现相关内容。第二段倒数第二三句指出“藻类是公认的能独自生长的物种；而另一方面，真菌没有同伴却无法生存”，由此可知真菌是依赖同伴即藻类而生存的，因此如果将它们分别进行分类，真菌物种就会显得格外奇怪。因此选项C为正确答案。

    正确答案： A
    解析：
    从文章首段可看出Jerome与妻子品位不同，并且不喜欢她来干涉他；接下来一段描述了Jerome妻子长得比较粗俗；而最后一段提到Jerome是一个安静的教师，并且比妻子小10岁，可见他们两人差距很大，因此B项“他们的婚姻并不和谐”符合文章内容。

    正确答案： C
    解析：
    推理题。本题为反选题。原文第四段的前两句话说到：So we enjoyed Mrs. Orr’s cake with white icing twice a year. Nothing fancy, nothing pretentious—just like Dad.可见，作者将父亲比作朴实无华的蛋糕，说明了父亲务实的性格，故B选项的说法正确，可排除。原文第三、五两段的段末，均出现了silly question一词，来表明作者觉得句没自己必要提出前面的问题，同时也说明了父亲固执不愿意改变的性格，故C选项的说法正确，可排除。原文第五段第一句话中的generous一词说明父亲慷慨大方性格，故D选项的说法也是正确的，也可排除。而A选项“苛求的”在原文中并没有体现，因此本题正确答案为A。
