    The fiddler crab (蟹) is a living clock. It shows the time of day by the colour of its skin, which is dark by day and pale by night. The crab’s changing colour follows a regular twenty—four hour plan that exactly matches the daily rhythm of the sun.
    Does the crab actually keep time, or does its skin simply answer to the sun’s rays, changing colour according to the amount of light strikes it? To find out, biologists kept crabs in a dark room for two months. Even without daylight, the crab’s skin colour continued to change exactly on time.
    This characteristic probably developed gradually in answer to the daily rising and setting of the sun, to help protect the crab from sunlight and enemies. After millions of years it has become completely regulated (受控制) inside the living body of the crab.
    The biologists noticed that once each day the colour of the fiddler crab is especially dark, and that each day this happens fifty minutes later than on the day before. From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides (潮水). The crab’s period of greatest darkening is exactly the time of low tide on the beach where it was caught!
    小题1:The fiddler crab is like a clock because it changes colour ______.
    A in a regular 24—hour rhythm              B. in answer to the sun’s rays
    C. at low tide                            D. every fifty minutes
    小题2:The crab’s changing colour ______.
    A.tells the crab what time it isB.protects the crab from the sunlight and enemies
    C.keeps the crab warmD.is of no real use
    小题3: When the fiddler crabs were kept in the dark , they ______.
    A.did not change colourB.changed colour more quickly
    C.changed colour more slowlyD.changed colour on the same timetable
    小题4:The crab’s colour—changing ability was probably developed ______.
    A.in the process of evolution (进化)B.over millions of years
    C.by the work of biologistsD.both A and B
    小题5:The best title for this selection would be ______.
    A.The Sun and the TidesB.Discoveries in Biology
    C.A scientific StudyD.A Living Clock

  • 日常生活类阅读

日常生活类阅读的概念:

日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作,生活以及学习情况。做这一类题时,最主要的是要把握好人物的活动内容,时间和地点。


日常生活类阅读题答题技巧:

【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小,追根溯源,探索各项风俗的历史渊源,内容有趣。命题也以送分题为主,如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松,试题做起来比较顺手,但绝不能掉以轻心。因为稍不留神,就会丢分。   
【备考提醒】
为了保证较高准确率,建议同学们做好以下几点:   
1、保持正常的考试心态。笔者在教学中发现,越是容易的试题,同学们越是容易失分。为什么呢?因为在这种情况下,同学们极易产生麻痹思想,认为题目好做,就不引起高度重视,于是思维不发散、不周密。而命题人就是利用同学们的这一弱点,设计陷阱题。所以,无论试题难易与否,我们都要保持正常的考试心态。试题容易,不欣喜;试题难,不悲观。   
2、根据前面讲到的方法,认认真真、细细心心做好事实细节题。   
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义,确定多义词或短语在文中的意思,确认文中的某个代词所指代的对象,或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子,切不可望文生义。   
4、做好简单推理判断题。简单推理判断题要以表面文字为前提,以具体事实为依据进行推理,做出判断。这种推理方式比较直接,只要弄清事实,即可结合常识推断出合理的结论。
