Oh,我觉得你大概是读到最后人晕了. Fine,我们来看看题目先吧
插入的句子:
Because the internal signals that regulate waking and going to sleep tend to align themselves with these external cues, the external clock appears to dominate the internal clock.
要插入的段落:
Animals need natural periodic signals like sunrise to maintain a cycle whose period is precisely 24 hours. ■Such an external cue not only coordinates an animal's daily rhythms with particular features of the local solar day but also—because it normally does so day after day-seems to keep the internal clock's period close to that of Earth's rotation. ■Yet despite this synchronization of the period of the internal cycle, the animal's timer itself continues to have its own genetically built-in period close to, but different from, 24 hours. ■Without the external cue, the difference accumulates and so the internally regulated activities of the biological day drift continuously, like the tides, in relation to the solar day. ■This drift has been studied extensively in many animals and in biological activities ranging from the hatching of fruit fly eggs to wheel running by squirrels. (以下省略)
-------------------------------------------------------------------
从要插入的句子入手:(因为无论你选ABCD都是要看这句话的,所以..读明白)Because the internal signals that regulate waking and going to sleep tend to align themselves with these external cues, the external clock appears to dominate the internal clock.
化简: 因为internal signals常常和these external 联系在一起,所以external 就占上风了
关键词:internal signals, align, these external cues(多好啊!有指代的), dominate
插入段落:
S1.Animals need natural periodic signals like sunrise to maintain a cycle whose period is precisely 24 hours. 化简:动物需要24小时的cycle
S2.Such an external cue not only coordinates an animal's daily rhythms with particular features of the local solar day but also—because it normally does so day after day-seems to keep the internal clock's period close to that of Earth's rotation.
Well, 你觉得这个句子里的not only but also是个什么结构?并列?
不是并列!是强调哦!而且一般在not only but also结构中强调的都是but also之后的部分,所以but also之后的内容要读明白哦~ 其实这就是T的高明之处,T不专门考语法,但是又处处是grammar.但我们要明白,无论是什么样的考点,考的都是有没有读明白要求的段落,千金难买明白二字呀!!平时练习读懂比读多读快要重要,因为你练习的时候不明白的在考试的时候更加明白不了;考试的时候读多读快更重要,因为做不完多少就木有多少分了.啊..跑题了.我们看化简之后的句子理解.
化简:an external cue不仅使得动物日间节律与太阳一致,还使得internal period与地球自转接近
S3.Yet despite this synchronization of the period of the internal cycle, the animal's timer itself continues to have its own genetically built-in period close to, but different from, 24 hours.
See!上句考强调,这句开始考转折了,看到这里的时候有没有晕掉?没晕,好样的!晕了,拍醒了扶起来!
首先看到句首的Yet,表明下面开始转入另一个方向,或者就直接理解为开始不一样了.
然后看到despite,让步状语标志性词汇,oh!强调又来了!不明白为什么这里又是强调?来看一下这个描写Ben神的句子:Though he has got a common face, he got a full mark in the GRE. [他虽然有一张大众脸,但GRE拿了满分.]如果让你看完这个句子,去跑个4公里,然后回来问你记得什么,多半答案都是他拿了满分对不对?(如果你只记得大众脸..sigh..那也太以貌取人了有木有)So!! Here it is:让步其实就是一种变相的强调,让掉不重要的(或者前文已经说过的),强调后面重要的(或者没说过的新观点). 所以, 这句话的重点在于后半句,前半句的事实上已经是上文讲述过的内容了. 还有读的时候注意:genetically built-in=internal, period=cycle, 所以我们得到一下化简的句子理解
化简:但是,尽管(internal cycle的同时化,我自己做题一般就直接XXX代替),动物的timer还有一种内在的cycle,这种cycle和24h相近却又有所不同.
S4.Without the external cue, the difference accumulates and so the internally regulated activities of the biological day drift continuously, like the tides, in relation to the solar day.
drift在这里是个verb.
化简:如果没有了external, difference就会积累下来,biological day 的 internal regulated activities 随着solar day(像潮水一样)不断变化(drift).
S5.This drift has been studied extensively in many animals and in biological activities ranging from the hatching of fruit fly eggs to wheel running by squirrels.
化简:这个drift已经被详细研究过了.
此句和前面一句与我们插入的句子完全没有关系,D排除.
-------------------------------------------------------------------
当读完了的时候,再回头看看,是不是发现A已经不能选了呢?
原因:
1.s1没有提到external/internal
2.s1实际上是一个事实陈述,插入句也是是一个事实陈述,代入之后完全就不知道两个事实之间有什么关系
-->>排除A
好了,我们只剩下BC了,这里就很明显选B了
C有很明显的劣势:S4说了without evternal cue下的情况,但是!我们插入的句子是external dominate的结论.想想看,如果我们先说,我们的革命运动取得了压倒性的胜利!然后说,没有了革命运动我们也活得很好.就算是体育老师也会想剁了我们的.So, C排除.
Why B?
1.指示代词these有着落了(其实光靠指示代词就可以排掉AD,但是我觉得对于楼主一样的green hand还是解释详细一点比较好)
2.事实上S2是一个对插入句中dominate的解释,插入句提供一个小结论(或者说是事实更准确),s3是要开始转折,但注意这里的转折还是在插入句基础上的,也就是说S2与S3都与插入句相关,选B
-------------------------------------------------------------------
嗯,我也是26号考T.希望这次能刷110+,enter my dream school. 祝我们好运!
对了,下次问问题记得把题目和相应的文段贴出来,至少写一下是TPO的第几篇,题号是多少.这样看到的人能够减少在找原题用的时间,快速得到回答的几率会比较高.
