1、 2022年2月GMAT考试逻辑真题（至2.22）（一）1 升桥问题V1说一个地方有那种为了过船可以升起来的桥，政府说神马要改建，让更大吨位的船能够通过，然后还说这样还能够环节汽车交通的问题，问减弱?我好像做错了，有一个是升桥原来一个人来操作，现在三个人;还有一个是和船是否选择走这个桥下面有关，详细怎么说的忘了。V2说一个地方有那种为了过船可以升起来的桥，政府说神马要改建，让更大吨位的船能够通过，然后还说这样还能够环节汽车交通的问题，问减弱?参考选项：升桥原来一个人来操作，现在三个人和船是否选择走这个桥下面有关。 这个我记得的东西也就和原JJ上的一样了。考古1V1(710,v36) 说一个地方
2、要把原来的bridge拆掉，修一个新的。然后说预备把这个bridge修的比原来高，宽度比原来大。这样在许多大船通过的时候就不用把桥吊起来(吊起来再放下这个过程要花一个小时，期间桥上无法通车)了。问这个新桥为什么不能起到提高交通效率的作用。我选的答案是：由于桥建的比以前宽了，以前走不过去的大船现在可以通过了，所以要把桥吊起来的状况有可能不会削减。V2(730,V38) 描述一种跨河大桥可以抬起来让船过去。说现在要把旧的移除建立个新桥。新桥可以削减由于抬桥造成的交通堵塞，cause它更高更宽。问减弱，a选项说抬桥之前会停顿交通一小时以待观看之类不是很确定V3(720,V36) 大桥通船那个，选了C
3、，有些otherwise怎么的船大桥改造了以后都去了V4(770,V44) 我选了会把更大的船吸引过来。想了好久。不确定2 咖啡因binding讲大脑分泌一种神马物质能够binding到一个神马细胞之类的东西上，binding多了人就会weakness，然后就想睡觉，说睡完了就binding少了，然后有人就说什么binding是sleep的缘由，问支持?狗爸选的是咖啡能够削减binding，从而起到不让人想睡觉的目的考古2GWD25-Q36The chemical adenosine is released by brain cells when those cells are active.
4、 Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of a
5、denosine to a large number of sites that causes the onset of sleep.Which of the following, if true, provides the most support for the researchers hypothesis?A. Even after long periods of sleep when adenosine is at its lowest concentration in the brain, the number of brain cells bound with adenosine
6、remains very large.B. Caffeine, which has the effect of making people remain wakeful, is known to interfere with the binding of adenosine to sites on brain cells.C. Besides binding to sites in the brain, adenosine is known to be involved in biochemical reactions throughout the body.D. Some areas of
7、the brain that are relatively inactive nonetheless release some adenosine.E. Stress resulting from a dangerous situation can preserve wakefulness even when brain levels of bound adenosine are high.b争论：背景：物质A有一个特点BB多了人睡觉，睡完了B少;结论：B是睡觉的缘由分析：从现象推到一个结论既然要支持B是睡觉的缘由，那么就要说明: B多人睡觉(题中消失)，B少人不睡觉(推理中缺失)答案：补足推理中缺失的一环是咖啡能够削减binding，从而起到不让人想睡觉的目的(疑似)
