39.D 主旨大意题。作者在本文中叙述了自己的室友Kate是一个非常有条理的人，而我是一个很没有规矩意识的人，东西总是乱放。后来我们两个人之间发生的一场冲突让我学会了去关心她，学会了要收拾整理自己的东西。学会了如何做一个室友。故D正确。 【长难句解析】
1.We could not have stayed together for a single minute but for a phone call. 【翻译】要不是一个电话，我们不可能能够在一起待一分钟。
【分析】本句是一个条件句的虚拟语气，但是它的条件并不是通过if条件句表示出来的，而是通过介词短语but for?要不是?；如果没有?.；该介词短语相当于if条件状语从句。 2.When she hung up, she quickly crawled under her covers, sobbing.
【翻译】当她挂完电话，她很快爬上了床，小声哭泣着。
【分析】本句中有一个when引导的时间状语从句，动词短语hang up表示挂断电话。后面的现在分词sobbing与句子主语she构成逻辑上的主动关系，所以使用现在分词做伴随状语。表示该动作与谓语动词同时发生。

false ideas about being fat and doing weight as they get older, while others
I‘ll never lose weight一I come from a fat family

You may experience mild discomfort as you begin to exercise regularly, but this is your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If they don’t, rest and seek medical advice.

The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid_we simply weigh too much， and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.
However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus，a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we，d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’
But fortunately there is an alternative ：cornflour. By adding enough of this common thickening agent to water (and it does take a lot)，you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.
Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink_and take a shower afterward!
44.Walking on water hasn’t become a reality mainly because humans______. A.are not interested in it B.have biological limitations C.have not invented proper tools D.are afraid to make an attempt
45.What do we know about Basilicus basilicus from the passage? A.It is light enough to walk on water.
B.Its huge feet enable it to stay above water. C.It can run across water at a certain speed.
D.Its unique skin keeps it from getting wet in water.
46.What is the function of the cornflour according to the passage? A.To create a thick liquid. B.To turn the water into solid.
C.To help the liquid behave normally. D.To enable the water to move rapidly.
47.What is the author’s attitude toward the idea of humans’ walking on water? A.It is risky but beneficial.
B.It is interesting and worth trying.
IC.t is crazy and cannot become a reality.
D.It is impractical though theoretically possible.

One moment it was quiet and calm in the forest, the next, the air was charged with tension. The elephant had heard the distant alarm calls of animals and her mood suddenly changed. I urged the elephant deeper into the forest. We sounded like a forest fire~crackling, snapping, trailblazing. But through all the noise came a sharp warning cry. The elephant stopped and we heard it again一the tell-tale call of a spotted deer.
I looked quickly around the shadows of the forest. Rays of sunlight shone through tree branches, beneath which the patchwork (交错）of green plants and shadows-within-shadows would make tiger stripes (条纹)look more attractive. Apart from an occasional noise from the elephant’s stomach, the forest was silent.
Gradually，the tension slipped from our bodies. The elephant seized a nearby branch and put it into her mouth. I reached forward and gently moved my hand over the elephant’s neck； there was a soft part，free of wrinkles and hairs，behind her ear.
This was my fourth time to sense the aura of the forest in Corbett，although I saw no tigers in the end. Located at the foot of the Himalayan mountains, Corbett is home to about 135 Bengal tigers, but the forest seemed to be guarding their whereabouts (出没处），a silent reminder of their
secrecy and rarity. Still, I was happy enough touching the elephant behind the ear. If I had so desperately wanted to see a tiger, I could have gone to a zoo. After all, spotting tigers merely confirms their beauty； tracking them can make you aware of something more. 48.Which of the following was a clear signal of alarm? A.The elephant stopped. B.A spotted deer called.
C.The elephant seized a branch. D.The forest was silent for a while.
49.The author begins his account of the tour in the forest mainly by . A.describing various sounds B.comparing different animals C.listing different activities D.introducing various plants
50.What does the underlined part “to sense the aura” most probably mean? A.To see the diversity. B.To enjoy the scenery. C.To feel the atmosphere. D.To experience the freedom.
51.How does the author feel after several visits to Corbett? A.Seeing a Bengal tiger is quite thrilling.
B.It is very time-consuming to travel in Corbett.
C.It is really worthwhile to study the animals in Corbett. D.The process of finding Bengal tigers is most appealing. 【考点】考察社会生活类阅读

50.C 推理题。根据本句可知作者已经是第四次来到corbett来感受森林，他不是来看风景的，也不是来看多种多样的动物（他可以去动物园），他是来体验森林里的氛围的。正是对森林里的这种很独特的氛围才让他一次次地来到这里。故C正确。
51.D 推理题。根据文章最后一句After all, spotting tigers merely confirms their beauty; tracking them can make you aware of something more可知作者认为来到这里看到老虎只会让你确认老虎是美丽的，但是追踪老虎会让感受到更多的东西。也就是让我更能够感受森林的氛围。故D正确。[ 【长难句解析】
