evanescenceThe 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, veral types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicuskiss 因为是女子，a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of veral meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per cond 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 thicken
ing agent to water (and it does take a lot)matter of fact，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 ca you start to sink_and take a shower afterward!

【考点】考察科普知识类阅读
【文章大意】人类一直都希望能够达到草上飞的境界。文章中叙述了使用cornflour在水面上产生一层，让我们能够在水上奔跑的新的理论，虽然在理论上可行，但是并不实际。
44.B 推理题。根据文章第2行：accordWe simply weigh too much, and all our mass push down through our relatively small feet.可知我们人类太重 了，我们的身体把太多的重量都加到了我们的脚上，带来了太多的压力，让我们会沉下去。故B正确。
45.C 细节题。根据第二段第4hypothesis什么意思行：The lizard will take as many as 20 steps per cond to keep moving forward。可知这种蜥蜴可以在水面之上连续奔跑一段距离而不沉到水里。故
C正确。
46.A 推理题。根据文章第三段第2,3行：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 …可知这种cornflour会让水面上形成一个很厚的表层。故A正确。

47.D 推理题。根据文章倒数第三行Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice。可知这种做法仍然只是停留在理论上，并不能在实际上有应用。说明作者认为这是不实际的。故D正确。
ie是什么意思
【长难句解析】
dato1.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.
【翻译】通过向水面添加一些这样的常见的东西，你会创造出一种不同于正常的水的非牛顿规律的液体。
【分析】本句中的介词by表示通过某种手段或方法，后面要接动名词短语做宾语。同时本句中有一个定语从句that doesn’t behave like normal water.修饰前面的先行词liquid。
2.Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice.
【翻译】尽管所有这些听起来很有趣，但是这仍然只是理论上更好一点，而不是实际执行。
【分析】本句中的Fun though all this may sound是一个形式倒装，相当于一个让步状语从句Though all this may sound fun。

It’s generally believed that people act the way they do becau of their personalities and attitudes. They recycle their garbage becau they care about the environment. They pay S5 for a caramel brul6e latte becau they like expensive coffee drinks.
It’s undeniable that behavior comes from our inner dispositions (性情），but in many instances we also draw inferences about who we are, as suggested by the social psychologist Daryl Bern, by obrving our own behavior. We can be strangers to ourlves. If we knew our own minds，why would we need to guess what our preferences are from our behavior? If our minds were an open book, we would know exactly how much we care about the environment or like lattes. Actually，we often need to look to our behavior to figure out who we are.
