Sadly, biological facts prevent us ever accomplishing such a thing without artificial
10、 aidwe 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
11、 and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the waters surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, wed need huge feet that we could bring up to our
12、ears in order to create adequate “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 “nonNewtonian” liquid that doesnt behave like normal water. Now, if the surface of the water is hit hard
13、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, its still rather messy and better rea
14、d about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sinkand take a shower afterward!1. Walking on water hasnt become a reality mainly because humans_.A. are not interested in itB. have biological limitationsC. have not invented prop
15、er toolsD. are afraid to make an attempt2. 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.3. What is t
16、he 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.4. What is the authors attitude toward the idea of humans walking on water?A. It is risky but beneficial.B. I
17、t is interesting and worth trying.C. It is crazy and cannot become a reality.D. It is impractical though theoretically possible.答案与解析本文为说明文，题材为科普知识类。能在水上行走是人类一直以来感兴趣的话题，虽然有方法能实现这一想法，但所有这些都只是理论上的，并不切合实际。1B细节理解题。根据第一段的 Sadly, biological facts prevent us.可知是人类自身生理结构的限制阻止了我们在水上行走，所以答案为B项。2C细节理解题。根据第二段中的
18、 The lizard will take as many as 20 steps per second to keep moving forward.可知这种蜥蜴是通过保持一定的前进速度确保自己能在水上前行的，所以答案为C项。3A细节理解题。根据第三段的最后一句话中的 the surface of an adequately thick liquid of cornflour 可知，cornflour 的作用就是创造出一种足够厚的液面让我们能够在上面行走，所以答案为A项。4D观点态度题。根据最后一段的描述：这个听起来可能很有趣，但是要想付诸实践还是不太实际，所以答案为D项。.完形填空“Mum

28、ect Csuspect D. accept答案与解析本文为记叙文。题材为家庭生活类。詹姆斯想邀请同学来家里，然而他母亲却不同意，在詹姆斯的说服下，母亲终于答应了他的要求。1C詹姆斯想请同学来家里的原因是他们没有家庭作业，故答案为C项。2A根据倒数第二段中 Dad opened his eyes 及本句中resting his head on his arms 可推知父亲已经睡着了，故答案为A项。3B母亲可以看出詹姆斯非常想让他的朋友过来。A.解释；B.看出，明白；C.同意；D.怀疑。4B妈妈拒绝了他的请求，又根据詹姆斯所说的话(Im never allowed to have friends
29、 come to the house? Why，Mum？)，可判断詹姆斯很伤心，几乎要哭了，故答案为B项。5D首先要弄清本句中的 it 指的是詹姆斯所说的“never allowed to have friends come to the house”由此可见母亲认为：从不让朋友到家来对于詹姆斯来说是很难的。A.公平的；B.容易的；C.好的，有好处的；D.艰难的。6A根据上段中的“.other people might think were a little.strange.”可知本题答案为 strange。7A说实话，詹姆斯，我的脖子一直非常疼痛以至它使我的头疼得很厉害。A.头疼；B.损失；
30、C.任务；D.白天。8D根据下文 He really needs a rest：可知这里表示：父亲也感觉不舒服。well 作形容词时，意为：in good health 健康。A.生病的；B.好笑的，有趣的；C.感到难过的。9B根据语境可知设空处后的句子(I can.better)表示条件，故答案为B项。10C他冲到厨房的抽屉那里找到了他想要的东西两个扳手。A.保持；B.控制；C.找到；D.还回。11C根据下段中的 Dad had tightened your neck bolts(螺栓) too much！可知本空表示詹姆斯对母亲进行了修理，故答案为C项。12B根据本句中的 smile 可推
31、知他对自己的工作很满意，故答案为 satisfaction。A.怜悯；B.满意；C.痛苦；D.礼貌。13D根据本句中的 easy 可推知答案为：骄傲地。詹姆斯骄傲地说：“那很容易。”14A根据 Dad had tightened your neck bolts(螺栓)too much 可推知詹姆斯只是调整了一下脖子上的螺栓，故答案为A项。A.调节；B.收集；C.生产；D.覆盖。15C母亲现在感觉舒服多了，于是请求詹姆斯去帮一下他父亲，故答案为C项。16A在 plugged the electric wire 之前，需把父亲的头发撩起来，故答案为 lifted(抬起，撩起)。B.抓住；C.给；D

36、on of thrift will never fade.答案与解析本文为演讲稿。主题是：厉行节约。1has become根据下文可推知：目前浪费已经成为校园里常见的现象，故本空需用现在完成时态。2left本题考查非谓语动词作定语。leave 与被修饰词 much 为逻辑上的被动关系，故用 leave 的过去分词形式作定语。3others根据 Some 可推知本空填 others。4running本空考查非谓语动词作宾补。宾语 water 与 run 之间为逻辑上的主动关系，且表示正在进行，故用 run 的现在分词形式。5without句意：每天学生们不注意电扇是否关闭了就离开了教室。设空处后
37、为ing 形式，故可判断设空处应为介词，根据句意此处应填without。6that本句的主干为：Has thrift gone？其中的“one of the most national traditions_6_developed from our long history”作 thrift 的同位语；在该同位语中“_6_developed from our long history”为定语从句，先行词为 the most national traditions，关系词在定语从句中作主语，先行词被形容词最高级形式修饰，故用 that 引导，而不用 which。7If句意：如果那样的话，那把它找
38、回来吧！if so：如果那样的话。8shortage介词(in)后需用名词形式，故答案为 shortage。water 作 shortage 的定语。9to read在贫困地区，孩子们为了读书分享一盏昏暗的灯。设空处作目的状语，故用不定式形式。10our句意：感谢我们可以使用的纸张，因为很多树木被砍伐是为了满足我们(对纸张)的需要。.短文改错Today, my foreign teacher Tim and I went to the Peoples Park together.
