  剑桥雅思4Test4听力Section 4答案+解析

  谈话场景:学术报告。

  人物身份:主讲人为海洋动物。

  谈话话题:介绍澳大利亚鲨鱼的有关信息,其长度、重量、觅食习惯等,以及澳大利亚政府为防止鲨鱼攻击人类所采取的措施

  交际与语言表达

  1. 这部分讲述的是关于澳大利亚鲨鱼的场景,涉及到鲨鱼的生活习性、特征以及捕鲨网的来历和用途。

  2. “sharks vary in weight with size and breed…”鲨鱼的体重因大小和种类而不同。动词“vary”搭配介词“in”和“with”时,含义有区别,“vary in”表示“在……方面变化、不同”。例如:Rooms vary in size and come equipped with hairdryers, television and telephone. 房间大小不同,均配有吹风机、电视和电话。“vary with”表示“随着……变化而变化”,例如:Winds vary with time, altitude, and location. 风随时间、高度和位置的变化而变化。

  3. “This is made possible by their fins, one set at the side and another set underneath the body, and the tail also helps the shark move forward quickly.”它的鳍使快速游动成为可能,一个在一边,另外一个在身体下面,它的尾巴有助于鲨鱼迅速向前移动。“make possible”表示“使…变成可能”,例如:It is possible to make a hypothesis on the basis of this graph. 以这张图表为基础做出假设是可能的。“move forward”表示“向前移动,向前发展”,例如:Only by showing mutual respect can we move forward together. 在互相尊重的基础上,我们才可并肩向前。

  4. “They have a very acute sense of smell—and can sense the presence of food long before they can see it.”他们有敏锐的嗅觉,在看到食物之前就能感觉到它的存在。“sense of smell”表示“嗅觉”,例如:Man’s sense of smell is much less informative than his sight. 人的嗅觉远不如视觉提供的信息多。“sense of sight”表示“视觉”,“sense of humor”表示“幽默感”,“sense of honor”表示“荣誉感”。5. “It’s not that they think sharks are afraid of nets, or because they eat holes in them, because neither of these is true.”人们并不认为鲨鱼怕这些捕鲨网,或是鲨鱼在网上咬洞,因为这都不是事实。代词“it”指上一句的“有些人认为捕鲨网捕捉不是的方法”,第二个代词“they”指上一句中的”some people”,而第三个“they”则指代“sharks”,第四个代词“them”指“nets”。

  Question 31 795

  观察所给表格,可以预测到文章将会涉及到澳大利亚鲨鱼的情况,要求填的是关于重量、水中游泳的方式,以及觅食习惯。所以考生听到类似的信息时要格外注意。此题考查数字的听写,考生写阿拉伯数字就可。

  Question 32 tail

  原文提到“this is made possible by their fins, one set at the side and another set underneath the body, and the tail also helps the shark move forward quickly”(鲨鱼的鳍,一个在侧面,另一个在底部,使之成为可能;同时,鲨鱼的尾巴也能帮助鲨鱼更加快速地移动),所以此题填“tail”就可以了。

  Question 33 floor

  原文提到“mostly, they swim at the bottom of the ocean, scavenging and picking up food that’s lying on the ocean floor. ”(通常,它们在海底游弋,以沉在海底的腐烂食物为食),所以此题填“floor / bottom / bed”均可。

  Question 34 sense of smell

  原文提到“they have a very acute sense of smell”(它们有着非常敏锐的嗅觉),所以此题填“sense of smell”就可以了。

  Question 35 A

  首先注意此题题干中提到的“meshing”一词的意思是“用网捕捉,落网”。原文提到“meshing involves setting large nets parallel to the shore”(用网捕捉包括在沿海岸线铺设大规模的鱼网),所以此题选A。

  Question 36 A

  原文提到“The New Zealand authorities also looked at it, but considered meshing uneconomical—as did Tahiti in the Pacific. At around the same time, South Africa introduced meshing to some of its most popular swimming beaches. ”(新西兰政府也考察过,但是认为这种方法经济上不划算——太平洋上的塔希提岛也持同样观点。同时,南非把这种方法应用到了其游人最多,的一些海滩上。)所以,此题应该排除选项B 和C,要选择。

  Question 37 B

  原文中提到“When meshing began, approximately fifteen hundred sharks were caught in the first year. However, this declined in the years that followed, and since that time, the average annual catch has been only about a hundred and fifty a year.”这句话提到了两个数字,1500 对应的是年捕获鲨鱼的数量,而题干中问的是如今每年被鲨鱼网困住的鲨鱼的数量,所以答案为150,即B 选项。

  Question 38 B

  原文提到“the majority of sharks are caught during the warmest months, form November to February”(大多数的鲨鱼都是在最温暖的月份被抓住的,从11 月到2 月),考生应该注意到南半球澳大利亚的夏天正是北半球的冬天,所以此题应该选B。此题也是出题人故意设计的考点。

  Questions 39- 40 B, E

  这两个题要求考生挑出使“shark nets”减少作用的选项。原文提到“But meshing does appear to be less effective than some other methods, especially when there are big seas with high rolling waves and strong currents and anything that lets the sand move”(但是在某种程度上,比起其他方法来说,用网捕捉这个方法的效果并不那么明显,尤其是当有大浪和强流的时候,以及沙流动比较厉害的时候),所以应该选B 和E。
