雅思听力marine真题 雅思听力课堂开场白

雅思听力课堂开场白是什么样的?需要讲究些什么?大家都很想知道吧，下面我就给大家分享一下，希望大家喜欢!

雅思听力课堂开场白

第一堂课是老师在学生面前建立第一印象的关键时刻，对于老师建立威性的意义不言而喻。一般说来，如果老师能在最开始的4小时教学中让学生信服，学生会在以后的整个教学过程中对老师产生很强的信赖，几乎会言听计从，这对于教学的顺利进行将非常有帮助。

在第一堂课上，老师必须向学生明确：

1、这个阶段的学习目的是什么。

每个阶段中的教学任务和教学重点是不一样的，一个个阶段的合理连接和衔接使得学生步步为营，不断提高。

§ 基础阶段更强调对于基本的词汇、语法知识补充;

§ 预备阶段，则让学生开始熟悉考试的题型和听力场景;

§ 精品阶段开始详细讲解考试的技巧，并针对题型和技巧做专项练习;

§ 高分阶段则通过大量的真题模拟联系，对于技巧进行进一步的强化和巩固。

2、老师会通过什么样的方式帮助你们达到这样的学习目的;

建议老师把所需用到的教材以及补充教材介绍给学生，并推荐相应的课外练习，方便不同程度的学生进行课后自学;

3、描述他们可能遇到的困难;

每个阶段中学生都会遇到不同的困难，如果对于困难没有足够的估计，他们真正遇到困难时很容易产生畏难情绪，并打退堂鼓。老师可以根据自己的教学 经验 ，对于学生通常遇到的困难进行描述，并给出相应的建议。这样可以增加学生对老师的信赖，也能增加学生对学习过程的认识。

4、提出对学生的要求;

教和学永远是相辅相成的过程。老师讲解的每一个技巧或者 方法 ，都需要学生的配合和理解才能够变成学生自身对解题和英语提高有用的知识。目前，很多学生觉得教学效果不明显的一个相当重要的原因就是，他们不知道在课后(甚至课上)除了听老师讲以外，他们还需要做些什么。建议老师在第一节课就明确希望学生所做的配合。无论是纪律方面，还是完成课后作业方面，还是词汇等课后的自行巩固等。

5、做适当的针对性的鼓励。

由于之前提出了很多困难和鼓励，老师也要对学生进行适当的鼓励。可以拿以前教学中成功的例子鼓舞新的学生，告诉他们，只要有好的方法和恒心，雅思考试实在只是小菜一碟。

同时，可以采取先破后立的方法，先纠正学生一些常见的错误习惯或方法，或与他们分享自身英语提高的经验，一可以学生觉得老师非常了解他们，二可以通过自身的例子拉近与学生之间的距离。

在教学过程中，学生常会问到其他关于 英语学习 的问题，比如如何背单词，如何写 作文 ，如何提高口语水平等让老师无法用一句话回答的问题。此时要给出某种具体可行(最好又很新颖)的操作才能让学生心悦诚服。学生不想听长篇大论，更不能用一些老生常谈的东西敷衍他们，他们需要的是具体而有效的形式。

当然，要告诫学生，如果没有毅力，所有的方法都是空谈。

此外，老师可以对于近期考试的信息稍作分析。对雅思最新动态的了解，也是让学生信赖你的资本。

老师要帮着学生琢磨考试的出题思路，要知道雅思出题者经常在哪儿挖陷阱又在哪儿会送分给你，学生最爱听老师对出题者的心理分析，这样会觉得很有把握。

The Origins Of Cetaceans

It should be obvious that cetaceans-whales, porpoises, and dolphins-are mammals. They breathe through lungs, not through gills, and give birth to live young. Their streamlined bodies, the absence of hind legs, and the presence of a fluke1 and blowhole2 cannot disguise their affinities with land dwelling mammals. However, unlike the cases of sea otters and pinnipeds (seals, sea lions, and walruses, whose limbs are functional both on land and at sea), it is not easy to envision what the first whales looked like. Extinct but already fully marine cetaceans are known from the fossil record. How was the gap between a walking mammal and a swimming whale bridged? Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans.

Very exciting discoveries have finally allowed scientists to reconstruct the most likely origins of cetaceans. In 1979, a team looking for fossils in northern Pakistan found what proved to be the oldest fossil whale. The fossil was officially named Pakicetus in honor of the country where the discovery was made. Pakicetus was found embedded in rocks formed from river deposits that were 52 million years old. The river that formed these deposits was actually not far from an ancient ocean known as the Tethys Sea.

The fossil consists of a complete skull of an archaeocyte, an extinct group of ancestors of modern cetaceans. Although limited to a skull, the Pakicetus fossil provides precious details on the origins of cetaceans. The skull is cetacean-like but its jawbones lack the enlarged space that is filled with fat or oil and used for receiving underwater sound in modern whales. Pakicetus probably detected sound through the ear opening as in land mammals. The skull also lacks a blowhole, another cetacean adaptation for diving. Other features, however, show experts that Pakicetus is a transitional form between a group of extinct flesh-eating mammals, the mesonychids, and cetaceans. It has been suggested that Pakicetus fed on fish in shallow water and was not yet adapted for life in the open ocean. It probably bred and gave birth on land.

Another major discovery was made in Egypt in 1989. Several skeletons of another early whale, Basilosaurus, were found in sediments left by the Tethys Sea and now exposed in the Sahara desert. This whale lived around 40 million years ago, 12 million years after Pakicetus. Many incomplete skeletons were found but they included, for the first time in an archaeocyte, a complete hind leg that features a foot with three tiny toes. Such legs would have been far too *all to have supported the 50-foot-long Basilosaurus on land. Basilosaurus was undoubtedly a fully marine whale with possibly nonfunctional, or vestigial, hind legs.

An even more exciting find was reported in 1994, also from Pakistan. The now extinct whale Ambulocetus natans ("the walking whale that swam") lived in the Tethys Sea 49 million years ago. It lived around 3 million years after Pakicetus but 9 million before Basilosaurus. The fossil luckily includes a good portion of the hind legs. The legs were strong and ended in long feet very much like those of a modern pinniped. The legs were certainly functional both on land and at sea. The whale retained a tail and lacked a fluke, the major means of locomotion in modern cetaceans. The structure of the backbone shows, however, that Ambulocetus swam like modern whales by moving the rear portion of its body up and down, even though a fluke was missing. The large hind legs were used for propulsion in water. On land, where it probably bred and gave birth, Ambulocetus may have moved around very much like a modern sea lion. It was undoubtedly a whale that linked life on land with life at sea

Fluke: the two parts that constitute the large triangular tail of a whale

托福TPO2Part2阅读题目

Directions: Mark your answer by filling in the oval next to your choice.

1. In paragraph 1, what does the author say about the presence of a blowhole in cetaceans?

It clearly indicates that cetaceans are mammals.

It cannot conceal the fact that cetaceans are mammals.

It is the main difference between cetaceans and land-dwelling mammals.

It cannot yield clues about the origins of cetaceans.

2. Which of the following can be inferred from paragraph 1 about early sea otters?

It is not difficult to imagine what they looked like

There were great numbers of them.

They lived in the sea only.

They did not leave many fossil remains.

Paragraph 3: The fossil consists of a complete skull of an archaeocyte, an extinct group of ancestors of modern cetaceans. Although limited to a skull, the Pakicetus fossil provides precious details on the origins of cetaceans. The skull is cetacean-like but its jawbones lack the enlarged space that is filled with fat or oil and used for receiving underwater sound in modern whales. Pakicetus probably detected sound through the ear opening as in land mammals. The skull also lacks a blowhole, another cetacean adaptation for diving. Other features, however, show experts that Pakicetus is a transitional form between a group of extinct flesh-eating mammals, the mesonychids, and cetaceans. It has been suggested that Pakicetus fed on fish in shallow water and was not yet adapted for life in the open ocean. It probably bred and gave birth on land.

3. The word precious in the passage is closest in meaning to

Exact

Scarce

Valuable

Initial

4. Pakicetus and modern cetaceans have similar

Hearing structures

Adaptations for diving

Skull shapes

Breeding locations

5. The word it in the passage refers to

Pakicetus

Fish

Life

ocean

Paragraph 4: Another major discovery was made in Egypt in 1989. Several skeletons of another early whale, Basilosaurus, were found in sediments left by the Tethys Sea and now exposed in the Sahara desert. This whale lived around 40 million years ago, 12 million years after Pakicetus. Many incomplete skeletons were found but they included, for the first time in an archaeocyte, a complete hind leg that features a foot with three tiny toes. Such legs would have been far too *all to have supported the 50-foot-long Basilosaurus on land. Basilosaurus was undoubtedly a fully marine whale with possibly nonfunctional, or vestigial, hind legs.

6. The word exposed in the passage is closest in meaning to

Explained

Visible

Identified

Located

7. The hind leg of Basilosaurus was a significant find because it showed that Basilosaurus

Lived later than Ambulocetus natans

Lived at the same time as Pakicetus

Was able to swim well

Could not have walked on land

8. It can be inferred that Basilosaurus bred and gave birth in which of the following locations

On land

Both on land and at sea

In shallow water

In a marine environment

Paragraph 5: An even more exciting find was reported in 1994, also from Pakistan. The now extinct whale Ambulocetus natans ("the walking whale that swam") lived in the Tethys Sea 49 million years ago. It lived around 3 million years after Pakicetus but 9 million before Basilosaurus. The fossil luckily includes a good portion of the hind legs. The legs were strong and ended in long feet very much like those of a modern pinniped. The legs were certainly functional both on land and at sea. The whale retained a tail and lacked a fluke, the major means of locomotion in modern cetaceans. The structure of the backbone shows, however, that Ambulocetus swam like modern whales by moving the rear portion of its body up and down, even though a fluke was missing. The large hind legs were used for propulsion in water. On land, where it probably bred and gave birth, Ambulocetus may have moved around very much like a modern sea lion. It was undoubtedly a whale that linked life on land with life at sea

9. Why does the author use the word luckily in mentioning that the Ambulocetus natans fossil included hind legs?

Fossil legs of early whales are a rare find.

The legs provided important information about the evolution of cetaceans.

The discovery allowed scientists to reconstruct a complete skeleton of the whale.

Until that time, only the front legs of early whales had been discovered.

10. Which of the sentences below best expresses the essential information in the highlighted sentence in the passage?

Incorrect choices change the meaning in important ways or leave out essential information.

Even though Ambulocetus swam by moving its body up and down, it did not have a backbone.

The backbone of Ambulocetus, which allowed it to swim, provides evidence of its missing fluke.

Although Ambulocetus had no fluke, its backbone structure shows that it swam like modern whales.

By moving the rear parts of their bodies up and down, modern whales swim in a different way from the way Ambulocetus swam.

11. The word propulsion in the passage is closest in meaning to

Staying afloat

Changing direction

Decreasing weight

Moving forward

Paragraph 1: Extinct but already fully marine cetaceans are known from the fossil record. ■How was the gap between a walking mammal and a swimming whale bridged? ■Missing until recently were fossils clearly intermediate, or transitional, between land mammals and cetaceans.■Very exciting discoveries have finally allowed scientists to reconstruct the most likely origins of cetaceans. ■In 1979, a team looking for fossils in northern Pakistan found what proved to be the oldest fossil whale.

沙漠已经占据了地球表面积约四分之一，而且最近几十年正以惊人的速度扩张。沙漠化是指类似沙漠的环境漫延到原本并非沙漠的区域。据估计，地球表面另外四分之一的地方正面临沙漠化威胁。

沙漠化主要通过以下过程实现：首先自然植被不断减少，随后风力和 雨水 加速了土壤的腐蚀。有的时候松散的土壤全部被风刮走，留下石质化的表层; 其它 情况下细小的沙粒可能会被吹走，而正常沙粒大小的砂子不断堆积，从而形成移动的沙丘或者沙脊。

即便是在保留了土壤表层的区域，植被减少也已成为土壤大量吸取地下水的能力下降的典型因素。雨水对松散土壤的冲击会把细小的粘土颗粒冲到土壤空隙中，封闭了土壤并降低土地表层水的渗透率。地表对水的吸收急剧减少，大量水资源流失，因此土壤的腐蚀率也随即增加。地表吸收水分的能力进一步弱化使得土壤越发干燥，导致植被的进一步流失，于是便形成了土壤沙漠化的恶性循环。

在一些地方，沙漠面积的扩大很大程度上归因于干燥的气候条件。在过去的几千年里，不断增加的温室效应使得一些地方干旱问题愈发严重。倘若空气污染带来的温室效应继续恶化，沙漠化进程会在未来数十年内加速实现。

然而，可以肯定的是，大部分地区沙漠化主要都是由于人类活动造成，而非自然条件导致。沙漠边缘的半干旱土地所处的生态平衡环境非常脆弱，环境压力持续增加，而这些半干旱区域适应环境压力的能力极其有限。人口数量的增加使得人们不断向土地施压，依其提供食物和燃料。在湿润的季节里，土地兴许能够应付这些压力。但是在干旱的季节里，在沙漠周边的土地上，存在着这样一个十分普遍的现象：人类对土地施加的压力远远超过了土地自身减压的能力，因此最终形成了沙漠。

导致沙漠化的主要因素有四个：过度 种植 ，过度放牧，过分砍伐，过度灌溉。由于人口密度增加，人们对粮食作物的种植已经扩展到日益干燥的区域进行。这些区域很有可能经常会发生干旱，所以农作物种植失败是很正常的事情。大多数农作物的种植需要事先移除天然植被，而农作物欠收后又会留下大面积荒地，非常容易被风力和雨水侵蚀。

在半干旱地区，草坪是主要的天然植被，家畜 饲养 是当地的一项主要经济活动。在一个地区过量饲养家畜会导致植被覆盖面积减少，土地被大量践踏和碾碎。通常，随之而来的就是土地硬化和加速侵蚀。

在很多国家木材是用来做饭和加热的最主要燃料。人口增加带来的压力促使人们大量砍伐木材，导致许多城市和乡村周围大面积树木和灌木减少。同时人们大量使用烘干的动物排泄物作为替代燃料同样对土壤不利，因为这些珍贵的土壤成分调节剂和植物营养资源将不会再回归至土壤当中。

造成土地沙漠化的最后一个主要人为因素在于人类过度灌溉导致土壤的盐碱化。灌溉多余的水渗透到地下水位。假如没有排水系统的存在，那么地下水位上升，把溶解的盐分带到土壤表面。水分蒸发后，盐分留在了表面，形成白色的地壳层，这一地壳层阻止了空气和水接触地底下的土壤。

沙漠化问题异常严重，这是因为有佷广阔的地区和数量庞大的人群都受到了沙漠化的影响，而且要想逆转沙漠化的进程甚至减缓沙漠化的速度都面临着巨大的困难。一旦土壤被侵蚀，需要再经过几百到上千年的时间才会产生新的土壤。那些大量土壤仍保存完好的地方，亟需一个严谨而有力的保护政策和植被覆盖计划来保护现有土地。
