1.

Reading：美国的死谷（Death Valley）里300kg 的大石头会动，有人试着解释：

1. 风吹动的，因为存在关于山谷里有大风的纪录，而且下雨的时候，泥泞的地面变得很平，适合让风吹动石头；

2. 地下水晚上结冰，石头就能动了；

3. 人类恶搞的，比如麦田怪圈就是。

Listening：反对阅读的说法，理由分别是：

1. 没有风强到能吹动石头，并且给了张照片，石头陷在泥地里，按作者的理论，石头不应该陷下去的；

2. 是沙漠，水根本不够，且温度太高，就算晚上结冰，白天就化了，没法搬动石头；

3. 如果是人干的，那一定会留下痕迹，这种泥地里没有人能做到不留痕迹。而现场既没有人的痕迹，也没有马的痕迹。

范文：

Thelecture and the reading both talk about moving stones in Death Valley. However,what the speaker states is quite different from the main point in the reading.

Firstly,in the reading, the author considers that stones are moved by wind. Incontrast, the professor maintains the opinion that such strong wind that canmove stones does not exist. Moreover, a photo shows that stones are entrappedin muddy area, which refutes the idea in the reading that muddy area is smooth.

Second,the reading asserts that stones can move because of the freezing water. On thecontrary, the lecturer does not agree with such idea by pointing out that DeathValley is a desert, which means insufficient water. That is, the temperature indesert is so high that even if water can freeze at night, it will finally meltat daytime. Therefore, the professor considers that the freezing water theoryis also suspicious.

Third,another theory in the reading refers to human, but the professor holds anopposite view that if the moving stones are artificial, there must be traces.What’s more, no one can clear all clues in muddy place. It is also true thatthere are neither traces left by human nor those from horses. This directlycontradicts what the reading suggests.

2.

Reading: 某个地方的洞穴Erdstall可能有三种用途

1. 储存牲口或粮食；

2. 当住所，躲避强盗的攻击；

3. 宗教用途：灵魂等候区（为死去的人提供场所，让他们等待超生）。

Listening: 驳斥

1. 洞会漏雨水，储存食物不方便。在冬天Erdstall都被淹没了，而且也没发现里面有谷类残留；

2.Erdstall 太小了，只能勉强装下一家人。而且存氧气很少，只够一个人的量。另外，只有一个入口，不太可能像为了逃跑设计的；

3. 宗教用途：如果是的话，应该所有有共同宗教信仰的村子都有，但是有的村子有，有的村子没有。

范文：

Thereading and the listening both discuss the three functions of cave Erdstall.However, what the reading suggests is quite different from the main pointstated in the listening.

First,in the reading, it is said that the cave Erdstall is used for good storage. Onthe contrary, the professor disagrees with this idea and then says that thecave leaked, so it is inconvenient to store food. Especially in winter, thecave was nearly overwhelmed. Moreover, no remains of grains could be found inthe cave. This directly contradicts what the reading indicates.

Second,the author asserts that people could use the cave Erdstall to be a shelter,avoiding robbers’ attack. In contrast, the speaker holds an opposite opinionthat the cave Erdstall is too small to hold more than one person. In addition,the oxygen in the cave is ample for only one person as well. Moreover, oneentry in the cave means that the cave was not used to escape or avoid assaults.This is another part where the listening contravenes the reading.

Third,the passage indicates that religious reincarnation for soul was executed in thecave Erdstall. Nevertheless, the lecturer refutes such view by pointing outthat if the cave was treated as a ritual place, the Erdstall should have beenfound in every village across the whole region which shares the same religion.In fact, the Erdstall is only present in some, not all, of the villages. Thus,the religion hypothesis is also unconvincing.

3.

应不应该在海里建人工珊瑚礁（artificialreef）

Reading: 1. 人工珊瑚礁给鱼类更多聚集和繁殖的空间，鱼类数量可以得到增加；

2. 人工珊瑚礁可以改进小渔民的竞争力；

3. 人工珊瑚礁可以用于回收无用的材料。

Listening: 1. 鱼的总数不一定增加，这是因为珊瑚礁吸引鱼，所有鱼都跑到珊瑚礁那里去了，因此鱼的总数就减少了；

2. 不应该让私人搞小珊瑚礁，不然有安全问题：其他渔夫不知道的，下网以后就会出现问题。在浅水域，小船还会整个裂掉（cracks）。

3. 会引起环境问题，被风吹了会散开，然后把很多海洋植物和动物都搞死了。

范文：

Thelecture opposes the view mentioned in the reading with strong supportingevidences presented, aiming to further illustrate that it is not a wise idea tobuild up artificial reef in the sea.

Firstly,from the perspective of habitat, the professor states his doubt, becauseaccording to the lecture, although the fish will be attracted by the coral reefand congregate around the habitat, competition for habitat and food sourceswill be fiercer than before. And this is harmful for the population growth.

Moreover,judging from the potential economic value, the professor holds a differentview, the professor holds a different view, as the lecture further illustratesthat there will be problems concerning safety. For example, the reef will makethe sea even shallower, and if unfortunately some ship crosses over this area,the ship will crack.

Lastbut not least, on the point of natural resource, the professor never fails toexpress his concern, because in terms of the listening, there might be someenvironmental problems. When the dead reef is blown over the sea, it will bringdanger to many marine plants as well as animals.

4.

Reading：对石油和核能而言，太阳能是更好的一种选择

1. 无污染；

2. 太阳能资源非常丰富；

3. 在偏远的地方也能行得通。

Listening：不赞成

1. 占据很多空间，需要25%的城市空间来供整座城市用电；

2. 要储存太阳能，人们必须使用电池，而用来制造电池的材料非常稀少，如铅；

3. 如果位于偏远地区，维修就不便利，而且维修太阳能也需要高科技。

范文：

Thelecture opposes the view mentioned in the reading with strong supportingevidences presented, aiming to further illustrate that solar energy is not abetter alternation for oil and nuclear energy.

Firstly,from the perspective of population, the professor states his doubt, becauseaccording to the lecture, although solar energy is clean and safe, it takes upalmost 25% of the city area to set up unnecessary equipment, in order tosupport the energy use of the whole city.

Moreover,judging from the source of the energy, the professor holds a different view, asthe lecture further illustrates that in order to store the energy, people mustuse battery. The material to make battery is rare, such as lead, regardless ofthe adequacy of raw materials in obtaining the energy.

Lastbut not least, on the point of the location of the manufacturer, the professornever fails to express his concern, because in terms of the listening, basestations, which are located in the remote areas, require regular repair tosustain the normal function. And it is not convenient, especially whenconsidering the high requirement of technology.
