听力填空

Hola,大家好，我是AmyLee，第一次跟大家见面，以后就由我来负责老托福听力的讲解。该材料来自于老托partb，partc，是公认实施有效的听写材料，对于上手托福时间不长的同学非常适合。我曾经一次短时间备考听力提高了7分也归功老托。今天是第一天，希望大家和我一样一定要坚持下来噢。相信坚持学习的同学听力上都会有很大的飞跃。

Nopain, no gain.我们的安排是这样的，第一遍用听力软件精听材料（建议做单句听写，听写的时候不要偷看我给的挖空题），然后按照我给的挖空题填关键词，回复后即可看到听力原文和文章精解，我将把难点和易错点one by one分析给大家。

回复填空答案格式如下：1____2____3____...et.al.

Located at the NASA Research Center in Iowa is a 5,000-_____,___ of water, and inside the _____is an underwater ______ designed by Dava Newman, an _______engineer. For four years Newman observed _______as they _______ walking on the Moon and on Mars on her underwater moving belt. ……to keep their balance and walked awkwardly. But at _______gravity, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmill, the divers took longer, graceful ______until they comfortably settled into an even quicker pace. ……to allow for freer movement, the _______ and knee areas of the space suits will also be altered.

【听力原文】

Located at the NASA Research Center in Iowa is a 5,000-gallon vat of water, and inside the tank is an underwater treadmill designed by Dava Newman, an aerospace engineer. For four years Newman observed scuba divers as they simulated walking on the Moon and on Mars on her underwater moving belt. She wanted to discover how the gravity of the Moon and of Mars would affect human movement. To do this, Newman attached weights to the divers and then lowered them into the tank and onto the treadmill. These weights were carefully adjusted so that the divers could experience underwater the gravity of the Moon and of Mars as they walked on the treadmill. Newman concluded that walking on Mars will probably be easier than walking on the Moon. The Moon has less gravity than Mars does, so at lunar gravity, the divers struggled to keep their balance and walked awkwardly. But at Martian gravity, the divers had greater traction and stability and could easily adjust to a pace of 1.5 miles per hour. As Newman gradually increased the speed of the treadmill, the divers took longer, graceful strides until they comfortably settled into an even quicker pace. Newman also noted that at Martian gravity, the divers needed less oxygen. The data Newman collected will help in the future design of Martian space suits. Compared to lunar space suits, Martian space suits will require smaller air tanks; and, to allow for freer movement, the elbow and knee areas of the space suits will also be altered.

下面我会将每个要点一一解释给大家，但是建议先不要看中文译本，因为有了英文的原文大家自然很明白每一句话的意思，不要偏信所谓的译本，因为你们就是最棒的哦！^^

首先这里面有几个特殊的地名和量词需要注意，NASA是美国航空航天局，大家要记住了，这个在航天文章里边是经常出现的特有名词。Gallon,中文是加仑，是美制的一个常用量词，Iowa是爱荷华---美国的一个州，可能这些词一上来就把大家难住了，但是稍加注意，我们就能听出来这些词虽然我们暂时不懂，但是不会影响结构性的分析，所以要沉住气继续听。
attached weights to 这个短语是把sth.附加在sth.上，放在听力里就是给潜水员负重，大家在这个点上可能会有错误噢。

so at lunar gravity，在月球引力下，后面一句是结论性的句子：潜水员很难保持平衡，行走也很费力。要注意这句话哦，这样的句子很可能在接来下的问题中问道。这句话也有不少同学听错了意思哦。
the divers took longer, graceful strides until they comfortably settled into an even quicker pace在听这一句时，我也听了好几遍，特别是the divers took longer, graceful strides和 settled into an even quicker pace，意思就不多解释了，只是以后再碰到多个形容词修饰的名词时要把握重点，重点当然是放在名次上。
Space suits 太空服，我第一遍没反应过来，不知道你听懂了吗？the elbow and knee areas of the space suits will also be altered.这个是肘部和膝部的意思，alter这个词语是 改变的意思，可以放在作文里噢，这个词很好用的！


【听力译本】

NASA的调查中心在IOWA有一个可容5000加仑水的大容器，内部有一个由航空宇宙工程师Dava Newman设计的水下踏车。四年来，Newman一直观察潜水者在她的水下传送带上的模仿在月球和火星上的行走。她想知道月球和火星的重力是如何影响人类的活动的。为了做到这些，Newman给潜水者加了一些重量，然后把他们放入水中，放到脚踏车上。这些重量是谨慎调整过的，因此。潜水者在脚踏车上时可以感受到月球或火星上的重力作用。Newman推断在火星上的行走易于在月球上的行走，月球的重力小于火星，所以在月球重力的作用下，潜水者要努力保持平衡并且走路更笨拙一些。在火星的重力作用下，潜水者有更多的牵引力和稳定性，并且可以轻松达到1.5英里/小时的步速。随着Newman逐渐给脚踏车加速，潜水者步幅更大，动作更优美，直到他们达到一个更快步速。Newman也注意到在火星重力作用下，潜水者需要的氧气更少。Newman收集到的资料将有助于未来火星空间服的设计。与月球服相比，火星服将有更小的空气罐，而且，为了保证更自由的行动，火星服的肘部与膝部的空间也会被改变。

好了，今天就这么多吧。

我也是从托福的阴霾里慢慢走出来的，深知大家的痛苦，但是我们比别人多吃了苦就意味着我们可以变得更强。
祝大家每天进步一点点！
