四级听力真题冲刺题库-1
听力真题线索内容如下（共计25题）：
题目1：During preflight, check the following: 1.Tire inflation. Too little or too much air causes tire wear and heat build-up, either of which increases the chances of a tire failure. 2.Tread wear. Most aircraft tires have 4 to 6 tread lines. These treads should be visible all the way around the tire. During preflight, roll the aircraft to assure a previous landing has not worn the tread away in one area. One flat spot on the tire, if landed on again, could cause a failure of the tire. 3. Weather checking or “dry rot”. 问1: What will it lead to if there is too little or too much air in the tire（气压太多或太少会导致什么） ? 选A （A. Tire wear 轮胎磨损.B. Tire failure.C. Tire explosion.） 问2: What is the true statement about the tread wear（关于胎面磨损的正确说法是：）? 选C （A. Aircraft usually have more than ten tread lines.B. Tires must be changed for new ones after they are worn out.C. The treads must be easy to recognize胎面纹必须易于识别。） 译文：在预飞前，请检查以下内容： 1.轮胎充气情况。气太足或太少都会导致轮胎磨损和热量积聚，这两种情况都会增加轮胎爆裂的风险。 2.胎面磨损情况。大多数飞机轮胎有4到6条胎面纹。这些胎面纹应该整个轮胎都能看到。在预飞前，要滚动飞机，以确保上一次着陆没有使某一区域的胎面纹磨损掉。如果轮胎上有一个平点，再次着陆时可能会导致轮胎爆裂； 3.检查轮胎是否出现“干裂”现象。 |
题目2：The prevention of maintenance error is a hugely complex issue, mainly because people are at the heart of it. For the successful prevention of maintenance errors, a just culture is vital to ensure that unintentional errors are not punished. Instead, the chain of events leading to the error should be investigated with the aim of determining all the contributing factors, and enabling maintenance managers to develop defenses that will stop that event chain from occurring again. In this way, we can ensure that our skillful technicians are given every assistance to enable them to deliver our flight crews with a safe and airworthy product. 问1: What is the purpose of determining all the contributing factors according to the text（根据文本，确定所有促成因素的目的是什么？）? 选B； （A. Ensure technicians are not responsible for the errors.B. Avoid errors occurring again避免错误再次发生.C. Punish the technicians concerned.） 问2: What does the author mean by "unintentional errors are not punished"（所说的“非故意错误不会受到惩罚”是什么意思？）? 选A； （A. Encourage technicians to do better（鼓励技术人员做得更好）.B. Not to be critical.C. Minor errors are not safety-threatening小错误不会对安全造成影响.） 题目译文： 维护错误的预防是一个极其复杂的问题，主要是因为人的因素至关重要。为了成功预防维护错误，建立公正的文化至关重要，以确保非故意错误不会受到惩罚。 相反，应该调查导致错误的一系列事件，目的是确定所有促成因素，并使维护经理能够制定防御措施，以防止该事件链再次发生。这样，我们可以确保我们的熟练技术人员得到一切帮助，使他们能够为我们的飞行机组人员提供安全且适航的产品。 |
题目3：关于看电视； 问1：选C （A:It has killed people's own action.它扼杀了人们自己的行为。B:People don't have enough time to watch it.人们没有足够的时间去看。C:People aren't selective sufficiently. 人们不能充分地筛选。） 问2：选A （A.Yes, he does. 是的,他有；B. No, he doesn't.不， 他没有；C. Not mentioned.没有提及。 问3：选C （A.Television is a helpful selection to the people in the woman's mind.电视对女人来说是一种有益的选择。B.All the people like to sit in front of TV.所有的人都喜欢坐在电视机前。C.A lot of people think that television is their main source of entertainment.很多人认为电视是他们主要的娱乐来源。） |
