【填空题】Lesson 5 Cloze 拓展 选择单词合适的形式填空 Automation in Air Traffic Control enhance obstacles alert environment potential in charge track（跟踪） malfunction deploy In the world of air traffic control (ATC), a series of automated solutions are 1 to provide controllers with more accurate information earlier, help increase visibility at airports, and 2 communications with pilots. Communication, navigation and surveillance tools help ATC controllers to fulfil their primary responsibility of preventing collisions between aircraft. These tools become more and more vital to safety and increased efficiency. With the number of flights handled increasing exponentially every year, the pressure is also rising for controllers. This creates a higher 3 for human error and makes the role of automated assistance even more important. Airport visibility is an area where automation systems currently provide a major boost. An ATC tower window serves as the main source of information to controllers while they give clearances to aircraft landing, taking off, or taxiing to and from the stand. Nevertheless, 4 such as hangars and stands, poor weather conditions, and runways that stretch into the horizon can make their job more difficult. Controllers therefore use radar displays to supplement their awareness. Automated warnings, such as those provided by a short-term conflict 5 system, let the controller know automatically if an aircraft or vehicle is attempting to enter a runway when it is already occupied. With automation, aircraft can be accurately 6 with reduced separation standards, thus it reduces the load on the controllers and increase airspace capacity. It offers 7 benefits as well, because it means there will be less flight delays and that aircraft will have their engines running for shorter times.”but one of the biggest problems with automation is that it can fail and it is therefore necessary for the system to make clear to operators when it has 8 and for controllers to recognize when this has happened. In addition, controllers are needed to be properly trained to use and 9 new automated systems. Could air traffic controllers be replaced by automated systems altogether one day? Both experts say that although the systems are proven to increase efficiency, for the next 20 years at least, humans will remain 10

【填空题】Proofreading & Error Correction Each indicated line contains a maximum of one error. In each case, only one word is involved. You should proofread the passage and correct it in the following way: For a wrong word, underline the wrong word and write the correct one in the blank provided at the end of the line. For the missing word, mark the position of the missing word a “^” sign and write the word you believe to be missing in the blank provided at the end of the line.

Humankind’s future safety and longevity of life on Earth largely depend on the environment which we live. Keeping the air we 1 breathe free of pollution is a major priority towards making this earth a safe place. Other areas of concern are water, land, the ozone layer, and the preservation of flora and fauna of the planet. Every country has ecological issues to deal. In South America, 2 the rain forests are rapidly disappearing as people burn and cut down trees to make for farmland. Many Middle-Eastern and Asian countries 3 have a battle to fight with air, water, and land pollution. Lakes and swamps are spread with debris. 4 Mass chemical spraying is used to kill pests on trees and plants. Abundant 5 use of water in countries as China has caused major water shortage. 6 Rivers become polluted by factories and the populations that live on their banks. Global warming is considered a major factor caused the droughts 7 in eastern China, the Sudan, Ethiopia, and northern Kenya. The reduction of the ozone layer is blamed for the global warming trends in variant countries of this globe, 8 and the spread of disease like skin cancer. Societies at large need to pay attention to the existing problems in order to get of the imminent danger of famine, 9 drought and diseases that rise from the damage that pollution causes. 10
