The following appeared as part of an article in a daily newspaper: “The computerized on-board warning system that will be installed in commercial airliners will virtually solve the problem of midair plane collisions. One plane’s warning system can receive signals from another’s transponder—a radio set that signals a plane’s course—in order to determine the likelihood of a collision and recommend evasive action.” Discuss how well reasoned you find this argument. In your discussion, be sure to analyze the line of reasoning and the use of evidence in the argument. For example, you may need to consider what questionable assumptions underlie the thinking and what alternative explanations or counterexamples might weaken the conclusion. You can also discuss what sort of evidence would strengthen or refute the argument, what changes in the argument would make it, more logically sound, and what, if anything, would help you better evaluate its conclusion.

It is a terrible illustration of man s weakness to nature ,and the tsunami(海 啸) that struck the Japanese coast in March, 2011 has illustrated the difficulty of fighting against natural disasters, even for a prosperous nation.Totally preventing tsunami-damage is impossible. But there is much that can be done to minimize damage and loss of life. Measures that can be taken include designing solid buildings, and developing early-waming systems, public education programs and evacuation(疏散) strategies. Moreover, the approach of a tsunami is possibly picked up by the sensors of complicated international waming systems. Countries can use radio and television broadcasts as well as loudspeaker networks to warn the public.But an early waming system depends on how far the tsunami strikes, if it s close by, the warning system is not going to be very effective. When people are faced with an unstoppable force like a tsunami the massive waves created by events like underwater earthquakes, the best course of action for them is to get inland and to the higher ground as quickly as possible.51. The first paragraph tells us that________A.man can easily defeat the natureB.tsunamis take place only in JapanC.man’ s ability to cope with natural disasters is limitedD.the tsunami-damage in Japan is not so terribleTo prevent tsunami-damage, the following measures can be taken EXCEPT________A.designing firm buildingsB.developing early-warning systemsC.developing evacuation strategiesD.keeping the public unaware of the seriousness of tsunamisWhen a tsunami happens, the best course of action for people is to________A.listen to radio and television broadcasts for informationB.get inland and to the higer ground as quickly as possibleC.stay where they areD.rely on the warning systemsAccording to the passage , which of the folloiwing can cause a tsunami ?A.StormsB.Massive wavesC.Underwater earthquakesD.FloodsWhich of the following statements is correct according to che passage?A.The total prevention of tsunamis is possibleB.Rich countries are less affected by tsunamis than poor countriesC.Approaching tsunamis can possibly be picked up by sensorsD.An early warning system is effective when a tsunami is close by请帮忙给出每个问题的正确答案和分析，谢谢！

Passage 1
A concept car developed by Japanese company Nissan has a breathalyzer-like detection system and other instruments that could help keep drunk or over tired drivers off the road.
The car's sensors check odors inside the car and monitor a driver's sweat for traces of alcohol. An in-car computer system can issue an alert or even lock up the ignition system if the driver seems over-the-limit. The air odor sensors are fixed' firmly and deeply in the driver and passenger seats, while a detector in the gear-shift knob measures perspiration from the driver's palm.
Other carmakers have developed similar detection systems. For example, Sweden's Volvo has developed a breathalyzer attached to a car's seat belt that drivers must blow into before the engine will start.
Nissan's new concept vehicle also includes a dashboard-mounted camera that tracks a driver's alertness by monitoring their eyes. It will sound an alarm and issue a spoken warning in Japanese or English if it judges that the driver needs to pull over and rest.
The car technology is still in development, but general manager Kazuhiro Doi says the combination of different detection systems should improve the overall effectiveness of the technology."For example, if the gear-shift sensor was bypassed by a passenger using it instead of the driver, the facial recognition system would still be used," Doi says. Nissan has no specific timetable for marketing the system, but aims to use technology to cut the number of fatalities involving its vehicles to half 1995 levels by 2015.
The car's seat belt can also tighten if drowsiness is detected, while an external camera checks that the car is keeping to its lane properly. However, Doi admits that some of the technology, such as the alcohol odor sensor, should be improved. "If you drink one beer, it's going to register, so we need to study what's the appropriate level for the system to activate," he says.
In the UK, some research groups are using similar advanced techniques to understand driver behavior and the effectiveness of different road designs.
Which of the following statements is NOT true of the Japanese concept car?A. It has a sensor system that could issue a warning if the driver is drunk.
B. It has sensors that detect traces of alcohol inside the car.
C. It has sensors locked up in the ignition system.
D. It has a breathalyzer-like detection system.

In a world where it seems we already have too much to do，and too many things to think about，it seems the last thing we need is something new that we have to learn.But use cases do solve a problem with requirements:with（ ）declarative equirements it's hard to describle steps and sequences of events.Use cases，stated simply，allow description of sequences of events that，taken together，lead to a system doing something useful.As simple as this sounds，this is important.When confronted only with a pile of requiements，it's often（ ）to make sense of what the authors of the requirements really wanted the system to do.In the preceding example，use cases reduce the ambiguity of the requirements by specifying exactly when and under what conditions certain behavior occurs;as such，the sequence of the behaviors can be regarded as a requirement.Use cases are particularly well suited to capture approaches.Although this may sound simple，the fact is that（ ）equirement capture approaches，with their emphasis on declarative requirements and"shall"statements，completely fail to capture the（ ）of the system's behavior.Use cases are a simple yet powerful way to express the behavior of the system in way that all stakeholders can easily understand.But，like anything，use cases come with their own problems，and as useful as they are，they can be（请作答此空）.the result is something that is as bad，if not worse，that the original problem.Therein it's important to utilize use cases effectively without creating a greater problem than the one you started with.A.misapplied
