According to the passage, an important limitation of relativity theory is that
A．it fails to describe space on a non-local level, complicating attempts to determine the geometrical model of the universe
B．it cannot account for the possibility that the universe may be multiply- connected instead of singly-connected
C．it yields inconsistencies in spatial topology equations, discriminating unnecessarily between the torus and the plane
D．it creates the illusion that observable space is curved, when in fact the universe may be Euclidean and planar
E．it does not provides sufficient variety in geometrical models to describe all the possible ways in which space may curve

Inertial guidance systems are used today in airplanes, submarines, and spacecraft. They display for the pilot his pitch, roll and yaw angles, his heading, his speed, and his latitude and longitude. These are very important items to have readily available, whether one is in a high speed vehicle with very low visibility due to poor weather, or in a spacecraft traveling in lunar orbit. The main features of inertial systems are that they are automatic and do not require any external information. Thus, the pilot does not have to feed in any information except the original position and altitude. Inertial systems serve a need on fast moving vehicles moving in a three dimensional plane, where position information is required by the pilot almost constantly.
It can be interred from the article that an inertial guidance system is similar to
A．a gyroscope.
B．a high speed vehicle.
C．a navigator.
D．a submarine.

Far from being dead, the railways are very much alive. Modern railway lines give you a smooth, untroubled journey. Where else can you eat well, sleep in comfort, feel safe and enjoy the scene while you are traveling at speed at the same time？ And we are only at the beginning. For we have just entered the age of super-fast trains, trains traveling at 150 miles an hour and more. Soon we will be wondering why we spent so much on motorways we can’t use because we have not enough money to buy the oil and planes we can’t fly in for the same reason.
1. Some people think the railways are dead for many reasons EXCEPT that ____.
A. planes and motorcars have taken the place of trains
B. oil is expensive today
C. trains are slow
D. railways lose money
2. The writers idea seems to be that ______.
A. we can do without railways
B. trains have much in common with motorcars and planes
C. motorcars and planes are not as good as trains
D. trains are as good as motorcars and planes
3. According to the writer, which of the following is NOT the advantage of railways？
A. It is cheaper to travel by train than by plane.
B. Super-fast trains travel even faster than planes.
C. The railway station is usually at the center of a city.
D. A train carries more goods than a motorcar or plane does.
4. The writer thinks that the railways, far from being dead, are very much alive because ___________.
A. we can have a smooth and untroubled journey
B. we’ll not have enough money to fly everywhere
C. we can now travel in super-fast trains
D. all of the above
5. The best title for this passage may be ________.
A. The Best Choice: Train, Motorcar or Plane
B. The Dying Railways
C. Super-fast Trains in the Future
D. Not the End, But the Beginning

When planes fall from the sky, as a Yemeni airliner did on its way to Comoros Islands in the India ocean June 30, 2009, the black box is the best bet for identifying what went wrong. So when a French submarine (潜水艇) detected the device's homing signal five days later, the discovery marked a huge step toward determining the cause of a tragedy in which 152 passengers were killed.
In 1958, Australian scientist David Warren developed a flight-memory recorder that would track basic information like altitude and direction. That was the first mode for a black box, which became a requirement on all U.S. commercial flights by 1960. Early models often failed to withstand crashes, however, so in 1965 the device was completely redesigned and moved to the rear of the plane – the area least subject to impact – from its original position in the landing wells (起落架舱). The same year, the Federal Aviation Authority required that the boxes, which were never actually black, be painted orange or yellow to aid visibility.
Modern airplanes have two black boxes: a voice recorder, which tracks pilots' conversations,and a flight-data recorder, which monitors fuel levels, engine noises and other operating functions that help investigators reconstruct the aircraft's final moments. Placed in an insulated (隔绝的) case and surrounded by a quarter-inch-thick panels of stainless steel, the boxes can withstand massive force and temperatures up to 2,000℉. When submerged, they're also able to emit signals from depths of 20,000 ft. Experts believe the boxes from Air France Flight 447, which crashed near Brazil on June 1,2009, are in water nearly that deep, but statistics say they're still likely to turn up. In the approximately 20 deep-sea crashes over the past 30 years, only one plane's black boxes were never recovered.

What does the author say about the black box？
A．It is an indispensable device on an airplane.
B．Its ability to ward off disasters is incredible.
C．It ensures the normal functioning of an airplane.
D．The idea for its design comes from a comic book.
