单选题 A new kind of radar has been developed for spaceship travelers. A working laboratory model of a new system of radar that makes use of a beam of light is said to be ten thousand times more accurate than the best comparable system of radar that used microwaves. The model has shown that this radar system, known as laser-doppler radar, can measure with absolute precision speeds varying from spaceship orbital injection (进入) velocities (速度) of five miles per second down to virtual stops—speeds of less than one ten thousandth of an inch per second. According to the scientists who are developing this system, such fine measures of velocity are of prime importance in space missions. In a rendezvous (对接) between two spaceships, or in a landing approach by a vehicle onto an orbiting space station, a bump could rip open a ship's skin, or a nudge could knock the station out of its orbit. The light-beam radar, which operates at a frequency of trillions (百万兆) of cycles per second, could easily detect and measure the movement of a vehicle edging up to a satellite space station. A control system using so precise a signal as this would allow a huge vehicle to dock at a space station as lightly as a feather.

单选题 ______, the issue doesn't seem to be difficult at all.

单选题 George Mason must rank with John Adams and James Madison as one of the three Founding Fathers who left their personal imprint (印记) on the fundamental law of the United States. He was the principal author of the Virginia Declaration of Rights, which, because of its early formation, greatly influenced other state constitutions framed during the Revolution and, through them, the Federal Bill of Rights of 1791. Yet Mason was essentially a private person with very little inclination for public office or the ordinary operation of politics beyond the country level. His appearances in the Virginia colonial and state legislatures were relatively brief, and not until 1787 did he consent to represent his state at a continental or national congress or convention. Politics was never more than a means for Masson. He was at all times a man of public spirit, hut politics was never a way of life, never for long his central concern. It took a revolution to pry him away from home and family at Gunston Hall, mobilize his skill and energy for constitutional constrnction, and transform him, in one brief moment of brilliant leadership, into a statesman whose work would endure to influence the lives and fortunes of those 'millions yet unborn' of whom he and his generation of Americans spoke so frequently and thought so constantly.

I spent the whole day there, buying lots of little gifts and handmade souvenirs for my friends back home. Cindy: 58 . I'll make sure I take my wallet. Tony: Of course. And we visited the Pyramids and the Sphinx yesterday. 59 —like a living history lesson. I even rode a camel. Cindy: Is there anything you haven't done? Tony: Well, I'm going to take a boat trip down the Nile tomorrow to finish my holiday in style! And, if I get time, 60 . Cindy: Goodness me! You're going to need another holiday!

单选题 Devon, 17, is used to paying her own cell phone and car expenses. But lately it's been harder. The family she baby-sits for hash' t been calling as much as usual and she couldn't find a job over the summer. Devon's dad said it's a sign of the tough economy. He told her he's feeling the pinch too and that he had to use her college fund to pay the loan(贷款). This kind of money troubles isn't strange to common families these days. In fact, it's hard to avoid news about the economy on the screen of the TV or the computers recently. It can seem a bit worry and some families are hit really hard. For most people, the big problem is that things cost more at a time when they have less money to spend. But higher prices aren't the only problem. Many people are having a tough time making payments on some types of home loans. Therefore, some families are cutting back on what they spend. For example, eating out less, staying home instead of going on vacation, moving to a less expensive house and so on. However, as discouraging as things may seem now, the good news is that the economy always gets back on track after a while. Jobs may be hard to find, but the slow economy can open up new opportunities. The couple Devon babysat for might cut back on evening's out, but they could be interested in hiring her for after-school care. Perhaps it's time to sell her old toys and baby gear (设备) in the basement(地下室) or help others sell these items online if she is-good at it. She could charge them a fee to sell their old stuff(东西).
