更多"You’re（）your time trying to persuad"的相关试题:
[填空题]You’re always forgetting your assignments. You’re a very (forget) ______ person.
[单项选择]You never see him, but they’re with you every time
you fly. They record where you are going, how fast you’re traveling and whether
everything on your airplane is functioning normally. Their ability to withstand
almost any disaster makes them seem like something out of a comic book. They’re
known as the black box.
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.
Modem 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 2000℉. When submerged, they’re
also able to emit signals from depths of 20000ft. Experts believe the boxes from
Air France Flight 447, which crashed near Brazil on June 12009, 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 ensures the normal functioning of an airplane.
B. The idea for its design comes from a comic book:
C. Its ability to ward off disasters is incredible.
D. It is an indispensable device on an airplane.

[填空题]How long should you prepare your speeches
You require ______ for each minute of speaking time.
[单项选择]If you’re in your 20s, you own your first car, your career is more or less launched, and you’re starting to look forward to owning a home. But you’re worried, too. Perhaps you’ve got some debt. You probably don’t have much in the way of savings. And with all your expenses, it doesn’t look like you’ll be able to improve that situation soon.
If you wonder how to cut comers, there’s an obvious place to look at you spending habits.
Do you buy a soda each weekend Waste $1 a day for 40 years and, when you’re set to retire, you’ll find your account is short by $190,000. Grab a calculator and you’ll discover that, over 40 years, going out to dinner twice a month at $ 40 each time amount to half a million. Even a pack-a-day cigarette habit will lighten your retirement account by $ 330, 000. And the same with cable TV and those cool earrings. They will probably amount to as much as one million.
So, the first clue to accumulating wealth is this: focus on your spending habits. Here
A. when you start your career, you are in some debt
B. when you’re in your 20s, you are in some debt
C. when you’re worried, you are in some debt
