you"re traveling and whether everything on your airplane is functioning normally. Their ability to withstand
(承受) almost any disaster makes them seem like something out of a magic 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 (设备) 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 box was completely redesigned and moved to the back of the plane - the area least affected by 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 be discovered more easily.
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 huge force and temperatures up to
2,000℉. When in deep water, they"re also able to send 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.
B. The idea for its design comes from a magic book.
C. Its ability to avoid disasters is unbelievable.
D. It is an inseparable device on an airplane.
B. The total number of passengers on board.
C. The scene of the crash and extent of the damage.

B. To caution people to handle them with care.
C. To make them easily discovered.
D. To meet with international standards.
B. There is an urgent need for them to be reconstructed.
C. They have stopped sending signals back.
D. They were destroyed somewhere near Brazil.

parent"s particular ways on the parenting style that have become known humorously as helicopter parenting
and submarine (潜水艇) parenting. Helicopter parents hover over their children, managing every aspect of their
child"s life. On the contrary, submarine parents remain"hidden" coming to the surface when guidance is needed.
While helicopter parents may have the best intentions, in reality, they are raising children with few problem
solving skills. Children with hovering parents never get the chance to face disappointment and build up their
ability to recover from misfortune.
Think about your typical submarine. Submarines usually remain underwater. In case of a need for
emergency surfacing, submarines can rise so quickly they are driven partially out of the water. Submarine
parents also remain out of sight, yet able to pop up in the case of an emergency.
I admit I"m a submarine mom. My job as a parent is to have fun with my daughters while letting them
explore and learn natural consequences.
My older daughter found herself acting in commercials and making more than minimum wage as a teen.
To give her a sense of the real world, I insisted she spend three weeks every summer, picking strawberries
and earning $3.50 on a good day.
When my youngest daughter Sondra was six, she wanted a very expensive American Girl Doll. I cut the
full color 18" picture out of the American Girl catalogue and had it laminated (压膜)."Here"s your American
Girl Doll." I said"When you turn nine, I"ll buy you the 3D doll on your birthday." Sondra played with her flat
doll for months, making clothes and furniture for her. She learned creativity. I saved $88.00.
B. Funny experiences of a mom.
C. Humorous stories about parents.
D. Different styles of parenting.
B. fly around
C. watch over
D. set aside
B. They try to do everything for their children.
C. They teach their children how to face failures.
D. They help their children explore by themselves.
B. is always making promises
C. is strict with her daughter
D. tries her best to save money
B. using figures and giving evidence
C. analyzing data and drawing conclusions
D. making comparisons and giving examples
is when two American astronomers reported on their study of all the light in the universe. They said that the
universe would appear to the human eyes to be a light greenish color.
Karl Glazebrook and Ivan Baldry of Johns Hopkins University in Baltimore, Maryland, reported their finding
in January. They presented the research at a meeting of the American Astronomical Society. They said that
finding the color of the universe was not part of their more serious scientific research. They did it for fun.
However, earlier this month, the scientists admitted making a mistake. They said their finding was much
more colorful than it should have been. They now say the light from our universe is closer to white. It is more
like a milky or creamy white color.
Their study attempted to show what people might see if they could observe the universe from far away.
The scientists found the average color by combining light from about two-hundred-thousand star systems.
Their information came from an observatory in New South Wales, Australia. The scientists gave a number
value to the colors of the different star systems. Then they added the numbers together and found the average
measurement. The scientists used this average to identify the color of the universe. They said it was a very
pretty light green. Many newspapers and television stations reported their finding.
Other scientists and color engineers attempted to reproduce the result. Mark Fairchild of the Rochester
Institute discovered a mistake in the computer software program used by the Johns Hopkins scientists.
When the mistake was corrected, the results changed. The new color of the universe is much less colorful.
It is very close to white.
B. black
C. blue
D. light greenish
B. observing at an observatory in India
C .making long-term scientific research
D. using computer software programs
B. Ivan Baldry.
C. Mark Fairchild
D. Johns Hopkins.
B. the light from our universe is a light greenish color
C. the new color of the universe is much more colorful
D. the finding of the color of the universe is difficult
a preference-or even the result of late-night studying or instant messaging-but is rooted in their biological
rhythms(节律). All of this would be little more than an interesting observation except that most high schools
start so early, and so many teenagers are having a hard time staying awake.
A recent article in The Times cited a National Sleep Foundation survey in which more than a quarter of
the students reported that they fell asleep in class at least once a week. Researchers say this is true because
youngsters - beginning around age 12 until they reach their mid-20s-only start producing melatonin, the
sleep-inducing hormone(荷尔蒙), around 11:00 pm and that production lasts until about 7:00 am. In adults,
melatonin lasts to around 4:00 am. Trying to wake up a teenager before 7:00 am is like trying to awake an
adult before 4:00 am.
The obvious remedy(补救)would be for high schools to start later-well, after 8:00 am. A handful of
schools that have switched have reported beneficial results. School officials in Minneapolis say that
attendance improved and students" grades rose slightly after they changed to start at 8:40 am several years
ago. In Wilton, Conn., where the high school start time was pushed back to 8:20 am from 7:35 am, teachers
and parents reported better student behavior and greater alertness. Surveys of students in both districts
indicated that they did not use the later starts as an excuse to go to bed later.
Numerous districts have considered the idea of later high school hours, only to drop it because of fierce
adult opposition. Coaches complain that the later classroom hours in the afternoon would take time from
their training programs and teams" success. School bus companies would be forced to change their
schedules. And many parents complained that they would have to adjust their own schedules.
Many schools officials say more research is needed. We"re all for that and for remembering that the goal
is to educate youngsters-and for that they need to be awake.
B. they waste too much rest time sending instant messages
C. they prefer to stay in bed rather than get up early
D. their biological systems make them do so
B. adults sleepy after 4:00 am
C. youngsters sleepy before 7:00 am
D. adults awake after 4:00 am
B. later high school start time made students go to bed late
C. students don"t go to bed late even though they have later high school hours
D. later high school start time is a very effective measure
① School team coaches.
② Many parents.
③ School teachers.
④ School bus companies.
B. ①②④
C. ①③④
D. ②③④
B. negative
C. indifferent
D. unclear
to show your friends that you"re happy to see them. But what happens if your face and body send mixed
messages? Scientists have recently deal with these questions. They found that when a person is looking at your
face, he or she might not believe what he or she sees if your body language doesn"t match the feeling that your
face shows.
Studying such mixed messages is nothing new for scientists. Previously, they had found that the tone of a
person"s voice can be more important than the words that are spoken. For example, most people tend not to
believe a person who says in a flat voice,"I"m so excited."
When it came to emotions conveyed by facial expressions and body language, most scientists suspected
that the face was more important. To test if this was true, psychologists from the Netherlands and Boston
showed people a number of pictures of isolated faces and isolated bodies (with faces blurred out) that showed
anger or fear. They also showed pictures in which angry or scared faces were paired with angry or scared
bodies.
An angry face had low eyebrows and tight lips. A scared face had high eyebrows and a slightly open
mouth. An angry body had arms back and shoulders at an angle, as if ready to fight. A scared body had arms
forward and shoulders square, as if ready to defend.
Using the pictures, the researchers asked people to quickly press a button that matched the correct facial
emotion: anger or fear. When people looked only at faces, they chose the right emotion about 81 percent of
the time. But when people looked at a mismatched picture-a scared face with an angry body, for example-they
correctly guessed the emotion on the face only 64 percent of the time.
These results told the researchers that mixed signals can confuse people. Even when people pay attention
to the face, body language subtly influences which emotion they read.
So, your body language is important for telling people how you feel. And if you want to be understood, it
helps to avoid sending mixed messages.

eat bamboo will immediately jump into their mind. Scientists from Mississippi State University, however, are
interested in what the bears leave behind; their poop (排泄物). At a recent meeting in Denver, Professor Brown
at the university presented her research showing how panda poop could inspire a new way to obtain energy
from plants, which are a renewable energy source. Usually, plants can be called biomass (有机燃料) when
they are used as an energy source.
Burning biomass is one way to capture its energy, but Brown hopes panda poop can teach scientists
something about breaking down biomass. Pandas - or at least the bacteria in their stomachs - are very good at
getting energy out of bamboo. Unlike cows, which use 4 stomachs to digest large amounts of grass, a panda
has only one stomach. Bamboo comes in, and poop goes out.
Every day for 14 months, Brown and her team on this project, counted the bacteria in the poop of the two
pandas. Ya Ya and Le Le living at the Memphis Zoo. Her studies turned up 12 species of bacteria that break
down biomass, including one that had never been found in pandas. Brown says that because the poop contains
bacteria that break down biomass, it could also be used to break down other types of biomass.
Now the scientists hope to identify the chemicals that help with the process of breaking down biomass and
then figure out how the bacteria work. If those chemicals can be made in the lab, they could be used to turn
biomass - like grass or other plants - into fuel.
Brown says she doesn"t mind handling panda poop."It"s probably the most pleasant material to work with,"
she says,"My colleagues and I have been working with other poop for a long time, and we can assure you it
has a fairly pleasant smell associated with it."
B. to create a renewable energy from plants
C. to learn a lesson of energy from panda poop
D. to figure out how the bacteria work for us mankind
a. Identify the chemicals helpful to break down biomass.
b. Find the bacteria in panda poop which break down bamboo.
c. Reproduce the chemicals in the lab to turn biomass into energy.
d. Analyze how the bacteria in panda poop work in panda"s stomach.
B. a, d, c, b
C. b, d, a, c
D. b, a, d, c
B. Pandas are capable of getting energy using stomachs.
C. Scientists have learn something new from panda poop.
D. Pandas can get energy from bamboo more efficiently.
B. Challenging.
C. Inspiring.
D. Sick.
