dump millions of pounds of carbon dioxide into the atmosphere every year. By 2050, emissions (排放)
from planes are expected to become one of the largest contributors to global warming.
That"s why researchers at MIT are designing a completely new type of airplane for NASA that will
enable greener airplanes to take flight before 2050.
The 180-passenger D"double bubble" series was designed to replace the Boeing 737 class aircraft, the
most popular jetliner in the world right now. The design is called a "double bubble" because it uses two
partial cylinders (气缸) placed side by side. Those two cylinders create a wider structure that looks like two
soap bubbles joined together.
In today"s commercial airplanes, air flows directly into the engines located on the plane"s wings. That
high-speed air flow drags on the plane, and requires more fuel to overcome the design inefficiency.
MIT"s design changes all that. By moving the engines to the plane"s tail, they take in slower moving air
present in the wake of the fuselage (机舱). Less drag means less fuel is needed to get the plane the same
distance.
Burning less fuel can help passengers" wallet as well as the environment. The environmental implications
of saving energy are as just as clear: the fewer emissions that planes spout into the atmosphere, the healthier
our planet.
But for passengers, we still have a couple decades to wait before any of these planes make it onto the
runway. NASA"s goal is to make sure the planes that MIT has designed can take off by 2035.
B. it will hold more passengers
C. it is designed to save fuel
D. it needs no runways to take off
B. Airplanes are very noisy for the environment
C. MIT"s new design will save passengers" money
D. It"s expected that NASA"s goal will be realize by the year 2035.
B. Researchers are designing greener aircraft
C. Passengers will enjoy lower prices
D. Airlines attract passengers with new planes
B. Science fiction
C. Travel diary
D. Business magazine

the hotels are full of holiday-makers and other tourists.
Last August there was a fire at the Seabreeze Hotel in Beldon. The next day, this news appeared on page
two of the town"s newspaper. The Beldon Post:
FIRE AT SEABREEZE
Late last night firemen hurried to the Seabreeze Hotel and quickly put out a small fire in a bedroom. The
hotel manager said that a cigarette started the fire. We say again to all our visitors: "Please don"t smoke
cigarettes in bed." This was Beldon"s first hotel fire for five years.
The Canfield Times gave the news in these words on page one:
ANOTHER BELDON HOTEL CATCHES FIRE
Last night Beldon firemen arrived just too late to save clothing, bedclothes and some furniture at the
Seabreeze Hotel. An angry holiday-maker said, "An electric lamp probably started the fire. The bedroom lamps
are very old at some of these hotels. When I put my bedside light on, I heard a funny noise from the lamp." We
are glad to tell our readers that this sort of adventure does not happen in Canfield.
What are the facts, then? It is never easy to find out the exact truth about an accident. There was a fire at
the Seabreeze Hotel last August: that is one fact. Do we know anything else? Yes, we know that firemen went
to the hotel.
Now what do you think of the rest of the "news"?
B. A fire broke out night in Seabreeze Hotel last summer.
C. It was not easy to find out exact truth from newspapers.
D. Two newspapers gave reports on the same matter.
a. The fire broke out in a bedroom at the hotel.
b. A cigarette started the fire.
c. An old lamp started the fire.
d. The fire broke out at night.
e. There has never been a fire in Canfield.
B. a and d
C. c and e
D. a and c
B. hotels in Beldon don"t often catch fire
C. this was the second fire at the Seabreeze Hotel
D. Beldon was a good place except that hotels there are not quite safe
B. the bedroom lights made funny noise when the fire took place
C. the firemen failed to save clothing, bedclothes and other things
D. such accidents never happened in Canfield for the past 5 years
WASHINGTON(AP)-Astronomers believe they"ve found the oldest thing they"ve ever seen in the universe:
It"s a galaxy (星系) far, far away from a time long, long ago.
Hidden in a Hubble Space Telescope photo released earlier this year is a small point of light that European
astronomers now calculate is a galaxy from 13.1 billion years ago. That"s a time when the universe was very
young, just about 600 million years old. That would make it the earliest and most distant galaxy seen so far.
By now the galaxy is so ancient it probably doesn"t exist in its earlier form and has already changed into
bigger neighbors, said Matthew Lehnert of the Paris Observatory, lead author of the study published online
Wednesday in the journal Nature.
"We are looking at the universe when it was a 20th of its current age," said California Institute of
Technology astronomy professor Richard Ellis, who wasn"t part of the discovery team."In human terms,
we"re looking at a 4-year-old boy in the lifetime of an adult."
While Ellis finds the basis for the study "pretty good", there have been other claims about the age of distant
space objects that have not held up to careful examination. And some experts have questions about this one.
But even the doubters praised the study as important and interesting.
The European astronomers calculated the age after 16 hours of observations from a telescope in Chile that
looked at light signatures of cooling hydrogen gas.
Earlier this year, astronomers had made a general estimate of 600 to 800 million years after the Big Bang
(宇宙大爆炸) for the most distant unclear points of light in the Hubble photograph, which was presented at
an astronomy meeting back in January.
In the new study, researchers focused on a single galaxy in their analysis of hydrogen"s light signature,
further finding out the age. Garth Illingworth of the University of California, Santa Cruz, who was the
scientist behind the Hubble image, said it provided confirmation for the age using a different method,
something he called amazing "for such faint objects".
B. the galaxy is believed to be the same as it was just born
C. the newly-discovered galaxy is the oldest one in the universe
D. the galaxy had traveled about 600 millions before the scientists found it
B. the life-time of the universe is surprisingly long
C. the humans have been so able as to see far into the universe
D. what we can see about the universe now is just the tip of the iceberg
B. The truth of the discovery
C. The actual age of the new galaxy
D. The size of the new galaxy
astronauts on board to attempt the country"s first-ever space walk.
The spaceship Shenzhou-7 blasted off on a Long March II-F carrier rocket from the JiuQuan Satellite
Launch Center in the northwestern Gansu Province at 9:10 pm. after a breathtaking countdown to another
milestone on China"s space journey. Onboard pilots Zhai Zhigang, Liu Boming and Jing Haipeng are expected
to orbit the earth for three days, when one of them will float out of the cabin about 343 kilometers above the
earth.
When they make it, China will become the third country in the world who is able to conduct
extra-vehicular activity (EVA) in space following the former Soviet Union and the United States.
President Hu Jintao watched the historic moment at the launch center, joined by Chinese experts and other
work staff.
Two taikonauts would enter the orbital module, where one would put on domestically-made spacesuit
Feitian and leave the module to take back test samples loaded outside, said Zhou Jianping, chief designer of
the country"s manned space project.
The other would wear a Russian Orlan suit and stay in the depressurized cabin for support, said Zhou.
"We wish we could fly freely in space just like Feitian on the ancient Buddhist murals, so we gave this name
to the homemade spacesuit," said Zhou. Feitian, which literally means flying in the sky, is the name of a
legendary Buddhist goddess.
Other tasks of the Shenzhou-7 crew include the release of a small monitoring satellite and a trial of the
data relay of the satellite Tianlian-I.
The taikonauts, all 42 years old, are scheduled to land in the central region of north China"s Inner Mongolia
Autonomous Region in a re-entry module after their mission is completed.
B. the action of counting seconds backwards to zero
C. the period of time just before something important happens
D. something that can be counted
B. Feitian is the name of a legendary Buddhist goddess
C. The spacesuit is made in Russia
D. They wish they could fly freely in space just like Feitian
B. conduct extra-vehicular activity in space
C. release a small monitoring satellite
D. take back test samples loaded outside
B. The three pilots are expected to orbit the earth for 3 days
C. The former Soviet Union and the United States can not conduct extra- vehicular activity in space
D. Two taikonauts would leave the module to take back test samples

Why did the chicken cross the road? To get to the other side.
Most people know this joke. But recently, some people have been much more worried about how the
grizzly bear and mountain lion can cross the road.
"Millions of animals die each year on U.S. roads," the Federal Highway Administration reports. In fact,
only about 80 ocelots, an endangered wild cat, exist in the U.S. today. The main reason? Roadkill.
"Ecopassages" may help animals cross the road without being hit by cars. They are paths both over and
under roads. "These ecopassages can be extremely useful, so that wildlife can avoid road accidents," said
Jodi Hilty of the Wildlife Protection Society.
But do animals actually use the ecopassages? The answer is yes. Paul Beier of Northern Arizona
University found foot marks left by mountain lions on an ecopassage that went under a highway. This showed
that the lions used the passage.
Builders of ecopassages try to make them look like a natural part of an area by planting trees on and around
them. Animals seem to be catching on. Animals as different as salamanders and grizzly bears are using the
bridges and underpasses.
The next time you visit a park or drive through an area with a lot of wildlife, look around. You might see an
animals overpass!
B. the driving conditions have improved greatly
C. the measure for protecting wildlife fails to work
D. an increasing number of animals are killed in road accidents animals on ecopassages
B. a fence built for the safety of the area
C. a bridge for animals to get over a river
D. a pass for animals to cross the road
B. animals begin to learn to use ecopassages
C. animals are crossing the road in groups
D. animals are increasing in number
B. wild animals may jam the road
C. they may see wild animals in the park
D. they may see wild
