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.

too. They want to know about ocean water and the plant and animal life deep in the ocean.
In 1934 the scientist William Beebe dived 3,000 feet below the surface in a hollow steel ball. In 1935
August Piccard dived 10,330 feet. In 1960 his son Jean dived to a depth of 35 ,800 feet.
All these early dives were deep. But the divers could not stay down for very long. They had to come back
up to the surface after a few seconds. Scientists needed to stay down longer to study life below surface.
Gradually they succeeded. Cousteau, a Frenchman, was able to keep down to a depth of 36 feet for one month
and to a depth of 90 feet for a week.
Now scientists are developing even better equipment. With this new equipment, man can stay below the
surface for days or even weeks. In 1962 Cousteau set up a research station 35 feet below the surface. Then,
in 1964,he set up another station on the ocean floor of the Red Sea. This was the first undersea station to
operate without help from the surface.
Many countries are now studying undersea living. The former Soviet Union has an undersea laboratory in
the Crimean Sea. The United States has a laboratory 50 feet down on the ocean floor off the Virgin Islands. In
1970 five men lived there for two weeks. Then a team of five women scientists stayed in the laboratory. Next
came other teams of men. All were there to explore the ocean depths and to make plans for the use of its
resources. Scientists hope to find enough mineral, vegetable, and animal wealth there to provide food for the
entire world.
B. stay down longer to study life of the plant and animal below the surface
C. know about the plant and animal life deep in the ocean
D. both A and C
B. August Piccard.
C. Jean Piccard.
D. Cousteau.
B. An American.
C. A Russian.
D. The passage made no mention.
B. Up to now only five women scientists have stayed in the undersea laboratory.
C. The purpose of setting up the undersea laboratories is to make plans for the use
of the resources in the ocean.
D. None of the above is true.
B. that scientists try to make use of resources in the ocean
C. about the secret of the plant and animal life in the ocean
D. both A and B
China"s "Cultural Heritage Day" falls on the second Saturday of June every year. Many celebrations are held
and all cultural relic protection sites are 1 to open free to the public on the day.
There is no 2 that various celebrating 3 across the country will arise public 4 of the importance of
cultural heritage protection and 5 the young people to love the fine 6 culture of the motherland.
China faces a heavy task to protect and rescue its cultural 7 . We need to consider seriously the 8 of the
lack of awareness about cultural heritage protection. 9 , Heritage Education is one of our main approaches.
People cannot 10 value cultural heritage if they do not know 11 it is important or how to protect it. Over
the past several years, CHP 12 over a hundred educational 13 to various groups, such as schools,
government offices, 14 the general public. Many people have attended CHP seminars. Typically, each seminar
lasts two or three hours and 15 of an informative presentation, 16 by a longer question-and-answer session
and discussion. Each attender with 17 knowledge of cultural heritage, 18 it to be just the Forbidden City
(紫禁城) and the Great Wall. People often think that the duty only 19 to the government. So "Cultural Heritage Day" will be a welcome 20 to educate a wide public on world heritage conservation.

| If the sun has enough power to warm and light the whole earth, it must have enough power to do other things, too. Can we use the sun"s abundant energy to supply electricity,or at least to perform the functions which electricity or other types of power usually perform? The answer is yes. For example, people have been using the reflected heat of the sun to cook for many years. Solar cookers have been built with several curved mirrors reflecting the sun and focusing its heat on the cooking component. This equipment can be used just like a gas or electric stove: it is more expensive to make but it does not need any fuel. So costs nothing to use. Another possibility of using solar energy is in house heating. The form of energy we use most is electricity, and every day more is needed. But electricity has to be made, too, and to make it, are required-oil, gas and nowadays even uranium(铀). The question which worries everyone today is: how long will these fuels last? Nobody knows it for sure, but most experts think it will soon be difficult to obtain sufficient electricity from these sources. It is possible that the sun can make a contribution here, too. Solar power has already been used to produce terrific heat. In Southern France a solar furnace( huge stove) has been built, where temperatures reach more than 3,000 ℃. This furnace is only used for experiments at present, but could be used to produce steam for a power station. | ||||||||||||||

| Computer hackers (黑客) have now got their hands on mobile phones. A phone virus (病毒) can 1 your phone do things you have no control over, computer security (安全) experts 2 . It might 3 the White House or the police, or forward your personal address book to a marketing company. Or it could simply eat into the phone"s operating software, turning it 4 and erasing your personal information. Similar viruses have already made mobile phone owners 5 . in Japan and Europe. Ari Hypponen, chief technical officer of a computer security in Finland, said a virus can get your 6 and send them elsewhere. And it can record your 7 . Mobiles are now able to surf the Net, send emails and 8 software, so they are an easy 9 for the same hackers who have sent viruses to computers over the last decade.

In Japan, if you opened a certain email message 14 your mobile, It would cause the phone to repeatedly 15 the national emergency number. So phone operators had to 16 emergency calls until the bug was 17 . In Europe, mobile"s short message service, 18 SMS, has been used to send codes that could damage phones.
