They must be ready for immediate use when fire breaks out. Most portable (手提式的) kinds operate
for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and
planes to carry extinguishers.
Since fuel, oxygen (氧气) and heat must be present in order for fire to exist, one or more of these
things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material
below a certain temperature, the fire goes out. The cooling method is the most common way to put out
a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering
the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from
a fire, so that it can find no fuel.
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in
three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help
keep the fire on. Such fires can be stopped most readily by cooling with water.
B. Water
C. A blanket.
D. An extinguisher.
B. reducing the heat
C. removing the fuel
D. cutting off the oxygen
B. how it comes about
C. what kind it is
D. where it takes place
B. Another type of extinguishers
C. How fires break out.
D. How fires can be prevented.

wonder appears to be strange: The fatter the bird, tile better it flies.
The results of their study led to a theory opposite to a central one of aerodynamics (空气动力学),
which says that the power needed to fly increases with weight.
For birds, obviously, the cost of flying with heavy fat is much smaller than we used to think.
Researchers found that red knot wading birds double their normal body weight of 100 grams before
making their twice-a-year nonstop flight between the British Isles and the Russian Arctic. Distance:
5,000 kilometers.
Another study in the magazine Nature measured the advantage of flying in an aerodynamic group
which allows birds to save energy by flying smoothly and quietly in the lead bird" s air stream.
Flying in groups, their heart rates were 14.5 percent lower than flying alone, according to Henri,
a French scientist. The findings help explain how birds complete difficult migrations. Researchers had
thought that thinner, stronger birds would have the best chance to survive.
The first study suggests that building up fat to be burnt as fuel during the migration is worth more
than the energy it takes to carry the additional weight.
In the study, researchers said their team studied the birds flown at different body weights during
28 simulated (模拟的) flights. They forced a small amount of special water into the birds" bodies so
that they could measure the amount of energy burnt during the flight.
B. 100 grams
C. 150 grams
D. 200 grams
B. alone
C. in groups
D. in pairs
B. weaker
C. thinner
D. fatter
B. Birds Fatten Up For Journey
C. How Birds Build Up Fat For Journey
D. How Birds Burn Energy For Journey
are very different from the sort of teaching most often used in schools and colleges.
In seminars you will be taught with discussion focusing on a text or topic set in advance in a friendly
and informal atmosphere. The purpose is to provide an opportunity to try out new ideas and to think
through difficulties with fellow- learners. Students develop friendships through groups, as well as learning
more about other people"s ideas. You can also know your tutors as an individual rather than a face at the
end of the room.
Lectures are the most formal. There may be over a hundred in the audience and the lecture Mil last about
fifty minutes. The value of the lecture is that it can present to a large number of people information which
is not readily available in books, that it can give you an opportunity to hear a specialist develop a coherent
(有条理的) argument, and that it can show visual material to a wide audience.
Your typical week"s work will feel strange after school or college since there are fewer timetabled
teaching hours. Each week in the first year you may attend about six lectures and four to six seminars or
tutorials (辅导). For the rest of the time you are working on your own, doing the necessary reading in
preparation for tutorials or writing seminar papers. When writing an essay or carrying out project work,
you can often discuss with your tutor about the title and topic.
B. to persuade you to try out new ideas
C. to stress the importance of discussion
D. to make you believe that seminar is more helpful
B. to learn more about other people"s ideas
C. to offer a chance to discuss with a specialist
D. to present to students information not found in books
B. you may give lectures and seminars
C. you may have fewer timetabled teaching hours
D. you may write seminar papers with fellow-learners
B. lecture is better than seminar
C. seminar is more formal than lecture
D. lecture is more formal than seminar
(环保局), there is no way to stop all flooding--sooner or later nature will produce something that will
beat even the strongest defences.
Warning people of tiffs danger is very important if we are to prevent the great loss of life seen
fifty-three years ago. Indeed if the Flood Waming System that currently exists had been around on that
cold, stormy night in January 1953, many lives would have been spared.
The Environment Agency took over the role of flood warning in 1995 from the police who had to go
door to door or sound alarms to get the news out. The service is being constantly improved and a
combination of better technology and increased investment following the Easter Floods of 1998 has led to
the creation of Floodline and an automatic (自动) messaging system that can warn thousands of people in
very little time.
Floodline 0845 988 1188 offers information and advice 24 hours a day and if warnings are in place,
callers can get information either from local updates or by using a quick dial code for their area.
The Flood Warning team in Kent has also sent letters to the people living close to the rivers or the sea
and invited them to join the AVM (automated voice messaging) system. Anyone choosing to take up this
free service will receive a recorded message directly to their home, business or pager telling them of tile
level of warning, giving them as much time as possible to carry out their flood plan and save items that
cannot be replaced if lost or damaged, such as photographs or children"s favorite toys.
a. Many people lost their lives in the flood in 1953.
b. The Flood Warning system was already in use in 1953.
e. Flood defences can stop all flooding.
d. The Environment Agency began to warn people of flood ill 1995.
e. Floodline was created after the Easter Floods of 1998.
B. b, c, d
C. a, c, e
D. a, d, e
B. A piece of equipment designed to receive and show messages.
C. A page of papers written to offer messages.
D. A person, invited to write pages of messages.
B. Floodline 0845 988 1188
C. the Flood Warning team in Kent
D. automated voice messaging system
B. Technology In Flood Defences
C. Flood Warning System
D. Easter Floods
watch dinosaurs in order to know how they lived and whether they were good parents Instead, they
have to search hard for information from dinosaurs’fossils（恐龙化石）because dinosaurs died out
millions of years ago.
It’s very difficult for the scientists to reach an agreement because different results can be got from
the same fossils, Many fossils of the same kind of dinosaurs have been dug out from one place. They
might have formed when an entire group of dinosaurs got stuct（陷入）all st once. Or they might have
been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thys we
can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.
Though there are two different results, dinosaur scientists now generally agree that at least some kinds
of dinosaurs lived in big groups. “That’s pretty much settled at this point.” Says Paul Sereno, A kind of
dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and
south,suggesting that they even moved long distances together.
As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living
relativers of dinosaurs―birds and crocodiles―for possible models. Birds give a lot of care to their young,
while crocoeiles just help their young to the water, The discovered fossils of dinosaurs sitting on their gees
and staying with their young suggest the parents were taking care of their babies, but we still cannot say
that all dinosaurs did the same.
There is still a long way to go before the above questions could be answered. Dinosaur scientists will
have to find more proof to reach an agreement.
B. examining modern animals
C. watching dinosaurs
D. using teleeopes
B. Most dinosaurs moved long distances.
C. Many dinosaurs settled in the north.
D. Some dinosaurs lived in big groups.
B. studying dinosaurs’living relatives
C. following the tracks left behind
D. working on dug-out dinosaur eggs
B. Baby crocodiles can look after themselves well.
C. Some dinosaurs took care of their young.
D. Birds and crocodiles take good care of their young.
because it is very rewarding and varied. They work not only inside a laboratory, but also out in the field.
Fieldwork includes traveling to river? oceans and lakes in order to collect information and specimens (~2~),
reading, writing and speaking me also very important to the job, fish scientists need to read the research of
other scientists. They must he able to write up their own research clearly so that others can follow it. They
also need to be able to give lectures about their findings, so that they can spread knowledge.
Ichthyologists who wish to specialize can choose any one of three areas of study. The first area is
aquaculture (水产养殖). This involves the study and practice of fish farming and management. Because it is
a rather new study, there are very few job opportunities available. However, as there is so much to discover,
many see it as an exciting area for a new ichthyologist to enter. The second area is fisheries science, which
means working with a team of scientists to find out more about different fish species. The third area is about
the protection of natural fish populations. This is very important today, given that many fish species are in
danger of dying out because of the actions of humans.
To become a successful fish scientist, you need to have a curious mind and be able to work on your own.
You also need to be able to handle equipment and perform experiments; but most importantly, you must love
fish. To become an ichthyologist, you will need to train at a university to pass a Bachelor of Science degree.
For this, you will need to be good at mathematics, physical science and biology. Then, you will need to study
for another year to complete an honours degree in ichthyology. This honours degree contains coursework
about all aspects of fish. You also need to complete a research paper.
B. They have to study science and mathematics.
C. They work in fields as well as in laboratories.
D. They read research papers written by others.
B. Aquaculture is the study of fish protection.
C. The life of an ichthyologist can involve lots of travel.
D. A fish scientist needs to be independent and curious about things.
B. Jack, because he likes to travel and read adventure books.
C. Jenny, because she likes science, mathematics and reading about dinosaurs.
D. Jane, because she likes mathematics, science, biology and searching rock-pools.
B. science researchers
C. fisheries experts
D. fish farmers
