namecomes from a Latin word meaning “large sea animal”. There are at least seventy-five kinds
of cetaceans. Scientists divide the various kinds into two major groups - baleen whales, which do
not have teeth, and toothed whales, which have teeth.
Whales have the same basic shape as fish, but they differ from fish in many ways. The most
noticeable difference is the tail. Fish have vertical (垂直的) tail fins(鳍), but whales have horizontal
tail fins. Fish breathe by means of gills (腮), while whales have lungs (肺) and must come to the
surface to breathe. But they can hold their breath for long periods.
Like other mammals, whales give birth to live young and feed them with milk produced by the
mother’s body. Most fish, however, lay eggs and do not feed their young. Whales are also
warm-blooded - that is, their body temperature remains about the same all the time. Almost all fish
are cold-blooded. Their body temperature changes with changes in the temperature of the water.
Whales have a highly developed brain and they are highly advanced life forms. They sing to their
young, engage in complex family relationships, and their communication skills are fine.
In December 2005, a whale, after being rescued from fishing nets, didn’t just swim back to deep
water. It hung around and touched each of the divers with its mouth. “Knowing that it was free, it
stopped about a foot away from me, pushed me around a little bit and had some fun,” said dive
master James Moskito. He thought it was “one of the most fantastic moments” of his life.
B. Cetaceans are not a type of mammal.
C. Whales belong to the cetacean family.

C. Whales feed their young with milk.
D. A whale’s body temperature nearly doesn’t change.

of pipes, sheds , and humming machinery - a plant in Texas to make sea water suitable to drink.
The plant is an experimental project built as the former of the state’s $150 million, full-scale
sea water desalination （脱盐）plant planned for construction in 2010.
Desalting sea water is expensive, mostly because of the energy required. The cost runs at
about $650 per acre-foot, but it only costs $200 to purify（净化） the same amount of fresh
water.
However, it is a growing field around the world as drinkable water becomes less and less in
the earth.
About two-thirds of the world’s desalinated water is produced in Saudi Arabia, Kuwait, and
North Africa. Perth, Australia, is looking to meet a third of its fresh water demand by removing
salt from sea water.
In March, Israel showed off its plant at the Mediterranean port of Ashkelon that can process
87 million gallons of fresh water a day. Singapore opened a sea water desalination plant in 2005
hoping it will meet at least 10 percent of its water needs. Two months ago, General Electric Co.
announced a $220 million contract to build a plant in South Africa.
Global output is still relatively minute - less than 0.1 percent of all drinking water. But according
to a recent report by Global Water Intelligence, the worldwide desalination industry is expected to
grow 140 percent over the next ten years, with $25 billion in investment by 2010, or $56 billion
by 2015.
B. Singapore is the only country that has put desalinating sea water into practice.
C. Purifying fresh water is much cheaper than desalinating sea water.
D. Desalinating sea water should be controlled by the government.
2. What is the passage mainly about?
B. How sea water is turned into fresh water.
C. The present and future of desalting sea water.
D. The world is in great need of fresh water.
B. close
C. real
D. tiny
B. optimistic
C. satisfied
D. worried
of its case for years. Were all those lessons a waste of your parents" money because you didn"t become a
violinist?
Even though it has been a long time since you played the violin, a new study shows that as little as one
year of music training can have a positive impact (影响) on your brain that will last the rest of your life.
In an experiment, researchers compared children who had taken music lessons to those who hadn"t.
Laurel Trainor, who studies music and the mind, discovered that the musically-trained children had better
brain responses in certain sound recognition exams. Trainor"s findings show the possibility that musical
education can actually improve the brain"s hearing cortex(大脑皮层). "The study"s results show that
music training affects attention and memory, and helps children develop learning skills. In this way music
training might lead to better learning across a number of fields," Trainor said in a statement. The effects
of music education are even more obvious on children with difficulty in reading and writing and other
language-related disabilities.
So, whether you can play a good piece of music or not, it"s likely that your years of music lessons
have prepared your brain for all the speeches, emails, and adult conversations that are part of your life
today. We should help make sure that children today have the same opportunities for music, and help
out by volunteering with or donating instruments to your school"s music education department.
B. do better in exams
C. recognize sounds better
D. response more quickly
B. improve children"s learning skills
C. help children focus their attention
D. provide more memorizing methods
B. The author has taken violin lessons when he was young.
C. Even a day"s music training can affect the human brain.
D. Music training can also help children with certain disabilities.
including humans in planes, according to a report made by Lund University Press. The bird can fly
non-stop for eight days, while the most impressive man-made airplane can only remain in the sky for 82
hours without a stop.
The bar-tailed godwit"s journey, from Alaska to New Zealand, covers over 6,835 miles. It completes
this trip twice a year, in autumn going to New Zealand, and in spring back to Alaska. The tireless bird
ends the trip without stopping once for food or rest. All other birds can only finish trips that are twice as
short as what the bar-tailed godwit travels.
One reason for the bar-tailed godwit"s success is that it has made the best use of its fuel, which is only 0.41 percent of its body weight over each hour of any given long flight. Hedenstrom, a professor from
Lund University, says, "This figure is extremely low compared with other birds." The bird also has a
special body shape that helps it fly easily. It stores body fat and protein to manage its trips. It also travels
fast, compared to other birds and animals.
Many questions remain about this bird record holder that never gets lost in the air. Researchers
wonder whether it has an inside compass (指南针) that helps it to know the direction. Please watch how
beautiful bar-tailed godwits look as they come in for a landing, along with other birds.

Chinese people aged between 45 and 54 consider themselves old, while 28 percent say that the thought
of getting old upsets them. 25 percent are afraid of getting old, and a third worry about life in old age.

reaching 60. About one third of those surveyed in China said they have enough savings (存款), and 46
percent are insured (参加保险). Around 60 percent of the Chinese participants hope they will be taken
care of by family members.
According to the survey, the French hold the most positive attitude towards getting old, with 32

compared with 3 percent globally. Indians are not bothered by old age, as 70 percent said that they don"t
