Do you find getting up in the morning so difficult that it"s painful? This might be called laziness, but
Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labour through your work you may say that you"re "hot". That"s true.
The time of day when you feel most energetic is when your cycle of body temperature is at its peak.
For some people the peak comes during the forenoon. For others it comes in the afternoon or evening.
No one has discovered why this is so, but it leads to such familiar monologues (自言自语) as: "Get up,
John! You"ll be late for work again!" The possible explanation to the trouble is that John is at his
temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives
realize what these energy cycles mean, and which cycle each member of the family has.
You can"t change your energy cycle, but you can learn to make your life fit it better. Habit can help,
Dr. Kleitman believes. Maybe you"re sleepy in the evening but feel you must stay up late anyway.
Counteract (对抗) your cycle to some extent by habitually staying up later than you want to. If your
energy is low in the morning but you have an important job to do early in the day, rise before your usual
hour. This won"t change your cycle, but you"ll get up steam (鼓起干劲) and work better at your low
point. Get off to a slow start which saves your energy. Get up with a leisurely yawn and stretch. Sit on
the edge of the bed a minute before putting your feet on the floor. Avoid the troublesome search for
clean clothes by laying them out the night before. Whenever possible, do routine work in the afternoon
and save tasks requiring more energy or concentration for your sharper hours. |
| 1. If a person finds getting up early a problem, most probably ________. |
A. he is a lazy person
B. he refuses to follow his own energy cycle
C. he is not sure when his energy is low
D. he is at his peak in the afternoon or evening |

C. A change in a family member"s energy cycle.
D. Attempts to control the energy cycle of other family members. |
| 3. If one wants to work more efficiently at his low point in the morning, he should________. |
A . change his energy cycle
B. get up earlier than usual
C. overcome his laziness
D. go to bed earlier |
| 4. You are advised to rise with a yawn and stretch because it will ________. |

More than three billion people are at risk from indoor air pollution because of the heating or
cooking fuels they use. Most live in Africa, India and China. They use wood, crop waste, animal
waste or coal. These solid fuels may be the least costly fuels available. But they are also a major
cause of health problems and death.
The Aprovecho Research Center has been designing cooking stoves for the developing world.
People having less money use wood or biomass for cooking; the richer people use oil and gas. It"s
estimated that wood is running out more quickly than oil and gas.
The group has made stoves using mud, bricks, sheet metal, clay, ceramics and old oil drums.
Most of the stoves look like large, deep cooking pots. They have an opening at the bottom for the
fire and a place on the top to put a pot.
In the late 1970s, Aprovecho produced a popular stove called the Lorena. The Lorena was
good at reducing smoke and warming homes. But new tests years later found that it was not efficient.
The Lorena used twice as much wood as an open fire, and it took much longer to heat food. Since
then, they have experimented with countless other designs.
Their goal is to make an inexpensive stove-let"s say five dollars-that makes little smoke, and it"s
safe for health and reduces global warming and deforestation(采伐森林)．
Aprovecho has now partnered with a stove manufacturer in China. The company is making
Aprovecho"s first mass produced stoves. They are said to use 40%-50% less wood than an open
fire, and produce 50%-70% less smoke. A company called StoveTec is selling them through its
website for less than ten dollars. Dean Still says that more than one hundred thousand have been
sold so far. |
| 1. The underlined word "biomass" in Paragraph 2 refers to ________. |
A. oil and gas
B. wood
C. coal
D. crop waste or animal waste |
2. The following sentence is taken from the passage, it should be placed at the end of ________.
The World Health Organization estimates that over 1,500,000 people a year die from breathing smoke
from solid fuels. |
A. Paragraph 1.
B. Paragraph 2.
C. Paragraph 3.
D. Paragraph 4. |
| 3. Stoves designed by the Aprovecho Research Center should be ________. |
①luxurious
②costly
③efficient
④lowcarbon
⑤cleaner

Pregnancy(妊娠) and childbirth kill more than 536,000 women a year. More than half of the
cases happened in Africa, according to the World Health Organization. In fact, most of the deaths
are preventable with basic medical care.
The five leading causes are bleeding, infection, high blood pressure, longtime labor and bad
abortions (流产). Mothers" deaths from such causes were largely reduced nearly a century ago
in developed countries.
Experts say that what kill many women are "the three delays", the woman"s delay in deciding
to go to the hospital, the time she loses traveling there and the hospital"s delay in starting treatment.
Only about 15 percent of births have dangerous complications(并发症)．
Women lack education and information about birth control. Husbands and inlaws may decide
where a woman gives birth and insist that she stay at home to save money. However, there is no
single solution to a problem with so many factors shortages of doctors, nurses, drugs, equipment,
roads and transportation-though hospital officials are trying many things now.
One stopgap measure to solve the problem for the present has been to train assistant medical
officers, to perform certain operations. Some African countries are now struggling to train more
assistants and midwives(接生婆), and provide places for pregnant women to stay near hospitals.
But there is a long way to go. Only 20 percent of women in the continent give birth at the hospital.
More than 50 percent stay at home to give birth, and the rest go to local clinics that cannot handle
emergencies. |
| 1. Which is not included in the five leading causes of women"s deaths during pregnancy and childbirth? |
A. Infection.
B. High blood pressure.
C. Traveling long distances.
D. Bleeding. |
| 2. The underlined word "stopgap" probably means "________" in the passage. |
A. final
B. temporary
C. effective
D. instant |
| 3. What can we learn from this passage? |
A. Most problems that cause women"s deaths during pregnancy and childbirth can be treated or
prevented.
B. Developed countries should help African countries reduce mothers" deaths.
C. The husbands in poor countries should take responsibility for their wives" deaths.
D. The governments of African countries have to take more effective measures to save pregnant women. |
4. What is the author"s attitude towards the future of preventing women"s deaths during pregnancy and
childbirth? |
A. Positive.
B. Negative.

Are you preparing for a big test? If so, you may want to play some basketball in between hitting
the books. Doctors are starting to find more and more information that suggests a connection between
exercise and brain development. Judy Cameron, a scientist at Oregon Health and Oregon Health and
Science University, studies brain development. According to her research, it seems that exercise can
make blood vessels(管), including those in the brain, stronger and more fully developed. Dr. Cameron
claims this allows people who exercise to concentrate better. As she says, "While we already know
that exercise is good for the heart, exercise can really cause physical changes in the brain."
The effects of exercise on brain development can even be seen in babies. Babies who do activities
that require a lot of movement and physical activity show greater brain development than babies who
are less physically active. With babies, even a little movement can show big results. Margaret Barnes,
a pediatrician(儿科医生), believes in the importance of exercise. She thinks that many learning disabilities
that children have in elementary school or high school can be traced back to a lack of movement as
babies. "Babies need movement that stimulates their five senses. They need to establish a connection
between motion and memory. In this way, as they get older, children will begin to associate physical
activity with higher learning," says Margaret.
Older people can beef up their brains as well. Scientists from 11 universities studied a group of
seniors ranging in age from seventy to seventy-nine. Their study showed a short-term memory increase
of up to 40 percent after exercising just three hours a week. The exercise does not have to be very
difficult, but it does have to increase the heart rate. Also, just like the motion for infants (婴儿), exercise
for older people should involve some complexity. Learning some new skills or motions, such as with
yoga or tai-chi, helps to open up memory paths in the brain that may not have been used for a long
time.
For most people, any type of physical activity that increases the heart rate is helpful. The main goal
is to increase the brain"s flow of blood. And your brain can benefit from as little as three hours of exercise
a week. |
| 1. What is the best title of this passage? |
A. How to exercise
B. How exercise helps the brain
C. How to get good scores on a test
D. How the brain can change |
| 2. According to the reading, what is the connection between exercise and brain development? |
A. Exercise makes us stupid.
B. The brain needs special mental exercise.
C. The more exercise, the bigger the brain.
D. Physical exercise helps us think better. |
| 3. Why does the author think that yoga is fit for seniors? |
A. It is easy to learn.
B. It can be done in groups.
C. It does not increase the heart rate.
D. It includes learning new motions. |
