Scientists have found what look like caves on Mars (火星), and say they could be protecting life from
the planet"s terrible environment.
The first caves discovered beyond the Earth appear as seven anysterious black dots on the pictures sent
back by NASA"s Mars Odyssey orbiter. Each as large as a football field, they may be openings into natural
caves below the Martian suface.
"If there is life on Mars, there is a good chance you"d find it in caves," said Jut Wynne, one of the
researchers who noticed the features while working on a US Geological Survey Mars Cave Detection
Program.
Jonathan Clarke, a geologist with the Mars Society of Australia, yesterday described the discovery as
exciting.
One photo taken at night by an infrared imager (红外线成像器) showed one hole to be unusualy warm,
suggesting hot air trapped during the day is flowing out.
"I said:"Wow, that"s a cave"" Dr. Clarke said excitedly." People have been looking for these for a long
time; now we have found them."
He agreed such caves would be perfect places to hunt for life escaping from the bitterly cold,
radiation-soaked (充满辐射的), dry surface.
"Tiny drops of water could collect inside," he said. "If there are gases coming out, they could provide
energy for a whole range of bacteria. A cave is also a protection from radiation; the surface of Mars is
exposed to high levels of space radiation."
The caves probably formed when tube-shaped lave flows (管状岩浆流) spread across the planet long
ago. The outside of the tubes cooled, forming solid walls, while something hotter inside allowed the
remaining have to flow out, forming caves.
B. How scientists found these caves on Mars.
C. Caves on Mars may be full of hot air or a sign of life.
D. Scientist have completely recognized the surface of Mars.
B. the scientists found all the caves at night
C. it is certain that there is life in these caves
D. the surface of Mars is bitterly cold, radiation-soaked and dry
B. they had finally found the caves on Mars
C. such caves would be perfect places to hunt for life
D. scientists had long been looking for these caves
B. water and radiation from space
C. gases and lava
D. water and protection from radiation

Arctic and is now angling toward Siberia.
Not to be confused with the geographic North Pole-the northern extremity of the Earth"s axis (地轴),
the north magnetic pole (where the Earth"s magnetic field is directed downward) is moving due to natural
changes in the Earth"s magnetic field, a process that originates about 3, 000 kilometers below our feet, in
the outer core (核心) of the planet. But scientists are now noticing that the magnetic pole has picked up
its pace.
Over the past century, the pole has been migrating at an average speed of about 10 kilometers per year,
says Larry Newitt, head of Geomagnetic Laboratory at Natural Resources Canada in Ottawa. Since the
1970s, this speed has increased to about 50 kilometers per year.
Scientists are wondering why the speed is increasing, says Newitt. One Hypothesis (假说) relates it to
"magnetic jerks", sudden shifts (变化) in the rate of change of the magnetic field. There have been three
jerks in the past four decades, each one correlating to an increase in speed.
If the north magnetic pole continues at its current rate, it could reach Siberia by 2056.
"For most of recorded history, the pole has been a part of Canada, and now it"s not," says Newitt. "It
may be a blow to our collective psyche, but other than that, it doesn"t have a major effect on most people"s
existence. 73. Find in the passage a word closest in meaning to the underlined word "angling".

to move forward or threatened and thinking of moving back, a study has found.
Researchers in Italy examined the tail wagging behavior of 30 dogs, catching their responses to a range
of stimuli (刺激物) with video cameras. To conduct the study they chose 15 male dogs and 15 female ones
aged between one and six years. The dogs were all family pets whose owners had allowed them to take part
in the experiment at Bari University. The dogs were placed in a large wooden box with an opening at the front
to allow for them to view various stimuli. They were tested one at a time.
The researchers led by Professor Giorgio Vallortigara of the University of Trieste found that when the
dogs were shown their owners-a positive experience-their tails wagged energetically to the right side. When
they were shown an unfamiliar human they wagged to the right, but with somewhat less enthusiasm. The
appears of a cat again caused a right-hand side wag, although with less intensity again. The appearance of a
large unfamiliar dog, similar to a German shepherd, changed the direction of tail wagging to the left. Research
ers supposed the dog was thinking of moving back. When the dogs were not shown any stimuli they tended
to wag their tails to the left, suggesting they preferred company. While the changes in the tail wagging were
not easily noticed without the aid of video, it was thought that the findings could help people judge the mood
(心情) of dogs. Computer and video systems, for example, could be used by professional dog trainers to
determine the mood of dogs that they were required to approach.
B. the dogs were put in the wooden boxes and tested one at a time.
C. they enabled the dogs"owners to know about their dogs"habit
D. the dogs wagged their tails in different directions when they were in different moods
B. worry
C. excitement
D. interest
B. wag to the right
C. not wag at all
D. wag to the left and then to the right
B. the trainers
C. the systems
D. the researchers
B. to help people judge the mood of dogs
C. to help dogs find company
D. to help people choose their pet dogs
of sunshine. The warmth of the land heats the air above, causing it to rise and tiny drops of water to fall as
rain. The rainfall can reach at least 98 inches a year. This wet, warm world with plenty of sunlight is perfect
for plants to grow, so the trees grow fast with green leaves all the year round. The trees themselves also hare
an effect on the climate. They gather water from the soil and pass it out into the air through their leaves. The
wet air then forms clouds, which hang over the treetops like smoke. These clouds protect the forest from the
daytime heat and night-time cold of nearby deserts, keep temperatures fit for plant growth.
Rain forests slightly farther away from the equator remain just as warm, but they have a dry season of three
months or more when little rain falls, Tree leaves fall dining this dry season and new leaves grow when the wet
season or monsoon (雨季) begins Thus these areas are known as the "monsoon forest".
Another type of rain forest grows on tropical mountains. It is often called the "cloud forest" because clouds
often hang over the trees like fog.
The rain forest is the ideal place for the growth of many different trees. Most of them depend on animals to
eat their fruits and spread their seeds. When the fruits are eaten, the seeds inside them go undamaged through
animals, stomachs and are passed out in their droppings. The seeds lying on the forest floor then grow into
new trees.
B. hot, rainy and foggy
C. hot, wet and cloudy
D. warm, wet and sunny
B. there is a dry season in the cloud forest on tropical mountains
C. clouds help the plants in the rain forest near the deserts to grow
D. the formation of climate in the rain forest has little to do with the trees
B. droppings
C. fruits
D. winds
B. a story book
C. a technical report
D. a geography book
only a 1050." The unlucky students are speaking of the score on the Scholastic Aptitude Test (SAT),
which is used to determine whether they will be admitted to the college or university of their choice, or
even have a chance to get a higher education at all. The SAT score, whether it is 800, 1 100 or 1550, has
becomes the focus at this time of their life.
It is obvious that if students value highly their test scores, then a great amount of their self-respect is
put in the number. Students who perform poorly on the exam are left feeling that it is all over. The low test
score, they think, will make it impossible for them to get into a good college. And without a degree from a
prestigious university, they fear that many of life"s doors will remain forever closed.
According to a study done in the 1990s, the SAT is only a reliable indicator of a student"s future
performance in most cases. Interestingly, it becomes much more accurate when it is set together with other
indication--like a student"s high school grades. Even if standard tests like the SAT could show a student"s
academic proficiency (学业水平),they will never be able to test things like confidence, efforts and willpower,
and are unable to give us the full picture of a student"s potentialities (潜力). This is not to suggest that we
should stop using SAT scores in our college admission process. The SAT is an excellent test in many ways,
and the score is still a useful means of testing students. However, it should be only one of many methods
used.
B. academic ability
C. full potentialities
D. confidence in school work
B. achievements in mathematic
C. job opportunities
D. money spent on education
B. a technical university
C. a traditional university
D. an expensive university
B. stress caused by the SAT
C. American higher education
D. the SAT and its effects
Kate"s weakness is more acceptable-she is unable to walk past a cake shop without overeating Sophin Cartier
finds her cigarette habit a headache, while Alice"s thumb-sucking drives her boy friend crazy. Four people
with very different habits, but they all share a common problem anxiety disorder or, in serious cases. Obessive
Compulsive Disorder (OCD).
From nail-biting to too much hand-washing, overeating and internet addiction (上瘾),OCD is widespread
in almost every workplace and countless home."It is a relatively common form of anxiety," says Dr. Mootee.
"The main feature of OCD is the repetition of unwanted obsessive (过度的) thoughts such as worries that
doors are left unlocked, gas or electrical appliances are left on." In order to fight against the an essay checking
door locks and gas or electrical appliances.
Dr. Mootee says that repetitive washing, particularly of the hands, is the most common type of OCD. She
has treated many patients who wash their hands up to 30 times a day. The technique Mootee uses to treat
people with OCD is called cognitive-behavioral therapy (认知行为疗法). "It is based on the general idea that
people have the ability to change the way they think and behave," says Mootee.
But when does a habit become a problem? "It"s personal," says Mootee. "Everyone has something unusual,
but if you can"t put up with it, then it"s a problem and you need to do something to change it." Mootee says
many people ready for treatment because they fear they are "crazy". But as people become more knowledgeable about these problems they will go and get help. The only way to cure is to conquer.
B. hurting himself
C. sucking fingers
D. biting nails
B. gets into unwanted habits to relieve stress
C. has unwanted thoughts about habits
D. has unwanted thoughts because of illness
