ient lake on Mars recently, increasing hopes of discovering evidence that billions of years ago the Red planet hosted life.
The lake, which dates back some 3.4 billion years, appears to have covered as much as 80
square miles and was up to 1,500 feet deep, said the team from the U
niversity of Colorado."This is the first clear evidence of shorelines on the surface of Mars,"said Boulder" s research
associate, Gaetano Di Achille, in a study published in the latest edition of Geophysical Research
Letters.
"The identification of the shorelines and accompanying geological evidence allows us to calculate
the size and volume of the lake, which appears to have formed about 3.4 billion years ago."
Analysi
s of the images has shown the water carved out the canyon (溪谷) in which it was found, which then opened out into a valley depositing (使淤积) sediment (沉积) which formed a delta
(三角洲).
"Finding shorelines is a great discovery to us," said assistant professor Brian Hynek, adding it
showed the lake existed at a time when Mars was thought to have been cold and dry.
Scientists believe the oldest surfaces on Mars formed during the wet and warm era known as the
Noachan epoch, about 4.1 billion to 3.7 billion years ago.
The newly discovered lake is believed to date from the Hesperian era and postdates the end of the
warm and wet period on Mars by 300 million years, according to the study.
Scientists believe deltas next to the lake may well hold secrets about past life on Mars as such places
on Earth have become the natural deposits of organic carbon and other markers of life.
1. The size of the lake found on Mars is ______.
A. 80 square miles
B. 1,500 square miles
C. 3.4 billion square miles
D. 300 million square miles
2. When the lake existed, the weather on Mars was ____.
A. hot and wet
B. wet and warm
C. cold and dry
D. cold and wet
3. Why do scientists think deltas near the lake may hold secrets about past life on Mars?
A. Because similar places on Earth have become natural deposits of marker
s of life. B. Because someone has put secrets about past life on Mars there.
C. Because past life has been found in other deltas on Mars.
D. Because some people are said to have already seen life marks there.
4. Which of the following statements is NOT true according to the passage?
A. The Noachan epoch was a wet and warm era.
B. The lake might have existed 3.4 billion years.
C. The discovery can" t fully prove that the Mars once hosted life.
D. The lake traces prove that there exists life on Mars now.

举一反三
Are you truly happy? Do you ever know what it means to be happy and what it takes to achieve
happiness? 1 . The following are a few tips that I follow to create happiness in my life.
Make a plan for attaining goals that you believe will make you happy. Your moods will very likely
increase if you are going after something you value.
Surround yourself with happy people. It is easy to begin to think negatively when you are surrounded
by people who think that way. 2 .
When something goes wrong, try to figure out a solution instead of being absorbed in self pity. Truly
happy people don" t allow setbacks to affect their mood because they know that with a little thought they
can turn the circumstances back to their favor.
3 . These few minutes will give you the opportunity to focus on the positive things in your life and
will lead you to continuous happiness.
4 . Whether you treat yourself to lunch, take a long, relaxing bath or simply spend a few extra
minutes on your appearance, you will be subconsciously (下意识地) putting yourself in a better mood.
Finding the humor in situations can also lead to happiness. Find a way to make light of a situation that
would otherwise make you happy.
Keeping healthy is an
other way to achieve happiness. 5 .A. What makes one person happy may be very different from what makes someone else happy.

of the country have pros and cons.
GOOD NEWS
Free museums. No charge for outstanding collections of art and antiquities.
Pop music. Britain is the only country to rival(与…匹敌)the US on this score.
Black cabs. London taxi drivers know where they ar
e going even if there are never enough of them
at weekends or night.
Choice of food. Visitors can find everything from Ethiopian to Swedish restaurants.
Fashion. Not only do fashion junkies love deeply and respect highly brand names such as Vivienne
Westwood, Alexander McQueen; street styles are justly loved, too.
BAD NEWS
Poor service. "It"s part of the image of the place. People can dine out on the rudeness they have
experienced," says Professor Tony Seaton, of Luton University"s International Tourism Research Center.
Poor public transport. Trains and buses are promised to defeat the keenest tourists, although the
over crowded London tube is inexplicably(难以理解的) popular.
Lack of languages. Speaking slowly and clearly may not get many foreign visito
rs very far, even in
the tourist traps(圈套).
Rain. Still in the number one complaint.
No air-conditioning. So that even splendidly hot summers become as unbearable as the downpours.
Overpriced hotels. The only European country with a higher rate of tax on hotel rooms is Denmark.

time and money! Best of all, it is free!
It"s "no".
What do you ask? We"ll say it again: "No".
Sweet and simple "no".
Say "no" at your office and see how quickly that pile of work on your desk disappears.
"Saying "no" to others means you are saying "yes" to yourself, " said Leslie Charles, a professional
speaker from East Lansing, Michigan.
"Time is precious. People are spending money buying ti
me. And yet we are willing to give up our time because we can"t say "no"."
Susie Watson, a famous writer, said people who always say "yes" need to say "no" without guilt(内
疚)or fear of punis
hment. "I would rather have someone give me a loving "no" than an obligated(强制的)"yes", " she said.
Susie Watson says she feels "no" obligation to give an explanation when she says "no" either socially
or professionally. Does she feel guilty about it? "Not at all," said Watson, who is director of advertising
and public relations at Timex Corp in Middlebury, Conneticut. "Most people are afraid of saying "no"…
My advice is to say "yes" only if you don"t mean "no"."
Watson said "no" is the most effective weapon against wasting time. "Every year there are more
demands on your time… Other people are happy to use up your time. " Watson said. Time saving
appears to be "no"s" greatest friend.
"No" can be your new friend, a powerful tool to take back your life. "No" may even tak
e you further in the business world than "yes".
"No" is power and strength. "No" now seems completely correct. "Saying "no" isn"t easy. But finally
it"s greatly liberating," Charles said. But, he adde
d, a "no" project needs to be worked on every day because it is hard to change long-term habit.
But, he also warns: "Don"t go to extremes. Don"t find yourself saying "no" to everything. In return you
should learn to hear "no"."

not a nation of walled gardens and closed gates. Their yards normally run into one another without fences,
they often visit one another"s homes without being invited or telephoning first, they leave their office doors
open while they work.
Their lack of desire for privacy probable results from their history as a nation. America is a big
country. There have never been walled cities in the United States, nor was there the need for Americans
to protect themselves from neighboring states. During the early years, America had so few settlers that
neighbors were very important, they were not to be shut out by doors and fences. Neighbors offered
protection and helped in the hard work of settling the la
nd. They depended upon each other. From the nation"s early history has come the desire for openness rather than privacy. Visitors will
notice this desire in a number of small ways, there may be rooms in American homes that do not have
doors or that have glass walls. If you notice that people forget to close your door when they leave your
room, do not think that this is rude, help them to learn that you would like it to be closed, or else become
used to new ways. In either case, be patient with the differences.

ding to the passage, visitors to America sometimes have difficulty understanding ___.A. Americans" openness

4. Which

dreamed something that came true later? Maybe you have ESP(超感觉的知觉).
ESP stands for Extrasensory Perception. It may be called a sixth sense. It seems to let people know
about events before they happen, or events that are happening some distance away.
Here"s an example. A woman was ironing clothes. Suddenly she screamed, "My father is dead! I
saw him sitting in the chair!" Just then, a telegram came.
The woman"s father died of a heart attack. He died sitting in a chair.
There are thousands of stories like this one on record. Scientists are studying them t
o find outwhat"s behind these strange mental messages. Here"s another
example-one of hundreds of dreams that have come true.
A man dreamed he was walking along a road when a horse and a carriage came by. The driver
said, "There"s room for one more." The man felt the driver seemed dead, so he ran away. The next day,
when the man was getting on a crowded bus, the bus driver said, "There"s room for one more."
Then the man saw that the driver"s face was the same face he had seen in the dream. He wouldn"t
get on the bus. As the bus drove off, it crashed and burst into flames. Everyone was killed!
Some people say stories like this are coincidences. Others, including some scientists, say that ESP
is real. From studies of ESP, we may someday learn more about the human mind.

A. in existence

3. By studying ESP, scientists may get to ______.
A. learn how people tell lies
B. know more about human dreams
C. know more about human mind
D. learn how strange things happen
4. In the last paragraph, the underlined word "coincidences" probably means ______.
