It is one of the greatest mysteries of nature. In case you haven’t noticed, all living things follow very definite, individual rhythms, all as regular as a clock, but what makes them regular?
Though many scientists maintain that these rhythms are the result of some outside force like gravity or radiation or both, the results of most scientific researches agree with other scientists who believe that each living thing has its own built-in biological “time clock.”
Take the mystery of migration for example. Scientists can’t really explain why many species of birds migrate in the autumn even though the temperature is still summery. The birds just seem to snub the comfortable weather that they are having. When a certain time comes, they travel south by the thousand. In spring time, they migrate northwards even though there probably is snow still covering the ground when they finally arrive. Something said “go,” and they did.
Animals that hibernate (冬眠) are obeying individual time clocks, too. When their clock indicates the time to take a winter’s nap, they do, and nothing can stop them. At a certain time in the spring, they wake up and come out regardless of the weather outside.
Plants appear to have yearly rhythms, such as the sprouting of seeds, and they also have daily rhythms. Notice sometimes that plants raise their leaves in daylight and lower them at night.
If you live along the California coast, you can easily observe a demonstration of this mysterious clock functioning regularly. There, from February to September, the highest tides occur exactly every fourteen and four-fifths days, and during these high tides, but at no other time, small silvery fish called grunions surf-ride a wave to the beach. There the female deposits her eggs in the sand and the male fertilizes them; then both hitch a wave-ride back to the sea. Exactly fourteen and four-fifths days later, never before or after, the tiny eggs hatch, and the high tide carries the new babies out to sea.
72. According to the passage, the mysterious rhythms result from ______.
A. the influence of gravity on living species
B. the effect of radiation on living species
C. the influence of a mysterious outer force on living species
D. the internal mechanism inside the living species
73. The underlined word “snub” in the third paragraph probably means ______.
A. fight B. ignore C. symbolize D. criticize
74. Which of the following statements is NOT TRUE?
A. Hibernating animals are obeying an internal time clock.
B. The positioning of the leaves of some plants is due to the daily rhythms.
C. The internal clock functioning is demonstrated in the reproducing habits of grunions.
D. The yearly hibernation is more because of the weather influence than the biological functioning.
75. The passage is mainly about ______.
A. the rhythms of life
B. the reasons of mysterious hibernation
C. strange behaviors of species
D. the timing for different events in the world of species

You must have been troubled by when to say “I love you” because it is one of the greatest puzzles in our life.
What if you say it first and your partner doesn’t love you back? Or if they do say it but you don’t feel they mean it? Being the first to declare your love can be nerve racking(紧张）and risky and can leave you feeling as vulnerable as a turtle with no shell. But is the person who says it first really in a position of weakness? Doesn’t it pay to hold back, play it cool and wait until the other half has shown their hand fast?
A really good relationship should be about “being fair and being equal,” says psychologist Sidney Crown. “But love is seldom equal.” All relationships go through power struggles but, he says, if a love imbalance continues for years, the rot will set in. “That feeling of ‘I’ve always loved you more’ may be subverted(颠覆，破坏) for a time, but it never goes away completely and it often emerges in squabbling(大声争吵).” In love, at least, the silent, withholding type is not always the most powerful. “The strongest one in a relationship is often the person who feels confident enough to talk about their feelings,” says educational psychologist Ingrid Collins. Psychosexual therapist Paula Hall agrees. “The one with the upper hand is often the person who takes the initiative. In fact, the person who says ‘I love you’ first may also be the one who says ‘I’ m bored with you’ first.” Hall believes that much depends on how “I love you” is said and the motivation of the person saying it. “Is it said when they’re drunk? Is it said before their partner files off on holiday, and what it really means is ‘Please don’ t be unfaithful to me’ ?” By saying ‘I love you’, they are really saying ‘Do you love me?’ If so, wouldn’t it just be more honest to say that. Collins agrees that intention is everything. “It’s not what is said, but how it’s said. What it comes down to is the sincerity of the speaker.”
1. What is the main idea of this passage?
A. The importance of “I love you”
B. The meaning of “I love you”
C. The time of saying “I love you”
D. The place of saying “I love you”
2. In the first sentence the author means that _________.
A. it is easy to say “I love you”
B. it is hard to say “I love you”
C. we have many troubles in our life
D. people usually do not know when to say “I love you”
3. According to the expert, a good relationship should be _______.
A. fair and equal B. fair and kind

4. In the third paragraph, the phrase “with the upper hand” means _________.

Queensland is one of the most amazing states in Australia. It has some of the most beautiful natural scenery on the planet, with the Great Barrier Reef, rainforests and impressive beaches.
The Great Barrier Reef
It is one of the world’s largest natural features. It stretches more that 2,300 km along the north eastern coast of Australia from the northern tip of Queensland to just north of Bundaberg. The things that most surprise visitors to the reef are the colors.
Without doubt, the best way to see the Great Barrier Reef is by diving. If you have a little extra money and you are feeling a bit lazy, you can fly over the reef in a plane.
Fraser Island
Another area of natural beauty is Fraser Island. This is the world’s largest sand island. It’s best visited from Hervey Bay on the mainland, where there are a number of places offering trips around the island. To fully appreciate Fraser Island you should go for three or four days. Attractions include some beautiful fresh-water lakes, particularly Lake Wabby and Lake Mckenzie. You can walk around these on white sands untouched by human footprints. Indian Head also has some beautiful views. Braver travelers can go and watch sharks circling the water hundreds of meters below.
The Whitsunday Islands
It would be a pity to travel around Queensland without taking a trip around the Whitsunday Islands. They were named by Captain Cook in 1770, after the day on which he arrived. Here are some of the great things you can do there.
●Cruise around them on a relaxing trip.
●Take a sailing course.
●Look at the aboriginal (土著的) paintings in caves on Hook Island.
●Have fun in the water doing lots of water sports.
So, will you be going to Queensland?
1.The best way to admire the beauty of the Great Barrier Reef is .

Crown shyness(树冠羞避) is a mysterious natural phenomenon in which the crowns of some tree species do not touch each other, but get separated by a gap clearly visible from ground level. The effect usually occurs between trees of the same species, but has also been observed between trees of different species.
There are many theories going around, most of which make sense, but no one has been able to prove without the shadow of a doubt why some trees avoid touching each other.
In his 1955 book Growth Habits of the Eucalypts, Australian forester M.R. Jacobs writes that the growing tips of the trees are sensitive to abrasion(擦伤), which results in crown shyness phenomenon. This theory was also supported by Dr. Miguel Franco. Some experiments have shown that if trees displaying crown shyness are artificially prevented from swinging in the wind and touching each other, they gradually fill up the gaps between them.
But while the above theory is arguably the most widespread, it’s certainly not the only one. Some scientists have suggested that crown shyness is a mechanism to stop the spreading of leaf-eating insects. These pests have been known to work together and create structures that extend up to 10 cm off of tree branches in order to reach other plants, so the gaps are the trees’ natural defense method.
One Malaysian scholar studied many trees, but found no traces of abrasions, despite their clear crown shyness. Instead, he suggests that the growing tips of the trees were sensitive to light levels and stopped growing when they got too close to other trees. Plants are able to sense how close they are to other plants and in order to get more light, they give off some chemical element to stop other trees from growing too close.
Whatever the reason, one thing is for sure: plants are more intelligent than people used to think.
1.What can we know about crown shyness?
A. It can cause abrasion between trees.
B. It only happens between the same species.
C. It has been discovered for only half a century.
D. No agreement has been reached about its real cause.
2.What will happen if trees showing crown shyness are stopped from swinging?
A. The trees will stop growing and even die.
B. The gaps between the trees will grow wider.
C. The crown shyness phenomenon will disappear.
D. The gaps between the trees will remain the same.
3.What’s tree’s reaction when attacked by pests according to the text?
A. Swinging less in the wind
B. Leaving space between their crowns
C. Spreading their branches and leaves
D. Stopping growing for a period of time
4.Which statement might the Malaysian scholar agree with?
A. Trees have special ways to attack others.
B. Some insects stop trees growing too close.
C. Trees compete with their neighbors for light.
D. Trees won’t touch each other to avoid diseases.

How the Grand Canyon (大峡谷) was created remains one of the geology’s greatest mysteries. Some evidence suggests that the process was a gradual one in which the Colorado River (which runs through the canyon) slowly cut deeper and deeper into the ground over millions of years. But volcanic rock samples taken from the canyon now suggest that the canyon was down-cut instead.
Down-cutting is when a flood of water rushes over a landscape (地形) with enough force to cut deeply into the ground and leaves behind a canyon. Such a flood is usually released when a natural or man-made dam (堤坝) bursts.
Robert Webb, a research geologist, says natural dams seem to have formed and broken across the Colorado River several times during the last million years. The dams were built when lava(熔岩) from the eruptions of nearby volcanoes flowed into the river. The lava hardened into hard rocks and blocked the river, causing it to back up and form a lake. Each time the lake grew so huge that it broke the rock dam, releasing a flash flood
that furthered the down-cutting process and deepened the canyon.Down-cutting is not just an earthly event. Satellite photos sent back from Mars suggest th
at the process has happened there, too, say many other researchers.The photos, taken by the Mars Global Surveyor, indicate that an enormous lake existed on Mars 3.5 billion years ago. The lake spilled into a large nearby hole. One edge of the hole broke, releasing a flash flood that quickly carved out a grand canyon.
The existence of down-cutting on Mars is just one more piece of evidence that the cold, dry planet was
once warm and wet.1.In the past, deep canyons were believed to have formed _______.
A. as a result of a sudden break of volcanoes
B. due to river flows over millions of years
C. owing to the burst of artificial dams
D. thanks to our ancestors’ creative work
2.According to the passage, which of the following statements is TURE?
A. Several volcanoes broke out on Mars directly creating grand canyons.
B. Several great lakes existed on the upper parts of the Colorado River.
C. People built high dams on the upper parts of the Colorado River.
D. The Colorado River crossed the Grand Canyon to form down-cutting.
3.From the last three paragraphs we learn that _______.
A. there are great lakes on Mars
B. there are active volcanoes on Mars
C. there might be cities on Mars
D. there might be life on Mars
4.The passage can be titled as _______.
A. Lakes on Earth and Mars
B. The Cause of Lake Formation

One of the greatest sources of unhappiness, in my experience, is the difficulty we have in accepting things as they are.
When we see something we don’t like, we wish it could be different -- we cry out for something better. That may be human nature, or perhaps it’s something that’s ingrained（根深蒂固的）in our culture.
The root of unhappiness is that we decided we didn’t like it in the first place. We’ve judged it as bad, rather than saying, “It’s not bad or good, as it just is.”
An example: in my recent post（帖子）, A Beautiful Method to Find Peace of Mind, quite a few commentators thought my outlook was negative, pessimistic, or fatalistic（听天由命的）... because I said you should expect people to mess up, expect things to go differently from what you planned. Above all, you should embrace that.
It’s too negative to expect something to go wrong, they said. However, I think it’s only negative if you see it as negative, or if you judge it as bad.
Instead, you could accept it as the way the world works -- as the way things actually are. And try to understand why they are that way.
Does it mean you can never change things? Not at all. But changing things is not because you can’t accept things as they are, but because you enjoy the process of change of learning and growing.
Can we make this world a better place? Again, that’s an assumption that it’s a bad place fight now. But instead, you could say the world is just what it is -- and that’s neither good nor bad. You can say that you’ll continue to try to do things to help others, to grow as a person, to make a difference in this world -- not because you’re such a bad person now, but because that’s the path you choose to take, because you enjoy that path.
As you catch yourself judging, and wishing for different -- try a different approach: accept, and understand. It might lead to some interesting results.
1. Which of the following statements is correct according to the author?
A. We can never change things because we can’t accept them.
B. We shouldn’t try to do whatever we can to help others and make a difference.
C. It’s wrong of you to expect things to go differently.
D. There is nothing either good or bad, but thinking makes it so.
2. What’s the main idea of the whole passage?
A. The world is a good place for us to live in.
B. Unhappiness comes from what we want to be different.
C. You might as well accept the world as it is and try to embrace it.
D. Let’s make the world more beautiful.
3.Where does the passage probably come from?
A. A novel. B. A news story. C. A travel guide. D. A magazine.

When we see something we don't like, we wish it could be different. We cry out for something better. That may be human nature, or perhaps it’s something ingrained(根深蒂固的) in our culture.

We've judged it as bad, rather than saying, “It's not bad or good, and it just is it. ”
In one of my books, I said “You should expect people to mess up and expect things to go differently than you planned”. Some readers said it’s too sorrowful to expect things to go wrong. However, it's only negative if you see it as negative and judge it as bad. Instead, you could accept it as the way the world works and try to understand why that is.
This can be applied to whatever you do: how other people act at work, how politics works and how depressing the news media can be. Accept these things as they are, and try to understand why they're that way. It will save you a lot of sadness, because you'll no longer say, “Oh. I wish bad things didn't happen!”
Does it mean you can never change things? Not at all. But change things not because you can't accept things as they are, but because you enjoy the process of changing, learning and growing.
Can we make this world a better place? You can say that you’ll continue to try to do things to help others, to grow as a person, to make a difference in this world.

A. it is our natural emotion in the life

A. Acting well at work and in politics.
