The bristlecone pine is the longest-living thing on the earth. These trees, with their strangely-shaped, wind-beaten limbs(枝干), can live up to 5000 years. But experts worry that a warming climate in some areas may threaten its future.
Researchers say warmer weather is permitting a similar kind of tree, the limber pine, to take over good growing places from the ancient bristlecone. They say the tree is being crowded out of mountainous areas where it grows.
“The bristlecone pine is the oldest individually growing organism,” researchers say. They grow in high mountain forests in eastern California, Nevada and Utah. In those mountains, the trees face high winds and extreme temperatures, which leave them with twisted limbs and shapes. “Even in such tough conditions,” Brian Smithers, a researcher at the University of California, said, “the limber pine is taking all the good spots.”
The limber pine is the bristlecone’s distant relative and competitor. It can also live a long time-up to 2000 years. And it is usually found at lower altitudes, where temperatures are warmer. However, according to a three-year study which centered on trees that have started growing in the last 50 years in California’s White Mountains, most of the trees growing at higher altitudes were limber pines.
Scientists compared the competing species to two old men in a very slow race up a mountainside. This race between such slow-growing trees takes thousands of years. They say climate change is causing the competition.
Smithers said the bristlecone pines are not in danger of disappearing. But he assumes they could be crowded out of some places where they have grown for thousands of years.
The researchers say the findings show how climate change can affect the two kinds of trees. The information, they say, can help scientists understand more complex forests.
1.What’s the function of Paragraph 1?
A.To introduce a topic. B.To summarize the whole passage.
C.To describe the appearance of a tree. D.To praise the hard work of the experts.
2.What does the underlined sentence in Paragraph 2 mean?
A.There will be older trees sent out of those mountains.
B.There will be more places covered with bristlecone pines.
C.There will be better limber pines replacing the ancient ones.
D.There will be fewer bristlecone pines growing in those areas.
3.According to the passage,the reason why limber pines can grow at higher altitudes is_________.
A.the high winds
B.the changing climate
C.the difficult conditions
D.the extreme temperatures
4.What is the researchers’ attitude towards the future of the bristlecone pine?
A.Positive. B.Negative. C.Concerned. D.Enthusiastic.

One of the statements that many experts seem to agree on is the fact that the great things starts to happen the minute you step outside of your comfort zones. As soon as you decide that you are willing to go beyond what is safe, the possibilities are endless. For me, one of the most important things that we should always keep in mind is the fact that growth and comfort can’t coexist.
Personal development author Napoleon Hill once said: “Whatever the mind can understand and believe, the mind can achieve. Regardless of how many times you may have failed in the past or how lofty(崇高的) your aims and hopes may be.” This statement is especially powerful because it reminds us that we are the only ones who can be responsible for how far we will go. However, stepping outside of our comfort zone is probably the most important step to experiencing real change.
For a long time, I knew that I wanted to live in Argentina, so halfway through my bachelor’s degree, I bought a one-way ticket there. While in Argentina, I finished the last two years of my degree online before flying back home for graduation. I currently still live in Argentina, and I can proudly say that taking the necessary steps to make it a reality was one of the most important things I could have done.
This, of course, by no means at all applies to everyone, and I’m not implying we should all buy one-way tickets to foreign countries and see what happens. But it’s important to know that we should recognize what we desire and try to bring our dreams to life.
Living in a comfort zone can trick us into believing that we have an abundant amount of time when, in reality, we all know that years can fly by without us having accomplished much of what we really wanted to do. So why wait? I’m thankful that I didn’t put off my move until a later date because I would have missed out on a lot of amazing life experiences that have shaped me as a person. If we want to experience even a small amount of change, we will have to step outside of it.
1.Why do people prefer staying in comfort zone?
A. It makes people feel safe.
B. It leads to great things.
C. It is important for growth.
D. It helps make wise decisions.
2.What does Napoleon Hill’s statement mean?
A. Time and tide wait for no man.
B. The higher you fly, the harder you fail.
C. Failure is the mother of success.
D. Nothing is impossible to a willing heart.
3.Which matters most to the author in his/her story?
A. Moving to Argentina.
B. Getting the bachelor’s degree.
C. Studying online.
D. Flying back for graduation.
4.The author used his/her story to ________.
A. persuade others to follow his/her example
B. encourage others to take immediate action
C. inform people of different foreign culture
D. remind people to be thankful in life
5.Which one could be the best title?
A. Identify your comfort zone.
B. Value your precious time.
C. Always try something new.
D. Make the best decisions.

One of the most fascinating things about television is the size of the audience. A novel can be on the “best seller” lists with a sale of up to 100,000 copies, but a popular TV show might have 70
million TV viewers. TV can make anything or anyone well-known overnight.
This is the principle behind “quiz” or “game” shows, which put ordinary people on TV to play a game for prizes and money. A quiz show can make anyone a star, and it can give away thousands of dollars. Charles Van Doren, an English instructor, became rich and famous after winning money on several shows. He even had a career as a television personality. But one of the losers proved that Charles Van Doren was cheating. It turned out that the show’s producers, who were pulling the strings, gave the answers to the most popular contestants beforehand. Why? Because if the audience didn’t like the person who won the game, they turned the show off. The result of this cheating was a huge scandal(丑闻). Based on the show off, a movie titled “Quiz Show” is on 40 years later.
Charles Van Doren is no longer involved with TV. But game shows are still here, though they aren’t taken seriously. In fact, some of them try to be as ridiculous as possible. There are shows that send strangers on vacation trips together, or that try to cause newly-married couples to fight on TV, or that punish losers by humiliating(羞辱) them. The entertainment now is to see what people will do just to be on TV. People still win money, but the real prize is to be in front of an audience of millions.
1.What is the most important thing as to television?
A. How many viewers they can attract B. Becoming the best seller on the list
C. How much money can be given away D. The number of people attending shows
2.What does the underlined part “pulling the strings” probably mean?
A. Planning the shows with effort B. Drawing the curtain on the stage
C. Controlling the result secretly D. Playing “quiz” or “game” openly
3.Charles Van Doren stopped his career as a television personality because ________.
A. he had earned enough wealth and fame.
B. one of the participants had told the truth
C. the film “Quiz Show” was being shown
D. his frequent appearance had bored the audience
4. It can be inferred from the passage that _______.
A. TV Game Shows are more popular than before.
B. the scandal was not made known until 40 years later
C. getting money is the only purpose of people taking part in shows
D. people can make themselves famous by taking part in shows

Everyone sleeps. However, taking the time to develop a sleep habit is probably the last thing on your mind and some sleep advice simply can’t be forgotten. 1. .
Watching TV until you fall asleep
It has nothing to do with what you watch--TV news isn’t a better pre-sleep choice than TV series. 2. . The bright light keeps you awake all the night. So even if you nod off (in front of the TV, for example), you probably won’t stay asleep for long.
Sleeping with pets
3. . They get comfortable, and then they move. This goes on all night, and whether you admit it or not, it interrupts your ability to get the level of sleep needed to feel rested.
Eating fatty, heavy foods too close to bedtime
Heartburn (烧心, 胃痛) strikes anyone of any age, but it’s the most common GI disorder (胃肠失调) in older adults. If you’ve ever tried to go to sleep after eating a fatty meal, you’ve probably found the discomfort of stomach preventing you from falling asleep or staying asleep.
4. Remember how poorly you sleep when you have a fever--turning over and over again, never really feeling rested? Well, heavy exercise too close to bedtime has the same effect--it raises your body temperature so that your sleep is disturbed until your body temperature drops to normal, which may take several hours.
Accepting snoring (打呼噜) as normal sleep behavior
Snoring may seem as common as breathing, but it’s considered the biggest sleep killer, and it’s linked to several causes: sleeping on your back, being overweight, having a cold, drinking, or taking drugs. 5. . For the snorer, it disturbs sleep by awakening him/her every so often in order to breathe normally. For the partner, the noise can be unbearable.
A. Exercising heavily too close to bedtime
B. Here are some suggestions you’ll need to follow
C. Reducing your body temperature before bedtime
D. Rather it’s the TV’s bright light that is the criminal
E. Here are some bad habits you need to get rid of
F. Most seriously, it’s caused by a dangerous illness
G. Pets sleep most of the day, and they move a lot when sleeping

On December 22, 2016 I landed in the land of the “American Dream.” 1. Here is one of the things I’ve struggled with during my almost one year in the States.
2. My uncle and aunt joked that I brought rain from Saigon to America. Saigon, where I come from, is the old name of Ho Chi Minh City in Vietnam. Vietnam is a tropical country where it rains most of the year. Before going to the U.S., actually, I had no idea what to expect about its weather, but the big rain on my arrival gave me the first expectation of what the weather here might be like.
California is known for having a great climate — more sunshine, cooler in summer and warmer in winter. 3. However, having been here for a pretty long while now, I have experienced various forms of climate in California.
4. Most of the time I was living in Silicon Valley, where the weather is a bit colder than where I study in Orange County. But I was really surprised to find chill-to-the-bone weather in San Francisco — a big shift from Silicon Valley in only about an hour’s drive. How strange!
5. The worst is that I get n runny nose whenever I wake up in the morning. Because I am allergic to the cold and windy weathers, I keep sneezing badly, and even more badly if I get caught in the cold. I think that my body needs more time to get used to this climate, but as many people said, I am luckier to be in California where I don’t have to fight with extreme weathers as in other stales.
A. I am sensitive to weather change.
B. Such strange weather has affected my health.
C. So the amount of rain this year is considered unusual.
D. LAX airport in California welcomed me with a big rain.
E. So I quickly get used lo the unchangeable climate in California.
F. The weather varies widely depending on where you are in the state.
G. Since then, I have discovered tons of dilemmas about life in America.

On a clear night, the sky is a wonderful thing. Is there life out there somewhere? Is there another place like Earth where life might exist? If so, where is it? And how far away is it?
Recently, the Kepler spacecraft found “22b”, a planet about six hundred light years away. It is the first planet in a “habitable zone” outside the solar system. That means the planet orbits(环绕) a star like our sun, but it is not too close to it, nor too far away. Because of this position, Kepler-22b might have water, one of the main things needed for life. The newly-discovered planet is about two and a half times larger than the Earth. It is closer to its star than we are to the Sun, but 22b’s sun is smaller than ours, and doesnt produce as much heat. Scientific instruments show the new planet could be made of gases, rocks or some kinds of liquids.
The Kepler spacecraft was named in honor of Johannes Kepler, the seventeenth century German astronomer. It was designed to examine a small part of the Milky Way galaxy(星系)and search for places like the Earth. It was made to inspect over 150,000 stars and measure how bright they are. It looks to see if a star’s brightness gets less over a short time.
If a planet passes between Kepler and the star, it blocks out part of the light. That is what suggested to scientists that there is at least one planet orbiting the star. The instruments on Kepler show the new planet as a small, black dot moving across its sun. An important part of the Kepler experiment is on the Earth. After the spacecraft gathers information, scientists use the telescopes on the ground.
Scientists have found over 2,300 new planets since Kepler was launched. Most are much larger, but it is the new planet’s distance from its star that is important. For life to possibly exist there, the planet’s temperature must not be too hot or too cold.
1. What can we learn about Kepler-22b?
A. Water must have existed on it.
B. It takes humans about 600 years to get there.
C. It is made of gases, rocks and plenty of liquids.
D. It is the first planet in outer space where life may survive
2. The Kepler spacecraft was sent into space to
A. show honor to Johannes Kepler
B. observe the changes of a star’s brightness
C. look for Earth-like planets in the Milky Way galaxy
D. measure the brightest star among 150.000 stars
3.In Paragraph 4 the author mainly tells us
A. how the Kepler system works
B. if the Kepler system sees a new planet
C. how the Kepler system shows a new planet
D. why an important part of the Kepler system remains on the Earth
4. What can we infer from the passage?
A. Life may exist on the new planet in another form.
B. It is colder on the new planet because its sun is smaller.
C. Life can’t exist on planets which are much larger than the Earth.
D. The new planet’s distance from its star decides on the possibility of life existence.
