Many people may not believe it, but this is what is happening: polar bears are dying out! They are dying because they are losing a great deal of habitat due to human incursion（侵入）and global warming. They are dying because of starvation as well. With the sea ice they depend on for survival shrinking, it is becoming increasingly difficult for them to find food.
An ecosystem is highly dependent on all of its parts, and removing even a single species can result in serious consequences. Polar bears are at the top of the predators（捕食性动物）where they live. They play an important part in the ecosystem. They feed on seals, fish and deer. Several other animals depend on the kill of polar bears. The failure to save polar bears might result in loss of these predators.
In addition, all large predators perform a very important function in their habitat: helping to control the populations of other species. When an animal group loses its natural predators, its population will rise rapidly, having a direct result in population decrease of other groups. A huge boom in population of Arctic seals would have a direct effect on the prey(捕食) of seals, and could reduce numbers of certain types of fish.
This could also have a direct effect on humans, who might have to compete with Arctic seals for food supplies from fish. Lack of polar bears could eventually affect human food supply. Human beings shall save polar bears to ensure the food supply.
There is no doubt that we should save polar bears. However, there is still another question: can they be saved? This is a matter that scientists debate because of rapid degradation（恶化）of the polar bear’ environment in recent years due to warming temperatures. It is estimated that if the bears cannot adapt to changing climates, they might die out before the end of the 21st century, with about 50% of the animals disappearing by 2050. So time is running out!
There are some things that may help slow down global warming and help delay extinction of polar bears. These include finding new energy sources that don’t give off greenhouse gases and not making any more incursions into polar bear’s territory.
Which is NOT the threat to the survival of polar bears according to the passage?
| A．Human’s killing. | B．Global warming. |
| C．Habitat loss. | D．Lack of food. |
Why do we need to save polar bears?
| A．For the predators in the ecosystem. |
| B．For the seals in Arctic Circle. |
| C．For our own source of food. |

If bears can’t adapt to changing climates, we will probably have lost _____ by the middle of the 21st century.
| A．half of polar bears |
| B．most of polar bears |
| C．90% of polar bears |
| D．all of polar bears |
We can infer that _____ .
| A．nothing can prevent the extinction of polar bears |
| B．drilling for oil in the Arctic should be encouraged |
| C．polar bears can surely adapt to changing climates |
| D．using solar energy is good for saving polar bears |
First lady Michelle Obama has some advice for some Tennessee High School graduates: Strike your own path in college and life and work to overcome(克服) difficulties with determination and courage.
The first lady told the 170 graduates that she spent too much of her own time in college focusing on academic achievements. While her success in college and law school led to a good job, she said, she ended up leaving to focus on public service.
“My message to all of you today is this: Do not waste a minute living someone else’s dream.” she said. “It takes a lot of real work to discover what brings you joy… and you won’t find what you love simply by checking boxes or padding your GPA(夸大成绩).”
She said the school reminded her of her own high school experience in Chicago. “My No. 1 goal was to go to a high school that would push me and challenge me.” she said. “I wanted to go somewhere that would celebrate achievement, a place where academic success wouldn’t make me a target(目标) of laughing at or bullying, but instead would be a badge of honour(荣誉的象征).” But Mrs. Obama said pitifully that not all students have the same opportunities. “Unfortunately, schools like this don’t exist for every kid,” she said. “You are lucky.”
The first lady told graduates that failure may be a part of their college lives and careers, and that how they respond to any difficulties will define them. “That’s when you find out what you’re really made of in those hard times.” she said. “But you only do that if you’re willing to put yourself in a position where you might fall.”
Overcoming difficulties has been the hallmark(特征) of many great people, she said. “There’s this guy Barack Obama… he lost his first race for Congress, and now he gets to call himself my husband.” The first lady joked: “I could spend a whole afternoon talking about his failures.”
What’s the purpose(目的) of Michelle’s visit to Tennessee High School?
| A．To give a speech to the graduates. | B．To help Obama win respect. |
| C．To welcome new students. | D．To give the graduates some advice. |
According to Michelle, _________.
| A．it’s enough for the students to study well at school |
| B．she was a target of laughing at or bullying when studying at school |
| C．it’s lucky for the students to study at Tennessee High School |
| D．most great people met with difficulties on their way to success including Obama |
Why did Michelle mention Obama in the last paragraph?
| A．To make the students know more about Obama. |
| B．To offer an example of overcoming difficulties. |
| C．To give advice on how to be a great man. |
| D．To talk about his failures. |

Do you want to be a successful person? Would you like to know how successful people usually think and what drives them? Here I am going to tell you the key to success that successful people share.
First of all, successful people never blame someone or something outside of themselves for their failure to move ahead. They realize that their future lies in their own hands. They understand that they can’t control things in life, such as nature, the past and other people. At the same time, they are well aware that they can control their own thoughts and actions. They take responsibility for their life.
Perhaps what most separates successful people from others is that they live life “on purpose” --- they are doing what they believe they are put here to do. In their opinion, having a purpose in their life is the most important element that enables them to deal with things around them. They hold the view that when they live their life “on purpose”, their main concern is to do the job right. They live what they do. People want to do business with them because of their commitment. To live their life “on purpose”, successful people find a cause they believe in and create a business around it.
Besides, they never give up easily. Once they have set up goals in their life, they are willing to do whatever it takes to achieve their goals. To achievers always bear in mind what they don’t have forever. Rather than see this as negative or depressing, they would use the knowledge to spur themselves on and go after what they want energetically and passionately.
So keep in mind what successful people always hold to be true so that you will have a clear idea of what you should do to be successful in life.According to the passage, to be successful, ______.
| A．you should set up a realistic goal |
| B．you should know your strengths and weaknesses |

It was Monday, Mrs. Smith’s dog was hungry, but there was not any meat in the house.
Considering that there was no better way, Mrs. Smith took a piece of paper, and wrote the following words on it: “Give my dog half a pound of meat.” Then she gave the paper to her dog and said gently: “Take this to the butcher（卖肉者）, and he’s going to give you your lunch today.”
Holding the piece of paper in its mouth, the dog ran to the butcher’s shop. It gave the paper to the butcher. The butcher read it carefully, recognized that it was really the lady’s handwriting and presently did as he was asked to. The dog was very happy, and ate the meat up immediately.
At midday, the dog came to the shop again. It gave the butcher a piece of paper again. After reading it, he gave it half a pound of meat once more.
The next day, the dog came again exactly at midday. And as usual, it brought a piece of paper in the mouth. This time, the butcher did not take a look at the paper, and gave the dog its meat, for he had thought of the dog as one of his customers.
However, the dog came again at four o’clock. And the same thing happened once again. To the butcher’s more surprise, it came for the third time at six o’clock, and brought with it a third piece of paper. The butcher felt a bit puzzled. He said to himself, “This is a small dog. Why does Mrs. Smith give it so much meat to eat today?”
Looking at the piece of paper, he found that there were not any words on it!When Mrs. Smith’s dog was hungry, what did she give to the dog?
A. some chicken
B. half a pound of meat
C. a hot dog
D a piece of paper with some words on itMrs. Smith treated her little dog quite __________.
| A．rudely | B．proudly |
| C．friendly | D．angrily |
From its experience, the dog found that __________.
| A．only the paper with Mrs. Smith’s words on it could bring it meat |
| B．a piece of paper could bring him half a pound of meat |
| C．the butcher would give the meat to it whenever he saw it |
| D．Mrs. Smith would pay for the meat it got from the butcher |

| A．the dog was clever enough to write on the paper |
| B．the butcher was told not to give any meat to the dog |
| C．the dog dared not go to the butcher’s any more |
