One night I received a Facebook message from Laura, a former classmate. “Hey Steve,” s he said, “I know you’ve always been an animal lover. I’ve just had a baby and I can’t keep my mini pig.”
Being fond of animals, I knew I wanted the pig. I just had to figure out how to make it happen.
I lived in a two-bedroom single-level house in Georgetw on, Ontario. It’s tough to bring a pig back to the house I share with two dogs, two cats, and my lifelong partner.
But I was not letting that pig go. So I told Laura I’d take the animal. When I got home with the pig, I hid her in the bedroom, and began to prepare a dinner for Alisha —her favourite bacon cheeseburgers. It’s better to make her happy before introducing the new member to her.
When I led her to the bedroom and showed her the surprise, Alisha stood in the doorway like a statue. It took her a few seconds to know what I had done. She complained about my unreasonable action. She insisted there was no more room in the house.
I knew I was wrong, but I hoped I could smooth things over. Soon enough, the lovely pig did the smoothing for me. Never had we felt such joy as she brought to us. We got her a name “Esther”.
Esther’s arrival changed our lives. A few weeks later, we decided to stop eating bacon. We figured it was our turn to try to change the world for other animals. A few months later, we moved to a farm where we cared for abandoned animals — so far, six rabbits, six goats, two sheep, one horse, three cows and three chickens.
24. Who does the underlined phrase “my lifelong partner” in Paragraph 2 refer to?
A. Laura.
B. Steve.
C. Alisha.
D. Esther.
25. Why did the author cook Alisha a meal?
A. To please her to accept the pig.
B. To make an apology to her.
C. To celebrate Esther’s arrival.
D. To show off his cooking skills.
26. What was Alisha’s reaction the moment she saw Esth er?
A. She burst into tears.
B. She showed interest in her.
C. She quarreled with Steve.
D. She was frozen for a while.
27. What is the best title for the text?
A. A Small Pig Making a Big Difference
B. An Abandoned Pig Finding a Warm Home
C. A Little Pig Bringing Happiness to a Family
D. A Lovely Pig Removing a Couple’s Disagreement
C
Fabien Cousteau was born with deep love for the ocean. His grandfather and his father were ocean explorers and documentary filmmakers. Fabien spent his early years on his grandfather's ships. Today, Fabien follows in his family's footsteps to protect the planet's endangered ocean life. With his vast knowledge and experience, he tries to strike a balance between environmental problems and market economies.
Fabien is well known for his study of sharks. During 2000-2002, he created a TV special called Attack of the Mystery Shark based on the shark attacks that occurred along the New Jersey shoreline in the summer of 1916. Then in 2003-2006, with the help of a large crew, Fabien created a shark submarine (潜艇) that enabled him to put himself inside the shark world, providing people with a rare view of the mysterious and often misunderstood creatures.
For the next four years (2006-2010), Fabien was part of a series called, Ocean Adventures, which offered a rare look into some of the most fantastic ocean species (物种) and environments.
In 2010, Fabien started Plant A Fish, a nonprofit project for children to help restore local water ecosystems by replanting key ocean species. Save the world, one fish at a time. The project is still in progress now and its final goal is to plant 1 billion “fish” worldwide.
From June 1 to July 2, 2014, Fabien and his team spent 31 days underwater to research how climate change and pollution are affecting the oceans. Fabien's Mission 31 broke new ground by going deeper, longer and further, exposing (显露) the world to the adventure and the mystique (神秘) of what lies beneath.
Fabien is currently working on a documentary film about the adventures of Mission 31, as well as building an Ocean Learning Center to provide children around the world with the opportunity to learn about oceans and engage with ocean explorers directly through social media.
28.What is Not Fabien’s job?
A. Ocean explorer
B. Documentary filmmaker
C. Environmentalist
D. Media manager
29. How is Paragraph 2 developed?
A. By providing facts.
B. By offering analyses.
C. By making comparisons.
D. By drawing conclusions.
30. We can learn from the text that ________.
A. Fabien's “Plant A Fish” project has already achieved its final goal
B. Fabien's Mission 31 broke the records of former ocean explorations
C. Fabien's TV special about sharks is based on his childhood experiences
D. It took Fabien four years to produce Ocean Adventures all on his own
31. In which part of a website can we read the text?
A. Modern Technology.
B. Space Exploration.
C. Outstanding Figures.
D. Fantastic Wildlife.

Over the years, cheerleading has taken two primary forms: game-time cheerleading and competitive cheerleading. Game-time cheerleaders’ main goal is to entertain the crowd and lead them with team cheers, which should not be considered a sport. However, competitive cheerleading is more than a form of entertainment. It is really a competitive sport.
Competitive cheerleading includes lots of physical activity. The majority of the teams require a certain level of tumbling (翻腾) ability. It’s a very common thing for gymnasts, so it’s easy for them to go into competitive cheerleading. Usually these cheerleaders integrate lots of their gymnastics experience including their jumps, tumbling, and overall energy. They also perform lifts and throws. This is where the “fliers” are thrown in the air, held by “bases” in different positions that require strength and working with other teammates.
Competitive cheerleading is also an activity that is governed by rules under which a winner can be declared. It is awarded points for technique, creativity and sharpness. Usually the more difficult the action is, the better the score is. That’s why cheerleaders are trying to experience great difficulty in their performance.
Besides, there is also a strict rule of time. The whole performance has to be completed in less than three minutes and fifteen seconds, during which the cheerleaders are required to stay within a certain area. Any performance beyond the limit of time is invalid.
Another reason for the fact that competitive cheerleading is one of the hardest sports is that it has more reported injuries. According to some research, competitive cheerleading is the number one cause of serious sports injuries to women. Emergency room visits for it are five times the number than for any other sport, partially because cheerleaders don’t use protective equipment. Smiling cheerleaders are thrown into the air and move down into the arms of the teammates, which may easily cause injuries. Generally, these injuries affect all areas of the body, including wrists, shoulders, ankles, head, and neck.
There can be no doubt that competitive cheerleading is a sport with professional skills. Hopefully, it will appear in the Olympics since cheerleaders are just as athletic and physically fit as those involved in the more accepted sports. It should be noted that it is a team sport and even the smallest mistake made by one teammate can bring the score of the entire team down. So without working together to achieve the goal, first place is out of reach.
32. What is the main purpose of competitive cheerleading?
A. To compare skills of participants.
B. To make the audience feel amused.
C. To attract more people to watch events.
D. To cheer up the competitors on the court.
33. The underlined word “integrate” in Paragraph 2 probably means “______”.
A. examine
B. combine
C. identify
D. replace
34. We can learn from the passage that competitive cheerleading ______.
A. lacks necessary guidelines to follow
B. enjoys greater popularity than other sports
C. requires more designed actions than gymnastics
D. has a relatively high rate of damage to the body
35. Which of the following shows the structure of the passage?
I: Introduction P: Point Sp: Sub-point (次要点) C: Conclusion
A B C D

Sometimes it can be hard to recognize a true friend, one who is loyal(忠诚的)and one who is worth keeping by your side. The suggestions provided in this article will help to guide you in working out which friends are likely to be true.
Be able to trust your friends. You should be able to trust true friends and they should return this trust. Your friends tell you secrets that no one else knows. Let you share secrets. Ask you for advice.36.__________ However, if your friends hide things from you and act secretive, this could be a sign that they do not trust you, but it could also mean your friends keep to themselves or don’t like to reveal too much about themselves.
Consider comfort. How comfortable do your friends feel when they are around you? Watch them, are they being themselves or are they timid （胆怯的）around you? 37.__________True friendships can take
a while to develop, but if your friends are true, they should feel comfortable around you.
38.__________This is not meant in a romantic way, but consider whether your friends are comfortable with the touch. If your friends are fine with hugging you, leaning on you, resting their heads on your shoulder and so forth, then you can judge they love you.
Think about loyalty. True friends are always there for one another. If you are in need of a helping hand, your true friends should be there to offer it to you. 39.__________You can trust friends with anything, knowing that they will be loyal and will not let your secrets out.
Look at how you fight. Nearly all best friends fight; so if you and your friend have a little dispute（争论）, don't sweat it! 40.__________. They will not tell each ot her’s secrets and they still care about each other.
A. Consider the touch barrier.
B. Consider how you insult each other.
C. They should know that you are not serious.
D. These are sure signs that your friends trust you.
E. Are they acting fake—perhaps hiding an insecurity?
F. True friends should not get one another into trouble.
G. True friends will remain faithful and find their way through a fight.

54 doing that the first time Mom told me about one of her 55 who had died, but I’m sure I did n’t. I can’t imagine what it’s like to spend all day taking care of other people’s 56 children, some of whom are not going to 57 it, and then come home to find that your own kids are acting like that. We were just like 58 brats （顽童）then. I suppose she could have found our guilty weak spots to make us 59 , but she never did. I think I’d better 60 her for that.

Europe was very beautiful, but his holiday wasn’t very nicely. He visited several countries, and was in each of the countries for only three days. He visited a good many places of interest, but was always in hurry. Though he returned from Europe, he was very tired. So I suggest that you spent your holiday in a different way. We had better travel with a friend to one country and to visit only one city at a time. You’ll be able to have a good time.
Yours sincerely,
John

七、写作
As is vividly shown in the picture, a tiny man living in the city is standing there wearing a mask, terrified by the heavy smog, which looks like a huge frightening monster.
What the picture mirrors is clearly heavy smog and severe air pollution. Confronted with potential risks of sickness, people are always forced to wear masks in order to avoid breathing poisonous air. With smog getting increasingly serious, environmental protection has become an urgent issue for human beings. As a saying goes, great things may be done by mass effort. For one thing, our government should develop more green and energy saving ways to lower the emission of polluted air. For another, every single, person should raise their awareness of environmental protection and use more public transport. Only if we spare no effort to protect our environment, can we enjoy a greener and better life.
