1.Sometimes they try to get out of a class to escape a teacher they don’t like. Here is some advice to solve this problem.

Ask yourself, “What can I learn from this teacher?” Even if you don’t worship (崇拜) his or her personality or lectures, dig deep until you find a subject in which he or she is very knowledgeable. Focus on that part of the teacher’s personality, and use him or her as a tool for learning. Not only will you gain more knowledge in that subject, but a closer relationship with your teacher may help you understand one another better. 2.

Talk to students who are doing well in the class and ask them for tips, tools, and a plan of action to get along with the teacher better. 3.

If you still can’t get along, make an appointment with the school guidance counselor (辅导员). He or she will offer many tips and suggestions for you to get out of difficult teacher relationships. 4. That means they can help you and your teachers get rid of the bad impression on each other.

5. Your parents can meet with your teacher and try to work it out.

Teachers are there for more than just homework, and they know about more than just their subject matter. They can help you learn how to function as an adult and a lifelong learner.

Undoubtedly, these will be a few teachers along the way who you will always remember and who might change your life forever.

A. If your relationship problems can’t be solved in school, then it’s time to tell your parents or guardians.

B. If you’re too shy to talk to another student, study his or her actions and behavior in the classroom and try to follow that lead.

C. Students don’t always get along well with their teachers.

D. There must be something good in every teacher for you to learn from.

Easy Ways to Keep Your Brain Sharp

Everyone is forgetful, but as we age, we start to feel like our brains are slowing down a bit—and that can be a very annoying thing. 1. Read on for some techniques worth trying.

1. 2.

People who regularly made plans and looked forward to upcoming events had a 50 percent reduced chance of Alzheimer's disease (早老性痴呆症), according to a recent study. 3.

Something as simple as setting a goal to have a weekly coffee date with a friend will do. There's evidence that people who have a purpose in life or who are working on long or short-term goals appear to do better. In other words, keep your brain looking forward.

2. Go for a walk.

Mildly raised glucose (葡萄糖) levels can harm the area of the brain that helps you form memories and physical activity can help get blood glucose down to normal levels. In fact, exercise produces chemicals that are good for your brain. 4.

3. Learn something new.

Take a Spanish class online, join a drawing club, or learn to play cards. A study found that mental stimulation (刺激) limits the weakening effects of aging on memory and the mind. But the best thing for your brain is when you learn something new and are physically active at the same time. 5. Or go dancing with your friends.

A. Focus on the future.

B. This can be especially harmful to the aged.

C. It should be something like learning gardening.

D. So take a few minutes each day to do some reading.

E. But don't worry if your schedule isn't filled with life-changing events.

F. Luckily, research shows there is a lot you can do to avoid those moments.

G. In other words, when you take care of your body, you take care of your brain.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。其中两项为多余选项

Before going outside in the morning, many of us check a window thermometer(温度计)for the temperature. This helps us decide what to wear. ____1.____. We want our food to be a certain coldness in the refrigerator. We want it a certain hotness in the oven. If we don’t feel well, we use a thermometer to see if we have a fever. We keep our rooms a certain warmth in the winter and a certain coolness in the summer.

Not all the thermometers use the same system to measure temperature. We use a system called the Fahrenheit scale. But most other countries use the Centigrade scale.

Both systems use the freezing and boiling points of water as their guide.___ 2.___ .

The most common kind of thermometer is made with mercury(水银)inside a clear glass tube. As mercury (or any other liquid ) becomes hot, it expands. As it gets colder, it contracts(收缩). That is why on hot days the mercury line is high in the glass tube.____ 3.___.

First. Take a clear glass juice bottle that has a cap ; fill the bottle with coloured water. Tap a hole in the center of the cap using a hammer and thick nail. Put the cap on the jar. Then stick a plastic straw(吸管) through the nail hole.

_____4.____.

Finally. Place a white card on the outside of the bottle and behind the straw. Now you can see the water lever easily.

_____5.____.

As the temperature goes down, the water will contract, and the lever in the straw will come down. Perhaps you will want to keep a record of the water lever in the straw each morning for a week.

A.We use and depend on thermometers to measure the temperature of many other things in our daily lives.

B.Thermometers measure temperature, by using materials that change in the same way when they are heated or cooled.

C.Now that you know this rule you can make a thermometer of your own that will work.

D.The water will rise in the straw. As the temperature of the air goes up, the water will expand and rise even higher.

E.They label these in different ways. On the Fahrenheit scale water freezes at 32 degrees and boils at 212 degrees. On the Celsius scale water freezes at 0 degrees and boils at 100degrees.

F.Take wax (you may use an old candle if you have one) and melt some of it right where the straw is struck into the cap to seal把..粘住) them together.

G.People use thermometers which are made by themselves when travelling around the world.

I am 26. I’m clear that I’m never going to catch up with Mother Teresa. But I want to do something to help people every single day like her.

Everybody thinks we just serve food and soda. The safety training is serious and stressful. Caring for 49 people in a business class in 90 minutes is not easy. I had a roommate who was a waitress; she just left a candle and a table cloth burning, and I used a fire extinguisher (灭火器) to put out the fire. If something goes bad at her job, she calls the police. But if something happens up in the air, it’s up to us.

I’m single and have no kids. I’ve flown every Christmas since 1995. If I fly, someone else can be with their kids. Christmas in an airport can be depressing, but it’s the little things that make a difference.

We’re not robots. It’s hard to put on a smile and just pretend everything is great when it isn’t. I’ve seen co-workers lose a family member the day before a trip and just pull themselves together (take control of their feelings and believe in a calm way). At the end of a 14-hour flight, it’s like, “It was really nice to help you, but I’m ready for you to get off the plane.” Those last 15 minutes can be the longest 15 minutes of your life. You can’t wait to turn off the flight attendant’s voice and get something to eat without anyone saying “Excuse me.”

Sometimes I go all day and never hear a “please” or a “thank you.” When you say thank you, it’s huge. It makes us feel like you actually see us as fellow humans. We’re up there together at a height of 30,000 feet, enjoying the miracle (奇迹) of the modern flight.

2.How did the author like her roommate’s job?

A. It was the same as hers B. It was more interesting than hers

C. It was easier than hers D. It was more serious than hers

3.Why does the author fly every Christmas?

A. Because she has nowhere to go.

B. Because she’s trying to be a helpful co-worker.

C. Because she owes her co-workers some favors.

D. Because she’d like to earn more money.

4.What does the author imply by saying the underlined sentence “We’re not robots”?

A. Flight attendants are not stronger than robots.

B. Flight attendants also experience emotions.

C. Flight attendants get tired while robots don’t.

D. Flight attendants need to rest now and then.

SAN FRANCISCO — Apple is cleaning up its manufacturing operations in China to reduce the air pollution caused by the factories that have assembled (装配) hundreds of millions of iPhones and iPads during the past eight years.

The world's most valuable company is working with its Chinese suppliers to eventually produce 2.2 gigawatts of solar power and other renewable energy.

The commitment announced Wednesday represents Apple's latest attempt to prevent the popularity of its devices and digital services from increasing the carbon emissions that are widely believed to change the Earth's climate.

Apple Inc. estimates (估计) 20 million tons of greenhouse gas pollution will be avoided as more of its suppliers rely on renewable energy between now and 2020. That's like having four million fewer cars on the road for a year.

Panels capable of generating (生产) about 200 megawatts of solar power will be financed by Apple in the northern, southern and eastern regions of China, where many of its suppliers are located. The company is teaming up with its Chinese suppliers to build the capacity for the remaining 2 gigawatts of renewable energy, which will be a mix of solar, wind and hydroelectric power.

Foxconn, which runs the factory where the most iPhones are assembled, is pledging to contribute 400 megawatts of solar power as part of the 2-gigawatt commitment. The solar panels to be built by 2018 in China's Henan Province are supposed to produce as much renewable energy as Foxconn's Zhengzhou factory consumes while making iPhones.

Apple has made protecting the environment a higher priority since Tim Cook replaced the late Steve Jobs as the company's CEO four years ago.

"Climate change is one of the great challenges of our time, and the time for action is now," Cook said in a statement. "The transition to a new green economy requires innovation, ambition and purpose."

Apple just completed projects in China that generate 40 megawatts of solar energy to cover the power required by its 24 stores and 19 offices in the country. All of Apple's data centers, offices and stores in the U.S. already have been running on renewable energy.

"When you look at all the air pollution in China, all the manufacturing that is done there has a lot to do with it, so this is a significant step in the right direction," said Gary Cook, a senior analyst for Greenpeace, a group devoted to protecting the environment.

Apple also has a financial motivation to help make China a better place to live. The greater China region is Apple's second biggest market behind the U.S. Tim Cook has made it clear that he wants the company to make even more progress as rising incomes enable more of China's population to buy smart phones and other gadgets.

Apple can easily afford to go green. The company had $203 billion in cash at the end of June. This story has been reflected to correct that Apple and its suppliers haven't set a timetable for producing the 2.2 gigawatts of renewable energy in China.

1.The commitment announced Wednesday shows that ______.

A. Apple wanted to change its public image eagerly

B. Apple wanted to contribute to protecting the environment

C. Apple wanted to cut down its expenses by using renewable energy

A. There will be four million fewer cars on the road for a year

B. 20 billion tons of greenhouse gas pollution will be avoided

C. Much of its greenhouse gas pollution will be avoided between now and 2020

D. China will become Apple's second biggest market behind the US

3.Which of the following statements is TRUE?

A. Apple has enough cash in store for switching to renewable energy supply.

B. The 2 gigawatts of renewable energy will be a mix of solar, wind and electric power.

C. Apple's data centers, offices and stores already have been running on renewable energy.

D. Apple will eventually produce 2.2 gigawatts of solar power and other renewable energy.

4.What is Gary Cook's attitude towards Apple's commitment?

A. Optimistic B. Supportive

C. Doubtful D. Indifferent
