At a certain point in our lives our body systems will begin to weaken . It may become more difficult for us to see and hear. The slow change of aging causes our bodies to lose some of their ability to bounce back from disease and injury. In order to live longer , we have always tried to slow or stop this change that leads us toward the end of our lives.
Many factors decide our health . A good diet plays an important role. The amount and the type of exercise we get are another two factors. Our living condition is yet another. But scientists studying the aging problem want to know: Why do people grow old? They hope that by studying the aging medical science they may be able to make the length of life longer.
There is nothing to be afraid of as the old age comes. Many consider the later part of life to be the best time for living. Physical activity may become less, but often we get better understanding of the world and ourselves.
What we consider the old age now may only be middle-aged some day soon. Who knows ,with so many advances in medical science happening so quickly, life length may one day be measured in centuries ,rather than in years!
小题1:The underlined phrase “bounce back ”means “__________.”
| A．jump backward | B．run fast | C．prevent | D．recover |
| A．teach people how to eat properly |
| B．discover how important the exercise is to one’s health |
| C．study the ways to slow or stop the process of aging |

举一反三
Sometimes we treat people from other countries unfairly, because one person from that culture did something bad．Well, has your class ever been punished just because a few kids were causing trouble? Has your whole family ever been blamed for something your little sister did? It doesn’t seem fair, does it? It’s just equally unfair to blame a whole culture for what two or three people have done.
So here are some things that you can do to help yourself understand other cultures:
①Find common ground!
Just remember that even though some people look different on the outside, that doesn’t change how they are on the inside．They still have the exact same feelings!
②________________
Because someone from another culture has been mean to you, you decide to avoid everyone from that culture．Well think about it．Why are you blaming them for something they didn’t have anything to do with? Put yourself in their shoes．How would you feel? Putting yourself inside someone else’s head can be a very powerful way to understand WHY they are acting the way they are.
③Try to make friends with people from other cultures!
You could ask them about their culture, or what it is like in their country, if they can remember, or if they have ever lived there．Try foods from their culture, or ask them about words in their language．You might be surprised at how interesting other cultures can be! You can join great discussion groups, participate in projects, and have lots of fun doing new things.
④Be aware that you’ve judged other people
If you know what you have done, it helps to make things better．Pay attention to what you think about other people．It helps.
小题1:What is mainly discussed in this passage?
| A．Why there are differences between people |
| B．What to do to understand other cultures |
| C．How people feel when they meet people from other cultures |
| D．The differences between people from different cultures |
| A．Avoid everyone from that culture! |
| B．Put all responsibilities on others! |
| C．Consider oneself first! |
| D．Don’t blame all because of one! |
| A．feel proud of | B．express ideas of |
| C．praise and enjoy | D．pay attention to |
| A．join their discussion groups | B．try foods from their culture |
| C．avoid meeting them | D．find common ground |
But after a while I couldn’t ignore the high relationship between success and rising early．On those rare occasions where I did get up early, I noticed that my productivity was almost always higher．So I set out to become a habitual early riser．But whenever my alarm went off, my first thought was always to stop that noise and go back to sleep．Eventually some sleep research showed me that I was using the wrong strategy．
The most common wrong strategy is this: You assume that if you’re going to get up earlier, you’d better go to bed earlier．It sounds very reasonable, but will usually fail.
There are two main schools(流派) of thought on sleep patterns．One is that you should go to bed and get up at the same time every day．The second school says you should go to bed when you’re tired and get up when you naturally wake up．However, I have found both of them are wrong if you
care about productivity．If you sleep at set hours, you’ll sometimes go to bed when you aren’t sleepy enough．You’re wasting time lying in bed awake and not being asleep.If your sleep is based on what your body tells you, you’ll probably be sleeping more than you need．Also, your mornings may be less predictable if yo
u’re getting up at different times．The solution for me has been to combine both methods．I go to bed when I’m sleepy and get up with an alarm clock at a fixed time．So I always get up at the same time (in my case 5 am), but I go to bed at different times every night — sometimes at 9:30pm, and other times at midnight．Most of the time I go to bed between 10-11 pm．
However, going to bed only when I’m sleepy, and getting up at a fixed time every morning is my way．If you want to become an early riser, you can try your own.
小题1:According to the passage, the underlined phrase refers to ____.
| A．people who stay up until the next morning. |
| B．people who get up early in the morning. |
| C．people who feel sleepy in the morning. |
| D．people whose productivity is the highest in the morning. |
A．Because h e / she wanted to form the habit of going to bed early and getting up early. |
| B．Because he / she had found that his / her productivity was higher when he / she got up early. |
| C．Because he / she wanted to see which of the two main schools of thought on sleep patterns was right. |
D．Because he / she was told t he high relationship between success and rising early. |
| A．going to bed after midnight． |
| B．getting up early occasionally. |
| C．pressing off the alarm to go on sleeping. |
| D．asking scholars for advice on sleeping habits. |
| A．how to become an early riser． |
| B．how to have good sleep. |

The observation might help explain how all whales hear. The work might also help scientists understand how animals ar
e affected by underwater sonar (声呐). This sonar, used by some ships, sends out sound waves to locate underwater objects. The Cuvier’s beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to “see” the shape, size, and location of objects, even when they’re 1,000 meters under the sea, where it is totally dark.
To better understand how the whale hears, researchers from San Diego State University in California took X rays of two Cuvier’s beaked whales. The whales had died and washed up on the beach.
Ted Cranford and his colleagues used the images to make a computer model of a Cuvier’s beaked whale’s head. Then, they modeled the process of sound traveling through the head.
The researchers knew that some sounds get to the ears of a toothed whale through a structure (构造) called “the window for sound”. Found on the lower jaw, this structure is very thin on the outside and has a large pad (垫) of fat on the inside.
When the researchers used their computer model to work out how sound waves travel in the whale’s head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal’s jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal’s ears.
69. 小题1:Toothed whales look for food under the sea by ______.
| A．watching the shape and size of their objects | B．diving deep into the sea |
| C．sending and receiving sounds | D．making lots of noises |
| A．find out why they had died and washed up on the beach |
| B．make a computer model of a Cuvier’s beaked whale’s head |
| C．make sure that sound travels through the head |
| D．know more about the way the whale hears |
| A．A hole in the back of the jaw → the ears → the jaw → the throat. |
| B． The jaw → the throat → a hole in the back of the jaw → the ears. |
| C． The throat → the jaw → the ears → a hole in the back of the jaw. |
| D．The ears → the throat → a hole in the back of the jaw → the jaw. |
| A．The throat is important to the Cuvier’s beaked whale’s hearing. |
| B．Ships send out sound waves like a Cuvier’s beaked whale. |
| C．The ears are actually useless to the Cuvier’s beaked whale. |
| D．The researchers haven’t found how the whales hear. |
The key to reaching or staying at a healthy weight is regular exercise and good eating habits. Teens should get 60 minutes or more of physical activity a day. Note the word “activity”. As long as you’re getting your body moving, it doesn’t have to mean doing complicated exercises or going to the gym (体育馆) every day. All that matters is that each week you get the right balance of activity, including aerobic (有氧健身法的) strength building, and flexibility (柔韧性) exercise. Make exercise a habit by scheduling some every day.On days when you have soccer practice or an aerobics class, you may have no trouble exercising for an hour or more. But most of us are busy, and 60 minutes a day of activity seems like a lot of time. The good news is that it’s OK to divide it into shorter “exercise breaks” throughout the day. Just as you might have a healthy snack to stop yourself getting hungry, exercise snacks can keep energy level high. So get up 15 minutes earlier and do some yoga or other stretching (伸展) activity. Fast walk or jog (慢跑) for 15 minutes at lunch. Do the same thing after school or walk or bike home. Add to that taking the stairs, gym class, and walking between classes during the day, and you’ve probably reached your 60 minutes.Here are 5 simple ways to make an exercise lifestyle change:1. Start today. Go outside for a walk.2. Take the stairs instead of the elevator.3. Instead of driving, walk or bike to places like school or a friend’s house.4. Clean your room or wash the car.5. Limit your time watching TV, using the computer, or playing video games--and when you do play, try some games that get you moving.小题1: The underlined phrase “exercise snacks” in the second paragraph probably means ________.| A．food eaten before exercise | B．food eaten during exercise | C．shorter “exercise breaks” | D．a new kind of exercise |
小题2:Why should we have exercise snacks every day?A．Because they can stop us getting hungry | B．Because they can keep energy level high | C．Because they can include many kinds of sports | D．Because they are more likely to relate to our daily life |
小题3:Which of the following is NOT mentioned in the passage?| A．To go hiking on your holidays | B．To spend less time on computer games | C．To go to school on foot or by bike | D．To do some housework at home |
小题4:What will be most probably discussed in the following paragraph?| A．Losing weight | B．Good eating habits | C．Exercising your brain | D．Outdoors exercise |
小题5: What would be the best title for this passage?| A．Regular exercise | B．School exercise | C．Indoors exercise | D．Difficult exercises |
India’s National Family Health Survey shows that more than twenty percent of Indians living in cities are overweight or obese. And in the northwestern state of Punjab, that is true for almost forty percent of women.
Aradhna Tripathi is a business professional in New Delhi. She said, “ Eating is the most important thing in any Indian household and how you show your love and gratitude(感激) for a person is through the kind of food you serve him. And the kind of lifestyle we are leading is one of the reasons why we have the number of obese people increasing every day.
But Aradhna Tripathi says she has decided to lose weight. Her mother and grandmother are also diabetic(患糖尿病的). In fact, the International Diabetes Federation says India is now the diabetes capital of the world. Researchers say Indians store more body fat per kilogram than Europeans. That means obese Indians are even more at the risk of diabetes than other people.
Doctor Anoop Misra at Fortis Hospital in New Delhi says the risk of diabetes is crossing social and economic lines. Five years ago, he says, obesity and diabetes were limited to India’s richest people, but now things have changed.
But Doctor Misra is hopeful that the spread (蔓延，传播)of obesity can be slowed. And he says it must start in schools by giving all Indian children the same instruction on physical activity and diet.
The World Health Organization says China is also moving up in obesity rates. The estimate (估计) has reached about five percent countryside and as high as twenty percent in some cities.
小题1:What is this passage mainly about?
| A．Obesity has become a big killer in India. |
| B．Heart disease is troubling people in India. |
| C．People in India live a very unhealthy life. |
| D．Malnutrition remains a serious problem in India. |
| A．.the development of economy |
| B．the change of Indians’ lifestyle |
| C．Indians’ attitude （态度）towards eating |
| D．Indians’ attitude towards obesity. |
| A．Most wealthy people in India are overweight. |
| B．Five years ago, few people in India were overweight |
| C．Few poor people are diabetic for economic reasons. |
| D．Now even the poor in India suffer from obesity. |
