Different exercise types have different purposes and different benefits. One type of exercise may not accomplish all goals of being physically fit: a healthy heart, strong muscles and bones, and safety from injury. As a result, it is important to do enough types of exercise to have all the physical benefits. Here is a quick check sheet.
Aerobic Exercise: To have a strong and healthy heart, you need to do aerobic exercise. This means that you need to exercise yourself enough so that your heart rate, while exercising, is 65 percent to 85 percent of your maximum heart rate. If you don’t get your heart rate up within this level—you just aren’t working hard enough. Whatever you do, your heart rate needs to be 65 percent to 85 percent of your MHR for 20 to 30 minutes, at least 3 times a week. Typical types include:
* Running
* Walking (at least 4 to 4.5 mph)
* Swimming
* Bikingk3s5u
* Elliptical Training
* Yoga
Strength Training: To keep your muscles and bones strong, you need to do strength training. This comes in a variety of forms. Whatever you do, however, you need to train your muscles enough so that they are really tired by the end of each session. To see real benefits, make sure you are strength training 2 to 3 times a week for about 30 to 40 minutes. Typical types of strength training include:
* Weight Training
* Yoga
* Resistance Training
* Plyometrics
Flexibility Training: To keep your body flexible, reducing risk of injuries and pain in your joints and muscles, you need to do flexibility training. You should always aim to stretch every muscle after any exercise routine. Typical types of flexibility training include:
* Stretching
* Yoga
* Pilates
So next time you think that yoga 5 times a week will be enough, think about what it is really doing. Is it getting your heart rate up? Are you making up your strength? Are you keeping your muscles flexible?
If your purpose is to _______, you can choose swimming as your exercise form.

A．keep muscles and bones strong

B．build a strong and healthy heart

C．keep body flexible

D．reduce risk of injuries and pain in joints and muscles

After reading this passage, we know that ________.

A．Yoga is really better for people than running

B．The three kinds of training have links with one another

C．Flexibility training helps you build up your muscles

D．The more exercise you do, the better

Which of the following is closest in meaning to “session” in Paragraph 3?

A．meeting

B．gathering

C．term

第二节：阅读下列短文，从每题所给的A、B、C和D四个选项中选出最佳选项。（共15小题，每小题2分，满分30分）
Have you noticed that the majority of human beings seem to focus on the negative? Bad news is often seen in the newspapers, television shows and magazines, but good news are often overlooked.
I saw a woman I was not very familiar with. She is a beautiful woman; every time I see her, I am struck by the smile on her face that can light up a whole room. So at one time I walked up to her and said, “You know, you are like liquid sunshine! Every time I see you, you give me so much joy.” I was not quite prepared for her reaction. She was blown away. Her eyes seemed about to shed tears, and she said, “That is so sweet! That is the nicest thing anyone has ever said to me!” It was as if nobody had ever told her how beautiful her appearance was. I was extremely moved by the moment I had shared with this woman.
Why not take notice of the positive and spread a little sunshine? When you are looking for beauty, you will begin to see it more and more. When you discover it, don’t be afraid to appreciate it. Not only will it make them feel good, it will make you feel good as well. I truly believe the saying, “What goes around comes around.” When you show kindness and sincerity, you will receive it back. You may even discover — much to your surprise — that you become the friend of someone you would never have expected to get along with.
66. The woman had tears in her eyes because __________.
A. the man’s behavior was so rude
B. she was nervous about the man’s words
C. the man told her the fact she didn’t know
D. she was so excited at the man’s praise
67. Which of the following is closest in meaning to the underlined sentence in the third paragraph?
A. The wise appreciate one another.
B. Respect yourself, or no one else will respect you.

D. Everybody should learn to praise others.

A. Pay attention to the positive B. Everyone likes to be praised
C. Spread a little sunshine D. Each of us has good points

In ancient China tea was probably used as a relish(开胃小菜) and as a medicine. Tea was first brewed(煮泡) as a medicine around 2,700 BC in the western mountains of China. Tea was likely seen as healthy in part because it was made with boiled water, which is safer to drink in an area of polluted water.
Tea drinking, and commercial cultivation(种植)，spread during the Tang Dynasty, 618-907, especially after a Buddhist monk(佛教僧侣), wrote a book on the virtues of tea, Cha Ching. Tea gradually became one of the seven basic necessities of Chinese life (The others are fuel, rice, oil, salt, soy sauce, and vinegar.)
A Japanese Buddhist priest, Saicho, is believed to have introduced tea to Japan, when he returned from a visit to China in 805. In Japan tea drinking was considered medicinal, and became closely associated with Zen Buddhism(禅宗).
Tea drinking also spread to Korea and Southeast Asia, and was taken over the Silk Road to Central Asia, Russia, and the Middle East.
Dutch explorers became familiar with tea in the 1590s and were soon importing tea to Europe. In 1657 the British East India Company held the first public sale of tea in England, while that same year Thomas Garraway began offering tea at his London coffee house.
In 1662 tea received a big boost(推进) in England when the Portuguese Catherine of Braganza, married King Charles II and introduced tea drinking to the British court.
Gradually, the British fell in love with tea, and with the sugar that went in it. In 1665, less than 88 tons of sugar was imported to Great Britain. By 1700, it had increased to 10,000 tons of sugar. In 1768 the East India Company imported 10 million pounds of tea to Britain.
1. Tea has been used as a medicine in China for _________.
A. about 8,000 years      B. about 4,700 years
C. about 2,200 years      D. about 2,700 years
2. Tea began to spread as a popular drink in China because of _______.
A. the Silk Road              B. the basic necessities of Chinese life
C. a famous book about tea   D. its association with Zen Buddhism
3. According to the text, we can infer that Britain________.
A. first introduced tea to Europe
B. was the first country to trade with China for tea
C. was the first country to have learned about tea from China
D. may be the biggest imported country of tea in Europe even today
4. What is the text mainly about?
A. The history of tea             B. How tea was introduced to other countries
C. China is the home of tea   D. The importance of tea

Some fish form huge schools. Could fish set up schools and teach their children how to survive in the ocean? You may ask. No. Here the “schools” are not the places where you study. They are fish shoals (鱼群) that cover tens of kilometers. What causes hundreds of millions of fish to gather and move together is one of biology’s mysteries.
Darkness appears to be the first step to the creation of shoals, according to a study published in the March 27 journal Science. A team of researchers from the Massachusetts Institute of Technology (MIT) and five other institutions studied Atlantic herring (鲱鱼), which forms shoals on a fishing ground off Massachusetts. They used an underwater imaging technology and fish-finding sonar (声纳) to observe the herring over several days in autumn when they spawn (产卵).
They found that, as the sun set, fish in scattered (分散的) groups began swimming much closer to one another than they normally do. When the number of fish reached a certain point in an area, this set off a chain reaction of similar behavior that spread like a sound wave through the water.
The herring’s movement seemed to be started by sunset. The team didn’t record the breakup of these shoals, but a previous study suggested that as the sun rose, the shoals fell apart.
“When the light fades (逐渐消失), it’s safer for the fish to move away from the seabed,” says Nicholas Makris, a professor at MIT who led the research. “Once they have a certain number of other fish, they suddenly come together - forming a shoal covering tens of kilometers within tens of minutes.”
Herring form shoals to migrate during the autumn spawning season. Some shoals were 40 km across and 30 m from top to bottom. They formed in deep water and moved into more shallow waters to spawn.
Forming shoals helps protect them from predators (掠食者) by giving them simple strength in numbers. The ordered movement of the shoal means the fish can reach their spawning ground more quickly and more safely.
Scientists have never before gathered information on so many animals acting together. Understanding these herring shoals could lead to more ideas about what causes animals to move in schools, says Iain Couzin, a biologist at Princeton University, US.
1. Which school in the following expressions is used the same way as the underlined one in the first paragraph?
A. schools of thoughts B. school a horse C. a school of whales D. a medical school
2. Which of the following statements is true?
A. There are more large shoals of herring at night than in the daytime.
B. The research on Atlantic herring was conducted independently by the Massachusetts Institute of Technology.
C. The larger the shoal of herring is, the more slowly it moves.
D. Scientists have found out the reason why fish gather and move together in huge shoals.
3. According to the research, herring tend to get together except ______.
A.when there are predators around B. when they spawn C. when the sun sets D. when the sun rises
4. What seems to be the main reason for herring to gather and move together?
A. To avoid the darkness.
B. To keep other kinds of fish out of their spawning ground.
C. To spawn in the shallow waters.
D. To make themselves feel safe.

I was parked in front of the mall wiping off my car. Coming my way from across the parking lot was what society would consider a bum (乞丐). “I hope he doesn’t ask me for any money,” I thought.
He didn’t. He came and sat on the curb (路边) in front of the bus stop but he didn’t look like he could have enough money to even ride the bus.
After a few minutes he spoke,“That’s a very pretty car.” He was ragged (衣衫褴褛的) but he had an air of dignity.
I said “Thanks” and continued wiping off my car. He sat there quietly as I worked. “Do you need any help?” I asked.
He answered in three simple but profound words that I shall never forget.
“Don’t we all?” he said.
I was feeling high and mighty, successful and important, above a bum in the street, until those three words hit me like a shotgun.
Don’t we all?
I needed help. Maybe not for bus fare or a place to sleep, but I needed help. I reached in my wallet and gave him not only enough for bus fare, but enough to get a warm meal and shelter for the day.
Maybe the man was just a homeless stranger wandering the streets. Maybe he was more than that. Maybe he was sent by a power that is great and wise, to minister to a soul too comfortable with himself.
Don’t we all? Those three little words still ring true. No matter how much you have, no matter how much you have accomplished, you need help too. And you never know when you may see someone that appears to have it all. They are waiting for you to give them what they don’t have.
1. What was the writer doing when he met the homeless person?
A. Shopping.       B. Cleaning his car.       C. Admiring his car.      D. Parking his car.
2. What does the underlined phrase “high and mighty” mean?
A. Tall.   B. On top of the world.C. Strong and powerful. D. Filled with false pride.
3. Which of the following can best describe the writer’s feelings about himself after the encounter?
A. He felt a new sense of pride.                  B. Inspired and humble.
C. Great and wise.                            D. Successful and important.
4. What does the article tell us?
A. We should help those less fortunate than ourselves.
B. Helping a person indirectly is preferable to direct, obvious help.
C. All of us, at certain moments of our lives, need help from others and should offer help ourselves.
D. Money is all important in life.

As school starts again, there's so much more for an American parent to nag （唠叨）about, like homework，bedtime and lost hours on the Internet.
But in the age of digital childhood，Jacky Longwell, 45 , of McLean, Virginia, often text – messages what she once told her children by mouth: Be nice to your brother; walk the dog; remember your reading.
This is the world of the modern family, in which even reminding children to do something has become electronic.
There are changes in how parents nag and in what they nag about and in how often of their nagging.
With technology," you nag more, and you are a little bit more precise （其体的）with your nagging,” said Reginald Black, 46, of Woodbridge. Virginia.
For many young people electronic nagging is part of the experience of growing up.
Charles Flowers, 17, a senior at St. John’s College High School in Washington, says his mother reminds him about everything from laundry, being on time to baseball practice and mowing the lawn by text.
When she uses capitals he knows she’s serious: GET HOME!
Some say technology has made nagging less annoying. Jacky Longwell thinks texts are less emotional than spoken messages and less likely to be resisted by teenagers.
“It’s not as painful for them to hear it by text. It becomes grouped with the friendly communication.” she said. “They can’t hear the nagging.”
She thinks a good way to do it is to mix friendliness with nagging. A parent can always start by saying hello.
Not all parents like the new electronic nagging. Joyce Bouchard, 51, a mother of four in Fairfax, Virginia , texts her 14 - year - old son but says that for many things-chores, homework-the old - fashioned way works better. Nagging by text has risks. She notes: “I always think, if you’re texting them something and they’re with their friends, they are getting a big laugh out of it.”
