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 | D．period |
The paragraph following this article may discuss_______.
| A．how to build up our strength |
| B．how to choose an exercise type |

The World Health Organization reports a number of people have died of the Ebola virus in central Africa during the last few months. Ebola, also known as Ebola hemorrhagic (出血) fever or Ebola viral disease, is a rare and deadly illness with high death rates in humans and primates. The natural source of Ebola virus remains unknown, although bats seem to be the most likely source.
The Ebola virus began spreading after victims were discovered in northeastern Gabon. So far, it is the third time Ebola has spread through Gabon since 1994. Health officials believe people moving across the border spread the disease from Gabon to Congo. Ebola is highly infectious and kills up to 80% of its victims. Researchers do not know the method with which the virus first appears in humans, but they believe it is through infected animals. The disease then spreads from person to person through blood and other body liquids.
Ebola victims treated early have the base chance of survival. Signs of Ebola include a high temperature, diarrhea, muscle pains and bleeding inside the body, in severe cases, victims experience chest pains and death. There is no known cure for the disease and no way yet to prevent it.
Scientists at the American National institutes of Health are working to develop a vaccine(疫苗) to prevent Ebola. Doctor Cary Nobel is leading the research effort at N-l-H testing center in the eastern state of Maryland. He says that during the past two years, the vaccine has been tested on small animals and monkeys for safety and effectiveness.
In the most recent study, four monkeys who had been given the vaccine were completely protected from a deadly injection of the Ebola virus. The study was described in November in Nature magazine. Doctor Nobel says the tests appear to have moved scientists one step closer to a vaccine for humans.Where does the Ebola virus come from?
| A．Bats. | B．Monkeys. | C．Infected humans. | D．Something unknown. |
When infected with Ebola virus, people may experience the following except ____.
A. heart attack B. a rise in temperature
C. chest pains D bleeding inside the bodyWhat can we learn from the passage?
| A．Once infected with the Ebola virus, people can never survive. |
| B．Half of the Ebola victims will lose their lives. |
| C．No cure has been found for the disease. |
| D．Scientists have succeeded in preventing Ebola. |
What is Doctor Nobel's attitude towards the tests?
| A．Discouraged. | B．Positive. | C．Doubtful. | D．Not mentioned. |
The modern world is full of useful objects that were invented by someone, from spoons and chopsticks in our kitchens to the Ipads in our handbags. Each invention is an example of the creative power of the human mind. Where do inventors get their inspirations(灵感)? The inspiration behind each of these inventions varies.
Take the shopping cart as an example. Sylvan Goldman was a grocery store owner. Like most businessmen, he wished that his customers would buy more so that he could make more money. He knew what if they could carry more goods easily as they were shopping, when his sales would go up. While thinking about the problem one night, he had an idea. Working with a local handyman named Fred Young, he designed the first shopping cart. Today, retailers who use shopping carts sell more goods and make more profits.
Nature has also inspired inventors throughout history. This is what happened to George de Mestral one day. While hunting with his dog in the Swiss Alps, he noticed how the burs(剌球) of certain plants stuck to his clothing and to his dog' s fur. After examining them under a microscope,
he found they had tiny hooks that could easily stick to the fibers of clothing or animal hide. For the next ten years, George de Mestral searched for the hest way to produce his idea. The result of his original inspiration was Velcro, which is used in many modem objects, including sportswear, shoes, automobiles, and even space suits.
These examples show us that there are at least two possible inspirations for human creativity in the world of inventions — profit and nature. No doubt, the future will continue to breathe new life into the economies of the world with fresh ideas and inventions. How many of their creations will be inspired by natural phenomena? The world's problems require creativity and we can expect best solutions from future generations.Why did sales go up in Sylvan Goldman's grocery store after he began providing shopping carts?
| A．Because grocery stores without shopping carts made less money. |
| B．Because he lowered the prices of his goods. |
| C．Because customers liked the shopping cart’s creative design. |
| D．Because customers were able to carry more items when shopping. |
According to the article, which invention shows how nature inspires us?
| A．The bur. | B．The shopping cart. | C．Velcro. | D．Spoon. |
Which of the following statements would the author most likely disagree with?
| A．The future does not promise many useful inventions. |
| B．There are many interesting inventions in the world today. |
| C．Companies often invent things out of profit. |
| D．Nature inspires creativity. |

Jacqueline Bouvier Kennedy Onassis was one of the most private women in the world, yet when she went to work as an editor in the last two decades of her life, she revealed（展现）herself as she did nowhere else.
After the death of her second husband, Greek shipping magnate（巨头）Aristotle Onassis, Jacqueline’s close friend and former White House social secretary Letitia Baldrige made a suggestion that she consider a career in publishing. After consideration, Jacqueline accepted it. Perhaps she hoped to find there some idea about how to live her own life. She became not less but more interested in reading. For the last 20 years of her life, Jacqueline worked as a publisher’s editor, first at Viking, then at Doubleday, pursuing（追求）a late-life career longer than her two marriages combined. During her time in publishing, she was responsible for managing and editing more than 100 successfully marketed books. Among the first books were In the Russian Style and Inventive Paris Clothes. She also succeeded in persuading TV hosts Bill Moyer’s and Jose Campbell to transform their popular television conversations into a book, The Power of Myth. The book went on to become an international best-seller. She dealt, too, with Michael Jackson as he prepared his autobiography（自传）, Moonwalk.
Jacqueline may have been hired for name and for her social relations, but she soon proved her worth. Her choices, suggestions and widespread social relations were of benefit both to the publishing firms and to Jacqueline herself. In the books she selected for publication, she built on a lifetime of spending time by herself as a reader and left a record of the growth of her mind.

| C．Jacqueline ended up as an editor rather as First Lady |
| D．Jacqueline’s role as First Lady was more brilliant than as an editor |
