Mr. Whitcomb Judson was a really clever man. He invented a special train that was pushed along by air and in 1893 he invented something like a zip(拉链) that could be used to open and close clothes. It could be used on men’s trousers and on ladies’ dresses. He did not call his invention a ‘zip’ but everybody says that he was the ‘Father of the Zip’. Mr. Judson tried to sell his invention but no one wanted it because it did not work very well. A Canadian changed Mr. Judson’s invention and made it better. He made a zip that worked very well in 1913.This is the same zip we use today.Mr. Whitcomb Judson was a _____ man.

When the Audet family turns on the lights at Blue Farm, they are using electricity that comes from cows—cow manure (粪肥), to be specific.
Cows produce a lot of wastes. One cow can create 30 gallons of wastes each day. Now imagine the output of over 1,000 cows at Blue Farm. That’s really a big amount.
When farmers clean their barns, they put the wastes in a big heap, and spread some of them on their fields for fertilizer(肥料). But now places like Blue Spruce Farm have a new way of using cow wastes. They use them to produce electricity.
Here’s how it works: A big machine moves back and forth cleaning the barn floor. “The cows aren’t bothered,” says Marie Audet. “They are animals of habit; they get used to it, and just lift one foot and then another to let it go by.”
The machine pushes the manure into a big 600-gallon tank like a small swimming pool. The tank is called a digester (化粪池) because what happens there is just like what happens inside a cow: Bacteria(细菌) get to work and continue to digest the manure.
Methane gas (甲烷、沼气)in the atmosphere is known as a “greenhouse” gas because it keeps heat just like a greenhouse does, causing our planet to warm up. That’s an environmental concern. But the digester has a good result. Its gas is kept and used to power electric generators (发电机).
At Blue Farm, the generators make enough electricity to power 400 homes. The Audet family sells the extra electricity they can’t use themselves.We learn from the text that the Audet family is using cow wastes to ______.
| A．make electricity | B．produce fertilizer | C．build their farm | D．feed the cows |
How are the cow wastes collected into the digester at Blue Farm?
| A．Marie Audet does the work | B．The job is done by machine |
| C．The cows lift the cow wastes | D．Bacteria get to work on them |
According to the passage, which of the following is changed into electricity?
| A．The power of moving water. | B．The heat of burning coal. |
| C．The power of sunlight. | D．The heat of the methane gas |
The new way of using cow wastes at Blue Farm might be best described as ______.
| A．reducing | B．saving | C．recycling | D．changing |
What is the main purpose for writing the passage?
| A．To introduce a new way of making electricity | B．To explain how a new energy works better |
| C．To show a new rebuilding plan for a big farm | D．To explain the reasons for green house effect |
When I was a kid in Minnesota, watermelon was expensive. One of my father’s friends, Bernie, was a rich businessman, who owned a large store in St. Paul.
Every summer, when the first watermelons arrived, Bernie would call. Dad and I would go to Bernie’s place. We’ d sit on the edge of the dock（码头）, feet dangling（摇晃）, and got ready for a big meal.
Bernie would take his knife, cut our first watermelon, hand us both a big piece and sit down next to us. Then we’d bury our faces in watermelon, eating only the heart—the reddest, juiciest, firmest, sweetest, most seed-free part—and throw away the rest.
Bernie was my father’s idea of a rich man. I always thought it was because he was such a successful businessman. Years later, I realized that it was not Bernie’s wealth itself but his way of dealing with it that my father liked. Bernie knew how to stop working, get together with friends and eat only the heart of the watermelon.
What I learned from Bernie is that being rich is a state of mind. Some of us, no matter how much money we have, will never be free enough to eat only the heart of the watermelon. If you don’t take the time to dangle your feet over the dock and enjoy life’s small pleasure, your work is probably hurting your life.
For many years, I forgot that lesson I’d learned as a kid on the loading dock. I was too busy making all the money I could.
Well, I’ve relearned it. I hope I have time left to enjoy the success of others and to take pleasure in the day. That’s the heart of the watermelon. I have learned again to throw the rest away. We learned from the second paragraph that the writer and his father were feeling ______.
| A．relaxed | B．worried | C．hungry | D．proud |
How did the writer and his father eat the watermelon?
| A．They ate it in a polite way. | B．They only ate its best part. |
| C．They ate every part of it. | D．They shared only one piece. |
In the eyes of the writer’s father, Bernie ______.
| A．was just a rich businessman | B．worked hard all the time |
| C．lived a rich but healthy life | D．knew how to make money |
The underlined part “the heart of the watermelon” in the last paragraph refers to ______.
| A．the best part of the watermelon | B．the writer’s busy life |
| C．the writer’s decision of making money | D．the writer’s hope of enjoying life |
It can be learned from the passage that ______.
| A．one has to work hard to reach his goal | B．a friend in need is a friend in deed |
| C．watermelon is the healthiest fruit | D．one should keep work-life balance |
Do you know that it is your own immune system working against the virus that makes you uncomfortable when getting a cold, but not the virus itself? So when you have got a strong immune system and the virus is strong enough too, you will possibly get terrible cold symptoms( 症状) ?
Vitamin C won’t stop a cold
It is claimed that Vitamin C helps by increasing white blood cells. However, many tests have shown that it does not prevent colds. At best, it only slightly reduces the rime of symptoms.
Staying indoors won’t protect you
One of the most likely sources of cold viruses is your computer mouse or desk. A study of the cold virus in offices found that 47% of desktops, 46% of computer mice and 45% of telephones had cold viruses on them.
Wrapping up warm won’t protect you
Colds are more common in autumn and winter. That’s because the cool, wet and cold weather drives people indoors, where viruses may more easily jump from one person to another. And the distinct peak in colds(感冒高峰) is in September and early January, which is likely due to the return of students to schools and colleges after the summer and winter vacation.

The widespread number of food scandals ( 丑闻) in China is making many people pause before they put their chopsticks in their mouth. They are wondering if the food they are eating is clean, healthy and nutritious or does it contain something harmful that will cause disease?
Most of the food we eat today is processed food( 加工食品). That means the foods we buy in stores and supermarkets, especially packaged foods, are prepared in factories.

In 1961, a man found a strange cat on his farm in Scotland. The cat’s ears were folded, bent forward, on its head. In fact, this was a new kind of cat. People named it the "Scottish Fold(苏格兰折耳猫)".
