Air is a colorless,tasteless and invisible gas that is around us. An “empty” drinking glass and an “empty” room,in fact,are not really empty. Each is filled with air. When the glass is filled with water,the water pushes the air out of the glass.

Air,as gas,has no definite shape,but because it is matter,it takes up space and it has weight. It is easy to show that air is something that takes up space. Stuff a piece of dry cloth into the bottom of a glass so that it will not fall out when the glass is turned upside down. Push the upside-down glass,holding straight up and down,into a jar of water till the glass is completely covered. When the glass is taken out of the water,the cloth is still dry. The air inside the glass shows that it takes up space and keeps the water from coming in.

A. it's a mixture B. it's a kind of gas C. it is matter D. it is nothing

() 2. Since air is matter,it has .

Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

Born in September, 1987, Irene Curie was the first of the Curies’ two daughters. Along with nine other children whose parents were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.

Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities（设备） to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognized in the form of a Military’s Medal by the French government.
In 1918, Irene became her mother’s assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.

Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity（辐射能）. Irene Joliot-Curie died from leukemia on March 17, 1956.

1.Why was Irene Curie awarded a Military Medal?

A. Because she received a degree in mathematics.

C. Because she won the Nobel Prize with Frederic.

D. Because she worked as a helper to her mother.

2.Where did Irene Curie meet her husband Frederic Joliot?
A. At the Curie Institute.

B. At the University of Paris.
C. At a military hospital.

D. At the College of Sevigne.

3.When was the second child of Irene Curie and Frederic Joliot born?

A. In 1932. B. In 1927.

C. In 1897. D. In 1926.

Americans have developed an olive oil habit. Out to dinner recently, I saw a man dipping his white bread in olive oil and then pouring it all over his salad, saying, "Wow, this is so good for me!"

But is olive oil the healthiest fat? No, it's not. You might ask, doesn't it lower cholesterol(胆固醇)? Well, only when you substitute olive oil in equivalent amounts for butter or oils that are higher in saturated（饱和的）fat. Olive oil doesn't lower cholesterol; it just doesn't raise it as much.

You may be better off with canola（菜籽油） oil. The 1999 Lyon Diet Heart Study found that a Mediterranean diet significantly reduced heart attacks and premature deaths. Many people attributed this to eating a lot of olive oil. But it was increased consumption of canola oil that accounted for these improvements.

Also, study participants ate more whole-grain bread, vegetables, fish and fruit, and less meat. Butter and cream were replaced with man-made butter made from canola oil, which has more healthy omega-3 fatty acids than olive oil does.

Another study found that olive oil reduced blood flow by 31%. Canola oil and fish oil don't. (You want to increase blood flow to all body parts.)

I like the taste of olive oil, and I use it sometimes. It's a healthier fat than many others, but it's not nearly as healthy as canola oil -- or fish oil and flaxseed oil, for that matter, which also have lots of omega-3s. And a tablespoon of any oil has 126 calories. Think about that before you pour it on.

1.It can be inferred that in America ________.

A. most people prefer canola oil than olive oil

B. most people think olive oil is healthier than others

C. people use olive oil to help them lose weight

D. most people choose olive oil for its better taste

2.The author may advise people _______.

A. to choose canola oil instead of olive oil

B. to think over before choosing new products

C. to keep on eating olive oil to keep healthy

D. to consult the researchers before accepting a trend

3.According to the author, olive oil ________.

A. isn’t as health as most people think

B. can be used as a substitute for meat

C. can help increase the blood flow

D. contain less calories than other oils

4.A Mediterranean diet reduced heart attacks and premature deaths thanks to .

A. olive oil B. butter C. canola oil D. Bread

We all know that the cost of heating our homes will continue to be a significant burden on the family budget. Now millions of people are saving on their heating bills with the EP Portable Heater. With over one million satisfied customers around the world, the new EP heats better and faster, saves more on heating bills, and runs almost silently.

The EP has no exposed heating parts that can cause a fire. The outside of the EP only gets warm to the touch so that it will not burn children or pets.

The EP will not reduce oxygen in the room. With other heaters, you’ll notice that you get sleepy when the heat comes on because they are burning up oxygen.

The advanced EP also heats the room evenly, wall to wall and floor to ceiling. It comfortably covers an area of up to 350 square feet. Other heaters heat rooms unevenly with most of the heat concentrated to the center of the room. They only heat an area a few feet around the heater. With the EP, the temperature will not vary in any part of the room.

The EP comes with a 3-year warranty (保修) and a 60-day unconditional refund.

Now, we have a special offer for 10 days, during which you can enjoy a half price discount and a free delivery. If you order after that, we reserve the right to either accept or reject order requests at the discounted price.
