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(設(shè)備) 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(輻射能). Irene Joliot-Curie died from leukemia on March 17, 1956.

1.Why was Irene Curie awarded a Military Medal?

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.

Madrid, capital of Spain, is a city with large numbers of historic sites resting in the shadows of modern skyscrapers.

This city of over 3, 23 million people, up from 2,88 million in 2000, is proud of Western Europe’s royal palace, considered by many to be Madrid’s most beautiful building. Inside the Royal Palace 2,800 rooms are decorated with museum-quality furniture and artwork.

The internationally loved Prado Museum is the largest and most impressive art gallery in Spain. Opened in 1819, it is filled with works of art that include the world’s most comprehensive collection of Spanish paintings.

Spain is famous for its delicious ham, and there’s no better place to try it than at Museo del Jamón, which has five branches around the city. Hanging from the ceiling of each branch are dozens of hams of different types and flavors. Taste them in the bar.

For a refreshing choice, relax beside the swimming pool on the roof of the Emperador Hotel. Enjoy delicious desserts and drinks while viewing the city, or take a dip in the cool water.

科目:高中英語(yǔ) 來(lái)源:2015-2016學(xué)年廣東佛山第一中學(xué)高一10月月考英語(yǔ)試卷(解析版) 題型:閱讀理解

People in the United States honor their parents with two special days:Mother’s Day, on the second Sunday in May, and Father’s Day, on the third Sunday in June. These days are set aside to show love and respect for parents. They raise their children and educate them to be responsible (有責(zé)任感的) citizens. They give love and care. These two days make us think about the changing roles of mothers and fathers. More mothers now work outside the home. More fathers must help with child care.

These two special days are celebrated in many different ways. On Mother’s Day people wear carnations. A red one symbolizes a living mother. A white one shows that the mother is dead. Many people attend religious services to honor parents. It is also a day when people whose parents are dead visit the cemetery (墓地).On these days families get together at home, as well as in restaurants. They often have outdoor barbecues for Father’s Day. These are days of fun and good feelings and memories.

Another tradition is to give cards and gifts. Children make them in school. Many people make their own presents. These are valued more than the ones bought in stores. It is not the value of the gift that is important, but it is “the thought that counts”. Greeting card stores, florists, candy makers, bakeries, telephone companies, and other stores do a lot of business during these holidays.

1.Which of the following is NOT a reason for children to show love and respect for parents?

A. Parents bring up children.

B. Parents give love and care to children.

C. Parents educate children to be good persons.

D. Parents pass away before children grow up.

2.What do you think “florists” do?

A. They sell flowers.

B. They make and sell bread.

C. They offer enough room for having family parties.

D. They sell special gifts for Mother’s Day and Father’s Day.

3.What do you know from the passage?

A. Mother’s Day and Father’s Day are both in May.

B. Fewer women worked outside the home in the past.

C. Not all the children respect their parents

D. Fathers are not as important as mothers at home.

4.On Mother’s Day and Father’s Day, ________.

A. people usually have family parties

B. everyone goes to visit the cemetery

C. children always go to parents’ home

D. hand-made cards are the most valuable gifts
