    We’re surrounded by chemistry in everyday life. Sometimes it is easy to see, like when your science teacher does a big experiment in class. At other times, it can be pretty hard to see everyday chemistry at work, but nearly everything you touch or use has some element of chemistry in it.
    Something as simple as toothpaste contains at least three chemicals, if not more. It is the mixture of them and its chemical reaction that keeps your teeth clean. Other things you use every day are created by chemistry, such as hair products, shampoo and soap. Adding detergent (洗涤剂) to water involves chemistry. Without chemistry, we would never have known that we need soap to get the oil out of clothes or skin. Chemistry not only helps us make products for use, but it also helps us understand the world around us. Chemistry helps us understand what the ozone layer (臭氧层) is and how it protects us. Chemistry also gives us sunscreen to protect us from the sun. Thanks to chemistry, we know bleach (漂白剂) can’t be mixed with vinegar(醋), because it can produce poisonous gas.Without chemistry, we wouldn’t have fireworks displays on important days.
    Chemistry plays a big role in food preparation. Cooking food causes it to go through a chemical change. That is why cooked food often tastes different from raw food. Baking is a great example of chemistry. Too much or too little of any ingredient（成分，尤指烹饪） makes a difference to the result of baking, for example, the dough (面团) won’t rise or the cake will be flat.
    Chemistry isn’t something that just lives in a lab; it’s something that you meet hundreds of times every day. Knowing how chemistry works will give you a greater understanding of the science behind some of the simplest-looking things.

    科目：高中英语 来源：浙江省模拟题 题型：阅读理解

    阅读理解。
         A winner of the 2011 L'Oreal-UNESCO For Women in Science Awards, Professor Vivian
    Wing-wah Yam says she could not have done it without the backing of her family.
         The road to scientific discovery is tougher for women than for men and Professor Vivian Wing-wah
    Yam says she couldn't have succeeded without such a supportive family. The 47-year-old from Hong
    Kong University was one of five women scientists, from each continent, to receive the 2011
    L'Oreal-UNESCO For Women in Science Awards at a ceremony on March 3, at UNESCO
    Headquarters in Paris. It is the 13th edition of the award since 1998.
         Yam's long and fruitful research on solving the energy problem won her the prize for Asia and the
    Pacific. There are several renewable and sustainable(可持续的) energy solutions, like solar power,
    which could provide an unlimited source of energy. Some problems must be resolved, however, such as
    the low efficiency of solar cells and their high supply costs. Yam and her colleagues hope to overcome
    these problems by developing and testing new photoactive(光敏的) materials.
         She became the third Chinese women scientist honored with the so-called "woman's Nobel Prize"
    award, after Professor Li Fanghua from the Chinese Academy of Sciences in 2003, and Professor Ye
    Ruyu from Hong Kong University of Science and Technology in 2004.
         "People think chemists are bad guys, but we are the good guys," Yam said in a humorous aside
    before explaining her research project on photoactive materials in an earlier speech at L'Institut de
    France. For Yam, chemistry is science, but also an art. Amazed by the universe, nature and color in her
    childhood, Yam decided on a career in chemistry. "One of the beauties of chemistry is the ability to
    create new molecules and chemical species. I have always associated chemists with artists, creating new
    things with innovative(革新的) ideas," Yam said.
         As a mother of two daughters, 12 and 14, Yam said she is lucky to have been supported by her
    family. She was inspired as a child by her father, a professor in the Civil Engineering Faculty at Hong
    Kong University. Yam added her husband, Mak Shingtat, a PhD in chemistry, who accompanied Yam
    to the awards ceremony, was also fully supportive of her work. "I can't imagine how my career could
    move on without his understanding and support," she said. "I often stay late at night in the laboratory. He
    always waits for me outside."
         Yam received her bachelor and PhD degrees from the University of Hong Kong (HKU). She taught
    at City Polytechnic of Hong Kong before joining HKU as a faculty member, and headed the chemistry
    department for two terms from 2000 to 2005. At 38, she was the youngest member elected to the
    Chinese Academy of Sciences. She is also a Fellow of TWAS, the Academy of Sciences for the
    Developing World, and was awarded the State Natural Science Award and the Royal Society of
    Chemistry (RSC) Centenary Medal. 2011 is the 100th anniversary of Marie Curie's second Nobel Prize,
    coinciding (一致的)with the International Year of Chemistry. Today, Curie is still a role model for women
    in science.
         Although the participation of women in science, is promoted by UNESCO, notably through
    L'Oreal-UNESCO, there are still too few women doing high-level science, says UNESCO
    Director-General Irina Bokova. The latest UNESCO report shows less than 40 percent of countries
    provide girls and boys equal access to education.
         Each year, the L'Oreal-UNESCO For Women in Science Award recognizes 15 young women
    from all over the world, especially developing countries, to encourage and finance their studies. More
    than 200 young women scientists are currently supported. "I do not think there is a difference between
    men and women in terms of their intellectual abilities and research capabilities (能力)," Yam said. "As
    long as one has the passion, dedication and determination to pursue research wholeheartedly, one can
    excel regardless of one's gender or background."
        Yam said some young women, who require stability and security, often have to give up their research
    because of family pressures. "The only way for women to succeed in science is to get the mental and
    material support from family and society. There is a day-care center at my university, and my husband
    and mother-in-law help a lot with the housework, so I am able to spend my time on research," she said.
    "I have two young daughters, and it is too early to tell whether or not they want to pursue careers in
    science. But, I will encourage them to always defend their ideas. To remain determined, and to never be
    afraid of failure - this is the advice that they will need to succeed in realizing their dreams."
         Yam also acknowledged her colleague's support, at the awards ceremony. "This (award) not only
    recognizes me, but my colleagues and students and my country, China."

    A. an award for the developing world
    B. equal to Women's Nobel Prize
    C. held for more than 14 times

    B. She was amazed by the universe, nature and color in her childhood.
    C. She wanted to find the beauties of chemistry.
    D. She was encouraged by her supportive family.
    3. What's Yam's view on men and women?         .

    B. Their passion, dedication and determination are the same.
    C. Women require stability and security.
    D. Women can't get the mental and material support from family and society.

    A. her fruitful research on solving the environmental problem
