    On October 31st, 2009, Chinese famous scientist Qian Xuesen, died in Beijing when he was 98 years old. He is famous as “the country's father of space technology and king of rocketry”.

    Qian was born in 1911 in Hangzhou. He left for the United States after winning a scholarship to graduate school in 1936. He studied at the Massachusetts Institute of Technology and later at the California Institute of Technology.

    Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics（航空学) before returning to China in 1955.

    After he returned, Qian set up the first missile（导弹）and rocket research institute（学院) of China. The institute later helped start Chinese space program. He led the development of China's first nuclear-armed ballistic missile (弹道导弹) and worked on its first satellite.

    He retired in the year before Chinese manned space program was launched in 1992. But his research formed the basis（形成基础）for the Long March CZ -2F rocket that carried astronaut Yang Liwei into orbit in 2003.

    In August, 2009, Chinese Premier Wen Jiabao visited Qian and praised him for devoting his life to Chinese defense technologies. Qian told him, “I'm trying to live to be 100 years old”.

    People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe. In the late 1800s, the Turks made cigarettes popular.

    Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person's breathing muscles. Smokers usually take in small amounts that the body can quickly break down.

    Nicotine can make new smokers feel dizzy(头晕) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers' risk of heart disease and stroke.

    Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.

    Why is pink or purple a color for girls and blue or brown for boys?

    The answer depends largely on cultural values as well as personal experiences. To the Egyptians, green was a color that represented the hope and joy of spring, while for Muslims, it means heaven. Red is a symbol of good luck in many cultures. In China, children are given money in a red envelope to bring good fortune in the New Year. For many nations, blue is a symbol of protection and religious beliefs. Greek people often wear a blue necklace hoping to protect themselves against evils（灾祸）.

    People's choice of colors is also influenced by their bodies' reactions （反应）toward them. Green is said to be the most restful color. It has the ability to reduce pain and relax people both mentally and physically. People who work in green environment have been found to have fewer stomach aches.

    Red can cause a person's blood pressure to rise and increase people's appetites（食欲）. Many decorators will include different shades of red in the restaurant. Similarly, many commercial websites will have a red “Buy Now” button because red is a color that easily catches a person's eye.

    Blue is another calming color. Unlike red, blue can cause people to lose appetite. So if you want to eat less, some suggest that eating from blue plates can help.

    The next time you are deciding on what to wear or what color to decorate your room, think about the color carefully.

    Can you imagine a world without music？Studies show that public schools across the country are cutting back on music classes to save money. Worse, some schools have never had music classes to begin with. But without them, students' academic growth and emotional health could suffer. In fact, music classes are necessary for all students in schools.

    Recent studies by Brown University have shown that students who received music education classes were better in math and reading skills than those without music classes. Another study by The College Board found that students taking music and art classes got higher points. Students' academic success seems to depend on their taking part in music education.

    Music programs in public schools also help to add to a student's sense of pride and self-confidence. Teens today have too many learning tasks. Besides, they have family problems, self-confidence problems, relationship troubles, and choices about drugs and alcohol. All of these can stop academic success, but music education can help. A study by The Texas Commission on Drug and Alcohol Abuse found that students who took part in school music programs were less likely to turn to drugs. Music programs encourage students to work together to produce an excellent performance.

    Music crosses language, class, cultural and political boundaries (界限). Music allows students from different countries to connect. For example, at a school talent show, a new Japanese student played a piano duet (二重奏) with an American classmate. Although they could not communicate verbally (口头上), they were able to read the music in order to play the duet. Two students from different cultures worked as a team with self-confidence and common purpose through music.

    The gift of music is priceless. We need to be sure to have necessary music classes for all students. The world is losing its music, and putting music into schools is the first step to get it back.
