Dazzling (眼花缭乱) with their bright colors and eye — catching displays, fireworks light up our night skies during the holidays. However, these crowd -pleasers can have some damaging side effects. Once a firework is set off, it only takes a couple of seconds before smoke, dust and harmful chemicals are let out into the atmosphere. The loud booming noises are caused by gunpowder. While the sounds may excite some people, they can be frightening to domestic and wild animals — as well as some humans.
The pretty colors you see are a result of more chemicals. Barium, added to make green, is known for its poisonous and radioactive qualities. Blue comes from copper compounds. Cadmium, lithium and lead — all found in fireworks — have been linked to diseases, such as allergies and skin rashes in both humans and animals. Acid rain has been linked to gases given off by fireworks, which sometimes go beyond the toxin (毒素) limits of the United States Clean Air Act.
Once all those chemicals come back down to the ground, they can cause problems too. Debris (碎片) from the fireworks falls to the ground, where animals can bum their paws or noses on piping hot pieces. Humans also are at risk of stepping on or picking up something sharp or hot. Meanwhile, debris that finds its way into waterways can damage animal habitats and water supply sources. Instead of setting off fireworks, try to come up with some new ways for fun. Here are some ideas to get you started:
Sky lanterns — a tradition that originated long ago in the most-populated Asian country.
Party crackers — a favorite in the United Kingdom — give you noise and surprises without the mess of fireworks. You can make your own or buy eco-friendly crackers.
Want noise excitement with less volume? Consider a fireworks sound recording beforehand or break out the party horns (号角) and blow up a storm!
1.The advantages of fireworks can be seen below EXCEPT that _________.
A.the special sounds of fireworks excite people
B.the pretty and bright colors add to the beauty of night skies

Astronomy is the oldest science known to man.Thousands of years ago man looked at the stars and wondered about the heavens.But man was limited by what he could see with his eyes alone.
The Greeks studied astronomy over 2,000 years ago.They could see the size,color,and brightness of stars.They could see their places in the sky.They watched the stars move as the seasons changed.But the Greeks had no tools to help them study the starry heavens.
Each new tool added to the files of astronomy;it helped man reach out into space.Until there were telescopes(望远镜),man knew little about the moon.They did not know that the planet called Saturn(土星) has rings around it.Their sight was so limited that they could not see all the planets.In the early 1700s,people thought there were only six planets.
Before the spectroscope(分光镜),man did not know what kind of gases are in the sun or other stars.Without the radio telescope(电波望远镜)we did not know that radio noises come from far out in space.
Today,astronomy is a growing science.We have learned more in the last fifty years than in the whole history of astronomy.

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 (象征) 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.

With their furry round heads and big black eyes, Zhongzhong and Huahua look just the same as any other monkey. But they happen to be the world’s first cloned (克隆的) monkeys.
Years ago, scientists used cloning techniques to produce Dolly, the world’s first cloned mammal (哺乳动物).They now used the same technique to produce the monkeys in China.
In animal cloning, animals are produced in a lab by using DNA that is taken from the cells (细胞) of a naturally-born animal. To clone Zhongzhong and Huahua, scientists from the Chinese Academy of Sciences (CAS.中国科学院) first removed the nucleus (细胞核) from a monkey’s egg cell (卵细胞). They then put another nucleus taken from the monkey’s body cells into the egg cell. The newly-formed egg was put into the womb (子宫) of a female monkey. Finally, Zhongzhong and Huahua were born.
The cloning process is hard, especially removing nucleus. It needs to be done in a fast and precise (精确的) way. The faster you do it, the less damage is done to the egg, according to CAS. Scientist Liu Zhen spent three years practicing removing the nucleus.
Unlike common monkeys, cloned monkeys have the same DNA as each other. When doing experiments on them, scientists can easily know that certain results are caused by different treatments, rather than different genes.
According to Sun Qiang from CAS, most drug trials (药物试验) are done on lab mice. However, drugs that work on mice might not work on humans. The two species are very different.
“Monkeys and humans are much closely related and testing on monkeys is supposed to be as effective (有效的) as testing on humans,” Sun added.
1.Zhongzhong and Huahua are ______.
A. naturally-born monkeys
B. the world’s first cloned mammals
C. the world’s first cloned monkeys
D. twin sheep that were born by Dolly
2.What do we know about the two monkeys?
A. They look different from other monkeys.
B. They have the same DNA.
C. Their body cells don’t have any nucleus.
D. They can live for only three years.
3.What can we learn from Paragraph 4?
A. Removing the nucleus is difficult.
B. The cloning process is very safe.
C. It took three years to remove the nucleus.
D. It is impossible to clone other animals.
4.Why do scientists want to do drug tests on monkeys?
A. Because it’s easier to use them for tests.
B. Because there are not enough mice.
C. Because drugs work well on monkeys.
D. Because monkeys are similar to humans.
