Bedazzling (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 burn 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. debris from fireworks can even find its way into water
C. the pretty and bright colors add to the beauty of night skies
D. fireworks are enjoyed as one of the crowd-pleasers

A. Copper compounds are needed to make green in fireworks.

A. Gunpowder in fireworks makes loud booming noises.
B. It must be Indians who first started to hang sky lanterns.

高三英语单项填空中等难度题查看答案及解析
People have been growing chrysanthemums(菊花)for more than 2,000 years. Mums make bright and colorful gardens. People in China and other Asian cultures make tea with the flowers.
One basic kind of mum is the garden mum. The other basic kind is the florist mum. The garden mum is better able to handle different growing conditions.
There are many varieties of mums. The decorative mum is often seen in gardens. Another popular type, the quill mum, has long, straight petals(花瓣)like a tube or needle.
Chrysanthemum blooms can be white, yellow, gold, red or other colors. The plants often grow one meter high.
The soil for chrysanthemums should be kept moist but well drained so it does not get too wet.
Newly-planted mums should be watered two or three times a week, depending on conditions. Plants established in the ground may do well just with normal rainfall.
Mums grow best in full sunshine. They produce colorful blooms when days get shorter and nights get longer. The life cycle of the plant depends on the amount of daylight. This is why experts advise against placing mums near night lights or street lights. The light may interfere with their normal growth cycle. The plants may develop buds too soon.
In climates where temperatures fall below freezing, plant mums at least six weeks before the first frost. That way, the plants will be well established for cold weather.
Some gardeners say the most beautiful presentation comes from planting mums close together. But be sure to leave enough space to let air flow between the plants. If not, there may be a greater chance of disease.
To get more blooms, gardeners pinch(掐)back the branches when new growth has reached fifteen centimeters. Squeeze about five to seven centimeters off each branch. Pinch it again when a branch grows another twelve to fifteen centimeters. Stop the pinching about one hundred days before you want the plants to bloom.
1. What has a great effect on the life cycle of the mum?
A. The conditions of the soil. B. The amount of daylight.
C. The amount of rainfall. D. Cold weather.
2.Why do gardeners pinch back the branches when new growth reaches certain length?
A. To make mums grow thick. B. To get more blooms.
C. To prevent mums from falling ill. D. To let air flow between the plants.
3. Which of the following is true according to the passage?
A. Growing mums has a very long history and all the people in the world like making tea with mums.
B. Mums can grow one meter high and the closer they are planted, the higher they grow.
C. Though planting mums close together can make them look more beautiful, enough space should be left.
D. The petals of mums are long and straight and the more water mums get, the more quickly they grow.

Today it is common to see people who walk about with colored wires hanging from their ears wherever they go. They move about in their personal bubbles, sometimes unaware of what’s happening around them. 1. Outside life is shut out. So are you one of “them”?
For me, walking around in my own personal bubble is perfect. 2. What’s even better, wearing earphones seems to give a signal to people which says, “I’m not available for chatting at the moment!”
Suppose, you’re at work and about to make an incredible breakthrough, but a colleague suddenly turns up. At this precise moment, the slightest disturbance would break your concentration. 3. Once again, those wires hanging from your ears would be sure to give that “Go away!” signal.
4.It’s probably part of the growing up stage when they just want to ignore their whole family. While their mothers give them lectures about why they should do their homework, they can just turn up the volume on their MP3 player, smile, and say “Yes, Mum.” Problem solved.
Pretty soon, not only will we have pretty colored wires hanging from our ears—but also our brains will be directly plugged into some new high-tech instruments. We’ll be in a virtual(虚拟的) world, communicating with everyone else, or choosing not to, as we like. In this world, we will all be permanently plugged in. 5. And they are changing our social habits along the way.
In the end, there is a thin line between using technology as a tool for making life better and being a slave to it! It’s so strange—suddenly, I don’t feel like wearing my earphones anymore.
A. Our instruments are changing quickly.
B. I also have wires hanging from my ears.
C. In the home situation, teenagers love these wires.
D. I don’t have to deal with the noise from the environment.
E. After all, I am listening to my favorite music and would rather not be disturbed.
F. Listening to music through earphones is the perfect way to ignore such interruptions.
G. They walk around in their own spaces, with their personal “digital noise reduction systems”.

Like the Five Olympic Rings from which they draw their color and inspiration, the Five Friendlies will serve as the Official Mascots of Beijing 2008 Olympic Games, carrying a message of friendship and peace and blessings from China to children all over the world.
Designed to express the playful qualities of five little children who form an intimate circle of friends, the Five Friendlies also embody the natural characteristics of four of China’s most popular animals—the Fish, the Panda, the Tibetan Antelope, the Swallow—and the Olympic Flame.
Each of the Friendlies has a rhyming two-syllable name—a traditional way of expressing affection for children in China. Beibei is the Fish, Jingjing is the Panda, Huanhuan is the Olympic Flame, Yingying is the Tibetan Antelope and Nini is the Swallow.
When you put their names together—Bei Jing Huan Ying Ni—they say “Welcome to Beijing,” offering a warm invitation that reflects the mission of the Five Friendlies as young ambassadors for the Olympic Games.
The Five Friendlies also embody both the landscape and the dreams and aspirations of people from every part of the vast country of China. In their origins and their headpieces, you can see the five elements of nature—the sea, forest, fire, earth and sky—all stylistic rendered in ways that represent the deep traditional influences of Chinese folk art and ornamentation.
