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!
46. 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
47. Which of the following is NOT true according to the passage?
A. Copper compounds are needed to make green in fireworks.
B. Chemicals in fireworks are both poisonous and dangerous.
C. Too much gases from fireworks can result in acid rain.
D. Chemicals in fireworks are harmful in the air and on the ground.
48. All the underlined words are probably _____________.
A. mineral materials B. tiny solids
C. chemical elements D. broken pieces
49. What is implied from the passage?
A. Gunpowder in fireworks makes loud booming noises.
B. It must be Indians who first started to hang sky lanterns.
C. Fireworks does less harm in the air than on the ground.
D. Fireworks can even break the balance of nature.
50. What can be concluded as the writer’s attitude towards fireworks?
A. It is not allowed to set off fireworks except during the holidays.
B. Fireworks should be banned and replaced by some other means.
C. Night is the best time to set off fireworks and see the pretty colors.

Most French teens love music, with 86% putting it as their top hobby, above the cinema, sport and television. French kids read a lot and like different things, from Japanese cartoons to American novels. Many French people worry that their children watch too many American films and listen to too much American music. But the results of this survey show that French young people like their own culture.

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. Are you one of “them”?
For me, walking around in my own personal bubble is perfect. 1.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, you don’t want anyone to break your concentration. 2. Those wires hanging from your ears would be sure to give the “Go away!” signal.
3. 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 (声音) 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 instrument. We’ll be in a virtual (虚拟) world, communicating with everyone else, or choosing not to, as we like. 4. 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, 5.
A. Our instruments are changing quickly.
B. I also have wires hanging from my ears.
C. In the home situation, teenagers love these wires.

E. I don’t have to deal with the noise from the environment.
F. After all, I am listening to my favorite music and would rather not be disturbed.

He knew his colors and shapes, he learned more than 100 English words, and with his own brand of one-liners he established (确立) himself in TV shows, scientific reports, and news articles as perhaps the world’s most famous talking bird.
But last week, Alex, an African parrot, died, obviously of natural causes, said Dr Irene Pepperberg, an expert at Brandeis University and Harvard who studied and worked with the parrot for most of its life and published reports of his progress in scientific journals. The parrot was 31.
Scientists have long debated whether any other species can develop the ability to learn human language. Alex’s language ability was, in some ways, more surprising than the efforts of those animals that have been taught, like Koko, the gorilla (猩猩) trained by Penny Patterson at the Gorilla Foundation in Woodside, or Washoe, another gorilla studied by R. Allen and Beatrice Gardner at the University of Nevada in the 1960s and 1970s.
When Dr Pepperberg, who was then a doctoral student in chemistry at Harvard, found Alex was good at remembering words in a pet store in 1977 and bought it, scientists had little expectation that birds could learn to communicate with humans. Most of the research had been done on pigeons, and was not promising.
But by using novel methods of teaching, Dr Pepperberg taught Alex to learn about 150 words, which he could put into categories. He could count small numbers and tell colors and shapes. “The work changed the way we think of bird brains,” said Diana Reiss, a psychologist at Hunter College who works with dolphins and elephants. “We used to look down upon those birds, but now we look at those brains — at least Alex’s — with some awe.”
1.Alex is very famous because ________.
A. it died of a strange disease
B. it lived longer than any other parrot
C. it hosted many famous TV shows
D. it has a special talent in learning human language
2.What was the direct reason why Dr Pepperberg bought Alex?
A. He found it was good at remembering words.
B. He liked its colors and shapes.
C. He wanted to do research on birds.
D. Diana Reiss asked him to do that.
3.What does the underlined word “novel” mean in the last paragraph?
A. Special. B. New.
C. Great. D. Unique.
4.According to the last paragraph, we can learn that ________.
A. people used to think dolphins were the cleverest
B. Alex’s ability of learning human language has changed some researchers’ ideas about birds
C. elephants are better at learning human language
D. birds’ great ability in learning human language has already been noticed before
5.What would be the best title for this passage?
A. Who are cleverer, birds or gorillas?
B. A famous talking bird died
C. Have you ever talked with a bird?
D. The keeper of a famous bird
