The lights dimmed，the musical hall grew quiet and out walked the conductor (指挥) shiny and white and 4 feet and 3 inches tall.
ASIMO, a robot designed by Honda Motor Co., met its latest challenge Tuesday evening: Conducting the Detroit Symphony (底特律交响乐团), in a performance of “The Impossible  Dream” from “Man of La Mancha”．
“Hello, everyone，” ASIMO said to the audience in a childlike voice, then waved to the orchestra. As it conducted, it perfectly mimicked (模仿) the actions of a conductor,
nodding its head at various sections and gesturing with one or both hands. ASIMO took a final bow to excited shouts from the audience. Later, cellist Yo－Yo Ma joined ASIMO onstage to receive an award for his efforts in music education.
Honda spokeswoman Alicia Jones says it is the first time ASIMO has conducted an orchestra, and it may be the first time any robot has conducted a live performance. But ASIMO has its  limits. ASIMO's engineers programmed the robot to mimic Charles Burke, the Detroit Symphony's education director, as he conducted the piece in front of a pianist about six months ago. But it can't respond to the musicians.
“It's not a communicative device. It simply is programmed to do a set of gestures，” said Leonard Slatkin, the orchestra's musical director. “If the orchestra decides to go faster, there's nothing the robot can do about it. Hopefully, I keep that under control.”
But several musicians also said ASIMO was more realistic than they expected. “The movements are still a little stiff (僵硬的), but very humanlike, much better than I thought，” Hutchinson said.
What's the audience's response to ASIMO's performance?

Whose conducting was ASIMO made to copy?

We can learn from the passage that ASIMO ________.

What would be the best title for this passage?

If you've been joining in chat room conversations, or trading e－mails with net pals (网友), you have become one of the millions who write in a special, short form of English.
Throughout the world, every night children and their elders are “talking” online－many of them are talking at the same time.
It's fast: trying talking to six people once. It's convenient: three or four words per exchange. It takes cleverness, concentration and quick fingers.
And it requires very simple language. There's neither time nor space for explanations. Why waste valuable time telling six friends you have to leave for a moment to take care of your little brother when BRB (be right back) will do?
Want to enter a conversation? Just type PMFJI (pardon me for jumping in)．
Interested in whom you're talking to? Type A/S/L, the nearly universal request to know your pal's age, sex and location. You may get 15/M/NY as a reply from your pal.
If something makes you laugh, say you're OTF (on the floor), or LOL (laughing out loud), or join the two into ROTFL (rolling on the floor laughing)．
And when it's time to get back to work or go to bed, you type GTG (got to go) or TTYL (talk to you later)．
People want to write as fast as possible, and they want to get their ideas across as quickly as they can. Capital letters are left in the dust, except when expressing feeling, as it takes more time to hold down the “Shift” key and use capitals. Punctuation (标点) is going too.
When people are online, they talk by ________.

The underlined sentence in Para. 4 means that ________.

If you get 17/F/NY as an answer to your A/S/L, it means________.

Which of the following is a way to save online time?

Come October and everybody is busy making Christmas plans. The most important thing other than making decisions on buying gifts is decorating your Christmas tree. 
Decorating Christmas trees involves every member in the family to contribute and do whatever they can to help with the decorations.  Decorating Christmas trees is a fun activity that everyone in the family enjoys doing. Therefore, for innovative (创新的) ideas, it is best to get the whole family together after dinner and have a brain storming
session for new ideas. Children are really innovative and can come up with great suggestions. Well here are some additional ideas that can be beneficial and help you create that new look for your Christmas tree this year.
For decorative purposes it is better that you get an artificial tree. Select a unique theme and look for ideas to create your own decorations. The Internet is a good source for unique ideas and themes. Go in for light decorations that are truly different. Start your shopping early to look for those special lights especially at your local stores. You can even have a personalized Christmas tree theme where you have all your family members' photos hung
from various branches. Hang out of the world decorative pieces that truly stand out. Search for these at your local store or even your attic where you are sure to find some of those long forgotten decorative pieces that have been handed down to you by your grandmother. You can even use dried flowers or make some of your own artificial flowers as decorations.
If you feel you cannot come up with any great ideas, there is no reason to worry. The Internet is full of them. Make a thorough search and you are sure to find a good idea. You can then try innovating on that idea by making your own unique decorations. Enjoy yourself!

Children are getting so fat that they may be the first generation to die before their parents, an expert says.
Today's young people will be affected by potential (潜在的) killers such as heart disease because of their weight. Fatty fast－food diets combined with the lifestyles with televisions and computers could mean kids will die young, says Professor Andrew Prentice, from the London School of Hygiene and Tropical Medicine. At the same time, the shape of the human body is going through a great change because adults are getting so fat.
Here in Britain, the latest research shows that the average waist size for a man is 36～38 inches and may be 42～44 inches by 2032.This compares with only 32.6 inches in 1972. Women's waists have grown from an average of 22 inches in the 1920s to 24 inches in the 1950s and 30 inches now. One of the major reasons why children now are at greater risk is that we are getting fatter younger. In the UK alone, more than one million under 16 years old are thought
to be overweight or fat—double the number in the 1980s. One in ten of four－year－olds are also medically said to be obese.
The obesity which started in the US, has now spread to Europe, Australia, Central America and the Middle East. Many nations now record more than 20 percent of their population as obese and well over half of the population as overweight.
Professor Prentice says the change in our shape has been caused by high－energy foods combined with a dramatic (急剧的) drop in the energy we use as a result of technology developments.
He is not alone in his concern. Only last week one medical magazine revealed how obesity was fuelling a rise in cancer cases. Obesity also increases the risk factor for heart disease and so on. An averagely obese person's lifespan (寿命) is shortened by around nine years while a seriously obese person by much more.
Professor Prentice says,
“So_will_parents_live_longer_than_their_children,_as_an_American_obesity_expert_said_recently？”
“The answer is yes—and no.” Yes, when most children become obese. No, because this is now becoming an alarmingly serious problem in the US. “Such children will have a greatly reduced quality of life on both body and mind.”
So say “No” to sandwiches and hamburgers.
From the second paragraph, we know that ________.

According to Professor Prentice, people become fatter because ________.

For the underlined question, the answer “no” suggests ________.

I watch TV until 12 o'clock, so I could not go over my lessons. This morning I got up very late that I had to go to school without breakfast in hurry but I was late for the first class. When I entered the classroom, the maths teacher had to stop explain an important problem, and all the eyes fixed upon me. My face turned red. Something even worse was happened to me in English class. The teacher asked me to recite the text, yet I could speak nothing but sorry, for I did not spend any time preparing my lessons. The teacher looked at me with his coldly eyes. I stood at my bench without dare to raise my head. How a terrible day I had! I will never do anything like this.
