I did, and he was grateful.“Thank you,” he said.“I’m glad I could help. I just thought it would be easier for me to reach,” I said. He was a disabled man, and forced to look down most of the time. His arms and legs were twisted terribly, and he couldn’t do what the rest of us would consider easy tasks. He always managed to look up to see how you reacted to his words, however. He had a big smile, making me feel comfortable. I was still on my knees by his wheelchair.“ Nice shoes,” he said.“Thanks.

B4. we usd 2 go 2 NY 2C my bro, his GF £¦ thr 3 : -@ kids FTF. ILNY, its gr8. Can you understand this sentence? If you can’t, don't feel too bad: neither could the middle school teacher in England who received this as homework. This is Netspeak: the language of computerized communication found on Internet or cellphones. To newcomers, it ran like a completely foreign language. So, what is the "translation" of the sentence above? My summer holidays were a complete waste of time. Before, we used to go to New York to see my brother, his girlfriend, and their three screaming kids face to face.I love New York; it’s great. Schoolteachers and parents say this new form of writing is harming the English language. Increasing spelling and grammatical mistakes can be seen in students' writing. They fear the language could become corrupted (ÃæÄ¿È«·ÇµÄ). Everyone should just relax, say linguists (ÓïÑÔѧ¼Ò). They believe Netspeak is in fact more of a good thing. David Crystal, from the University of Wales, argues that Netspeak and Internet create a new language use and the almost lost art of diary writing has been picked up again. Geoffrey Nunberg, from Stanford University, agrees. "People get better at writing by writing," he says, “Kids who are now doing text messaging, e-mail, and instant messages will write at least as well as, and possibly better than their parents." Linguist James Milroy says, for centuries, it is believed without exception that young people are harming the language. And you can bet your bottom dollar that when today's teenagers become tomorrow's parents, they too will think this way, Milroy argues that languages do not and cannot become "corrupted"; they simply change to meet the new needs. However, Netspeakers do agree that it is important to teach young people how to speak and write Standard English. Cynthia McVey says, "I can understand Netspeak worries teachers and it's important that they get across to their pupils that text messaging is for fun, but that learning to write proper English is a must for their future.” Perhaps we should give teenagers a little more trust anyway. Erin, age 12, says, "I wouldn't use text language in my homework. Texting is just for fun."ÕýÈ·´ð°¸:(ÔĶÁÀí½â)33: What might the future be like? Here are some predictions: things to come, things to go. The Spring Festival, the most important Chinese holiday when everyone returns home, has caused headaches for millions of Chinese. More than 2 billion people travel at the same time, making getting travel ticketsand the journey difficult. But in 28 years, Spring Festival travel may not be a problem at all. China plans to build more than 120,000 kilometers of railway and a fast transportation network that will serve 90% of the population by 2020. And because most of China will be cities, people will not have to go to other places to find a job, so it will no longer be a problem. Newspaper will come to an end in 2043. In the future, digital newspapers will be sent to personal web tools through Internet. Readers can discuss topics with journalists and editors. Information will move faster. Oil is running out faster than expected. But scientists have found something else for oil as fuel. Coal, natural gas, solar power, nuclear power and even water can take the place of oil as sources of energy. Schools will go electronic. Computers will be important and popular among the students. Everything will be in the computer and students will not need to bring books to school. They will find information on the Internet. A computer will be the students’ library, schoolbag and connection to the outside world. There will be robot teachers, they will check homework on computers and communicate with the students’ parents through e-mail. And school buses will be like spaceships, comfortable and safe.ÕýÈ·´ð°¸:(ÔĶÁÀí½â)34: More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that’s why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost! Get on a bicycle and ride around your neighborhood. You may discover something new all around you. Stopping and getting off a bike is easier than stopping and getting out of your car. You can bike to work and benefit (ÊÜÒæ) from the enjoyable exercise without polluting the environment. You don’t even have to ride all the way. Folding (ÕÛµþ) bikes work well for people who ride the train. Just fold the bike and take it with you. You can do the same on an airplane. A folding bike can be packed in a suitcase. You can also take a common bike with you when you fly. But be sure to look for information by getting on airline websites. Not all airlines are bicycle-friendly to travelers.Health Benefits of Bicycling:? It helps to prevent heart diseases.? Bicycling helps to control your weight. A 15-minute bike ride to and from work three times a week burns off five kilos of fat in a year.? Bicycling can improve your mood. Exercise like bicycling has been shown to make people feel better, more relaxed andself-confident.? Bicycling is healthier than driving.ÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)1: If you want to learn English well, don’t forget intensive reading and _____ reading.A: extendedB: extensiveC: wideD: externalÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)2: He excited at the good newsA: lookB: appearsC: disappearD: feelÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)3:When I got to his home, he ____ ____ for an hour.A: had leftB: leftC: had been awayD: has been awayÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)4: He left the spot immediately, afraid of being ____ in the car accident.A: connectedB: takenC: seatedD: involvedÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)5: Will there be a strong wind ____ the north ______ the Huanghe River ?A: to... ofB: to... offC: at... ofD: on… offÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)6: Scientific discoveries are often applied_____ industrial production methods.A: for B: with C: to D: onÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)7: I asked the bank for a _____.A: loafB: loadC: loanD: loamÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)8: The teacher required that all the assignments _____finished before this weekend.A: would beB: wereC: beD: are toÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)9:Everyone except Tom and John ______ there when the meeting began.A: isB: wasC: areD: wereÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)10: A good habit can make our mental health in with physical health.A: concernB: connectionC: compareD: tuneÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)11: May she _______ with you?A: comeB: comesC: comingD: cameÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)12: Which is the best approach _____ the tunnel?A: toB: withC: besidesD: towardsÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)13:He could_____ neither French or German,&n bsp;so I____ with him in English.A: speak, talkedB: talk, toldC: say, spokeD: tell, talkedÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)14:Don’t spend _______ time on compute r games.A: too muchB: much tooC: too manyD: many tooÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)15: Many girls like __________ skirts in summer.A: wearingB: dressingC: inD: putting onÕýÈ·´ð°¸:(µ¥Ñ¡Ìâ)16:Look!
