Every one of us gets so used to punctuation marks that not many of us give them a second thought. Actually, the ancient Greeks wrote this way. The lack of punctuation marks probably didn't bother good readers, though. As they read, they just put pauses where they fit best. Also at this time, sentences switched directions. A sentence read from left to right. The next one read right to left, and then left to right again, etc. The ancient Romans sometimes punctuated like this: They * put * something * that * can * separate * words * in * a * sentence. The word punctuation actually comes from this idea and the Latin word punctum, which means a dot. When the 5thcentury arrived, there were just two punctuation marks: spaces and points. The spaces separated words while the points showed pauses in reading. Then in the 13thcentury, a printer named Aldus Manutius tried to standardize punctuation. He always used a period for a complete stop at the end of a sentence. He used a slash (/) to indicate a short pause. Over time, that slash was shortened and curled, and it became the modern comma . Since that time, other marks have enlarged the punctuation family. The exclamation mark comes from the Latin word io. It means "exclamation of joy." The question mark originally started out as the Latin word questio, meaning question. Eventually, scholars put it at the end of a sentence to show a question. Punctuation even keeps changing nowadays. New marks are coming into existence, and old punctuation marks are used in new ways. Take for example the "interrobang". This 1962 invention combines the question mark and exclamation mark for times when writers want both. For example, "She did what?" or "How much did you pay for that dress?" Obviously, the interrobang is not widely used or recognized yet, but its invention shows that English is not yet finished with its punctuation. Question: We can learn from the passage that _ . - ancient Romans didn't use any punctuation marks - exclamation and question marks came from Latin - spaces and slashes were already used before the 5 thcentury - Aldus Manutius first started to use commas
exclamation and question marks came from Latin

Whether it could or not, some people are worrying about the possibility that phones, power lines and Wi-Fi could be responsible for a range of illnesses, from rashes to brain tumors. Some say there is evidence to support the growing anxieties. David Carpenter, a professor of environmental health sciences at the university at Albany, in New York, thinks there's a greater than 95 percent chance that power lines can cause childhood leukemia . Also there's a greater than 90 percent chance that cell phones can cause brain tumors. "It's apparent now that there's a real risk, " said Carpenter. But others believe these concerns are unjustified. Dr Martha Linet, the head of radiation epidemiology at the US National Cancer Institute, has looked at the same research as Carpenter but has reached a different conclusion. "I don't support warning labels for cell phones, " said Linet. "We don't have the evidence that there's much danger. " Studies so far suggest a weak connection between EMFs and illness-- so weak that it might not exist at all. A multinational investigation of cell phones and brain cancer, in 13 countries outside the US, has been underway for several years. It's funded in part by the European Union, in part by a cell phone industry group. The final report should come out later this year, but data so far don't suggest a strong link between cell phone use and cancer risk. Question: From the passage we can learn that some people are worried because _ . - they have evidence that the use of cell phones can lead to cancer - they make a fuss over cell phone use - some experts have given a warning - cell phones are responsible for brain tumors
some experts have given a warning

Read the following article and select the best answer. Article: Our education system was invented. There were no public systems of education before the 19th century. They all came into being to meet the needs of industrialism. So the most useful subjects for work are at the top and you were probably driven away from what you did as a kid at school--things you liked--because you would never get a job doing that. Is that right? Don't do music. You're not going to be a musician. Don't do art. You're not going to be an artist. In addition, the whole system of public education around the world is a process of university entrance. And the consequence is that many highly talented, brilliant, creative people think they're not because the thing they were good at wasn't valued at school. I think we can't afford to go on that way. In the next 30 years, more people worldwide will be graduating through education than since the beginning of the history. Suddenly, degrees aren't worth anything. When I was a student, if you had a degree, you had a job. But now you need a Master's degree where the previous job required a Bachelor, and now you need a Ph.D. for the other. It's a process of academic inflation , and it indicates the whole structure of education needs changing. All the great teachers I've ever met and worked with are people who can inspire interest and curiosity and light up people's imaginations with the interests they themselves have for a particular field of work. I mean, teaching is not only a process of giving people direct instructions and information they have to memorize, it is much more than that. I believe our only hope for the future is to rethink the fundamental principles on which we are educating our children. And our task is to educate their whole being so they can face the future. By the way, we may not see this future, but they will. And our job is to help them make something of it. Question: Things little kids like to do are not taught at school because they _ . - are not useful for making a living - are not challenging enough for students - don't meet the expectation of parents - don't fit in classroom teaching
are not useful for making a living
