"Dear anybody. Your email address has been chosen by our computer. So, for no reason, we'd like to give you a million dollars. All you need to do is give us your bank account numbers. Can we interest you in some diet pills? And, by the way, I want to marry you." I hate to let you down, but there is no "million dollars". The diet pills don't exist - and your future "husband" or "wife" has just proposed to a million others. These and a hundred other stories have been made up to steal your personal information or money or maybe just to infect your computer with a virus. Welcome to the world of junk email. Junk email - or spam - is probably the biggest global business that's ever existed. Billions of spam emails are sent every day, making up around 80% of all email traffic. These incredible volumes of spam slow down the whole internet and cost businesses millions of dollars just trying to keep up with the next trick. Your email programme probably includes a spam filter, which sorts out the mail you do want from the junk. But it's impossible to stop it all and if you put together the seconds it takes to see through the deception in each one, they add up to a significant amount of lost time dealing with the spam that does get through. But who could fall for such obvious tricks? Probably very few of us - one in a million, perhaps. But when you are sending billions of these every day, for next to no cost, it doesn't take a genius to work out that someone is getting very rich. But who? It's incredibly difficult to find out. Most spam is sent using anonymous networks of infected computers, called "botnets", some of which are made up of tens of millions of computers across dozens of countries. Maybe your own laptop is sending out marriage proposals right now. It's enough to put you off using email again! So what can you do to defend yourself? You could set up a separate email account for online use, or maybe leave out the @ symbol when you write your email address online. An up-to-date web browser and antivirus... The passage is mainly about _ . A) the problem of junk mail B) the profits of junk mail C) protection against junk mail D) the harmful effects of junk mail

We are going to talk again this week about higher education for disabled students who want to study in the United States.As we noted last time,there are no special colleges or universities for blind students.But there are for deaf students.One of them is Gallaudet University in Washington,D.C. Gallaudet is said to be the world's only liberal arts university where everything is designed for deaf or hard-of-hearing students.About 2,000 students attend Gallaudet.The cost for international students is about 33,000 dollars a year. Financial aid is available in the form of scholarships,but only after the first year of studies. Most scholarship aid goes to students in financial need who do well in their first year.One scholarship for international students is for deaf students from developing countries.Another is just for students from China.The university also offers an English Language Institute.But Gallaudet says this program does not guarantee acceptance to the university. In the past year,students at Gallaudet protested against the administration's choice of a new president for the university.The protests led to the choice of a different president who is more popular with the students,Robert Davila.He is a former officer of the National Technical Institute for the Deaf.This technical college is in Rochester, New York. It is one of the eight colleges in the Rochester Institute of Technology. More than one thousand students attend the National Technical Institute for the Deaf. About one hundred of them are international students.They come from Africa, Asia,Europe and South America. The cost is about 28,000 dollars a year for an international Technical Institute student.Foreign graduate students pay about 20,000 dollars. Both undergraduate and graduate student can receive limited financial aid. They can also take part in the student employment program.This program makes it possible for students to work at the school. The passage is written for _ . A) blind students B) deaf students C) art students D) dumb students

Q: Dae Jon is the city in South Korea, where I was born and grew up. There was a public park there. It was a very popular place, and I have tons of precious memories from times spent there. Our teachers often took us to that park for a spring or fall picnic. When I learned martial arts --Tae Kwon Do, my master usually took us there to train us. There was a hill there which was not high, so I could reach the peak within forty minutes even though I was very young. From the peak, I could see a lot of places if it was a sunny day. There was a huge rock on the top called Eagle Rock because the shape of the rock looked like the head of an eagle. We spent lots of fun days there. We played hide-and-seek within the limited area, and we sometimes caught frogs and fish in the pond. When we felt thirsty, we enjoyed drinking cold spring water. When I was a ten-year-old boy, I usually went to the park with my father to exercise early in the morning. It was quite dark, so I sometimes felt afraid, but after I got used to going there, I enjoyed breathing the fresh air and hearing the birds sing. Recently, I went back to the park to remember my good times there. When I arrived at the entrance, I was surprised because it didn't seem to be the same as I remembered it. Everything has changed in the thirteen years since I last saw it, but the good memories soon came back. I could almost imagine a boy playing there with a slight smile and shaking hands with me. As a child, the writer did the following in the park EXCEPT _ . A) practicing martial arts B) climbing the hill C) swimming in the pond D) playing hide-and-seek

Q: Here is a question I have often asked at dinner parties: You're on an island with only one other person, your best friend. He's dying of cancer. In his final days, he tells you, "I have 100,000 dollars in a bank back home. When I die, make sure my son goes to medical school." Then he dies. But his son is a no-good playboy who has no interest in going to medical school and will waste that money away in a very short time. But your son is entering college, and he is willing to become a doctor. Which one do you give the money to for medical school? I've asked this question of everyone from the president of a famous university to an ordinary young soldier, and it has never failed to get a discussion going. Everyone has an opinion, most of them different, but all of them correct. Sometimes this one topic lasts the whole evening. Why does the writer often ask people such a question? Because _ . A) he wants to find the answer for a research B) he is interested in such a question C) he likes to make fun of people at parties D) he wants to offer people a topic in which everyone could say something
