Q: Read the article and select the best answer. Article: On the old-time farm in America, there were chickens, cows, pigs and horses. But there were very few machines. Most of the work was done by the farm family. Sometimes more workmen were needed in busy seasons. Work done by horses took up 79 percent; by men, 15 percent; and machine work only took up 6 percent. Today all that has changed. On many modern farms machines now will do 96 percent of the work, while man does 3 percent. As for horses, they do 1 percent of the whole work. The children go to school by bus every morning; the parents work on the farm or in the house and other people's help is hardly needed. Their work has been replaced by a whole army of farm machines. Question: Which part of the farm work has changed most greatly? Options: A: Horses. B: Machine. C: Farm family. D: Outside help.
A: D

Q: Read the article and select the best answer. Article: Owning a smartphone may not be as smart as you think. They may let you surf the Internet, listen to music and take photos wherever you are, but they also turn you into a workaholic . A study suggests that, by giving you access to emails at all times, the smartphone adds as much as two hours to your working day. Researchers found that Britons work an additional 460 hours a year on average as they are able to respond to emails on their mobiles. The study shows the average UK working day is between 9 and 10 hours, but a further 2 hours is spent responding to or sending work emails, or making work calls. Almost one in ten admits spending up to three hours outside their normal working day checking work emails. Some workers say they are on call almost 24 hours a day. Nearly two-thirds say they often check work emails just before they go to bed and as soon as they wake up, while over a third have replied to one in the middle of the night. The average time for first checking emails is between 6 am and 7 am, with more than a third checking their first email in this period, and a quarter checking them between 11pm and midnight. Ghadi Hobeika, marketing director of Pixmania, said: "The ability to access millions of applications has made smartphones invaluable for many people. However, there are disadvantages. Many companies expect their employees to be on call 24 hours a day, seven days a week, and smartphones mean that people cannot get away from work. The more constantly in touch we become, the more is expected of us in work . " Question: With a smartphone the average UK working day is _ . Options: A: 2 hours B: 9 to 10 hours C: 11 to 12 hours D: 24 hours
A: C

Q: Read the article and select the best answer. Article: They may be just passing your office, computer bag slung over one shoulder. Or they may be sitting in a car outside it, causally tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets. Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled several streets in the City of London seeking evidence of wireless networks in operation. Of 124 that they identified, 83 were sending data without encrypting them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet. The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users. Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated in order to give a minimum level of security, for example, by encrypting the data being passed over the network. Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls. Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can... Question: Raymond Kruck most probably agrees that wireless network security involves _ . Options: A: wireless signal administration B: changes in user's awareness C: users' psychological health D: stronger physical walls
A: B

Q: Read the article and select the best answer. Article: Yesterday I started the Year of Giving, my first day of a year-long journey into exploring the act of giving and the meaning of charity. I chose December 15 as the starting date, which marked three years since my mother died from heart disease. She was one of the most generous people that I have ever known. She always thought of others first and certainly serves as an inspiration to me. I had a rather busy day yesterday, ironic for someone who is unemployed right now. In the morning I went to the gym, and unsuccessfully got the phone call from the unemployment office for some job searching. Before I knew it, it was noon. I grabbed a quick lunch and rushed down to a meeting. On my way to Connecticut, I wondered if I would see someone that I would feel forced to give my first $10 to. I was running late and decided to do it afterwards. After the meeting I had about half an hour to find the first person of my Year of Giving! I decided to check out Dupont Circle. I had met a guy there named Jerry once and thought he would willingly accept my first $10. He wasn't there, but I did see a man sitting by himself who looked really lonely, so I approached him. Now I had to figure out what I was going to say. I think I said something like, "Hi, can I sit down here?" "I would like to know if I could give you $10?" He asked me to repeat what I had said. I did, then he looked at me funny, got up and left. I then started walking south where I spotted a man standing by the bus stop on Connecticut Ave. He appeared to be in his 60s. I don't know what drew me to him, but I thought I would make my second attempt. I was a bit nervous and asked him which bus came by that stop. Then I explained that I was starting a year-long project to give $10 to someone every day and that I wanted to give my $10 for today to him. The gentleman, I later found out that his name was Ed, responded without hesitation that he could not accept my offer and that there were many people more deserving the money than him. This was exactly one of the things... Question: The author set the starting date on December 15 to _ .
