Before this time,people only had two meals a day--breakfast and dinner. In the 16th century,breakfast was only to break one's fast . But 200 years later it had become a large meal,not just for family,but for numbers of guests as well. It was a social event. It began at 10 a.m. and lasted until 1 p.m. Then breakfast began to be less popular. It became,instead,a lighter meal and was taken at a much earlier hour. By 1850 it had been pushed back to 8 a.m. and became a family meal. Dinner,however,went to the other way. In the 16th century it was eaten at 11 a.m. Years later,it had moved to the early afternoon,then to 5 p.m. By 1850 dinner time had reached 7 p.m. Lunch is a recent idea. It first appeared as a snack to fill the gap between breakfast and dinner. Question: The passage leads us to believe that _ . Options: A: our custom of meals is based on English custom B: the body can adjust to two or three meals a day C: breakfast is the most important meal for us D: before 1890 people didn't eat three meals a day

Article: When I began planning to move to Auckland to study,my mother was a little worried about the uncertainty of living in a place that was so different from India,where we lived. She worried particularly about the lack of jobs,the cultural differences and the chance that I would face racism. Despite these worries,I came to New Zealand in July 2009. I have found the place and people very nice and supportive. Soon after I arrived,I realized the importance of getting a job to supply my living expenses. Determined to do this on my own ,I spent a whole day going from door to door asking for a job. However,I received little or no response. This became my routine every day after college for a few weeks. One afternoon,I walked into a building to ask if there were any job opportunities. The people there were very surprised,and advised me not to continue my job search in that manner. As I was about to leave,a clerk in the building,who had been listening to what the others had said, approached me and asked if I would wait outside. Fifteen minutes later,he returned. He asked me what my plans were and encouraged me to stay confident. He then offered to take me to the Royal Oak area to search for a job. I was a little surprised,but had a good feeling about him,so I went along. Along the way, I realized that I had run out of copies of my resume .The man stopped at his business partner's office to make me 15 extra copies. He also gave me tips on dressing and speaking,and added that I should give him, a call if I ever needed anything. I handed out my resumes and went home feeling very satisfied. The following day,I received:call from. store in Royal Oak offering me a job. It seems that the world always gives back to you when you need it. And this time,it was a complete stranger who turned out to be a real blessing. Question: After staying in New Zealand for a short time, the author Options: A: decided to go back to his own country B: felt the local people were not very friendly C: had to find a job to cover his living expenses D: wanted to get a job that needed practical skills

The idea is to prevent thieves from using a stolen card to buy goods online. A model built by engineers in California packs a microphone, a loudspeaker, a battery and a voice-recognition chip into a standard-sized credit card. The card is the length and width of an ordinary credit card but about three times as thick. The company now plans to make it thinner. The voice card is based on an earlier Beep card technology designed to prevent fraud in online deals. The Beep card has no microphone, but has a built-in loudspeaker to utter an audible ID signal by a computer's microphone to an online server . By confirming that signal matches the information in the card, the server can make sure that the user is not simply keying in a credit card number but actually has the card in his hand. The ID code, which only the server knows, changes each time the card is used. This prevents fraudsters recording the beeps, noting the card details and then playing back the audible ID when they key in the details later. But this earlier Beep card technology cannot prevent illegal use of stolen cards. The new voice card can. The new voice card doesn't identify itself by its ID until it has confirmed the real user's spoken password. Thieves will be unable to use the card because even if they knew the password they would have to be able to copy the owner's voice with a high degree of accuracy. The challenge for Beep card has been to develop voice-recognition and audio circuitry . The voice-recognition credit is powered by a mini battery. To extend batter life, the electronics have only to be switched on when the card is being used. Pressing a button on the card's surface allows one to hear a female voice saying, "Say your password." If the voice-recognition software proves that the password is real, it sends its ID, which the server then identifies, allowing the deal to continue. Question: Which of the following about the earlier card is TRUE? Options: A: Its owner can change the ID code at will. B: Its user needn't key in the credit card number. C: It can record its user's spoken password. D: It can be used by someone who has stolen it.

Article: On July 1 at exactly 7:59:59, Bejing time, the world' s atomic clocks will pause for a single second, or, more precisely, change to the unusual time of 7:59:60. The addition of a leap second , is to keep our clocks in time with the slowing of Earth' s rotation and astronomical time as measured by the sun. Just one extra second could affect the way computers and websites work, however. When the last leap second was added back in 2012, the community website Reddit crashed. For Reddit, the problem was that a Linux system got confused when it checked the network time and found an extra second. Speaking to Wired about the problem back in 2012, Linux creator Linus Torvalds commented:"Almost every time we have a leap second, we find something. It' s really annoying, because it' s code that is almost never used, and thus not tested by users under their normal conditions. " Companies have thought of their own solutions, and Google' s"leap smear"may be the best- known example. As company engineer Christopher Pascoe explains in a blog post, companies usually try to turn back the clocks by one second at the end of the day so that they play that second again. However, Pascoe believes this creates problems. He asked:"Does email that comes in during that second get stored correctly?"Google has a solution: Cut the extra second into milliseconds and then put these tiny amounts of time into the system throughout the day."This means that when it became time to add an extra second at midnight."Says Pascoe."Our clocks have already taken this into account over the course of the day." For many companies without Google' s money, however, the leap second will likely still cause some crashes. Question: What' s Pascoe' s attitude toward Google' s solution to the problem? Options: A: Ambiguous. B: Approving. C: Doubtful. D: Cautious.
