Edmund Halley was an English scientist who lived over 200 years ago. He studied the observations of comets which other scientists had made. The orbit of one particular comet was a very difficult mathematical problem. He could not figure it out. Neither could other scientists who dealt with such problems. However, Halley had a friend named Isaac Newton, who was a brilliant mathematician. Newton thought he had already worked out that problem, but he could not find the papers on which he had done it. He told Halley that the orbit of a comet had the shape of an ellipse . Now Halley set to work. He figured out(,)the orbits of some of the comets that had been observed by scientists. He made a surprising discovery. The comets that had appeared in the years 1531, 1607, and 1682 all had the same orbit. Yet their appearance had been 75 to 76 years apart. This seemed very strange to Halley. Three different comets followed the same orbit. The more Halley thought about it, the more he thought that there had not been three different comets as people thought. He decided that they had simply seen the same comet three times. The comet had gone away and had come back again. It was an astonishing idea! Halley felt certain to make a prediction of what would happen in the future. He decided that this would appear in the year 1758. There were 53 years to go before Halley's prediction could be tested. In 1758 the comet appeared in the sky. Halley did not see it, for he had died some years before. Ever since then that comet had been called Halley's comet, in his honor. Edmund Halley figured out the orbit of _ . A) some different comets appearing several times B) the same comet appearing at different times C) three different comets appearing at the same time D) several comets appearing at the same time

(Question)
Jerry was a unique manager because he had several waiters who had followed him around from restaurant to restaurant. The reason the waiters followed Jerry was because of his attitude. He was a natural motivator. If an employee was having a bad day, Jerry was there telling the employee how to look on the positive side of the situation. Seeing this style really made me curious, so one day I went up to Jerry and asked him, "I don't get it! You can't be a positive person all of the time. How do you do it?" Jerry replied, "Each morning I wake up and say to myself, 'Jerry, you have two choices today. You can choose to be in a good mood or you can choose to be in a bad mood.' I choose to be in a good mood. Each time something bad happens, I can choose to be a victim or I can choose to learn from it. I choose to learn from it. Every time someone comes to me complaining, I can choose to accept their complaining or I can point out the positive side of life. I choose the positive side of life. The bottom line: It's your choice how you live life." I reflected on what Jerry said. Later, I left the restaurant industry to start my own business. We lost touch, but I often thought about him when I made a choice about life. Several years later, I heard that Jerry did something you are never supposed to do in a restaurant business: he left the back door open one morning and was held up at gun point by three armed robbers. While trying to open the safe, he forgot the password, nervous. The robbers panicked and shot him. Luckily, Jerry was found relatively quickly and rushed to the local hospital. After 18 hours of surgery and weeks of intensive care, Jerry was released from the hospital with fragments of the bullets still in his body. I saw Jerry about six months after the accident. When I asked him how he was, he replied, "The first thing that went through my mind was that I should have locked the back door," Jerry replied. "Then, as I lay on the floor, I remembered that I had two choices: I could choose to live, or I could... Which of the following is conveyed in this article? A) Where there is life, there is hope. B) Everything comes to him who waits. C) Humor is the best medicine that creates miracle. D) Attitude determines everything.

Ques: By today's standards, my mobile phone is pretty rubbish. It's a Nokia 1616. If that doesn't mean much to you ( it's not the kind of phone you see advertised on television) ,all you need to know is that it's a small, not very heavy device with which you can send and receive telephone calls and text messages. It also has a very handy torch on the top for when you can't find your keys, or when you drop something on the floor in the cinema. Apart from that, my phone doesn't do much. Well, it has an alarm, and it probably has a calculator and things like that, but it's nothing compared to a smartphone. Why would I want one of those? I have often been told that the big advantage of having a smartphone is that " you can do everything with them!" But when was the last time you saw someone doing "everything" with a smartphone? Okay, so they may have an endless list of functions, but generally they are used for checking social networking sites, playing games, and receiving and replying to emails. I'm happy just doing all of those things at home on my laptop. As far as I can tell, the best thing about having a smartphone is that you can be connected to the internet all the time. Don't get me wrong, I love the internet, but I just don't see the point of constantly being online. I can't remember the last time I received a Facebook update which was so urgent that I had to read it as soon as it appeared, and I can't imagine ever having a job which was so important that I would need to read work-related emails immediately. I would think that if someone needed me urgently, they would just ring me rather than send an email. And my trusty Nokia can manage that. One of the most peculiar effects of the smartphone is, in my opinion, the newly-found addiction to maps and navigation systems. Is there anything more boring than knowing exactly where you are all of the time? How do you get to know an area if you don't get lost there a few times? And if you are dependent on online maps, what happens to those great places you... The writer uses his Nokia 1616 mainly to _ . A) play online games B) do calculating work C) check social network sites D) make calls and text messages
