How many coins have you got in your pocket right now? Three? Two? or One? With a phonecard you can make up to 200 calls without any change at all. 1. _ Go to a telephone box marked "Phonecard". Put in your card to start, make your call and when you have finished, a screen tells you how much is left on your card. It costs no extra for the cards, and the calls cost 10p per unit, the same as any other pay-phone call. You can buy them in units of 10, 20, 40, 100 or 200. 2. _ Near each phonecard place you will find a shop where you can buy one. They're at bus, train and city tube stations. At many universities, hospitals and clubs, restaurants and gas stations on the highway and shopping centers. At airports and seaports. 3. _ Most broken payphones are like that because they've been damaged. There are no coins in a cardphone to excite thieves' interest in it. So you're not probably to find a broken one. Get a phonecard yourself and try it out. Or get a bigger wallet. Which statement of the following is right by inference ? A) Using a phonecard will cost you less money than payphone call. B) Phonecards are easier to carry. C) If a thief steals your phonecard, he can't use it any more. D) When you finish your call, take out your card first and then you will see how many calls you can still make.

Q: People who are obese have a worse memory than their thinner friends, a small study shows. Tests on 50 people showed that being overweight was linked to worse "episodic memory" or the ability to remember past experiences. The study in the Quarterly Journal of Experimental Psychology argues that a less vivid memory of recent meals may lead to overeating. However, other aspects of memory -- such as general knowledge -- show no signs. Tests on rats have previously shown that with burgeoning waistlines come poorer performances in memory tests, but the evidence in humans has been mixed. Fifty people with a Body Mass Index (BMI) ranging from 18 (healthy) to 51 (very obese) took part in a memory test -- a bit like doing a treasure hunt on your own. They had to "hide" objects at different times and on different scenes displayed on a computer screen. They were later asked to recall what they had hidden, when and where. The results showed obese people's scores were 15% lower than thinner people. Dr. Lucy Cheke, from the University of Cambridge, told the BBC News website, "The suggestion we're making is that a higher BMI is having some reduction on the vividness of memory, but they're not drawing blanks and having amnesia . As a matter of fact, if they have a less strong memory of a recent meal, with a less strong impact in the mind, then they may have less ability to regulate how much they eat later on." Hunger hormones play a huge role in how much we eat, but it has already been recognized that our minds have a key role too. Dr. Cheke concluded, "It is too early to talk in terms of advice, but we are certainly beginning to observe how obesity causes itself to continue." Which of the following is TRUE about the experiment? A) The researchers compare the performances of people with various BMIs. B) Fifty subjects are required to seek for objects hidden by the researchers. C) All aspects of memory will be influenced by obesity. D) The number of rats tested is the same as that of people.

Q: Any mistake made in the printing of a stamp raises its value to stamp collectors.A mistake on a two-penny stamp has made it worth a million and a half times its face value. Do you think it impossible? Well,it is true.And this is how it happened. The mistake was made more than a hundred years ago in the former British colony of Mauritius,a small island in the Indian Ocean. In l847 all order for stamps was sent to London Mauritius was about to become the fourth country in the world to put out stamps. Before the order was filled and the stamps arrived from England,a big dance was planned by the commander-in-chief of all the armed forces on the island.The dance would be held in his house and letters of invitation would be sent to all the important people in Mauritius.Stamps were badly needed to post the letters.Therefore,an islander,who was a good printer,was told to copy the pattern of the stamps.He carelessly put the words "Post Office" instead of "Post Paid", two words seen on stamps at that time,on the several hundred that he printed. Today, there are only twenty-six of these misprinted stamps left-fourteen One-penny Reds and twelve Two-penny Blues, Because there are so few Two-penny Blues and because of their age, collectors have paid as much as$16,800 for one of them. In l847 most countries of the world were _ A) not yet using stamps B) printing stamps in Mauritius C) printing their own stamps D) collecting valuable stamps
