thisthe alternative use of your cash and timeis the opportunity cost. for economists, every decision is made by knowledge of what one must forgoin terms of money and enjoymentin order to take it up. by knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. consider that most famous economic rule of all: theres no such thing as a free lunch. even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities. some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. yet, in a sense its human nature to do precisely thatwe assess the advantages and disadvantages of decisions all the time. in the business world, a popular phrase is “value for money. ”people want their cash to go as far as possible. however, another is fast obtaining an advantage:“value for time. ”the biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. by reading this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. in return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions. 1. according to the passage, the concept of “opportunity cost” is applied to.a. making more moneyb. taking more opportunitiesc. reducing missed opportunitiesd. weighing the choice of opportunities2. the “l(fā)eftover. . . time” in paragraph 3 probably refers to the time. a. spared for watching the match at homeb. taken to have dinner with friendsc. spent on the way to and from the matchd. saved from not going to watch the match3. what are forgone opportunities?a. opportunities you forget in decision-making. b. opportunities you give up for better ones. c. opportunities you miss accidentally. d. opportunities you make up for. 答案1. d2. c3. bbas internet users become more dependent on the internet to store information, are people remembering less? if you know your computer will save information, why store it in your own personal memory, your brain? experts are wondering if the internet is changing what we remember and how. in a recent study, professor betsy sparrow conducted some experiments. she and her research team wanted to know how the internet is changing memory. in the first experiment, they gave people 40 unimportant facts to type into a computer. the first group of people understood that the computer would save the information. the second group understood that the computer would not save it. later, the second group remembered the information better. people in the first group knew they could find the information again, so they did not try to remember it. in another experiment, the researchers gave people facts to remember, and told them where to find the information on the computer. the information was in a specific computer folder(文件夾). surprisingly, people later remembered the folder location(位置)better than the facts. when people use the internet, they do not remember the information. rather, they remember how to find it. this is called “transactive memory(交互記憶)”. according to sparrow, we are not becoming people with poor memories as a result of the internet. instead, computer users are developing stronger transactive memories; that is, people are learning how to organize huge quantities of information so that they are able to access it at a later date. this doesnt mean we are becoming either more or less intelligent, but there is no doubt that the way we use memory is changing. 4. the passage begins with two questions to. a. introduce the main topicb. show the authors attitudec. describe how to use the internetd. explain how to store information5. what can we learn about the first experiment?a. the sparrows team typed the information into a computer. b. the two groups remembered the information equally well. c. the first group did not try to remember the information. d. the second group did not understand the information. 6. in transactive memory, people. a. keep the information in mindb. change the quantity of informationc. organize information like a computerd. remember how to find the information7. what is the effect of the internet according to sparrows research?a. we are using memory differently. b. we are becoming more intelligent. c. we have poorer memories than before. d. we need a better way to access information. 答案4. a5. c6. d7. acday school programsecondary students across toronto district school board(tdsb) are invited to take one or two e-learning courses on their day school timetable. students will remain on the roll at their day school. the on-line classroom provides an innovative, relevant and interactive learning environment. the courses and on-line classroom are provided by the ministry of education. these on-line courses:are taught by tdsb secondary school teachers;are part of the tdsb students timetable; and, appear on the students report upon completion. benefits of e-learninginclude:access to courses that may not be available at his or her tdsb school;using technology to provide students with current informatio
