Strangely, the more we are exposed to advertising, the less we notice it. We get so used to seeing advertisements everywhere that they become largely invisible, as if they were another part of our everyday lives. But does that mean that we are no longer affected by them?
One advertising expert believes that the special power of advertising lies in the fact that we do not pay much attention to it. Dr. Krugman, who was head of research for a major advertising company for many years, says that the less we notice ads, the more we are affected by them. Dr. Krugman believes that when we stop noticing advertisements, we lower our defenses, allowing the messages of the advertisements to be taken in and stored, ready to be triggered into action at the right moment. He says that the effects of advertising on the individual are small, but over a period of time they have a powerful effect on the masses.
A market analyst says that all advertising, no matter how innocent, is misleading in some way.
When asked about the power of advertising in research surveys, most people agree that it works, but not on them. Almost everyone believes that they have complete control over how thousands of ads they see every day affect them.
Ads exist to make people want______.
A．a new type of orange juice
B．X-brand jeans
C．to watch the latest film
D．what they advertise
Even as the U.S. Senate debates a vast new tax and spend regime in the name of fighting climate change, a more instructive argument was taking place in Copenhagen, Denmark. Some of the world's leading economists met earlier this month to decide how to do the most good in a world of finite resources.
Scarcity is a core economic concept. There isn't an unlimited amount of money to be spent on every problem, so choices have to be made. The question addressed by the Copenhagen Consensus Center is what investments would do the most good for the most people. The center's blue-ribbon panel of economists, including five Nobel laureates, weighed more than 40 proposals to improve the world by spending a total of $75 billion over the next four years.
What would do the most good most economically？ Supplements of vitamin A and zinc for malnourished children.
Number two？ A successful outcome to the Doha Round of global flee-trade talks.
Global warming mitigation？ It ranked 30th, or last, right behind global warming mitigation research and development.
On the benefits of freer trade, it was estimated that a successful Doha Round could generate up to $113 trillion in new wealth during the 21st century, at a cost of $420 billion or less from inefficient industries going bust.
Meanwhile, providing vitamin A and zinc would help some 112 million children in sub-Saharan Africa and South Asia for merely $60 million a year. The minerals would help prevent blindness and stunted growth—increasing lifetime productivity by an estimated $1 billion. Similar if not quite so bountiful returns apply to investments in iron supplements, salt iodization and deworming, all low-cost measures that the economists in Copenhagen ranked highly.
Read the passage carefully and answer three questions. Learning styles We all learn in different ways. One theory of learning focuses on the way information is given to learners and refers to visual, auditory and kinaesthetic learners. • Visual learners respond well to pictures, colours, images. They need to see things to help them learn and remember. • Auditory learners learn best by hearing things. • Kinaesthetic learners like movement. They need movement and hands-on tasks to help them learn. In any class we teach, the learners will have a range of learning styles. This means that to help all of our learners learn we have to use a range of classroom activities and techniques so that different styles of learner are interested and can learn from our lessons.
