Maybe some of you drink hot tea with lemon when you have a cold.Yes?No?OK, for tho who don't know about hot tea with lemon it's just a common tea.But do you know weather it's effective?Of cau you e lots of advertiments saying it is that they wouldn't ll much if they don't, would they?So how can we be sure ?The following example experiment will help you find out.First of all, we should find some participants who have get a coold and haven't accept any remedy.We divided them into two groups, the experimental group and the controlled group.Participants in the experimental group we give them the hot tea of lemon while the controlled group we just give them a placebo, which looks like the experimental treatment but does nothing.At the same time, all the participants are not allowed to know which group they are in to make sure the experiments are blind experiments.Then if there is a difference between the two groups, maybe, just maybe, the difference is from taking hot tea of lemon.So the controlled group is the same as the experiment group but doesn't get the experimental treatment.玩用英语怎么说
2.Think about the lecture, “New Ways in Advertising.” It describes two marketing strategies—viral marketing and stealth marketing.
Now read the list of products below. Consider which marketing strategy would work best for each product. Why do you think it is the best strategy? How would you adverti the product? What are the advantages and disadvantages of the strategy you cho?
a cell phone with camera
雅思听力标准a luxury hotel
a computer game for young adults
a popular dance club
Choo one product and briefly explain the best marketing strategy for the product, why you think it is the best strategy, how you would adverti the product, and
possible advantages and disadvantages of the strategy you cho. Talk about your points and record it, then upload your record on the internet.
The product I choo to talk about how to adverti is a computer game for young adults.As we all know, advertiments are aimed at getting the most notice of people and
getting the companies' message across.Thus we should get the advertiment into the right place at the right time for the right people to e them.As for a computer game for young adults, the best marketing strategy must be the advertiment placed on the Internet at all time for the young adults. I argue that the best marketing strategy is stealth marketing for the reason that it is effective but not expensive.We can give T-shirts to teenagers as young as 13.In exchange, the teenagers may agree to talk to their friends at shcool and on Internet chat sites about the game that our company is marketing.But there may exists certain disadvantages, though it spreads from person to person by word of mouth, adults are limited to tell the name of the company.So once their parents find that they may get angry becau they feel they have been tricked.
3.riting a paragraph about the following topic:
Think about the lecture, “Are Asteroids and Comets Dangerous?” It discuss the likelihood of asteroid collisions. Do you think we should be concerned about a large object striking Earth and causing a catastrophic event?
西兰花炒虾
We’re all aware that one of the ways that human life on Earth could end, conceivably, is the same way that the dinosaurs went down. And asteroid tracking and deflection technology is fast becoming one of the hot issues of the day. It appears so often in the news that we’d think we are at a high risk, any day, of being hit by a catastrophic asteroid. But — and my opinion here definitely runs against the mainstream — I think this hysteria is absolutely ridiculous. One of the things you almost never hear about are the frequency and the odds of an asteroid strike harming us. If large asteroid strikes happened every few decades, we’d have something legitimate to prepare for and worry about. But if we’ve only got a one-in-a-million chance of an asteroid harming us over our lifetime — meaning we are over 100 times more likely to be struck by lightning than harmed by an asteroid — perhaps there are better ways to spend our resources.
