Ads sometimes help people learn more about new products, but at other times ads tell lies． [ ] A．must B．can C．need D．should 题目和参考答案——青夏教育精英家教网—

    Never go into a supermarket hungry! This is a good piece of advice. If you go shopping for food before
lunchtime, you'll probably buy more than you plan to. Unfortunately, however, just this advice isn't enough
for consumers these days. Modern shoppers need an education in how and how not to but things at the
store. First, you check the weekly newspaper ads. Find out the items that are on sale and decide if you really
need these things. In other words, don't but anything just because it's cheaper than usual! "New and
Improved!" or "All Natural" on the front of a package influence you. Instead, read the list of ingredients
(成分) on the back. Third, compare prices: that is, you should examine the prices of both different brands
and different sizes of the same brand.
    Another suggestion for customers is to buy ordinary items instead of famous brands. Ordinary items in
supermarkets come in plain packages. These products are cheaper because producers don't spend much
money on packing or advertising. The quality, however, is usually as good as the quality of well-known
name brands. In the same way, in buying clothes, you often find high quality and low pices in brands that
are not famous. Shopping on discount clothing stores can help you save a lot of money. Although these
stores aren't very attractive, and they usually do not have individual dressing rooms, not only are the prices
low, but you can often find the same famous brands that you find in high-priced department stores.
    Wise consumers read magazine ads and watch TV commercials, but they do this with one advantage:
knowledge of the psychology behind the ads. In other words, well-informed consumers watch for information
and heck for misinformation. They ask themselves questions: Is the advertiser hiding something in small print
at the bottom of the page? Is there any real information in the commercial, or is the advertiser simply showing
an attractive image? With the answers to these questions, consumers can make a wise choice.
