1.Advertising reaches people through varied forms of mass communication.These media include newspapers,magazines,television,radio and outdoor signs.Advertisers buy space in newspaper and magazine to publish their ads.They buy time on television and radio to broadcast their commercials.
One of the several advantages is that most adults read a daily newspaper,and many of them specifically check the ads for information about products,services ,or special sales.
A main advantage of television to advertisers is that it brings sight,sound and action directly to consumers in their home.And one advantage of advertising on radio is that people can listen to programmes while doing other things ,such as driving a car or working a car or working at home.
Magazines are usually read in a leisurely manner and are often kept for weeks or months before being discarded.While large,colorful outdoor signs,which people pass by repeatedly,easily attract attention.
Other ways of advertising include the use of transportation signs,window displays,point of sale displays ,telephone directories and novelties.

tpo17阅读第二篇第二题
Paragraph 2:In the varied and constantly changing light environment of the
forest,an animal must be able to send visual signals to members of its own
species and at the same time avoid being detected by predators.An animal can
hide from predators by choosing the light environment in which its pattern is
least visible.This may require moving to different parts of the forest at
different times of the day or under different weather conditions,or it may be
achieved by changing color according to the changing light conditions.Many
species of amphibians (frogs and toads) and reptiles (lizards and snakes) are
able to change their color patterns to camouflage themselves.Some also signal
by changing color.The chameleon lizard has the most striking ability to do
this.Some chameleon species can change from a rather dull appearance to a full
riot of carnival colors in seconds.By this means,they signal their level of
aggression or readiness to mate.
　　2.According to paragraph 2,what is
problematic about an animal's sending visual signals to members of its own
species?
○Signs that make an animal visible to its species also make it
visible to predators.
○An animal that changes color to avoid predators can
confuse members of its species.
○Changing light may require an animal to move
beyond the visual range of other members.
○The animal may mistakenly signal
aggression when it meant to signal readiness to mate
答案为什么选A啊,题中不是说要避免被捕食者发现么?
