Shopping is not as simple as you may think! There are all sorts of tricks at play each time we reach out for that particular brand of product on the shelf.

Colouring, for example, varies according to what the producers are trying to sell. Health foods are packaged in greens, yellows or browns because we think of these as healthy colours. Ice cream packets are often blue and expensive goods, like chocolates, are gold or silver.

When some kind of pain killer was brought out recently, researchers found that the colours turned the customers off because they made the product look weak and ineffective. Eventually, it came on the market in a dark blue and white package—blue because we think of it as safe, and white as calm.

The size of a product can attract a shopper. But quite often a bottle doesn’t contain as much as it appears to.

It is believed that the better-known companies spend, on average, 70 percent of the total cost of the product itself on packaging!

The most successful producers know that it’s not enough to have a good product. The founder of Pears soap, who for 25 years has used pretty little girls to promote (推销) their goods, came to the conclusion: “Any fool can make soap, but it takes a genius to sell it.”

     The island nation of Tuvalu (图瓦卢) in the Pacific Ocean wants the bigger countries of the world to do

something about climate change. And it's not just for the good of the planet: Tuvalu could be covered by the

sea in less than 50 years if the planet gets much hotter.

     Tuvalu has no industry, burns little petrol, and creates less carbon pollution than a small town in America.

However, this tiny place is on the front line of climate change. The increase in ocean temperatures and the

rising sea level -all resulted from a warming atmosphere-are making trouble for Tuvalu.

     Sea level rise is the greatest problem. With an average elevation (高度) of 6 feet above sea level, Tuvalu

doesn't have far to go. Tuvalu's highest elevation is 4.6 meters-15 feet-but most of it is no more than a meter

above the sea. Several times each year the regular lunar cycle of tides (潮水), riding on the ever higher sea

level, brings the Pacific waters over onto roads and into neighborhoods. Sometimes a high tide can flood roads

and run across the whole land. You can never separate the sea from the land, so some natives warned visitors,

"You'd better not run after dark, for you may fall into the sea."

1. What is the greatest problem Tuvalu is facing now? [ ]

A. It has no industry at all.

B. It has little petrol to burn.

C. It will sink into the sea in the near future.

D. The climate there has changed much.

2. Which of the following statements is NOT true? [ ]

A. Tuvalu is a small country.

B. Tuvalu doesn't create much carbon pollution.

C. Most of Tuvalu is no more than a meter above the sea.

D. A small town in America is on the front line of climate change.

3. What is the title of this passage? [ ]

A. Endangered Tuvalu

B. Tuvalu, an Island Nation

C. Flooded Tuvalu

D. Global Warming
