Part III Reading ComprehensionSection ADirections： In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank before the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. You may not use any of the words in the bank more than once.For most people, shopping is still a matter of wandering down the high street or loading a cart in a shopping mall. Soon, that will change. Electronic commerce is growing fast and will soon bring people more choice. There will, however, be a cost: (1)the consumer from fraud will be harder.

For instance, customers ordering medicines online may prefer to buy from the United States because they trust the rigorous screening of the Food and Drug Administration; or they may decide that the FDA's rules are too strict, and buy from Switzerland instead.Consumers will need to use their judgment. But precisely because the technology is new, (9)shoppers are likely for a while to be a lot more cautious than consumers of the normal sort—and the new technology will also make it easier for them to complain noisily when a company lets them down.
