[单项选择]
The U.S. Supreme Court’s decision Monday to let stand a ruling in an online defamation case will make it more difficult to determine correct legal jurisdictions in other Internet cases, legal experts said.
By opting not to take the case, the high court effectively endorsed a lower court’s decision that a Colorado company that posts ratings of health plans on the Internet could be sued for defamation in a Washington court. The lower court ruling is one of several that makes it easier for plaintiffs to sue Web site operators in their own jurisdictions, rather than where the operators maintain a physical presence.
The case involved a defamation suit filed by Chehalis, Wash.-based Northwest Healthcare Alliance against Lakewood, Colo.-based Healthgrades. com The Alliance sued in Washington federal court after Healthgrades. com posted a negative ranking of Northwest Healthcare’s home health services on the Internet.

If you left your book on the table overnight, you would find the following morning that it was still exactly where you had left it, provided nobody had moved it. If a ball is made to roll on a very smooth surface, it will roll a long distance unless something stops it or changes its direction. This tendency of an object to remain at rest unless something moves it and to continue moving unless something stops it is known as the Law of Inertia.
The following examples show the truth of this law.

[单项选择] Mrs. White
I hate salesmen. I mean they are always pestering me to buy things I don’t want. Why should I waste my time listening to their lies and looking at the junk they are trying to sell me When I need something, I go out and buy it. Things are cheaper at the supermarket and there’s a much better selection there.
Mrs. Lee
People prefer to buy from door-to-door salesmen because they are so friendly. A good salesman always brings things like candies for the children, sympathy for the tired housewife and a smile for the lonely old people. And the customers always have a chance to try things before they actually buy them. You don’t get that kind of service at the supermarket.
Mrs. Ros
I just don’t trust those salesmen. Once you let in a salesperson you can never get rid of him. They just keep talking and talking until you buy his goods. When you come to use the thing, you find out it’s a piece of junk. But you can’t get your money back. T
