题目内容

The treaty requires signed countries to restrict tobacco advertising, sponsorship and promotion, set new labeling and clean indoor air controls and strengthen legislation to clamp down on tobacco smuggling.
At the time of its unanimous adoption last May by WHO's 192 members, the agency warned that the annual death toll of 4.9 million, if left unchecked, could double by 2020.
The tobacco epidemic is still expanding, especially in developing countries where currently seven out of every 10 tobacco-related deaths occur, according to WHO. At current rates, the total number of tobacco users is expected to rise to 1.7 billion by 2025 from 1.3 billion now.
The European Community (EC) has also signed the treaty as a regional economic integration organization, while its member states sign and ratify the treaty individually.

听力原文： How to Avoid Foolish Opinions
To avoid the various foolish opinions to which mankind is prone, no superhuman genius is required. If the matter is one that can be settled by observation, make the observation yourself. Many matters, however, are less easily brought to the test of experience. If you have passionate convictions on many such matters, there are ways in which you can make yourself aware of your own bias.
If an opinion contrary to your own makes you angry, that is a sign that you are subconsciously aware of having no good reason for thinking as you do. So whenever you find yourself getting angry about a difference of opinion, be on your guard; you will probably find that your belief is going beyond what the evidence warrants. A good way of ridding yourself of certain kinds of prejudice is to become aware of opinions held in social circles different from your own.
