Passage Four

Despite their names, satin and soman are exceptionally ugly sisters. They are organophosphorous nerve gases. They are cheap and simple to manufacture. And mere milligrams—just a drop—of either is enough to kill an adult in a couple of minutes. They therefore make particularly fine weapons of mass destruction, equally popular with rogue dictators who have not been able to build nuclear bombs and with weird cults such as Aum Shinrikyo, which gassed the Tokyo subway in 1995.
Detecting them soon enough to prevent their effects can be difficult. Even detecting them after the event—if you are, for example, a United Nations weapon inspector—can be haphazard.

[单项选择]Passage Four Despite the numerous warnings about extreme weather, rising sea levels and mass extinctions, one message seems to have got lost in the debate about the impact of climate change. A warmer world won’t just be inconvenient. Huge swathes (片) of it, including most of Europe, the US and Australia as well as all of Africa and China will actually be uninhabitable--- too hot, dry or stormy to sustain a human population. This is no mirage. It could materialize if the world warms by an average of just 4°C, which some models predict could happen as soon as 2050. This is the world our children and grandchildren are going to have to live in. So what are we going to do about it One option is to start planning to move the at-risk human population to parts of the world where it will still be cool and wet.

[单项选择]Passage 2

There are four basic types of competition in business that form a continuum from pure competition through monopolistic competition and oligopoly (商品供应垄断) to monopoly. At one end of the continuum, pure competition results when every company has a similar product. Companies that deal in commodities such as wheat or corn are often involved in pure competition. In pure competition, it is often the ease and efficiency of distribution that influences purchase.
In contrast, in monopolistic competition, several companies may compete for the sale of items that may be substituted. The classic example of monopolistic competition is coffee and tea. If the price of one is perceived as too high, consumers may begin to purchase the other. Coupons and other discounts (折扣) are often used as part of a marketing strategy to influence sales.
Olig
A. permitted
B. reserved
C. criticized
D. devised

[单项选择]Passage Three

Despite efforts to provide them with alternatives such as the shelter, women frequently and repeatedly returned to violent and abusive partners. By the late 1970s, feminists at Women Together, like those doing similar work throughout the United States, began to understand that battered women experience a range of post-traumatic psychological responses to abuse, similar to those of victims of other types of violence or trauma. Subsequently, the psychological response of battered women became reified as "battered woman syndrome," a sub-category of post-traumatic stress disorder. Interestingly, in the course of trying to create social change, the focus of feminists perceptibly shifted to trying to explain why battered women fail to leave the partners who beat them. In trying to address this question, a debate ensued among feminists a
