Drive through any suburb in the U.S. Today, and it’s hard to miss the recycling bins that have become companions to America’s trash cans. Recycling has become common, as people recognize the need to care for the environment. Yet most people’s recycling consciousness extends only as far as paper, bottles, and cans. People seldom find themselves facing the growing problem of e-waste.

E-waste rapidly increases as the techno- fashionable frequently upgrade to the most advanced devices, and the majority of them end up in landfills (垃圾填埋地). Some people who track such waste say that users throw away nearly 2 million tons of TVs, VCRs, computers, cell phones, and other electronics every year. Unless we can find a safe replacement, this e-waste may get into the ground and poison the water with dangerous toxins (毒素), such as lead, mercury, and arsenic. Burning the waste also dangerously contaminates the air.

However, e-waste often contains reusable silver, gold, and other electrical materials. Recycling these materials reduces environmental problems by reducing both landfill waste and the need to look for such metals, which can destroy ecosystems.

A growing number of states have adopted laws to ban dumping e-waste. Still, less than a quarter of this waste will reach lawful recycling programs. Some companies advertising safe disposal in fact merely ship the waste to some developing countries, where it still ends up in landfills. These organizations prevent progress by unsafely disposing of waste in an out- of- sight, out- of- mind location.

However, the small but growing number of cities and corporations that do handle e- waste responsibly represents progress toward making the world a cleaner, better place for us all.

1.What can we infer from the first paragraph?

A. Many Americans now have access to recycling bins.

B. E-waste cannot be put into trash cans in the U.S.

C. Most Americans have realized the dangers of e-waste.

D. Most of America’s trash cans are made of recycled material.

2.What can best replace the underlined word “contaminates” in Paragraph 2?

A. pollutes.　　 B. heats.

C. absorbs.　　 D. reduces.

3.How does the author feel about burying e-waste in landfills?

A. It’s important.　　 B. It’s unsafe.

C. It’s acceptable.　　 D. It’s uncommon.

4.What’s the author’s purpose in writing this text?

A. To tell us how to recycle e-waste.

B. To talk about the future of e-waste.

C. To discuss if it’s necessary to recycle e-waste.

D. To encourage us to deal with e-waste properly.

The 2009 outbreak of HINI is a new kind of influenza virus, commonly referred to as “swine flu”. It is thought to be a break of four known kinds of influenza. A virus subtype H1N1: one endedmic(流行病) in humans, one endemic in birds, and two endemic in pigs (swine). The source of the outbreak in humans is still unknown, but cases were first discovered in the U.S. and soon after in Mexico.

According to the U.S. Centers for Disease Control and Prevention(CDC)，it is not yet clear how serious this new virus actually is compared with other influenza viruses, although on May 26 they stated that new cases in the U.S. have probably reached the hightest point, and most cases have so far been mild relative to “seasonal flus”. But because this is a new virus, most people will not have immunity(免疫性) to it, and illness may eventually become more severe and widspread. The H1N1 flu mainly spreads in the same way that regular “seasonal influenza” spreads through the air from coughs and sneezes or touching those infected. It cannot be transmitted from eating cooked pork or by being in close contact with pigs.

As yet there is no vaccine(疫苗) available to prevent infection although companies are in the planning stages for having one available later this year. But there is concern that the virus could vary again over the coming months, leading to a new and potentially more dangerous flu outbreak later in the year, and a vaccine that will be less effective in preventing its spread.

As of May 27, the virus had spread to more than 50 countries; however, over 80% of reported deaths have taken place in Mexico. According to the CDC, the fact that the flu’s infection activity is now monitored more closely may help explain why more flu cases than normal are being recorded in Mexico, the United States and other countries.

1.The 2009 outbreak of H1N1 is thought to ________.

A.be concerned with four endmics

B.have come from the virus from pigs

C.occur because of unknown virus in Mexico

D.be caused because of people without immunity

2.According to the U.S. Centers for Disease Control and Prevention, ______.

3.To make people worried more is that ________.

4.From the passage we can learn that ________.

A.every country is watching closely the spreading of the H1N1

B.more than one-fourth of the deaths from the H1N1 are in Mexico

C.only the United States and Mexico recorded the cased of influenza

D.effective medicine has been produced to cure the H1N1

The term bystander effect refers to the phenomenon in which the greater the number of people present, the less likely people are to help a person in distress. When an emergency situation occurs, observers are more likely to take action if there are few or no other witnesses. Being part of a large crowd makes it so no single person has to take responsibility for an action (or inaction).

The most frequently cited example of the bystander effect in introductory psychology textbooks is the brutal murder of a young woman named Catherine "Kitty" Genovese. On Friday, March 13, 1964, 28-year-old Genovese was returning home from work. As she approached her apartment entrance, she was attacked and stabbed by a man later identified as Winston Moseley.

Despite Genovese’s repeated calls for help, none of the dozen or so people in the nearby apartment building who heard her cries called police to report the incident. The attack first began at 3:20 AM, but it was not until 3:50 AM that someone first contacted police.

While Genovese's case has been subject to numerous misrepresentations and inaccuracies, there have been numerous other cases reported in recent years. The bystander effect can clearly have a powerful impact on the general conduct of people in a society, but why exactly does it happen? Why don't we help when we are part of a crowd?

There are several factors that contribute to the bystander effect. First, the presence of other people creates a diffusion of responsibility. Because there are other observers, individuals do not feel as much pressure to take action, since the responsibility to take action is thought to be shared among all of those present.

The second reason is the need to behave in correct and socially acceptable ways. When other observers fail to react, individuals often take this as a signal that a response is not needed or not appropriate. Other researchers have found that onlookers are less likely to intervene if the situation is ambiguous. In the case of Kitty Genovese, many of the 38 witnesses reported that they believed that they were witnessing a "lover's quarrel," and did not realize that the young woman was actually being murdered.

Characteristics of the situation can play a role. During a crisis, things are often chaotic and the situation is not always crystal clear. Onlookers might wonder exactly what is happening. During such chaotic moments, people often look to others in the group to determine what is appropriate. When people look at the crowd and see that no one else is reacting, it sends a signal that perhaps no action is needed.

So what can you do to avoid falling into this trap of inaction? Some psychologists suggest that simply being aware of this tendency is perhaps the greatest way to break the cycle. When faced with a situation that requires action, understanding how the bystander effect might be holding you back and consciously taking steps to overcome it can help. However, this does not mean you should place yourself in danger.

But what if you are the person in need of assistance? How can you inspire people to lend a hand? One often-recommended tactic is to single out one person from the crowd. Make eye contact and ask that individual specifically for help. By personalizing and individualizing your request, it becomes much harder for people to turn you down.
