Historian John Keegan writes: “Nuclear weapons have, since August 9, 1945, killed no one. The 50,000,000 who have died in war since that date have for the most part, been killed by cheap, mass-produced weapons and small ammunition, costing little more than the transistor radios which have flooded the world in the same period. Because small weapons have disrupted life very little in the advanced world, outside the restricted localities where drug-dealing and political terrorism flourish, the populations of the rich states have been slow to recognize the horror that this pollution has brought in its train.
Why have small arms become the weapons of choice in recent wars？ Part of the reason lies in the relationship between conflict and poverty. Most of the wars fought during the 1990s took place in countries that are poor----too poor to buy sophisticated weapon systems. Small arms and light weapons are a bargain. For example, 50 million dollars, which is approximately the cost of a single modern jet fighter, can equip an army with 200,000 assault rifles.
Another reason why small weapons are so popular is that they are lethal. A single rapid-fire assault rifle can fire hundreds of rounds a minute. They are also easy to use and maintain. A child of ten can be taught to strip and reassemble a typical assault rifle. A child can also quickly learn to aim and fire that rifle into a crowd of people.
The global traffic in guns is complex. The illegal trade of small arms is big. In some African wars, paramilitary groups have bought billions of dollars’ worth of small arms and light weapons, not with money, but with diamonds seized from diamond-mining areas.
Weapons are also linked to the illegal trade in drugs. It is not unusual for criminal organizations to use the same routes to smuggle drugs in one direction and to smuggle guns in the other.
11. It is implied in the passage that _____.
A、the nuclear arms-control talks can never reach an agreement
B、small arms-control is more important than nuclear arms-control
C、the power of nuclear weapons to kill people has been diminished
D、unclear weapons were the topic of arms-control talks 50 years ago
12. The advanced world neglect the problems of small arms because ____.
A、They have to deal with drug-dealing and political terrorism.
B、They have no such problems as are caused by small weapons.
C、They face other more important problems such as pollution.
D、They have not recognized the seriousness of the problems in time.
13. Which of the following is NOT mentioned as the reason for the prevalence of small arms？
A、Small arms are cheap.
B、Small arms are powerful.
C、Small arms are easier to use.
D、Small arms are easier to get.
14. We can conclude from the passage that _____.
A、small arms are not expensive in the black-market
B、it is unfair to exchange small arms for diamond
C、criminals use the same passage to smuggle drugs and small arms
D、where there are drugs, there are small arms
15. The best title for this passage is _____.
A、Small Arms Talks, Not Nuclear Arms Talks.
B、Neglect of Small Arms Control.
C、Global Traffic in Small Arms.
D、Small Arms, Big Problems.
Parenting is not an easy task. Becoming a parent is the easiest part, whereas, being a conscious and positive parent is a momentous task. Parenting is the most important role one faces in a lifetime. Parents who provide an encouraging environment for their children are rewarded when, as adults, their children realize a successful fit into the culture and society. Parenting concepts are deeply rooted in the majority of families in that country, because of a strong, sustained tradition of educating and training young parents to accept, perform. and establish enduring relationships and responsibilities with their children. Generally, the young mother is introduced to the nuances of parenting by way of the “hands on” method at her parental home, and under the guidance of her mother or an experienced family member. This practice could be the reason why the need for professional parent education usually is not expressed. Effective parenting enables children to build and develop positive behavior. and good, solid self-concepts that are important for functioning fully as a healthy adult. Parenting, as such, is greatly dependent on intra-familiar issues that play a significant role in parental performance. However, parenting skills can be strengthened if parents learn about themselves as a “parent” and about children’s development. Learning about the stages of human development helps parents understand about their ever changing roles in the lives of their children and also what is expected of a parent at each stage. Finally, a father’s love and influence is as important as a mother’s in the life of a child. Fathers should overcome the internal and external barriers that exist to fulfill the duties of fathering. According to the author, .
A、becoming a parent is a very difficult task
B、becoming a parent is an important task
C、parenting is a difficult and important task
D、parenting is an easy task
We could start with the advantages of mobile phones. There are many things that we could do with mobile phones. With the advancement of technology，more and more features are being added to the mobile phones which make them more useful. In addition to making calls，mobile phones also support a wide variety of other services such as text messaging，email，Internet access，business applications，gaming and photography. We can bring them everywhere，and can be reached by others anytime. They make the world smaller，bringing people together no matter where they are.
But we could have some risks when using our mobile phones. We may have accidents when we use them while driving. Some studies show that mobile phones can do harm to our bodies;and materials in mobile phones could damage our environment.
Since there are so many risks，why do we still have mobile phones？This is because these risks or disadvantages can be overcome. For example，while we are driving we can easily pull up our car if we really need to use the phone. Mobile phone manufacturers are reducing the radiation of mobile phones to avoid health risks.
Though there are both pros and cons of using mobile phones，we could easily see that there are more advantages than disadvantages. Moreover，mobile phones are becoming cheaper，which might be another reason why mobile phones are increasingly used today.

According to the majority of Americans, women are every bit as capable of being good political leaders as men. The same can be said of their ability to dominate the corporate boardroom. And according to a new Pew Research Center survey on women and leadership, most Americans find women indistinguishable from men on key leadership traits such as intelligence and capacity for innovation, with many saying they’re stronger than men in terms of being passionate and organized leaders. So why, then, are women in short supply at the top of government and business in the United States？ According to the public, at least, it’s not that they lack toughness, management talent or proper skill sets. It’s also not all about work-life balance.Although economic research and previous survey findings have shown that career interruptions related to motherhood may make it harder for women to advance in their careers and compete for top executive jobs, relatively few adults in the recent survey point to this as a key barrier for women seeking leadership roles. Only about one-in-five say women’s family responsibilities are a major reason why there aren’t more females in top leadership positions in business and politics. Instead, topping the list of reasons, about four-in-ten Americans point to a double standard for women seeking to climb to the highest levels of either politics or business, where they have to do more than their male counterparts to prove themselves. Similar shares say the electorate (选民) and corporate America are just not ready to put more women in top leadership positions. As a result, the public is divided about whether the imbalance in corporate America will change in the foreseeable future, even though women have made major advances in the workplace. While 53% believe men will continue to hold more top executive positions in business in the future, 44% say it’s only a matter of time before as many women are in top executive positions as men. Americans are less doubtful when it comes to politics: 73% expect to see a female president in their lifetime. （2019.6月四级真题） Q: What do we learn from previous survey findings about women seeking leadership roles？
A、They have unconquerable difficulties on their way to success.
B、They are lacking in confidence when competing with men.
C、Their failures may have something to do with family duties.
D、Relatively few are hindered in their career advancement.
The original Americans, of course were the Indians.The so-called white men who then came were mostly from England.But many came from other countries like Germany and France.
One problem the United States has always had is discrimination.As new groups came to the United States, they found they were discriminated against.First it was the Irish and Italians.Later it was the blacks.Almost every group has been able to finally escape this discrimination.The only immigrants who have not are the blacks.Surprisingly enough the worst discrimination today is shown towards the Indians.
One reason the Indians are discriminated against is that they have tried so hard to keep their identity.Of course they are not the only ones who have done so.The Japanese have their Little Tokyo in Los Angeles and the Chinese a Chinatown in New York.The Dutchsettlement in Pennsylvania also stays separate from other people.Their towns are like something from the 19th century, They have a different reason from the other groups for staying separately.They live separately for religious reasons rather than keep together in a racial group.
Although some groups have kept themselves separate and others have been discriminated against, all groups have helped make the United States a great country.There is no group that has not helped in some way.And there is no group that can say they have done the most to make it a great country.
Many people still come from other countries to help the United States grow.A good example is the American project that let a man walk on the moon.It was a scientist from Germany who was most responsible for doing that.It is certain that in the future the United States will still need the help of people from all racial groups to remain a great country.

I’m like a migratory bird that has lost its sense of timing and direction, my wings flapping against season.
So what makes me fly against the tide of snowbirds？ The answer has a lot to do with my reluctance to give up the things that define who I am. Once I hear that the temperature on Long Island has dipped into the range of 40 to 50 degrees, I begin to long for the sight and crackling sound of a wood fire. I also long for the bright display o£ colors — first in the fall trees, and then in the limits around homes and at Rockefeller Center. Floridians decorate too, but can’t create the special feel of a New England winter.
I suppose the biggest reason why I return is to celebrate the holidays with people I haven’t seen in months. What could be better than sitting with family and friends for a Thanksgiving turkey dinner, or watching neighbors’ children excitedly open gifts on Christmas？ Even the first snowfall seems special. I especially enjoy seeing a bright red bird settling on a snow-covered branch (My wife and I spend winters at a retirement community in Ridge, and I’m grateful that I don’t have to shovel.)
While these simple pleasures are not unique to Long Island, they are some of the reasons why I come back. Who says you can’t go home？
