单选题{{B}}TEXT D{{/B}} Americans participated in a great debate throughout the 1960s and 1970s. The debate continues into the 1980s and 1990s. It is the argument over whether the use of the 150 million handguns, shotguns, and rifles in the United States should be restricted or banned altogether. And if so, how? Opinions on what should be done conflict sharply. Many Americans are confused by all that has been said. On the one hand, we hear that something must be done immediately to stop the havoc wrought by the gun. Statistics tell us that it is responsible for more than 30,000 murders, suicides, and accidental deaths each year. It is used in countless crimes and is said to either breed or reflect the violence that has become such a significant and frightening aspect of our national life. More than 20,000 Americans are murdered each year. Guns of all types--dries, shotguns, and handguns--are responsible for approximately 66 percent of these deaths. By itself, the handgun is responsible for more than 10,000 deaths. With an increasing number of lives being taken each year, there is a call to control the gun, to curtail its use and the ease with which it may be purchased in many parts of the country, or to be rid of it altogether. However, there are also many Americans who, despite the appalling death rate, feel that we have the right to own firearms. Opponents of strict gun controls argue that the right to own firearms is guaranteed by the U. S. Constitution. The claim is made that, without firearms, we would be more vulnerable than ever to criminal violence. Moreover, they claim, we would be unable to defend ourselves if subversive elements, a would-be dictator, or some foreign intruder attempted to take hold of the country. The privately owned gun helped us to win our freedom in the first place, they say; it can help us preserve that freedom today. Further, opponents of gun control tell us that gun-control laws don't work because the people who cause most of the trouble--the criminals--simply don't bother to obey them. But the proponents of control reply by producing statistics to show that control laws have kept the crime rates down in other nations. Strictly enforced controls, they believe, can do the same thing here.

More (31) than the number of tons of water is the amount of sea salt that was (32) in the reactors: ninety-nine thousand pounds (33) in reactors NO. 2 and 3, and fifty seven thousand in reactor No.1, according to the Times. (34) one might suppose, it is not good for any sort of (35) to have that much salt in it. During the Berlin Airlift, one of the biggest challenges was carrying salt into the city: no matter how it was (36) , it always seemed to get into and (37) the planes' engines. (And yet the city needed salt to survive. ) And it is not good for nuclear reactors; the heat and the way that it came in, on water, meant that it (38) and crystallized around the uranium fuel rods. From the Times: Crusts insulate the rods from the water and allow them to (39) up. If the crusts are thick enough, they can block water from (40) between the fuel rods. As the rods heat up, their zirconium cladding can rupture, (41) releases gaseous radioactive iodine inside and (42) even cause the uranium to melt and release much more radioactive material.

But it was an up-and-down day for the (48) at Fukushima Daiichi: two workers were injured when water, (49) with radiation, got into their boots. They are in the hospital now.
