[多选题]Few laws are so effective that you can see results just days after they take effect. But in the nine days since the federal cigarette tax more than doubled--to $1.01 per pack--smokers have jammed telephone "quit lines" across the country seeking to kick the habit. This is not a surprise to public health advocates. They've studied the effect of state tax increases for years, finding that smokers, especially teens, are price sensitive. Nor is it a shock to the industry, which fiercely fights every tax increase. The only wonder is that so many states insist on closing their ears to the message. Tobacco taxes improve public health, they raise money and most particularly, they deter people from taking up the habit as teens, which is when nearly all smokers are addicted. Yet the rate of taxation varies widely. In Manhattan, for instance, which has the highest tax in the nation, a pack of Marlboro Light Kings cost $10.06 at one drug store Wednesday. Charleston, S.C, where the 7-cent-a-pack tax is the lowest in the nation. The price was $4.78.The influence is obvious. In New York, high school smoking hit a new low in the latest surveys--13.8%, far below the national average. By comparison,26% of high school students smoke in Kentucky, Other low-tax states have similarly depressing teen-smoking records. Hal Rogers, Representative from Kentucky, like those who are against high tobacco taxes, argues that the burden of the tax falls on low-income Americans "who choose to smoke." That's true. But there is more reason in keeping future generations of low-income workers from getting hooked in the first place, as for today's adults, if the new tax drives them to quit, they will have more to spend on their families, cut their risk of cancer and heart disease and feel better. The text is mainly about_________.

[单选题]In spite of all stories of prosperity in the Unites States, not only does poverty exist there, but crimes of various types have been increasing at an alarming rate. Most acts of violence were committed by young people.57% of the criminals arrested in 1979 were youths below 25 of age. Everyone agrees that crime is partly a result of bad material conditions: poverty, lack of education, living within a settled home, being parent less, sufferings from other kinds of misfortune, etc. There are also other factors than material conditions which are responsible for the sharp increase of crime rate. In the first place, some state laws provide a death penalty but some not. Secondly, the Constitution allows every citizen to carry weapons for his own protection. It is therefore possible and easy for anyone in the country to get a gun. Finally, there has been too much shown on TV and too much reported in newspaper of all kinds of crime, the details of which are so accurately described that even children know how to duplicate what they have seen or read. All these have resulted in a high frequency of crimes committed both by professional criminals and by nonprofessional ones in murder, drug smuggling, robbery, etc. The author intends to tell the readers that_________.
[多选题]I've loved my mother's desk since I was just tall enough to see above the top of it as mother sat writing letters. Standing by her chair, looking at the ink bottle, pens, and white paper, I decided that the act of writing must be the more wonderful thing in the world. Years later, during her final illness, mother kept different things for my sister and brother."But the desk," she'd said again, "it's for Elizaheth." I never saw her angry, never saw her cry. I knew she loved me; she showed it in acdou. But as a young girl, I wanted heart-to-heart talks between mother and daughter. They never happened.And a gulf opened between us. I was "too emotional". But she lived "on the surface". As years passed I had my own family. I loved my mother and thanked her for our happy family. I wrote to her in careful words and asked her to let me know in any way she ebose that she did forgive me. I posted the letter and waited for her answer. None came. My hope turned to disappointment, then little interest and, finally, peace-it seemed that nothing happened. I couldn't be sure that the letter had even got to mother. I only knew that I had written it, and l could stop trying to make her into someone she was not. Now the present of her desk told, as she'd never been able to, that she was pleased that writing was my chosen work. I cleaned the desk carefully and found some papers inside--a photo of my father and a one-page letter, folded and refolded many times. Give me an answer, my letter asks, in any way you choose. Mother, you always chose the act that speaks louder than words. The word "gulf" in the passage means _______
