Over the last few decades, the United States steel industry has become less concentrated.

The United States government publishes guidelines for appropriate nutrient intakes. These are known as the Recommended Dietary Allowances (RDAs) and are updated regularly based on new research in nutrition. RDAs are suggested amounts of calories, protein, and some minerals and vitamins for an adequate diet. For other dietary substances, specific goals must await further research. However, for the U.S. population as a whole, increasing starch and fiber in one's diet and reducing calories (primarily from fats, sugar, and alcohol) is sensible. These suggestions are especially appropriate for people who have other factors-for chronic diseases due to family history of obesity, premature heart disease, diabetes, high blood pressure, and high blood cholesterol, or for those who use tobacco.

Snacks can furnish about one-fourth of the calorie requirements among teenagers. Those snacks should also provide much of the day's allowances for protein, minerals, and vitamins. Sandwiches, fruit, and milk make good snacks for active teenagers. Food from the food pyramid may be part of any meal. A grilled cheese sandwich or a bowl of whole-grain cereal is just as nutritious in the morning as it is at noon. In addition, a good breakfast consists of any foods that supply about one-fourth of the necessary nutrients for the day.

The passage directly states that most of the U.S. population should increase their intake of ______.

A．protein

B．fats

C．starch and fiber

D．sandwiches

Parents have to do much less for their children than they used to do, and home has become much less of a workshop. Clothes can be bought ready made; washing can be done at the laundry; food can be bought cooked, canned; bread is baked and delivered by the baker; milk arrives on the doorstep; meal can be had at the restaurant, the work's canteen, and the school dining room.

It's unusual now for father to persue(追求)his trade of other employment at home, and his children rarely, if ever, see him at his place of work. Boys are therefore seldom trained to follow their father's business, and in many towns they have a fairly wide choice of employment and so do girls. The young wage-earner often earns good money, and soon gains a feeling of economic independence (经济上的独立). In textile areas it has been customary for mothers to go out to work, but this practice has become so widespread that the working mother is now not an unusual factor in a child's home life, the number of married women in employment having more than doubled in the last twenty five years. With mother earning and older children drawing wages, father is seldom the most important figure that he still was at the beginning of the century. When mother works, economic advantages increase, but children lose something of great value if mother's employment prevents her from being home to greet them when they return from School.

The writer compares home to a workshop because ______.

A．fathers often persue employment at home

B．many families produce goods at home for sale

C．both fathers and mothers in most families are workers

D．parents have to make food and necessity themselves for their daily life

The issue of climate change is now very, very critical indeed. Let me try and explain to you frankly what I see, from the policy-makers point of view, as the two difficulties we've got to overcome and how we overcome them. //

The first is that I think there is a clear recognition round the world now that something is happening to our climate—people are experiencing it and feeling it. Nonetheless, the timeframe. over which some of these things are going to impact is certainly beyond any very short-term political cycle, and often stretches significantly into the future. That's one issue. //

And the other issue is that there has grown up round the world, a debate, that sometimes I think takes place on a quite false basis but nonetheless is there, that somehow there is a trade-off between economic growth and environmental protection, so that if we improve the protection of our environment, we may inhibit our ability to grow and to enjoy rising living standards. //

Now each of these two issues has to be confronted. How do we do that, is the real question. The first is how do we get the world to think long-term about this? We have to continue to build a very strong base of support and agitation for change, not just in the political world but in civic society as well. I think that is enormously important, the pressure on this has got to come on governments from people, not merely on governments from their own internal mechanisms. //

We are committed to the Kyoto Protocol. We believe it is essential that we have that implemented. We in our country will abide by our Kyoto targets, but I just want to make one point to you. When I asked for an analysis to be done by David King and his colleagues of what the true scale of the challenge was, we learned that even if we were to implement the Kyoto Protocol, it falls significantly short of what we will need over the next half century if we are to tackle this problem seriously and properly. //

So even, and this is a tall order in some ways at the moment, if we succeed in getting support for the Kyoto Protocol, we are still, even having done that, only in the position of having achieved a first step. It will be an important recognition, but it is only a first step and we need to be building a clearer understanding of the fact that even with Kyoto we are still a long way short of what we actually need to do. And we've got to build support in the political institutions of which we're a part in order to make sure that case is properly understood. //

I think we have to make sure that this occupies, as an issue, a central place in political decision-making beyond any election or parliamentary cycle. It's beyond the life of any government. It's beyond the life of any passing political phase. It has to be there, central in the politics of each country, built up not just from support within government, but from support within civic society over a period of time. //

The second point is about the conflict between the supposition that we need to grow continually and that we cannot grow unless we degrade our environment. That is the importance of a Climate Group that involves not just states and cities but also business so that there are practical, clear examples of how good environmental policy is also good business policy and is right for growth. If you look in the 12 years 1990 to 2002, we in Britain cut our emissions by about 15 percent whilst we were growing at 30 percent. It is possible to do. //

Showing that cities and states and businesses can do good environmental policy and actually reap an economic benefit is enormously important because that debate about some supposed trade- off between environmental protection and economic growth is still there. We may all, in this room, believe that that argument has been resolved long ago, but I can tell you there is
