What would I have to bring？ W: Let's see. Tom's bringing food for the Friday night cookout for everyone.

To get a hand in is to begin a job, to begin to know something about it. When we learned completely, it will be easy for us. We will be able to do it hands down. If we do the job well, we may end up with the upper hand. That means to be in control or to have gained complete understanding of a situation. On the other hand, if the situation gets out of hand then, it is out of control. Then we may have to hand it to someone, to let someone else take over the business. It is time for us to wash our hands, to end it up completely. You can also lend a hand to someone but without really giving up your hand. You lend a hand when you help someone. You offer them a helping hand. If someone is kind enough to lend us a hand then we surely do not want to bite the hand that feeds us. We do not want to repay his kindness by treating him badly.

The storm killed two other people in Alabama, nine in the neighboring state of Georgia, and a young girl in Missouri. Fourteen teams of experts from the Federal Emergency Management Agency are evaluating the damage to assess what federal assistance might be needed in situations that overwhelm state and local capabilities. That agency and President Bush were widely criticized for their poor response to Hurricane Katrina in August of 2005, which killed more than 1,800 people along the Gulf Coast. Asked if the president's decision to visit the tornado-stricken areas Saturday was influenced by the political fall-out from Hurricane Katrina, White House Spokeswoman Dana Perino said that was never part of the discussion. Traveling with the president, FEMA Director David Paulson stressed how much the response system has changed since Hurricane Katrina, telling reporters that federal officials no longer wait for state and local governments to be overwhelmed before stepping in. Why are 14 teams of experts from the Federal Emergency Management Agency evaluating the damage？ A．To find out the lost people and animals. B．To criticize the authority's poor response. C．To assess the federal assistance needed. D．To make clear the investment in agriculture.

Woman: Thank you, Chris. You know, today—with so many Americans counting calories and wanting to eat more natural foods—there are many new kinds of bread on supermarket shelves, high fiber bread, wheat germ bread, low calorie bread, to name only a few. Well, despite the variety, the principal ingredients of bread have remained the same. flour, water, and yeast. There may be a few other things added as food for the yeast to help it develop or as agents to assist the baking process, but these additives appear in minute quantities and have little effect on calories or nutrition. Man: Well, what about the differences between white bread and whole grain bread, Alice？ Is whole grain bread really superior nutritionally？ Woman: Both have their advantages, Chris. Whole grain bread does have more fibers of course, and the bulk which the fiber provides can be useful in digestion. White bread has a finer texture. The reason that so many people feel white bread is nutritionally lacking is the bleaching process. Bleaching, which gives bread its distinctive white color, does remove many nutrients. But what many people are unaware of is that these nutrients are added back into the bread after the bleaching process. And this re-adding process has a distinct advantage for some people. One nutrient that is re-added, iron, is unbounded in white bread whereas the iron which is retained in its natural state in whole grain bread is bonded to other chemical constituents. Studies have shown that some people have difficulty absorbing the bonded iron but can readily absorb the unbounded iron in bleached white bread. Probably the soundest advice for most people is to eat some of both types of bread. And now here's a story which makes the good old days seem that much further in the past. Do you still remember the nickel candy bar that you used to buy on the way home from school when you were a child？ Well, after successive increases to 10, 15, and 20 cents, the old nickel candy bar is now going to cost you a quarter. Candy manufacturers report that the bars will be larger. But, whereas the price is increasing 25%, the average weight increase for a bar is only 14%. Man：Thank you, Alice. We'll have more news after we return from a commercial break. 19.According to the report, what are the three main ingredients found in bread？ 20.What advantage does unbounded iron offer？ 21.Which of the following statements about bread is true？ 22.What gives white bread its distinctive color？ (39) A．Fiber, wheat germ and water. B．Iron, flour and yeast. C．Yeast, flour and fiber. D．Flour, water and yeast.

M: I think so. It’ll be especially helpful if you can check the same story in the newspaper. Q: What does the man mean？ (18) A．Watching TV is better than reading a newspaper.

M: Well, of course it is an increasingly serious problem, I mean a fairly large part of the old population becomes confined to the house.

Q: What are the speakers talking about？ (17) A．Population explosion. B．Generation Gap. C．Problem of the aged. D．Climate changes.

M: Well, the 1992 Maastricht Treaty proposed a single currency between the European Union. The participating countries decided on the name "Euro' at a summit in Madrid in 1995 and the currency was launched on January 1, 1999. W: What is it worth？ M: When the Euro was launched in 1999, one Euro was worth 1.17 US dollars or 71 British pence. However, the weakness of the Euro zone economies compared with that of the United States, combined with the inexperience of the European Central Bank in dealing with the international markets, has meant that since its launch the value of the Euro had declined significantly. In December 2001, one Euro was worth little more than 89 cents or 63 pennies, a 20 percent drop on its initial value. W: Do you think it will affect the daily life of ordinary people？ M: I suppose so. For example, one of the major headaches for participating countries has been the con version of public telephones, vending machines, and shopping trolleys to accept Euro coins. Al though a conversion process has been in full swing since before 1999, there are reports that some countries are not ready for the Euro. W: So what does it look like？ M: There are seven notes designed by the Austrian artist Robert Kalina. The designs show the "seven ages" of European development, with windows and gateways on the front, and bridges on the back. In addition, there are eight coins designed by the Belgian artist Luc Luycx. All Euro coins are round, but have differences in composition, weight, thickness, and milling to ensure that the blind can easily distinguish between them. On the front there is a European design, common to all coins, and on the back a "national" design from the central bank of issue. Despite the "national identities'', all coins can be spent throughout the Euro zone regardless of their origin. (36) A．1992 B．1995 C．1999 D．2001

W: At least. It used to be my most favorite song before ! had to hear it so often. Q: What did the two speakers say about Mike's album？ (18) A．It's their most favorite album.

M: I'd be happy to. The piece that broke off was over a thousand square miles in area. More recently and quite alarming to scientists is that a forty-mile crack, some 30 feet wide in places has torn through the ice shelf. W: I understand that the scientific community is quite concerned. What is the significance of these events？ M: Well, some scientists believe that this is a clear sign of global warming. Back in 1978, some American researchers predicted that Antarctica would show early signs of global warming due to the green house effect. W: But couldn't crumbling ice shelves also be a result of the unusual weather Antarctica itself has experienced lately？ M: That's certainly possible, but you'll have to remember that over the past thousands of years, ice shelves have been through a lot of weather changes without breaking up. W: I think most people know that if the ice cap over Antarctica melts, the level of the oceans will rise. What sort of impact will this have？ M: Well, the ice shelves currently insulate the Antarctic continent from wind, which slows down the melting. If the winds cause even a tenth of the continent's ice to melt, the world's oceans could rise as much as 30 feet. What are the speakers mainly discussing？ A．An experiment in Antarctica. B．Part of the Larsen Ice Shelf broke off. C．The formation of the Larsen Ice Shelf. D．An expedition in Antarctica.
