Passage Four The U.S. Treasury Department has redesigned the $100 bill, and has begun releasing the new currency recently. Treasury Department spent nearly 10 years on the redesign and has added a number of state-of-the-art features: micro printing, color-shifting ink, a polymer(聚合物) security thread. The most striking change, however, is the enlargement of Benjamin Franklin’s portrait: he now dominates the bill like a movie star in a newspaper advertisement. The money we carry around is so familiar that whenever a new bill or coin is introduced, it creates a ripple(波动) in our ordinary lives. But not much more than a ripple, and since few people use $100 bills regularly, most Americans greet the arrival of the new note with no stronger emotion than curiosity. Some foreigners, by contrast, have become clearly worried by the news of its arrival. Around the world, U.S. currency-and the $100 bill in particular-is often treated as the ultimate repository(贮藏所) of value. The Federal Reserve estimates that two-thirds of all U.S. cash circulates outside the United States. In nations where inflation is high and where there are few credible banking institutions-from Latin America to Africa-people save and conduct business in $100 bills. And with the U.S. issuing new $100 bills, many abroad are worrying that the ones they already have are about to become worthless. The fear is most widespread in Russia. The Russian Central Bank estimates that somewhere between $15 billion and $20 billion of U.S. currency is in Russia, about 80% of it in the form of $100 bills. Everyone from small savers to businessmen to members of Mafia(黑手党) relies on hundreds, so the changes in the bill are causing high anxiety. Many Russians have already changed their meager(微不足道) supply of $100 bills into smaller U.S. notes. But over the next few years Treasury plans to redesign every note except the $1 bill. The fear of the new $100 bill is most widespread in those countries where ______
A. the economic situation is unstable
B. two-thirds of all U.S. cash circulates
C. the old $100 bills will become more valuable
D. there are too many old $100 bills circulating
Passage Three In the primary school, a child is in a comparatively simple setting and most of the time forms a relationship with one familiar teacher. On entering secondary school, a new world opens up and frequently it is a much more difficult world. The pupil soon learns to be less free in the way he speaks to teachers and even to his fellow pupils. He begins to lose gradually the free and easy ways of the primary school, for he senses the need for a more cautious approach in the secondary school where there are older pupils. Secondary staff and pupils suffer from the pressures of academic work and seem to have less time to stop and talk. Teachers with specialist roles may see hundreds of children in a week, and a pupil may be able to form relationships with very few of the staff. ①He has to decide which adults are approachable; good schools will make clear to every young person from the first year what guidance and personal help is available but whether the reality of life in the institution actually encourages requests for help is another matter. Adults often forget what a confusing picture school can offer to a child. He sees a great deal of movement, a great number of people-often rather frightening-looking people-and realizes that an increasing number of choices and decisions have to be made. As he progresses through the school the confusion may become less but the choices and decisions required will increase. ②The school will rightly expect the pupil to take the first steps to obtain the help he needs, for this is the pattern of adult life for which he has to be prepared, but all the time the opportunities for personal and group advice must be presented in a way which makes them easy to understand and within easy reach of pupils. According to the passage one of the problems for pupils entering secondary schools is that______
A. they are taught by many different teachers
B. they do not attend lessons in every subject
C. the teachers do not want to be friendly
D. the teachers give most attention to excellent pupils
