Part III Reading Comprehension (40 minutes)2016年6月大学英语四级卷1真题及答案

Section A

Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.

Questions 26 to 35 are based on the passage you have just heard.

Physical activity does the body good, and there's growing evidence that it helps the brain too. Researchers in the Netherlands report that children who get more exercise, whether at school or on their own, 26 to have higher GPAs and better scores on standardized tests. In a 27 of 14 studies that looked at physical activity and academic 28 , investigators found that the more children moved, the better their grades were in school, 29 in the basic subjects of math, English and reading.

The data will certainly fuel the ongoing debate over whether physical education classes should be cut as schools struggle to 30 on smaller budgets. The arguments against physical education have included concerns that gym time may be taking away from study time. With standardized test scores in the U.S. 31 in recent years, some administrators believe students need to spend more time in the classroom instead of on the playground. But as these findings show, exercise and academics may not be 32 exclusive. Physical activity can improve blood 33 to the brain, fueling memory, attention and creativity, which are 34 to learning. And exercise releases hormones that can improve 35 and relieve stress, which can also help learning. So while it may seem as if kids are just exercising their bodies when they're running around, they may actually be exercising their brains as well.

Passage 6
The U.S. dollar was supposed to be at the end of its rope. Kicking the bucket. A dying symbol of a dying empire. Well, maybe not. The dollar continues to _1_ gloom-and-doom predictions. After a swoon (低迷）last year, the dollar is again enjoying a major _2_. The U.S. dollar index, which measures the dollar’s value against other major currencies, is just off an eight-month high. The main reason behind the dollar’s recovery is actually no real surprise at all. There is no _3_ able to replace the dollar as the world’s No.l currency. What makes currencies so fascinating is that their perceived value is always relative to other currencies. Sure, the U.S. budget deficit is _4_, the government’s debt is increasing, and Wall Street is still repairing itself. But the dollar remains the prettiest of a flock of ugly ducklings. Is any other major industrialized economy _5_ better off than the U.S.？ Not really. Just about the _6_ developed world is suffering with the same problems. That’s why when investors get nervous, they still rush to the good old dollar. The dollar wins because no one else is really in the game. The euro has been exposed as a _7_. Only a few months ago, economists truly believed the euro could _8_ the dollar as the top reserve currency. Now experts are questioning if the euro has a future at all. The Greek debt crisis has _9_ that the euro is only as strong as its weakest link. Maybe over the next 20 or 30 years，the dollar will slowly lose the _10_ status it holds today. That process, however, could well be driven by the appearance of new rivals.
A)fraud
B)consistently
C)dominant
D)expanding
E)entire
F)incentive
G)rival
H)alleged
I)defy
J)particularly
K)alternative
L)relative
