Tests administered（實(shí)施）to most elementary and high-school students in the United States exert（發(fā)揮）an unfavorable influence on science and math teaching， according to a new ＄1 million study performed for the National Science Foundation．And because schools with high minority enrollments（入學(xué)）generally place a greater reliance（相信）on scores from these tests， the study finds，there tends to be “a gap in instructional emphases between high and low minority classrooms that differs from our national concern for the quality of education．”

George F．Madaus and his colleagues at Boston College analyzed not only the six most widely used national standardized tests， but also the tests designed to accompany（go with）the four most commonly used science and math texts in fourth-grade，eighth-grade，and high-school classrooms．Though curriculum（teaching program）experts argue that schools should place greater emphasis on problem solving and reasoning， the new study shows that the tests focus on lower-level skills—primarily mechanical memorization of routine formulas（公式）．

Researchers surveyed more than 2，200 math and science instructors，interviewing in depth some 300 teachers and administrators．Especially in schools with high minority enrollments，teachers reported feeling pressured to help students perform well on these tests．Some states judge schools and some schools determine teacher assignments（工作安排）based on students' test scores．

“With so much worry，”Madaus says，“teachers feel forced to focus their instruction on drilling what the tests will measure—at the expense of the more valuable，higher-level skills．”

The author of this article states that ____  _ ．

A．the tests don't affect teaching in most elementary and high schools

B．the science and math teaching is influenced by the present tests

C．no study is performed on tests for the National Science Foundation

A．the students can not get high score from the tests

B．scores from the tests are not important

According to the second paragraph，the study has discovered that ____  _ ．

A．emphasis of teaching is on problem solving and reasoning

B．curriculum is good for national standardized tests

C．the tests mainly center around the memorization of some formulas

D．routine formulas are not useful for students to memorize

According to Madaus' opinion，teachers are forced to ____  _ ．

A．evaluate（評(píng)估）students' skills every year

B．suffer so much worry on the texts

C．teach what will be tested

D．focus their instruction on useful drillings

Fat and shy，Ben Saunders was the last kid in his class picked for any sports team. “Football，tennis，cricket—anything with a round ball，I was useless，” he says now with a laugh. But back then he was the one always made fun of in school gym classes in Devonshire，England.

It was a mountain bike he received for his 15th birthday that changed him. At first he went biking alone in a nearby forest. Then he began to ride the bike along with a runner friend. Gradually，Saunders set up his mind on building up his body，increasing his speed and strength. At the age of 18，he ran his first marathon.

 The following year he met John Ridgway and was hired as an instructor at Ridgway’s school of adventure in Scotland，where he learnt about Ridgway’s cold-water exploits. Greatly interested，Saunders read all he could about North Pole explorers and adventures，then decided that this would be his future.

　　In 2001，after becoming a skillful skier，Saunders started his first long-distance expedition towards the North Pole. It took unbelievable energy. He suffered frostbite，ran into a polar bear and pushed his body to the limit，pulling his supply-loaded sled up and over rocky rice.

　　Saunders has since become the youngest person to ski alone to the North Pole，and he’s skied more of the North Pole by himself than any other British man. His old playmates would not believe the change.

Next October，Saunders，27，heads south from the coast of Antarctica to the South Pole and back，a 2900-kilometer journey that has never been completed on skis.

Which of the following is the correct order of the events that happened to Saunders?

    a. He ran his first marathon.

 b. He skied alone in the North Pole.

　  c. He rode his bike in a forest

.d. He planned an adventure to the South Pole.

　A. a-c-d-b  B. c-d-a-b  C. a-c-b-d  D. c-a-b-d

The underlined word “exploits” is closest in meaning to______

  A. journeys   B. operations   C.  researches    D. adventures

The story mainly tell us about Saunders that he is______

A. a good instructor at school   B .the best British skier

C. Ridgway’s favorite student   D. a success in sports

Ben Saunders______after he was 15 years old .

  A. become good at most sports.    B. began to build up his body.
