【題目】根據(jù)短文理解，選擇正確答案。
Astronauts on shorter shuttle missions (使命) often work very long days. Tasks are scheduled so tightly that break times are often used to finish the tightly that break times are often used to finish the day's work. This type of scheduled is far too demanding for long missions on the International Space Station (ISS). ISS crewmembers usually live in space for at least a quarter of a year. They work five days on and two days off to mimic the normal way they do things on Earth as much as possible. Weekends give the crew valuable time to rest and do a few hours of housework. They can communicate with family and friends by email, internet phone and through private video conferences.
While astronauts cannot go to a baseball game or a movie in orbit, there are many familiar activities that they can still enjoy. Before a mission, the family and friends of each ISS crewmember put together a collection of family photos, messages, videos and reading material for the astronauts to look at when they will be floating 370 kilometers above the Earth.
During their mission, the crew also receives care packages with CDs, books, magazines, photos and letters. And as from early 2010, the internet became available on the ISS, giving astronauts the chance to do some “web surfing(沖浪)”in their personal time. Besides relaxing with these more common entertainments, astronauts can simply enjoy the experience of living in space.
Many astronauts say that one of the most relaxing things to do in space is to look out the window and stare at the universe and the Earth. Both the shuttle and the ISS circle the planet several times each day, and every moment offers a new view of the Earth's vast land mass and oceans.
（1）What does the word “mimic” in Paragraph 1 probably mean?
A.Find.
B.Copy.
C.Change.
D.Lose.
（2）Which of the following best describes the families of the astronauts on the ISS?
A.They are caring and thoughtful.

【題目】根據(jù)短文理解，選擇正確答案。
Traditionally, across the world, boys and girls attend a mixed school, where they study together. But boys' schools are the perfect place to teach young men to express their emotions (情感) and encourage them to take part in activities such as art, dance and music.
Boys at single-sex schools were said to be more likely to take part in cultural and artistic activities that helped develop their emotional expressiveness, rather than feeling they had to correspond to(和…相符) the "boy code" of hiding their emotions to be a "real man".
The findings of the study go against accepted wisdom that boys do better when taught together with girls.
Tony Little, head master of Eton, warned that boys were being failed by the British education system because it had become too focused on girls. He criticized teachers for failing to recognize that boys are actually more emotional than girls.
The research argued that boys often perform badly in mixed schools because they become discouraged when girls do better earlier in speaking and reading skills.
But in single-sex schools teachers can tailor (量身定做) lessons to boys' learning style, letting them move around the classroom and getting them to compete in teams to prevent boredom, wrote the study's author, Abigail James, of the University of Virginia.
Teachers could encourage boys to enjoy reading and writing with "boy-focused" approaches such as themes and characters that appeal to them. Because boys generally have more acute vision, learn best through touch, and are physically more active, they need to be given "hands-on" lessons where they are allowed to walk around. "Boys in mixed schools view classical music as feminine（女性的） and prefer the modern genre （類型） in which violence and sexism are major themes," James wrote.
Single-sex education also made it less likely that boys would feel that they had to be "masterful and in charge" in relationships. "In mixed schools, boys feel forced to act like men before they understand themselves well enough to know what that means," the study reported.
（1）The author believes that a single-sex school would __________.
A.force boys to hide their emotions to be "real men"
B.help boys to be more competitive in schools.
C.encourage boys to express their emotions more freely
D.naturally strengthen boys' traditional image of a man
（2）It is commonly believed that in a mixed school boys __________.
A.behave more responsibly.
B.grow up more healthily.
C.perform relatively better.
D.receive a better education.
（3）According to Abigail James, one of the advantages of single-sex schools is __________.
A.teaching can be tailored to suit the characteristics of boys
B.boys can focus on their lessons without being distracted
C.boys can choose to learn whatever they are interested in
D.teaching can be designed to promote boys' team spirit
（4）What does the underlined word “acute” in paragraph 8 mean?
A.lovely
B.sharp
C.serious
D.dull
