Question

Life in space will certainly take some getting used to！But the space station has been designed to keep the astronauts as comfortable as possible—the modules(艙) are roomy，bright，and kept at a constant 70 degrees Fahrenheit.It’s important the crew members are comfortable because they’ll be busy aboard the station.In a typical workday，crew members will spend 14 hours working and exercising,1.5 hours preparing and eating meals，and 8.5 hours sleeping.Here are some other fun facts about life aboard the station：
Food
Come mealtime，astronauts will have a special dining kitchen.Space food just keeps getting better—and more like food we enjoy here on Earth.In early space missions，astronauts could eat only freeze­dried food that didn’t require any preparation.But the space station is equipped with water，microwave ovens，and refrigerators，allowing the folks on board to eat more “normal” types of food，including fruit，vegetables，and ice cream!
Sleep
Each crew member has a private room.With no gravity，they’ll need to tie themselves to their beds，or they will float away！That might sound like a strange way to sleep，but astronauts from past space missions report that sleeping in space is actually pretty great!
Exercise
You might not think it，but exercise is even more important on the station than it is on Earth.There is not much gravity in space.Astronauts don’t stand up，sit down or walk in space，so their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this，astronauts on the station will exercise on bikes，rowing machines，and other equipment about two hours every day.
Clothing
Astronauts will have to wear special space suits while traveling aboard the U．S.shuttle or Russian rockets.But once they’re safe inside the space station，crew members can wear regular clothing.Of course，a specially designed，pressurized space suit is required for space walks.It has to withstand(經受住) flying pieces and protect the astronauts from dramatic temperature changes.It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.
Personal Cleanliness
Simple tasks like brushing your teeth can be challenging in a weightless environment.A little water doesn’t flow in a stream—it suspends in a bubble！Astronauts will use a freshwater hose(軟管) to take showers，shampoo，and wash off—then a second vacuum hose to suction(吸) off the dirty water.And how do you go to the bathroom in space？With a special “air toilet” that uses flowing air instead of water to dispose of waste.
小題1:The facts about life in space are all mentioned EXCEPT ________.

A．clothing	B．entertainment
C．sleep	D．exercise

小題2:What can be learned from the paragraph “Clothing”？

A．The temperature is quite different in different places in space.

B．Astronauts must wear special space suits all the time in space.

C．Astronauts can wear regular clothing for space walks now.

D．Astronauts wear pressurized space suits just to keep warm.

小題3:Why is exercise more important in space than on earth?

A．It can make astronauts feel relaxed in space.

B．It can help astronauts spend their spare time happily.

C．Astronauts’ lives are more important in space than on earth.

D．It can prevent astronauts from causing muscle and bone loss.

小題4:What do we know about space food from the text?

A．Astronauts could eat apples in space in the past.

B．Astronauts eat only fruit，vegetables and ice cream now.

C．Fresh food isn’t available to astronauts in space.

D．Space food is getting better now than before.

Answer 1

小題1:B
小題2:D
小題3:D
小題4:A

小題1:B
解析　細節理解題。通讀全文可知，第三段是關于sleep；第四段是關于exercise；第五段是關于clothing，文章并未提到宇航員的娛樂活動(entertainment)，故答案為B項。
小題2:D
解析　推理判斷題。第二段第二句指出，太空食物越來越像我們在地球上所吃的食物，接著指出在過去宇航員只能吃凍干的食物，但現在能吃水果蔬菜等平常食物。由此判斷，太空食物比過去好了。
小題3:D
解析　細節理解題。由第四段第三、四句“...their muscles and bones don’t have to work much—and this muscle and bone loss can be dangerous back on Earth.To fight this...”可知，由于太空無重力，人不用坐立行走，運動的機會極少，容易給人的肌肉及骨頭造成危害，因此宇航員必須每天鍛煉兩小時，由此可知正確答案為D項。
小題4:A
解析　細節理解題。根據文章倒數第二段最后一句“It can range from 120 degrees below Fahrenheit in the shadow of the station to 250 degrees in the hot sun.”可知，太空中不同地方溫差是非常大的，故答案為A項。
