题目列表(包括答案和解析)
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(舱) 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 freeze?dried 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(经受住) 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(软管) 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.
1.The facts about life in space are all mentioned EXCEPT ________.
A.clothing? B.entertainment
C.sleep? D.exercise
2.What can be learned from the paragraph “Clothing”?

C.Astronauts can wear regular clothing for space walks now.
D.Astronauts wear pressurized space suits just to keep warm.
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.
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.
The baby is just one day old and has not yet left hospital. She is quiet but alert (警觉). Twenty centimeters from her face researchers have placed a white card with two black spots on it. She stares at it carefully. A researcher removes the card and replaces it by another, this time with the spots differently spaced. As the cards change from one to the other, her gaze(凝视) starts to lose its focus - until a third, with three black spots, is presented. Her gaze returns; she looks at it for twice as long as she did at the previous card. Can she tell that the number two is different from three, just 24 hours after coming into the world?
Or do newborns simply prefer more to fewer? The same experiment, but with three spots shown before two, shows the same return of interest when the number of spots changes. Perhaps it is just the newness? When slightly older babies were shown cards with pictures of objects(a comb, a key, an orange and so on), changing the number of objects had an effect separate from changing the objects themselves. Could it be the pattern that two things make, as opposed to three? No again. Babies paid more attention to squares moving randomly on a screen when their number changed from two to three, or three to two. The effect even crosses between senses. Babies who were repeatedly shown two spots became more excited when they then heard three drumbeats than when they heard just two; likewise(同样地) when the researchers started with drumbeats and moved to spots.
1.The experiment described in Paragraph 1 is related to the baby’s ______.
A.sense of hearing.
B.sense of sight.
C.sense of touch.
D.sense of smell.
2.Babies are sensitive to the change in ______.
A.the size of cards.
B.the colour of pictures.
C.the shape of patterns.
D.the number of objects.
3.Why did the researchers test the babies with drumbeats?
A.To reduce the difficulty of the experiment.
B.To see how babies recognize sounds.
C.To carry their experiment further.
D.To keep the babies’ interest.
4.Where does this text probably come from?
A.Science fiction.
B.Children’s literature.
C.An advertisement.
D.A science report.
Hanukkah
Hanukkah (光明节) is a Jewish festival. It is celebrated on the 25th day of the Jewish month of Kislev (犹太教历), which is usually sometime in December. It is often called the festival of lights. The festival celebrates the time, over 2,000 years ago, when the Jewish people fought against an emperor who would not let them follow their own traditions and religion. When the Jewish people won back their temple in Jerusalem, they found there was only enough holy oil to keep the sacred light burning for one day. However, to their surprise, this small amount of oil kept the light burning for eight days and nights, until the people had time to make more oil.
At the center of the Hanukkah celebrations is a candlestick (called a Menorah) that holds nine candles. On the first night of Hanukkah the first candle is lit, and each day this candle is used to light another candle, until on the eighth day, the last day, all the candles are lit. During Hanukkah, people go to the synagogue (犹太教堂) to pray and to remember the miracle (奇迹) of the holy oil. Hanukkah is a time for family and friends to come together. People exchange gifts and greeting cards, and children go to parties. Parents often give their children money at Hanukkah. Potato cakes, called latkes, are a traditional Hanukkah food.

Allow them to study in blocks of time, such as for half an hour with a five-minute break in the middle. 2. . Ideal (理想的)study times are after dinner or right after school before dinner.
Never allow your children to study in front of the television, as that will encourage passive activity. 3.
You’ll also need to help your kids find the right place to study. After you’ve set up a good study time for little learners, set up a good place where they can get those creative juices flowing.
4. Make sure there is a table or a desk and a comfortable chair.
5. This includes helping them out with their homework sometimes and being there for them with the answers to any questions. The input you give your children during study periods will help form a bond and help make studying enjoyable.
