It's a fact that we all dream. Some dreams seem to last for hours, others only for seconds. Some of us have strange dreams, some have interesting dreams, and some of us have unpleasant dreams. Tests in the 1980s showed that these dreams occur within 90-minute cycles, each cycle made up of six stages. In the last stage people experience rapid eye movement, known as REM, and it is in this stage that dreaming takes place. Eighty percent of people who were woken during this sixth stage could easily remember their dreams. On the other hand, when during the first five stages (NREM), only seven percent could describe a dream.

However, of these same people woken during the first five stages, 74% were able to remember thinking activity, although they would not call it a dream. NerysDee, who has written about dreams in a book called "Your Dreams and What They Mean" says: "Perhaps during NREM sleep we are sorting out our outer mundane problems, but in REM sleep we are dealing with inside matters." She also makes the following statement about 90-minute cycle: It may also prove the reason why insomniacs who wake in the middle of the night find it impossible to get to sleep again for at least an hour and a half. In other words, until they have missed out one complete 90-minute sleep period.

1.Which of the following statements about dreams is TRUE?

A. Everyone dreams but very few can recall what they dream.

B.Some people have long dreams and others have very short ones.

C. People can only remember unpleasant dreams.　

D.More than eighty percent of people can remember their dreams.

A.between each 90-minute cycle　　　　　　　 　　

B. at any time during 90-minute cycles

C.during the first five stages of 90-minute cycles　

D. in the last stage of 90-minute cycles

3.People woken during REM sleep can______.

A. hardly remember their dreams　　　　　

B. easily remember their dreams　　

C. only remember their dreams　　　　　　

D. partly remember their thinking activity

4."Insomniacs" are persons who______.

A. can always remember their dreams

For centuries people dreamed of going into space. This dream began to seem possible when high-flying rockets were built in the early 1900s.

In 1903 a Russian teacher named Konstantin Tsiolkovsky figured out how to use rockets for space travel. His plan was the first one in rocket science to use correct scientific calculation. About 30 years later, a U.S. scientist named Robert Goddard built the first rockets that could reach high altitudes. During World War II, German scientists built large rockets that could travel very far and carry dangerous explosives. After the war, scientists from Germany went to the United States and the Soviet Union to help those countries build space rockets.

These two countries were soon racing to get to space first. Each of these countries wanted to prove that it was stronger and more advanced than the other one. Both countries also had powerful bombs. People in the United States were worried when the Soviets were first to launch a space satellite, which was called Sputnik. The Soviets were also first to send a person into space. Yury Gagarin orbited the earth in the Vostok I spaceship in 1961.

The US government set a goal for its space program to be the first country to put a person on the Moon. The U.S. space program built a series of Apollo spaceship. These vehicles were powered by huge Saturn 5 rockets. In 1969 Apollo II took three men to the moon successfully. Nell Armstrong became the first person to walk on the Moon.

The Soviets may have lost the race to fly people to the Moon, but they built the first space station in 1971. The United States also built a space station. The space stations allowed people to live and work in space. Then the Soviet Union and the United States cooperated to hook two spaceships together in space. This action ended the "space race". Today a much larger space station, built by several countries together, orbits Earth.

Another new way to go to space is by space shuttle. A space shuttle, first made in the United States in 1981, looks like an airplane. Astronauts who fly spaceships have used shuttles to help put satellites into space.

It’s a popular belief that a fish’s memory lasts for only seven seconds. It may seem sad to think that they don’t remember what they’ve eaten or where they’ve been, and they don’t identify you or any of their friends -- every moment in their life would be like seeing the world for the first time.

But don’t be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago. In the study, researchers from Mac Ewan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again. Researchers used computer software to monitor the fish’s movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences.

In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively（挑衅地）in front of certain fish, perhaps because they remembered their past “fights”. But until the latest findings, there was no clear evidence.

Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. “If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks,” lead researcher Trevor Hamilton told Live Science.

For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence.

1.According to the article, people commonly believe that _______.

A.fish can only remember part of their past experiences

B.fish can remember things that happened long time ago

C.a fish’s memory lasts for only seven minutes

D.fish don’t recognize any of their friends

2.How can fish benefit most from a good memory? They can remember _______.

A.where to get food and survive

B.their enemies and fight

C.where to escape to when in danger

D.their friends and help each other

3.Which of the following is TRUE according to the passage?

A.African cichlids always treat other fish aggressively.

B.African cichlids can remember things for 12 days.

C.African cichlids don’t belong to the list of smart animals.

D.Only African cichlids have a good memory.

4.What is the article mainly about?

A.Fish having very bad memories.

B.Fish being smarter than we thought.

C.How fish improve their memory.

D.What we can learn from fish.

Making beers on the moon might seem like a pipe dream to many, but for a group of students from the University of California at San Diego, there is a chance to take their research beyond Earth’s surface.

The Lab2Moon competition, held by TeamIndus, is offering students the chance to secure a spot on the TeamIndus rocket this year.

Taking craft beer to the next level, the students want to test whether it’s possible for yeast(酵母) to work and create beer on the moon. However, they believe the experiment is not just a creative concept for astronauts, it’s also important for the development of drugs and yeast-containing food, like bread.

“The idea started out with a few laughs among a group of friends,” said Neeki Ashari, a fifth-year bioengineering students at UC San Diego. “We all appreciate the craft beer. When we heard that there was an opportunity to design an experiment that would go up on India’s moonlander, w e thought we could combine our hobby with the competition by focusing on the practicality of yeast in outer space.”

The preparation work for the beer — up to the stage of adding yeast — will all be done on Earth, and rather than separating the fermentation ( 发酵) and carbonation stage of making beer, the team plans to combine them.

This removes the need to release CO2 accumulated in the process, which may result in cleanliness and safety issues out in space.

If selected, Team Original Gravity will be the first to make beer in outer space, and the fermentation will take place in a container no bigger than a soda can.

All teams competing for the place will showcase their ideas in Bangalore, India, in March.

Sadly, you won’t be enjoying moon beer in your local craft beer bar anytime soon, as no samples will be brought back. However, this small experiment could provide important data on just how practical it is for us to make and create our own resources on other planets and moons by learning how consumables (消耗品) behave in different environments.

1.How did the students feel when they got the chance to design the experiment ?

A.Excited. B.Nervous.

C.Confident. D.Casual.

2.What does the underlined word “This” in Paragraph 6 refer to?

A.The mixing of two stages. B.Adding yeast on Earth.

C.The preparation work on Earth. D.Fermentation and carbonation.

3.What can we learn about the experiment from the passage?

A.It has been designed based on similar experiments.

B.It’s quite competitive compared with other designs.

C.It’s design has already been approved by TeamIndus.

D.Its process was adapted to make it safer and greener.

4.What does the author think of the students ’ idea?

A.It seems like a pipe dream. B.It’s extremely complicated.

C.It’s meaningful and hopeful. D.It’s creative but impractical.

Why do we dream? It’s a question researchers have been studying for years. Now new research suggests that some dreams may result from the brain’s effort to keep learning, even as we sleep.

In a study in Boston, 100 volunteers were trained for an hour on a maze (迷宫). They tried to find their way through the difficult puzzle as quickly as possible. Then half of the volunteers were allowed to sleep for 90 minutes. The other half stayed awake, reading or relaxing. The ones who slept were asked to describe their dreams when they woke up.

After the rest, the volunteers were asked again to solve the maze. Those who hadn’t slept showed no improvement or did even worse after the break. Sleepers who didn’t report any maze-related dreams did better but showed only a little improvement. However, 4 nap-takers who reported dreaming about maze showed a surprising improvement. They scored 10 times higher after sleeping and dreaming about the maze.

Even though the number of dreamers was small, the researchers noted that the gap in learning between the dreamers and the non-dreamers was so wide that the finding was significant.

The dreamers had all performed poorly on the test before dreaming about it. That suggests that struggling with a task might be the trigger that leads the sleeping brain to focus on it and work on how to deal with it.

“It’s almost as if your brain is going through everything that happened today,” Dr. Stickgold, a scientist at Harvard Medical School, said, “The things you are obsessed (着迷的) with are the ones that your brain forces you to continue to do with. ”

1.What’s the best title of the passage?

A.Learning while you dream. B.What dreams stand for.

C.Dream a good dream. D.Dreams and health.

2.What were the volunteers asked to do after the rest?

A.To work on a new maze.

B.To continue to do the maze.

C.To talk with each other about their dreams.

D.To tell what they thought about the maze.

3.According to the study, which group showed the greatest improvement?

A.Those who didn’t sleep.

B.Those who slept but didn’t dream.

C.Those who dreamed about the maze while sleeping.

D.Those who thought about the maze before falling asleep.

4.The underlined word “trigger” in paragraph 5 probably means ________.

5.In which part of a newspaper would you most probably read this passage?
