We've all heard the saying: practice makes prefect! In other words, acquiring skills takes time and effort. But how exactly does one go about learning a complex subject such as tennis, calculus, or even how to play the violin? An age-old answer is: practice one skill at a time. A beginning pianist might rehearse scales(音阶) before chords(和弦). A young tennis player practices the forehand before the backhand. Learning researchers call this “blocking”， and because it is common and easy to schedule, blocking is dominant in schools, training programs, and other settings.
However another strategy promises improved results. Enter “interleaving”， a largely unheard-of technique that is catching the attention of cognitive(认知) psychologists and neuroscientists. Blocking involves practicing one skill at a time before the next (for example, “skill A” before “skill B” and so on, forming the pattern “AAABBBCCC”), while in interleaving one mixes practice on several related skills together (forming for example the pattern “ABCABCABC”).
Over the past four decades, a small but growing body of research has found that interleaving often outperforms blocking for a variety of subjects, including sports and category learning. Yet there have been almost no studies of the technique in unplanned, real world settings-until recently. New research in schools finds that interleaving produces dramatic and long-lasting benefits for an essential skill: math. Not only does this finding have the potential to transform how math is taught, it may also change how people learn more generally.
Researches are now working to understand why interleaving produces such impressive results. One important explanation is that it improves the brain's ability to tell apart between concepts. With blocking, once you know what solution to use, or movement to do, the hard part is over. With interleaving, each practice attempt is different from the last, so rote(死记硬背) responses don't work. Instead, your brain must continuously focus on searching for different solutions. That process can improve your ability to learn critical features of skills and concepts, which then better enables you to select and produce the correct response.
A second explanation is that interleaving strengthens memory associations. With blocking, a single strategy，temporarily held in short-term memory, is sufficient. That's not the case with interleaving-the correct solution changes from one practice attempt to the next. As a result, your brain is continually engaged at regaining different responses and bringing them into short-term memory. Repeating that process can strengthen neural connections between different tasks and correct responses, which improves learning.
Both of these accounts imply that increased effort during training, either to discriminate correct responses or to strengthen them, is needed when interleaving is used. This corresponds to a potential drawback of the technique, namely that the learning process often feels more gradual and difficult in the beginning. However, that added effort can have better, longer-lasting results.
1.What can we learn from the new strategy of “interleaving”？
A. Studying related skills together has many impressive results.
B. Learning relevant skills together contributes to people mastering skills quickly.
C. Focusing on different skills at a time saves people time and efforts in the beginning.
D. Mixing up skills distracts people's attention, thus lessening efficiency.
2.Why does interleaving produce impressive results?
A. It can be scheduled easily.
B. It focuses on rote responses.
C. It is temporarily held in short-term memory.
D. It enables you to learn critical features of skills and concepts.
3.What does the passage mainly talk about?

B. Correct solution often changes from one practice attempt to the next.
C. Practising one skill at a time plays an important role in learning a complex subject.

Sure, we've all heard that we should get more sleep. The realities of life often make it become "we should get more sleep later." 1. The result is that you wake up the next day feeling like a role of The Walking Dead. Here are four ways you can adjust your biology in order to pay less for staying up.
● Move around.
Exercising before bed is a sure way to keep awake. That's why you shouldn't do it when you want to go to sleep, and it is also why hitting the gym, or even some fast push-ups can tell your body that it's not time for bed. Being physically exhausted isn't fun when you are trying to stay up late. 2.
● Eat more protein.
Few people think about the fact that the brain and body use a lot more energy when we're awake. If you are pulling an all-nighter, you're going to need a lot more food than you are used to eating. 3. To stay awake, plan to eat larger meals than normal and to eat them more frequently.
● Drink the right stuff.
It's tempting (诱人) to switch to sugary caffeine drinks like Red Bull, but the sugar will lead to a crash. Instead, if you want to use caffeine, drink early in the evening so it'll wear off by the time you want to sleep.
4. Don't make it worse by drinking sugar.
● 5.
Turn the lights down at night because bright lights keep you awake. For three or four hours after you're exposed to bright white light, your body won't make melatonin, a must for deep sleep. You will sleep better if you turn the lights a little bit down.
A. Turn the lights off.
B. Avoid bright lights.
C. Just do enough to get energetic.
D. And your body can never bear something like that.
E. Your brain can use up to 25 percent of your total calories.
F. When you stay up late, your blood sugar becomes abnormal.
G. There is either more work to be done, or more fun to be had, or both.

The other day I heard a few local musicians talking:
“I hate all the terrible pianos in this town. I hate that rubbish they play on the radio. They can’t even understand a bit of music.”
“I’m never playing in that club again. Too many drunks and nobody listens to us.”
But, one younger musician said, “There are a few clubs that book my band a few nights a month, and I’m trying to find other places to play. I’m also looking to book a few summer festivals this year.”
I’ve heard that you are the average of the five people whom you spend the most time with, or to put it another way, you are who your friends are.
Attitudes are important. Whether they’re positive or negative, they’re rubbing off on you. If you’re around people who complain about lack of work and about other musicians, or blame (责怪) others, and you play the role of victim (受害者), chances are you will start to as well. So it’s time to take a look at the people you call “friends”.
This is an easy exercise: Make a list of the people who you hang out with, and simply stop spending time with the negative people on your list. Set a new standard (标准) for yourself and don’t become friends with people who fall below that standard.
Keep successful people around you and your own chances for success will be much better. Ask them how they do it. Ask if they will help you get the work you’re looking for, or maybe give you some advice to help you on your career path.

A．the musicians’ living conditions are quite poor
B．people have poor taste in music
C．people have different attitudes towards the same thing
D．young people have greater chances of succeeding

Should we try to contact and make friends with other beings in the universe? Certainly not，says British physicist Stephen Hawking．
“If aliens（creatures from other planets）ever visit us, I think the outcome would be much as when Christopher Columbus first landed in America, which didn’t turn out very well for the Native Americans,’’ said the 68-year-old disabled scientist in a new Discovery documentary (纪实性电视节目) on April 25．
The program pictures an imagined universe where other life forms in huge spaceships hunt for resources after using up all those on their home planets．
“Such advanced aliens would perhaps become nomads(游牧民)，looking to conquer and colonize whatever planets they can reach，”warned Hawking．
On the probability of other life forms existing, he says, “To my mathematical brain, the numbers alone make thinking about aliens perfectly reasonable.”
Hawking’s concerns have frightened some people and been met with disagreement from other researchers．Paul Davies, author of the book Renewing Our Search for Alien Intelligence，thinks Hawking’s reasoning is wrong.
He argues that since Earth is about 4.5 billion years old，if intel1igent life is likely , communities of other beings may have been there for a very long time．
“If resources are the factor, then at least one group of aliens would surely have visited Earth as a destination mil1ions of years ago．
Even if other life forms do come to Earth in the near future, Davies believes comparisons with are wide of the mark(离谱的).
68. What is the article mainly about?
A. Other life forms coming to our planet．
B. Scientific evidence of other life forms．
C. Earth as the only place where human beings can survive．
D. Hawking’s belief that other life forms may exist in the universe．
69. Which of the following ideas is opposed to Hawking’s view?
A. Other life forms exist in the universe．
B. 0ther life forms may be more intelligent than human beings．
C. We should try to contact other 1ife forms from other planets．
D. Other life forms may exist in more than one part of the universe．
70. Paul Davies didn’t agree with Stephen Hawking ,believing that ________．
A. the universe is running out of resources
B. humans are the best creatures in the universe.
C. it is a good idea to avoid meeting with other life forms
D. Davies doesn’t think it proper to compare aliens with Columbus
71. Hawking referred to Christopher Columbus as an example to ____．
A. inspire interest in the universe
B. draw attention to other planets in the universe
C. warn people to watch out for other life forms
D. urge further exploration of the universe~

We’ve all heard about the power of our attitude, and it’s our attitude that determines how much we succeed in life.
All the things that you have been through, all the people you have met and interacted with can have an impact on your attitude. If you think that all these factors have molded you into a person with a poor attitude towards life, there is no need to worry. 1.
Identify and understand what you want to change.
The first step towards change is clearly understanding what needs to be changed. 2. When it comes to changing your attitude, you need to do an honest and in-depth self-evaluation so you could point out exactly which of your traits need to be improved or totally changed.
3.
Find someone who has the kind of attitude that you want to have, and let his or her life give you inspiration and encouragement to move beyond your temporary failures in your journey towards becoming a better person.
Choose the right company.
As they say, “Bad company corrupts good character.” You don't expect yourself to be able to change if you go on surrounding yourself with people who possess all the negative traits that you want to change. Consider befriending new people, especially those who are optimistic and have a healthy attitude towards life. 4.
Believe that you are able to change.
5.If you don’t believe in yourself or believe that you or your life can change, it just won't happen—you will either never start, or give up quickly that you won't have even given yourself the opportunity to succeed.
A. Look for a role model.
B. There is always an opportunity for change.
C. Setting clear goals is the key to success in any endeavor.
D. Think about how your attitude change will affect your life.
E. The greatest obstacle is our inability to trust in what we can do.
F. Your effort to change will be easier with these people as friends.
G. Fix your mind on the things that would come as a result of your attitude change.

Have you ever heard the saying “All roads lead to Rome”? At one time, this was pretty much true. During the Roman Empire, lots of roads were built in order to move armies, send messages by courier (信使), and make trade easier.
The network of Roman roads was begun in 312 BC. It was demanded that the roads be built strong so that they would not fall down. Roman soldiers, supervised (监督) by engineers, laid down the roads in a special pattern of layers. There were all together 4 layers, which was made of different materials, such as sand, rocks, stones and so on.
Also, Roman roads were cambered(拱形). This means that they were built higher in the middle than on the edges, allowing rainwater to run off, which prevented flooding. We use the same technique in building roads today. The Romans also laid out roads over hills when necessary, setting them down in a zigzag (之字形的)pattern to make the road rise gradually.
All Roman roads had milestones (里程碑), placed every thousand paces (a Roman mile). The milestones told when the road was built, who was emperor at the time, the road’s destination, how far the traveler was from the destination, and how many miles had been traveled since the beginning of the road. This information was a great help to travelers.
Because of their excellence in construction, it really is no surprise that many parts of Roman road still exist today. These roadways are one of the most impressive achievements of the Roman Empire.
1.The following description about Roman roads is true EXCEPT _____.
A. Roman roads were built by the Roman soldiers directed by the engineers
B. Roman roads could prevent flooding using the technique we don’t use today
C. Roman roads had milestones that were placed every Roman mile
D .Roman roads still exist today as an impressive achievement of Roman Empire
2.What information can you find on the milestones?
A. The builders of the road.
B. The materials used in building roads.
C. The distance from one city.
D. The time spent in building roads.
3.The passage mainly ______.
A. explains the saying “All roads lead to Rome”
B. praises ancient Romans for their great achievements
C. shows how great the Roman Empire was
D. introduces the construction of the Roman roads
