7．The elevator of the future may be just over the horizon thanks to German company ThyssenKrupp．The firm has invented a cable-free elevator （called MULTI） that can go up and down like traditional lifts but the magnetic motors allow it to go side-to-side too．The designers predict that this technology could incrase the carrying capacity of existing architecture by as much as 50%．Plus it looks really neat．
ThyssenKrupp plans to use light-weight materials to build its elevator ears of the future and the lack of a cable winch（鋼纜絞車）will reduce weight as well．The ears wouldn't just move up and down as they do now but would instead go in a circle that allows more cars to slip in fight behind the next．The result is that you might only have to wait 10seconds for the next one to arrive rather than wait for the one you just missed to come back down．
The technology backing ThyssenKrupp's MULTI elevator is very similar to magnetic levitation（磁懸�。﹕ystems used in high-speed trains．Each car has two magnetic motors-one for vertical movement and another for horizontal．This system can also deliver power to the car's internal lighting and electronics without using wires．
A traditional cable driven elevator has mechanical components that can hold the car in place in the event of a power-off．ThyssenKrupp didn't go into detail about safety measures in its announcement but it's safe to say the magnetic levitation elevator will have some sort of system to hold it in place if the lights go out．ThyssenKrupp is working on a test tower that will be used to develop the MULTI into a real elevator technology．This should be up and running by 2016but it will probably take at least a few more years before you get to climb inside a magnetic elevator car．
32．What does the underlined phrase"over the horizon"mean？C
A．Above sea level．      
B．On the rise．     
C．On the way．    
D．Out of sight．
33．MULTI is designed toB．
A．save energy      
B．carry more passengers
C．run much faster   
D．be neat and comfortable
34．The key technology about MULTI is itsA．
A．magnetic motor   
B．cabl winch
C．wireless electronics  
D．lighting material
35．What can be learned from the last paragraph？D
A．MULTI will sell well．
B．MULTI has to work on a tower．
C．MULTI will be put into use in 2016．
D．MULTI has a safety system in case of power-off．

The idea of giving someone a puppy for Christmas provides a warm fuzzy response for most people．（36）C  Pets carry a lot of responsibility，but they reward their owners with years of love and devotion．

3．Here a re some of our favorite study tips that will help any student study smarter，not harder：
Recite As You Study
Reciting-saying things out loud should first take place as you read through each paragraph or section．Test yourself．This will help you to understand as well as learn faster because it is more active than reading or listening．It will also help y ou to notice your mistakes and the topics you have trouble understanding．
Take Fuller Notes
Notes should be in your own words，brief and clear．They should be tidy and easy to read．Writing notes will help you better than just underlining as you read，since it forces you to rewrite ideas in your own words．
Study the Middle
The best time to review is soon after you've learned something．You are more likely to remember the material at the beginning and the end of th e lesson，so make sure you focus on the middle when you review．
Sleep on It
Study before going to bed，unless you are very tired．It's easier to remember material you've just learned after sleeping than after an equal period of daytime activity，because your brain continues to think even after you've fallen asleep．
Combine Memory and Understanding
There are two ways to remember：by memorizing and by understanding．Multiplication tables（乘法表），telephone numbers，and math formulas are better learned by memorizing，while ideas are best learned by understanding．
The more ways you have to think about an idea，the more meaning it will have； the more meaningful the learning，the better you can remember it．Pay attention to similarities in ideas and concepts，and then try to understand how they fit in with things you already know．Never be satisfied with anything less than a completely clear understanding of what you are reading．If you are not able to follow the thought，go back to the place where you first got confused and try again．
4．You can notice your mistakes byA．
A．saying things out aloud         
B．taking notes
C．studying the middle             
D．sleeping on it
5．When taking notes，you shouldBto better help you with reading．
A．underline important notes           
B．write notes in your own words
C．take down every detail          
D．write as quickly as possible
6．The writer advises you toDas it is easier for you to remember ma terial．
A．study after a period of activity    
B．do some exercise after studying
C．study as soon as you get up         
D．study before going to sleep
7．Which of the following is NOT helpful for your understanding？C
A．Thinking about an idea in different ways．
B．Relating ideas and concepts with what you already know．
C．Reading from the beginning to the end without stop．
D．Going back to what first made you confused and start again．
