2．As long as you have broadband（宽带） service in your home，you can turn on your desktop computer and connect to the Internet．If you have a wireless router，a device that spreads the broadband connection to other devices，you can set up a Wi-Fi network，which enables your cellphones and tablets go online too．And when you are outdoors where there is no Wi-Fi，such as in the park or at the beach，having 3G service allows you to stay connected．
  It seems that lots of us have Internet coverage everywhere we go．So why have mobile companies around the world lately been so enthusiastic about a new term，"4G"？First，you need to know that the letter："G"stands for"generation"．Even if you have no idea what 4G is，at least you can figure out that it is a step up from 3G since it's the latest generation of mobile Internet service．
  Unlike broadband，mobile Internet uses the same signal towers that provide voice service to your cellphone，which means wherever you can make phone calls with your cellphone you also have an Internet connection．
  But mobile connections have their defects：they don't carry as much information as broadband does，making opening websites and downloading music slower than they are on a Wi-Fi connection．This is why mobile connections have been constantly upgraded since the first generation was launched back in the 1980s．
  According to BBC，4G is five to seven times faster than current 3G network speeds，almost as fast as home broadband．Because of this，4G is widely suited for services like video downloading，mapping，online shopping and even video conferencing．
  To achieve the high speeds，network companies have to spend a lot of money on building new signal towers，which will eventually lead to a higher phone bill if you switch to 4G，and you will also have to get a new phone with 4G capacity．

1．Tips for Cooking on a Tight Schedule
    From my experience，there are three main reasons why people don't cook more often：ability，money and time．（16）B． Money is a topic I'll save for another day．So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen．Here are three tips for great cooking on a tight schedule：
1．Think ahead．The moments when I think cooking is a pain are when I'm already hungry and there's nothing ready to eat．So think ahead of the coming week．When will you have time to cook？Do you have the right materials already？（17）G．
2．Make your time worth it．When you do find time to cook a meal，make the most of it and save yourself time later on．Are you making one loaf of bread？（18）C．  It takes around the same amount of time to make more of something．So sav e yourself the effort for a future meal．
3．（19）A． This may surprise you，but one of the best tools for making cooking worth your time is experimentation．It gives you the chance to hit upon new ideas and recipes that can work well with your appetite and schedule．The more you learn and the more you try，the more ability you have to take control of your food and your schedule．
Hopefully that gives a good start．（20）F． And don't let a busy schedule discourage you from making some great changes in the way you eat and live!

A．Try new things．
B．Ability is easily improved．
C．Make three or four instead．
D．Understand your food better．
E．Cooking is a burden for many people．
F．Let cooking and living simply be a joy rather than a burden．
G．A little time planning ahead can save a lot of work later on．
20．Life is just like a box．Inside it are happiness and sorrow，failure and success，hope and despair．Life is a learning process．Experiences in it teach us new lessons and make us a better person．
Love
Love plays a key role in our life．Love makes you feel wanted．Without love a person could become cruel and violent．In the early stage of our life，our parents are the ones who show us with unconditional love and care．They tell us what is right or wrong，good or bad．（36）C．It is only after marriage and having kids that a person understands and becomes sensitive to the feelings of others．Kids make a person responsible and mature and help us to understand life better．
Happiness and Sorrow
Materialistic happiness is shortlived，but happiness achieved by bringing a smile on others gives a certain level of fulfillment．（37）G．No mind is happy without peace．We realize the true worth of happiness when we are in sorrow．Sorrow is basically due to death of a loved one，failure and despair．But these things are temporary and pass away．
Failure and Success
（38）F．It helps us to touch the sky，teaches us to survive and shows us a specific way．
Hope and Despair
Hope is what keeps life going．Parents always hope their children will do well．Hope makes us dream．Hope builds in patience．（39）A，because after every night there is a day．Nothing remains the same．We have only one choice-keep moving on in life and be hopeful．
Life teaches us not to regret over yesterday，for it has passed and is beyond our control．Tomorrow is unknown，for it could either be right or dull．（40）B，so that we will enjoy a better tomorrow．

A．Life teaches us not to despair even in the darkest hour
B．So the only alternative is work hard today
C．But we always tend to take this for granted
D．Success lies in trusting yourself
E．So let's enjoy every day
F．Failure is the path to success
G．Peace of mind is the main link to happiness．
19．We are all called upon to make a speech at some point in life，but most of us don't do a very good job．（36）C．
So，you have to give a speech and you are terrified．You get nervous，you forget what you want to say，you stumble（结巴） over words，you talk too long，and you bore your  audience．Later you think，"Thank Goodness，it's over．I'm just not good at public speaking．I hope I never have to do that again．"
Cheep up!（37）A．Here are some simple steps to take the pain out of speech making．
Ask yourself the purpose of your speech．What is the occasion？Why are you speaking？Then，gather as many facts as you can on your subject．Spend plenty of your time doing your research．Then spend plenty of your time organizing your material so that your speech is clear     and easy to follow．Use as many examples as possible，and use pictures，charts，and graphs  if they he lp you make your points more clearly．（38）F．Don't talk down to them．Treat your audience with respect．They will appreciate your thoughtfulness．
Just remember：Be prepared．Know your subject，your audience，and the occasion．Be brief．（39）D．And be yourself．Let your personality come through so that you make person-to-person contact with your audience．
If you follow these simple steps，you will see that you don't have to be afraid of public speaking．In fact，you may find the experience so enjoyable that you volunteer to make more speeches!You're not convinced yet？（40）G．

A．It doesn't have to be that bad．
B．Take several deep breaths before your speech．
C．This article gives some advice on how to give a good speech．
D．Say what you have to say and then stop．
E．Don't give a try to say what you aren't familiar with．
F．Never forget your audience．
G．Give it a try and see what happens．
18．Taking good notes is a time-saving skill that will help you to become a better student in several ways．（36）GSecond，your notes are excellent materials to refer to when you are studying for a test．Third，note-taking offers variety to your study time and helps you to hold your interest．
You will want to take notes during classroom discussions and while reading a textbook or doing research for a report．（37）EWhenever or however you take notes，keep in mind that note-taking is a selective process．（38）F
The following methods may work best for you．
•Read the text quickly to find the main facts and ideas in it．
•Carefully read the text and watch for words that can show main points and supporting facts．
•Write your notes in your own words．
•（39）A
•Note any questions or ideas you may have about what was said or written．
As you take notes，you may want to use your own shorthand（速记）．When you do，be sure that you understand your symbols and that you use them all the time．（40）D

A．Use words，not complete sentences．
B．There are three practical note-taking methods．
C．You must write your notes on separate paper．
D．Otherwise，you may not be able to read your notes later．
E．You will also want to develop your own method for taking notes．
F．That means you must first decide what is important enough to include in your notes．
G．First，the simple act of writing something down makes it easier for you to understand and remember it．
17．What do the world's most successful people all have in common？
By examining the work habits of over 150greatest writers and artists and scientists，the researchers including Stanford professor Jeffrey Pfeiffer found that high achievers like Robert Moses turned out to be all alike：
Busy!Busy!
（31）D In a study of general managers in industry，John Kotter reports that many of them work 60to 65hours per week-which translates into at least six 10-hour days．The ability and willingness to work difficult and tiring hours has characterized many powerful figures．Energy and strength provide many advantages to those seeking to build power．
Just Say No!
The difference between successful people and very successful people is that very successful people say"no"to almost everything．And that's what gives them the time to accomplish so much．（32）B And focus means saying"no"to a lot of distractions （分神）．
（33）F
Ignore your weaknesses and keep improving your strengths．Don't waste time exploring skill areas where you have little competence．Instead，focus on-and build on-your strengths．This means knowing who you are，what you are and what you are good at．
Create Good Luck！
（34）G There's a science to it．Richard Wiseman studies lucky people for his book Luck Factor，and breaks down what they do right．Certain personality types are luckier because they behave in a way that offers the chance for good opportunities．By being more outgoing，open to new ideas，following the feeling that something is true，and being optimistic，lucky people create possibilities．
Does applying these principles to your life actually work？Wiseman created a"luck school"to test the ideas-and it was a success．In total，80percent of the people who attended Luck School said that their luck had increased．（35）C

A．Spend enough time to improve your weakness．
B．Achievement requires focus．
C．On average，these people reported that their luck had increased by more than 40percent．
D．They never stop working and they never lose a minute．
E．Busy people are more likely to be lucky．
F．Know What You Are!
G．Luck isn't magical．

15．It's reported that the Great Fire attacked London in the 17th century．The fire started in the very early hours of the day．In four days it destroyed more than three-quarters of the old city，where most of the houses were wooden and close together．（36）G
On Sunday morning the fire started in the house of the King's baker in Pudding Lane．The baker，with his wife and family，was able to get out through a window in the roof．（37）F Then it spread quickly into Thames Street．That was the beginning．
By eight o'clock three hundred houses were on fire．On Monday nearly a kilometer of the city was burning along the River Thames．（38）A The fire destroyed many well-known buildings，old St Paul's and the Guildhall among them．
People threw their things into the river．Many poor people stayed in their houses until the last moment．（39）E The fire stopped only when the King finally ordered people to destroy hundreds of buildings in the path of the fire．With nothing left to burn，the fire became weak and finally died out．
After the fire，the city was expected to be rebuilt with wider streets and fine new houses of stone．（40）BBut more than fifty churches were also rebuilt，among them new St Paul's．
Although great pain and loss was caused by the fire，after it London was rebuilt as a better place：a city for the future and not just of the past．

A．Tuesday was the worst day，for more buildings were caught in the fire．
B．In fact，the streets were still narrow after totally rebuilt．
C．At last，the streets became much wider．
D．The family were able to survive the fire after all．
E．The homeless had to wander in the streets for no shelter to stay．
F．A strong wind blew the fire from the bakery into a small hotel next door．
G．One hundred thousand people became homeless，but only a few lost their lives．
14．Identity theft （身份盗用） is one of the fastest-growing crimes．Identity theft is a crime in which your personal information is stolen by someone and is used in an illegal way．When your identity is stolen，the thief often does fraud （诈骗） with that．（36）BAnd you have to be responsible for the traffic accidents he causes．
Why is identity theft becoming so common？（37）GAnd the wealth of personal details people post on social networks such as Facebook also makes it easier for identity thieves to obtain personal information．
Many people are not aware of the problems caused by this crime．They wake up from their carefree attitude only when they become a victim and suffer the damages caused by this crime．（38）DAnd this is why it is important that every person should become cautious when using the Internet．The following tips may prevent you from identity theft．
First，make sure your computer has an updated anti-virus and firewall system installed．Second，only enter your credit card details on secure sites，or websites that you've used before．Third，（39）F Your date of birth，names of schools attended，phone number or the names of your parents are often required to verify （证明） an identity，and thieves can use this information too．Fourth，avoid sharing files as this gives other people access to your hard drive．Fifth，never open suspicious e-mails from unknown source．Last but not least，create complex passwords using a combination of numbers and keyboard symbols．（40）C

A．There is one solution to the problem．
B．He may borrow money from the bank in your name．
C．And change your passwords on a regular basis．
D．There is no cure for identity theft except prevention．
E．You must pay off all your debts ahead of time．
F．Avoid giving away too much personal information on social networking sites．
G．The popularity of the Internet and computers provides a gateway （出入口） for the identity theft．
13．Any car accident is frightening，but an accident in which your vehicle is thrown into the water，with you trapped inside，is absolutely terrifying．（32）DHowever，most deaths result from panic，without a plan or understanding what is happening to the car in the water．By adopting a brace position （防冲击姿势），acting decisively and getting out fast，you can save yo urself from a sinking vehicle．
Brace yourself for impact．As soon as you're aware that you're going off the road and into a body of water，adopt a brace position．The impact could set off the airbag system in your vehicle，so you should place both hands on the steering wheel in the"ten and two"position．
Undo your seatbelt．（33）FUnbuckle the children，starting with the oldest first．Forget the cellphone call．Your car isn't going to wait for you to make the call．（34）ALeave the door alone at this stage and concentrate on the window．A car's electrical system should work for up to three minutes in water，so try the method of opening it electronically first．Many people don't think about the window as an escape option either because of panic or misinformation about doors and sinking．
Break the window．If you aren't able to open the window，or it only opens halfway，you'll need to break it with an object or your foot．It may feel counter-intuitive （有悖常理的） to let water into the car．（35）GEscape when the car has equalized．If it has reached the dramatic stage where the car cabin has been filled with water and it has become balanced，you must move quickly and effectively to ensure your survival．（36）CWhile there is still air in the car，take slow，deep breaths and focus on what you're doing．
 
A．Open the window as soon as you hit the water．
B．Surviving a sinking car is not as difficult as you think．
C．It takes 60 to 120 seconds for a car to fill up with water usually．
D．Such accidents are particularly dangerous due to the risk of drowning．
E．In conclusion，if you know what to do in the water，you'll be safe．
F．This is the first thing to attend to，yet it often gets forgotten in the panic．
G．But the sooner the window is open，the sooner you can escape directly through it．
