14.General Airport Tips
Plan to get to the airport at least an hour early,or two during holidays and other busy times; this will reduce the stress of the flight.If all goes well,you will have time to relax,shop for last-minute items,or have a meal before the flight.
Flight Delays
Find out why your flight is delayed.Call the free call numbers.Find out if other airlines are experiencing similar delays.If you believe the delay is due to something other than weather or air traffic problems,then mention your suspicion (怀疑) and ask the airline agent to book you on the next available flight,either on the same air-line or a competing one.This is called"Rule 240",and all airlines are required to do it.Use the lingo (行话); ask,"Can you 240me?"when speaking with an agent.They will know what you mean.

19.Recently some articles state that the word‘‘selfie"has become one of the most annoying words.But I'd like to offer that maybe it is not so bad.The"selfie"is used to describe the self-taken photo,often from a smartphone.Women and men decorate their Facebook,Twitter,and Instagram accounts with these pictures,sometimes with puckered (翘起) lips or large smiles.In fact,the selfie has become so widely known that over 31million photos on Instagram are taken with the selfie.
Let's think about it.Someone takes about 10selfies each time they do,and they only end up posting one or two of those.They pick the one that makes them look the best.Isn't that beautiful?In that one picture,someone has given himself or herself confidence.Self-image is important.In society today,we are so often consumed with what society tells us is perfect.But maybe,with that one selfie,we feel that we fit that bill.We feel handsome,beautiful,confident,smart,happy and content.For that moment,everything bad or terrible that has ever happened to us is erased,because that smile or that pucker is what gives us the determination to love ourselves.
I saw a spoken word poem recently and the young man said:If I ask you what you love,the answers will most likely roll off your tongue.You love to read.You love to write.You love birds,music,your mom,your brother,your sister,your daughter,your best friend,your dog.How long do you think you could go on and on before you said"I love myself"?
That statement hit me like a ton of bricks.I've struggled with confidence all of my life.I still do.And in no way am I saying that taking a selfie is a gateway to that confidence.However,the selfie does deserve some credit for allowing individuals to express themselves.Pamela Rutledge agrees,stating,"There are many more photographs available now of real people than models."

52.According to the author,selfieC.
A.is an annoying habit for people
B.becomes a fashion among teenagers
C.gives a person a sense of confidence 
D.makes a person become self-centered
53.The author mentions a poem in the passage to stressD.
A.the power of true love 
B.the endless love we get
C.the kinds of love we have 
D.the need to love ourselves
54.What Pamela Rutledge said in the last paragraph suggests thatD.
A.selfie causes models to be out of work
B.selfie gets models to take more photos
C.selfie helps more people look like models
D.selfie provides more photos of real people
55.The best title for the passage isA.
A.The Value of Selfie 
B.The Origin of Selfie
C.Selfie Causes Bad Effects 
D.Selfie Creates Beauty.

16.
Homonym:a word that has the same spelling and the same pronunciation as another world,but a different meaning
Same spelling,different meaning
Imagine,then a situation where two words are spelt and pronounced exactly the same way,but have completely different meanings.Welcome to the world of homonyms.Take,for example,the word‘fail'---it can be a kind of festival,and adjective to describe the color of your hair or how you should play a game.
Don't take it literally
So how do you know which meaning someone is referring to?---You don't,except by the context.Obviously,if someone asks you to‘give them a hand',they don't want you to remove what is at the end of your arm.
What's in a name?
Sometimes even the context doesn't help much---the result can be amusing.These sentences play with the double meaning of a noun:
I used to be a banker,but I lost interest.
Have you heard about the cross-eyed teacher who couldn't control his pupils?
A small boy swallowed some coins and had to go to hospital.When his grandmother phoned to ask how he was,the nurse said:‘No change yet'.
More ambiguity
And these examples play with the different meanings of a verb:
I wondered why the ball was getting bigger.Then it hit me.
No one knew she had a dental implant until it came out in a conversation.
A boiled egg in the morning is hard to beat.
Double trouble
And sometimes a word can be a noun and a verb,but have different meanings.Can you work this one out?
Time flies like an arrow.Fruit flies like a banana.
If you like these homonyms,you will be pleased to know that English has plenty more!
Explanations of jokes in the text
I used to be banker,but I lost interest.(I became bored with the job/I lost money)
Have you heard about the cross-eyed teacher who couldn't control his pupils?(students/parts of his eyes)
A small boy swallowed some coins and had to go to hospital.When his grandmother phoned to ask how he was,the nurse said:‘No change yet'.(no difference in the situation/no money)
I wondered why the ball was getting bigger.Then it hit me.(the ball hit me/I suddenly realized)
No one knew she had a dental implant until it came out in a conversation.(became known/fell out)
A boiled egg in the morning is hard to beat.(can't be better/difficult to mix with a fork)
Time flies like an arrow.(time goes quickly) Fruit flies like a banana.(insects enjoy eating fuit.)
56.Which of the following statements about homonyms is NOT true?D
A.They share the same spellings regardless of meanings.
B.We can't know their meanings without context.
C.We may still feel confused even with context.
D.Their ambiguity brings great trouble to our life.
57.The"beat"in the sentence"A boiled egg in the morning is hard to beat,making for a satisfying breakfast."has a similar meaning toB.
A.The rain was beating down on the tin roof.
B.Taking the bus sure beats walking.
C.The doctor could feel no pulse beating.
D.You've been working too hard,you look dead beat.

13.The Horn of Plenty is one of the largest natural health food stores within the Greater Hamilton area.We are big supporters of buying locally and we are here to tell you why it is so important for   your family,the community and the environment.The concept of buying locally is simple:buy food produced,grown,or raised as close to  your home as possible.Not only will your food be fresher and tastier,but you are helping protect the environment and are supporting businesses within your community and reducing pollution.
Better for the environment
Sustainabilityand global warming are such hot topics at the moment,and  many                 people want to do their bit to help support a healthier environment.Small action carried  out by many people can make a big difference.Most materials in an average North      American meal have traveled about 1,500 miles to get from farm to plate.To cut out a big part of this travel would greatly reduce not only pollution from transportation and       refrigeration but also customers'expenses as well.
Taste and nutritional content
Locally-grown fruits and vegetables are usually sold within 24 hours of being harvested.Because they are picked at the height of ripeness(成熟) and travel only a short distance to the market,their freshness,nutrition,and flavor are kept.Produce trucked in from far away may lose both taste and nutritional content.Community and home values
When you buy direct from a farmer or buy locally-grown foods,you are engaged in a    time-honored tradition between a grower and an eater.You also help keep dollars within your community.
21.It can be inferred from the third paragraph thatC.
A.global warming is the most serious problem now
B.North American food is rich in various kinds of materials
C.the increased cost of transporting food is passed on to the customers
D.most people support buying locally
22.Locally-grown fruits and vegetables taste good mostly becauseA.
A.they are picked when they are fully grown
B.they are not polluted by chemical fertilizer
C.they can be harvested at any time
D.they are sent to the market at a high speed
23.According to the author,when you buy locally-grown foodsB.
A.you can see how fruits and vegetables grow
B.you will contribute to protecting the environment
C.you will become much healthier and prettier
D.you are making money from your community
24.What does the passage mainly talk about?D
A.The way to keep your food tasty and healthy.
B.The popularity of the Horn of Plenty.
C.The importance of protecting the environment.
D.The benefits of buying locally.
