13.Tips for Staying Sharp
It's not abnormal to feel out of it from time to time or perhaps you're feeling a bit sluggish(迟钝的)when it comes to remembering things.If you're worried about your forgetfulness,try out these five tips to stay sharp.
(36)A
You've probably heard the term"you are what you eat."If you decide to eat sugary foods that are heavy with fats then expect to feel lazy and have no energy.But if you decide to eat fruits,vegetables and make other healthy eating decisions you'11find that you're full of energy.
Never stop learning
Challenge yourself constantly-whether it is puzzles,reading,cooking or other tasks that will keep your mind working.If your mind is always learning new things and active,you'11realize that it's much easier for you to learn new things and to function.(37)G
Stay fit
Being in good health and staying in shape is a big part of staying sharp.(38)CIf you choose to be lazy then your body is not going to give you the energy that requires remembering things and completing tasks.However,if you put forth the effort into being healthy then your body will expel(释放)the energy you need to achieve your goals.
Ensure enough sleep
Be sure to get the necessary amount of sleep that your body needs to function on a daily basis.(39)FIt also helps your body build up an energy reserve so you can improve your ability to focus and avoid distractions.
Socialize more
(40)E Social interaction will help you develop multitasking,problem solving and other skills that are necessary in life to keep your mind sharp.

A.Feed your brain.
B.Avoid eating too much.
C.Your body will only give you what you put into it.
D.Lack of sleep contributes to tiredness and slow reaction.
E.Conversations require individuals to stay aware and active.
F.According to studies,sleep helps strengthen and recover your memories.
G.Remember your brain is a muscle and if you want to get the most out of it,you must use it.

3.Do you love holidays but hate the increase of weight that follows?You are not alone.
Holidays are happy days with pleasure and delicious foods.Many people,however,are worried about the weight that comes along with these delicious foods.
With proper planning,though,it is possible to control your weight.The idea is to enjoy the holidays but not to eat too much.You don't have to turn away from the foods that you enjoy.The following suggestions may be of some help to you.
Do not miss meals.Before you leave home for a feast,have a small,low fat snack.This may help to keep you from getting too excited before delicious foods.
Begin with clear soup and fruit or vegetables.A large glass of water before you eat may help you feel full.Use a small plate; a large plate will encourage you to have more than enough.
Better not have high fat foods.Dishes that look oily or creamy have much fat in them.
Choose lean meat.Fill your plate with salad and green vegetables.
If you have a sweet tooth,try mints(薄荷)and fruits.They don't have fat content as cream and chocolate.
Don't let exercise take a break during the holidays.A 20 minute walk after a meal can help burn off extra calories.

4.I(61)have traveled  (travel) to many places since I went to college.(62)What   impressed me deeply was my travel to Tibet last year.I took the train there with my friends and enjoyed the scenery all   (63)the  way.When the train was close to Tibet,I had a headache.Then I found(64)it difficult to breathe and felt

1.Where would we be without the Internet?We certainly wouldn't be at once messaging someone we met six years ago.We also wouldn't be able to form a sentence using only symbols like J or L.Before the Internet came into being,there was no such thing as"unfriending"someone.
We no longer require homes,bars,offices or cafes to keep in touch with people.We can do it wherever we happen to be.This leads to some questions.When we connect to our devices,are we not connecting from the people around us?Are we hiding behind a screen from the physical world and becoming anti-social in turn?While there is a sense of panic about how the Internet is damaging communication,there are also lots of people who believe that it is actually making our friendships better.For better or worse,here are a few of the ways the Internet is changing the way we communicate.
Online relationships.Online dating becomes cool---it removed the embarrassment of forever-alone sitting at home imaging long walks on the beach and candlelit dinner.According to The New York Times,about 50million people use Tinder every month.Outside of Tinder,online dating has increased rapidly on platforms like RSVP and OKCupid.Gradually,dating online is just like meeting someone at a bar these days.
Everyone is an expert.The blogger vs.journalist debate has been very hot lately.While blogs are seen by their readers as an authentic channel of communication,bloggers'knowledge is often called into question by those,a journalist,for example,who have taken a more traditional route to get where they are.Thanks to the Internet,anyone with a keyboard can say anything they want.On the other hand,online blogs have given rise to voices that may never have been heard otherwise.
Social media.It has made us communicate with a much greater number of people globally that used to only be working on a local level.While this is great when it comes to keeping friendships alive over great distances,it also increases the demands on people to keep a much larger number of relationships going at the same time.Social media is a great tool,but if you find yourself looking through Facebook while you're at a dinner party or hanging out with others,it may be time to reconsider your relationship with the Internet.
No matter what your opinion about whether the Internet has changed communication for worse or better is,there's no doubt that it plays a major role in our lives today.So make sure you keep up with the latest technologies.
The Internet Is Changing Our (71)Communication.
(72)Withoutthe Internet*We wouldn't be messaging someone (73)instantly/immediatelywho we met six years ago.
*Before the (74)existenceof the Internet,there was no such thing as"unfriending"someone.
With the InternetThis leads to several questions.
*When we connect to our devices,are we (75)disconnecting/withdrawingfrom the people around us?
*Are we hiding behind a screen from the physical world and become antisocial in turn?
*Still many people believe that in fact it is (76)improvingour relationships.
The changes in the (77)approachesto communication*Online relationships.
Dating online is becoming as (78)commonas meeting someone at a bar these days.
*Everyone is an expert.
The blogger vs.journalist debate has been very hot lately.
*Social media.
It has (79)enabled/allowed us to communicate with a much greater number of people globally.
ConclusionIt is not (80)doubtfulthat the Internet plays a major role in our lives today.

5.A Particular Sign That Struck Me     I was driving around downtown one afternoon in the winter making a few deliveries.I was listening 
to a band,cruising (漫游)around,and minding my own business…
     I came up to a red light and stopped…waited.As I looked over to my left,I saw a young guy 
standing there.He was holding a cardboard sign with some writing on it.
     As with most major cities,when you're in the heart of downtown,it's pretty common to have 
homeless people on every other corner,holding a cardboard sign with something written on them-asking 
for money.I suppose after so many years,one can easily get desensitized (不敏感)to this sort of 
thing.In general,you see the person,read the sign if it's short enough,and make a decision that you 
don't want to go through the trouble of giving them money,or you tell yourself that they don't look like
 they're in need of money,or some other decision or thought goes through your mind.There are 
hundreds of thoughts and excuses out there…and we've all come up with them before.
     I looked at this gentleman,skimmed over the sign,but this time,I stopped.My mind went blank 
from all the hustle (忙碌) of the day,and work,and how I had to hurry,and where I had to go next,
and what I was doing that night,and how much money I needed to come up with and so on…The world 
stopped for a brief moment.I can't remember what the sign said exactly but it was something like:
"Need money/food,have stomach cancer,homeless,anything helps.God bless."
     The light turned green,traffic moved forward,and I went with it.About a block or two away,my 
heart had simply sunk for this guy.I knew I probably couldn't really help him,but I had to see if nothing 
else,maybe I could buy him lunch.So I turned around to go back and ask him if I could buy him lunch,
talk to him and hear his story.
     It took me about five minutes to get looped (绕圈) around and back on to the same street where I
 had seen him.It was just five minutes---but he was gone.

41.When did the author meet the young man?A
A.He was busying sending goods.
B.He was going home after work.
C.He was planning to have lunch.
D.He had nothing to do but listen to music.
42.The third paragraph tells us thatA.
A.some people pretended to be homeless to beg money
B.people have already become insensitive to the homeless
C.people have prepared many excuses to deal with troubles
D.people usually pretended not to see the homeless
43.After seeing the sign of the young man,the authorC.
A.found it nothing unusual at all
B.thought of many ways to help him
C.seemed to be seized for a while
D.felt sorry for being unable to help him
44.Why did the author drive back to find the young man?D
A.To encourage him to fight against cancer.
B.To find out why he suffered from cancer.
C.To share stories with each other.
D.To buy a meal for the young man.
45.What does the author expect to show by telling his story?C
A.People are heartless to the homeless now.
B.We shouldn't believe the story of a stranger at once.
C.Don't hesitate to show care and love to the homeless.
D.We shouldn't be afraid of getting into the trouble of giving strangers money.
