11.请你根据所给提示,用英语写一篇短文,介绍微信(WeChat)的利与弊,并发表在校英文论坛上.
注意:1.词数100左右;
2.可适当增加细节,以使行文连贯.
More and more people are beginning to use WeChat and some have even become addicted to it.However,WeChat has both advantages and disadvantages.
WeChat really shortens the distance between people.No matter where we are,we can easily contact our friends.Besides,we can find friends to whom we can tell our secrets which we don't want our families to know.However,it also has disadvantages.First,some information offered in WeChat is false and it may result in people being cheated.Second,some people spend too much time on WeChat,greatly influencing theirnormal life.
Ithink WeChat is convenient but we should use it properly..

8.Travel can be stressful,so it is not unusual for airports to offer a room for relaxation.(41)But San Francisco Airport has taken(42)the idea one step further,offering a yoga room for passengers in need of a good stretch before their flights.
With blue walls and rule of silence,the room in Terminal 2(43)was desighed  (design) at the suggestions of a passenger during an open meeting.Airport yoga lovers arc directed to the room(44)by the usual means---a picture,one(45)that  features a figure (46)seated  (seat) in a full lotus position..
Airport director,John L.Martin,called the room,which opened last week,"another leap forward in providing our travelers with the opportunity and space to relax and reduce pressure on (47)their  own terms."
The architects set the lights low and warm,and constructed a floating wall(48)to symbolize (symbolize)"a light spirit and enlightened mind"
Yoga teacher,Tamal Dodge said,"How amazing it will be to stretch out(49)before  you get on a plane for a 12-hour flight!You are now given the opportunity to(50)really  (real) relax and prepare your body for something as tiring as sitting in an airplane scat for hours on end."

5.This is a perfect example (61)of what a positive person Anne was.Unfortunately,due to the rising popularity of Adolf Hitler and his ideas of how the world should be,on the morning of June 6th,1942,the Frank family was (62)forced (force) to go into hiding in a secret annex; Anne taking her few (63)possessions (possess),one of them was a diary she had received for her thirteenth birthday.Over the next few years,she devoted herself to this diary,not (64)knowing(know) that,many years later,it would provide inspiration for people all over the world.
Why I have always looked up to Anne Frank is not only (65)because she was an amazing author,which I have always wanted to be,but also because her writing (66)truly (true) reflected what a bright person she was.A particularly inspirational quote from her diary was-"I don't think of all the misery,(67)but of the beauty that still remains."This is all you really need (68)to hear(hear) to know what kind of person she was.Anne will never be forgotten because she never was (69)an ordinary girl.She was wise beyond her years,but kept (70)her (she) sense of fun through everything and had a talent for making people laugh.

12.I was standing in the checkout line behind a woman who looked to be in (21)her 60s.When it was her turn to pay,the cashier greeted her by name and asked her how she was doing.
The woman looked down,(22)shook(shake)her head and said:"Not so good."My husband just lost his job and my son is up to his old tricks again.The truth is,I don't know how I'm going to get through the holidays."
Then she gave the cashier food stamps.
My heart ached.I wanted to help but didn't know how.(23)ShouldI offer to pay for her groceries or ask for her husband's resume?
As I walked into the parking lot,I saw the womenreturning(24)(return)her shopping cart.I remembered something in my purse(25)thatI thought could help her.It wasn't a handful of cash or an offer of a job for her husband,but maybe it would make her life better.
My heart pounded as I approached the woman.
"Excuse me,"I said,my voice trembling a bit."I couldn't help overhearing what you said to the cashier.It sounds like you're going through a really hard time right now.I'm so sorry.I'd like to give you something."
I handed her the small card from my purse.
When the woman read the card's only two words,she began to cry.And through her tears,she said:"You have no idea(26)what this means to me."
I was a little startled by her reply.(27)Not having done(not do)anything like this before,I didn't know what kind of reaction I might receive.All left for me (28)to say(say)was:"Oh.Would it be OK to give you a hug?"
(29)Afterwe embraced,I walked back to my car--and began to cry,too.
The words on the card?
"You Matter."
A few weeks earlier,a colleague gave me a similar card(30)as encouragement for a project I was working on.When I read the card,I felt a warm glow spread inside of me.Deeply touched,I came home and ordered my own box of You Matter card and started sharing them.
