【题目】语法填空（每小题1分，共10分）
Do you like trying different things? Are you afraid 1 things that you think you’re bad at?
Last year I started to learn t’ at chi in order to improve my health and reduce my stress. It was something new for me, and I found it to be quite difficult, very 2 (difference) form anything I’d ever learned before. Small 3 (move) are important in t’ ai chi. I was used to being fast and active , 4 to learn t’ ai chi I had to learn patience. Now I’ve found that I’m a much more patient person than before, and t’ ai chi isn’t nearly as difficult as it 5 (be ) before.
We tend 6 (like) things we are good at — that’s normal. For example, I’m naturally very good at badminton and tennis, but I’m very had at anything 7 involves keeping balance, such as skating, skiing and gymnastics. T’ ai chi has 8 (great) improved my balance which has been a very good thing for me.
My point is that you can keep 9 (do) the things you know you’re good at and live in your comfort zone, or you can try something new. If you don’t try new things, you’ll never know what it would be like to try something new. Challenge 10 (you). It will definitely pay off in the end.

【题目】B
I am a good mother to three children. I have tried never to let my profession stand in the way of being a good parent. I no longer consider myself the center of the universe. I show up. I listen. I try to laugh. I am a good friend to my husband. I have tried to make marriage vows(誓约) mean what they say. I am a good friend to my friends, and they to me. Without them, there would be nothing to say to you today.
So here's what I wanted to tell you today: Get a life. A real life, not a desire of the next promotion (提升), the bigger paycheck, the larger house.
Get a life in which you are not alone. Find people you love, and who love you. And remember that love is not leisure (空闲); it is work. Pick up the phone. Send an email. Write a letter. And realize that life is the best thing and that you have no business taking it for granted.
It is so easy to waste our lives, our days, our hours, and our minutes. It is so easy to exist instead of to live. I learned to live many years ago. Something really bad happened to me, something that changed my life in ways that, if I had my choice, it would never have been changed at all. And what I learned from it is what, today, seems to be the hardest lesson of all:I learned to love the journey, not the destination. I learned to look at all the good in the world and try to give some of it back because I believed in it, completely and totally. And I tried to do that, in part, by telling others what I had learned.
By telling them this: Read in the backyard with the sun on your face. Learn to be happy. And think of life as a deadly illness, because if you do, you will live it with joy and passion(激情) as it ought to be lived.
【1】The best title of this passage probably ________.

【2】 How did the author form her view of life?
A. By working and social experience.
B. By learning from her friends.
C. Through an unfortunate experience.
D. From her children and husband.
【3】 The underlined sentence “It is so easy to exist instead of to live.” in the fifth paragraph probably has the same
meaning as “________”．
A. it is so easy to keep alive but not to live a real life
B. it is very hard to live a real life
C. it is so easy to make a living
D. it is more difficult to exist than to live a happy life
【4】 What's the author's attitude toward work?
A. Do it well to serve others.
B. To earn enough money to make life better.
C. Try your best to get higher position and pay.
D. Don't let it affect your real life.

Five Ways to Improve Communication Skills
Communication is one of the most important skills we can ever learn. It affects everything that we do — whether we’re communicating at work to meet deadlines and achieve results, or communicating with friends, family and partners to build strong relationships. Thus communication is very important. Here are five ways to improve your communication skills.
1
This reflects a real lack of respect. By interrupting someone, what you’re basically saying is ＂I don’t care what you’re saying — what I have to say is more important＂.
Don’t finish other people’s sentences.
2 Wrong. Research has shown by doing this you are disempowering the other person because you are taking control of the conversation, so bite your tongue!
Paraphrase.
If you want to show that you have really understood someone, then paraphrasing(解释) is a great tool. ____3____ Here’s an example: ＂So Barney, what I’m hearing is that results are the number one objective for you right now and we need to find some fast solutions for you?＂
4
Focus on active listening instead of passive listening. The difference is that active listening means you engage with and respond to the other person based on what he/she has said, while passive listening is simply the act of listening with no response.
Maintain eye contact.
By looking at the other person in the eyes, you are proving that you’re interested in what he/she is saying. ____520____
A. Talk actively.
B. Listen actively.
C. Never interrupt people.
D. This also keeps you focused and less distracted.
E. You don’t see them interrupting others or leaving off mid-conversation.
F. I used to do this a lot thinking I was helpfully finishing people’s sentences for them.
G. All you do is repeat back to someone what he/she has just said, before you comment yourself.
