A
For a long time being happy was considered something that just happened, and there was nothing special about it. Now we know that getting along with other people is something that we can work at. It is possible to act in such a way that other people will like us better. One way is being unselfish, not wanting everything from our friends. Another way is to look for good points, not bad ones in other people. It is surprising how successful this treasure hunt can be. You don’t have to be spineless(沒有骨氣的.) in order to be popular. In fact, you will be liked and respected if you are not afraid to stand up for your rights. But do it politely and pleasantly. Being friendly and polite to your group, to other people and to strangers and especially to those who do not look important or do not interest you is one way to develop a good character. You can not expect to be perfect, and you must learn not to be unhappy when you make mistakes. Everyone makes mistakes, and no one is to be blamed unless he refuses to learn from them. Many young people become discouraged when they know in themselves qualities that they do not like—selfishness, laziness, and other unpleasant qualities. Just remember that we all have some of these faults and have to fight against them. At the same time, it is important to remember that, while you are probably no worse than others, the best way to be happy is to think yourself above other people. When something is wrong, it is good sense to try to make it right. Perhaps you don’t like a teacher or a classmate. Try to see why and look at yourself, too, to be sure that you are not doing anything to make that person dislike you. Some day, things may turn out all right and then you will have to learn to get along the best with situation, without thinking too much about it. Worrying never helps in a situation you can’t change. 21. According to the passage, if one wants to be popular he has to _____. A. be polite and friendlyB. give up some rights C. avoid arguing with other peopleD. be ready to change his or her character 22.The passage shows that there is no perfect person but everyone should be blamed if he _____. A. is no better than others B. is selfish and lazy C. does not draw a lesson from his own fault D. is very happy about his unpleasant quality .The passage implies that in order to be a happy person, one should consider oneself _____. A. no better than others B. not the same as others C. as having something better than others D. as having better chances than others .The purpose for the writer to write the passage is to _____. A. train you to be perfect B. show you the way to be happy C. tell you how to act when you dislike a person D. teach you how to be popular among your friends

Teamwork is all about working together to achieve a common goal or purpose. Is teamwork out of date?Why is it so hard to effectively conduct teamwork in those days?
One way we employ teamwork in everyday lives is by becoming a parent. It is parents’ job to teach their children the basic skills and give them the knowledge they need to be successful in life. This，to me，requires teamwork. For example，the mother teaches her children manners and good health skills，while the father teaches them how to catch a ball or drive a car. However，in today’s society，we find that more and more parents are feeling that this teamwork is a one-sided thing. According to a report，there are 13.7 million single parents raising their children in the US and this could be due to the fact that parents don’t take responsibility for their children，so they leave one parent to do it alone. This is a sad fact，and it reflects that effective teamwork is losing ground in the parenting aspect of our everyday lives.
Another place where teamwork affects us greatly is in our jobs. It doesn’t matter if you have a small company or a large company：if you have at least one employee and yourself，then teamwork works. I have noticed that with the current economic recession(衰退)，people are racing to grab jobs but the quality of people’s work has gone down greatly. It just appears to me that people do not take pride in their work any more. They get to work as fast as they can，just to receive the paycheck，but their quality standards fly right out of the windows. So I think teamwork is losing ground in the workforce.
As you can see，we run into the aspects of teamwork in just about everything we do. Do you believe teamwork is really losing ground in today’s society?I think it is.
28.Why does teamwork disappear in the parenting aspect of our daily life?
A.Parents have no time to spare for their children.
B.Parents have no chances to teach their children about it.
C.Many children are often brought up by a single parent.
D.Many children are independent to deal with their matters.
29.Teamwork is losing ground in the workforce mainly because .
A.workers don’t like to work together with others
B.workers’ sense is affected by economic recession
C.workers want to prove they are more capable
D.fewer workers are employed to save money
30.The author wants us to believe his opinion by .
A.listing some data
B.giving some examples
C.asking some questions
D.analyzing some cases
31.The underlined phrase “fly right out of the windows” in Paragraph 3 means “ ”.
A.disappear B.Improve C.increase D.matter
D
Around four years ago，I received a call from the principal of our school as to the “Parents View” talk the next morning. He asked me to speak to the group. After the call，my whole body became feverish and panicky. The time from his call to the next morning seemed like years. The whole night，I could not sleep with many ominous apprehensions in mind. One of them was to call the principal with regret and tell him that I could not come. Finally，I gathered some courage. I thought，“If I miss this opportunity，surely the school will never invite me again to any of their programs.”
I reached the school in time. Before my turn came，my whole body was trembling. When my turn came and I started speaking，my heartbeat increased and my mouth went dry. I wasn’t even able to read the written speech properly. I was not aware of where I was standing and what I was reading. That was the day when I realized my biggest weakness：Public Speaking.
After my speech，I met with the principal and explained what happened to me. He told me that this happens to everyone. Even great speakers faced the same things when they started. He suggested that I come again next time.
Around one month later，I was invited to refer to a topic on motivation. This time I was feeling comfortable. My speech was appreciated by the principal as well as the teachers，because I was able to get my idea across to them. They encouraged me and praised my efforts.
After delivering it successfully，I became more confident. I said to myself，“If I can speak in front of such a learned audience，like the principal who educates others，I can now speak in front of others too.”
I started delivering lectures on various topics like Self Motivation，Personality Development，Personal Excellence，Spoken English and Presentation Skills. This has become a passion for me. I have learned that everything is possible if we have the courage to take the first step.
32.Which of the following is the best title for the passage?
A.Practice Makes a Man a Better Speechmaker
B.Public Speaking Makes a Man Embarrassed
C.Principals Provide the Best Chances
D.Spoken English Develops in Making Speeches
33.The author had bad feelings before the speech because .
A.he disliked the idea of giving a lecture
B.he had got a high fever before that
C.he regretted accepting the invitation
D.he feared he couldn’t perform it properly
34.What does the underlined part “ominous apprehensions” in the first paragraph mean?
A.Unlucky opportunities. B.Negative ideas.
C.Curious views. D.Happy comments.
35.What can we conclude from the passage?
A.Nothing is to be got without pains but poverty.
B.Knowledge makes humble;ignorance makes proud.
C.A journey of a thousand miles begins with a single step.
D.Necessity is the mother of invention.

I work with Volunteers for Wildlife, a rescue and education organization at Bailey Arboretum in LocustValley. Trying to help injured, displaced or sick creatures can be heartbreaking; survival is never certain. However, when it works, it is simply beautiful.
我在“野生動物志愿者”組織工作，這是蝗蟲谷貝利植物園的一個援救教育組織，幫助受傷、流離失所或生病的動物。這樣的工作可能會令人心碎；因為無法確定動物是否能活下來。然而，當救援起作用時，這種感覺真的很棒！

f'(x)=2ax+(2-a)-1/x
=(2ax^2+(2-a)x-1)/x
=(2x-1)(ax+1)/x
a>1
令f'(x)>=0
x<=-1/a或x>=1/段拿態(tài)2
定義域是x>0
∴x>=1/2
增區(qū)間是[1/2,+∞),減區(qū)間是(0,1/2]
當1/a>=1/2時
f(x)在區(qū)間[1/a,1]內(nèi)的最大值
=f(1)
=a+2-a-0
=2不是ln3
∴握源1/a<1/2
a>2
f(x)在區(qū)間[1/a,1]內(nèi)的最大值
=f(1/敏坦a)
=a*1/a^2+(2-a)/a-ln(1/a)
=1/a+2/a-1+lna
=3/a-1+lna
=ln3
∴a=3符合a>2
綜上a=3
