1.It looks exactly like other handicraft (手工艺品) shops in a traditional Chinese hutong,or alley,except that each item has a story.The city's first-of-its-kind charity shop,owned by Nathan Zhang,sells Chinese handicrafts along with used books,clothes and other items.The concept is that money from what is sold is donated to help rural (农村的) women in China.
"Many NGOs (non-governmental organizations) produce their own things but don't have a place to sell it,"said Zhang,who returned to Beijing in 2008 after working in Canada for nearly a decade in the telecommunications world."A rural women's group tried to open a little shop but only sold two things.When they put their products in my shop,everything sold out."
Located in Wudaoying Hutong in Dongcheng district,Brand Nu's walls are lined with handicrafts from a number of different NGO supported projects aimed at benefiting women across the country.The other half of the space is filled with almost brand-new clothes that have been donated from Beijing citizens.The jackets,dresses,tops and pants sell for around 30 yuan ($4.40)each.
Most of the money Brand Nu gets goes directly to the Beijing Cultural Development Center for Rural Women.The NGO offers a number of programs for poor women,including literacy classes (识字班),support networks and mental health education.
Zhang is also working with a local Scottish designer to create a clothing line made from the fabric (织物) of second-hand garments.And he is collecting books and raising money to help the NGO build a library near Beijing.He plans on expanding his product line soon as well,engaging more disadvantaged women to make sweaters,soaps and other items that he can sell in Beijing to help raise their socioeconomic status in the countryside.
Yet with ambitions come worries.Right now Zhang is operating on a shoestring budget and looking for work on the side to support both his business and his family."I wanted to do something meaningful,"said Zhang."If you can help one woman,you can help an entire family."

2.What makes a person a scientist?Does he have ways or tools of learning that are different from those of others?The answer is"no".It isn't the tools a scientist uses but how he uses these tools which makes him a scientist.You will probably agree that knowing how to use a power is important to a carpenter.You will probably agree,too,that knowing how to investigate,how to discover information,is important to everyone.The scientist,however,goes one step further;he must be sure that he has a reasonable answer to his questions and that his answer he gets to many questions is into a large set of ideas about how the world works.
The scientist's knowledge must be exact.There's no room for half right or right just half the time.He must be as nearly right as the conditions permit.What works under one set of conditions at one time must work under the same conditions at other times.If the conditions are different,any changes the scientist observes in a demonstration must be explained by the changes in the conditions.
This is one reason why investigations are important in science.Albert Einstein,who developed the Theory of Relativity,arrived at this theory through mathematics.The accuracy of his mathematics was later tested through investigation.Einstein's ideas were proved to be correct.A scientist uses many tools for measurements.Then the measurements are used to make mathematical calculations that may test his investigations.
13.What makes a scientist according to the passage?C
A.The tools he uses.            
B.His ways of learning.
C.The way he uses his tools.     
D.The various tools he uses.
14."…knowing how to investigate,how to discover information,is important to everyone."The writer says this to showC.
A.the importance of information
B.the difference between scientists and ordinary people
C.the importance of thinking
D.the difference between carpenters and ordinary people
15.What is the main idea of the passage?D
A.Scientists are different from ordinary people.
B.The Theory of Relativity.
C.Exactness is the core of science.
D.Exactness and way of using tools are the keys to making of a scientist.

13.Hello.I'm Jan from Mrs.Lake's class.My class wants to work together to help the public.We think we have found a great way to do this.Last month we did a class project on the highways near our town.We learned about the Adopt-a-Highway Program.This program brings people together to pick up litter along the roads.We think it would be a great idea for all students in our school to join the program and adopt a highway.
    Adopting a highway is not like adopting a pet.When a highway is adopted,only part of the highway is cared for by a group of people.The group agrees to work every week to keep its part of the highway clean.Each group gets its own sign that has the name of the group printed on it.The sign is put up at the side of the road.This sign lets drivers know who is keeping that area of the road clean.
    The Adopt-a-Highway Program is a great way for people to help their environment look nicer.Also,the governwent does not have to send out as many road workers.This saves money.Finally,people may try harder to keep roads clean if they see people,especially teenagers like us,cleaning them up.
    We will need helpers to care for our adopted highway.If you want to feel great and keep our roads clean,please come with your parents to the meeting next week.We will meet in Mrs.Lake'room on Wednesday at 6:00 P.M.At the meeting,we will talk about which roads are the dirtiest as a result of people's unkind acts.Then we'Il try to pick an area to adopt and clean ap.
   I look forward to seeing you at the meeting.Remember to keep our roads clean!
21.What is the Adopt-a-Highway Program about?C
A.Giving names to the highways
B.Drawing pictures of highways.
C.Picking up litter along the roads
D.Putting up signs near the roads.
22.What should the students do first if they want to join the program?D
A.Pick a spot to care for.
B.Call Mrs.Lake next week.
C.Write a letter to their parents.
D.Go to a meeting on Wednesday.
23.What is the purpose of this speech?A
A.To encourage students to join the program.
B.To introduce the traffic system.
C.To show drivers how to drive safely.
D.To tell a story about adopting a pet.

14.When we talk about intelligence,we do not mean the ability to get good scores in certain kinds of tests or even the ability to do well in school.By intelligence we mean a way of living and behaving,especially in a new or anxious situation.If we want to test intelligence,we need to find out how a person acts instead of how much he knows what to do.
For example,when in a new situation,an intelligent person thinks about the situation,not about himself or what might happen to him.He tries to find out all he can,and then he acts immediately and tries to do something about it.He probably isn't sure how it will all work out,but at least he tries.And,if he can't make things work out right,he doesn't feel ashamed that he fails; he just tries to learn from his mistakes.An intelligent person,even if he is very young,has a special outlook(人生观) on life,special feeling about life,and knows how he fits into it.
If you look at children,you'll see great difference between what we call"bright"children and"not bright"children.They are actually two different kinds of people,not just the same kind with different amounts of intelligence.For example,the bright child really wants to find out more about life-he tries to get in touch with everything around him.But the unintelligent child keeps more to himself and his own dream-world; he seems to have a wall between him and life in general.

51.This passage mainly tells us that intelligence is the abilityD.
A.to do well in school   B.to behave immediately
C.to know what to do    D.to deal with life
52.In a new situation,an intelligent personB.
A.knows more about what might happen to him
B.concentrates on the situation
C.is sure of the result he will get
D.cares more about himself
53.In the author's opinion the biggest difference between"bright"children and"not bright"children lies inC.
A.the amount of intelligence       B.the different situations they face
C.the different attitudes to life  D.the background of life
54.What's the main idea of the passage?A
A.What's real meaning of intelligence?
B.What's the"bright"children's behavior?
C.What's a special outlook on life?
D.How to live and behave in a new situation?
55.What might the author continue to talk about in the passage that follows?B
A.how to determine what intelligence is
B.how an unintelligent person should be taught
C.how to judge whether a person is intelligent
D.how education should be changed.
