When I first started Grade 7, I was shy and did not dare to speak to anyone. My English was not very good and I felt nervous when I had to answer questions in class. I would have problems speaking even though I knew the answer. I felt quite unhappy with myself.
One day, Mrs. Wang spoke to me after class. She encouraged me to speak slowly. She also told me that she believed I could speak well if I practice more. I was touched by what she said and it made me work harder on my speaking skills.
Mrs. Wang continued to encourage me and I became even more confident. I improved so much that I won an English speech contest that year! I will always be grateful to Mrs. Wang for her advice and support.{九年级上册英语长江作业本}.

I first started playing the piano when I was three. My parents are musicians, so they were both very encouraging. It was their dream, I think, to raise a child who could one day become a world-class pianist. So they asked an expensive personal teacher to teach me, and I practiced every day, sometimes for five or six hours at a time. Despite(尽管)the long hours and frustration(挫折), I did enjoy it, especially at first, and I was good. According to my parents and my teacher, I was really excellent, and I was on the road to becoming a professional musician, just
like my mother and father.
The trouble was, my head really wasn't in it. My real interest was something quite different—mathematics(maths). Numbers were the things that really shone brightly in my mind. I found more beauty in a mathematical equation(相等), I told my parents, than in a piano sonata(奏鸣曲). So when I went to college, I chose to study mathematics, not music. Then I got a job, working as an accountant.
Now I work with numbers every day. My parents couldn't understand, and even now I guess they are still angry with me. They say I wasted a special gift. But I still believe what I did was right for me.
1.It cost the writer's parents a lot to ________.
A.help him with his lessons
B.raise their son to be an excellent pianist
C.become professional musicians
D.practice playing the piano
2.At first what the writer did showed that ________.
A.he was hopeful in music
B.he hated playing the piano
C.he didn't have a gift for music
D.he liked mathematics better
3.The writer's parents felt very sorry for their son because they thought ________.
A.his heart wasn't really in music
B.they didn't like his job of an accountant
C.he wasted a special gift
D.he didn't realize his mistake
4.Which is the best title of this story?
A.Nobody Understood Me
B.The Road to My Career
C.My Parents' Dream
D.Don't Be Sorry for Me

Matt Mason has seen the future—and it's fun. Mason likes thinking about how machines can make our lives easier by doing the work we hate, such as cleaning. He shows a hard floor cleaning system(系统)that's built into the wall: it will blow dirt to a part of the room where it will be collected by a vacuum(吸尘器). Then the system will drop some cleaner on the floor and an
arm will mop(用拖把擦)it up. “This may trouble you,” says Kara, an expert in Mason's company. “But you can program it to come on at 3 a. m., and it will just wet-mop the floor for you.”{九年级上册英语长江作业本}.
When it comes to the kitchen, Bruce Beihoff, another expert at Whirlpool, is sure that in a few years, robots will be doing most of the boring work, freeing us to relax. “More than just fun, future kitchens will be environmentally friendly,” he says. “A new system will be built in the house which can recycle energy(能量)lost from your kitchen to make the whole home warm.”
“The fridge will be the center of the home,” says Daniel Lee, a market expert. The fridge will have a touch screen(触摸屏幕)where you can watch TV, surf the Internet, check your e- mail, keep a shopping list and order vegetables. “Your fridge is the first place you go in the morning and the last place at night,” says Lee.
Ever wonder why a 1.9-meter man and a 1.6-meter woman have to cook meals on counters(工作台)of the same height. “The height was decided over 50 years ago, according to the height of ordinary women,” says Jane Langmuir, an expert of cooking machines. “But times have changed. We have made a new counter where you press a button and it moves to whatever height you want.” At the same time, Ted Selker at MIT's Counter lab has made the Dishmaker which lets you make dishes and bowls out of plastics at home. After each meal, the dishes are changed straight back into plastics.
1.How many inventions are mentioned in the passage?
A.Three. B.Four. C.Five. D.Six.
2.In future, if you want to clean your house, you will ________.
A.have a recycling system built in the wall
B.get up early to start your cleaning system
C.use your fridge to give orders to a cleaner
D.leave the work to a kind of cleaning machine
3.What is future kitchen work like?
A.Terrific and relaxing. B.Easy and interesting.
C.Enjoyable and exciting. D.Funny and amazing.
4.From the passage, we know ________.
A.people will have more and more time enjoying themselves
B.future kitchens can provide all the energy for our life every day
C.the fridge can be found in the center of a future house{九年级上册英语长江作业本}.

四、完形填空
Mr. Klein told the class that a new student, Inez, would join them soon. He that Inez was deaf. She “talked” with others by using sign language. Mr. Klein knew sign language, and he decided to teach students so that they could also “talk” with Inez.
First, they learned to sign the letters. Some letters were hard to . Other letters, such as C, were easier because the shape(形状)of the hand was the same as the shape of the letter.
The thing they learned was fingerspelling. They signed one letter after another to spell a word. They with two-letter words such as ‘at’ and ‘on’. Then they spelled words.
Finally, Mr. Klein showed that one sign could be used for a whole word. To make
