As we all know sewing-machine(缝纫机) repair is one of the fastest growing businesses in the world today.Newspapers,women’s magazines,high schools and colleges are all encouraging millions of American women to do their own sewing,not only to make their own shirts and sweaters,but also to make nice clothes for their husbands,sons,or boyfriends.The lates figures(数字) show that over 89 million American women,because of the high costs of ready-to-wear clothing are now making almost all of their families’ clothes.Most of these women get great satisfaction from making the family clothes on their own sewing machines.So it is natural that the demand(要求) for excellent service of sewing machines is growing.
Think of it! 89 million or more sewing machines,not including another 10 million sewing machines in schools of all kinds,need service at least once a year,and quite possibly four or more times each year.I know some women who return their sewing machines to repairmen time after time to get them fixed properly.I’ve seen sewing machines come out of repair shops in worse condition than they were when they went in.
So I’ve decided to write an introduction book to sewing-machine repair and teach people how to repair their own sewing machines at home.It’s not that difficult.In the book,I will teach you everything you need to know about how to repair your sewing machine.
【小题1】The author wrote the passage to .
A.teach women to repair their sewing machines. |
B.explain his or her purpose in writing the book |
C.introduce the reasons for doing one’s own sewing |
D.tell us that sewing-machine repair is a fast-growing business |
A.they cannot buy the clothes they see in magazines |
B.their husbands or boyfriends want them to do so |
C.ready-to-wear clothes cost a great deal of money |
D.they can’t get great satisfaction from buying clothes |

C.don’t easily get broken |
D.need service 4 times a month |
A.the book will also show you how to make nice clothes |
B.there are not enough sewing-machine-repair shops in America |
C.over 99 million sewing machines need service at least once a year |
D.the demand for excellent service of sewing machines grows the fastest in America |
The dream of flying like Buzz Lightyear never dies. For years, space-age inventors have tested one wearable jet pack after another. And time after time, the designs have been grounded by dangerous fuels, excessive weight, or very loud noise levels. Now a Canadian inventor has sidestepped those weaknesses with an aquatic jet pack. Designed for travel over lakes or oceans, it’s driven by pressurized water, not burning rocket fuel.
When Raymond Li first told the idea for the aquatic jet pack to his friends, they said he must be nuts. How could a jet pack carry that much water? Its thrust-to-weight rate would be so low and it would never become airborne. Thrust-to-weight rate is a measure of the forward force produced compared with the weight of the vehicle. A vehicle with a low thrust-to-weight rate is relatively heavy for the amount of force it generates.
Li's genius idea was to place the jet pack’s engine and its water pump in a separate boat. The pump would draw water from the lake the boat was floating on. It would then force the water under pressure through a hose connected to the jet pack. The hose would be long enough to let the pack go up as high as 8.5 meters (28 feet) in the air.
Today, Li's invention, the Jetlev-Flyer, is ready to go into production. The pack itself, complete with jet nozzles (管嘴) and handlebars, weighs just 14 kilograms. The boat is a floating pod. To take off, the operator hits a trigger on a handlebar, which starts the pump, and then turns the throttle. Two streams of high-velocity water shoot through the hose and out the nozzles, lifting the operator into the air. The operator hovers there or pushes down on the handlebars, zooming forward at speeds of up to 64 kilometers per hour, pulling the pod behind.
【小题1】All the following factors contribute to the failure of inventing a wearable jet pack EXCEPT ______.
A.excessive water | B.unbearable noise | C.unsafe fuels | D.too much weight |
A.improved | B.reduced | C.avoided | D.solved |
A.exciting | B.crazy | C.realistic | D.creative |
A.His friends encouraged him to do the invention. |
B.He put the engine and its water pump in the same boat. |
C.The success of his invention lies in his bravery. |
D.His invention finally succeeded and will go into production. |
a. The throttle is turned. b. The operator is lifted into the air.
c. A trigger is hit. d. Two streams of water shoot out.
The pump is started.

Some people are lucky enough to be born with a good sense of direction and even if they have only visited a place once, they will be able to find it again years later.
I am one of those unlucky people who have poor sense of direction and I may have visited a place time after time but I still get lost on my way there. When I was young I was so shy that I never dared ask complete strangers the way and so I used to wander round in circles and hope that by some chance I would get to the place I was heading for.
I am no longer too shy to ask people for direction, but I often receive replies that puzzle me. Often people do not like to admit(承认)that they didn’t know their hometown and will insist on telling you the way, even if they do not know it; others, who are anxious to prove that they know their hometown very well, will give you a long list of directions which you can not possibly hope to remember, and still others do not seem to be able to tell between their left and their right and you find in the end that you are going in the opposite(相反的)direction to that in which you should be going.
If anyone ever asks me the way to somewhere, I always tell them I am a stranger to the town in order to avoid giving them wrong direction but even this can have embarrassing results.
Once I was on my way to work when I was stopped by a man who asked me if I would direct him the way to the Sunlight Building. I gave my usual reply, but I had not walked on a few steps when I realized that he had asked for directions to my office building. However, at this point, I decide it was too late to turn back and search for him out of the crowd behind me as I was going to meet with someone at the office and I did not want to keep him waiting.
Imagine my embarrassment when my secretary showed in the very man who had asked for directions of my office and his astonishment when he recognized me as the person he had asked.
1.What is the writer going to do when someone asks him for direction?
A.He will direct the right way to the person willingly.
|
B.He will reply to it by the means of being a stranger to the town.
|
C.He will give the very person long list of direction.
|
D.He is going to show the man an opposite direction. |
2.Why did the writer consider himself to be an unlucky dog?
A.Because of his poor sense of direction. |
B.Because he always forget the way to home. |
C.Because he did not have any friend. |
D. Because he used to be shy and dared not ask others the way. |
3.How did the visitor feel when he was showed into the very room?
A.He felt strange. |
B.He felt embarrassed. |
C.He felt very sad. |
D.He felt astonished. |
4.Who showed the right way to the interviewee according to the passage?
A.Someone we don’t know. |
B.The writer did it for himself.
|
C.The secretary did so. |
D.A warm-hearted old lady did itI. |
