Can you imagine printing food? Some scientists are trying to revolutionize the dining experience by doing this. They hope that having a 3D printer in the kitchen will become as commonplace as the microwave. Scientists say that they are easy to use: you simply have to select a recipe and put the raw food "inks" into the printer. You can also change the instructions to make the food exactly how you want it. This means that it would be very quick and easy to create tasty and nutritious meals.

They say that if people used 3D printers to create meals there would be less need for traditional growing, transporting and packaging processes as food production would be a lot easier. For example, alternative ingredients (原料) such as proteins from insects could be changed into tasty products. And as is known, those traditional activities are not beneficial to our surroundings.

This technology could also help people who suffer from dysphagia (a swallowing disorder). The patients could program the printer and softer versions would be made so that they would not have trouble swallowing them.

However, some people think that using 3D-printed foods would be a disaster. It could take away many jobs, including those for growing, transporting and packaging food. Imagine a world where there was no need for farming or growing crops and the same tastes could be printed from a raw "food ink". Likewise, traditional cafes and restaurants might lose business. Also, there are concerns about the nutritional value of printed food: is it really possible to get the nutrients we need from food-based inks?

What's more, cooking and eating together with family and friends has long been a traditional and enjoyable activity. It is hard to imagine a world where the pastime of cooking is dead and meals can be created at the touch of a button.

1.What do scientists think of 3D food printing?

A. It is cheap to use it.　　 B. It is environment-friendly.

C. It is advancing quickly.　　 D. It needs improving.

2.What does the underlined part in Paragraph 3 refer to?

A. The printed foods.　　 B. Their favorite foods.

C. The more nutritious foods.　　 D. The more tasty foods.

3.What can we infer about the printed foods from Paragraph 4?

A. Their raw "food inks" are more nutritional.

B. People would get more jobs produced by them.

C. People need more evidence about their nutrition.

D. They would be bought in traditional restaurants.

4.What is the best title for the text?

A. The growth of 3D food printing　　 B. The future of 3D food printing

C. The 3D food printing business　　 D. The two sides of 3D food printing

Imagine this: you get up in the morning and put on a custom printed T-shirt. Then you eat some 3-D printed food and relax on your printed sofa. Perhaps you take a ride in a printed electric car to the hospital to get a printed tooth fitted.

Though some of these things may seem impossible, they’re closer to reality than you might think. The world of 3-D printing is coming to a store near you soon.

The idea of 3-D printing is to produce complicated shapes in a very personalized way. If you want to make a totally new object, you need to make a virtual design in a CAD（computer aided design）file first. Or you can use a 3-D scanner to make a digital copy of an object. Then, based on the design or copy, the 3-D printer makes paper-thin slices out of liquid, plastic, or metal and puts them together to create the object you want.

There are many areas in which 3-D printing can change our lives. One such area is health care. Researchers have developed simple 3-D printed organs, which can be used in life-saving operations. A 17-year-old boy in the US has also recently developed a brain-powered, 3-D printed replacement hand. From heart monitors to fake limbs（四肢）, we can soon be living longer thanks to 3-D printed technology.

Another area that 3-D technology looks sure to change is food. Can you imagine being able to print your favorite dishes at home at the touch of a button? Even big companies are behind the trend. Hersheys, one of the largest chocolate makers in the world, recently announced that it would start producing chocolate with the help of 3-D printers. NASA, the US space agency, has reportedly spent $125,000 （767,594 yuan） developing a “3-D pizza printer”.

It is not yet clear how long it will take until 3-D printers are available to everyone. But one thing is for sure: the possibilities are endless.

1.The purpose of the first paragraph is to ________.

A. list some major 3-D printing breakthroughs

B. describe the characters of 3-D printing

C. picture a future life with 3-D printing

D. describe the benefits that 3-D printing has brought to our lives

2.Compared with traditional manufacturing procedures, 3-D printing ________.

A. isn’t practical in daily life

B. relies less heavily on the use of 3-D scanners

C. can produce complicated products in larger sizes or numbers

D. has an advantage in meeting the personal needs

3.We can infer from the article that ________.

A. there is still a long way to go before everyone can have access to 3-D printing

B. 3-D printed organs and limbs are as effective as real ones

C. big food companies are major players in the 3-D printing industry

D. people can create any object with any material by 3-D printing

4.What can be the best title for the text?

A. What is 3-D printing?

B. A new technology-3-D printing.

C. How to use 3-D printing?

D. The development of 3-D printing.

高三英语阅读理解中等难度题查看答案及解析

What should you think about when trying to find your career? You are probably better at some school subjects than others. These may show strengths that you can use in your work. A boy who is good at mathematics can use that in an engineering career. A girl who spells well and likes English may be good at office work. So it is important to know the subjects you do well in at school. On the other hand, you may not have any specially strong subjects but your records show a general satisfactory standard. Although not all subjects can be used directly in a job, they may have indirect value. A knowledge of history is not required for most jobs but if history is one of your good subjects you will have learned to remember facts and details. This is an ability that can be useful in many jobs.

Your school may have taught you skills, such as typing or technical drawing, which you can use in your work. You may be good at metalwork or cookery and look for a job where you can improve these skills. If you have had a part-time job on Saturdays or in the summer, think what you gained from it. If nothing else, you may have learned how to get to work on time, to follow instructions and to get on with older workers. You may have learned to give correct change in a shop, for example. Just as important, you may become interested in a particular industry or career you see from the inside in a part-time job.

Facing your weak points is also part of knowing yourself. You may be all thumbs when you handle tools; perhaps you are a poor speller or cannot add up a column of figures. It is better to face any weakness than to pretend they do not exist. Your school record, for instance, may not be too good, yet it is an important part of your background. You should not be apologetic(认错的) about it but instead recognize that you will have a chance of a fresh start at work.

1.What is the passage mainly about?

2.The writer thinks that a student to have a part-time job is probably ___.

3.From the passage we learn that if a student’s school performance is not good, he ___________.

4.From the last paragraph we know one should _________.
