高三英语单项填空中等难度题查看答案及解析

I needed to buy a digital camera, one that was simply good at taking good snaps (快照), maybe occasionally for magazines. Being the cautious type, I fancied a reliable brand. So I went on the net, spent 15 minutes reading product reviews on good websites, wrote down the names of three top recommendations and headed for my nearest big friendly camera store. There in the cupboard was one of the cameras on my list. And it was on special offer. Oh joy. I pointed at it and asked an assistant, “Can I have one of those?” He looked perturbed (不安).“Do you want to try it first?" he said. It didn't quite sound like a question. "Do I need to?" I replied. "There's nothing wrong with it?" This made him look a bit insulted and I started to feel bad. "No, no. But you should try it," he said encouragingly." Compare it with the others. "

I looked across at the others: shelves of similar cameras placed along the wall, offering a wide range of slightly different prices and discounts, with each company selling a range of models based around the same basic box. With so many models to choose from, it seemed that I would have to spend hours weighing X against Y, always trying to take Z and possibly H into account at the same time. But when I had finished, I would still have only the same two certainties that I had entered the store with: first, soon after I carried my new camera out of the shop, it would be worth half what I paid for it; and second, my wonderful camera would very quickly be replaced by a new model.

But something in the human soul whispers that you can beat these traps by making the right choice, the clever choice, the wise choice. In the end, I agreed to try the model I had chosen. The assistant seemed a sincere man. So I let him take out my chosen camera from the cupboard, show how it took excellent pictures of my fellow shoppers... and when he started to introduce the special features, I interrupted to ask whether I needed to buy a carry-case and a memory card as well.

Why do we think that new options (选择) still offer us anything new? Perhaps it is because they offer an opportunity to avoid facing the fact that our real choices in this culture are far more limited than we would like to imagine.

1. The shop assistant insisted that the writer should __ .

A. try the camera to see if there was anything wrong with it

B. compare the camera he had chosen with the others

C. get more information about different companies

D. trust him and stop asking questions

2. What does the writer mean by "it would be worth half what I paid for it"  (Paragraph 2) ?

A. He should get a 50% discount.

B. The price of the camera was unreasonably high.

C. The quality of the camera was not good.

D. The camera would soon fall in value.

3. The writer decided to try the model he had chosen because he __ .

A. knew very little about it

B. didn't trust the shop assistant

C. wanted to make sure the one he chose would be the best

D. had a special interest in taking pictures of his fellow shoppers

4. It can be inferred from the passage that in the writer's opinion, __

A. people waste too much money on cameras

B. cameras have become an important part of our daily life

C. we don't actually need so many choices when buying a product

D. famous companies care more about profit than quality

高三英语单项填空中等难度题查看答案及解析

Film cameras and digital cameras work in a similar way.

Film cameras

After all, a film camera is basically a light – proof (不透光的) box. It has a lens (镜头) system to focus light onto the film at the back of the camera.

Let’s suppose that we are outside on a beautiful summer day trying to take a picture of the family dog. We are using a film camera. We finally get the dog to lie still. You point the camera at him. What happens? Light goes into the camera lens and hits the shutter. In other words, nothing happens yet. Now let’s say that the dog looks really cute and you decide to snap a picture. What happens? When you press the button, the shutter opens for a very short period of time. A small amount of light passes through and hits the film at the back of the camera. This creates an upside-down and reversed (反向的)image on the film.

When you finish the roll of the film, you can take it to the photo shop to develop it and you will have a great picture of your dog!

Cameras come with different lens lengths. Why does it matter? Many small cameras have shorter focal lengths, which means that there is a small distance between the lens and the place where the light focuses at the back of the camera. This gives you a large view of the area you are taking a picture of. Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger. They are often called telephoto lenses. A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them.

Digital cameras

In digital cameras, the light falls not on film but onto a sensor (传感器) called a CCD (Charge Coupled Device). This digitally converts(转变) light and color into a digital information or pixels (象素). The CCD is the heart of any digital camera and usually the most expensive part ---- depending on how good it is.

1.Which of the following statements is TRUE?

A．Both digital and film cameras focus light onto the film.

B．All cameras have a sensor.

C．Digital cameras and film cameras have something in common. .

D．Small cameras usually have longer focal lengths.

2.In the “Film cameras” part, you fail to take the picture of the dog because _____.

A．light goes into the camera lens and hits the shutter

B．you haven’t aimed the camera at the dog

C．the image of the dog is not created

D．the sensor fails to convert light and color into a digital information

3.The main reason that sports photographers can get clear and big photos of players is that _ ___.

A．they use digital cameras        B．the lens of their cameras is excellent

C．their focus lenses are short    D．their focus lenses are long

4.Generally speaking, a digital camera’s price is ____.

A．closely related to the quality of the CCD

B．irrelevant to the quality of the CCD

C．closely related to the lens

D．irrelevant to the lens

One of the newest “smart” devices is an old favorite, a camera. And smart cameras are getting smarter all the time. Some are now built with machine learning tools to help them think for themselves. Machine learning involves patting large amount of data into a computer for processing.

Google Clips

One of the latest to launch is Google Clips. It is the first camera developed by the web search giant that is not built into a phone.

The small and light device is designed to be put somewhere in a room to take pictures by itself. It can also be stuck to an object or a person’s clothing.

Google says machine learning helps the camera choose the best times and situations for taking pictures and video clips. It can also recognize the faces of people or pets chosen by the user and take pictures of them in a more natural way.

The device is not yet being sold, but interested buyers can join a waiting list to be informed when it is available.

GoPro Hero

GoPro is another company developing machine learning technology. GoPro also uses machine learning to power its QuikStories feature. This tool takes existing photos and videos and automatically creates a finished video piece, complete with music and effects.

Snap Spectacles

Messaging app Snapchat sells a pair of sunglasses with a built-in camera that can record short video clips with the push of a button. Snap Inc. says the product, called Spectacles, is designed to “capture the moment, without taking you out of it.” Many smart phones already have facial recognition technology built into the devices.

Snap Inc. has started selling its Spectacles sunglasses online in the United States.

Apple iPhone X

Apple’s new iPhone X is being launched with its new Face ID system that it says will unlock the phone just by having the user look at it. This replaces the Touch ID on previous devices that used a fingerprint to unlock the phone.

Apple says the system works by projecting more than 30,000 dots on the face to create a kind of map. Apple claims its facial recognition is even secure enough to allow payments through its Apple Pay service.

1.What can machine learning tools help cameras do?

A.Get much smarter. B.Process more roughly.

C.Keep data for ever. D.Store more natural photos.

2.What can we know about Google Clips?

C.It can be built into a phone,

D.You can take photos automatically with it.

3.What is the special function of GoPro Hero?

B.It can record videos vividly.

C.It provides music and effects for videos.

D.It uses technology of machine learning.

4.Which of the following can now be bought surely on the Internet?
