【題目】閱讀與表達(問答式)

On 19th September 1783, Pilatre De Rozier, a scientist, sent the first hot air balloon. The passengers were three animals and the balloon stayed in the air for about 15 minutes before hitting back to the ground.

The first manned(載人的) flight was about 2 months later, with a balloon made by 2 French brothers. The balloon flew for a period of 20 minutes.

Sailing through the sky in the balloon, high above buildings and trees, you can't feel or hear the wind because you're traveling in the same direction and at the same speed as it is.

A hot air balloon has three main parts: the balloon, called an envelope; a basket, where passengers ride; and a burner system, which supplies the hot air.

Most balloon envelopes are made of strong, lightweight nylon(尼龍). They are different in size and shape, but they have to be really, really big to lift even one person. Most weigh more than an adult man.

The basket is usually made of wicker(柳條), which is strong but not too hard. It needs to bend a bit for a soft landing, just like a good jumper bends her legs instead of keeping them straight when she lands.

The hot air balloon works on the theory that hot air rises faster than cooler air. When the burner system is turned on, it makes a noisy sound, but once the balloon is flying, the burner can be turned off. The air in the envelope will then cool, and the balloon will slowly go down unless the pilot starts the burner system again.

To control a hot air balloon, a pilot adds hot air to it to go up or lets the air out to go down until he finds a wind blowing in the direction he wants to fly. But no matter which way the wind blows, the passengers have an amazing bird's-eye view of the world.

根據(jù)短文內容，完成下列小題。

【1】Who were the passengers on the first hot air balloon?

【2】Did the first manned balloon fly for 20 minutes?

【3】Why is the basket usually made of wicker?

【4】How does a pilot control the hot air balloon?

【5】What are the main points in this passage?

【題目】

Artificial intelligence(AI in short人工智能) can give computers and machines ability(能力) to think and work like humans. AI scientists and engineers have made much progress in this field.

Facial Recognition

AI is rapidly catching up with the human ability to read faces. Facial recognition(識別) is used widely in the world. Chinese police use this technology to identify(認出) criminals(罪犯). They had caught about 50 criminals at Zhang Xueyou's concerts by October, 2018. It also checks the ID of ride-hailing(網(wǎng)約車) drivers and lets people pay for things with a smile.

Self-driving Cars

Most drivers may wave or nod at passers-by(路人，行人) to let them cross the street, but self-driving cars don’t have this ability. Car makers are testing(測試) a light signal system(燈管信號系 統(tǒng)) to help them “speak” to humans. For example, if a driverless(無人駕駛) car is yielding(讓路), it will flash two white lights side to side. A rapidly flashing light tells passers-by that the car is about to speed up(加速).

Service Robots

Imagine this—you come back home from school, and your robot housekeeper is waiting for you at the door. After dinner, he teaches you to play the piano, just like a real music teacher. Such thoughts will soon happen in the real world. In the future, more and more service robots will become good home helpers.

AI is so powerful that it can help human beings and even replace us in many jobs.

【1】According to the passage, what is facial recognition used for?

A.Driving cars.B.Making people smile.

C.Calling the police.D.Checking people’s information.

【2】Which technology has been used in real life according to the passage?

A.Service Robots at school.B.Robots as ride-hailing drivers.

C.Facial recognition for payment.D.Light signals for self-driving cars.

【3】 play(s) an important role in catching criminals.

A.Zhang XueyouB.Service robots

C.Self-driving car makersD.Artificial intelligence

【4】What can we learn from the passage?

A.People use AI in many different ways.

B.AI will take the place of(代替) human beings in all jobs.

C.Self-driving cars will be able to talk like humans.

D.Criminals were caught for inventing facial recognition.

【題目】

When I was eight years old, my mother told me to put my coat on because we were going to go somewhere_______. Usually, that meant we were going to see someone important. I would at least get a new toy. I asked which one it would be that day, and she told me that I would get something _________than a toy. She said I would get “access（通道）to a world of toys.”I had no real idea what she meant. Did that mean we were buying a toy _______?

But we did not end up at any toy store. Neither did we finally see anyone we knew.

_______, mother pulled her car into a parking lot in front of a building that looked like something out of the past. It didn’t have a modern_________at all.

We took stone steps up to the entrance. Only then I found out what this place was, because there was a sign that _______“Marcy Public Library”. We pushed the door open, and my mother led me to the front desk. “I’d like to get my daughter a library card”, she told the man_________the desk. He asked her to fill out a form. “What kind of books do you like to read?” he asked. I was too shy to _________. I only smiled. “Well, you’ll find it out in time,” he said. I do not remember_________I picked out that day, but I know that in the years that followed I read through books on history, books of poetry, and books about art.
