阅读理解

What time is it?There are many ways you can find out the time. You may have a watch on your wrist (手腕). You can look at a clock on the wall. You can listen to the radio, watch TV or ring a number on the telephone to get the time.

It has not always been easy to know the time. A long time ago people looked at the sun to tell the time. They could tell the time of the day by looking at the sun in the sky: morning, noon or afternoon.

Around the year 1400, people began to use the hourglass (沙漏). It was made of glass with some sand in it. It was wide at both ends, but narrow in the middle. The sand ran from one end to the other in one hour. At the end of every hour, People turned the glass over and began again. Hundreds of years later a machine called clock was invented.

After that people made small clocks, so that they could carry them in their pockets. Then during World War I, men started wearing their watches on their wrists. It was easier to tell the time. Now almost everyone wears a wrist watch.

(1)、Which of the following is not mentioned to get the time?
A、A clock. B、The radio. C、A watch. D、A computer.
(2)、How could people tell the time of day before the year 1400?

 阅读下面短文,在空白处填入一个适当的单词或括号内单词的正确形式(每空不多于两个词)。

Have you heard of the app (应用程序) Douyin? It's quite popular nowadays. There are plenty {#blank#}1{#/blank#} funny short videos on it. We can learn {#blank#}2{#/blank#} to draw pictures do housework and so on from the videos. So I enjoy watching {#blank#}3{#/blank#} (they). But there are some {#blank#}4{#/blank#} (disadvantage) about the app. 

First, it can take {#blank#}5{#/blank#}too much of our time. We can easily become addicted (上瘾的) to it. Once, I enjoyed videos for {#blank#}6{#/blank#}(near) a whole afternoon. I forgot {#blank#}7{#/blank#} (do) my homework. It {#blank#}8{#/blank#} (steal) my time and energy. 

{#blank#}9{#/blank#} (two), there are lots of meaningless (无意义的) videos. For example, some people did boring things {#blank#}10{#/blank#}posted what they did on the app. Watching these videos is not {#blank#}11{#/blank#} (help) for the growth of the students. 

In a word, not everything on Douyin {#blank#}12{#/blank#} (be)good. So we shouldn't lose {#blank#}13{#/blank#} (we) in short videos for fun. We can set up {#blank#}14{#/blank#} time to go online, such as after homework. I think spending {#blank#}15{#/blank#} (little) than 20 minutes online each time is OK. What do you think?

 阅读下列短文,从每题所给的A、B、C和D四个选项中选出最佳选项。

If you've ever used pi in math class, you probably used the number 3.14. In fact, the number for pi is much longer. Pi is called an irrational number (无理数) because the digits (数位) after the decimal point (小数点) never end or repeat.

In 2015, a young man from India named Rajveer Meena set a world record by memorizing 70,000 digits of pi. But pi is much longer than that.

On Pi Day ( March 14th) this year, a company called Solidigm said it calculated (计算) pi to105 trillion (万亿) digits. And the 105 trillionth digit is 6. It broke the record for how many digits of pi we know.

Pi is really useful for circles in math. It helps us connect the circumference with the diameter of a circle.

Even NASA scientists use pi for their work of studying space. But they only need about 15 digits of pi for their calculations.

Calculating pi also has another important use. It's how scientists test new computer programs and data storage systems (数据存储系统).

Solidigm's calculation of pi took around 75 days to finish. The company's owner Brian Beeler said that the achievement needed a lot of work. They had to plan the calculation very carefully.

This isn't the first time that Solidigm has calculated pi. In 2022, Google Cloud calculated 100 trillion digits of pi. Solidigm matched that in 2023.

In the future, we'll keep finding more and more digits of pi. We'll never be able to calculate all the digits of pi because it goes on forever. But it still helps us see how great computers can be.
