Question

【題目】 How do we know the time? A clock, a watch or a mobile phone can help us. However, many years ago there were no clocks and knowing the time was not so easy. Over the centuries people have developed different ways of telling the time.

About 5, 500 years ago, the Egyptians invented the sun clock. This was a tall stone building. Its shadow(影子) showed the movement of the sun. So people were able to know midday. The Egyptians made a sundial about 3, 500 years ago. It was smaller than the sun clock and could let people know the time for half a day. On cloudy days or at night it was impossible to tell the time with a sun clock or a sundial. Water clocks were the first clocks not to use the sun. The idea is simple. Water flows(流動) from one bottle to another. When the water reaches a certain level, it shows the hours. The Egyptians used water clocks about 3, 400 years ago. These clocks were popular in the Middle East and China. But they failed to make people know the exact time.

In the 13th century, the mechanical clock was invented. This was more exact, but it was expensive to make one. Over the next few centuries it was developed. For example, springs(發(fā)條) were added around 1500. This enabled people to get the correct time and allowed clocks to be smaller. In 1927, the first quartz clock was developed. Clocks became cheaper to build. It’s also cheaper for ordinary people to own a clock. People began depending on them more and more to run business, markets and so on. More recently, in 1956, came the digital clock. And nowadays satelites send our mobile phones the time to the exact second.

There has been a lot of progress in timekeeping. Clocks are always changing but some things never change. Many of us still have trouble getting out of bed on time and not being late for school or work.

Answer 1

【答案】

【1】B

【2】D

【3】C

【4】A

【5】B

【解析】

本文是一篇說明文，介紹了從古至今計時方法的不斷演變和進步。

【1】

題意：根據本文內容，下雨天我們不能用________來判斷時間。

細節(jié)理解題。根據原文“On cloudy days or at night it was impossible to tell the time with a sun clock or a sundial”可知，太陽鐘是用來顯示太陽運動軌跡從而判斷時間的，所以雨天的時候不能使用。B選項sun clock“太陽鐘”符合題意，故選B。

【2】

題意：第3段中畫線單詞“ordinary”的意思是？

詞句猜測題。根據原文“In 1927, the first quartz clock was developed. Clocks became cheaper to build. It’s also cheaper for ordinary people to own a clock”可知，石英鐘問世之后，時鐘的成本開始變便宜，許多普通人也買得起時鐘了。畫線單詞“ordinary”意為“普通的”，故選D。

【3】

題意：文中提到了多少種時鐘？

細節(jié)理解題。通讀全文可知，一共提到了sun clock、sundial、water clock、mechanical clock、quartz clock、digital clock六種時鐘。C選項Six“6種”符合題意，故選C。

【4】

題意：以下哪一項展示了本文的篇章結構？

篇章結構題。第一段用于引出時鐘演變的歷史這一話題，第二、三段則是具體描述了不同歷史時期出現的時鐘及其優(yōu)缺點，第四段是文章結尾，對時鐘演變歷史進行了評價，即時鐘在計時方面的進步隨著科學技術的進步而不斷進步。由此可知本文采用“總-分-總”的篇章結構，即“①—②③—④”，故選A。

【5】

題意：這篇文章主要講什么？

主旨大意題。通讀全文可知，本文是一篇說明文，介紹了從古至今計時方法的不斷演變和進步。B選項The development of timekeeping“計時技術的發(fā)展”符合題意，故選B。
