Question

【題目】根據(jù)短文內(nèi)容及首字母提示，填寫所缺單詞，使短文意思完整。每空限填一詞。

How do we know the time? A clock, a watch or a cell 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 w【1】of telling the time.

About 5,500 years ago, the Egyptians i【2】the sun clock. This was a tall stone structure. Its shadow (影子)showed the movement of the s【3】they were able to determine（測定）midday.

About 3,500 years ago,the Egyptians made a sundial. It was smaller than the sun clock and could measure (測量)the time for half a day. On c【4】days or at night it was impossible to tell the time with a sun clock or a sundial.

Water clocks were the f【5】clocks not to use the sun. The idea is simple. Water flows（流動） from one container（容器）to another. When the water reaches a certain l 【6】 it moves a lever (控制桿)and this 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 f【7】

o keep accurate（精確的）time.

In the 13th century. the mechanical clock was invented. This was more accurate, b【8】was expensive to make. Over the next few centuries it was developed. For example, springs(發(fā)條)were added around 1500. This i【9】accuracy and allowed clocks to be smaller.

In 1927, the first quartz clock was developed. Clocks became cheaper to build and own. People began depending on them more and more to run businesses, markets and so on.

More recently, in1956, came the digital clock. And nowadays satellites（人造衛(wèi)星）send our cell phones the time to the exact second. There has been a lot of progress in timekeeping but some things never c【10】. Man of us still have trouble getting out of bed on time and not missing appointments.

【解析】本文主要說明了是計時工具的發(fā)展歷史，從原始計時到機(jī)械計時再到數(shù)碼計時。

【1】 前文提到”A clock, a watch or a cell phone”, 可知這里是在說計量時間的“方法、手段”， 又因為前有形容詞 different 修飾，可知不止一種，所以要填復(fù)數(shù) ways。

【2】根據(jù)前文 people have developed 可知，本文是寫古人發(fā)明的計時方法， 所以這里填 invent“發(fā)明”；根據(jù)時間狀語“about 5500 years ago”可知要使用一般過去時，所以填 invented.

【3】根據(jù)文章可知埃及人發(fā)明的 the sun clock 是計時工具，那它的影子記錄的肯定是太陽的運(yùn)動，這里填 sun。

【4】根據(jù)文章可知，埃及人發(fā)明的 sundial 和 the sun clock 都是通過記錄太陽的運(yùn)動軌跡來計時的，所以在沒有太陽的陰天和晚上就用不了了，所以應(yīng)該填cloudy.

【5】前面兩段說的計時工具都是基于太陽的運(yùn)動，缺點是沒有太陽的日子和時間里就用不了。所以根據(jù)文章發(fā)展，這里寫到了 water clocks 是第一種不用太陽而用水來計時的，所以應(yīng)該是“首次”，填 first.

【6】根據(jù)前文，water clock 的工作原理是水從一個容器流到另一個容器，所以隨著時間推移，水位應(yīng)該是不斷上升的，所以填 level，表示當(dāng)水到達(dá)一個特定的水位時。

【7】根據(jù)這幾段的行文邏輯，每次介紹一個計時工具都是先說優(yōu)點再說缺點， water clock 的優(yōu)點是沒有太陽也能用，所以在中東和中國很受歡迎。根據(jù)轉(zhuǎn)折詞 but 可知后面該寫缺點了，根據(jù)下一段“機(jī)械鐘更加準(zhǔn)確”可知水鐘的缺點應(yīng)該是不太準(zhǔn)確。所以應(yīng)該是考 fail to do 不能做什么。又因為全文都是一般過去時，所以填 failed.

【8】機(jī)械鐘的優(yōu)點是更加準(zhǔn)確，空后面的分句說的是造價高，所以是寫缺點，前后出現(xiàn)了語義轉(zhuǎn)折，所以應(yīng)該填 but.

【9】根據(jù)前文“接下來的幾個世紀(jì)，它被改良了”，所以應(yīng)該是“提升”了精確性，所以填 improved.

【10】根據(jù)前一句“在計時上已經(jīng)有了很多的進(jìn)步，但是”可知后面應(yīng)該出現(xiàn)語義轉(zhuǎn)折，一些東西變了那另一些東西肯定是從來沒“改變”，而且通過 nowadays 可知最后一段的時間已轉(zhuǎn)到了現(xiàn)在，所以應(yīng)該用一般現(xiàn)在時，填 change。
