Question

【題目】

A solar-powered airplane finished its first international flight from Switzerland to Belgium. This is a big step for solar power. Solar energy is clean and useful and you can find it everywhere. But what is solar energy? How do we use it? Let’s find out.

Have you ever seen houses with shiny boards on the roofs? Those families are using solar power.

Solar power converts (轉換) the sun’s energy which is said to be greater than the other energy used by all humans all the year. People can convert solar power into heat and electricity.

In the 1830s, British scientist John Herschel used a solar collector to cook food in Africa. This is said to be human’s first try at using solar energy. Today, people use it for many things.

Solar energy can light streets, warm houses and heat water. Unlike other resources, the sun’s energy will run out for billions of years.

Australian students from the University of New South Wales made a solar-powered car on their own. It reached a speed of 120 km per hour. The car uses the same amount of electricity as an oven (微波爐). Moreover, American scientists made a solar-powered nanosatellite (微型衛(wèi)星). Scientists sent it into space in 2012 to try to find Earth-like planets.

However, solar power has its problems. The amount of sunlight that reaches the Earth’s surface changes because of time and weather.

根據上面短文內容填空。

【1】It is _________ for a solar power when _________ flew from Switzerland to Belgium.

【2】Solar power can be converted into _________ and it is _________ among all the energy people use all the year.

【3】John Herschel, a scientist from _________ cooked food with a solar collector in Africa. And this is the first time for humans to _________.

【4】Although solar energy can do many things for humans such as lighting streets, _________, people will _________ it billions of years later.

【5】Australian students made a solar-powered car by _________ while American scientists made a nanosatellite which _________ into space in 2012.

【1】 a big step a solar-powered airplane

【2】 heat and electricity the greatest

【3】 British try at using solar energy

【4】 warm houses and heat water run out of

【5】 themselves was sent

【解析】

本文介紹了太陽能的作用以及人類利用太陽能的一些實例。

【1】

句意：當一架太陽能飛機從瑞士飛到比利時時，這對于太陽能來說是邁出了一大步。

根據A solar-powered airplane finished its first international flight from Switzerland to Belgium. This is a big step for solar power，可知，一架太陽能飛機完成了它首次從瑞士到比利時的國際旅行，這對于太陽能來說是邁出了一大步，所以第一個空格填a big step，第二空格填a solar-powered airplane。故答案為a big step，a solar-powered airplane。

【2】

句意：太陽能可以被轉化成電能和熱能，它是人們全年使用的最大能量。

根據People can convert solar power into heat and electricity，可知，太陽能可以被轉化成熱能和電能，所以第一個空格處填heat and electricity。根據Solar power converts (轉換) the sun’s energy which is said to be greater than the other energy used by all humans all the year，可知，它是人類全年使用的最大能量，三者以上的比較用最高級，所以第二個空格填the greatest。故答案為heat and electricity, the greatest。

【3】

句意：約翰·赫歇爾，一位來自英國的科學家在非洲用太陽能集熱器做飯。這對于人類是第一次嘗試使用太陽能。

根據In the 1830s, British scientist John Herschel used a solar collector to cook food in Africa. This is said to be human’s first try at using solar energy，可知，英國科學家約翰·赫歇爾在非洲用太陽能集熱器做飯。據說是人類第一次嘗試使用太陽能，所以第一個空格填British，第二個空格填try at using solar energy。故答案為British，try at using solar energy。

【4】

句意：盡管太陽能可以為人類做許多像照亮街道，溫暖房屋和加熱水這樣的事情，但是人類會在數億年后耗盡它。

根據Solar energy can light streets, warm houses and heat water，可知，太陽能可以照亮街道，溫暖房屋和加熱水，所以第一個空格填warm houses and heat water。根據Unlike other resources, the sun’s energy will run out for billions of years，可知，數億年后人類將耗盡它，run out和run out of都表示“耗盡”，run out是不及物動詞短語，run out of是及物動詞短語，空格后接賓語it，所以第二個空格填run out of。故答案為warm houses and heat water，run out of。

【5】

句意：澳大利亞學生自己做了一輛太陽能汽車，而美國科學家做了一個在2020年被發(fā)射到太空的微型衛(wèi)星。

根據Australian students from the University of New South Wales made a solar-powered car on their own，可知，來自新南威爾士大學的澳大利亞學生自己做了一輛太陽能汽車，固定搭配：by oneself表示“獨自”，反身代詞要與句中的主語在人稱單復數上保持一致，students是復數，所以第一個空格填themselves。根據Moreover, American scientists made a solar-powered nanosatellite (微型衛(wèi)星). Scientists sent it into space in 2012 to try to find Earth-like planets，可知，美國科學家做了一個太陽能微型衛(wèi)星，并在2012年發(fā)送至太空，此空格所在句子是一個定語從句，先行詞是單數名詞nanosatellite，在賓語從句中作主語，并且與謂語動詞send是被動關系，原句中sent是一般過去時，所以此空應填一般過去時的被動語態(tài)，故第二個空填was sent。故答案為themselves, was sent。
