________ from endless homework on weekends, the students now find their own activities, such as taking a ride together to watch the sunrise.

A．Freed            B．Freeing           C．To free            D．Having freed

 

【答案】

A

【解析】

試題分析：考查分詞做狀語(yǔ)。本題的動(dòng)詞free擺脫…；使…免受…；與后面主語(yǔ)the students構(gòu)成被動(dòng)的關(guān)系，故使用過(guò)去分詞在句中做狀語(yǔ)。句意：在周末擺脫了無(wú)休止的家庭作業(yè)，學(xué)生們現(xiàn)在有了他們自己的活動(dòng)，例如一起騎自行車(chē)去看日出。故A正確。

考點(diǎn)：考查分詞做狀語(yǔ)

點(diǎn)評(píng)：當(dāng)分詞做狀語(yǔ)的時(shí)候，如果構(gòu)成分詞的動(dòng)詞與句子的主語(yǔ)構(gòu)成主動(dòng)關(guān)系，就使用現(xiàn)在分詞做狀語(yǔ)；當(dāng)二者構(gòu)成被動(dòng)關(guān)系，使用過(guò)去分詞做狀語(yǔ)。如果分詞的動(dòng)作發(fā)生在謂語(yǔ)動(dòng)詞之前，就使用分詞的完成式。如果分詞與句子的主語(yǔ)沒(méi)有關(guān)系，可以使用狀語(yǔ)從句或者獨(dú)立主格結(jié)構(gòu)。

科目：高中英語(yǔ) 來(lái)源： 題型：閱讀理解

We learned that fossil fuels were formed before and during the time of the dinosaurs（恐龍）. We are using up the fuels. We can save fossil fuels by protecting and finding ways to use energy from “endless sources”, like the sun and the wind. Some people suggest that we should start using hydrogen（氫）.

Hydrogen is a colorless, smell-less gas that takes up 75 percent of the whole universe. Hydrogen is found on earth only in mixture with other elements such as oxygen, carbon and nitrogen. To use hydrogen, we must separate it from these other elements.

Hydrogen can be used in NASA’s space program as fuel for the spaceships, and in fuel cells that provide heat, electricity and drinking water for astronauts. Fuel cells are devices that directly change hydrogen into electricity. In the future, hydrogen could be used to fuel vehicles and aircraft and provide power for our homes and offices.

Hydrogen can be made from natural gas. An electrical current can also be used to separate water into its elements of oxygen and hydrogen. Some plants in the sea and bacteria（細(xì)菌） give off hydrogen through sunlight under certain conditions.

Hydrogen as a fuel is high in energy. Yet a machine that burns pure hydrogen produces almost zero pollution. NASA has used liquid hydrogen since the 1970s to drive rockets and spacecraft into orbit. Hydrogen fuel cells power the spacecraft’s electrical systems, producing clean by-product-pure water, which the crew drinks.

56. We can get hydrogen from the following EXCEPT ______ according to the passage.

A. natural gas    B. water                     C. creature in the sea          D. bacteria

57. Why could the hydrogen be used widely in the future?

A. Because it is of high quality.               

B. Because it has no pollution. 

C. Because it is easy to get it from all kinds of ways.      

D. Because there are much hydrogen existing in the universe.

58. The passage mainly tells us ________.

A. the usage of a new energy source        B. the future energy sources

C. a new energy source －h(huán)ydrogen        D. how to get the energy source
