8．Isn't it sad for us to see the large acres of rainforest being destroyed（毀滅） by humans？

分析 看到大片大片的雨林正被人類毀滅，這難道不悲哀嗎？

解答 destroyed．本題考查動(dòng)詞用法．根據(jù)所給的漢語提示"毀滅"和首字母可知，此處是動(dòng)詞destroy，根據(jù)此空前be動(dòng)詞以及句意可知，此處為被動(dòng)語態(tài)（be done），故填destroy的過去分詞destroyed．

點(diǎn)評 本題考查動(dòng)詞用法．學(xué)生需要掌握相關(guān)動(dòng)詞用法，根據(jù)首字母以及句意，判斷所填詞匯，根據(jù)句子結(jié)構(gòu)，對所填詞匯進(jìn)行變形，得出正確形式．

（36）B You can see or do something a million times，but you can only see or do it for the first time once．As a result，first time experiences usually leave a deep mark in our minds for the rest of our lives．So try to experience something different and you'll have more memories!

17．The National Gallery of Art in Washington，D．C．，is one of the world's greatest art museums．Millions of people have entered its doors to see paintings by the world's fine artists．But if these priceless masterpieces are to be preserved，the Gallery must protect them carefully．The Gallery's 135-man guard force has successfully prevented theft，but protecting the paintings from nature is a greater problem．
In past times，the owners of paintings did not protect them from damaging changes in humidity and temperature．As a result，the life of these paintings was shortened．In the National Gallery，however，humidity and temperature are carefully controlled．The building is air-conditioned in summer and heated in winter．The air-conditioning and heating systems are so important to the life of the paintings that the Gallery has two of each system．If one should fail，the extra one can take over．
Light is another enemy of paintings．Ultraviolet rays （紫外線） in light cause paintings to fade （褪色）．Long ago，paintings often hung in dark churches and palaces．A coat of varnish （清漆） was a protection from the weak light．But when museums took over the care of many paintings，they were often hung in brighter light than before．Soon they were in danger of fading．The damaging effects of light were increased when the museums removed the varnish coating，yellowed with age．
To protect its paintings，the National Gallery installed （安裝） a special kind of glass in its skylights．This glass allows visible lights to enter the building but it keeps out harmful ultraviolet rays．The Gallery has also developed new and better varnishes which help to keep paintings from fading．Thanks to these new precautions （預(yù)防措施），many of the world's greatest paintings are being well protected for future generations to enjoy．
32．The text mainly tells us aboutD．
A．the guard force in the National Gallery
B．the air-conditioning and heating systems in the National Gallery
C．priceless paintings of past times
D．protecting great paintings from nature
33．What does harm to paintings according to the text？A
A．Humidity，temperature and light．
B．Humidity，temperature and varnish．
C．Humidity，light and varnish．
D．Temperature，light and varnish．
34．Why did the museums remove varnish coatings from some paintings？C
A．They had built glass boxes for the paintings．
B．They had taken over the care of the paintings．
C．They found the coatings yellowed with age．
D．They would add other coating materials to the paintings．
35．We can infer from the text thatB．
A．the National Gallery has done little to protect the paintings
B．the care of the world's greatest paintings is both a big responsibility and a great challenge
C．you can touch these paintings while you are in the National Gallery
D．the guard force in the Gallery has not done a good job．
