17．Our environment isn't as green and beautiful as it should be．There are steel（鋼鐵）monsters blocking out the sun，blowing out dangerous smoke，and letting out poisonous chemicals into rivers，cars producing harmful waste gas，people throwing out waste in a wrong way and all other kinds of sources that ruin the planet．Facing current environmental problems，people need to do their best to save the earth．
You can see many big garbage dustbins in the streets．They're not there for a show，but for you to drop your waste．We should realize that what we do does count．So next time you get that urge to throw gum or a chocolate package out of the car window，or"accidentally"drop as you walk down the street，ask yourself how much waste you've been contributing to the environment with that bad habit going on for years．
At home，the first thing we can do to protect the environment is avoid letting water run continuously and make sure that taps（水龍頭）are not leaky（漏的），which would help greatly in scrimping．Another is to use energy-saving lights，and turn them off before you leave the rooms．It is not only energy-saving，but also cuts down electricity costs．
Recycling is a method to make items reusable．Many things you want to throw out can be made into new products through the reproducing process．Use your imagination to come up with ways on things that you can use again．
Pass the message of simple ways to save the environment on to kids．Starting with kids is a good way of teaching the message early in their lives，in the hope that they can carry it forward as they grow older．
With environmental protection awareness in mind，we can do what we can，for the results are to have a big effect on the planet．As long as we do our part，the world is one small step closer to being saved．

分析 文章中主要向大家介紹了一些如何保護(hù)環(huán)境的方法．我們生活的地球本應(yīng)該更綠、更漂亮．但是，隨著廢水、廢氣的排放及亂扔垃圾，我們生活的環(huán)境出現(xiàn)了很多問(wèn)題．因此我們應(yīng)該盡力拯救地球．
解答 24．C 詞義猜測(cè)題，根據(jù) 第一段There are steel（鋼鐵）monsters blocking out the sun，blowing out dangerous smoke可知"steel monsters"指的是排放廢氣的大型工廠，故選C．
25．B 細(xì)節(jié)理解題，根據(jù)第五段"Pass the message of simple ways to save the environment on to kids．Starting with kids is a good way of teaching the message early in their lives，…"可知本段講述的是保護(hù)環(huán)境要從孩子開始，應(yīng)該把環(huán)保的意識(shí)和方法教給孩子們．故選B．
26．D 細(xì)節(jié)理解題，根據(jù)第二段的"We should realize that what a little we do does count．"和最后一段的"As long as we do our part，the world is one small step closer to being saved．"可知，不能小看點(diǎn)點(diǎn)滴滴的小事，A項(xiàng)正確；根據(jù)第四段"Many things you want to throw out can be made into new products through the reproducing process．"可知，許多廢棄的東西可以通過(guò)加工過(guò)程變成有用的東西，B正確；根據(jù)第三段最后一句"It's not only energy-saving，but also cuts down electricity costs．"可知，節(jié)約用電不僅環(huán)保，也能節(jié)約電費(fèi)，C正確；而D"不好的習(xí)慣會(huì)對(duì)環(huán)境有所貢獻(xiàn)"是不正確的表述．故選D．
27．C 推理判斷題，通讀全文可知文章分段講述了把垃圾扔進(jìn)垃圾桶；在家節(jié)約用電、用水；從教育孩子做起等方面來(lái)教大家如何保護(hù)環(huán)境．故選C．
點(diǎn)評(píng) 考查學(xué)生的細(xì)節(jié)理解和推理判斷能力．做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確選擇．在做推理判斷題時(shí)不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．
