　　Ⅴ.閱讀理解

　　Bedazzling (眼花繚亂) with their bright colors and eye-catching displays，fireworks light up our night skies during the holidays.However，these crowd-pleasers can have some damaging side effects.

　　Once a firework is set off，it only takes a couple of seconds before smoke，dust and harmful chemicals are let out into the atmosphere.The loud booming noises are caused by gunpowder.While the sounds may excite some people，they can be frightening to domestic and wild animals—as well as some humans.

　　The pretty colors you see are a result of more chemicals.Barium，added to make green，is known for its poisonous and radioactive qualities.Blue comes from copper compounds.Cadmium，lithium and lead—all found in fireworks—have been linked to diseases，such as allergies and skin rashes in both humans and animals.Acid rain has been linked to gases given off by fireworks，which sometimes go beyond the toxin (毒素) limits of the United States Clean Air Act.

　　Once all those chemicals come back down to the ground，they can cause problems too.Debris (碎片) from the fireworks falls to the ground，where animals can burn their paws or noses on piping hot pieces.Humans also are at risk of stepping on or picking up something sharp or hot.Meanwhile，debris that finds its way into waterways can damage animal habitats and water supply sources.

　　Instead of setting off fireworks，try to come up with some new ways for fun.Here are some ideas to get you started：

　　 Sky lanterns—a tradition that originated long ago in the most-populated Asian country.

　　 Party crackers—a favorite in the United Kingdom—give you noise and surprises without the mess of fireworks.You can make your own or buy eco-friendly crackers.

　　Want noise excitement with less volume？Consider a fireworks sound recording beforehand or break out the party horns (號角) and blow up a storm!

　　31．The advantages of fireworks can be seen below EXCEPT that________.

　　A．the special sounds of fireworks excite people

　　B．debris from fireworks can even find its way into water

　　C．the pretty and bright colors add to the beauty of night skies

　　D．fireworks are enjoyed as one of the crowd－pleasers

　　32．Which of the following is NOT true according to the passage?

　　A．Copper compounds are needed to make green in fireworks.

　　B．Chemicals in fireworks are both poisonous and dangerous.

　　C．Too much gases from fireworks can result in acid rain.

　　D．Chemicals in fireworks are harmful in the air and on the ground.

　　33．All the italicized (斜體的) words are probably________.

　　A．mineral materials

　　B．tiny solids

　　C．chemical elements

　　D．broken pieces

　　34．What is implied from the passage?

　　A．Gunpowder in fireworks makes loud booming noises.

　　B．It must be Indians who first started to hang sky lanterns.

　　C．Fireworks does less harm in the air than on the ground.

　　D．Fireworks can even break the balance of nature.

　　35．What can be concluded as the writer’s attitude towards fireworks?

　　A．It is not allowed to set off fireworks except during the holidays.

　　B．Fireworks should be banned and replaced by some other means.

　　C．Night is the best time to set off fireworks and see the pretty colors.

　　D．You cannot set off fireworks unless you come up with new ways.

　　6．B　7.A　8.C　9.A　10.D

　　Ⅲ.單項(xiàng)填空

　　11．D　本題考查近義詞辨析。第二個(gè)說話者的意思為“我們隊(duì)有較好的運(yùn)動員，因此我料想我們隊(duì)會贏”。此處是根據(jù)我們隊(duì)的實(shí)力進(jìn)行猜測。空格后面是從句，因此排除A，而B不符合句意，C選項(xiàng)的wish要加的賓語從句需用虛擬語氣，故選項(xiàng)D正確。

　　12．B　句意為：“在一個(gè)極冷的冬天的早晨，他已凍僵的尸體在一個(gè)偏僻的森林里被發(fā)現(xiàn)了。”freezing極冷的；frozen凍僵的，結(jié)冰的。

　　13．A　此題考查了詞語辨析。句意為：“Rogers退休之后，一段時(shí)間里對繪畫產(chǎn)生了興趣，但很快又失去了興趣。”take up從事，對……產(chǎn)生興趣；save up積攢；keep up持續(xù)，保持；draw up停下來。

　　16．A　由答語中的“I’m too slow”可知不贊同對方的提議，故用not likely“不可能”。

　　17．A　apply sth.to...“把……應(yīng)用于”為固定搭配。在本句中，applied to some other conditions為過去分詞短語作賓語補(bǔ)足語。

　　18．B　本題考查動詞辨析。demand 要求；acquire 獲得；accomplish 完成；achieve 達(dá)到。句意為：只有那些有耐心把簡單的事情做好的人才會獲得容易應(yīng)對難事的技能。

　　20．C　根據(jù)主句謂語動詞的時(shí)態(tài)可知從句時(shí)態(tài)應(yīng)與現(xiàn)在時(shí)有關(guān)，再結(jié)合狀語all morning可確定最佳答案。

　　21．A　available可利用的，常跟在修飾詞的后面；其他三項(xiàng)qualified(合格的)；standard(標(biāo)準(zhǔn)的)；impressive(印象深刻的)作定語常放在修飾詞之前，且與題意不符。

　　23．B　when此處為并列連詞，相當(dāng)于at that time，可譯為“這時(shí)(突然)……”。

　　24．D　respect除表示“對某人的意見，行為，品德及才華等的尊重”外，還表示“遵守某事物”。appreciate強(qiáng)調(diào)理解并欣賞其價(jià)值；regard指“十分尊重，并含有愛戴之意”。honour指公開表示尊重。由題意可知，空氣污染是由于一些工廠沒有遵守保護(hù)環(huán)境的制度。
