Ⅱ．阅读理解
Australian scientists are trying to give kangaroo-style stomachs to cattle and sheep in a bid to cut the emission of greenhouse gases blamed for global warming.
Thanks to special bacteria in their stomachs，kangaroo farts contain no methane（甲烷）and scientists want to transfer that bacteria to cattle and sheep who emit large quantities of the harmful gas.
While the usual image of greenhouse gas pollution is a billowing smokestack pushing out carbon dioxide，livestock passing wind contribute a surprisingly high percentage of total emissions in some countries.
“Fourteen percent of emissions from all sources in Australia are from enteric methane from cattle and sheep，” said Athol Klieve，a senior research scientist with the Queensland state government.
“And if you look at another country such as New Zealand，which has got a much higher agricultural base，they're actually up around 50 percent，” he said.
Researchers say the bacteria also make the digestive process much more efficient and could potentially save millions of dollars in feed costs for farmers.
But it will take researchers at least three years to isolate the bacteria，before they can even start to develop a way of transferring it to cattle and sheep.
Another group of scientists，meanwhile，has suggested Australians should farm fewer cattle and sheep and just eat more kangaroos.
The_idea is controversial（争议），but about 20 percent of health conscious Australians are believed to eat the national symbol already.
“It's low in fat，it's got high protein levels and it's very clean in the sense that basically it's the ultimate free range animal（散养动物），” said Peter Ampt of the University of New South Wales's institute of environmental studies.
1．According to the passage，global warming is now mainly caused by ______.
A．methane
B．carbon dioxide
C．livestock passing wind
D．Not mentioned in this passage.
2．What does the underlined phrase “the idea”（Paragraph 9）refer to?
A．Australians should give kangaroo-style stomachs to cattle and sheep.
B．The bacteria could make the digestive process much more efficient.
C．Australians should farm fewer cattle and sheep and just eat more kangaroos.
D．The bacteria could potentially save millions of dollars in feed costs for farmers.
3．Some Australians begin to eat kangaroos because ______.
A．the kangaroos' farts（放屁）contain no methane
B．the kangaroos have a special bacteria
C．the kangaroos are the national symbol in Australia
D．the kangaroos are low in fat and high in protein
4．How will Australian scientists solve the problem of global warming?
A．Eating more kangaroos.
B．Killing more cattle and sheep.
C．Letting cattle and sheep pass less wind.
D．Transferring the special bacteria in kangaroos' stomachs to cattle and sheep.
意：当别人在与家属一起庆祝节日而自己却被遗漏，真是件痛苦的事。根据语意判断，B项正确。
12．D 句意：我们的车突然坏了，接下来的大雨使我们感到更无助。A项“分清，看清，辨别，理解”；B项“导致，引起”；C项“结果是，证明是”；D项“增添，添加”。根据句意可知应该选择D项。
13．D 考查动词。wear well此处意为“耐穿”，而sell well则意为“畅销”，均用主动形式表示被动意义。其他类似的动词有write，wash，read等。句意：“牛仔布，众所周知，是一种耐穿的布料，因此很畅销。”
14．D mustn't表示“禁止或不允许”，在此处是对may的否定回答。句意：——我可以把这本书带出阅览室吗？——不行。你就在这里读吧。
15．A 考查情态动词。was/were able to表示经过努力而做到的事情；could表示过去具备的“能力”，不表示具体做到了某事。
16．D 此题考查句型：It＋will/ would/ may be＋时间段＋before...，表示“要过多久才……”。句意：由于有一些技术问题要解决，这个系统可能还要再过一段时间才能投入使用。
17．C 过去分词（有时构成被动结构的过去分词）或构成进行时态的现在分词置于句首要引起倒装。例如：Visiting the Great Wall were 200 American college students.二百个美国大学生正在参观长城。综上所述，此题考查构成被动结构的过去分词提到句首引导倒装，正常语序为：Some Christmas gifts for her children are added to the shopping list.由此可知答案为C项。
18．B 在肯定句中，名词doubt后面接whether引导的同位语从句，在否定句中则接that引导的同位语从句；表示“处理；对付”时，deal with中的deal为不及物动词，而do（sth.）with中的do为及物动词，本身需要宾语，所以第二个空应选dealing；第三个空应选so与后面的that构成so...that...句型，引导结果状语从句。
19．C 根据句意可知，动词name“命名”和day（Learn from Lei Feng Day）之间为动宾关系，且过去分词作定语表示被动和完成，所以答案为C项。
20．C 第一个空应用现在分词carrying作状语表示伴随情况；第二个空应用turned，与hurried构成并列谓语。
管这一观点有争议，但目前约有20%健康意识较强的澳大利亚人已经吃上了被视为‘国家象征’的袋鼠”可知，这一观点指的是上文“澳大利亚人应少养牛羊，多吃袋鼠肉”，答案为C项。
3．D 从最后一段的第一句“It's low in fat，it's got high protein levels.”可知应选D项。
4．D 从文章第一﹑二段可推断，为了减少导致全球变暖的温室气体的排放，澳大利亚科学家目前正在想办法将牛羊胃变成袋鼠式的胃。袋鼠胃中有一种特殊的细菌能使其放的屁中不含有甲烷。科学家想将这种细菌移至牛羊的胃中，以抑制它们所排放的大量有害气体。
