Question

17．In normal conditions，bread will go mouldy（霉）in around 10 days．But an American company says it has developed a technique that will keep the bread mould free for two months．
At the laboratory or Texas Tech University，chief executive Don Stull showed off the long，metallic microwave device．Originally designed to kill some bacteria，the researchers discovered it could kill the mould spores（霉孢）in bread in 10 seconds．"We treated a slice of bread in the device，we then checked the mould in the bread over time，"he explained．"And at 60 days it had the same mould content as it had when it came out．"
The machine uses much the same technology as found in commercial microwaves-but with some important differences，according to Mr．Stull．"We introduce the microwave frequencies in different ways，through a radiator．We don't get the hot and cold spots you get in your home microwave．"
The device has attracted plenty of bread manufacturers-but it is worried that it could push up costs in an industry．And there is also a concern that consumers might not take to bread that lasts for so long．
Mr．Stull acknowledges it might be difficult to convince some people of the benefits．"We'll have to get some consumer acceptance of that，"he said．"Most people do it by feel，and if you still have that quality feel，they will probably accept it．"
Mr．Stull believes that the technology could affect bread in other ways．He said that bread manufacturers added lots of additives（添加劑）to fight mould．As a result，they must add extra chemicals to mask the taste of them．If bakers were able to use the microwave technology，they would be able to avoid these additives．While a wholesale change in the bread industry might be difficult to achieve，there may be more potential with other foods．
71．The microwave device was originally designed toB．
A．make bread tasty            
B．kill some bacteria
C．kill the mould spores           
D．check mould in bread
72．What do the metallic device and commercial microwaves have in common？C
A．they both can kill mould spores
B．They both function through a radiator．
C．They both use microwave technology
D．They both can be used as a bread bakery．
73．According to Mr．Stull，the microwave technologyC．
A．may push up costs in the bread industry
B．will keep the bread more tasty after 60 days
C．can help bakers to avoid adding additives
D．might probably bring no benefits to consumers
74．What does the underlined word"them"refer to？B
A．Chemicals．B．Additives．C．Manufacturers．D．Foods．
75．It can be inferred from the text thatD．
A．bread made with the technology will have different taste
B．bread industry will pay no attention to the technology
C．the technology is as harmful as the additives
D．the technology is likely to be used more widely．

Answer 1

分析 本文是一篇科教類閱讀，主要講了微波技術(shù)的新用途．

解答 71-75．BCCBD
71題答案：B考查細節(jié)推理，根據(jù)文章第二段的Originally designed to kill some bacteria…（最初被設(shè)計用于消滅細菌…）可知本題答案為B選項．
72題答案：C考查細節(jié)推理，根據(jù)第三段的The machine uses much the same technology as found in commercial microwaves…（該機器使用了很多與商業(yè)微波中發(fā)現(xiàn)的同樣科技…）可知本題答案為C選項．
73題答案：C考查細節(jié)推理，根據(jù)文章最后一段的If bakers were able to use the microwave technology，they would be able to avoid these additives．（如果面包師能使用這種微波技術(shù)，他們將能夠避免這些添加劑）可知本題答案為C選項．
74題答案：B考查細節(jié)推理，根據(jù)劃線單詞所在的句子He said that bread manufacturers added lots of additives（添加劑）to fight mould．As a result，they must add extra chemicals to mask the taste of them．他說面包生產(chǎn)商添加大量的添加劑來防止霉，如此一來他們必須添加額外的化學(xué)物質(zhì)來掩蓋"它們"的味道．可知這里的they指的是"食品添加劑"，故本題答案為B選項．
75題答案：D考查細節(jié)推理，根據(jù)最后一段的最后一句While a wholesale change in the bread industry might be difficult to achieve，there may be more potential with other foods．雖然面包產(chǎn)業(yè)的完全改變難以實現(xiàn)，但是其它食品方面有更多的潛能（將微波技術(shù)運用于其它食品）．故本題答案為D選項．
