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（添加剂）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 本文是一篇科教类阅读，主要讲了微波技术的新用途．

解答 71-75．BCCBD
71题答案：B考查细节推理，根据文章第二段的Originally designed to kill some bacteria…（最初被设计用于消灭细菌…）可知本题答案为B选项．
72题答案：C考查细节推理，根据第三段的The machine uses much the same technology as found in commercial microwaves…（该机器使用了很多与商业微波中发现的同样科技…）可知本题答案为C选项．
73题答案：C考查细节推理，根据文章最后一段的If bakers were able to use the microwave technology，they would be able to avoid these additives．（如果面包师能使用这种微波技术，他们将能够避免这些添加剂）可知本题答案为C选项．
74题答案：B考查细节推理，根据划线单词所在的句子He said that bread manufacturers added lots of additives（添加剂）to fight mould．As a result，they must add extra chemicals to mask the taste of them．他说面包生产商添加大量的添加剂来防止霉，如此一来他们必须添加额外的化学物质来掩盖"它们"的味道．可知这里的they指的是"食品添加剂"，故本题答案为B选项．
75题答案：D考查细节推理，根据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．虽然面包产业的完全改变难以实现，但是其它食品方面有更多的潜能（将微波技术运用于其它食品）．故本题答案为D选项．
