[不定项选择题]共用题干
FDA : Human , Animal Waste Threatens Produce
The biggest food safety risk for fresh fruits and vegetables as they are grown,picked or processed comes from human and animal waste,the US Food and Drug Administration(FD
A)said Friday.
More than 9,000 Americans die each year from food-borne diseases and some scientists believe fresh produce is the biggest carrier of contamination.
The FDA issued a set of draft guidelines for US and foreign growers to carefully monitor worker hygiene, water quality,manure management and transportation.
These 34-page draft guidelines urged growers to give workers lessons on basic hygiene such as using soap to wash their hands,covering wounds that could come into contact with produce,and using only clean toilets.
The FDA guidelines identified"the major source of contamination"for fresh produce as human or animal feces.
"We think just proper controls and proper attention to detail would make a big difference in food safety,"said an FDA official."It is our belief that these guidelines would not be very costly."
But grower groups disagreed with the FDA's assessment."Most food-borne disease outbreaks that happen further down the distribution line are due to contamination because people preparing food are not properly washing their hands,"said Stacey Zawal,an official with United Fresh Fruit and Vegetable Association."That is not necessarily true for growers and packers."
Some US grower organizations have expressed concern that the agency is interfering with on-farm practices.Others object to the FDA's proposal to have growers formally document the picking,handling and transportation of produce so that health officials could quickly recall foods if necessary.
Consumer groups criticized the FDA guidelines as of little use because they will not carry the force of law.But stricter regulations could evolve as researchers find new technology or methods to kill harmful bacteria or parasites,the FDA said.
The FDA recommendations are due to be made final by the FDA later this year for use by US and foreign growers.The matter of encouraging foreign growers to adopt the guidelines remains somewhat tricky but FDA officials say it is vital because of the huge amount of imported produce.
The last paragraph suggests that_.
A.some tricks need to be adopted to encourage foreign growers to follow the FDA guidelines
B.a good way should be found to encourage foreign growers to follow the FDA guidelines
C.foreign growers consider the guidelines to be of great importance to them
D.it is almost impossible to ask foreign growers to follow the guidelines

[简答题] Programming languages
Programming languages are how people talk to computers. The computer would be just as happy speaking any language that was unambiguous. The reason we have high level languages is because people can’’t deal with machine language. The point of programming languages is to prevent our poor frail human brains from being overwhelmed by a mass of detail.
Architects know that some kinds of design problems are more personal than others. One of the cleanest, most abstract design problems is designing bridges. There your job is largely a matter of spanning a given distance with the least material. The other end of the spectrum is designing chairs. Chair designers have to spend their time thinking about human bodies. Software varies in the same way. Designing algorithms (运算法则) for routing data through a network is a nice, abstract problem, like designing bridges. Whereas designing programming languages is like designing chairs: it’’s al
