The latest results，published in the Annuals of Internal Medicine，suggest that buyers may be wasting their money．"We did not find strong evidence that organic food is more nutritious or healthier，"says Dr．Crystal Smith-Spangler from Stanford．"So consumers shouldn't assume that one type of food has a lower risk or is safer．"
For their new study，Smith-Spangler and her colleagues conducted a review of two categories of research，including 17 studies that compared health outcomes between consumers of organic against traditional food products，and 223 studies that analyzed the nutritional content of the foods，including key vitamins，minerals and fats．
While the researchers found little difference in nutritional content，they did find that organic fruit and vegetables were 20% less likely to have chemicals remaining on the surfaces．Neither organic nor traditional foods showed levels of chemicals high enough to go beyond food safety standards．And both organic and traditional meats，such as chicken and pork，were equally likely to be harmed by bacteria at very low rates．The researchers did find that organic milk and chicken contained higher levels of omega-3 fatty acids，a healthy fat also found in fish that can reduce the risk of heart disease．However，these nutritional differences were too small，and the researchers were unwilling to make much of them until further studies confirm the trends．
Organic food is produced with fewer chemicals and more natural-growing practices，but that doesn't always translate into a more nutritious or healthier product．The U．S．Department of Agriculture （USDA） states that"whether you buy organic or not，finding the freshest foods available may have the biggest effect on taste．"Fresh food is at least as good as anything marketed as organic．

A．should replace traditional food

D．is really more nutritious and healthier
（2）Smith-Spangler and her colleagues found that．
A．organic food could reduce the risk of heart disease
B．traditional food was grown with more natural methods
C．both organic and traditional food they examined were safe

（3）Which of the following is relatively healthier according to the passage？
A．Organic chicken and pork．
B．Organic milk and chicken．
C．Traditional chicken and pork．
D．Traditional fruit and vegetables．
（4）What is the author's attitude toward organic food？
A．Sceptical．

"In the future，we want to be able to power your wearable electronics without having to include a battery，" said Jianliang Xiao，an associate professor at CU Boulder.
The concept may sound like something out of The Matrix film series，in which a race of robots have enslaved humans to harvest their precious organic energy.Xiao and his colleagues aren't that ambitious：Their devices can generate about 1 volt （伏特）of energy for every square centimeter of skin space — less volt per area than what most existing batteries provide but still enough to power electronics like watches or fitness trackers.
Scientists have previously experimented with similar wearable devices，but Xiao's is stretchy，can heal itself when damaged and is fully recyclable — making it a cleaner alternative to traditional electronics. "Whenever you use a battery，you're depleting（消耗）that battery and will，eventually，need to replace it." Xiao said. "The nice thing about our device is that you can wear it，and it provides you with constant power."
Just pretend that you're out for a jog.As you exercise，your body heats up，and that heat will radiate out to the cool air around you.Xiao's device captures that flow of energy rather than let it go to waste. "The thermoelectric generators are in close contact with the human body，and they can use the heat that would normally be sent into the environment." Xiao said.
（1）What does Xiao expect of his device at present？
A．It will be used for medical purposes.
B．It will be made smaller and wearable.
C．It will change natural power into electricity.
D．It will supply constant power to wearable devices.
（2）Why does the author mention The Matrix series in the text？
A．To make a comparison.
B．To introduce a topic.
C．To give an explanation.
D．To analyze the cause.
（3）What does the third paragraph mainly talk about？
A．The replacement of wearable devices.
B．The strengths of Xiao's device.
C．The convenience of using a battery.
D．The development of traditional electronics.
（4）What do we know about Xiao's device from the text？
A．It operates with plenty of power.
B．It benefits people's health in a way.
C．It's based on traditional electronics.
D．It is designed for practical use.發(fā)布：2025/1/1 12:0:1組卷：19引用：2難度：0.51040．It is hardly surprising that clothing manufacturers（生產(chǎn)商） follow certain uniform standards for various features（特征） of clothes．What seems strange，however，is that the standard adopted for women is the opposite of the one for men．Take a look at the way your clothes button．Men's clothes tend to button from the right，and women's from the left．Considering most of the world's population----men and women----are right-handed，the men's standard would appear to make more sense for women．So why do women's clothes button from the left？
History really seems to matter here．Buttons first appeared only on the clothes of the rich in the 17th century，when rich women were dressed by servants．For the mostly right-handed servants，having women's shirts button from the left would be easier．On the other hand，having men's shirts button from the right made sense，too．Most men dressed themselves，and a sword drawn from the left with the right hand would be less likely to get caught in the shirt．
Today women are seldom dressed by servants，but buttoning from the left is still the standard for them．Is it interesting？Actually，a standard，once set，resists change．At a time when all women's shirts buttoned from the left，it would have been risky for any single manufacturer to offer women's shirts that buttoned from the right．After all，women had grown so used to shirts which buttoned from the left and would have to develop new habits and skills to switch．Besides，some women might have found it socially awkward to appear in public wearing shirts that buttoned from the right，since anyone who noticed that would believe they were wearing men's shirts．
（1）What is surprising about the standard of the clothing industry？
A．It has been followed by the industry for over 400 years．
B．It is different for men's clothing and women's．
C．It woks better with men than with women．
D．It fails to consider right-handed people．
（2）What do we know about the rich men in the 17th century？
A．They tended to wear clothes without buttons．
B．They were interested in the historical matters．
C．They were mostly dressed by servants．
D．They drew their swords from the left．
（3）Women's clothes still button from the left today because．
A．a(chǎn)dopting men's style is improper for women
B．manufacturers should follow standards
C．modern women dress themselves
D．customs are hard to change
（4）The passage is mainly developed by．A．a(chǎn)nalyzing causes B．making comparisons C．examining differences D．following the time order． 發(fā)布：2025/1/1 12:0:1組卷：44引用：2難度：0.1
