When you buy cooking oil in the supermarket, you may notice that some brands are labeled as “GM (genetically modified)-free”. So, what is genetic modification? Are GM foods safe?
These questions have been put back into the spotlight recently. On Nov 19, the Food and Drug Administrati0n (FDA) in the US announced that it had approved the AquAdvantage salmon to go on the market, making it the first genetically modified animal to be approved as food anywhere in the world.
GM foods are plants or animals that have been given a gene from another plant or animal to make them stronger in some way. The AquAdvantage salmon contains a gene from another type of salmon that makes it grow faster.
Although the FDA has said “food from the fish is safe to eat”, some believe that scientists can’t completely understand the potential health risks of GM foods, simply because they’re so new. Others worry that the fish could escape into the wild and cause ecological problems.
GM crops have experienced the same controversy, even though GM technology cuts down on the use of pesticides on crops and increases yields.
While GM animals are new, GM crops have already appeared on our plates: A total of 28 countries in the world including the US, Brazil and India planted 181.5 million hectares (1.815 million km2) of GM crops in 2014, according to the International Service for tile Acquisition of Agri-biotech Applications. In China, we grow GM cotton and papaya and import GM soybeans, corn, rape, cotton and beets from abroad.
Due to safety worries, many countries have regulations for producing and selling GM food.
In European Union countries, each GM food must be approved before it can be used. This process can take up to 17 months. The origin of all GM foods must also be traceable, and all food with a GM content of more than 0.9 percent must also be labeled, according to EU website europa.eu.
The US is less strict about GM foods. According to FDA regulations, companies introducing new GM foods to the market should report them at least 120 days before release. The labeling is voluntary, except that a product cannot be labeled as “GM-free” if genetically modified materials are used.
In China, GM foods can only be produced after strict tests by the Ministry of Agriculture say that they are safe. All food that is made from GM crops or contains GM ingredients must be clearly labeled on the wrapper.

A. the gene that makes them grow faster can work on humans too

Modern smart phones are fast becoming the must-have item. But what’s in store for the next generation of smart phones?
Tired of carrying around that heavy wallet? Soon you won’t need to! The next generation of smart phones will have NFC technology, which lets you pay for things with your smart phones. All you do is enter your credit card information into your phone. Then, when you are in a shop that allows NFC payments, you just wave your phone over a special instrument at the checkout. The purchase is instantly charged to your credit card.
Ever seen someone wearing something and wished you knew where to get it? Soon it will be easy with PicCommerce, new technology that uses image-recognition software. Here’s how it works. If you see something you like, simply take a photo of it with your smart phone. Then, your phone will send the image to a special server, which will respond with information about where you can buy it and how much it will cost.
Sick of your smart phone battery going flat? With so many applications draining (消耗) the battery, the latest phones need to be charged every day. But next generation smart phones will come with built-in chips that can connect to an antenna (天線) in your home. And as long as your phone is within range of the antenna, you will be able to charge your smartphone wirelessly, even if it is in your pocket.
Worried about getting your smart phones wet in the rain? A company called Hz0 has invented WaterBlock, new technology that makes your phone completely waterproof. And it’s so effective that your phone will even work underwater.
Fed up with carrying a heavy phone around? Soon, you will be able to get a PaperPhone! “Flexible phones are the future,” said scientist Roel Vertegaal. So, what are the benefits of flexible phones? Well, it means that instead of carrying your phone in your pocket, you could wear it wrapped around your wrist, for example.
Of course, there is just the problem: with so much new smart phone technology around, you will soon need to buy a new phone!

請(qǐng)閱讀下面短文,并按照要求用英語寫一篇150詞左右的文章。
Cleanliness is important to academic success at one Chinese university where compulsory labor is part of a program designed to award class credits while teaching students with proper moral values.
During winter,the sky is still dark at 6:30 A. m.when the first year students in Trade and Management College in Zhengzhou begin sweeping the 165 acre campus and it can take up to an hour.
Mr.Sun,the university official,said labor is good for building character and promotes “the spirit of hard work.” Some students also claim that they are always proud of the clean campus.They never litter because they’ve been through the labor and understand that they should respect the fruits of labor of others.
Some students,however,are against it because they feel the demands of the cleaning program are a distraction.Some often show up late and hungry to their morning classes after rushing to sweep the campus and clean their rooms.
