Many questions have been raised about GM food. No one really knows whether it is safe for animals or humans to eat.

关于转基因食品，人们提出很多质疑的问题。没有知道它是否适合动物和人类安全食用。

Scientists admit that more tests should be done on GM food.

科学家承认，关于转基因食品，还需要做很多实验。

Research has been limited to increasing production profits, rather than making sure that GM foods are safe.

目前的研究只局限于增加生产利润，而不是确保转基因食品的安全。

GM food could therefore be dangerous to eat. There is also a question as to whether GM plants are safe for the environment.

因此，转基因食品食用有危险。同样的问题，转基因植物对环境是否安全。

Since GM crops are planted outside, they are part of the food chain--insects and other animals eat them or use their products, and these insects and animals will be eaten by yet other animals.

由于转基因植物是种在户外的，它们也是食物链的一部分--昆虫和其他动物会吃它们或者利用它们的产物，这些昆虫和动物还会被其他动物吃掉。

No one knows what effects the GM material might have on the food chain.

没有知道转基因物质会对食物链产生什么影响。

Since no one really knows whether GM food is safe, many countries have hesitated¹ to give permission for the production of GM foods, as they would rather be cautious² with this new technology.

既然没有人确切知道转基因食品是否安全，对于生产转基因食品，很多国家都犹豫不决，因为对于这项新技术，他们宁愿小心谨慎。
