Up to 82 percent of children with healthy mothers are not easy to be obese, according to research. A mother, 【小题1】 has a healthy weight, exercises regularly, eats a healthy diet, doesn’t smoke cigarettes and 【小题2】(drink) wine in moderation, is significantly less likely 【小题3】(have) a fat child.

And research suggests it could be more to do with nurture (养育)【小题4】 nature, as a mother’s lifestyle appears 【小题5】(direct) linked to the health of her child. When both a mother and her child follow a healthy lifestyle, the risk of obesity 【小题6】(reduce) even more, the study of more than 24,000 children found.

The study examined the medical history and lifestyles of more than 24,000 children aged from nine 【小题7】 fourteen, born to almost 17,000 women in the US. Researchers studied the link between a mother’s overall health and likelihood of a child 【小题8】(be) obese.

The mother’s health is judged from her height-to-weight ratio (比例), her diet, amount of physical 【小题9】(active), smoking status and how much alcohol she drinks. A healthy weight and diet, regular exercise, no smoking and moderate drinking all reduce the chance of a woman having 【小题10】 obese child.

Imagine biting into a juicy burger that was produced without killing animals. Meat grown in a lab is turning that 【小题1】 (imagine) into a reality. Several companies are developing lab-grown beef, pork, poultry and seafood. And the field is attracting millions in funding.

If widely used. lab-grown meat, also 【小题2】 (call) clean meat, could reduce much of the cruel treatment of animals 【小题3】 are raised for food. It could also reduce the environmental costs of meat production 【小题4】 (great).

The meat 【小题5】 (produce) by first taking a muscle sample (样本) from an animal. Scientists collect stem cells from the sample and multiply (使繁殖) them to form more muscles. It’s said that one muscle sample from a cow can produce enough meat 【小题6】 (make) 80,000 hamburgers.

Many companies say they expect to have products for sale within the next few years. But clean meat will have to overcome 【小题7】 number of difficulties, such as reducing the cost and proving the safety 【小题8】 the meat before it appears on the market. The good news is that despite all these 【小题9】 (challenge), the clean meat companies are keeping trying. If they can succeed, clean meat could make our lifestyle 【小题10】 (green) and more ethical than before.

Eating a healthy diet is far from simple because we actually make the majority of our food choices 【小题1】 (base) on our preference. Many people don’t even know how great it feels to eat a healthy meal because they 【小题2】(make) bad food choices for too long.

To really understand the importance of forming healthy eating habits, you need to ask【小题3】 (you) a question. Why do humans need to eat? “The basic need for food could be compared to 【小题4】 (put) gas in your car. If you put the right fuel into your car, it will spring to life with a single turn of the key and run smoothly for a long time, but if you put soda pop and sugar in your gas tank, it’s going to ruin your car. In this sense, your car and your body are alike. They can both run well 【小题5】 the right kind of fuel but deteriorate (变坏) over time if you ignore their basic 【小题6】 (need) of fuel.

If you ignore healthy eating habits, you not only face 【小题7】 possible future of being over-weight but also run the risk of depression heart disease, diabetes, cancer, and so on. The choices you make each day, from what to eat for breakfast to whether or not to have an extra piece of pie, influence how you feel and perform, 【小题8】 makes a difference to everything you do. Once you believe eating 【小题9】 (health) is necessary, it’s time to make some changes to your diet. Instead of cutting out all the “bad” foods you currently eat, it’s much easier and safer 【小题10】(start) by adding more healthy foods to your diet gradually, such as fresh fruit and vegetables, whole grains, low-fat dairy products and nuts. In this way, you’ll be slowly replacing your bad diet with a good diet.
