Thousands of bats(蝙蝠)in the Northeast are dying, and no one knows why. Scientists are conducting investigations(开展调查) to find out the cause and stop the spread of deaths, which have been most heavily reported in New York, Vermont and Massachusetts.

"Most bat researchers agree that this is the most serious threat to bats they have ever seen, " says Alan Hicks, a bat expert who works in the New York Department of Environmental Conservation.

There are few clues about the cause of the deaths. Bats are easy to catch the contagious disease(传染病) because they hibernate(冬眠) together. In some caves, there are 300 bats per square foot. Environmental officials are asking people to stay out of bat caves to avoid spreading the mysterious(神秘的) sickness while they are working to find out what it is.

Height is just one of the thousands of features your genes decide. In fact, because you have two parents, your genes provide you a height that usually lands somewhere between the height of each parent. If both your parents are tall, then most probably you will be tall, too, but if you have questions about how tall you're going to be, ask your doctor if he or she can help you find it out.
But genes don't decide everything. For example, eating an unhealthy diet can keep you from growing to your full potential(潜力). Getting plenty of sleep and enough exercise will help you grow to the expected height.
No doubt you're wondering how fast you should grow. It depends. There's no perfect or right answer. Generally speaking, kids grow about 2 inches (6 centimeters) a year between age 3 and the time when they start puberty (when your body starts changing and becoming more grown up).
Your doctor will know how your growth has been going over the years. Two centimeters here and 2 inches there are not nearly as important as the height you're at now, how you've been growing up to this point, and what other changes your body may be going through.
Don't be scared if you seem to have grown a lot in a very short time. Everyone has a growth spurt（高峰）during puberty. The age for starting puberty is about 10 for girls and about 11 for boys. But it can be earlier or later —-between 7 and 13 for girls and 9 and 15 for boys.
You'll usually begin to notice that you're growing faster about a year or so after your body starts to show the first changes of puberty.

How much do you know about A.I. (Artificial Intelligence)?Artificial means‘man-made', and intelligence means‘the ability to learn. understand and think about things'. A.I. is about making machines think, talk, do and see. A.I. is used in many fields from、playing games to helping doctors. Many machines around us work very well because they work with the help of A.I. Man has always dreamed of building‘thinking machines'. In 1770, Wolfgand Kempelen(1 734—1804)built a wooden robot called Turk that was able to play chess(SUR). It played very well and even beat some of the top chess players of the time! Later it was found that Turk was not real. Inside the box machine was a chess player.
John McCarthy(1927—)is thought as the‘Father'of A.I. He invented the word‘A.I.'and the LISP computer programming language that many A.I. developers use today. How does A.I. work?
A.I. uses ideas from many fields:

   Ask someone what they have done to help the environment recently and they will almost mention recycling, which is the process (过程) of treating used things, such as paper or steel so that they can be used again. Recycling in the home is very important of course. However, being forced to recycle often means we already have more things than we need. We are now dealing with the results of that over-consumption in the possible greenest way, but it would be far better if we did not bring so many things home in the first place.
   Here is an example. In the UK, the total of packaging increased by 12% between 1999 and 2005. It now makes up a third of a household's waste. In many supermarkets, foods are packaged twice with plastic and cardboard.
   Too much packaging causes serious environmental problems. The UK is running out of different kinds of ways for dealing with this unnecessary waste. If such packaging is burnt, it gives off greenhouse gases which go on to cause the greenhouse effect (效果). Recycling helps, but the process itself uses energy. The best way of avoiding this problem is to stop producing such unnecessary things in the first place. Food waste is another serious problem, too. Too many supermarkets encourage customers (消费者) to buy more than they need. They seldom encourage customers to reuse their plastic bags, for example. However, a few of them are coming round to the idea that this cannot continue.
   But this is not just about supermarkets. It is about all of us. We have learned to connect packaging with quality (质量). We have learned to think that something unpackaged is of poor quality. Is it true for all the products? In fact, more and more companies realized the importance of protecting the environment. They try to package what really should be packaged, including products in good quality.
   As more of us recycle, we are beginning to realize how many unnecessary things are being collected. We need to face the waste of our daily life. Although many people have taken action to recycle, we have a high mountain to climb.

The government in China ended his one-child policy and let families have two children instead in 2015.

A Chinese Communist Party statement gave a number of reasons for the change in policy. The statement said the change is meant to balance population development, stop a falling birth rate(出生率)and strengthen the country's labor force(劳动力). China, with the largest population in the world, started the one-child policy in 1980. But the government allowed only a small number of couples to have two children. For example, some families in the countryside could have two children, if the first-born is a girl.

In 2013, the Chinese government gave other couples a chance to have two children if one of them was an only child.

Jiang Quanbao, a teacher and population expert, explained how Chinese families react(反应) to the newest policy. "Too many young people in the cities are no longer interested in having a second child," he said. "People in the countryside are more interested. But some of them are already allowed to have two children." At the end of 2014, China had a population of 1.37 billion people. A total of 800 million of them have jobs. But the labor market need of labor by the year 2050. With the two-child policy, an increase in births can solve this problem.

Boys and girls, what do you think of the two-child policy? Do you want to have a new-born brother or sister?

Life in the future will be different from life today.

The population(人口) is growing fast. There will be more people in the world and most of them will live longer.

Computer will be much smaller and more useful, and there will be at least one in each home. And computer science will be one of the most important subjects in school then.

People will work fewer hours than they do now, and they will have more free time for sports, watching TV and travel.

Our food will be different, too. More land(土地) will be used for building new towns and houses for people. So there will be less land for cows and sheep, and meat will be more expensive. Maybe no one will eat it one day. They will eat more fruits and vegetables.

Work in the future will also be different. Robots will do dangerous and hard work. Because of this, many people will have no jobs to do. This will be a big problem in the future.
