DearAuntieEm，Greatnews!Mrs.Mum-优题课

Paper is one of our oldest，simplest and most important inventions.It is the pride of us Chinese，but it also presents a danger to the world.

First，the making of paper requires the loss of many millions of trees each year.According to The World Counts，between 2001 and 2019，the world lost a total of 386 million hectares of forest.Of the trees that were cut down，42 percent went to paper production.That represents a great part of the world's forests.And worldwide use of paper is expected to double in the next 40 years.Clearly，the planet cannot keep such a high rate of forest Loss.

The second great problem with paper is that when the paper is used，it is useless.A great deal of wastepaper ends up in rubbish and even landfills （废物填埋场），where it can produce harmful gases.Paper in landfills causes the release （释放） of methane，a gas that is an important factor （因素） in climate （气候） change all around the world.

One simple way to help out can greatly reduce both of these problems：paper recycling.Instead of cutting down trees，recycle used paper to meet the need of paper﹣making.Effective recycling requires an effort from everyone all over the world.The way to begin is with education and understanding.Once enough people realize the need for recycling，more effective recycling systems can be put into use.

The need is real.The loss of tees influences everybody on earth.Everyone should do their part to recycle paper and encourage government and industry to do the same.The world will be a better place for it!

The teacher 　　（want to know） how many students would like to go to the zoo.

You look so smart!Your jacket 　　（go well with） the blue jeans.

The task is too difficult.Lucy has no c 　 but to ask others for help.

Does my goldfish know who Ian？

I think this is a great question.I do spend my days（1）　　（study）how fish go about their lives.First of all，fish are much smarter than people think.People often talk of goldfish having three﹣second memories，but in fact they can learn all kinds of things，and remember them（2）　　 quite a long time.

This shouldn't surprise us too much.Just like other animals,they can find enough to eat.And（3）　　(know) when it is sale to be out in the open.Being able to learn and remember things helps（4）　　（they） do this.

Many kinds of fish can tell one from another，according to their group，their relatives

（5）　　even their own eggs.But fish live in（6）　　 very different world from us，For many kinds of fish，although seeing is important，（7）　　（sense） such as smell and touch are even more important.

So，does your fish know who you are？I believe your fish will（8）　（sure） know when it is feeding time,My own fish become very（9）　　（excite）when my hand appears near their tank,even before I drop the food in.I'm not sure that your fish will be able to remember what your face（10）　　（look） like，but I wouldn't be too surprised if it could remember you in other ways，perhaps by the sound of your footsteps as you walk towards the tank.
