Since the outbreak （爆发） of the pandemic（疫情），it has made its way around the world.
It has a strong influence on our daily life.People have found a way to protect themselves by wearing face masks （口罩）.We must wear masks anywhere in public.But the masks are one ﹣ time items.This means that we need to discard them after one or two uses.The world has seen wasted masks strewn （散布在） all over the streets and filling up garbage bins （垃圾箱）.
Experts have pointed out that the materials used in masks are difficult to degrade （降解）.It will take at least 100 years for them to degrade naturally.Environmentalists become quite worried because a countless number of wasted masks have ended up in the sea!They are polluting the sea!The sea animals suffer （遭受） a lot and so do we humans.If the sea animals eat them by mistake，the rubbish will be hard to digest （消化） and stay in their stomachs forever.The bacteria on the masks may.kill them too.They will not only largely influence the ecological balance （生态平衡） of the sea，but also can spread some more dangerous illnesses.People will also leave these harmful things in their own bodies and may become ill when eating these sea animals.
In general，the harm of wasted masks to the sea is serious，so we must take action to stop it right now.We should leave them in a safe place and find a wise way to recycle them.
（1）How do people protect themselves in the pandemic？
（2）What does the underlined word"discard"mean in Chinese？
（3）How long will it take for the wasted masks to degrade naturally？
（4）What should we do with these wasted masks？
（5）What is the writer's purpose of writing the passage？
There are only 24 hours in a day，and usually about a third of that is spent sleeping.So is it possible to make use of this time and learn a new skill or even a language？In other words，is sleep learning possible？
Many studies have found that a basic form of learning called conditioning can happen during sleep.In a 2012 study published in the magazine Nature Neuroscience，for example，Israeli researchers found that people can learn to connect sounds with smells during sleep.The scientists played a tone to sleeping study participants while putting some rotten（腐烂的）fish beside their beds.Once awake when hearing the tone.The people held their breath in anticipation of a bad smell.
"This was a dear finding showing participants formed new memories during sleep， " said Andrillon，a scientist in this held.
Although the now memory was implicit （暗示性的），it could influence how people behave，researchers found in a 2014 study published in the Journal of Neuroscience.In that research，after spending a night in a room full of cigarette（香烟） smell mixed with rotten eggs or fish，smokers use fewer cigarettes.
Andrillon and his team members have found that learning in sleep can also go beyond simple conditioning.In their 2017 study published in Nature Communications，participants were able to pick out sound features that they had heard during sleep.
Learning abilities in sleep may spread to learning of words.In a study published in Current Biology，researchers played pairs of made﹣up words and their supposed meanings like "guga" means elephant，to sleep participants.After this，when awake，the participants did better in picking the right translation of made﹣up words in a multi﹣choice test.
So far，research suggests it may be possible to learn about the tone and pronunciation of a language or even the meaning of words while sleeping，although it is to a weaker level than what we do during the day without noticing.

We are what we eat.From high﹣calorie meals to low﹣fat lunches，much of our health depends on what we eat.We know about the benefits（益处） of eating fittingly for our physical health，but food，and cooking it，is proving to be good for our mental（心理的） health as well.
Some people are now supporting the therapeutic value of cooking food.It's not just about the end result but also the experience someone goes through.Dr Mark Salter，a consultant psychiatrist，told the BBC： "Baking and cooking are good therapies.They help patients develop planning skills，short﹣term memories and social skills—lack（缺乏） of which may lead to mental illness."
TV chef（大厨） and author Nadiya Hussain agrees that cooking is great for helping our mind.She loves to bake and became the champion of the TV show，The Great British Bake Off.She says that "Baking's always been about therapy...It's never really been about the cake." And she thinks that baking is an important tool for our socialization and mental health.
Certainly，creating some delicious food takes our mind off things and gives us something to do，helping us get through the recent lockdown.People have said that mixing dough（生面团）to make bread，for example，has given them a sense of calm and control.Research has shown that doing creative tasks，like cooking，makes us feel happier.Nicole Farmer，who studies how food influences our biology，behavior and mental health，told BBC online that "Cooking represents the human experience of food，and growing people through food，so there is no doubt it can bring us timely positive feelings."
Of course，cooking can be a very sociable activity and sharing the end result，a rewarding experience.Hopefully，as we start to mix with friends and family again，we can enjoy the benefits once more and put us all in the right state of mind.

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!

Is it possible to have a diet（日常饮食）that's both healthy and friendly to our planet？Here are answers to your eco﹣friendly food questions.
Does what I eat influence climate（气候）change？
Yes.The world's food system is responsible for（为……负责）about one quarter of the planet﹣warming greenhouse gases that humans produce each year.That includes raising and harvesting all the plants，animals，and animal products we eat，as well as processing，packaging，and shipping food to markets all over the world.
Which foods have the largest influence？
In general，beef and lamb have the biggest climate footprint per gram of protein while plant﹣based foods like beans，rice，corn and wheat have the smallest influence.Pork，chicken，eggs are somewhere in the middle.

Look at the Earth from.space.Why does our planet look so blue？Its blue because water covers almost three quarters of the Earth's surface.Water is not just an important part of our planet.It is an important part of our body，too.More than half of our total body weight is water.
Our body loses water whenever we exercise or.go to the toilet.That's why we need to drink plenty of water every day.We drink water.We use it to cook，clean，and carry waste out of our homes.Farmers use it to grow vegetables and crops like rice and corn；factories use it to make products.
Since the 1950s，the amount（数量）of water people use has increased by three times.But the water supply（供应）hasn't.Scientists worry that soon there won't be enough water for us，as well as for the animals and plants that share our world.What can we do to help？Use water wisely.
Having enough water isn't our only problem. We also need it clean.
Right now，ships and factories are putting wastes into seas，rivers and so on.Even chemicals that farmers use are running into rivers and lakes.All this pollution can make the water dangerous to drink.It can also harm fish and other water﹣living lives.

Isn't fast food delicious？Aren't fast food restaurants cool？ ...The answer to these questions is yes.
However，there are growing facts that fast food is one of the worst parts of modern life.And studies have shown that burgers and fried chicken，which we enjoy so much，can cause a lot of health problems.
In spite of （尽管） this，why are fast food restaurants so attractive（吸引人的）？The first and most important reason is that their service is fast.Their staff（员工）are friendly and very smart﹣looking in their clean and bright uniforms（制服）.Moreover，most fast food restaurants are near places that people always pass by.It is so easy to graba burger and eat on the way to work.

As people realize the health problems that fast food causes，it is quite likely that fast food restaurants may go out of date.It may happen sooner or later.
Therefore，instead of resisting（抵制）fast food restaurants，a better idea may be to persuade（说服）them to change their menu!Fast food restaurants can be places to go to when you want to eat something that will be good for your body.If they could combine（结合）healthy food with their speed of service，delicious tastes and comfortable feelings，that will be the next best thing on the earth for the human beings!
