Long ago,there was a big apple tree.A little boy loved to come and play around it every day.He climbed to the top of the tree,ate the apples,and took a nap under the shadow...He loved the tree and the tree also enjoyed playing with him.
As time went by,the little boy grew up and he no longer played around the tree.
One day,the boy came back to the tree,appearing sad.“Come and play with me,” the tree asked the boy gently.
“I am no longer a kid;I won’t play around trees anymore,” the boy replied.“I want toys.I need money to buy them.”
“Sorry,but I don’t have money.However,you can pick all my apples and sell them.Then,you will have money.” The boy was so excited that he picked all the apples on the tree and left happily.The boy didn’t come back after that.
The tree was upset.
One day,the boy returned and the tree was so joyful.“Come and play with me,” the tree said.
“I don’t have time to play.I have to work for my family.We need a house for shelter.Can you help me ” “Sorry,I don’t have a house.But you can cut off my branches to build your house.” So the boy cut all the branches of the tree and left with delight.
The tree was glad to see him happy but the boy didn’t appear since then.The tree was again lonely and sad.
On a hot summer day,the boy returned and the tree was delighted.“Come and play with me!” the tree requested.
“I am sad and becoming old.I want to go sailing to relax myself.Can you give me a boat ” “Use my trunk to build the boat.You can sail and be happy.” So the boy cut the tree trunk to make a boat.He went sailing and did not show up for a long time.

Dear teachers and fellow students,
There is no doubt that our planet is getting warmer and warmer.Global warming has already brought about the rise of the sea level,the spread of diseases and the extinction of species.It’s our responsibility to live a low-carbon life to save the earth before it is too late.
Everyone is expected to cultivate the awareness of saving energy and resources.First,travelling by public transportation is an effective way to save energy and reduce the emission of carbon dioxide.Second,make full use of every drop of water.Also,try to avoid using disposable products like plastic bags.If you do use them,use them more than once.
Together,individuals can make a difference and every little thing counts!

Ⅵ.Many years later,the boy finally returned.Feeling tired,he went to see the apple tree.At the sight of him,the tree said regretfully,“I’m sorry,boy,but now I no longer have anything for you,no apples,no trunk.” “It doesn’t matter.I have no intention of getting anything from you this time.As you know,I’m getting old and nothing is better than a comfortable place to rest,” said the boy.Hearing this,the tree smiled with relief,adding,“My dying trunk is the right one for you.Please come here and have a seat.” The boy did as told and the tree burst into tears,due to the fact that she could still devote herself to her boy.
The apple tree is our mother.When we are young,she tries her utmost to take care of us and play with us.When we grow up,we leave her for some reason and only come back when necessary or in trouble.But she is always there,waiting for us and ready to offer what she owns without complaint.Never does she ask for rewards.Instead,it is our happiness that she desires for.So,try to put ourselves in her shoes and learn to show concern for her.Unit 6分层跟踪检测(一)Starting out & Understanding ideas

It should be one of the main goals in today’s society to reduce plastic consumption.Though many believe recycling will solve the problem,and continue using plastic,it’s actually the opposite.In 2013,254 million tonnes of trash was produced in the US alone,and only around 30% was recycled.This means the rest ended up in a landfill and will stay there for up to 1,000 years.
Now Asian countries,including Vietnam and Thailand,are looking for new ideas to avoid plastic.One of those ideas was a new,eco-friendly way to pack their goods by avoiding plastic packaging.One of Perfect Homes Chiangmai’s team members noticed a creative way to reduce plastic that a supermarket called Rimping Supermarket was using.Little did he know that people all around the world would absolutely love this idea.“I just entered to get a few items while we were waiting to sign some contracts with our lawyer,who was delayed.When I noticed the vegetables wrapped in banana leaves,I simply liked the idea.So I took a few pictures and posted them online,” he said.
With more than 3.5 million views and over 17 thousand shares,the idea became something people can encourage more supermarkets to implement(实施).
Some have noticed that not everything on the shelves is completely plastic-free to which the supermarket responded that they are taking one step at a time,but it’s not that easy.Many products come to the supermarkets pre-packaged and many companies are interested in wrapping their produce in plastic since it is the cheapest and the easiest option.
It’s now up to the shoppers to show the supermarket which they prefer.If everyone opts for the banana leaf packaging,they will probably stop stocking the items in plastic.
1.What can we infer about recycling from paragraph 1
A.The author thinks highly of recycling.
B.The US did a great job in recycling in 2013.
C.Recycling has failed to solve the plastic problem.
D.Recycling helps a lot in reducing plastic consumption.
2.Why did the man go to Rimping Supermarket
A.To buy some items.
B.To look for new ideas there.
C.To take photos of their shelves.
D.To sign a contract with a lawyer.
3.What does the underlined phrase “opts for” in the last paragraph probably mean
A.Doubts. B.Increases.
C.Dislikes. D.Chooses.
4.What is the best title of the text
A.Leaf Packaging Spreads Rapidly
B.Reducing Plastic Consumption
C.Recycling Avoids Plastic Packaging
D.A Good Option Makes a Difference

Grizzly bears,which may grow to about 2.5 m long and weigh over 400 kg,occupy a conflicted corner of the American psyche—we revere(敬畏) them even as they give us frightening dreams.Ask the tourists from around the world that flood into Yellowstone National Park what they most hope to see,and their answer is often the same:a grizzly bear.
“Grizzly bears are re-occupying large areas of their former range,”says bear biologist Chris Servheen.As grizzly bears expand their range into places where they haven’t been seen in a century or more,they’re increasingly being sighted by humans.
The western half of the U.S.was full of grizzlies when Europeans came,with a rough number of 50,000 or more living alongside Native Americans.By the early 1970s,after centuries of cruel and continuous hunting by settlers,600 to 800 grizzlies remained on a mere 2 percent of their former range in the Northern Rockies.In 1975,grizzlies were listed under the Endangered Species Act.
Today,there are about 2,000 or more grizzly bears in the U.S.Their recovery has been so successful that the U.S.Fish and Wildlife Service has twice attempted to de-list grizzlies,which would loosen legal protections and allow them to be hunted.Both efforts were overturned due to lawsuits from conservation groups.For now,grizzlies remain listed.
Obviously,if precautions(预防) aren’t taken,grizzlies can become troublesome,sometimes killing farm animals or walking through yards in search of food.If people remove food and attractants from their yards and campsites,grizzlies will typically pass by without trouble.Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away.“Our hope is to have a clean,attractant-free place where bears can pass through without learning bad habits,”says James Jonkel,longtime biologist who manages bears in and around Missoula.
5.How do Americans look at grizzlies
A.They cause mixed feelings in people.
B.They should be kept in national parks.
C.They are of high scientific value.
D.They are a symbol of American culture.
6.What has helped the increase of the grizzly population
A.The European settlers’ behavior.
B.The expansion of bears’ range.
C.The protection by law since 1975.
D.The support of Native Americans.
7.What has stopped the U.S.Fish and Wildlife Service from de-listing grizzlies
A.The opposition of conservation groups.
B.The successful comeback of grizzlies.
C.The voice of the biologists.
D.The local farmers’ advocates.
8.What can be inferred from the last paragraph
A.Food should be provided for grizzlies.
B.People can live in harmony with grizzlies.
C.A special path should be built for grizzlies.
D.Technology can be introduced to protect grizzlies.

Ⅳ.【语篇解读】这是一篇说明文。文章主要介绍了一种环保的包装物品的方式,能够尽量减少环境污染。
1.C 推理判断题。根据第一段中“It should be one of the main goals...and continue using plastic,it’s actually the opposite.”可知,回收利用并没有解决塑料消费这一问题。故选C项。
2.A 细节理解题。根据第二段中“I just entered to get a few items while we were waiting to sign some contracts with our lawyer,who was delayed.”可知,作者正等着和律师签订合同,律师迟到了,所以作者进来商场是想买点东西。故选A项。
3.D 词义猜测题。根据最后一段中“If everyone opts for the banana leaf packaging,they will probably stop stocking the items in plastic.”可知,句中banana leaf packaging表示“香蕉叶包装”,这是代替塑料包装的一种选择。可推测画线短语opts for表示“选择”,与chooses同义。故选D项。
4.D 主旨大意题。通读全文,文章提到了一种环保的包装物品的方式,这是一种选择,能够尽量减少环境污染,所以D项可以作为文章标题。故选D项。
【语篇解读】这是一篇说明文。文章主要介绍了生活在美国的一种让人又怕又爱的动物——灰熊。它体长可达2.5米,体重可超400千克。虽然如今灰熊的数量在增加,但仍在美国被保护动物的名单中。
5.A 推理判断题。第一段有两句话,第一句说明了人们的敬畏之情;第二句说明了人们的喜爱之情。因此mixed合适。故选A项。
6.C 推理判断题。本文的转折句,也就是灰熊的转折点,是第三段最后一句话“In 1975, grizzlies were listed under the Endangered Species Act.”,之后灰熊的数量由原来的600~800增加到了2000多。故选C项。
7.A 细节理解题。根据短文第四段最后两句“Both efforts were overturned due to lawsuits from conservation groups.For now, grizzlies remain listed.”可知,the U.S.Fish and Wildlife Service的两次尝试之所以被推翻,是由于灰熊保护群体的诉讼反对。故选A项。
8.B 推理判断题。根据最后一段第二句“If people remove food and attractants from their yards and campsites, grizzlies will typically pass by without trouble.”和第三句“Putting electric fencing around chicken houses and other farm animal quarters is also highly effective at getting grizzlies away.”可知,只要人们采取适当的措施,是能够与灰熊和睦共处的。故选B项。Unit 6分层跟踪检测(二)Using language
