【題目】 This may look like an ordinary plastic straw (吸管), but it is not made of plastic. Cameron Ross started the Celise Bio-products company, to produce single-use plastic alternatives from plant materials like these. They are made of poly lactic acid (聚乳酸) known as PLA from com starches (淀粉).

Cameron Ross said, "We work with food service providers, mainly larger brands, to help them get quality sustainable and cost-effective solutions, made from plants to start getting rid of single-use plastics." Single-use plastics such as bottles or straws are major cause of pollution. When we throw these away, they end up in a landfill or in the water like rivers. According to researchers, it could take up to more than 500 years for them to properly break down.

Ross says he wasn't always so environmentally conscious himself. But ever since the hiking trip in West Virginia, when he spent more time picking up trash than enjoying nature, his priorities changed. That meant making biodegradable products that can break down in only a few years.

While many cafes and restaurants are choosing paper products to be more eco-conscious, it isn’t cheap. Paper straws can cost about eight times more than plastic straws. But bio-plastic straws cost less a penny a straw, not even double the price of plastic ones.

Another problem with paper straws is that they get soft and wet. You don't want to be sipping (啜飲) something that alters your drink, or starts to melt while you're drinking and then you have to get which creates more wastes than needed. Ross hopes his Washington DC-based company will provide an eco-friendly solution for food service providers.

【1】Which aspect is NOT the focus of the Celise Bio-products?

A.Material.B.Appearance.

C.Quality.D.Cost.

【2】What inspired Ross to start the Bio-products company?

A.High profits.B.Requests from food service providers.

C.Lower cost.D.His changed environmental awareness.

【3】What can we learn about the new straws?

A.They are widely used in cafes and restaurants.

B.They cost less than paper ones.

C.They may soften or even melt while carrying water.

D.They produce more waste.

【4】What's the author's purpose of writing the passage?

A.To persuade more food service providers to work with Ross.

B.To explain the development of straws.

C.To introduce a new eco-friendly straw.

D.To compare different straws.

【答案】

【1】B

【2】D

【3】B

【4】C

【解析】

本文是說明文。文章介紹了Cameron Ross創(chuàng)辦的Celise生物產(chǎn)品公司生產(chǎn)的一種新型環(huán)保吸管，以取代一次性的塑料吸管。

【1】

細(xì)節(jié)理解題。根據(jù)文章第一段首句“This may look like an ordinary plastic straw (吸管), but it is not made of plastic.”這種吸管外表看起來就像普通的吸管。由此可知，Celise生物公司并不關(guān)注新型吸管的外表。下文提到“to produce single-use plastic alternatives from plant materials” “.. get quality sustainable and cost-effective solutions(獲得高質(zhì)量、可持續(xù)、和低成本的解決方案)”，由此可知，他們注重使用植物原材料和產(chǎn)品的高質(zhì)量、低成本。故選B項。

【2】

細(xì)節(jié)理解題。第三段中提到“ever since the hiking trip in West Virginia, when he spent more time picking up trash than enjoying nature, his priorities changed. That meant making biodegradable products that can break down in only a few years.（但自從西弗吉尼亞州的徒步旅行之后，當(dāng)他花更多的時間在撿垃圾上，而不是享受自然時，他優(yōu)先考慮的事情就改變了。這意味著要制造出幾年內(nèi)即可分解的可生物降解產(chǎn)品。）”由此可知，是他的環(huán)境意識發(fā)生了改變，從而激勵Ross創(chuàng)辦生物制品公司。故選D項。

【3】

細(xì)節(jié)理解題。第四段中提到“Paper straws can cost about eight times more than plastic straws. But bio-plastic straws cost less a penny a straw, not even double the price of plastic ones. （紙吸管比塑料吸管貴8倍。但是生態(tài)塑料吸管每根便宜1美分，甚至還不到塑料吸管價格的兩倍）”。由此可知，生物塑料吸管比紙吸管便宜很多。故選B項。

【4】

推理判斷題。通讀全文，文章第一段提出“This may look like an ordinary plastic straw (吸管), but it is not made of plastic.”這種吸管不是塑料制成的，引出關(guān)于新型吸管的話題；文章第二、三段說明他創(chuàng)辦這家公司的原因是為了環(huán)保，第四、五段說明生產(chǎn)的生物塑料吸管在成本、質(zhì)量上與紙吸管相比較的優(yōu)勢。文章的目的介紹一種新型的環(huán)保吸管。 故選C項。

【題目】 I’d like to share a little story with you about something that happened when I was four. I remember it clearly. Our loving family dog was nearing the end of his life. My father picked him up and put him in a little bed we had made for him. Our dog, my companion, whom we had cared for, bit my father when he attempted to help him. How could he? Why? I couldn’t understand it. I didn’t like him anymore.

I hadn’t thought about that story for a long time but something that happened last week brought it back to me. I went to speak with a friend. When I knocked on the door, I met in an instant an angry look and a few harsh(尖刻的)words. When the door was slammed(砰地關(guān)上)in my face, I stood there shocked, and in a rush, I was reminded of my dog bit my father 20 years ago or so. What brought that story back was that same feeling of betrayal.

Both stories taught me something the next day. You see, when I got up in the morning and was told my dog had died, it became clear to me that he must have been in great pain. For him to have bitten a family member, he could not have been himself. Much the same for the other story when I learned that my friend’s wife had just left him.

We are all beings of our environments, our opinions and feelings. And all of those things can cause you to say and do things that can’t be understood by those who are not in the same situation with you.

If you meet someone either behaving out of character or acting in a way that doesn’t seem to fit the situation, put out your hand and be patient when you think it is least possible for him to do so. You may turn around a story that has a sad ending simply by your actions.

【1】What is the influence of the incident mentioned in Paragraph 1?

A.It hurt his father’s feeling deeply.B.It has puzzled the author ever since.

C.It left a deep impression on the author.D.It made the author dislike dogs.

【2】Why did the author’s friend say harsh words to the author?

A.He was ill-tempered.

B.He was suffering the pain of losing his wife.

C.He was bothered by an unexpected visit.

D.They once quarreled and he couldn’t forgive the author.

【3】What conclusion did the author get from the two stories？

A.Misunderstanding should be removed in time.

B.Sometimes one will be hurt without any reason.

C.Many people think more of themselves and less of others.

D.Many factors will affect one's behavior.

【4】What’s the author’s advice to us?

A.Help those in need.

B.Look before you leap.

C.Respect for others is a kind of virtue.

D.Learn to put yourself in others’ shoes.

【題目】閱讀下面材料,根據(jù)其內(nèi)容和所給段落開頭語續(xù)寫兩段,使之構(gòu)成一篇完整的短文。續(xù)寫的詞數(shù)應(yīng)為150左右。

A zoo keeper had been working at a zoo for 15 years and never experienced any problems. He always worked the evening shifts (夜班) because he was trusted to properly lock up the zoo. On a warm summer night in late June, the zoo keeper turned off the lights and wished all of his animals a good night. He left the zoo and walked to his car in the parking lot. As he reached in his pocket, he realized that his keys had been left in the office. He quickly walked back to the zoo.

When he arrived at the door, to his surprise, it was unlocked. In fear of triggering (觸發(fā)) the alarm that he had just set, he did not turn on the lights. He turned on the flashlight on his phone and began to make his way to the office. When he walked by the panther's (豹) cages, he saw the young cubs playing together. He liked the zoo better at this hour because at night was when the animals come to life.

At last, he made it back to the office. Unfortunately this time the office door was locked and he knew that if he were to break the window, he would set off the alarm. Knowing there was no way inside, he decided it would be best to spend the night inside the zoo. The zoo keeper walked towards the bird cages because he knew he could sleep comfortably on the benches near the cages.

A few hours later, the zoo keeper heard a door slam (砰的一聲) that woke him up.

“Quiet!" a voice whispered.

“What? There's no one here, another voice said. "The old man left hours ago”

"Alright, let's just grab the animals and get out of here.”

The zoo keeper didn't know what to do. He began to weigh his options: he could trigger the alarm but that would raise questions as to why he was inside, or he could face the thieves but that could potentially put him in danger. Then he turned the corner but made sure not to be seen so that he could see who had entered the zoo.

【題目】 Social media, magazines and shop windows bombard people daily with things to buy, and British consumers are buying more clothes and shoes than ever before. In Britain, the average person spends more than 1,000 on new clothes a year, which is around four percent of their income.【1】But it hides two far more worrying trends for society and for the environment. First, a lot of that consumer spending is via credit cards. British people currently owe approximately 670 per adult to credit card companies. That's 66 percent of the average wardrobe budget. Also, not only are people spending money they don't have, they're using it to buy things they don't need.【2】.

People might not realize they are part of the disposable clothing problem because they donate their unwanted clothes to charities.【3】Huge quantities end up being thrown away, and a lot of clothes that charities can't sell are sent abroad, causing even more economic and environmental problems.

【4】The idea originated in Canada in the early 1990s and then moved to the US, where it became a rejection of the overspending and overconsumption of Black Friday and Cyber Monday during Thanksgiving weekend.【5】Throughout the year, Buy Nothing groups organize the exchange and repair of items they already own. They send a clear message to companies that people are no longer willing to accept the environmental and human cost of overconsumption.

A.Fast fashion' goes out of fashion as quickly as it came in and is often too poor quality to recycle;

B.Britain throws away 300,000 tons of clothing a year, most of which goes into landfill sites.

C.The British people are deeply shocked by the unexpected statistics.

D.On Buy Nothing Day people organize various types of protests and cut up their credit cards.

E.However, a 'buy nothing' trend is springing up in opposition to consumerism.

F.That might not sound like much.

G.But charity shops can't sell all those unwanted clothes.

【題目】 More than half of the birds in Washington are at risk of extinction because of climate change. That's according to a new national report from the Audubon Society, which gives detailed analysis of climate effects on about 600 species of North American birds.

It's based on more than 140 million observations of birds across the US, Mexico and Canada. Audubon scientists looked at the likely effects of sea-level rise, urbanization, drought, extreme spring heat, increased fires, heavy rain and other factors.

But it doesn't just spell out a doomsday scenario (世界末日).Instead, it offers a range of effects and warming, depending on how much carbon humans add to the atmosphere.

"It is truly an existential threat (威脅), not only to birds but to people,” said Doug Santoni, board chair of Audubon Washington, who looked into the report as soon as it came out.

Santoni says he was struck to see the vulnerability (脆弱)of a common “ backyard bird" , the dark-eyed junco. It's one that many first-time birders become familiar with as they learn how to identify species based on their markings and other traits. Currently in Washington, you can count on juncos to show up at your feeder, year round. Extreme spring heat, increased fires and heavy rain are the kinds of changes that will force birds like these north, or kill them off if they fail to adapt.

Trina Bayard, director of bird conservation at Audubon’s Washington chapter, says, "It's certainly a very serious warning report," but adds that there’s still hope. “If we can stabilize current temperatures and decrease our emissions (排放), we can really reduce the effects to these birds …that's very motivating. ”

【1】What can we know about the new report?

A.It analyses the species of birds in detail.

B.It's issued by watching 600 bird species.

C.It shows the end of North American birds.

D.It reports the threat some birds are facing.

【2】What may Santoni probably agree with?

A.Climate change is a threat only to birds.

B.It's too late to take action to save the birds.

C.The current situation of the birds is worrying.

D.It's common that birds are affected by climate change.

【3】Which of the following can help these birds according to Trina?

A.Lowering present temperatures.

B.Reducing our daily emissions.

C.Making them adapt to climate change.

D.Encouraging people to protect them.

【4】What can be the best title for the text?

A.Climate change threatens many Washington bird species.

B.A new report about 600 species of North American birds.

C.Different attitudes towards the situation of bird species.

D.Climate change makes different kinds of species at risk.
