    Birthday parties and graduations are occasions when people celebrate with balloons, often releasing (释放) them into the sky happily. But what happens to those plastic balloons once they become flat? Where do they end up?

For years, many environmental groups have pushed for mass balloon releases to be inhibited, saying that balloon pieces and strings are dangerous to wildlife. “They can bring harm to wildlife simply because they are colorful and bright, so wildlife might think they are delicious food, and their bodies can get caught by the strings, thus making it difficult for them to swim or breathe.” Emma Tonge, communications and outreach specialist at the National Oceanic and Atmospheric Administration, told USA Today. Yet releases still happen.

Researchers in Australia analyzed the effects that soft plastics like balloons have on seabirds. They have discovered that soft plastics are more likely than hard plastics to cause barriers in seabirds’ gastrointestinal tracts (胃肠道). Of the birds examined, nearly one out of five died as a result of swallowing a balloon or balloon pieces.

“If seabirds eat plastics, their risk of death increases, and even a single piece can be deadly,” wrote lead study author Lauren Roman, PhD student at University of Tasmania. “The evidence is clear that if we want to stop seabirds from dying from plastic ingestion (吸入) we need to reduce or remove marine debris (海洋垃圾) from their environment, particularly balloons.”

Balloons Blow, a nonprofit organization, is devoted to educating people about the dangers released balloons can have on animals, people and the environment. The group points out that all released balloons return to the ground as litter. Animals like birds, whales and sea turtles can die after swallowing balloons.

1.Why does wildlife eat balloon pieces?

A.They mistake them for delicious food. B.They eat anything for lack of food.

C.They feel like eating bright things. D.They suck them just for pleasure.

2.What does the underlined word“inhibited”in paragraph 2 most probably mean?

A.objected B.adjusted C.banned D.governed

3.What can we infer from the researchers’analysis in paragraph 3?

A.Seabirds are forced to swallow balloons.

B.Balloons mainly determine seabirds’survival.

C.Soft plastics are worse than hard ones for seabirds.

D.Seabirds are more sensitive to hard plastics.

4.What is Lauren Roman’s idea on the released balloons?

A.They have bad effects on all the birds. B.They are harmless in small pieces.

C.They are major damage to people. D.They do great harm to seabirds.

5.What is the text mainly about?

A.What released balloons bring to the ocean.

B.Why people should stop releasing balloons.

C.When action will be taken to protect wildlife.

D.How released balloons can be finally reduced.

 

1.A 2.C 3.C 4.D 5.B 【解析】 这是一篇说明文。文章讲述了释放气球对野生动物和海洋动物造成的危害。 1. 细节理解题。根据第二段关键句“They can bring harm to wildlife simply because they are colorful and bright, so wildlife might think they are delicious food, and their bodies can get caught by the strings, thus making it difficult for them to swim or breathe.”(它们可以给野生动物带来伤害,仅仅因为它们是丰富多彩的和明亮的,所以野生动物可能认为它们是美味的食物,它们的身体会被线缠住,从而使它们很难游泳或呼吸)可知,气球是色彩鲜艳的,野生动物误以为它们是美味的食物,所以吃掉了它们。故选A项。 2. 词义猜测题。根据划线词后句子“saying that balloon pieces and strings are dangerous to wildlife.”可知,这些环保团体认为气球碎片和绳子对野生动物很危险。根据他们的语言可以推断出他们是不支持释放气球的行为的,即希望这种行为被禁止,banned意为“禁止”。故选C项。 3. 细节理解题。根据第三段关键句“They have discovered that soft plastics are more likely than hard plastics to cause barriers in seabirds’ gastrointestinal tracts (胃肠道).”(他们发现软塑料比硬塑料更容易在海鸟的胃肠道中造成障碍)可知,研究员们发现,软塑料对于海鸟的伤害比硬塑料更大。故选C项。 4. 细节理解题。根据第四段关键句“If seabirds eat plastics, their risk of death increases, and even a single piece can be deadly”可知,Lauren Roman认为,如果海鸟吃了塑料,它们死亡的风险就会增加,即使一块碎片也可能是致命的。根据Lauren Roman的话,可以推断出她认为塑料制品对海鸟的伤害很大,而释放气球就会产生塑料垃圾,进而推断出她认为释放气球的行为对海鸟的伤害也是很大的。故选D项。 5. 主旨大意题。浏览全文,根据文章第三段中研究员的研究发现和第四段中Lauren Roman的研究发现可知,文章讲述了释放气球对野生动物和海洋动物是有很大危害的。根据第二段关键句“For years, many environmental groups have pushed for mass balloon releases to be inhibited, saying that balloon pieces and strings are dangerous to wildlife.”可知,为了野生动物的安全,许多环保团体认为释放气球的行为应该被禁止。综上所述,可推断出文章通过列举调查研究的结果告诉我们,为什么人们应该停止释放气球。故选B项。

    Nelda Billie has been waiting to turn on lights in her home for 15 years. ''We've been living off those oil lanterns,'' she says. ''Now we don't have to have flashlights everywhere. All the kids have a flashlight. When they get up in the middle of the night to use the restroom, they have a flashlight to go to the outhouse. ''

Billie, her husband and their five kids live in a tiny, one-room cottage built with wood and mud, which is a traditional Navajo home. Their three sheep are on the green grass that carpets the rolling hills of Dilkon, Ariz., on the Navajo Nation, the largest Native American reservation in the US. They watch two men in a cherry picker hook the last power line to their home.

Billie says they've gone through too many electrical machines to count. ''My two boys, they have really bad allergies and they have asthma(哮喘), so sometimes they need the sprayer. '' Billie says. ''So we usually go to their grandma's house, travel in the middle of the night over there back and forth. ''

The Billies are not alone. About 10% of Navajos on the reservation live without electricity. And as much as 40% of them have to haul their water far away and use outhouses. A poll(民意调查) of Native Americans conducted by NPR, the Robert Wood Johnson Foundation and the Harvard T. H. Chan School of Public Health found that more than a quarter of Native Americans have experienced problems with electricity, the Internet and with the safety of their drinking water.

Outside the Billies' home, the couple waits patiently for the workers to finish the job. Finally, after waiting for so long, the Billies watch the foreman turn on the meter behind their house and close the cover. Nelda then runs inside to open the switch. ''It's so exciting to finally have electricity here after so many years without it, '' Billie says. ''My kids are going to be so happy. They keep asking every day… They go, 'Mum, we're going to have light! We're going to finally have light! '''

Now the family will wait and pray for running water and the Internet.

2.What can we learn from paragraph 2?

A.The Billies lead a green but poor life.

B.Electricity can bring about great changes.

C.The situation of Native Americans is serious.

D.There is an urgent need for electricity in Billie's house.

3.How does Billie often find electricity to treat her children's illness?

C.By inviting workers to her house.

D.By going to her mum's house.

    Tess still stood hesitating like a swimmer about to make his dive, hardly knowing whether to return or move forward, when a figure came out from the dark door of the tent.It was a tall young man, smoking.

He had an almost black face, though red and smooth. His moustache was black with curled points, though he could not be more than twenty-three or-four. There was an unusual force in his face, and in his daring rolling eyes.

“Well, my beauty, what can I do for you?” said he, coming forward. And seeing that she was quite at a loss: “Never mind me, I am Mr. D’ Urberville. Have you come to see me or my mother?”

This differed greatly from what Tess had expected. She had dreamed of an aged and dignified face. She tried to keep calm and answered“I came to see your mother, sir.”

“I am afraid you cannot see hershe is ill in bed,” replied the representative of the house; for this was Mr. Alec, the only son of the noble family. “What is the business you wish to see her about?”

“It isn’t businessit isI can hardly say what!”

“Pleasure?”

“Oh no. Why, sir, if I tell you, it will seem…”

Tess’s sense of a certain ridicule was now so strong that, despite her general discomfort at being here, her rosy lips curved (弯曲) towards a smile, much to the attraction of the young man.

“It is so foolish,” she stammered(结结巴巴地说); “I fear I can’t tell you!”

“Never mind; I like foolish things. Try again, my dear, “ said he kindly.

“Mother asked me to come.” Tess continued; “and, indeed, I was in the mind to do so myself. But I did not think it would be like this. I came, sir, to tell you that we are of the same family as you.”

“Ho! Poor relations?”

“Yes.”

“Stokes

“No; d’Urbervilles.”

“Ay, ay; I mean d’Urbervilles.”

“Our names are worn away to Durbeyfield; but we have several proofs that we are d’Urbervilles. The local scholars hold the view that we are, and…and we have an old seal and a silver spoon marked with the same castle as yours. So mother said we ought to make ourselves known to you, as we’ve lost our horse by a bad accident; we can hardly make a living.”

“Very kind of your mother, I’m sure.” Alec looked at Tess as he spoke, in a way that made her uneasy.” And so, my pretty girl, you’ve come on a friendly visit to us, as relations?”

“I Suppose I have,” looking less confident and uncomfortable again.

“Well there’s no harm in it. Where do you live? What are you?”

——Tess of the d’Urbervilles By Thomas Hardy
