    The microplastics(微型塑料) problem in the oceans has made its way to sea turtles in a big way. A new study has found microplastics in the stomach of every single turtle they tested—a total of 102 sea turtles.

The researchers tested more than 100 sea turtles from all seven kinds and three different oceans, and they were looking for man-made things less than 5 mm long. The most things the team found were fibers, which most likely came from clothing and fishing equipment.

“The influence of these particles on turtles is unknown,” said Emily Duncan. “Their small size means they can pass through the stomach without causing a problem, as is frequently reported with larger plastic pieces.”

The researchers found more than 800 man-made particles in the turtles, but since they only tested part of the stomach, they believe the total number of particles could be 20 times higher. They don’t know how the turtles take in the particles, but they think they are from polluted seawater and polluted plants.

Professor Brendan Godley said that eating microplastics isn’t the biggest problem to sea turtles at the moment, but it is a clear sign that we need to do a better job watching global waste.

This turtle study shows that we need to reduce the amount of plastic waste, so we can keep clean and healthy oceans for future people.

1.The underlined part in paragraph 1 probably means “________”.

A.has gone into B.has made great effect on

C.has been walking to D.has tried to escape from

2.How did the researchers find out the microplastics problem

A.By giving examples. B.By comparing sea life.

C.By studying different sea animals. D.By testing turtles from different seas.

3.What can be inferred from Emily?

A.Larger plastic pieces cause trouble to sea turtles

B.Eating microplastics is the biggest danger to sea turtles

C.Scientists know clearly how sea turtles eat plastic pieces

D.The number of particles inside sea turtles is much higher

4.The purpose of the text is to call on people to ________.

A.stop killing sea animals B.find out more plastic waste

C.control pollution to oceans D.carry out further researches

 

1.B 2.D 3.A 4.C 【解析】 这是一篇说明文。一项新的研究发现,他们检测的总共102只海龟里,每只海龟的胃里都有微塑料。研究人员通过测试来自不同海域的海龟,发现了这一微塑料问题。微塑料因为颗粒小,可以顺利通过海龟的胃,从而对海龟造成危害。研究人员认为海龟体内这些颗粒数量更高,颗粒主要来自被污染的海水和被污染的植物。文章主要为了号召人们控制对海洋的污染。 1. 词义猜测题。根据后文A new study has found microplastics in the stomach of every single turtle they tested—a total of 102 sea turtles.可知一项新的研究发现,他们检测的总共102只海龟里,每只海龟的胃里都有微塑料。由此可知,海洋中的微塑料问题已经在很大程度上影响到了海龟。故划线短语意思为“产生影响”。故选B。 2. 细节理解题。根据第二段中The researchers tested more than 100 sea turtles from all seven kinds and three different oceans, and they were looking for man-made things less than 5 mm long.可知研究人员测试了来自7种和3种不同海洋的100多只海龟,他们正在寻找长度小于5毫米的人造物体。由此可知,研究人员通过测试来自不同海域的海龟发现了微塑料问题。故选D。 3. 推理判断题。根据第三段“The influence of these particles on turtles is unknown,” said Emily Duncan. “Their small size means they can pass through the stomach without causing a problem, as is frequently reported with larger plastic pieces.”可知“这些颗粒对海龟的影响尚不清楚,” Emily Duncan说。“它们的小尺寸意味着它们可以顺利通过胃,而不会有任何问题,而对于较大的塑料来说,这是一个经常被报告的问题。”由此可推知,大的垃圾会对海龟造成问题。故选A。 4. 推理判断题。根据最后一段This turtle study shows that we need to reduce the amount of plastic waste, so we can keep clean and healthy oceans for future people.可知这项对海龟的研究表明,我们需要减少塑料垃圾的数量,这样我们才能为未来的人类保持清洁和健康的海洋。结合文章,由此可推知,这篇文章的目的是号召人们控制对海洋的污染。故选C。

    Named after Camp Creek Road, its place of origin, the fire started on November 8, 2018 and killed at least 71 people. More than 1,000 people are reported to be missing, although officials say that number could increase.

The fire has been heavily sweeping the Sierra Nevada forest since last Friday, according to the California firefighting office, Calfire. 1,500 firefighters were sent to the affected area, but difficult conditions have prevented their activities and access to the area.

The fire has had huge fuel(燃料) as a result of wood from dead trees—27 million died last year after years of dry weather — plus leaves and grass dried by heat.

Evacuations(疏散) were ordered in several camps and in other areas. Calfire asked people to get ready to escape, considering high temperatures for the next few days.

The fire forced the shutdown of a highway and one of the entrances to Yosemite National Park. Meanwhile, scores of people have become sick and the air in northern California has been listed the world’s worst.

Heavy rain is coming next week that could reduce the flames but also bring floods on hillsides.

According to experts, the main causes of the wildfires are the weather, climate change and population change.

1.Where did the fire happen at the beginning?

A.Calfire

B.Sierra Nevada

C.Camp Creek Road

D.Yosemite National Park

2.What made the fire continue?

A.Climate change.

B.Firefighters’ action.

C.People’s evacuation.

C.The Yosemite National Park was closed.

    My grandma was the best grandma a girl could have. She never said a bad word about anyone. She always found good in a person.

When I was young, Grandma worked hard all spring and summer to buy a new coat for the winter. She sold eggs, fruit and anything her garden produced to earn enough money. Her old coat had seen better days, and she had repaired it quite a few times. When she finally had enough money saved up, off to town we went. Grandma looked so nice in her new coat, and I was proud of the hard work she did to earn it.

That winter, in the small town where she lived, a family with three small girls lost their house in a fire. They needed clothes, food and household items. Grandma decided to cut up her new coat and make three coats for the little girls. I asked her not to do it, but she kissed away my tears. She told me those girls needed coats much more than she did. Grandma made the dolls, coats, and apron on her old sewing machine.

When they were done, we loaded up the small red truck with the coats, an apron for the mother, blankets, food, and three little dolls. When the family saw what was in the truck, the mother started crying and the girls hugged the dolls.

On Sunday, Grandma wore her old coat to church and she was the nicest grandma there.

1.What did Grandma do to get herself a new coat?

阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。续写的词数应为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 (触发) 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 () 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 (砰的一声) 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.
