Endangered species are animals that are on their way to becoming extinct. Some of the reasons why animals become endangered are caused by humans. 1. Forests and grasslands are being destroyed for farm land Pollution is another leading cause of endangered animals. Air, water, and land pollution can harm animals by destroying their living environment. 2. For example, the arrival of new animal species in an area can endanger wild animals. All the reasons above have caused more and more animals to become endangered. So we should take action to help them. Here are some useful ways.
First, plant trees. Trees recycle oxygen, returning it to the air for us to breathe. 3.
Second, pick up trash. Picking up trash not only protects the environment and keeps our surroundings beautiful, but it can also save wild animals by giving them a safer and cleaner environment. 4.
5. The population increase threatens the wildlife as our resources become fewer and fewer, which influences wild animals” living environment greatly. So keep an eye on the latest news about endangered animals and reach out our hands! By contributing money, things or just volunteering, we will play a valuable role in the protection of wildlife and in helping our earth!
A.Third, donate something.
B.One reason is the loss of habitat.
C.The third reason is the arrival of new animal species.
D.Third, learn about the latest information about wild animals.
E.They also help to create a complete and lively global ecosystem.
F.So pick up as much trash as we can to help protect wild animals.
G.There are other causes of endangered species that are indirectly caused by humans.
You already know many things that can reduce your chances of getting various types of cancer. Avoiding tobacco (烟草) products is an important thing, but have you ever considered your choice of dinner time as a reason for your risk of cancer? Probably not, but new research suggests that you might want to consider it.
A new study published in the International Journal of Cancer draws some very interesting connection between people’s time for dinner and their risk (风险) of developing certain types of cancers, including breast and prostate (前列腺) cancer, which are two of the largest killers of men and women.
“Modern life often means mistimed sleeping and eating that are connected with poor health effects in experimental studies,” the researchers explain. The research mainly focuses on how long before bedtime a person eats their last meal of the day. People who eat before 9 p. m or eat at least n couple of hours before hitting the sack have lower risks of developing cancers. The scientists find that these people enjoy a 20% drop in cancer risk when compared to those who eat dinner after 10 p.m. or eat right before climbing into bed.
The researchers followed the habits of thousands of people and tracked their nighttime eating habits and whether or not they developed cancer over the long term. The numbers seem to point towards early dinners being a very beneficial thing if you’re hoping to avoid some of the more common types of cancer, but the scientists still don’t know exactly why that’s true. At the moment they believe circadian rhythm (生物钟) is playing a role, though they can’t say exactly how.
1.Why are tobacco products mentioned (提到) in Paragraph 1?
A.To introduce the topic.
B.To make comparisons.

D.To show the harm of smoking.
2.What does the underlined part “hitting the sack” in Paragraph 3 mean?

3.What can we infer from the last paragraph?
A.The researchers didn’t have long-term research plans.
B.The researchers need further work to improve their study.
C.The researchers have confirmed the way of circadian rhythm works.
D.The researchers have found the real causes of some types of cancer.
4.What is mainly talked about in the passage?
A.Food and cancer. B.Tobacco and cancer.
C.Sleeping and cancer. D.Dinner time and cancer.
Google has reported progress in its plan called “Project Loon” to provide Internet service to rural (农村的) areas without Internet connectivity around the world. The company has no plans to use traditional wiring, which can be costly. Instead the idea is to float (漂浮) huge balloons (气球) about 20 kilometers above the surface of the Earth.
The balloons would act like telecommunications satellites, providing Internet service to the rural areas. The huge objects would ride air currents (气流) to either stay in place or move to another position high in the skies. At first, the idea was to have a large number of balloons circling the planet. One balloon would move away from an area while another arrived to ensure service in the affected areas. But the company said it has found a way to make balloons float over one area for a long period. In a report published online, the company said its software “can now send small teams of balloons over a specific area where people need Internet access.”
The company said some of the balloons stayed in the same area for as long as three months. The company also said the discovery should speed up the project and reduce costs: “We’ll reduce the number of balloons we need and get greater value out of each one, they said. But Project Loon workers must still find ways to increase the life of the balloons. A British Broadeasting Corporation report said the longest service for a single balloon was 190 days.
Google has also explored the idea of providing Internet service to rural areas using solar—powered drone aircraft (太阳能无人机). However, it gave up that project because of technological difficulties and high costs.
1.What’s the aim of the “Project Loon”?
A.To float huge balloons above the rural areas.
B.To help rural areas have access to the Internet.
C.To increase Google’s income in the rural areas.
D.To advertise Google’s new product in the rural areas.
2.Why wouldn’t Google use traditional wiring?
A.It could be too expensive.
B.It could put off the project.
C.It couldn’t provide greater value.
D.It couldn’t work for a long period
3.What do we know about the balloons?
A.They must be used in a large number.
B.They could provide service as long as 3 months.
C.They’ll be sent up by solar-powered drone aircrafts.
D.They would work like telecommunications satellites.
4.What is the passage mainly about?
A.An unexpected discovery.
B.Some unknown facts about balloons.
C.Google’s using balloons to provide Internet service.
D.The differences between the new and traditional wiring.

Everyone likes the beautiful Cinderella, but I like the ugly stepsister. The sidewalk was filled with shoppers as my mother and I hurried to the department store, I raised my neck for a look at the holiday window display, but at the age of six I was too small to see around the grown-ups with their winter coats and packages. When at last we reached the store, I stood with my eyes widened. “Look, Mother,” I shouted, pressing my hands against the glass, “Cinderella.” Before my eyes was the most beautiful doll I had ever seen! She wore a fairy princess suit made of shining red silk. I knew if I lifted her skirt I would find her crystal(水晶) shoes. The tiny tiara(冠状头饰) fastened to her silky golden hair shone.
“If only she were mine,” I dreamed. “We’d have tea parties, share secrets and dance with a handsome prince.” But to my disappointment, my mother guided me away from the window, explaining that she and my father could not afford such an expensive doll. “But there will be a very special gift under the tree for you on Christmas morning, Madge,” she said. “I promise.” Later that week I leaned against Mother’s sewing machine, watching the needle flash up and down. “Bet you don’t know what this is!” she joked, holding up the cloth for me to see.
“My Christmas doll!” I yelled. It was still in the early stages but I could make out the head, neck and body. “So much to my surprise!” Mother laughed as I danced around the room, already pretending Cinderella and I were at the ball. It wouldn’t be long now.
My excitement grew with each passing day. Mother continued to work on the doll, and whenever I walked into the room she would hide it under a pillow. I could tell by her smile she was pleased with her progress. On Christmas morning I jumped out of bed, ran down the hall and quickly arrived at the living room where the Christmas tree was placed.
