By the end of the century, if not sooner, the world’s oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean’s appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerable to the ocean’s warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT’s Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 39C, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will tum greener.” Not only are the quantities of phytoplankton in the ocean changing,” she said, “but the type of phytoplankton is changing.”
And why does that matter? Phytoplankton are the base of the food web. If certain kinds begin to disappear from the ocean, Dutkiewicz said, “it will change the type of fish that will be able to survive.” Those kinds of changes could affect the food chain.
Whatever colour changes the ocean experiences in the coming decades will probably be too gradual and unnoticeable, but they could mean significant changes. “It’ll be a while before we can statistically show that the changes are happening because of climate change,” Dutkiewicz said, “ but the change in the colour of the ocean will be one of the early warning signals that we really have changed our planet.”

高一英语汉译英困难题查看答案及解析
Read the following passage and then answer the questions
Like so many teachers,I try hard to make each of my students feel they are special. I'm not a mother, so I look at my students as my children. In short year I have the opportunity to touch their lives. I want to teach each child that he or she is special because of who he or she is. During one year of teaching of fifth- grade class, I was shown how important my actions and lessons were.
It was toward the end of January when I started seeing notes passed around. This was unusual because the students had many opportunities to speak with each other while doing class activities. And because the notes were between students who weren't friends.There was not a certain individual initiator(发起人) of the notes nor was there just one receiver. They were simply circulating on a regular basis.
These notes were passed for a few days before I asked several students caught with them why they were being passed. I then lectured the whole class on their disrespect to me as I was trying to teach, while they passed papers. I didn't read the notes but placed them in the trash can.
After a week or two, I thought I had put an end to the note passing because the activity subsided. As January changed to February thoughts turned towards Valentine's day, but there was very little of the usual talk that goes on this holiday. The art teacher taught them to make big envelopes to hold their valentines and those were taped to the desks. I passed out a class list of names, so students could address their valentines. Finally on the day before the holiday, the students asked if they would be having a party. I asked them if they thought the last hour of the day would be a fair arrangement, and they agreed. Later they pushed for a 90 minute time period. And I gave them the old line, we will see how the rest of the day goes first.
On valentine's day we went through the morning lessons with no problem. I was surprised at how calm they were, considering what a holiday like valentine's day could do to ten-year-olds. Before the students went to lunch, I told them we would celebrate when we came back. They finally showed some excitement. When I went back to the cafeteria to pick my students up from lunch, they were not there.The assistant principal said the music teacher had taken them. I walked around the building to the music department and circled back toward the cafeteria. In the doorway was the music teacher who was waiting to greet me. The cafeteria had been cleared with the exception of one chair in the middle of the room. My students all stood before me on the stage as the music teacher walked me to the lone chair in the center of the room.
Candi, my shy little one spoke into the microphone. “We wanted to do something very special for you because you do so many special things for us. We had many ideas but decided you would like this one the very most. We have put together a talent show for you as our present. We hope you enjoy it.
Each student performed for me that day, there was dancing, singing, a roller blade routine set to music, a piano piece, a poetry reading. Every child did something in that show. I watched in disbelief. They had organized an entire variety show on their own. There was a master of ceremonies, props, scenery and equipment. All the notes that had been passed weeks before were plans for after school meetings to prepare and organize the show. They had asked for the help of the music teacher to help them get permission to use the stage and operate the sound system.
After an hour long performance to an audience of one beaming teary-eyed teacher, the show ended with all the students lined up on the stage. Together they said, “We knew the best gift we could give you would be a part of us. Happy Valentine's day.”
I have never felt so much love on valentine's day for the students and for being a teacher.

It was time to go home.“Remember to work on your class speeches for homework, ”Miss Walker called, as everyone started talking and packing their school bags. Jenny felt sick. She hated having to read aloud in class. She was sure everyone got really bored listening to her. Once, when Jenny was reading out her holiday diary, Lee was even looking at his watch, a silver and blue one which seemed just magical.
Jenny watched Lee walk ahead of her as they left school. He seemed so clever, and he had a certain sort of shining confidence. He was just one of those people who were good at everything. Jenny sighed. As she turned the corner, she saw Lee’s watch lying right in the middle of the path.
Jenny knew she should just pick it up and return it to him, but she didn’t want to run after him. Jenny bent down quickly, picked up the watch and ran home. On arriving home, Jenny put it on almost without thinking. She was surprised it fitted so well. She walked to the mirror and started practicing her speech. Words just flooded out of her.“I’m going to talk about swimming. I have been lucky. I’ve won lots of competitions. But when I’m in a race, I’m not really thinking about winning. I’m just loving the feeling of being in the water...”Jenny laughed with excitement. She walked across the room. She suddenly seemed to have a certain sort of confidence. Turning back to the mirror, Jenny saw a flash of light from the watch in the glass. The flashes of silver seemed almost magical. So maybe Lee’s watch really DID have something magic.
The next day, as the lesson began, Miss Walker asked who was going to be brave and go first. No-body moved. Jenny slowly raised her arm. Before Miss Walker could say anything, there was a shout from behind. “She’s stolen my watch!” Lee said angrily,“ It went missing at school yesterday.”

阅读下面短文,根据所给情节进行续写,使之构成一个完整的故事。
When Edith heard there was a competition to invent a brand-new machine, she longed to enter. Her idol (偶像), the famous inventor Mathew, was going to be the judge! Edith planned and worked on her invention every day after school. Finally, a huge light-up music box was finished—just in time for the competition. She was sure it would win first prize. Everyone would certainly be amazed when the lights shone and the music began to play.
However, when Edith slowly turned the handle (手柄), nothing happened. The machine needed more power.
Edith turned the handle faster, but no matter how quickly she went, she couldn’t get more than a flash from the lights. There was no way this would win and she had run out of time to fix it.
On the competition night, Edith went to the town hall with a heavy heart. She set up her music machine, feeling like a failure.
Mathew burst through the doors on his bike, whose pedals (脚踏板) gave off light. Everyone cheered excitedly. He got off the bike and walked around the rooms to see the inventions on show. Edith was nervous as he came over. “Can you tell me about your machine?” he asked. “It is a music machine that lights up.” Edith said in a low voice. Mathew clapped happily. “Amazing! Show me how it works.”
Edith turned the handle faster than she’d ever managed before. Terrible slow music started and the lights flashed on and off. Someone nearby laughed. Edith’s cheeks turned red. “Don’t worry.” Mathew smiled, “All my inventions went wrong when I was younger. You mustn’t give up.” Hiding behind the machine, Edith couldn’t wait for the competition to end.
The judging had almost finished when suddenly the lights of the hall went out. No one could get the lights to work and the competition couldn’t carry on. Edith thought for a moment. If only she were stronger, she could have turned the handle of her machine faster and lit up the room. In the dark, Edith could just see Mathew climbing onto his bike, with his pedals glimmering (发出微光).

You'll need to take a deep breath before hearing this news. An astonishing 93% of kids around the world live in environments with air pollution levels that are damaging their health, according to a new report by WHO.
Air pollution is to blame for the deaths of 543,000 kids under 5 in 2016, with more than one in four deaths of children under five years old being related to environmental issues. Exposure (暴露)to air pollution can damage the health of kids in a variety of ways, either causing or being associated with everything from low birth weight to childhood obesity and so on.
"The large toll of disease and death revealed (揭示)by these new data should result in an urgent call to action for the global community especially for those in the health department WHO stated. “ Strong action to reduce exposure to air pollution offers an opportunity to protect the health of children. " The report stressed that health experts should communicate with families , communities and policy-makers about the serious risks of air pollution exposure. " Although more researches into how air pollution affects children's health will continue to be valuable, there is already evidence to justify strong, swift action to prevent the damage it clearly produces," WHO added.
Disease caused by dirty air is more common in low-and-middle in come countries, especially those in Africa, South-East Asia, and Western Pacific regions. Poor countries in these areas have the highest levels of exposure to household air pollution due to the use of polluting fuels and technologies for basic needs like cooking, heating and lighting.
Advised solutions include cleaner transport , cleaner cooking and heating fuels and technologies energy-efficient housing and urban planning, safer industrial technologies and better waste management.

阅读下面短文,根据其内容写一篇60词左右的内容概要。
Getting up early has been regarded as a good habit since ancient times. Many years ago, people thought that if we went to bed early and got up early, we would be energetic the whole day. So, getting up early is of great importance to us all.
In fact, morning is the best time of a day. In the morning, the air is the freshest and people are usually in the best condition. Many of us may have the experiences that we memorize some things more quickly and correctly in the morning than at any other time of the day. And it is certain that we find it easier to understand what we learn in the morning. If we get up early and do some morning exercise or only take a short walk in the morning, without doubt we can build up our bodies and become much healthier. Also we will have enough time to make a plan and get ready for our work or study of the day if we get up early. For example, if everyone in the family gets up early, wives will have enough time to prepare the breakfast for the whole family; children will have enough time to catch the school bus, and husbands will never forget to change their dirty shirt. Everything will be in order. However, if we get up late, we’ll probably have to do everything in a hurry.
Let us remember getting up early is a good habit and try our best to keep it. Late risers may find it difficult to form the habit of getting up early. They have to make an effort to do so. If we stick to getting up early every day, we will certainly benefit a lot from it.
