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 vulnerableto 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 3℃, 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 turn greener. "Not only are the quantities of phytoplankton in the ocean changing." she said, "but the type of phytoplankton is changing."

Many facts suggest that children are overweight and the situation is getting worse, according to the doctors. I feel there are a number of reasons for this.
Some people blame the fact that we are surrounded by shops selling unhealthy, fatty foods, such as fried chicken and ice cream, at low prices. This has turned out a whole generation of grown-ups who seldom cook a meal for themselves. If there were fewer of these restaurants, then probably children would buy less take-away food.
There is another argument that blames parents for allowing their children to become overweight. I agree with this, because good eating habits begin early in life, long before children start to visit fast food shops. If children are given fried chicken and chocolate rather than healthy food, or are always allowed to choose what they eat, they will go for sweet and salty foods every time, and this will carry on throughout their lives.
There is a third reason for this situation. Children these days take very little exercise. They do not walk to school. When they get home, they sit in front of the television or their computers and play computer games. Not only is this an unhealthy pastime（消遣）, it also gives them time to eat more unhealthy food. What they need is to go outside and play active games or sports.
The above are the main reasons for this problem, and therefore we have to encourage young people to be more active, as well as steering them away from fast food shops and bad eating habits.What kind of children may eat more unhealthy food according to the text? （回答词数不超过6个）

Once upon a time, there was a scholar who wanted to gain more knowledge each day even though he had already gained enough knowledge. One day, he came to visit a saint and wanted to be his student. The saint provided some tea. He slowly filled the scholar’s cup: the cup was full, yet he kept pouring and pouring. The scholar burst out, “Stop! You can’t add anything to something that’s already full!” The saint set down the teapot and replied, “Exactly.”
Whether it’s the silence between notes in music, or some open time in your schedule, you need space to act effectively. Yet most of us, myself included, tend to stuff as much as possible into whatever room is available－closets, schedules, budgets, relationships, and even the mind itself.
However, some people know how to avoid overstuffing their life. For example, in Australia, it seemed that most people there operated at about 85% of their capacity（能力），unlike Americans pushing as close to 100% as possible. So when you run into Australians you know in the street, they have time to hang out and talk with you.
Remember the cup: its value is in the space, the emptiness it holds. How to empty your “cup”?
Be mindful of the element of space, openness , and emptiness in your life. This includes room in a drawer, the volume of air in a kitchen, and open-mindedness in a friend. Sometimes you’re just stuck with a big bucket of tasks yet to do. But at least empty the bucket faster than you fill it with new tasks. Put some space between finishing one thing and staring another. For example, after sending one email, take a breath before replying to another one. Drop the stuff you can no longer afford to lug around. At sea level, you can run with a brick in your backpack, but if you’re hiking on a mountain, that brick has got to go.By pouring water into the cup, the saint most probably wanted the scholar to know that.
| A．he should pay attention to details |
| B．he should keep learning every day |
| C．he had already gained enough knowledge |
| D．he should be very careful in order to succeed |
We learn that compared to Americans, Australians.
| A．work much harder |
| B．know less about their capacity |
| C．spare more time for themselves |
| D．spend less time with their friends |
The underlined word“lug”in the last paragraph probably means“”.
| A．reach | B．carry | C．see | D．show |

British English and American English are almost the same. But there are slight differences between British and American English in vocabulary, pronunciation, spelling and grammar.
The first difference between British and American English is in vocabulary. Almost all of the words used in British English and American English are exactly the same. Only a very small number of words are used disparately. For example, Americans would say “apartment”, but the British would say “flat” to talk about the place where they live. In addition to some common words, many idiomatic（惯用的）expressions are different. In England people might say “I’ll ring you up tonight”, but in the US, people might say “I’ll call you up tonight”.
The second difference between British and American English is in Pronunciation. The main difference in pronunciation concerns the vowels（元音）. Some American dialects and some British dialects use vowels in different ways. Sometimes, Americans and the British don’t understand each other’s pronunciation. But most of the time, the British and Americans do understand each other’s pronunciation because most of the sounds of the two dialects are the same.
The third difference is very small. This is the difference in spelling. A few types of words are spelled differently in British and American English. The most common example is in a word like “center”. In British English, this word would be spelled C-E-N-T-R-E, while in American English the same word would be spelled C-E-N-T-E-R. Another example is “or” vs “our”. The word “color”is spelled C-O-L-O-U-R in Britain but C-O-L-O-R in the US.
There are a few differences in grammar, too. The British may say “Have you got..?” while Americans prefer “Do you have..?” An American might say “my friend just arrived”, but a British would say “my friend has just arrived”. Sometimes function words are used differently: the British may say “at the weekend”, but Americans would say “on the weekend”.What is this passage mainly about?
| A．The development of American English |
| B．Differences between British and American English |
| C．The influences of British English on American English |

Hidden in a small street in the south end of Springfield, not far from buildings torn apart by the tornado（龙卷风） earlier this year, Frigo’s is an Italian restaurant right in our own backyard.
Frigo’s is not a tiny place. It provides different kinds of Italian food. There are refrigerator cases full of prepared foods and desserts, and shelves filled with olives and various pasta.
There’s some traditional Italian music and the smell is of olive oil and garlic（大蒜）. Above the largest refrigerator case, there’s a chalk board covered with desriptions of more Italian sandwiches than I could remember.
I stepped into Frigo’s almost by accident when I had to stay in Springfield into the evening for an open house at the school where I work. Frigo’s is the perfect place to find something quick to go. There are no tables, so all food is taken out. I also thought it would be a great place to pick up some already-prepared food to bring home for dinner.
I ordered the easiest meal possible: a chicken sandwich and a salad. It cost＄4.75 for the sandwich. The salad was＄4.99 and didn’t have salad dressing on it. I must have missed the choice of salad dressing on the way out. The sandwich was great—great chicken, excellent tomato sauce and not too much cheese.
I wish I had tried one of the many other sandwiches which include Joe’s Favorite (＄5.25-＄6.75) and the Dante (King) which is made of turkey breast, roasted red peppers, asiago cheese and choice of dressing.
I have a feeling that I’ll be picking up dinner for me and the kids at Frigo’s soon. Who would be most likely to go to eat at Frigo’s?
| A．People who want to eat quietly in a nice restaurant. |
| B．People who want to enjoy home-made food |
| C．People who like traditional American food |
| D．People who are fond of Italian food |
Which of the following cannot be seen at Frigo’s?
| A．A chalk board covered with descriptions of sandwiches |
| B．Refrigerator cases full of prepared foods and desserts |
| C．Shelves filled with olives and different kinds of pasta |
| D．Customers eating happily around tables |
How much did the writer pay for his first meal at Frigo’s?
| A．＄4.75 | B．＄5.25 | C．＄9.74 | D．＄4.99 |
We can infer that “Joe’s Favorite” and “Dante” are the names of .
| A．sandwiches | B．salads | C．cheese | D．peppers |
We can infer from the passage that the writer .
| A．seldom eats out in a restaurant with his family |
| B．feels very happy that be has found Frigo’s |
| C．dislikes eating sandwiches |
| D．lives a very relaxing life |
