In 2012, James Cameron, creator of Avatar and Titanic, became the first person to reach the Challenger Deep. When he arrived at the deepest spot on Earth at 7 miles below sea level, he spent hours mapping the region and taking photos and samples.

“As human beings, we’re drawn to absolutes—the deepest, the highest, the coldest, the farthest.” he says. “And as a storyteller and curious monkey, I just wanted to see what was there.” The answer is obvious—plastic and more. “Our so-called civilization is using the ocean as its toilet,” Cameron says. “Unless this changes, ocean ecosystems are going to continue their rapid collapse.”

Despite decades of environmental studies, the impact of plastic and other forms of pollution on oceans are not entirely understood. Initial studies appear to indicate that ingesting them-either directly or indirectly-could cause disease. Plastics can also release poisonous substances into the water, which could potentially impact animal populations.

But plastic is just one of the problems facing oceans that have yet to be fully understood. “Plastic waste in the ocean is horrifying but is only the most obvious of our many deadly waste streams, which include carbon that’s heating the atmosphere and making the ocean acidic, and the run-off nutrients from all the world’s agriculture, which is causing anoxic dead zones the size of countries,” Cameron says.

Oceans, like the rest of the world, are impacted by the burning of fossil fuels and the release of greenhouse gases like carbon dioxide-about 30 percent of which is absorbed by the sea. This absorption causes ocean acidification, where the pH level is altered to become more acidic. As a result, it’s harder for some creatures to form shells and skeletons and countless species at the base of the food web can struggle to survive, which, scientists say, has the potential to cause huge disruptions to entire ecosystems. Indeed, ocean acidification is thought to have played an important role in Earth’s worst-ever mass extinction event 252 million years ago.

The effect of climate change on the world’s oceans will likely worsen in coming decades. Last June, scientists announced carbon dioxide levels had reached the highest levels since human records began. The last time carbon dioxide levels were this high was during the Pliocene era, between 3 and 5 million years ago, when global temperatures were about 4 degrees Celsius warmer than they are today. Current climate models suggest that if greenhouse gas emissions continue on their current trend, we may be on course to see 4 degrees of warming by 2100.

As a result, understanding the role oceans have on global systems is becoming more and more important.

Slow schools and slow education can refer to different aspects of education. Some people use the term slow schools to refer to schools that are attempting to bring slow food to the cafeteria or dining room. For others it has far more implications and includes aspects of connection to knowledge, tradition, moral purpose and all that is important in life. In this sense it refers to the curriculum (课程), the way it is delivered, the process of learning, management of the school, and even if school is the best vehicle through which to educate our children. So in this sense, it refers to bringing the slow movement into education.

In many Western countries that have Anglo-Saxon origins, governments and schools have strict control structures in place and schools are driven by standardised curricula with tests and targets to ensure uniform outcomes. The emphasis is on the outcome not on the process. The process is about things like how ideas are conceptualised, how can we support learning and the knowing of how to learn, as well as the love of learning and investigating.

Slow education is also about connection to knowledge and to learning—real learning. It is about doing no harm and having respect for all living and non-living things. Slow education is a concept of ‘ecological literacy’. Michael Stone and Zenobia Barlow have put together a collection of authors in Ecological Literacy: Educating our Children for a Sustainable World to give us ways to adapt to the way we live on Earth and the way we can educate our children to their highest capacities. This book is recommended to parents and educators who are engaged in creative efforts to develop new curricula and improve children’s ecological understanding. Slow education is about supporting our children to develop values and ethics (道德规范) that will enable them to live a joyous life in the slow lane.

The similarities of debate about Fast Food vs Slow Food and the debate about Fast Schools vs Slow Schools are self- evident upon reflection. Fast schools like fast food are not concerned with the process, preparation and connection. They are concerned with the standardised end product which in the case of schools is the results from standardised tests and targets, and in the case of food is the standardised hamburger or fried chicken etc. ,that look like all others the outlet produce quickly.

The process of education is not about supplying students with lumps of information to be repeated on demand. It is about enabling students to learn how to learn. It is also about giving them opportunities to hear what others have learnt (knowledge) and to then discuss, argue, and reflect on this knowledge to gain a greater understanding of its truth for them and of how this knowledge will be of use to them.

【小题1】What does the underlined phrase “uniform outcome” in Paragraph 2 mean?
A.The same results.B.The unique courses.
C.The positive effects.D.The special clothes.
【小题2】Why does the writer mention Michael Stone and Zenobia Barlow’s book?
A.To present the purpose of slow education.
B.To encourage people to develop new courses.
C.To prove slow education is popular among parents.
D.To offer materials to learn about ecological literacy.
【小题3】What can we infer from the passage?
A.Education is a mirror reflecting the world.
B.People should rethink what to teach in schools.
C.We should reflect on ourselves on a daily basis.
D.Better reading skills should be attained in school.
【小题4】What is the best title of the passage?
A.Slow Schools- connecting children to life.
B.Slow Food- -turning schools into a new style.
C.Slow Education- -helping students get better grades.
D.Slow Movement- -being different from the fast world.

Exposed soil isn’t part of nature’s master plan. Good examples where soil is naturally found with no plants growing in are beneath freshly removed trees, or where the ground has been burnt by a land fire. In these situations bare soil isn’t bare for long; within days seedlings () begin to appear and cover the ground. In a few months’ time, the scar is hardly noticeable.

Unlike these natural examples, ploughed (耕犁) fields and freshly dug gardens are obvious examples created by man. But, left to nature, even these bare soils soon turn green with a large number of tiny seedlings. In fields, gardens and on grasslands, roadside and sports fields, along streets and on paths and pavements, we are constantly battling to stop weeds from growing. All we are doing is stop the recovering powers of nature.

Whenever soil is exposed, weeds act like a kind of medicine to reduce the potentially harmful rays of the sun, so the sooner plant growth covers the soil over again, the better.

Weeds also help to improve the fertility (肥沃) of the soil. Their roots get the soil together, improving its structure and creating a more stable environment in which soil life can grow fast. Those weeds with a deep root draw up plant nutrients from deeper in the ground, making them available to plants growing near the soil surface. Above ground, the stems () of weeds help trap fallen leaves which break down into the soil, adding to the fertility of the soil.

As the soil becomes more fertile, different kinds of plants start to replace the “pioneering” weeds. Bushes move in to take the place by gradually shading them out, followed in turn by trees, which eventually push up through the bushes, finally shading them out too. Fallen leaves from the bushes and trees carry on the job of building soil fertility that was begun by those very first weeds that grew on the bare soil. Then, when one of these mature trees is removed in a storm, leaving a wound of bare soil in the earth, the whole process starts again.

【小题1】When will soil be left bare?
A.A land fire has just happened.B.A young tree is planted in.
C.No one ploughs the land.D.No crops are planted in.
【小题2】Which of the following prevents the bare soil from recovering?
A.Seedlings appearing in gardens.
B.Reducing harmful rays of the sun.
C.Removing weeds from pavements.
D.Replacing plants in sports fields.
【小题3】What can weeds do for the soil?
A.They create soil life.
B.They help improve the soil.
C.They get nutrients from the sun.
D.They break down fallen leaves.
【小题4】How can the soil remain fertile after trees move in?
A.By adding more weeds to the soil.
B.By taking out the weeds constantly.
C.By removing the previous bushes.
D.By making use of the fallen leaves.

History is full of tales of great ideas taking shape in sleeping minds; Paul McCartney said that he awoke with the tune of Yesterday in his head, and Robert Louis Stevenson said that the idea for The Strange Case of Dr Jekyll and Mr Hyde came to him in a dream.

Scientists believe that the mind at night puts together bits of information in creative ways. Throughout the day your brain rarely gets a chance to stop and think. It constantly responds to a stream of challenges, from writing a report for a work deadline to remembering where you left your car keys and figuring out what to buy for dinner.

“Think of your brain like a web," says Russell Foster, Professor of Neuroscience at Oxford University. "During the day the web is very tight, so you can only put information in a certain number of places. During sleep the web expands, and with the luxury of time, those bits of information can be put into lots of different places and make new associations."

He adds that this process may help to foster the formation of new ideas. "This bringing together of seemingly unrelated bits of information is vital to helping the brain think itself out of problems,” says Russell Foster.

"Sleep seems to allow your mind to make non-obvious connections. It puts all the information from the day into a big biological theatre and forces the mind to speak to people at the back of the theatre, who you may not think you have any connection with. This is the basis of creativity connecting ideas, events and memories that wouldn't normally fit together.

By placing volunteers into brain scanners and sending them to sleep, scientists have seen that the areas associated with emotion go into overdrive, especially while dreaming, while the areas that are responsible for logic (逻辑)are switched off. This not only explains why dreams are unbelievably random-you can be talking to a colleague one minute and the next minute sitting in your old school classroom dressed in your nightclothes—but also explains how the brain can put together different information.

【小题1】In what way are the mind at night and the mind during the day different?
A.The ways to receive information.
B.The ways to provide information.
C.The ways to process information.
D.The ways to exchange information.
【小题2】According to Russell Foster, what may bring out creativity?
A.Information put together in normal ways.
B.Information put together in unusual ways.
C.Information stored in a biological theatre.
D.Information stored in the mind.
【小题3】Which can replace "go into overdrive,, underlined in the last paragraph?
A.Start being active.B.Return to normal.
C.Stop working.D.Perform badly.
【小题4】What can be a suitable title for the text?
A.The Creative Power of the Brain
B.Great Works from Sleep
C.Never Believe Your Sleeping Minds
D.Sleep Can Bring Creative Ideas
