Scientists in London say they have found the best diet for both humans and the planet. If the world followed the so-called "planetary health" diet, the scientists told Reuters that each year more than 11 million early deaths could be prevented. Scientists say that the way we produce and eat food is very bad for the planet. For the health of the planet, they claim the same diet would reduce greenhouse gases and save more land, water and animals.

Tim Lang, a professor at Britain's University of London, co-led the research. He told Reuters, "The food we eat and how we produce it determines change what we eat and the way we eat by "improving food production and reducing food waste."

Well, what do you eat on the planetary health diet? The scientists who created this diet say it is largely plant-based but still has small amounts of dairy, fish and meat. The diet calls for cutting red meat and sugar by 50 percent and doubling the amount of nuts, fruits, vegetables and legumes.

Food situations around the world are not equal. In certain areas, this would mean great changes. People in North America, for example, eat 6.5 times the recommended amount of red meat. On the other hand, people in South Asia eat only half the amount suggested by the new planetary health diet. Meeting the targets for vegetables would need big changes in other areas. In sub-Saharan Africa, people on average eat 7.5 times the suggested amount of vegetables like potatoes and cassava.

The scientists admit their goal will be difficult to achieve. But for them doing nothing is also not an option. Willet said, "If we can't quite make it, it's better to try and get as close as we can."

Scientists have announced that they have cloned the first human embryo. This has caused much debate round the world. On the one hand, some scientists point out that if you clone an embryo, you can produce valuable human tissues—such as bone or lung tissue—that could be used to save human lives. On the other hand, many people, including some scientists, disagree and are afraid that, if mankind toys with nature in this way, we may be on our way to producing a real-life Frankenstein’s monster.

Cloning is producing an exact copy of a plant or an animal using its cells. The first mammal to be cloned successfully from an adult cell was Dolly the sheep. She was born in 1996 and died in early 2003, at a much younger age than normal. When she was born, many people were worried that cloning would lead to more diseases in the animal world. However, in general the scientists were praised for their wonderful scientific advance.

Ian Wilmut, the Scottish scientist who created Dolly, is shocked that some scientists are now considering cloning human beings. Although he researches cloning, his intention has never been to create copies of humans. Instead, he thinks research efforts should concentrate on creating new tissues and organs that can be used to cure diseases like cancer. However, some people believe that cloning human embryos with the intention of destroying them shows no respect for human life.

Even though human cloning is causing a lot of anxiety, it is good news for Faye Wilson, a 41-year-old saleswoman who cannot have a baby. “I am anxious to have a child of my own,” she says. “I don’t want to adopt someone else’s child—if I had the chance, I would have a cloned baby right now.”

While cloning human embryos is not legal in many countries, some scientists are already pushing ahead with research in order to produce a cloned human baby. Severino Antinori, an Italian physician, has declared that he wants to be the first to clone a human being.

In the last few decades, scientists have reached consensus and reported that human beings are causing changes in the Earths climate.

In the last 50 years, gases pumped into the Earth’s atmosphere by the factories and vehicles have been speeding up the process of global warming and affecting our climate, Global warming refers to an average increase in the Earths temperature that, in turn, leads to climate change. If we continue to produce carbon dioxide and other gases in such huge quantities, we are expecting severe consequences. Recent reports have warned that global warming will cause terrible climate changes including more frequent flooding, heat, waves and droughts. Serious disease will spread and industries that rely on nature will be badly affected. Increased temperatures will also cause the polar ice to melt, raising sea levels and flooding many islands and cities. How can we stop these disasters from happening?

Government all over the world should take on the responsibility, but this is no easy task. Some governments express reservations about whether global warming is really caused by human activities. Many people believe that they are simply not prepared to give up the amount of money they make from industry to save the earth.

But why wait around for governments to take action? Experts say that each person plays their part. They suggest making small changes like taking public transport, recycling using low-flow shower heads, and buying light bulbs that use less energy. Even simple things like using recycled paper or switching off the light when you leave a room can help. If we add up all these small changes made by everyone worldwide, they won’t be such small changes. They could be the changes that save our future.

Many Chinese students have studied English for approximately ten years, but most of them cannot even speak English correctly or fluently. In my opinion, there are several obstacles(障碍)that have caused this to happen. The main obstacle is fear! Another is the habit of mentally translating from Chinese to English and then to change these thoughts into spoken words and sentences. Many of these difficulties are caused by the way Chinese people study and learn the language.

We must learn to speak as a child does. When we are learning a second language we need to remember how we learned our native language. Learning to understand and speak a language is one of the first skills a child develops. How does a child learn the language? He listens for a time and then he tries to repeat the words. Parents give great praise for the smallest effort and slightest improvement. Therefore, the child develops courage and is excited about learning. It takes a long time before he knows anything about grammar, spelling or formal sentence structures.

As for language teachers, they should avoid criticism(批评)and be very encouraging and generous with praise. Criticism or pointing out faults too often causes students to lose self-confidence and develop a fear of speaking. The best way to motivate a student is using Praise.

The most important aspect of speaking is having self-esteem. Self-esteem is how you feel about yourself. When most Chinese people are asked how their English is, or they are told their English is, or very are told their English is very good, they immediately respond by saying, ''Oh my English is very poor. ''If you say this to yourself often enough, you will believe it. When someone compliments(称赞)you, just say ''thank you ''.

When a consumer finds that something he or she bought is faulty or in some other way does not live up to what the producer says for it, the first step is to present the warranty(保单),or any other records that might help, at the store of buying. In most cases, this action will produce results.

However, if it does not, there are various means the consumer may use to gain satisfaction. A simple and common method used by many consumers is to complain directly to the store manager. In general, the “higher up” the consumer takes his or her complaint, the faster he or she can expect it to be settled. In such a case, it is usually settled in the consumer's favour, taking it as true that he or she has a just right.

Consumers should complain in person whenever possible, but if they cannot get to the place of buying, it is acceptable to phone or write the complaint in a letter.

Complaining is usually most effective when it is done politely but firmly, and especially when the consumer can show clearly what is wrong with what was bought in question. If this cannot be done, the consumer will succeed best by presenting specific information as to what is wrong, rather than by making general statements. For example, “The left speaker does not work at all and the sound coming out of the right one is unclear” is better than “This stereo(立体音响) does not work.”.

The store manager may advise the consumer to write to the producer, if so, the consumer should do this, stating the complaint as politely and as firmly as possible. But if a polite complaint does not achieve the expected result, the consumer can go a step further. He or she can threaten to take the seller to court or report the seller to a public organization responsible for protecting consumers' rights.

In 1971, China’s first subway line in Beijing was formally put into operation. By December　 2017, there were 171 subway lines stretching over 5,083 km in 35 cities on the Chinese mainland. Currently, China has the longest urban railway network in the world, which is predicted to surpass 6000 km by 2020.

The rapid development of China’s urban railway system reflects the country’s growing economic strength. The system has experienced the fastest growth over the past 15 years due to the investment of wealth accumulated from the reform and opening up in urban infrastructure construction. An urban railway system is expensive to build, with one kilometer of subway costing approximately 700 million yuan ($110 million). A city without economic strength cannot develop such an expensive system.

The progress in urban railway construction technologies has also contributed to the fast expansion of the infrastructure. Subway construction involves building underground tunnels, laying rails, manufacturing trains and the operation and management of subways. It is a systematic project which not only covers traditional infrastructure building but also modem electronics and information technology. China s railway construction technologies are the best in the world, with Chinese subway trains now exported to developed countries including the United States.

The expansion of Chinese cities has made it necessary to develop urban railway systems. Since the start of the reform and opening up, a large number of people have migrated to cities and the number of private cars has increased dramatically, resulting in serious traffic congestion. Building subways has become an important way to solve this problem.

This year marks the 40th anniversary of the launch of China’s reform and opening up, and the rapid development of China’s urban railway system exemplifies the achievements made by the policy. As China furthers its opening up, it will continue to maintain steady and rapid economic growth and railway systems will be available in more and more cities.

Throughout history, music spread among people of different cultures. In today's technologic advanced society, however, people spread music online, sometimes without an artist's permission. This can lead to many problems, and music companies are now dealing with this practice. Sharing music online without permission is theft (盗窃).

Sharing music online prevents recording companies from making money from their efforts. They say that sharing music online has led to a huge drop in profits and sales over the past 10 years. People who find music for free online are not paying for CDs or every MP3 downloaded. To truly understand the influence of music piracy (盗版) on creators, we must understand how many people are involved in the recording process. For the sale of each album, profits must be shared between musicians, sound engineers, music producers, managers, advertisers, and the company selling the product. Many people believe sharing music only affects the recording artist, but the reality is that sharing hurts business for all companies involved.

There are many people who don't see the harm in sharing music online and even think they have the right to do it. One online blogger states that he originally paid for an entire CD and that he should be able to do with the material whatever he wants. While he may have legally paid for the music, he does not have the right to provide permission, which means people like the blogger are thieves.

Although we don't spread today's music the same way we did before, there's no doubt that people around the word love to share music. However, Internet piracy would prevent musicians from continuing producing albums for fear of theft. Therefore, if people want to continue listening to their favorite artists, they need to buy their music so that artists will make enough profits to continue their music careers.

In December 2018, The Guardian changed its wording-using ''global heating'' instead of ''global warming'' -after scientists found that Earth's temperature is set to rise from between 2.5C and 4.5C. There had been a goal to keep the rise within 2C. And on May 1, the UK parliament (议会) declared a ''climate emergency'', becoming the first parliament to do so.

It's true that ''global heating'' and ''climate emergency'' are – in terms of language – two simple phrases. But they send out plenty of messages.

If with ''global warming'' we're still inside our comfort zone of handling the situation, entering the state of ''global heating'' is like heading to a point where the delicate (微妙的) balance of nature is disturbed so much that there is no turning back. Everything will be changing: Coral will die, polar bears will lose their habitats completely, and extreme weathers like droughts and heavy storms will happen at a higher frequency. There is no denying that we're entering a ''climate emergency''.

''Decades ago when the science on the climate issue was first increasing, the impacts could be seen as an issue for future generations, '' but, as Katharine Mach, a Stanford University climate scientist, told The New York Times, now it's definitely our issue, ''a shift (变化) we all are living together''.

However, getting these messages through is far from enough. It depends on each and every one of us to find a solution – if there are any solutions left to find.

''We have no time to waste, '' said the UK's Labour leader Jeremy Corbyn, according to the BBC. Corbyn urged that ''we take rapid and dramatic action now''.

Indeed, language matters. But action matters even more.

Of the thousands of different kinds of animals that exist in the world man has learned to make friends with an enormous number. Some are pets，and offer him companionship; some give protection，and some do hard work which man cannot do for himself. Dogs，which serve man in all three capacities，are found in various species in all countries of the world. The Husky can live in the cold polar regions，and the Saluki is at home in the hottest parts of Central Africa. The people of certain countries are dependent for their very lives on the camel. In the West Indies the little donkey，strong and sure－footed，carrying heavy loads even in mountainous places，is a familiar sight.

Trained and tamed for many generations，domestic (驯养的)animals are not accustomed to wandering in search of food and shelter. They look to their masters to provide for their needs，and as long as these are supplied，they are content to do what their masters require.

All domestic animals need proper food. It must be suitable for them，enough in quantity，fresh and clean. Some people feed a pet dog or cat on odds and ends of table scraps (吃剩的东西)，and then wonder why the animal seems tired and dull. The quantity of food depends on the size of the animal and the amount of exercise it takes. Overfeeding is as bad as underfeeding. Containers for food and water must be washed regularly if the animal is to maintain good health.

Even well－cared for animals may sometimes fall ill. If this happens，the wise master seeks the best advice he can get. All sorts of medicines and treatments are available for sick animals，and in some countries organizations exist to provide them free or at a cheap price. Useful，friendly，hardworking animals deserve to have some time and money spent on their health.

In our modern world, when something wears out, we throw it away and buy a new one. The problem is that countries around the world have growing mountains of rubbish because people are throwing out more rubbish than ever before.

How do the society become a throwaway one? First of all, it is now easier to replace an object than to spend time and money repairing it. Thanks to modern manufacturing (制造业) and technology, companies are able to produce products quickly and inexpensively. Products are plentiful and cheap.

Another cause is our love of disposable (一次性的) products. As busy people, we are always looking for ways to save time and make our lives easier. Companies produce thousands of different kinds of disposable products: paper plates, plastic cups, and cameras, to name a few.

Our appetite for new products also contributes to the problem. We are addicted to buying new things. Advertisements persuade us that newer is better and that we will be happier with the latest products. The result is that we throw away useful possessions to make room for new ones.

All around the world, we can see the consequences of this throwaway lifestyle. Mountains of rubbish just keep getting bigger. To decrease the amount of rubbish and to protect the environment, more governments are requiring people to recycle materials. However, this is not enough to solve our problem.

Maybe there is another way out. We need to repair our possessions instead of throwing them away. We also need to rethink our attitudes towards spending. Repairing our possessions and changing our spending habits may be the best way to reduce the amount of rubbish and take care of our environment.
