With more and more cars on the road, traffic jams are inevitable(不可避免的）. Traffic jams can lead to increased accidents as there are more cars. It's impossible to avoid traffic jams altogether.{#blank#}1{#/blank#}

    Check for traffic jams before you leave.

    You can listen to the radio for traffic news, or check on the Internet to get up-to-minute information on traffic. If the route you want to take is heavy with traffic, you can choose another.

    Look for a different route all the time.

    Most traffic jams happen on busy roads.{#blank#}2{#/blank#}Although the distance you may have to travel is further, it can work out quicker.

    Set your car radio to receive traffic bulletins.

    Many new car stereo systems (汽车音响系统) are equipped with a radio system by which you can hear the traffic channel.{#blank#}3{#/blank#}

    Recently I started discovering one thing which amazes me so much: how perfect everything is in the world we are living in! Just look, all day long we are busy working and just when we get tired, the night comes in, so we may sleep and relax. One day we may enjoy the bright sun and another day, when we get tired of the sun, the rain pours down.

    A few months ago I was so happy with my life. Later, I got tired from the happiness. I wished I would have some trial to strengthen my character and learn something new about life. I got what I wanted. Shortly after I got severe angina (心绞痛), so I had to stay home for several weeks. During this period I had time to rethink my life and discover myself. The lessons were terrific, but I felt grateful for this time.

    Another example: I have a friend, who primarily thinks about having fun. Once I thought why we get along well with each other and what in me attracts her. A couple of days ago I found the answer. I like calmness and silence. She likes noise and agitation (热闹). We attract each other just to balance ourselves, in other words, to give some drive to me and some calmness to her!

    So remember that the universe is so wise that it will try to balance you. As for me, this is perfect because extremes create suffering: too much food – too little food, too cold – too hot, too much fun – too little fun.

    A recent university study found that current electric cars could be used for 87% of daily car journeys in the US. That figure could rise to 98% by 2020.

One hurdle to the widespread adoption of electric cars has been “range anxiety” —drivers' concerns about running out of petrol on a journey. While petrol stations are conveniently located across national road systems, the necessary network of electric charging stations is still being developed. In fact, charging points are becoming increasingly common throughout the USA.

    Attitudes towards electric vehicles have changed quite considerably over the last few years. Not that long ago, electric cars met with doubt, and their high price drove customers away. Thanks to improvements in battery capacity(电池容量), recharging times, performance and price, the current generation of electric cars is starting to persuade critics.

    As well as progress on the road, electric vehicles are taking to the sea and sky. Electric boats are among the oldest electric vehicles, having enjoyed several decades of popularity from the late 19th to the early 20th century before petrol-powered outboard motors took over. Now, the global drive for renewable energy sources is bringing electric boats back. Steps towards electric planes are also being made, with Airbus and NASA among the organizations developing and testing battery-powered planes. The experiments could soon make electric flight a reality.

    Electric vehicles do not produce any emissions(排放物). Were the US to act on the study's findings and replace 87 percent of its cars with electric vehicles, it would reduce the national demand for petrol by 61 per cent. However, because of the production processes and the generation of electricity required to charge these vehicles, they cannot claim to be completely emission-free. Even so, as many countries continue to increase their use of renewable energy sources, electric vehicles will become even cleaner.

    At schools across the United States, students often sit down to cafeteria lunches made from processed foods that are high in fat, sodium, and sugar. But kids at Public School(P. S. )216 in Brooklyn have a different dining experience. Principal Donna Neglia reports that her students love eating fresh fruits and vegetables.

    P. S. 216 participated in the Edible Schoolyard Project, a nonprofit program founded by Chef Alice Waters in 1995. The program that Waters created helps public schools across the country start on-site gardens and weave principles of healthy eating into the curriculum. Students grow and maintain crops, harvesting the fruits and vegetables for cafeteria meals.

    Waters expressed her passion for the principles of the farm-to-table movement. She advised schools to connect with the farmers in their area and change their buying practices when planning meals for students.

    Waters has long been inspiring people to care about where their food comes from. In 1993, she put forward the idea of a White House vegetable garden. It was not until 2009 that Michelle Obama started the garden in the backyard of the White House. She and members of the kitchen staff spent hours tending to the garden, often with help from local school children.

    “That gave people a sense that she cared about children and cared about where our food comes from,” Waters said, praising the former First Lady's concern for young people's health. “We are just building this movement, and it is very exciting. ”

    “Through the Edible Schoolyard Project, students also learn about the benefits of healthy eating in the classroom.” Neglia said. “P. S. 216 is teaching kids about careers in the food industry—such as farming and agriculture, nutrition, food safety, and the restaurant business.”

    Similar classes are taking place around the country. So far, the Edible Schoolyard Project has reached more than 1 million students in more than 367 schools. “I'm thinking about the future of the planet,” Waters said. “I'm doing this for our generation.”

    A team of international scientists is due to set off for the world's biggest iceberg in a mission aiming to answer fundamental questions about the impact of climate change in the polar regions. The scientists, led by the British Antarctic Survey (BAS), are trying to reach a newly revealed ecosystem that had been hidden for 120,000 years below the Larsen C ice shelf.

    Last year, part of the Larsen C ice shelf calved (崩解) away, forming a huge iceberg-A68—which is four times bigger than London, and revealing life beneath for the first time. Now scientists say it is a race against time to explore these new ecosystems before they are transformed to the light. Marine biologist Dr Katrin Linse from the BAS is leading the mission.

    "The calving of A68 provides us with a unique opportunity to study marine life as it responds to a huge environment change," she said. "It is important that we get there quickly before the undersea environment changes as sunlight enters the water."

    Professor David Vaughan, science director at the BAs, said, "We need to be bold (大胆的) on this one. Larsen C is a long way south and there's lots of sea ice in the area, but this is important science, so we will try our best to get the team where they need to be. He said climate change had already affected the sea around Antarctica and is warming some coastal waters. "Future warming may make some habitats warm. Where these habitats support unique species that are adapted to love the cold and not the warm, those species are going to either move or die."

    There is growing concern about the possible impact of climate change in the Antarctic. Earlier this month, a report revealed that melting ice sheets in Greenland and Antarctica are speeding up the already fast pace of the sea level rise. The research, published by the National Academies of Science, Engineering and Medicine, said, "At the current rate, the world's ocean will be, on average, at least 60cm higher by the end of the century." However, it found that the process is accelerating, and more than three quarters of the acceleration since 1993 is due to melting ice sheets in Greenland and Antarctica, the study shows.

The urgency and importance of Covid-19 over (he past year have driven almost everything else from most leaders5 minds. But since the vaccine is kicking in, Britain's government is once again beginning to think about the things that will matter later. Next week, it is expected to publish a 'plan for growth" to boost productivity, with innovation at its centre.

The world may be on the point of a technological boom with life sciences, at which Britain excels. Innovation is crucial to productivity, but on this front Britain's performance has lagged behind its competitors' in recent years. Its low spending on Research and Development (R&D) argues for a boost. Those who attributed the financial failure in the 1970s to the insufficiency of research funds may regard this as a threat to economic growth. Promoting innovation can quickly (um into an exercise in picking winners - or, as is more often the case, losers.

A second danger is that policy agendas get mixed up. The government has promised to "level up" poorer areas of the country, so deprived towns arc campaigning for more money for their universities. But trying to boost innovation by sending money to weak institutions is likely to make our leading universities lose their advantages, thus producing average ideas that could have been remarkable. Britain's research-funding system has always been elitist(精英主义的). It should stay that way.

The government's first move in boosting innovation was the announcement of a plan for an Advanced Research and Invention Agency (ARIA). ARlA's purpose is to fund high-risk, high-reward research. But money is not all that mailers. The successful translation of life science research into treatments during the pandemic suggests some inexpensive measures that can also make a difference.

One is to speed up governmental processes. The rapidity with which Britain's medical regulator moved during the pandemic is one reason why the vaccine rollout is racing through the population. Urgency is not unique lo pandemics. Getting things done quickly can make an investment worthwhile and determine where a businessman chooses as a base.

Another useful measure the government should use is its unique ability to overcome barriers. At the beginning of the pandemic. Covid-19 researchers were unable to gain access to different strands of health service data. The government eased restrictions on existing data and allowed researchers to ask people who had tested positive tor Covid-19 to join trials. Both were crucial to the effort.

A last principle is the value of connections between the government and the private sector. Kate Bingham, a venture capitalist who led the vaccine-purchase effort, understood how to deal with drug companies. Many of the civil servants working with her had commercial experience. The governments closeness to business during the pandemic has been criticized. But without it, the vaccine effort would not have succeeded.

Innovation took human beings from caves to computers. Good education, a welcoming immigration policy and a friendly business environment will do most to tend it. But a new sensible principles can help keep the flame burning.
