Have you ever seen a solar panel(太阳能电池板)in your neighborhood? Solar panels take energy from the sun and turn it into electricity. Over the past ten years, the price of solar panels has gone down greatly. In many parts of the world, solar energy is now the cheapest form of electricity. More and more people have started using solar energy to power(给……供电)their homes.
However, solar panels also have their problems. They stop working at night and on rainy days. Is it possible to make them produce electricity all of the time?
Scientists at Suzhou University, China, have invented a new solar panel now. It can produce electricity not only from solar energy but also from falling rain. When a raindrop falls on the solar panel and then rolls(滚动)down, it creates friction(摩擦力)on the surface of the panel, which can then be turned into electricity.
Sun Baoquan is one of the inventors. “Our new invention can produce electricity in any weather during the day,” he says. “It can even provide electricity at night if there is rain.”
The solar panel, however, does not make much electricity from falling rain. So Sun Baoquan is still working hard to improve it. The scientist also wants to make solar panels more flexible, which are as soft as clothing.
The field of solar energy is developing fast. Scientists around the world have been improving solar panels. Some have been working on ways to join solar panels and wind power together. Some have been trying to use sunlight to produce liquid and gas fuels(液体和气体燃料).

On June 9th, 1870, Charles Dickens died at the age of 58. The next day, a headline in The New York Times read: “Death of the Great Novelist…Will Be Remembered by the People…”
The headline was not overstating (夸大) the popularity of Dickens. Even today, the British novelist is loved by readers all over the world. Dickens created some unforgettable characters. You must have heard of or even read some of his novels: Oliver Twist, A Christmas Carol and A Tale of Two Cities. A Tale of Two Cities has sold more than 200 million copies. Since 1897, there have been more than 300 film and TV adaptations(改编版本) of Dickens' works. A Christmas Carol alone has had nearly 50.
Natalie Mcknight is a literature professor(文学教投) who studies Dickens and his works. She explains why the novelist has remained so popular. One important reason, she says, is that Dickens wrote from his heart. He tried hard to produce emotional effects(情感效果) among his readers. In his works, he paid special attention to the "little man" at the bottom of society in the UK, which deeply mirrored the social reality at that time. A Christmas Carol, for example, was written to make every reader think about how they could make a difference to their society. People always enjoy works that make them laugh, cry and think. Many other 19th-century novelists wrote entertaining(娱乐的) works. However, few of them worked as hard as Dickens to touch the readers deeply.
Dickens wrote about situations and emotions that still interest people today. He used his pen to fight social inequality and gave voice to the poor. His works led to many important social changes. Readers always enjoy seeing poor people rise and succeed.

As a university student, I decided to learn German. For some reason I really liked the language, but I was not very good at learning it. The grammar _______ me a lot and even drove me crazy.

After two years of studies, I struggled (挣扎) to communicate in _______ German and signed up to study in Germany to complete my degree. It was the _______ term I would ever have.

I chose to study three courses—reading & writing, grammar and history. All were in German and difficult, but the history class was the worst.
