InEngland, people often talk about the weather because you can experience fourseasons in one day. In the morning the weather is warm just like in spring. Anhour1 black clouds come, and then it rains hard. Theweather gets2 cold. In the late afternoon the sky will beclear, the sun will begin to shine and it will be summer at this time of a day.

    InEngland, you can also have summer in winter,3 have winter in summer. So in4 you can swim sometimes, and in summersometimes you should wear warm clothes.

    When yougo to England, you will see some English people take umbrellas or rain-coatswith them on the5 morning,but you shouldn't laugh at them. If you don't take an umbrella or a raincoat,you will regret later in the day.

Scientists have made a "breakthrough" in handling nuclear fusion（核聚变）. The US Department of Energy officially announced the milestone in fusion energy research.

For the first time, researchers created a nuclear fusion reaction that produced more energy than they put into the process. The experiment, conducted at Lawrence Livermore National Laboratory in California, generated 3.15 megajoules of energy, more than the 2.05 megajoules put into creating it.

Nuclear fusion works by forcing together two atoms—most often hydrogen—to make a heavier one—like helium（氦）. This explosive process releases massive amounts of energy, the Department of Energy explains. Fusion is the opposite of fission（裂变）, the reaction that powers nuclear reactors used commercially today.

Fusion occurs naturally in the heart of the Sun and the stars, providing these cosmic（宇宙的） objects with fuel. Since the 1950s, scientists have been trying to reproduce it on Earth inorder to make use of the so-called clean, cheap, and almost limitless electricity. According to the International Atomic Energy Agency, fusion generates four times more energy per kilogram than the fission used to power nuclear plants, and nearly 4 million times more energy than burning oil or coal. What's more, unlike fossil fuels, fusion doesn't release carbon dioxide—the greenhouse gas that's the main driver of climate change — into the atmosphere. And unlike nuclear fission, fusion doesn't create long-lived radioactive waste, according to the Department of Energy. But so far, nuclear fusion hasn't solved our energy problems on a grand scale.

The recent announcement is a huge step forward in nuclear fusion energy, but applying the technology at commercial scale is likely still years away. Chanda Prescod Weinstein, a theoretical physicist, pointed out that the process the Department of Energy uses requires tritium（氚）, a rare and radioactive isotope（同位素） of hydrogen."It may yet convey important information that is ultimately transformative. We don't know yet,"Prescod Weinstein tweeted. Investors, including Amazon founder Jeff Bezos, have poured billions into the clean energy field trying to make fusion commercially workable, and the recent announcement is likely to continue that trend.

The four great inventions of ancient China are China's outstanding contributions to the whole world, and have had a great impact on world's scientific and cultural exchanges.

Different people may have different hobbies. I think hobbies can help us relax and learn more things. I have four good friends. They all have their hobbies. 

Whether it's changing jobs, taking care of a sick parent, or moving to a new place, disruptions(混乱) in life can make it hard to maintain moment-by-moment focus and well-being (健康). Long-term goals remain important, but long-term focus can be hard. Daily or weekly habits supporting your long-term goals can keep you on track even when it's hard to think ahead.

{#blank#}1{#/blank#}

 The first is personal reflection(反思). This can mean keeping diaries, documenting the funny things our friends say, and recording what we are thankful for a few times per week. {#blank#}2{#/blank#}

 Second, we need time for professional reflection. For example, you may sit down on a Sunday night and write down the most important to-dos in the coming week. {#blank#}3{#/blank#}Instead, it directs your focus to what's most important. Simple, daily or weekly reflection case make a meaningful difference in productivity and focus.

A third area is building and maintaining relationships. It's important to manage our relationships well. For us, right now, the primary relationships are with our parents and teachers. {#blank#}4{#/blank#}These sound like small things, but they matter a lot.

 Finally, we all need to form good habits that encourage physical and mental health. Studies show that people who get at least two days of exercise per week are happier. {#blank#}5{#/blank#}
