Most people know that Marie Curie was the first woman to win the Nobel Prize, and the first person to win it twice. However, few people know that she was also the mother of a Nobel Prize winner.

    Born in September, 1987, Irene Curie was the first of the Curies' two daughters. Along with nine other children the parents of whom were also famous scholars, Irene studied in their own school, and her mother was one of the teachers. She finished her high school education at the College of Sévigné in Paris.

    Irene entered the University of Paris in 1914 to prepare for a degree in mathematics and physics. When World War I began, Irene went to help her mother, who was using X-ray facilities (设备) to help save the lives of wounded soldiers. Irene continued the work by developing X-ray facilities in military hospitals in France and Belgium. Her services were recognised in the form of a Military's Medal by the French government.

    In 1918, Irene became her mother's assistant at the Curie Institute. In December 1924, Frederic Joliot joined the Institute, and Irene taught him the techniques required for his work. They soon fell in love and were married in 1926. Their daughter Helene was born in 1927 and their son Pierre five years later.

    Like her mother, Irene combined family and career. Like her mother, Irene was awarded a Nobel Prize, along with her husband, in 1935. Unfortunately, also like her mother, she developed leukemia because of her work with radioactivity (辐射能). Irene Joliot-Curie died from leukemia on March 17, 1956.

    People and animals often enjoy loving relationships with each other. When people adopt domesticated (家养的) animals into their families as pets, animals give humans the blessings of companionship and fun in return. In the wild, animals sometimes carry out dramatic rescues of people in dangerous situations, miraculously (奇迹般地) sensing human needs and jumping in without fear to help.

    In 2000, a 6-year-old boy unified Elian Gonzalez left Cuba on a boat bound for Florida in the United States, but the boat sank and everyone aboard drowned except Elian and two adults. Elian and the other two survivors held onto inner tube for 48 hours to try to stay afloat in the sea. After a while, however, Elian began to lose strength, slipping under the water and then grabbing the tube again as he fought to stay alive.

    A small group of dolphins noticed Elian struggling and swan over to him to help. The dolphins formed a circle around the inner tube and took turns using their noses to lift Elian until fishermen working in the area discovered and rescued Elian and the two adults who floated nearby. The fishermen reported that, when they discovered Elian, he was repeating a prayer that his mother had taught him before drowning, asking guardian angels to protect him.

    Miraculously, the dolphins knew that a child would need more help than adults, so they focused on Elian — and they figured out exactly what needed to be done and cooperated to carry out that plan successfully. They made it!

    I recently posted a picture on Facebook from the movie Mad Max, a film where two groups race through the desert in steam punk vehicles, and wrote, “Actual picture of my way to work today.” It was meant to be a joke because of the sandstorms in Beijing, but one of my friends from back home thought it was real.

    I couldn't imagine how they could think that is actually what China is like. China has so many more conveniences and advantages than the West, and many of my friends agree. “I don't know how I will be able to deal when I go back home,” said a friend who is about to end her gap year in Beijing. “I've become so spoiled in China.

    China seems to be leading the way in innovation and convenience for daily life. Back home I could never shop, pull out my phone and scan a QR code to pay.

    There have been rumors of starting bike sharing in my hometown for years with little success while bike sharing suddenly appeared in Beijing overnight. I just step outside and scan a code, and I am on my way.

    Going out to eat with a group of friends back home was troublesome for both the group and the servers. Splitting checks and swiping (刷) 10 different cards or making change for each person in the group can be a pain. But with China's WeChat, you can quickly send your friends your part of the bill.

The list goes on...

    When I first arrived in Beijing, I was dead set on leaving in a month. That month has come and gone. Now, when someone asks me when I'm coming back, I think to myself, “Who knows?”

    While my friends think I'm riding through the desert on a motorbike, I am actually taking a “Didi” for what is the equivalent of $5 in the US.

    With all the conveniences and technology here, I may never want too go back.

    If you love to read, and if you love social networking, you should check out Goodreads. Goodreads allows you to write reviews（评论）for everything you've ever read. You can see and comment on your friends' reading progress, as well as create or find a book club group page in your area.

    Goodreads is simple to use. When you sign up here for an account（帐户）, you will be able to find your friends by their email addresses or other accounts. Once you have some friends, every time you log in（登录）, you will see a timeline of their updates. You can see when they've added a book to a list, or when they've finished or reviewed a book. As soon as you have an account, you can also start looking for books you've read or that you want to read. Once you finish reading a book, you can go to the book page and review it.

    Finding your next book has never been easier. Now, not only can you search for books you know you want to read and add them to your “to read” list, but you can also easily see what your friends have recently read.

    If you are looking for a book club that meets in your area, you can search for that on Goodreads, too. Similarly, if you want to create your own book club, you can do that easily: just start a new group on Goodreads and update the page to show what books you're reading.

    Many people don't consider their breakfast without a glass of milk. Right now, cows, buffalos, goats and sheep provide most of the world's milk. But soon, people could get milk from roaches(蟑螂).

    That isn't as crazy as it might sound. New research shows this “milk” is super-nutritious. What's more, some scientists have already begun referring to a lot of insects as source of milk.

    In 2004, Subramanian Ramaswamy started studying milk crystals found inside the roach. At the time, he was teaching biochemistry at the University of Iowa City.

    To learn more about the milk crystal from roaches, the scientists used X-rays to look at the atoms in it. The data basically revealed the chemical recipe of the roach crystal. They showed that roach milk is a “complete food”. It contains sugar with a fatty acid stuck to it. Fatty acids are the building blocks of fats. The protein in the milk is also full of essential amino(氨基的) acids, which are the building blocks of proteins. Since our bodies can't produce the “essential” ones, we need to get them from our food. And so do baby roaches.

    Barbara Stay, a biologist at Iowa University, also worked on the new study. She says the new data show that the roach milk is “three times more nutritious than cow's milk and four times more nutritious than buffalo's milk”.

    Ramaswamy would like to see roach milk turned into a protein supplement to feed hungry people. But not everyone is confident that it can be done.

    Marcel Dicke studies insects as a potential source of human food at Wageningen University in the Netherlands. Dicke says this is a “sound study”. However, in his opinion, “Extracting(提取) milk from roaches can only likely be done in a destructive way with only small quantities”. That means you'd have to raise and kill many bugs to get even tiny quantities of the milk.

In the Ming Dynasty, a Chinese man {#blank#}1{#/blank#} (name) Wan Hu made the world's first rocket(火箭), {#blank#}2{#/blank#} unluckily he lost his life with it. It was not until April 24, 1970 {#blank#}3{#/blank#} China launched(发射) its first man-made satellite Dongfanghong-1 successfully. To celebrate the first big success in the country's space {#blank#}4{#/blank#} ( develop), we now make April 24 China's Space Day.

China also announces new plans {#blank#}5{#/blank#} ( make) a space station and go to Mars and further space. It will finish building its space station around 2022. According to China's top space scientist Zhou Jianping, at that time, {#blank#}6{#/blank#} (become) an astronaut will be a normal job. More astronauts are needed than ever before. They need to be able to finish difficult {#blank#}7{#/blank#} (task).

By now, China has been choosing astronauts {#blank#}8{#/blank#} (main) from pilots like Yang Liwei. In the future, astronauts {#blank#}9{#/blank#} ( pick ) from engineers, doctors and space technology experts. Another plan is about Mars. In order to explore Mars, China sent {#blank#}10{#/blank#} spacecraft(航天器), whose name is Tianwen-1, to Mars on July 23, 2020. It will land on Mars and even bring back things from Mars.
