    （I）It was a surprising announcement: SpaceX, a private company（私人公司）, said it would fly two people to the moon next year (2019). This has not been attempted since NASA's Apollo moon landings about 45 years ago. In the news conference, Elon Musk. SpaceX founder said two people have already paid SpaceX a “wonderful” amount of money to send them on a weeklong flight just beyond the moon.

    （II）Exercise reduces the risks of dying from all causes, including cancer and heart disease. But many people who work all week have little time for exercise. They try to take exercise or do chores to increase their heart rates over the weekend. A new study suggests that it is healthy to do that, which can reduce their risk of cancer and cardiovascular（心血管疾病）disease.

    （III）Scientists in London have found a possible way to solve the problem of plastic bottle waste. They have made a water bottle you can eat. The product is called Ooho, made of seaweed, a plant that grows in the ocean. Oohos are tasteless and look like bubbles or balls. They can hold water or any other liquid（液体）inside. When people drink Oohos, the outside bursts in the mouth and can be eaten. Even if you throw it away, it will degrade in about four weeks. It is good for the environment.

    Children moving from primary to secondary school are ill-equipped to deal with the impact of social media, as it is playing an increasingly important role in their lives and exposing them to significant emotional risk, according to a recent report by the Office of the Children's Commissioner for England.

    The report shows that many children in year 7 -- the first year of secondary school, when almost all students will have a phone and be active on social media -- feel under pressure to be constantly connected.

    They worry about their online image, particularly when they start to follow celebrities on Instagram and other platforms. They are also concerned about “sharenting” -- when parents post pictures of them on social media without their permission – and worry that their parents won't listen if they ask them to take pictures down.

    The report, which was created with data from focus group interviews with 8 to 12-year-olds, says that although most social media sites have an official age limit of 13, an estimated 75 percent of 10 to 12-year-olds have a social media account.

    Some children are almost addicted to “likes”, the report says. Aaron, an 11-year-old in year 7, told researchers, “If I got 150 likes, I'd be like, that's pretty cool, it means they like you.” Some children described feeling inferior(差的) to those they follow on social media. Aimee, also 11, said, “You might compare yourself because you're not very pretty compared to them.”

    Children's Commissioner for England Anne Longfield is calling on parents and teachers to do more to prepare children for the emotional impact of social media as they get older. She wants to see the introduction of compulsory digital literacy and online resilience (适应力) lessons for students in year 6 and 7.

    “It is also clear that social media companies are still not doing enough to stop under-13s using their platforms in the first place,” Longfield said.

    “Just because a child has learned the safety messages at primary school does not mean they are prepared for all the challenges that social media will present,” Longfield said.

    “It means a bigger role for schools in making sure children are prepared for the emotional demands of social media. And it means social media companies need to take more responsibility,” Longfield said.

    Everything has its root. “Holiday”, is no exception. The origin of “holiday” is easy to see, coming from “holy day”, a day of particular religious significance, often celebrating the life of a saint (圣徒), during which no work was to be done. As far back as the 11th century, “holidays”, especially the major feast days, were times of “celebration and amusement”, as the Oxford English Dictionary puts it.

    The number of holidays steadily increased during the Middle Ages, until a medieval Englishman would have had the luxury of 40 to 50 days a year off work, depending on where he lived, in addition to a free day on Sundays.

    During the Reformation, Henry VIII abolished most of the holidays partly because of the Protestant (新教徒的) suspicion of saints, but more practically, because, according to historian Eamon Duffy, “A large number of holidays were making the people poor by limiting agriculture.” The people took a different view and organized a protest march—the Pilgrimage of Grace—partly to protect their days off.

    Though at first the religious and festive senses of holiday were combined, the word gradually came to be used for any kind of relaxing break from work. As the word was drawing away from a religious society, the number of authorized holidays was reduced, until by 1834 most workers had only four official days off a year, in addition to Sundays. Many factory workers amplified this time by staying home on “Saint Monday” to recover from what they had gotten up to the day before.

    By the late 19th century, employers were compromising and offering half-day Saturdays, the beginning of the “weekend”, a term first used in 1879. In 1908, an innovative mill in New England gave its employees all of Saturday off, and the practice of their getting the whole Saturday off spread widely during the Great Depression as a way to keep employment up. It took 400 years, but finally workers could enjoy as many holidays as they had in the 15th century.

There are so many choices when you go shopping. You have to check the sell — by dates so that you know how long you can store and use the food you are purchasing.

But do you know that the best sell — by dates on food packaging don't really tell you if the food is safe to eat. The food may not last as long as it says if it isn't stored correctly at any point of the distribution chain. Now there is food packaging that can detect and change colors if the food has gone bad.

Each American wastes 103 pounds of spoiled food out of the refrigerator every year. The new smart packaging from Primitives Biodesign—a new company that operates out of a lab at Indibio, a biotech accelerator in San Francisco-can help to reduce this huge waste of food.

The basic material that doesn't contain sensing material is made from algae and can block oxygen more effectively than regular film, so the food stays fresher for a longer time. Since it is made from a natural substance, it can also break down in nature.

Making the film smart is the thorny part. Luckily, the team managed to use a process that is like the way nature responds to changes in the environment. The mechanism responds like the way flowers emit compounds to change colors.

"It could be supplement packaging that indicate when it's been tampered with by changing color to tell you that it's no ledger safe," says Kan. She explained that the new packaging can be used on food products to fell if the food has turned bad before someone has to smell or taste it.

The company has proven in lab tests that the technology works and now they are working on how to develop commercial uses for it. The added safety features will come out later. Helping to control food waste in products like meat or cheese which have high greenhouse gas emissions will also help to reduce climate change.
