Well, to pick up where we left off last time. I’m certain that you know all too well the dangers hiding on the World Wide Web. And whether it’s for schoolwork, entertainment, or just socializing with friends, the Internet will surely be a major part of your child’s life. So, it’s important to secure their online stays.
It’s not the easiest thing, but keeping open lines of communication is primary. Let them know they can share their online activities with you. Talk to them about their online presence as early as possible, ideally before they begin to use email, social media, or a smartphone. Discuss what they find interesting online and learning from them about popular websites and apps; this will create understanding and allow you to identify potential risks.
Next, monitor without spying. Most kids learn to understand boundaries, like respecting others’ personal space, or not opening the cookie jar without asking. Internet use is no different. It’s helpful for kids to have ground rules as to which websites they can visit,which apps they can use, and what they can share online. Remind them that if they feel uneasy with anything that occurs online, they need to alert an adult immediately.
How you handle your kids’ internet usage will depend in large part on their age. There are sites and browsing tools meant for younger kids, such as YouTube Kids,which aims to provide a safe online experience for children.Older kids may be allowed more freedom since they want to network and need to use the internet for information-gathering. But you can set boundaries that feel right for you. Just limit access appropriately.
Allowing your children to make good decisions online teaches them responsibility, shows that you trust them, and reminds them that rules may be tightened if they disobey them. Stay tuned.

It is certainly difficult to make money. But should money be difficult to give away? In The Gilded Age, industrialists such as Andrew Carnegie and John D. Rockefeller worried about waste and misuse; Carnegie wrote in 1889 that $950 of every $1,000 that went to charity was “unwisely spent”.
Fortunately, a new generation of donors is once again shaking up the world of big philanthropy (慈善事业). Leading the mission is MacKenzie Scott, who simplified the process of giving and is donating billions of dollars a year with few conditions. This “no-strings giving” is changing mega-donors’ long-held assumptions.
One is the recognition that philanthropists do not have to do everything themselves.
Another lesson from the no-strings crowd is that philanthropists can trust recipients to put money to good use once the proper due diligence is in place. That means analyzing a nonprofit organization’s annual reports and interviewing its leaders and other funders.
A.It offers lessons for those struggling to get money out of the door. |
B.In addition to that, her charity work is too numerous to mention. |
C.However, this idea that charities’ money is wasted has been proven wrong by evidence. |
D.Mega-donors no longer need to endure the trouble of setting up a foundation and hiring staff. |
E.Two decades on, however, it’s become clear that all this paperwork puts the brakes on giving. |
F.Around the turn of the millennium donors looked to data and rules as a way to stop waste. |
The endangered pandas in the Qinling Mountains might face a new threat: the loss of their food, bamboo, which makes up 99% of their meals.
Adult pandas spend most part of the day eating bamboo and have to take in at least 40 pounds a day to stay healthy. However, a new study published in Nature Climate Change warned that they may soon find their food gone because most of the bamboo in the Qinling Mountains might disappear by the end of the century as a result of rising temperature worldwide.
A team made up of researchers from Michigan State University and the Chinese Academy of Sciences has studied the effects of climate change on the bamboo in the Qinling Mountains. They have found that bamboo is very sensitive to climate changes. “80% to 100% of the bamboo would be gone if the average temperature rises 3.5 degrees worldwide by the end of the century,” said Liu Jianguo, one of the report’s authors.
He added, “This is how much the temperature would rise by 2100 even if all countries will keep their promises in the Paris Agreement. But you know what is happening all around the world.”
In recent years, China has been trying its best to protect the endangered pandas by setting up more and bigger natural reserves.
“But it is far from enough and the endangered pandas need cooperation from the rest of the world, because their future is not just in the hands of the Chinese,” said Shirley Martin from the World Wildlife Fund but not a member of the team.
The Qinling Mountains, in the southwest of China, are home to about 260 pandas. That is about 13% of China’s wild panda population. In addition, about 375 are living in research centers and zoos in China.

“The lift becomes this interesting social space where behaviors are sort of odd (奇怪的),” Gray told the BBC. “They (elevators) are socially very interesting but often very awkward places.”
We walk in and usually turn around to face the door. If someone else comes in, we may have to move. And here, according to Gray, liftusers unthinkingly go through a set pattern of movements. He told the BBC what he had observed.
He explained that when you are the only one inside a lift, you can do whatever you want – it’s your own little box.
If there are two of you, you go into different corners, standing diagonally (对角线地) across from each other to create distance.
When a third person enters, you will unconsciously form a triangle. And when there is a fourth person it becomes a square, with someone in every corner. A fifth person is probably going to have to stand in the middle.
Newcomers to the lift will need to size up the situation when the doors slide open and then act decisively. Once in, for most people the rule is simple – look down, or look at your phone.
Why are we so awkward in lifts?
“You don’t have enough space,” Professor Babette Renneberg, a clinical psychologist at the Free University of Berlin, told the BBC. “Usually when we meet other people we have about an arm’s length of distance between us. And that’s not possible in most elevators.”
In such a small, enclosed space it becomes very important to act in a way that cannot be understood as threatening or odd. “The easiest way to do this is to avoid eye contact,” she said.
【小题1】The main purpose of the article is to _____.
A.remind us to enjoy ourselves in the elevator |
B.analyze what makes people feel awkward in an elevator |
C.share an interesting but awkward elevator ride |
D.tell us some unwritten rules of elevator behaviors |
