One morning, Ann's neighbor Tracy found a lost dog wandering around the local elementary school. She asked Ann if she could keep an eye on the dog. Ann said that she could watch it only for the day.

    Tracy took photos of the dog and printed off 400 FOUND fliers（传单）, and put them in mailboxes. Meanwhile, Ann went to the dollar store and bought some pet supplies, warning her two sons not to fall in love with the dog. At the time, Ann's son Thomas was 10 years old, and Jack, who was recovering from a heart operation, was 21 years old.

    Four days later Ann was still looking after the dog, whom they had started to call Riley. When she arrived home from work, the dog threw itself against the screen door and barked madly at her. As soon as she opened the door, Riley dashed into the boys' room where Ann found Jack suffering from a heart attack. Riley ran over to Jack, but as soon as Ann bent over to help him the dog went silent.

     “If it hadn't come to get me, the doctor said Jack would have died,” Ann reported to a local newspaper. At this point, no one had called to claim the dog, so Ann decided to keep it.

    The next morning Tracy got a call. A man named Peter recognized his lost dog and called the number on the flier. Tracy started crying, and told him, “That dog saved my friend's son.”

    Peter drove to Ann's house to pick up his dog, and saw Thomas and Jack crying in the window. After a few moments Peter said, “Maybe Odie was supposed to find you, maybe you should keep it.”

    There are many different voices on charity donations recently. Chen TianQiao, one of the Chinese billionaires, gave away $115 million to the California Institute of Technology (Caltech) to help promote brain research. Chen has been interested in the brain research, believing it can advance the industries of artificial intelligence and virtual reality. However, this huge donation has caused heated discussion among Chinese scholars and internet users.

    Many criticized him for giving money to a foreign university rather than domestic institutes for brain research, which are developing fast and are catching up with the US in just a few years. RaoYi, a biologist at Peking University, even said the donation was a typical mistake.

    Others, however, support his choice. They believe Caltech is a more reasonable choice compared with Chinese research Institutes. Caltech has a long history and has taken a leading position in biology, and therefore it produces more efficient results. What's more, the results of the research will benefit not only the Americans, but also the rest of the world.

    A similar controversial（有争议的）case started two years ago when Pan ShiYi, chairman of SOHO China, donated $15 million to Harvard University to help disadvantaged Chinese Students.

    Many believe that China is still far behind in management and use of donated money, and that as a result, Chinese donators are looking abroad. In comparison, Western countries like the US, which have a long history of donating money, have well-developed systems that use money efficiently. They can also provide full access for donors who want to track the use of the money. To get more donations, Chinese universities should be braver and more honest. They need self-reflection rather than envy.

    English is the most widely used language in the history of our planet. One in every seven human beings can speak it. More than half of the world's books and three quarters of international mail are in English. Of all languages, English has the largest vocabulary — perhaps as many as two million words.

    However, let's face it: English is a crazy language. There is no egg in an eggplant, neither pine nor apple in a pineapple and no ham in a hamburger. Sweet-meats are candy, while sweetbreads, which aren't sweet, are meat.

    We take English for granted. But when we explore its paradoes (探索它的矛盾), we find that quicksand can work slowly, boxing rings are square, public bathrooms have no baths in them.

    And why is it that a writer writes, but fingers don't fing, grocers don't groce, and hammers don't ham? If the plural of tooth is teeth, should't the plural of booth be beeth? One goose, two geese — so one moose, two meese?

    How can a slim chance and a fat chance be the same, while a wise man and a wise guy are opposites? How can overlook and oversee be opposites, while quite a lot and quite a few are alike? How can the weather be hot as hell one day and cold as hell the next?

    English was invented by people, not computers, and it reflects the creativity of human beings. That's why, when stars are out, they are visible (能看见的); but when the lights are out, they are invisible. And why, when I wind up my watch, I start it; but when I wind up this essay, I end it.

    July is a month of fun-filled activities for kids and teens as long as you know where to find them. When you want some fun activities for July, consider these ideas happening in this month.

    Taking on the task of producing a short movie might seem like an impossible feat, but if you can assemble a good team and if you break down each stage of production into small blocks of tasks, you'll come to realize that producing a small-scale movie isn't too bad. Just follow these steps and you'll be on your way to Kevin Smith-like fame in no time.

    Assemble a production crew. If you run out of friends or people you can get to work for screen credit, offer people “points”, which is a percentage of the movie profits.

    Get a director of photography. You need someone who knows a lot about films cameras to make the movie come out right. Local film schools are the best place to find them.

    Assemble the props and costumes. Costume shops and local theater groups can definitely help you here. But you can also borrow from friends and family or check out thrift stores for bargains.

    Choose filming locations. Make sure you have permission from the owners of the property you choose to film on.

    Get the film processed. Find the right processor with the help of your director of photography. You may need to send the film to Los Angeles for this.

    Edit the film. You need to find someone who can transfer your film to video and arrange the completed scenes in the right order. You can likely find one in the same place as your director of photography,

    Obviously, this is just a basic overview—the thing about producing a short independent movie is that the whole process is unpredictable. You can only set yourself up for the basics, but as long as you know things will go wrong every day, at least you'll be prepared to deal with the difficulties.

Foldable phones are once again facing questions about their durability(耐久性).The Galaxy Z Flip and the Motorola Razr are now both available to buy in the US-but early reports suggest the screens are easily damaged.

One media published photos of two layers of the Razr's display separating, affecting the touch screen. The Galaxy flip, meanwhile, boasts(自夸)a "flexible glass" display—but tests appear to show it scratching(刮擦)as easily as plastic.

In a statement, Samsung said the display had a protective layer, and had undergone extensive testing. "While the display does bend, it should be handled with care, "it said.

The Z Flip's "pretty thin glass" is one of Samsung's primary marketing messages for the new phone. But a durability test conducted by popular Zack Nelson, a regular buyer, suggested it was no more durable than soft plastic screen, and could even be dented(痕)by fingernail.

Nelson said Samsung's screen scratched exactly how plastic screen would react. "I don't know what material this is, but Samsung definitely shouldn't be calling it glass," he said. He found that the screen of the Motorola Razr scratched as easily but it is not marketed as "glass".

The Motorola Razr was put on sale 13 days ago in the US, but Raymond Wong, an editor says the flexible screen on his handset has already broken. The upper layer of the Razr's screen separated from the bottom, creating "a giant horizontal air bubble" for no apparent reason. He wrote that the fault appeared after 45-minute train ride during which the phone was in his pocket. The screen was completely warped from hinge-to-hinge with the top layer raised like a poorly applied screen protector. But Mr. Wong said that apart from the visual problem, the damage has affected the responsiveness of the touchscreen.
