【推荐2】The physical memory dump error is a big problem that affects even the most advanced computer systems．Although it's quite a rare error, it's one of the most stopping what you're doing and restarting your computer—making you lose all your unsaved data．This is a big problem, but there is actually a very easy way to fix it．
There are two reasons why the physical memory dump happens．The first is pretty simple and is to do with the "hardware", and if any of these pieces are not fit for your system, it will cause the physical memory dump．So, if you've recently added any hardware to your PC, then take that out and see if it works．
The other reason is your system, the "registry"．The registry is a big database that operates in the background of Windows, storing all sorts of settings and information about your PC．The problem with the registry is that since it has so many important files inside, it's constantly got hundreds of files open every time you use your PC．And because there are so many files to open at once, Windows is constantly getting confused, leading it to save many of these files in the wrong way．These files go wrong when saved wrongly, making them difficult for your computer to read．However, if it can't read the files at all, it has no choice but to stop everything it's doing and restart your PC．This is why the physical memory dump error appears so easily—because when a registry file is so wrong that it can't be read, your computer needs to refresh itself immediately．
This latter reason for causing the physical memory dump is actually extremely common and the likelihood is that your PC is suffering from it, if you're seeing this error．Luckily, it's also incredibly easy to fix—you just need to use a software tool called a "registry cleaner" to go through the registry and fix all the problems in there．

【推荐3】Teens interested in losing weight, for instance, got advertisements for unhealthy tips on how to become anorexic (厌食者). Such advertisements targeted these kids in hopes of persuading them to try things that were either dangerous or illegal at their age.

Advertisements are just one example of persuasion — trying to change another’s mind. Advertisements may try to convince us to buy something or do something new and different. Marketing is a field of persuasion designed to sell things, notes Jacob Teeny. Persuasion can be used to sell things. At its worst, it can be used to control people. Clearly, persuasion can be used for good and bad.

People open to new experiences tend to be more easily persuaded, Teeny says. But open-minded people can resist some persuasive arguments — such as the idea that eating junk food is cool. And closed-minded people can sometimes be persuaded. “If you haven’t really thought about the arguments” ahead of time, Teeny says, you’re going to be “much more persuadable.”

What is the main idea of Paragraph 2?

A．Marketing is designed to sell things.

B．Persuasion is used to control people.

C．Persuasion has advantages and disadvantages.

D．We should follow advertisements to buy things.

【推荐1】Like most of us, I try to be mindful of food that goes to waste. The arugula (芝麻菜)was to make a nice green salad, rounding out a roast chicken dinner. But I ended up working late. Then friends called with a dinner invitation. I stuck the chicken in the freezer. But as days passed, the arugula went bad. Even worse, I had unthinkingly bought way too much; I could have made six salads with what I threw out.

In a world where nearly 800 million people a year go hungry, “food waste goes against the moral grain,” as Elizabeth Royte writes in this month’s cover story. It’s jaw-dropping how much perfectly good food is thrown away — from “ugly” (but quite eatable) vegetables rejected by grocers to large amounts of uneaten dishes thrown into restaurant garbage cans.

Producing food that no one eats wastes the water, fuel, and other resources used to grow it. That makes food waste an environmental problem. In fact, Royte writes, “if food waste were a country, it would be the third largest producer of greenhouse gases in the world.”

If that’s hard to understand, let’s keep it as simple as the arugula at the back of my refrigerator. Mike Curtin sees my arugula story all the time — but for him, it’s more like 12 boxes of donated strawberries nearing their last days. Curtin is CEO of DC Central Kitchen in Washington, D.C., which recovers food and turns it into healthy meals. Last year it recovered more than 807,500 pounds of food by taking donations and collecting blemished (有瑕疵的) produce that otherwise would have rotted in fields. And the strawberries? Volunteers will wash, cut, and freeze or dry them for use in meals down the road.

Such methods seem obvious, yet so often we just don’t think. “Everyone can play a part in reducing waste, whether by not purchasing more food than necessary in your weekly shopping or by asking restaurants to not include the side dish you won’t eat,” Curtin says.

What does the author want to show by telling the arugula story?

A．We pay little attention to food waste.

B．We waste food unintentionally at times.

C．We waste more vegetables than meat.

D．We have good reasons for wasting food.

【推荐2】In many cultures, it is considered unlucky to spill salt. Fortunately, many cultures also have a solution to the problem, which usually involves throwing a pinch of salt over your shoulder. It may seem confusing to modern humans, but knowing that salt was once incredibly valuable can change this perspective.

For thousands of years, salt was an extremely rare commodity. It was difficult to obtain so that the price was very high. Many trading routes were set up to carry salt, people were paid in salt, and salt was sometimes worth more than its weight in gold. Therefore, spilling salt was considered wasteful.

Because of its high value, salt was also associated with friendship and good fortune. Offerings of salt were included in many religious ceremonies, and people might bring salt to a new home for good luck. These associations would have suggested that it would be bad luck to spill salt, since it would seem to violate salt’s fortunate properties.

Salt is also an excellent preservative. It prevents food from going bad. As such, it came to be linked with health and longevity. In some cultures, spilling salt was thought to reduce one's well-being. In Britain, for example, each spilled grain was said to represent a tear, while in Germany spilled salt awakened the devil, bringing misfortune.

The fear of spilling salt was also adopted into the Christian faith. It is said that Judas spilled salt at the Last Supper, and since he later turned out to be the betrayer of Christ, spilled salt is considered unlucky by many Christians.

Should you be unfortunate enough to spill salt, you might throw a pinch over your left shoulder to blind the Devil.
