3 . It was Jennifer Williams’ mother who got her interested in books. As a librarian, Williams’ mother read to her three children every day. “From when we hadn’t gone to kindergarten,” Williams told vadogwood.com, a local news site, “until we went to college.”

When Williams, who is now 54, became an elementary school teacher and tutor in Danville, Virginia, she wanted her students to be falling in love with reading just as she had. But early on, she realized that some kids had little chance to get enough books to read.

To Williams, the solution was simple: give kids books. In 2017, she donated (捐赠) 900 used children’s books over three days. “I wanted to do something that’s going to continue my faith,” she said.

So she started a new project for herself: give away one million books. It sounds like an unreachable number, but as Williams posted on Facebook: “Don’t complain in the stand if you aren’t willing to work hard out on the field.”

She got to work, first by persuading her friends to donate books or money to buy books. Before long, as news of Williams’ project spread, strangers started leaving varieties of books on her front walk way. As quickly as the books came in, Williams gave them to local schools—free of charge —and also supplied 41,000 books to little free libraries around the city just over the North Carolina border. She also hosted a book club for prisoners in the local prison.

Over the four years she’s been doing all this. The Book Lady, as Williams has come to be celebrated, has given away more than 78,000 books—only 922,000 more to reach her goal! And she’s not slowing down. “Reading can take you anywhere,” she told CNN. “You can travel in time and space. If you can read, you can learn almost anything.”

Forgetfulness can be     1     problem both in study and daily life. That is why people use tools like flashcards, puzzles and brain twister games-to force their brains     2     (save) more information.

But, according to a recent study     3    (publish) in the journal Neuron, forgetting has its own uses. Forgetting things improves the efficiency of memory and     4     (help) us to make better decisions.

The point of memory,     5     is known to us, is “to hold on to valuable information”. That’s because our brain has only a limited capacity (容量) to store the information we input. If we try to remember everything     6    (accurate), some useful things will be missed.

What’s more, sometimes too many     7     (detail) can cause mental chaos (混乱) and stop us from     8     (make) the right decision.

If you’re trying to learn the world and “your brain is constantly bringing up many conflicting memories,” said a Canadian     9     (science) in neurology (神经学) called Blake Richards in a news conference, “that makes     10     harder for you to make the right decision.”

8 . For many parents, raising a teenager is like fighting a long war, but years go by without any clear winner. Like a border conflict between neighboring countries, the parent-teen war is about boundaries: Where is the line between what I control and what you do?

Both sides want peace, but neither feels it has any power to stop the conflict. In part, this is because neither is willing to admit any responsibility for starting it. From the parents’ point of view, the only cause of their fight is their adolescents’ complete unreasonableness. And of course, the teens see it in exactly the same way, except oppositely. Both feel trapped.

In this article, I’ll describe three no-win situations that commonly arise between teens and parents and then suggest some ways out of the trap. The first no-win situation is quarrels over unimportant things. Examples include the color of the teen’s hair, the cleanliness of the bedroom, the preferred style of clothing, the child’s failure to eat a good breakfast before school, or his tendency to sleep until noon on the weekends. Second, blaming. The goal of a blaming battle is to make the other admit that his bad attitude is the reason why everything goes wrong. Third, needing to be right. It doesn’t matter what the topic is—politics, the laws of physics, or the proper way to break an egg—the point of these arguments is to prove that you are right and the other person is wrong, for both wish to be considered an authority—someone who actually knows something—and therefore to command respect. Unfortunately, as long as parents and teens continue to assume that they know more than the other, they’ll continue to fight these battles forever and never make any real progress.
