Another man who was standing nearby got into the car and put on the e handbrake, saving the girls from injury.
It was at this point that Patti noticed his own car rolling slowly down the hill and going too fast for him to stop it. It crashed into a bus at the bottom of the hill and was so badly damaged that it had to be pulled away to a garage.
As if this was not bad enough, Paul now found he had no one to blame. He was so busy chasing his car that he didn't get the name of the driver of the sports car, who just came out of the supermarket and drove away without realizing what had happened.

Most episodes of absent-mindedness--forgetting where you left something or wondering why you just entered a room--are caused by a simple lack of attention, says Schacter. "You're supposed to remember something, but you haven't encoded it deeply."
Encoding, Schacter explains, is a special way of paying attention to an event that has a major impact on recalling it later. Failure to encode properly can create annoying situations. If you put your mobile phone in a pocket, for example, and don't pay attention to what you did because you're involved in a conversation, you'll probably forget that the phone is in the jacket now hanging in your wardrobe(衣柜). "Your memory itself isn't failing you," says Schacter. "Rather, you didn't give your memory system the information it needed."
Lack of interest can also lead to absent-mindedness. "A man can recite sports statistics from 30 years ago, "says Zelinski, "may not remember to drop a letter in the mailbox "Women have slightly better memories than men, possibly because they pay more attention to their environment. and memory relies on just that.
Visual cues can help prevent absent-mindedness, says Schacter. "But be sure the cue is clear and available, "he cautions. If you want to remember to take a medication (药物) with lunch, put the pill bottle on the kitchen table--don't leave it in the medicine chest and write yourself a note that you keep in a pocket.
Another common episode of absent-mindedness: walking into a room and wondering why you're there. Most likely, you were thinking about something else. "Everyone does this from time to time," says Zelinski. The best thing to do is to return to where you were before entering the room, and you'll likely remember.
Why does the author think that encoding properly is very important？

It is in the joints of human body that movements of the bones take place. The movement itself is caused by the pull of sheets and cords of very tough tissue(组织) called muscle. Muscle tissue has the special ability to shorten itself so that the bone on which it pulls has to move. When muscle tissue shortens, it also bunches up (凸起). Muscle tissue covers the body in sheets, and bands that lie between the skin and the skeleton. The bones are the framework of the body, but the muscles fill out the body shape. Most muscles extend from one bone to another. When the muscle between the bones shortens, one bone has to move. The point where the muscle is fastened to the unmoving bone is called the origin of the muscle, whereas the point where the muscle is fastened to the bone that is to be moved is called the insertion. Sometimes the muscle is not attached directly to the bone but to a tough, non-stretchable cord, or tendon that is attached to the bone.
Muscles do not push; they can only pull. To bend the arm at the elbow the muscle at the front of the upper arm has to shorten and bunch up. To unbend the arm, other muscles in the back of the arm have to shorten. These two sets of muscles--the front and back--are said to act in opposition to each other. When one set is working, the other set is usually relaxed. But there are times when both of them work. Sometimes muscles are called upon to do more than simply pull in one direction. They may have to perform. a turning motion. To be able to do this, the muscle must be attached to the bone at an angle. By pulling, the muscle can cause the bone to pivot.
According to the passage, movement occurs when a muscle______.
