David knew the waterfall was coming. It wasn't his first visit to the river in central California. He figured he would hop out of his raft into the sallow water, rappel down the rocks (沿岩壁下降)on either side of the fall, and continue on his way, as he had on a previous trip.

But this year was different. Heavy snow and spring rains had turned the usually manageable falls into something fierce. And this year, instead of his friends, David's companions were his girlfriend, Sara, and his l3-year-old son, Hunter. As the three of them approached the falls late in the afternoon of the third day of their camping trip, David could tell from the increasing roar of water in the narrowing valley that they were in serious trouble. There was no way they 'd be able to rappel down the rocks as planned.

They could wade (蹚水) to the shore, but would anyone find them there? They had no phone service, and they hadn't seen a single person in the past three days. And David knew they'd be sharing the ground there with snakes and mountain lions.

As he wondered what to do, David hit on a bit of luck he heard voices coming from the other side of the fall. He yelled, but the sound of the rushing water drowned him out.

We had to do get these people a message, David thought. He caught a branch and pulled out his pocketknife to carve“Help" in it. Then he tied a rope to it so the people would know it wasn't just any branch. He tried flying it over the falls, but it floated away in the wrong direction.

Then he spotted his green water bottle David grabbed it and carved “Help!” on it Sara also reminded him that he had a pen and paper, which she'd brought to play games with, in his backpack.

David knew it was just an attempt. But he wrote down“6- 15-19 We are stuck here at the waterfall. Get help please”and pushed the note into the bottle.

Paragraph l:

This time, his throw over the waterfall was perfect.

According to a new study published in the Journal of Cognition, walking backwards, whether doing it really or just imagining it, can boost (增强) the brainpower in the short term.

In the study, 114 volunteers were asked to watch a video in which a woman had her bag stolen. Then they answered 20 questions about the details shown in the video. Ten minutes after watching the video, the volunteers were divided into three groups. The first two groups were told to move forwards or backwards 10 meters while the third group was asked to stay still on the same point. The researchers found that the backwards-walking group got two more correct answers on average than the other two groups. This suggests that a relationship between the concepts (概念) of time and space is essential to the way our minds form memories.

When we walk backwards, everything we learn becomes strange to us. "This forces the brain to think in a different way—it's a rewiring and changes the focus," US neuropsychologist (神经心理学家) Christine Weber told Forbes. It almost always means that our brain needs to be more active and alert in the limited time. Naturally, our short-term memory will be improved significantly.

Apart from improving our memory, walking backwards also plays an important role in physical health, especially fitness. A study published in Journal of Biomechanics in 2012 found that backward walking puts less strain and requires a smaller range of movements from the knee joints (膝关节). Thus, there's less pressure and pain in the knees.

In addition, walking backwards, compared to forward walking, is more challenging. It requires you to use muscles and movements that you probably rarely use, making it a perfect way to change your exercise routine for greater fitness gains. Meanwhile, by making people put in extra effort, it naturally burns more fat and calories.

【1】Which group of people perform best in the memory test?

A.The staying-still group.B.The forwards-walking group.

C.The imaginary-walking group.D.The backwards-walking group.

【2】In what way does walking backwards benefit people's health?

A.It can make people slim.B.It can reduce peopled stress.

B.It limits people's thinking time.

C.It directs our focus to important details.

D.It makes people's brain more active and alert.

【4】What's the writer's purpose in writing paragraph 4?

A.To add another aspect of the topic.

B.To support the result of the research.

C.To sum up the main idea of the passage.

D.To provide some background information.
