    Race walking shares many fitness benefits with running, research shows, while most likely contributing to fewer injuries. It does, however, have its own problem.

Race walkers are conditioned athletes. The longest track and field event at the Summer Olympics is the 50-kilometer race walk, which is about five miles longer than the marathon. But the sport’s rules require that a race walker’s knees stay straight through most of the leg swing and one foot remain in contact (接触) with the ground at all times. It’s this strange form that makes race walking such an attractive activity, however, says Jaclyn Norberg, an assistant professor of exercise science at Salem State University in Salem, Mass.

Like running, race walking is physically demanding, she says, According to most calculations, race walkers moving at a pace of six miles per hour would burn about 800 calories(卡路里) per hour, which is approximately twice as many as they would burn walking, although fewer than running, which would probably burn about 1,000 or more calories per hour.

However, race walking does not pound the body as much as running does, Dr. Norberg says. According to her research, runners hit the ground with as much as four times their body weight per step, while race walkers, who do not leave the ground, create only about 1.4 times their body weight with each step.

As a result, she says, some of the injuries associated with running, such as runner’s knee, are uncommon among race walkers. But the sport’s strange form does place considerable stress on the ankles and hips, so people with a history of such injuries might want to be cautious in adopting the sport. In fact, anyone wishing to try race walking should probably first consult a coach or experienced racer to learn proper technique, she says. It takes some practice.

    Making beers on the moon might seem like a pipe dream to many, but for a group of students from the University of California at San Diego, there is a chance to take their research beyond Earth’s surface.

The Lab2Moon competition, held by TeamIndus, is offering students the chance to secure a spot on the TeamIndus rocket this year.

Taking craft beer to the next level, the students want to test whether it’s possible for yeast(酵母) to work and create beer on the moon. However, they believe the experiment is not just a creative concept for astronauts, it’s also important for the development of drugs and yeast-containing food, like bread.

“The idea started out with a few laughs among a group of friends,” said Neeki Ashari, a fifth-year bioengineering students at UC San Diego. “We all appreciate the craft beer. When we heard that there was an opportunity to design an experiment that would go up on India’s moonlander, w e thought we could combine our hobby with the competition by focusing on the practicality of yeast in outer space.”

The preparation work for the beer — up to the stage of adding yeast — will all be done on Earth, and rather than separating the fermentation ( 发酵) and carbonation stage of making beer, the team plans to combine them.

This removes the need to release CO2 accumulated in the process, which may result in cleanliness and safety issues out in space.

If selected, Team Original Gravity will be the first to make beer in outer space, and the fermentation will take place in a container no bigger than a soda can.

All teams competing for the place will showcase their ideas in Bangalore, India, in March.

Sadly, you won’t be enjoying moon beer in your local craft beer bar anytime soon, as no samples will be brought back. However, this small experiment could provide important data on just how practical it is for us to make and create our own resources on other planets and moons by learning how consumables (消耗品) behave in different environments.

100．How did the students feel when they got the chance to design the experiment ?

A．Excited.                                                    B．Nervous.

C．Confident.                                                 D．Casual.

101．What does the underlined word “This” in Paragraph 6 refer to?

A．The mixing of two stages.                           B．Adding yeast on Earth.

C．The preparation work on Earth.                   D．Fermentation and carbonation.

102．What can we learn about the experiment from the passage?

A．It has been designed based on similar experiments.

B．It’s quite competitive compared with other designs.

C．It’s design has already been approved by TeamIndus.

D．Its process was adapted to make it safer and greener.

103．What does the author think of the students ’ idea?

A．It seems like a pipe dream.                          B．It’s extremely complicated.

C．It’s meaningful and hopeful.                        D．It’s creative but impractical.

    Along with soccer, basketball is a global sport. As you read this. young people somewhere in the world are happily passing, dribbling(运球) and shooting. It’s enormous fun and a joyful way to spend time with others.

Basketball is a game for everyone. Unlike golf or tennis. it doesn't require great wealth or a lot of space to play. After all, not many people have a golf course-sized backyard. and tennis equipment is expensive. Basketball, by contrast, just needs a wall with a hoop and a ball.

So after its invention by Canadian-American physical educator James Naismith in 1891, the sport took off within US citizens, who quickly became attracted to the game because it suited their circumstances. Today, 127 years later, basketball remains one of the most popular sports in the US, and the National Basketball Association (NBA)has an increasing appeal for fans around the world.

The success of basketball as global phenomenon is undoubtedly related to the way African-Americans play the game.” The basketball court reflected some of the major cultural shifts in America, such as from forbidding African-Americans to play basketball to allowing them to play in the NBA, "the LIVESTRONG website noted.

From the 1950s onwards, segregation rules, which had prohibited African-Americans from playing basketball in NBA games, were no longer used in the US. In 1950, when Earl Lloyd started to play for the Washington Capitols, things began to change. Since then, most of the greats of the game have been African-Americans, like Michael Jordan, Magic Johnson, Kobe Bryant and LeBron James.

It's not difficult to see that there's a strong link between political liberation and basketball. Something of this is expressed in a quote from the US author John Edgar Wideman. He makes a connection between basketball and hope:" When it's' played the way it's supposed to be played. basketball happens in the air; flying, floating, raised above the floor, letting the oppressed(受压制的) people of this earth imagine themselves in their dreams.”
