Directions: There are 2 passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four choices marked A）, B）, C）and D）. You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.

Passage One
Questions 46 to 50 are based on the following passage.

Educators and business leaders have more in common than it may seem. Teachers want to prepare students for a successful future. Technology companies have an interest in developing a workforce with the STEM （science, technology, engineering and math）skills needed to grow the company and advance the industry. How can they work together to achieve these goals? Play may be the answer.
Focusing on STEM skills is important, but the reality is that STEM skills are enhanced and more relevant when combined with traditional, hands-on creative activities. This combination is proving to be the best way to prepare today’s children to be the makers and builders of tomorrow. That is why technology companies are partnering with educators to bring back good, old-fashioned play.
In fact many experts argue that the most important 2lst-century skills aren’t related to specific technologies or subject matter, but to creativity; skills like imagination, problem-finding and problem-solving, teamwork, optimism, patience and the ability to experiment and take risks. These are skills acquired when kids tinker（鼓捣小玩意）. High-tech industries such as NASA’s Jet Propulsion Laboratory have found that their best overall problem solvers were master tinkerers in their youth.
There are cognitive（认知的） benefits of doing things the way we did as children—building something, tearing it down, then building it up again. Research shows that given 15 minutes of free play, four- and five-year-olds will spend a third of this time engaged in spatial, mathematical, and architectural activities. This type of play—especially with building blocks—helps children discover and develop key principles in math and geometry.
If play and building are critical to 21st-century skill development, that’s really good news for two reasons:Children are born builders, makers, and creators, so fostering（培养） 21st-century skills may be as simple as giving kids room to play, tinker and try things out, even as they grow older. Secondly, it doesn’t take 21st-century technology to foster 21st-century skills. This is especially important for under-resourced schools and communities. Taking whatever materials are handy and tinkering with them is a simple way to engage those important “maker” skills. And anyone, anywhere, can do it.
