（3）They're installed to solve the problem that some people take a bench too long and others can't share it.

（4）Yes. If people are asked to pay for benches, they will not take it too long when they don't really need it. Thus, every visitor will have the chance to share it. / No. Benches in parks should be free to visitors. The park can build more benches to solve its problem instead of limiting the time when visitors have a rest on benches.

【解析】【分析】这是一篇说明文，介绍了一种新型公园长椅，其不同之处在于它上面有很多尖刺，用来限制人们坐在上面的时间。安装这种椅子的目的是为了让更多的人都能分享到长椅。

（1）考查细节理解。根据第一段中的“If you don’t get up in time, it could be very painful: there are many sharp spikes on the part that you sit on!”如果你没有及时起来，那将是非常痛苦的:你所坐的部位有许多锋利的刺!可知新型公园长椅与其他长椅的不同之处在于如果你不能在有限的时间内离开它，它可能会让你痛苦。故答案为：It can limit the amount of time people sit on it (with sharp spikes). / If you don’t get up from it in limited time, it could make you painful./There are many sharp spikes on it to limit the amount of time people sit on it.。

（2）考查段落大意。根据第二段中的“Vi sitors who want a rest on the bench need to put a coin in a machine next to it. Once the money was accepted, the spikes disappear into the bench. Then visitors can sit down comfortably, but only for half an hour. When the time’s up, the spikes slowly start moving up again.”想要在长椅上休息的游客需要在旁边的机器里放一枚硬币。一旦这笔钱被接受，钉子就会消失在板凳上。然后游客可以舒服地坐下来，但只能坐半个小时。当时间到了，尖峰又开始慢慢地向上移动。可知第二段主要介绍了这种新型长椅是如何工作的，故答案为It’s mainly about how the new kind of benches work.。

（3）考查细节理解。根据第三段中的“We want to make sure that the benches are shared by more visitors, and to stop people taking a bench and staying there all day.”我们希望确保更多的游客可以共享这些长椅，并阻止人们坐在长椅上一整天。可知安装它们是为了解决有些人坐了太长时间的板凳，而有些人却无法分享的问题。故答案为：They’re installed to solve the problem that some people take a bench too long and others can’t share it.。

（4）本题为开放性题目，言之有理即可。故答案为：Yes. If people are asked to pay for benches, they will not take it too long when they don’t really need it. Thus, every visitor will have the chance to share it. /No. Benches in parks should be free to visitors. The park can build more benches to solve its problem instead of limiting the time when visitors have a rest on benches.。【点评】本题考点涉及细节理解，段落大意以及开放题型的考查，是一篇科研类阅读，要求考生准确掌握细节信息，根据上下文的逻辑关系，进行推理，概括归纳，从而写出正确答案。
