[解析]
(1)细节理解题。根据第一段After my friend kept hearing about my nightly adventures,he showed up with a gift one morning:a mosquito net.(我的朋友一直听我说这些夜间"冒险"经历后,一天早上他带着一份礼物出现了:一顶蚊帐。)可知,蚊帐是作者的朋友送给他的礼物。故选D。
(2)细节理解题。根据第三段 Then I showed him how I could borrow a drill on an app that lets us borrow things we need from your neighbors and received three responses from people living nearby within minutes,saying they' d happily lend out theirs.(然后我向他展示了如何在一个能让我们向邻居借东西的应用程序上借电钻,几分钟内就收到了三个附近居民的回复,他们说很乐意把电钻借给我。)可知,作者使用这个应用软件是为了借工具。故选A。
(3)细节理解题。根据倒数第二段"We' ll do it after I come back next week," he said. "Just be patient."("等我下周回来再弄,"他说,"耐心点。")中作者的父亲在电话里说的话可知,他建议作者耐心等待他回来,之后再一起处理这个问题。故选C。
(4)推理判断题。根据最后一段Just then I heard someone parking their car outside my house.I walked up and asked for help.To my surprise,they agreed immediately.While his girlfriend and I looked at the man in admiration,he got through the ceiling within 20 seconds.The mosquito net was finally up within a minute.(就在这时,我听到有人在我家外面停车。我走过去寻求帮助。令我惊讶的是,他们立刻同意了。我和他的女朋友钦佩地看着这位男士,他在20秒内就钻透了天花板。一分钟内,蚊帐终于安装好了。)可知,作者最终通过向他人求助解决了问题。由此可知,有时候,寻求帮助比独自努力更有效。故选B。
