试题分析：
【1】本题主要考查了太阳大气层，太阳外部结构的三个层次从里到外依次是光球、色球、日冕，故答案选C项。
【2】主要考查了太阳大气的结构及太阳活动的类型，光球层上太阳活动类型是黑子，色球层上太阳活动类型是耀斑，是突然增大、增亮的斑块；日冕层上太阳活动类型是太阳风。故选C．
【3】太阳活动是指发生在太阳外层大气层上的现象，包括了黑子，耀斑，日珥和太阳风，
太阳活动会对气候产生一定的影响，但不会使温度升高很多，但会影响降水，①错④对；耀斑爆发会产生大量的高能粒子，作用到地球就是破坏高层大气中的电离层和扰乱磁场。电离层破坏后往往无线电短波通讯会中断，②对； 太阳风携带的高能粒子会受地球磁场的影响，从而会产生磁暴现象，③对。故答案选B项

【题目】D
Four years ago, Chris Nagele did what many other technology CEOs have done before — he moved his team into an open concept office.
His staff had been working from home, but he wanted everyone to be together, to bond and communicate more easily. It quickly became clear, though, that Nagele had made a huge mistake. Everyone was distracted, productivity suffered and the nine employees were unhappy, not to mention Nagele himself. In April 2015, about three years after moving into the open office, Nagele moved the company into a 10,000-square foot office where everyone now has their own space — complete with closing doors.
Numerous companies have embraced the open office — about 70% of US offices are open concept — and by most accounts, very few have moved back into traditional spaces with offices and doors. But research that we’re 15% less productive, we have great trouble concentrating and we’re twice as likely to get sick in open working spaces, has contributed to a growing backlash(反对) against open offices.
Since moving, Nagele himself has heard from others in technology who say they long for the closed office lifestyle. It’s unlikely that the open office concept will go away anytime soon, but some companies are following Nagele’s example and making a return to private spaces.
There’s one big reason we’d all love a space with four walls and a door that shuts: concentration. The truth is, we can’t multitask and small distractions can cause us to lose concentration for more than 20 minutes. Beside the cheaper cost, one main argument for the open workspace is that it increases teamwork. However, it’s well documented that we rarely brainstorm brilliant ideas when we just talk casually in a crowd.
【1】 How did Nagele feel three years after moving into the open office?
A. He felt satisfied with it.
B. He felt doubtful about it.
C. He regretted his decision.
D. He was confused about it.
【2】 What made Nagele move the company in April 2015 again?
A. The suggestions from his friends.
B. The cheaper cost of the new office.
C. The complaints from his employees.
D. The negative results of the open office.
【3】What do we know about offices from the text?
A. The minority of US companies choose open offices.
B. Nagele influenced some companies to move offices.
C. Many US companies are moving into private offices.
D. Open offices will soon be replaced by traditional ones.
【4】 What is the best title for the text?
A. Open workspace matters a lot
B. Why open offices are bad for us
C. Productivity suffers in private space
D. New trends of offices excite companies
