On Friday, 7 June, an Italian Airlines flight was ready to leave Rome for Tokyo in Japan. All the passengers were on the plane. The departure time was 21:00. The seatbelt signs were turned on, so passengers were not allowed to stand up and had to stay in their seats. Then something unusual happened.
A woman decided that she had to go to the toilet. So she got up and walked to the back of the plane. The toilet door was clearly marked ‘TOILET’, but the woman opened a door next to the toilet. This door was the emergency exit and, when she opened it, the evacuation slide (逃生滑梯) opened. Because of this, the plane was not able to take off.
All the passengers had to leave the plane. When the evacuation slide has opened, there are two possibilities. Workers can change the slide at the airport, but the flight will be delayed for a long time. Or the plane can take off without an evacuation slide and replace it when it has landed, but the number of passengers on the plane must be smaller for safety reasons.
Thirty-eight passengers had to stay at a hotel at the Airport and take another flight the next day. The other passengers got back on the plane, and it finally took off at 05:10 on Saturday morning. It arrived in Tokyo at 14:10. Some passengers found that their luggage was still in Italy. But perhaps they were lucky …

The growth in skyscrapers (摩天大楼) worldwide, most of which have large glass panes, has led to a great need for window washers. Though the job, which earns workers as much as $35 an hour, can be lucrative, accidents are not uncommon. However, the dangerous chore may soon be done by Ozmo, an intelligent window cleaning robot, with humans supervising (监督) from the safety of the ground.
Much like humans, Ozmo, hanging off the sides of the building, uses its arms and brushes to clean the dirt and grime on the glass panes. A 3-D map of the building programmed into its system allows the robot to skillfully move up and down. Computer vision and touch sensors (传感器) enable it to move out of the way in case of unexpected events, such as the sudden opening of a window. And the robot will self-correct and move around it so as not to break a window.
Unlike other window washers, the robot cleaner does not require soap or Windex to clean the glass. Instead, it uses purified water (纯净水) and a process called reverse osmosis (反渗透) to do the job. It is environmentally friendly.
While it takes three cleaners 480 hours each to clean the windows of a 40-story glass building, the robot will single-handedly complete the task in just 80 hours. However, unlike other robots, Ozmo will not replace human workers, only making their jobs safer. Human workers will control the robot from below.
Whether Ozmo, which is still undergoing testing, docs as good a job as humans remains to be seen. * Past efforts to use a robot to do this dangerous job have not been successful, because the machines do not have the same eye as humans and often miss the soot (烟垢) collected on window corners.

A.安全的 B.危险的 C.赚钱的
2.The second paragraph mainly tells us
A.why Ozmo is much more intelligent than human workers
B.how Ozmo works to clean the glass smartly
C.what makes Ozmo an intelligent window cleaning robot
3.What does Ozmo use to clean the glass?
A.Purified water. B.Soap. C.Grime or soot.
4.To finish the task of cleaning the windows of a 40-story glass building, Ozmo spends ________ hours less than a cleaner.
A.560 B.400 C.1,360
5.Which of the following is TRUE about Ozmo?
A.As an intelligent window cleaning robot. Ozmo is successful.
B.Ozmo does harm to the environment while cleaning the window.
C.Ozmo can make human window washers do their jobs safely.
