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.

1.The underlined word “lucrative” in the passant’ probably means “________”

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.

Our Great Ocean Road Adventure

By Donna Waverley

My family and I recently went to Australia, to see my grandparents. But before we visited them, we went sightseeing along the Great Ocean Road, on the Australian coast.

Dad had planned to drive, but even though he was used to driving miles without getting exhausted, he then read on the website that the road wouldn’t be an easy drive. Anyway, we thought he deserved to enjoy the fantastic views too, which he couldn’t do as our driver. So instead, we booked discount bus tickets and off we went.

Our first stop was where wild kangaroo lived – and Dad and I were taking a walk when a big one appeared! For a moment, it seemed to consider coming towards us, which made me a little nervous – but then it went off along the road and into the bushes.

That wasn’t the only wildlife we saw. I thought it unlikely we’d see famous Koala bears during our short visit. In fact, at our next stop, we saw roughly six million in that area! Sadly, some gum trees they were in had very few leaves left, which people told us was because of the Koalas, although I’d read that lack of water is indeed the problem.

Dad had booked a campsite for the night, with ready-made tents – for an adventure! I wasn’t sure about that, but they were really luxury tents, within walking distance of some famous rocks and other places we hoped to visit. However, Dad also said the sounds of wild creatures would help us sleep. That sounded worrying – until the “wild creatures” turned out to be frogs! So I was embarrassed by my fears – and kept awake by the frogs! But we had fun making meals together – we’d brought food, as we knew there’d be nowhere to eat.

In fact, this whole trip was fantastic!
