3 . The rapid growth in skyscrapers worldwide has led to a high demand for window washers since most of these buildings feature large glass panes (窗格) to highlight their breathtaking views.

Though the job offers a handsome salary, dangling alongside multi-story structures is dangerous, and accidents are not uncommon. However, if Israel-based company Skyline Technologieshas its way, the dangerous chore may soon be taken care of by Ozmo, an intelligent window cleaning robot.

"As a society, we've become too comfortable watching people hanging off the sides of 30-story buildings," says Yaron Schwarez, co-founder and CEO of Skyline Robotics. "No salary could justify allowing people to put their lives in the hands of a system of ropes."

Much like humans, Ozmo is placed on platforms suspended from the buildings and uses its arms and brushes to clean the dirt on the glass panes. A 3D map of the building's surface programmed into its system allows the robot to skillfully handle obstacles as it moves up and down the structure. Computer vision and touch sensors enable it to move out of the way in case of unexpected events, such as the sudden opening of a window.

Unlike current window washers, the robot cleaner does not require soap to clean the glass. Instead, it uses distilled water (蒸馏水) and a process called dirt absorption to do the job. Schwarez explains, "We use pure water to absorb and remove the salts, the minerals, the oils, and the dirt from the building. We are environmentally-friendly."

Ozmo is also expected to be much more efficient than humans. While it currently 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. It will only make their jobs safer by lifting them to the role of supervisors, who will be remotely controlling the operation from below.

Whether Ozmo, which is still undergoing testing, does as good a job as human remains to be seen.

4 . Hundreds of children are being treated for sleep problems in Wales every year. In some cases，babies，infants (婴儿)and teenagers have been admitted to hospital in north Wales alone.

The Children’s Sleep Charity said many children were suffering from lack of sleep mainly because of technology use. Public Health Wales said sleep was as important to a child’s health as healthy eating and exercise，and children with poor sleep patterns were more likely to be fat.

Statistics obtained (获得) under the Freedom of Information Act by BBC Wales found at least 408 children have been admitted to hospitals across Wales suffering from sleep disorders since March 2013.

Children aged between 0 and 4 made up the highest number of inpatients (住院病人)，with some newborns being treated for sleep-related problems from the day of birth.

Vicki Dawson，who set up the Children’s Sleep Charity (CSC)，said sleepless nights were putting both children and parents in anxiety. “Their weight and growth may also be affected as well as their mental health，”she said.

Teachers said children showing signs of sleep shortage and tiredness in class were a concern as they couldn’t concentrate for long periods.

Psychologist Amy McClelland，of Sleep Wales，saida common problem was that children were “over excited”before bed and that families should get back to basics. “Think 1950s family home. Dinner as a family，read，chat，a film maybe，lights off and then bed. ”She added.

1. What’s the main reason why children are short of sleep？

A．Less exercise.	B．Eating habits.
C．Technology use.	D．Sleep patterns.

2. Who are the majority of the inpatients with sleep-related disorders？

A．Infants.	B．Teenagers.
C．Teachers.	D．Parents.

3. What can we infer from what Amy McClelland said？

A．Chatting and films make children sleep more.

B．It is difficult for children to read before bed.

C．Being too excitedis good for sleep habits.

D．Relaxation has a bad effect on children.
