Half of all bosses say a lack of sleep makes them irritable (易怒的) and prone to(有……傾向的) shout at their staff, a study said.

One in five managers also said being kept awake at night meant they were more likely to make mistakes, the Mori poll of 1,006 people revealed(顯示).

Some 48% of people aged 35 to 44 said they did not get enough sleep compared to a national average 39%.

Among that age group, people with young children and managerial (管理的) jobs were most likely to suffer. 

The report, commissioned (委托) by the think tank De??mos and Ikea, said the issue of sleep had been forgotten in the work / life balance debate.

Report author Charles Leadbeater said, "On any working day, a quarter of all managers in Britain are likely to be in a bad mood because they have not slept well. "

"These sleep-deprived and shouty managers with a tend??ency to make mistakes are responsible for millions of British workers. It’s hardly a recipe for good management. "

And Mr. Leadbeater called on the government and em??ployers to take action.

A small loss of sleep is likely to have a big impact on people who lead stressful lives.

"Stressed out parents are already not sleeping enough. They are the people most likely to have their sleep disrupted and they are least able to recover."  

Apart from children keeping their parents awake, worrying about work is the biggest cause of wakefulness at night among managers.

Women are five times more likely than men to lose sleep because their partners snore (打呼嚕).

The report predicted that there was likely to be a growing market of　sleep-deprived people, with an increase in "public napping".

Opportunities to take a nap at work are also likely to in??crease, and the report recommended that employers take their responsibility for ensuring employees were well slept more se??riously.

Peter Jelkeby, marketing manager at Ikea, said the re??search confirmed suspicions Britons were not getting enough sleep.  

And he added: "This is having a detrimental effect on our society as a whole. "

9. Which of following is true according to the text?

A. Half of the people say a lack of sleep makes them irrita??ble.

B. 20% managers said being kept awake at night meant they were more likely to make mistakes.

C. Some 48% of people said they did not get enough sleep.

D. People with young children and managerial jobs were most likely to suffer.

10. What does the underlined word "detrimental" mean?

A 良好的.          B.有害的           C.片面的     D.致命的

11. Who that suffered sleep disrupted are least able to recover?

A. The bosses.                 B. Managers.

       Below is a housing guide for students going to London.

University accommodation office

Many university accommodation offices have their own list of registered landlords (房東). Others also provide information on accommodation agencies and other housing organizations. The advantage of using your university accommodation office is that you can get some support if you have 'a problem. The disadvantage is that they are unlikely to have enough registered landlords to house all their students.

Property papers: Loot and Renting

Loot is an important source (來源) of information about private housing for co-renters. The offers are from private landlords, agencies and individuals looking for other co-renters. They also have a website: www. loot. com. The advantage of using Loot is that there are some excellent bargains. The disadvantage is that there is no quality control over the offers.

Renting is another useful paper. The offers in this paper are mainly from accommodation agencies. Their website is at www. Renting.co. uk.

Accommodation agencies

The majority of rented accommodation in London is probably advertised through accommodation agencies. The advantage of using accommodation agencies is that you will have access to a large number of accommodations. A good agent will listen to your requirements and can save you time in looking for the right accommodation. The disadvantage is that they will make a range of charges to potential renters.

Noticeboards

Around the universities you will find a number of noticeboards where offers of accommodation will be posted. These will either be from landlords or from students. Some universities will also have online noticeboards where students can advertise to other students. Advertisements from students can be an excellent way to find accommodation. However, advertisements from landlords can be problematic.

Word of mouth

Some of the best housing in London is never advertised but is passed on from one group of students to another by word of mouth. It might be that you can find out about good offers from final year students. However, don't suppose that just because you have found out about housing from a friend it is necessarily, going to be better than that found through any other source.
