Read the passage carefullyThen answer the questions or complete the statements in the fewest possible words.

Most people look forward to retirement as a time when they can finally take up activities that they never had the time or energy to pursue before.But some recent studies on people in their golden years are disturbing: they suggest that retirees are more likely to suffer from depression and possibly higher rates of other diseases such as heart disease and high blood pressure.That’s why a new study of French workers is welcome news.

Led by Hugo Westland, a professor of psychology at Stockholm University, the study of more than 14,000 workers found lower rates of depression and fatigue (疲劳) in people after they got tired while they were still employed.

The scientists followed the employees of the French national gas and electric company for 14 years.They found in the year immediately after retirement, the volunteers reported 40% fewer depressive symptoms than they had in the year before their retirement.The researchers also found an 81% drop in reports of both mental and physical fatigue over the same time period.

Clearly, said Westerlund, much of these decrease in physical and mental fatigue can be traced back to relief from the stresses of work.The decline in depressive symptoms suggests that retirement may be having a positive mental effect, too, which may have a lot to do with the generous pensions (养老金) that French workers enjoy.Most retirees in that country still benefit from about 80% of their yearly salaries.

“The economic or financial situation in retirement is very important,” Westerlund says.“We don’t know if the decrease in fatigue and depressive symptoms is because of the removal of something bad while in work or the addition of something good while in retirement.But no matter the reason, if life in retirement is not comfortable, then we won’t see the improvements we did.”

However, in European nations like France, governments are considering changes to pension plans, which may affect retirees’ health after they leave their jobs-with less of a financial safety net, workers may no longer seem so mentally and physically happy to be out of work.   

(Note: Answer the questions or complete the statements in NO MORE THAN EIGHT WORDS.)

1.According to some recent studies, retired people may have depression and higher rates of other diseases like __________.

 

 

2.Westerlund’s group found that in the year just after the retirement most retired French workers felt much less tired both __________.

 

3.What does the word “improvements” in paragraph 5 refer to?

 

4.Retirement may make people happier with __________.

Directions: Read the following text and choose the most suitable heading from A-F for each paragraphThere is one extra heading which you do not need.

A.Causes of overusing fluoride

B.Negative effects of fluoride

C.Safe use of fluoride

D.The expert’s background information

E.No need to worry about fluoride poisoning

F.Solutions to improper use of fluoride

I have heard that fluoride can help stop dental decay, but I recently read that it is poisonousWhich of these is true? How can children use fluoride safely?

1.

 

This question is answered by Dr Marcia M.Rich who practises general dentistry in Newholt.She is also a lecturer at the University and a writer for the monthly magazine Your Dentist Cares

2.

 

My answer to the first question is to stress that fluoride works well and is safe when users follow instructions.Young children have a tendency to swallow toothpaste, which is why they should only have a tiny amount of fluoride toothpaste on their toothbrush.If this simple measure is taken, parents can be confident that children will be protected against tooth decay, and come to no harm.

3.

 

Almost all medicines have an adverse effect-or even be deadly-if they are not taken as directed.So you are right-fluoride can be poisonous if it is swallowed in very large quantities.It is for the reason that fluoride supplements can only be obtained on prescription from the doctor or dentist.Please be assured that fluoride overdoses are rare-in fact, I have never heard of any fatal incidents related to fluoride poisoning.

4.

 

Scientific studies have shown that fluoride can help to prevent cavities as long as it is used correctly.If fluoride is abused, there is a risk of illness or even deaths in extreme cases.If a deadly amount of fluoride is taken, immediate first-aid could save a life.A person who has swallowed a large amount of fluoride will probably start vomiting.If not, the patient should be given milk or antacid and taken to the nearest hospital for emergency treatment.

5.

 

Taking too much fluoride while teeth are growing can lead to a condition called dental fluorosis.The most likely cause is the swallowing of fluoride toothpastes by young children.It can also be caused by inappropriate use of fluoride drop or other fluoride supplements, for example when fluoride is already is already present in drinking water.
