For many people，volunteering is a way of life.Holidays are the time of the year that more people are in a giving mood.Homeless shelters，children’s hospitals，and nursing homes are excellent places to give of one’s time.
Volunteering in Homeless Shelters
There is a homeless directory online that anyone can easily access to find the closest homeless shelter to their home.According to the homeless shelter directory，currently there are 3,233 shelters in the US，so it is not difficult to find a shelter.Helping to serve food，picking up donations of food，preparing meals，and cleaning up are things that one can do to help at a homeless shelter.
Volunteering in Children’s Hospitals
Every child needs comfort and joy，especially during the holiday seasons.By visiting sick children in hospitals，an individual provides helping hands by supplementing the services usually done by the hospital staff.Personalizing the hospital experience adds to the comfort and happiness of the children and their families.Volunteers provide help，and positive interactions (相互交流) which enhance the patient’s quality of care.Help is needed almost everywhere in a hospital；from the lobby，parking lot，cafeteria，to admitting，helping with the gift cart，and even reading to children in the waiting rooms or their hospital rooms.
Volunteering in Nursing Homes
According to the National Center for Health Statistics，“Over 50% of those living in nursing homes do not have close relatives and 46% have no living children.”
Life in a nursing home is lonely，confusing，and frightening for many residents.Volunteering at a nursing home is a great opportunity to make a difference in someone else’s life.Playing cards，sitting with and talking to a resident，taking a walk，or sharing a meal makes a huge difference，especially when they have no other sole on earth to visit them.
The three examples above are only a small fraction of institutions in which volunteers are needed.Giving of oneself，especially during the holidays blesses and cheers others.
1．According to the passage，what can a volunteer do in nursing homes?
A．Visiting the sick children.
B．Picking up the donated food.
C．Helping with the gift cart.
D．Playing cards with a lonely old man.
2．What can we learn about the volunteering?
A．You can only volunteer during the holidays.
B．You can help prepare meals in a nursing home.
C．It is easy to find a homeless shelter to volunteer.
D．Help is needed everywhere in a homeless shelter.
3．In a children’s hospital，which of the following is true?
A．Over 50% of those living there do not have relatives.
B．A personal visit brings happiness to a sick boy.
C．Children live a lonely and frightening life.
D．Children love listening to volunteers’ reading.
4．The best title for the passage would be________.
A．Giving of oneself cheers others
B．Volunteering is a way of life
C．Volunteering during the holidays
D．Giving is better than taking

Wisdom teeth are normally the last teeth to appear.This usually happens when people are in their late teen years or early twenties，in other words，when they are older and wiser.
Wisdom teeth can grow into place normally and never cause a problem.But often there is not enough room for them in the mouth；they might crowd other teeth.Sometimes they even push sideways through the gums (齿龈)．
An impacted wisdom tooth is one that fails to completely rise through the gums.Wisdom teeth that only partly break through can leave space for bacteria to enter around the teeth.Infection (感染) is a risk in these cases.
Wisdom teeth that are not well lined and become impacted are often removed.The American Dental Association says removal is generally advised when wisdom teeth only partly break through the gums.Removal is also advised if there is a chance that wisdom teeth ate poorly lined.The best time to remove is before the teeth cause any problems or pain.Young adults are the best candidates for wisdom teeth removal.
But why do we have wisdom teeth if we often need to get them removed？One theory has to do with our diets.Scientists say the diet of ancient humans probably required more chewing teeth.Life was probably a little rougher on the teeth back then，too.So it was good to have extras.
5．According to the passage，which of the following statements is NOT true?
A．Just older and wiser people can have wisdom teeth. B．Wisdom teeth can cause problems if not in their right place.
C．Impacted wisdom teeth can’t grow out of the gum fully.
D．Wisdom teeth that only partly break can get bacterial infections.
6．Wisdom teeth should be removed________.
A．when they break through the gums
B．when they are below the gums
C．if they are not well lined or get impacted
D．if they take up enough room in the mouth
7．We can learn from the passage that________.
A．impacted wisdom teeth have the risk of getting infected
B．ancient humans need chewing teeth because of their happy life
C．older adults are the best candidates for wisdom teeth removal
D．more chewing teeth are needed for the diet of modern humans
8．The main purpose of the passage is to________.
A．advise
B．persuade
C．comment
D．introduce
