4. Passage FourteenFor a long time， people have disagreed about whether golf is a sport or a game.On one side of the argument， people say that golf meets the dictionary definition of a sport， because it is a physical， athletic activity.They add that golf is recognized as a sport by sporting goods companies， athletic groups， fans， and the media.Also， golf’s inclusion in the Olympics in 2016 is more proof that it is a sport.On the other side， people say that golf is a game， not a sport.They say golf is not a very physical activity and can be played well by people who are overweight or injured.Also， golf was only recently added to the Olympics.For more than 100 years it was not included in the Olympic Games.For many， the Olympic Games serve as a measurement for whether an activity should be called a sport.Golf was first included in the Olympics in 1900.However， it was removed shortly thereafter because of a lack of participation and conflict with other golf events.Through the years， there were several attempts to bring golf back to the Olympics.It wasn’t until the 2016 Summer Olympics in Rio de Janeiro， Brazil that golf returned.Some say the return of golf does not prove that it is a sport.Rather， it only proves that the Olympics wanted to benefit from the star power of famous golfers like Tiger Woods.The disagreement continues today.Those who think golf is a sport point to pro-golfers like Woods， who are strong and fit.Those who disagree point to golfers like John Daly.He is a successful pro-golfer who once had health problems.So is golf a sport? The answer depends on who you ask——and whether that person owns a set of golf clubs.According to Paragraph 5， the inclusion of golf in the Olympics ().

4. Passage Twenty-TwoThough some people have suggested that women should return to housework in order to leave more jobs for men， the idea has been rejected by both women and men in public opinion polls (民意测验).Lately some union officials have suggested that too many women are employed in type of work more suitable for men and that women should step aside to make way for unemployed young men.They argue that women—especially women in their childbearing years actually delay economic development and result in lower productivity， poor quality and inefficiency.To solve the problem， they have suggested that the working women stay at home while their husbands or brothers were given double wages.They argue that under these circumstances， families would retain their same level of income， and women could run the house and raise children much better.The suggestion has been rejected by 9 out of 10 people polled.A hundred persons in a big city were questioned last summer.Out of 50 women， 46 said they were unwilling to leave their jobs， no matter what the situation was.The other 4 said they would like to return home if their jobs could be taken by their sons or daughters.Of 50 men polled， only 6 said they would like to see their wives give up their jobs， if it meant higher wages for themselves.Some other people have suggested another way called “phased employment theory”.The theory suggests that a woman worker take leave from her job when she is seven months pregnant (妊娠)and stay off the job until her baby reaches the age of 3.It suggests that women on leave receive 75 percent of their normal salary and be allowed to return to work after the 3-year period.This will benefit children， women， their families and the society.Some of those polled， both women and men， felt the idea is a good one.It definitely seems to be more acceptable than the suggestion that women return to home forever.From the passage we can see “phased employment” means ().
