Mental health is our birthright. (46) We don’t have to learn how to be mentally healthy ;it it built into us that our bodies know how to heal a cut or mend a broken bone. Mental health can’t be learned, only reawakened. It is like the immune system of the body, which under stress or through lack of nutrition or exercise can be weakened, but which never leaves us. When we don&39;t understand the value of mental health and we don&39;t know how to gain access to it, mental health will remain hidden from us.
(47) Our mental health doesn’t really go anywhere; like the sun behind a cloud, it can be temporarily hidden from view, but it is fully capable of being restored in an instant. Mental health is the seed that contains self-esteem - confidence in ourselves and an ability to trust in our common sense. It allows us to have perspective on our lives - the ability to not take ourselves too seriously, to laugh at ourselves, to see the bigger picture, and to see that things will work out. It’s a form. of innate or unlearned optimism.
(48) Mental health allows us to view others with sympathy if they are having troubles ,with kindness if they are in pain,and with unconditional love no matter who they are. Mental health is the source of creativity for soving problems, resolving conflict, making our surroundings more beautiful,managing our home life, or coming up with a creative business idea or invention to make our lives easier. It gives us patience for ourselves and toward others as well as patience while driving,catching a fish,working on our car,or raising a child. It allows us to see the beauty that surrounds us each moment in nature,in culture,in the flow of our daily lives.
(49) Although mental health is the cure-all for living our lives,it is perfectly ordinary as you will see that it has been there to direct you through all your difficult decisions.It has been available even in the most mundane of life situations to show you right from wrong,good from bad,friend from foe.Mental health has commonly been called conscience,instinct,wisdom,common sense,or the inner voice.We think of it simply as a healthy and helpful flow of intelligent thought .
(50) As you will come to see ,knowing that mental heath is always available and knowing to trust it allow us to slow down to the moment and live life happily.

Against a backdrop of drastic changes in economy and population structure, younger Americans are drawing a new 21st-century road map to success, a latest poll has found.

Across generational lines, Americans continue to prize many of the same traditional milestones of a successful life, including getting married, having children, owning a home, and retiring in their sixties. But while young and old mostly agree on what constitutes the finish line of a fulfilling life, they offer strikingly different paths for reaching it. Young people who are still getting started in life were more likely than older adults to prioritize personal fulfillment in their work, to believe they will advance their careers most by regularly changing jobs, to favor communities with more public services and a faster pace of life, to agree that couples should be financially secure before getting married or having children, and to maintain that children are best served by two parents working outside the home, the survey found.
From career to community and family, these contrasts suggest that in the aftermath of the searing Great Recession, those just starting out in life are defining priorities and expectations that will increasingly spread through virtually all aspects of American life, from consumer preferences to housing patterns to politics. Young and old converge on one key point: Overwhelming majorities of both groups said they believe it is harder for young people today to get started in life than it was for earlier generations.
While younger people are somewhat more optimistic than their elders about the prospects for those starting out today, big majorities in both groups believe those “just getting started in life” face a tougher a good-paying job, starting a family, managing debt, and finding affordable housing.
Pete Schneider considers the climb tougher today. Schneider, a 27-yaear-old auto technician from the Chicago suburbs says he struggled to find a job after graduating from college. Even now that he is working steadily, he said.” I can’t afford to pay ma monthly mortgage payments on my own, so I have to rent rooms out to people to mark that happen.” Looking back, he is struck that his parents could provide a comfortable life for their?children even though neither had completed college when he was young. “I still grew up in an upper middle-class home with parents who didn’t have college degrees,” Schneider said. “I don’t think people are capable of that anymore.”
One cross-generation mark of a successful life is_____.
A.trying out different lifestyles
B.having a family with children
C.working beyond retirement age
D.setting up a profitable business
It can be learned from Paragraph 3 that young people tend to____.A.favor a slower life pace
B.hold an occupation longer
C.attach importance to pre-marital finance
D.give priority to childcare outside the home
The priorities and expectations defined by the young will____.A.become increasingly clear
B.focus on materialistic issues
C.depend largely on political preferences
D.reach almost all aspects of American life
Which of the following is true about Schneider?A.He found a dream job after graduating from college.
B.His parents believe working steadily is a must for success.
C.His parents’ good life has little to do with a college degree.
D.He thinks his job as a technician quite challenging.
Both young and old agree that____.A.good-paying jobs are less available
B.the old made more life achievements
C.housing loans today are easy to obtain
D.getting established is harder for the young
