Group exercise is one of the most effective ways to improve physical fitness and sustain (保持) a healthy lifestyle.Group exercise is challenging, yet fun and empowering! Of course everyone knows that exercise is good for the body.However, studies have shown that when exercise is performed in groups, it's not only great for improving physical health but for psychological health.It's an opportunity to be social, release endorphins (内啡肽), and improve your strength.Additionally, group exercise creates a community feel and the shared common goal motivates participants to work hard.The instrumental support of taking on a fitness journey with others proves more effective than going to the gym alone.

Another beneficial aspect of group exercise is the informational support participants receive from the instructor.Many people fear the gym because they feel lost and don't want to embarrass themselves.If you feel you can relate, then group training is an even better option for you.It's a great opportunity to learn more about fitness through the clear instruction and supervision (监管) of a fitness instructor.If you're tired of wandering around the gym wasting time and becoming bored, you can attend an upbeat group fitness class that'll keep your workout on track.Don't let fitness frighten you!

If you're serious about wanting to live a healthy lifestyle, it's extremely important to surround yourself with people who'll provide you with the proper emotional support.I wouldn't scold anyone for deciding to party on weekends and in turn I wouldn't expect anyone to give offense to me for focusing on my health.Surround yourself with people who uplift, encourage and understand you! Make fitness even more fun by trying something new or any group fitness class, with a friend.Plan to go for a jog together.Then try a fun healthy restaurant or fresh juice bar! Fitness can be both fun and social!

Surrounding yourself with people who'll provide you with respect and support can be very beneficial while working towards reaching health and fitness goals.First, decide to do it for yourself and work towards staying positive.Then make sure the people you surround yourself with are supportive.Don't let negativity ruin your motivation.

【主旨大意】本文介绍团队锻炼在健身和保持健康生活方式方面的益处。 1．【答案】A

【解析】词义猜测题。根据本句中的“bored”与“keep your workout on track”可知，upbeat意思与cheerful相近，意为“快乐的；积极向上的”。故选A项。

2．【答案】D

【解析】细节理解题。根据第三段首句中的“…it's extremely important to surround yourself with people who'll provide you with the proper emotional support”可知，让能为你提供合适的情感支持的人在你周围非常重要，故选D项。

3．【答案】B

【解析】主旨大意题。综合全文可知，文章介绍“团队锻炼在健身中的积极作用”，因此B项“辅助性的健康(运动)”概括得最全面。

One in five people carry a ‘smart gene’ variant(变体)linked to long lifespan, bigger forebrain and enhanced mental ability, researchers have found.

“We've known for a long time that people lose cognitive(认知) abilities as they age, but now we're beginning to understand that factors like KLOTHO can give people a boost in aging.Genetic variation in KLOTHO could help us predict brain health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer's disease(老年痴呆症)，” said senior author, Dena Dubal of University of California.

The KLOTHO gene affects a protein found in the kidneys and the brain that regulates many different body processes.About one in five people carry a single copy of the varian, known as KL-VS，which boosts levels of the protein and is associated with a longer lifespan and improved heart and kidney function.A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan.

In the new study scientists scanned the brains of 422 men and women aged 53 and over who

were also tested for the KLOTHO gene.They found that participants with a single copy of the gene variant also had a larger brain region known as RDLPFC, which is especially likely to shrink with age.Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time.

Researcher Dr Jennifer Yokoyama said, “The brain region enhanced by genetic variation in KLOTHO is vulnerable(脆弱的)in aging and some mental disease.In this case, bigger size means better function.It will be important to determine whether the structure increase associated with carrying one copy of KL-VS can offset the cognitive shortage caused by disease.”

People who have one copy of a variant KL-VS tend to live longer and have lower chances of suffering a stroke (中风)，whereas people who have two copies may live shorter lives and have a higher risk of stroke.

( )4.What can we learn from the second paragraph

A．People's cognitive abilities do not decline if people have KLOTHO.

B．With the clear understanding of KLOTHO, Alzheimer's disease can be cured now. C．Genetic variation in KLOTHO could be helpful in treating mental disease in elderly people. D．Genetic variation in KLOTHO could lead people to suffer from Alzheimer's disease. ( )5.If a person carries two copies of the gene variant, he/she may ________. A．have better kidney function B．have a shorter lifespan

C．have a higher level of the protein in his/her body D．suffer from some cognitive disease

( )6.The reason why older people's attention is easily distracted may be that ________. A．they have fewer neurons in the RDLPEC B．their brain region is too large

C．they have two copies of the gene variant D．they have more neurons in the RDLPEC

( )7.What does the underlined word “offset” in Paragraph 5 probably mean A．Prevent. C．Keep.

B．Balance. D．Promote.

【主旨大意】研究发现有五分之一的人携带有与长寿、较大前脑和更强的心智能力的“聪明基因”的变体。本文研究了KLOTHO中变体与人衰老和精神疾病的关系：大脑区域越大，功能越强。

4．【答案】C

【解析】事实细节题。根据第二段“Genetic variation in KLOTHO could help us predict brain

health and find ways to protect people from the diseases that happen to us as we grow old, like Alzheimer's disease(老年痴呆症)”可以推知KLOTHO中的基因变体对于预防和治疗老年人疾病的意义。可以得知选项C符合题意。

5．【答案】B

【解析】细节理解题。根据第三段“A small minority, 3% of the population, has two copies, which is linked to a shorter lifespan”可以得知选项B符合题意。

6．【答案】A

【解析】推理判断题。根据第四段“Loss of neurons in this area may be one reason why older people are sometimes easily distracted and find it difficult to do more than one task at the same time”可以推知RDLPEC中神经元的损失会导致人注意力分散和很难在同一时间做多个任务，可以得知选项A符合题意。

7．【答案】B

【解析】词义猜测题。 根据倒数第二段上下文可以得知在KLOTHO中由于基因变体增大的大脑区域很容易衰退或产生精神疾病，所以较大的大脑区域功能更强。携带KL-VS一副与大脑结构是否增加对于平衡由疾病导致的认知确实很重要。可以得知选项B符合题意。
