Could Organizing Your Home Change Your Life?

Marie Kondo is an expert on organizing and cleaning. She is considered an expert on clearing away unused or unnecessary things, better known as clutter. Actually, she did write a book on the issue, which is called “The Life-Changing Magic of Tidying Up”. 【1】 It has sold more than 2 million copies.

Marie Kondo says people can improve their lives by changing the way they think about all their stuff-- everything from books, documents and photographs to clothing and personal mementoes. 2 And this is pretty good.” Ms. Kondo writes.

This is not the first time an organizing expert has written a book on clutter. Other books suggest wonderful things will happen when you organize your home. One book says that if you throw out 50 things from your home, you will actually find your life 3 And still others promise a better job, more money and a perfect family if you simply organize the things that fill your life. 4 She told the Business Insider website that some of her clients have lost weight. “Your self-perception is improved by living in a clean and neat room,” she said. “This can change lifestyles and, in turn, appearances.”

Marie Kondo teaches a method of organizing she calls KonMari. It is more of an event or ceremony. This is the part that followers say makes it more lasting. Ms. Kondo says KonMari creates a different relationship between you and your possessions. If the object meant something to you or served you well, you thank it for its service before throwing or giving it away. In her book, Ms. Kondo suggests that you touch the item and ask one simple question: "Does it bring me joy?" 5

If it doesn’t, you give it away so that it may give joy to someone else.

A. Her book is a best-seller around the world

B. Marie Kondo makes some of the same claims

C. On the contrary, Marie Kondo disagrees with it.

D. Unnecessary things just take up too much space in your home.

E. If it doesn’t, you give it away so that it may give joy to someone else.

F. Another book says that if you make clutter disappear, you will also lose weight.

G. When you put your house in order, you put your affairs and your past in order too.

【题目】阅读下列短文,从每题所给的四个选项(ABCD)中,选出最佳选项。

It’s a time when school,homework,active social lives and pare-time jobs keep teenagers busy from early in the morning until late at night.They are likely to try to make up for a lack of sleep by “sleeping in” on the weekends.Unfortunately,this causes irregular sleep and actually makes the problem worse.

Most teenagers are not able to fall asleep until late at night.Since many teens aren’t sleepy until around 11 pm.but need to be at school by 7:30 or 8:00 am .They cannot get enough sleep .During puberty(青春期),the biological clock in the brain naturally re-sets to a later time ,and this causes teens to fall asleep later.Then ,when it’s time to get up ,a teen’s body clock is likely to still be producing the night-time hormones .This makes it hard for them to feel active and energetic in the morning.

A growing body of research suggests that starting high school later improves attendance,achievements and grades.A few years ago in an important study ,test scores on the SAT college entrance exams in Edina,Minnesota jumped more than 100 points on average,when the morning school bell rang an hour later.Unfortunately,most schools are not set up to start later and fail to satisfy teen’s sleep needs.

【1】What effect does “sleeping in” on the weekends have on teenagers?

A.Improving their health

B.Weakening their energy

C.Disturbing their biological clock

D.Making up for their hormone loss

【2】The study in Minnesota shows that starting morning school one hour later helps to______.

A.make teenagers grow faster

B.change teenagers’ sleep needs

C.do more research on teenagers

D.improve students’ achievements

【3】The text helps us to know more about teenagers’______.

A.daytime activities B.sleeping habits

C.mental problems D.studying methods

【题目】One in five people carry a ‘smart gene’ variant(变体)linked to long lifespan, bigger forebrains 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.

【1】 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

【2】If a person carries two copies of the gene variant, he/she may _______

A. have better kidney funtciton

B. have a shorter lifespan

C. have a higher level of the protein in his/her body

D. suffer from some cognitive disease

【3】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

4What does the underlined word “offset” in Paragraph 5 probably mean?

A. Prevent

B. Balance

C. Keep

D. Promote
