China has the【1】 (distinct) of respecting the aged and cherishing the young. Contrary to popular belief, however, older people generally do not want to live with their children.

According to the latest 【2】 (analyze), about 80% of people 65 years and older have frequent contact with their children. About 75% of elderly parents 【3】 don't go to nursing homes live within 30 minutes for the sake of 【4】 (convenient).

However, 【5】 (mere) having contact with children does not guarantee happiness in old age. So far, some researchers 【6】 (find) that people who are most associated with their families have the lowest spirits. So it is more likely 【7】 poor health, not just family involvement, deepens spirits.

【題目】"Everybody is a genius.But if you judge a fish by its ability to climb a tree,it will live its whole life believing that it is stupid."—Albert Einstein

If you have a kid with special needs in the school system,chances are you have come across that saying hanging on a classroom wall.My five-year-old daughter Syona has cerebral palsy（腦癱）and it means,combined with her communication and sight problems,that normal standard isn't always an accurate measure of her abilities.

By now you have probably heard about Chris Ulmer,the 26-yearold teacher in Jacksonville,Florida,who starts his special education class by calling up each student individually to give them much admiration and a high-five.I couldn't help but be reminded of Syona's teacher and how she supports each kid in a very similar way.Ulmer recently shared a video of his teaching experience."I have seen their confidence increase rapidly."he said.All I could think was: how lucky these students are to have such good teachers.

Syona's teacher has an attitude that can best be summarized in one word: awesome.Her teacher doesn't focus on what can't be done—she focuses on what can be done.Over the past several months,my husband Dilip and I have seen Syona's confidence increase tenfold.She uses words she wouldn't have thought of using before.She recently told me about her classmate's trip to Ecuador and was very proud when I understood her on the first try.

I actually wonder what the influence would be if we did something similar to what Ulmer does with his students in our home.We've recently started our day by reminding each other of the good qualities we all possess.If we are reminded of our strengths on a regular basis,we will become increasingly confident about progress and success.

【1】What does the author think of Albert Einstein's saying?

A. Funny. B. True.

C. Strange. D. Confusing.

【2】What can we learn about Syona's teacher?

A. She is Syona's favorite teacher.

B. She puts Einstein's quote on the wall.

C. She uses videos to teach her students.

D. She helps increase her students' confidence.

【3】Why did Syona feel proud in the third paragraph? .

A. Her mother knew what she expressed.

B. Her progress was appreciated by her parents.

C. She had developed a positive attitude.

D. She had been to Ecuador with her classmate.

【4】What change has taken place in the author's family?

A. They've invited Ulmer's students to their home.

B. They visit Ulmer's classroom regularly.

C. They give each other praise every day.

D. They feel grateful to people in their lives.

【題目】A Samoan airline says that it is the world’s first carrier to charge passengers by their weight. Samoa Air, which opened in 2012, asks passengers to give their personal weight during booking, which is then charged according to the length of a flight. The customers will also be weighed just before they board the plane.

"It is believed that all people throughout the world are the same size," Samoa Air CEO Chris Langton said. "Airplanes always run on weight, not seats."

"There is no doubt in my mind that this is the concept of the future. This is the fairest way of your travelling with your family or yourself."

Though the airline introduced the plan last November, it caught people's attention last week when the carrier began international flights to neighboring American Samoa.

Almost at the same time, a Norwegian economist, Bharat Bhatta, published a report suggesting that airlines should charge obese passengers more.

The Pacific Islands contain some of the world’s most common countries for obesity, many ranking in the top 10, according to the World Health Organization (WHO). Samoa is ranked number four, with 59.6 percent of the population considered obese, said the most recent WHO report.

According to Samoa Air's latest schedule, the airline charges up to $0.57 per kg for flights in Samoa and $1.03 per kg for its only international flight to American Samoa, around 250 miles.

Children under 12 are charged 75 percent of the adult rate, with fares also based on weight. Any overweight baggage is calculated at the same rate as the passenger's personal weight.

The plan could actually prove cheaper in some cases, such as for families travelling with small children, and Langton said customer reaction has mainly been "amazingly positive".

The idea of charging passengers by weight has been hotly discussed before, and in the US some airlines require those who do not fit into a seat comfortably to buy a second seat.

【1】What does the underlined word "this" in Paragraph 3 refer to?

A. Airlines should charge passengers by flight length.

B. All people throughout the world are the same size.

C. It is unfair to weigh passengers at the airport.

D. Airplanes always run on weight, not seats.

【2】In Bharat Bhatta’s eyes, Samoa Air's plan might be _______.

A. funny B. acceptable

C. strange D. disappointing

【3】A 100 kg adult flying to American Samoa would be charged _______.

A. $57 B. $75

C. $103 D. $125

【4】What does the text mainly tell us?

A. 59.6% of Samoans are considered obese.

B. Samoa Air introduces pay-by-weight pricing.

C. Airlines should charge obese passengers more.

D. Baggage must be calculated as passengers’ weight.
