Looking for a new weight loss plan? Try living on top of a mountain. Mountain air contains less oxygen than air at lower altitudes, so breathing it causes the heart to beat faster and the body to burn more energy. A handful of studies have found that athletes training at high altitudes tend to lose weight. Doctor Florian Lippl of the University Hospital Of Ludwig-Maximilians-university Munich wondered how the mountain air would affect overweight individuals if they weren’t doing any more physical activity than usual.
Lippl and his colleagues invited 20 overweight men to an environmental research station about 300 meters below the summit of Zugspitze, a mountain around 2,970 meters near the Austrian border. They were allowed to eat as much as they liked. The men also gave blood so that researchers could test for hormones linked to appetite and fatness. At the end of the week, the men, whose mean weight starting out was 105kg, had lost on average about l.5kg. The men’s blood pressure also dropped, which the researchers believed was due to weight lost.
Exactly what caused the weight loss is uncertain. Loss of appetite is common at higher altitudes, and indeed the men ate significantly less than usual—about 700 calories fewer per day. Lippl also notes that because their consumption was being recorded, they may have been more self-conscious about what they ate. Regardless, eating less accounts for just l kg of the l.5 kg lost, says Lippl. He thinks the increased metabolic (新陈代谢的) rate, which was measured, also contributed to weight loss but cannot separate the different effects with the given data.
Appetite loss at high altitudes could certainly be key, notes Damian Bailey, a physiologist at the University of Glamorgan, UK, who recently lost 11 kg during a 3-month expedition to the Andes in Chile.
Unfortunately, for the average person there is no treatment that can resemble living at high altitude, says Lippl. The only alternative is hypobaric chamber, which exposes subjects to low oxygen and isn’t practical as a treatment. He says, half- jokingly, “If fat people plan their holidays, they might not go to the sea, but maybe to the mountain.”

_____Susan is a big eater. She usually has a lot at every meal. So she wonders whether she could only eat less for the first meal of a day to lose weight.
_____Tina is a fat girl who doesn’t like exercise much. She just wants to lose weight by eating less but not doing exercise.
_____Maggie is a busy office lady. She usually has to work overtime every day. So she could only have her dinner late at night. She wants to be slimmer so that she could be much more attractive.
_____ Judy is a fashionable designer. She hopes to have a slim shape as models. She usually doesn’t have any regular meal, but has some snacks when she is hungry.

A．If you eat less for breakfast, you have a lower chance of losing weight. Breakfast is important. It gives the body sufficient energy to sustain itself through the morning, and it also stimulates metabolic (新陈代谢) activity in the body. Metabolism is what consumes fat and what makes us slimmer. So, don’t forget to eat something for the breakfast.

B．If you ate your last meal right before going to bed, the calories accumulated from this meal could be twice the amount accumulated from a same meal if you ate it another time during the day.

C．Many people stop doing exercise when they eat less. When you do this, your body will burn less fat. So even if people take in less calories, they get rid of less too. The balance is then unchanged.

D．People gain fat not from the food they eat, but from the number of calories in the food. For example, a bunch of vegetables has just one tenth the calories contained in a small bit of chocolate cake. So make sure you have adequate regular meals, but firmly say no to various snacks, milk tea or even instant noodles.

When Frida Kahlo's paintings were on show in London, a poet described her paintings as “ a ribbon （丝带）around a bomb”. Such comments seem to suggest Kahlo had a big influence on the art world of her time. Sadly, she is actually a much bigger name today than she was during her time.
Born in 1907 in a village near Mexico City , Kahlo suffered from polio（小儿麻痹症）at the age of seven. Her spine （脊柱）became bent as she grew older. Then, in 1925, her back was broken in several places in a school-bus accident. Throughout the rest of her life, the artist had many operations, but noting was able to cure the terrible pain in her back. However, the accident had an unexpected side effect. While lying in her bed recovering, Kahlo taught herself to paint.
In 1929, she got married to Diego Rivera, another famous Mexican artist. Rivera’s strong influences on Kahlo’s style can be seen in her early works, but her later works from the 1940s, known today as her best works, show less influence from her husband.
Unfortunately, her works did not attract much attention in the 1930s and1940s, even in her home country. Her first one-woman show in Mexico was not held until 1953. For more than a decade after her death in 1954, Kahlo’s works remained largely unnoticed by the world, but in the 1970s her works began to gain international fame at last.
What does the phrase “a much bigger name” in paragraph 1 most nearly mean?

A．a far better artist	B．a much more famous person
C．a much stronger person	D．a far more gifted artist

The terrible pain Kahlo suffered was caused by.

B．Encouragement

C．Worry

D．Sympathy（同情）

I moved to the small, busy town of Edison in New Jersey six years ago. It was during the second term of my fifth grade. My parents got new jobs and higher income, so they decided it was time to move from Woodbridge to a better, more educational town.
In the US, it is unnecessary to take a test to get into a “good” middle or high school. You just attend the school close to where you live. So, many parents will think about the quality of the local school when they decide to buy a new house. My parents did the same. We finally chose Edison mainly because of the high quality of its school.
In New Jersey, an area with a good school usually means a concentration of Asian people. There are about 300 students in our school. 55% are Asians and just under half of that are Chinese. There are so many Chinese people nearby that we even have our own Chinese school.
Edison is an old town, just like thousands of others in the United States. However, I have treated it as my hometown. That’s where I spend much of my youth, and the memories there can’t be moved anywhere else.
Why did the writer’s parents move to Edison?

A．Because they were born there.	B．Because it was a better educational town.
C．Because the writer began his fifth grade.	D．Because the writer didn’t need to take a test.

How many students are from Asia in the writer’s school?

A．About 80.

B．About 160.

C．About 220.

D．About 300.

What does the underlined expression “a concentration of” mean in Paragraph 3?

A．None of.

B．The whole of

C．A large number of

D．A small number of

Why can’t the writer forget Edison?

A．Because he regards it as his hometown.	B．Because his parents got new jobs there.
C．Because there are many Asians there.	D．Because it is in the state of New Jersey.

The following diaries were written by an Australian boy named Tony. He was on holiday with his family in South Asia.
