This is not a diet. It’s a simple way to lose weight. And you don’t even have to give up the food you love or join a gym. You just follow some habits that thin people have. Keep them, and you’ll become thin.
(1) Wake-up
When you wake up in the morning, sit up slowly without using your hands. With legs straight out, bend forward until you feel sore in your back. It will burn about 10 calories.
(2) Start with soup
When you have a meal, order a clear soup, and have it before having the main food. In this way, you’ll feel fuller, so you’ll eat less when the main food comes.
(3) An apple ( or more) a day
Apples are full of fiber and water, so your stomach will want less. The study shows that people who eat at least three apples a day lose weight.
(4) Stand up and walk around
Every time you use the mobile phone, stand up and walk around. Heavy people sit on average two and a half hours more each day than thin people. This skill is very important as standing up and walking around will burn 50 or more calories.
Use these skills, and you will have a big weight loss.
Which of the following may the author disagree

A:Sitting up slowly without using your hands helps burn calories. B:Eating apples every day is good for people’s health. C:You have to join a gym if you want to lose weight. D:It’ s good to walk around while talking on the mobile phon

More and more people like bicycling and it is no surprise. It is fun, healthy and good for the environment. Maybe that’s why there are 1.4 billion bicycles and only 400 million cars on roads worldwide today. Bikes can take you almost anywhere, and there is no oil cost!

To understand how astrology works, we should first take a quick look at the sky. Although the stars are at enormous distances, they do indeed give the impression of being affixed to the inner surface of a great hollow sphere surrounding the earth. Ancient people, in fact, literally believed in the existence of such a celestial sphere. As the earth, spins on its axis, the celestial sphere appears to turn about us each day, pivoting at points on a line with the earth’s axis of rotation. This daily turning of the sphere carries the stars around the sky, causing most of them to rise and set, but they, and constellations they define, maintains fixed patterns on the sphere, just as the continent of Australian maintains its shape on a spinning globe of the earth. Thus the stars were called fixed stars.
The motion of the sun along the ecliptic is, of course, merely a reflection of the revolution of the earth around the sun, but the ancients believed the earth was fixed and the sun had an independent motion of its own, eastward among the stars. The glare of sunlight hides the stars in daytime, but the ancients were aware that the stars were up there even at night, and the slow eastward motion of the sun around the sky, at the rate of about thirty degrees each month, caused different stars to be visible at night at different times of the year.
The moon, revolving around the earth each month, also has an independent motion in the sky. The moon, however, changes its position relatively rapidly. Although it appears to rise and set each day, as does nearly everything else in the sky, we can see the moon changing position during as short an interval as an hour or so. The moon’s path around the earth lies nearly in the same plane as the earth’s path around the sun, so the moon is never seen very far from the ecliptic in the sky. There are five other objects visible to the naked eye that also appear to move in respect to the fixed background of stars on the celestial sphere. These are the planets Mercury, Venus, Mars, Jupiter, and the Saturn. All of them revolve around the sun in nearly the same plane as the earth does, so they, like the moon, always appear near the ecliptic. Because we see the planets from the moving earth, however, they behave in a complicated way, with their apparent motions’ on the celestial sphere reflecting both their own independent motions around the sun and our motion as well.

A:the earth was spinning on the axis of the sky B:the sky was a hollow sphere spinning around the earth C:the patterns of stars on the sky would never change D:the stars around the sky were not stationary
