Organic exercise is a good fit for people looking to train functionally. It is defined as exercise that is similar to the type of physical activity performed by ancient hunter-gatherer ancestors. Organic exercise is generally preformed in natural or outdoor settings. 1.Organic exercise may include such activities as walking, jogging, swimming, hiking or rock climbing.

When it comes to organic exercise, one of its most significant benefits is its limited reliance on equipment. 2.Going for a jog, walking, or even hiking does not require tools, weights, or even hiking does not require tools, weights, or other products, and therefore, is fairly inexpensive.

Since the types of activity emphasized in organic exercise programs are similar to those performed as part of daily life, they do not require extensive or long amounts of practice to obtain proficiency(精通). 3.Therefore the type of activity recommended in an organic workout routine can be performed by beginning or advanced exercisers alike with relative ease.

While the type of exercise recommended in an organic workout may be easy enough to perform, the intensity at which it is recommended can be too much for some individuals. 4.Individuals who are new to exercise or suffer from a chronic health condition that limits their physical ability may find it difficult to perform exercise that is especially strenuous.

5.Individuals who are new to exercise may want to talk with their health care provider before choosing this type of activity. In some cases, it may be better to start off with a more traditional workout and slowly transition to organic exercise than starting with this regimen(养生法)right off the bat.

A. Weigh both the benefits and drawbacks.

B. In fact, it can be done nearly anywhere, any time.

C. Therefore it requires very little helping equipment.

D. Choosing the right types of organic exercise is important.

The next time someone asks you where the biggest ocean is, point them toward Jupiter. While earth harbours about 320 million cubic miles(1,333 cubic km)of water, our planet is practically a desert compared to the rest of the Solar System.

A moon of Jupiter called Europa, for example, which is roughly the size of our own Moon, likely hides a subsurface ocean with more than twice as much water as there is on Earth.

Yet even that pales into insignificance in comparison to Europa's neighbour Ganymede; more than 30 times as much water as our home planet is thought to reside there as liquid and ice.

And scientists keep finding more water wherever they look. On September 28, researchers reported that Dione — a small moon of Saturn — probably has a subsurface ocean, too.

To see just how Earth stacks up against other ocean worlds, Business Insider contacted Steve Vance, a planetary scientist at NASA's Jet Propulsion Laboratory who's calculated the numbers on just how much water might be out there.

In order of how much water they have, from the least to the most, they are: Enceladus, Dione, Earth, Europa, Pluto, Triton, Callisto, Titan, and Ganymede. Mimas, a moon of Saturn, and Ceres, the largest asteroid in the Solar System, are also thought to have subsurface oceans —but scientists aren't yet sure how big each one might be.

1.How many stars are mentioned in this passage?

A. Eleven. B. Twelve.

C. Thirteen. D. Fourteen.

2.What can we know according to the passage?

A. Compared with the Solar System, Jupiter looks as if it is a desert.

B. Ganymede is thought to be covered with more water than Europa.

C. Business Insider is a planetary NASA’s laboratory of Steve Vance.

D. Ceres harbours the largest subsurface ocean in the Solar System.

3.What does the passage mainly tell us?

A. The order of how much water the stars have has been figured out.

B. Scientists keep exploring more water in the universe wherever they look.

C. These ocean worlds reveal just how little water we have on Earth.

D. NASA’s planetary scientists are calculating the water numbers in the sky.

Got big plans for Friday night? That’s OK, we don’t either.

Guess we’ll all have to make do by watching the celestial (天空的)show that will take place that night.

First, there will be a full moon. That’s always fun, but this one will be a little more special. It’s known as a “snow moon.” The name comes from the fact that the heaviest snows usually fall during February, according to the Old Farmer’s Almanac.

But if that’s not special enough, there’s also an eclipse (月食)that night. It’ll be a penumbral lunar eclipse, meaning ifs a partial eclipse that leaves sections of the moon darkened by the earth’s shadow. No, it won’t be as spectacular as those “blood moon” eclipses. It’ll be subtler. The level of darkness it reached during the eclipse may or may not be apparent; it just depends on where you are when you view it.

In North America, the eclipse begins at 5:34 p.m. ET and ends at 9:53 p.m. ET, according to astronomy website EarthSky. The eclipse will be at its height around 7:44 p.m. ET.

If that’s still not enough, let’s throw in a comet (彗星)to the night’s festivities.

Comet 45P (it has a much longer name, but we won’t burden you with it here) is visible as it flies by Earth. The comet will get within 7.4 million miles of the planet as it makes its closest approach this weekend, according to Universe Today.

Comet 45P will be the most visible a couple of hours after the eclipse, so look to the skies again around 3 a.m. ET Saturday and find the greenish-blue light with a tail.

And don’t forget, a total big-time solar eclipse will streak across the United States on August 21st.
