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.

I am honored to have the chance to write for you. I have noticed that our school has very limited resources in term of students’ opportunities to do sports.
It is known to all what sports are very important to young people. If they have an access to good sports facilities, young people can adopt a healthy lifestyle and become more confident.
I suggest build a new playground, where should be designed for students with different interests. They should have a different section for each activity and available to students all year round. I believe so a sports area will meet our sporting needs.
Thanks for your reading.

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.

B. In fact, it can be done nearly anywhere, any time.
C. Therefore it requires very little helping equipment.
