Living near the ocean is good for health, but not a luxury all can afford. But those who can, certainly gain a lot of health benefits over common inland folks.

● 【小题1】 As we know, because people living near a coast get enough time to swim in the seawater, they naturally tend to be stronger. Physicians have been recommending visits to coasts that specialize in providing seawater cleansing treatment, which improves the immune system.

● Living near the ocean promotes physical activity. The seashore encourages outdoor activities like jogging on the sand, beach volleyball, scuba-diving, surfing, etc .【小题2】

● Fresh air helps get sleep. Fresh ocean air is composed of negatively charged ions that enable us to consume oxygen, adding to good health. These ions also aid in balancing the serotonin (血清素) level, which helps in feeling more relaxed. 【小题3】 Little by little, this leads to better sleep after spending a large amount of time near the ocean.

● Living near the ocean can help you absorb more vitamin

Jumping spiders (跳蛛) are vital for agricultural pest control, and 【小题1】 species can even learn to distinguish (辨别) the color red in their prey (猎物), a 2015 study 【小题2】 (show). They are able to learn to associate this color 【小题3】 poisonous prey and avoid it or find out high-quality prey.

Jumping spiders will eat almost any small pest, 【小题4】 (range) from caterpillars to flies. Not only does this 【小题5】 (natural) reduce the amount of agricultural damage from insect pests, but it means farmers can avoid using chemical treatments 【小题6】 (protect) their crops.

In total, a large number of jumping spiders, over 5,000 species, 【小题7】 (find) on every continent except Antarctica by now. Being able to adapt to the environment is a key evolutionary skill. Since the spiders are able to distinguish 【小题8】 foods are nutritious, from those that are 【小题9】 (harm). They can stay alive longer and manage a wide 【小题10】 (various) of pests.

   The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子）in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!
