Then finally, we shared ur infrmatin with ther whale research grups arund the wrld.B：It all sunds s wnderful! I wish I culd have jined yu.A: I d, t.
Watching and Talking
Watch the vide Prtecting Bidiversity and then talk with yur partner and make a plan fr a trip t see the animals.
Fr ur trip, we wuld like t g t the Shanghai Ocean Aquarium. We can first visit the special exhibitin f saving sharks. Then we can g t see the seahrses whse number declined greatly fr the past decade. Hwever, mst peple d nt knw much abut seahrses at all. I think we need t raise awareness abut seahrses and marine cnservatin in China. The last spt will be The Chinese Pavilin, which displays the aquatic rganisms and bi-system in the Yangtze River and sme natinal endangered rare aquatic creatures, like Chinese alligatr and Chinese Sturgen.

Sample Writing
Even thugh the ceans make up abut 70% f the earth's surface, mre than 80% f the ceans remain unexplred. While sme peple say that we shuld nt explre the ceans, their reasning is nt very sund. Explring is nt the same as expliting. When we explre a place, we g just t see and understand what is there.We shuld explre the cean, first and fremst, because we d nt knw what we d nt knw. We thught we knew many abut the cean, but we were wrng. There culd be life frms in the cean,
fr example, that fit nne f the neat categries we have fr life while we have n clue that they even exist.This brings up the secnd pint. We already knw many things abut the cean, but we need t learn mre. A gd example is cean acidificatin. We knw that it is causing cral t die. We knw that using less fssil fuel wuld cause the prcess t slw dwn. Hwever, we need t learn mre t find ut hw t stp it. We need mre research t see what is ging n, and t cme up with plans and slutins.Finally, t d this research, we have t enter an extreme envirnment nt very friendly t humans.
This requires the develpment f new technlgies that can als benefit us in ther areas. Fr example, in many ways, the deep cean resembles uter space. The technlgies can benefit each ther. Fr anther instance, the technlgy f a mechanical arm t cllect samples with has been used in factries and develpment f artificial limbs fr humans.All in all, there are many gd reasns t explre the ceans. If we care abut science, abut prtecting ur ceans, and abut develping new technlgies, we need t d all we can t supprtcean explratin.

The Imprtance f Prtecting Our Oceans As we all knw, there are varieties f resurces under the sea. Hwever, the past ten years has witnessed that sme creatures have died ut. Therefre, marine pllutin has been greatly cncerned by the whle wrld.
On the ne hand, we must make peple realize the imprtance f prtecting the cean. As a matter f fact, t prtect the cean is t prtect human beings. On the ther hand, the gvernment shuld take immediate measures t keep the balance f nature. In n way shuld we abandn prtecting the envirnment.
