1. Althugh this was banned in 1982, sme cuntries are still “murdering” these intelligent creatures withut mercy. 尽管早在1982年就已禁止, 但有的国家仍地无情地“谋杀”这些聪明的动物。 本句是一个复合句。sme cuntries are...是主句；althugh=thugh是从属连词，意为“虽然……;尽管……”，引导让步状语从句。
(1)用作连词表示“虽然”，两者大致同义，可换用，只是 althugh 比 thugh 更为正式。Thugh/Althugh it was raining, we went utside.(2)用作副词althugh一般不用作副词，而 thugh 可用作副词，且一般放在句末(不放在句首)，意为“可是；不过”。It’s hard wrk; I enjy it thugh.
(3)用于习语在 as thugh(好像，仿佛)、even thugh(即使，纵然)等固定短语中不能用 althugh。He is an hnest man, I must say, even thugh I dn’t like him.(4)用于倒装thugh引导的让步状语从句可用部分倒装的形式(注意：倒装后位于句首的名词之前不用冠词)，但 althugh 一般不这样用。Child thugh he was, he did quite well.

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 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 supprt cean explratin.
