Quickly we made a hole in the bottom of it so that it could not be used 我们很快地在船底凿了一个洞让船不能再使用。
The dreamer , the joyous oarsman , lay on his back at the bottom of the boat , his heels in the air 那个梦悠悠、美滋滋的舟子四脚朝天，跌倒在船底。
By the time dog x reached ten weeks , our kids were more attached to him than barnacles to a boat ' s bottom 狗长到了10周，孩子们喜欢得不得了，狗对他们的吸引力比固定在船底上的甲壳动物的附着力还大。
Often , as i still lay at the bottom , and kept no more than an eye above the gunwale , i would see a big blue summit heaving close above me ; yet the coracle would but bounce a little , dance as if on springs , and subside on the other side into the trough as lightly as a bird 我躺在船底，睁开一只眼睛从船边向上望去，常常看到一个蓝色巨浪耸立在我的头顶，小艇纵身一跃滑向浪涡处，像装上了弹簧一般。
When we had carry d all these things on shore the oars , mast , sail , and rudder of the boat , were carry d away before , as above we knock d a great hole in her bottom , that if they had come strong enough to master us , yet they could not carry off the boat 船上的桨呀，桅杆呀，帆呀，舵呀等东西，早已经拿走了。所以，我们把剩下的这些东西搬上岸之后，又在船底凿了一个大洞。这样一来，即使他们有充分的实力战胜我们，也没法把小船划走。
The resistance of navigating vessel would be cut down and lead to the purpose of improving the velocity or decreasing the power of main engine while maintaining the velocity , if the technology of reducing the friction by microbubbles jetted from the bottom of vessels , which makes the water close to the vessel ' s bottom become the mixture or water and microbubbles and form a thin gas layer , could be applied in ships 如果把微气泡减阻技术应用到船舶上，在船舶底部喷射微气泡，使与船舶底部接触的水变成水与微气泡的混合液，形成一薄层气膜紧贴在船底表面，就可以达到提高航速或航速不变减小主机功率的节能目的。
While we were thus preparing our designs , and had first , by main strength heav d the boat up upon the beach , so high that the tide would not fleet her off at high - water - mark ; and besides , had broke a hole in her bottom , too big to be quickly stopp d , and were sat down musing what we should do ; we heard the ship fire a gun , and saw her make a waft with her antient , as a signal for the boat to come on board ; but no boat stirr d ; and they fir d several times , making other signals for the boat 首先，我们竭尽全力，把小船推到较高的沙滩上。这样，即使潮水上涨，也不致把船浮起来何况，我们已在船底凿了个大洞，短时间内无法把洞补好。正当我们坐在地上，寻思着下一步计划时，只听见大船上放了一枪，并且摇动旗帜发出信号，叫小船回去。
