一道阅读题One potential problem is that opening the mouth to breathe detracts from the streamlining of these fishes and tends to slow them down.Some species of tuna have specialized grooves in their tongue.It is thought that these grooves help to channel water through the mouth and out the gill slits,thereby reducing water resistance.8.The word channel in the passage is closest in meaning to ○Reduce ○Remove ○Direct○Provide 为什么选direct啊 Remove不行吗?后面不是说through the mouth and out the gill slits 英语

【答案】 这是托福题吧 答案应该是3 Direct 这里的channel的意思是疏导,grooves help to channel water through the mouth and out the gill slits的意思是鳞沟有助于将水从嘴里引导到鳃缝外 在这4个选项中 只哟direct有引导这个意思.
