A trawler is a fishing boat that catches fish by dragging a big bag-shaped net, called a trawl, slowly through the water behind it. That dragging is what makes it a trawler rather than any other fishing boat — boats that use lines, or that sit and wait with nets, get other names.

A trawler拖網漁船 is a fishing boat that catches fish是一種靠這樣捕魚的漁船，by dragging a big bag-shaped net, called a trawl拖著一個袋狀的大網（這種網叫trawl），slowly through the water behind it在船後面的水裡緩慢拖行。That dragging is what makes it a trawler rather than any other fishing boat就是這種「拖」的動作，讓它是trawler而不是別種漁船——boats that use lines, or that sit and wait with nets, get other names用釣線的船，或是放網等魚上鉤的船，會有別的名字。

Trawlers range from small family boats working near the coast to huge factory ships that stay at sea for weeks and freeze the catch on board. Because of that, the word often turns up in news about fish stocks and sea damage, sometimes with a sad or angry tone, since a heavy net dragged along the seabed destroys a lot.

Trawlers range from small family boats working near the coastTrawlers從在近海作業的小型家庭漁船，to huge factory ships that stay at sea for weeks and freeze the catch on board到能在海上待好幾週、把漁獲直接冷凍在船上的大型工廠船都有。Because of that正因如此，the word often turns up in news about fish stocks and sea damage這個字常出現在講魚群數量和海洋破壞的新聞裡，sometimes with a sad or angry tone有時候語氣還帶著哀傷或憤怒，since a heavy net dragged along the seabed destroys a lot因為一張沉重的網在海床上拖行，會破壞掉很多東西。

You will also see the word in stories about the sea and about war — old trawlers were often taken by navies to sweep mines, because they were already built to drag things.
