用例

<template>
  <div>
    <sgGoogleTranslate />
    <br><br>
    <p> 我一路向北，离开有你的季节，你说你好累，已无法再爱上谁。风在山路吹，过往的画面全都是不对，细数惭愧，我伤你几回。 </p>
    <br>
    <p> 我想我是太过依赖，在挂电话的刚才，坚持学单纯的小孩，静静看守这份爱，知道不能太依赖，怕你会把我宠坏，你的香味一直徘徊，我舍不得离开。 </p>
    <br>
    <p> 缓缓飘落的枫叶像思念，为何挽回要赶在冬天来之前，爱你穿越时间，两行来自秋末的眼泪，让爱渗透了地面我要的只是你在我身边。 </p>
