答案：
(答案→)C
解析：本文为记叙文。养了十几年的心爱的宠物狗被药毒死了。然而，因为继父的隐瞒，作者在一周后才得知这一消息。作者满怀的悲伤化作了对继父的愤懑，是妈妈的一句话让作者明白了一个永生难忘的道理。
【小题1】答案：C狗肚子里长了肿瘤，自然是非常疼痛。
【小题2】答案：A有时候，散步的途中，它总是趴在地上，一步也迈不动了。情态动词would这里表示某种倾向或习惯性动作，意思是“总是……”。
【小题3】答案：B此处指饱受病痛折磨的狗步履艰难。
【小题4】答案：D与其说它是宠物，不如说它更像是我的姐妹。
【小题5】答案：D这里指狗已经死去的事实(truth)。plan计划；accident事故；anecdote逸事，趣闻。
【小题6】答案：B因为种种原因，继父将狗死去的消息推迟一周之后才告诉我们，故选项中只有B符合语境。wait推迟，延缓；lie说谎；reflect反映；hesitate犹豫，不情愿。
【小题7】答案：A因为继父没有告知实情，我以为狗仍然在动物医院里。
【小题8】答案：C这里指萦绕在我脑海中的各种想法。fact事实，真相；opinion意见；doubt怀疑，疑惑。
【小题9】答案：C出于对我的保护，家人习惯于对我隐瞒真相。have a habit of doing sth.有做某事的习惯。
【小题10】答案：D根据上文可推断出，我知道姨妈患癌症是在姨妈的身体已恢复之后。
【小题11】答案：B根据下文可推知，我试图求助于妈妈，发泄对继父的不满。turn to sb.求助于某人；adjust to 适应，调节；contribute to 为……做贡献；relate to 与……有关，涉及。
【小题12】答案：A第二段第三句中But I was also angry at my stepfather以及下文的Im so angry with Steve都提示这里应该选择A项。
【小题13】答案：B他不得不独自承受这一切。15空后Steve was going through也有提示。go through经历，遭受；break through突破；look through浏览；push through使通过。
【小题14】答案：A我太以自我为中心了。19空前的we focus so such on ourselves也有提示。be focused on注意力集中于；be hooked on对……着迷；be dependent on取决于；be hard on严厉对待。
【小题15】答案：C我从未想过Steve经受着什么。what引导宾语从句，且在从句中作宾语，意思是“什么”。
【小题16】答案：D他不得不做出结束它生命的决定。根据文章第一句中had to be put down可知，狗是被药毒死的。put down毒死(衰老或有病的动物)；人道毁灭。
【小题17】答案：C根据第5空后a week after it happened可知选C项。
【小题18】答案：A不仅没能意识到Steve的良苦用心，还生他的气，我现在觉得后悔不已。regret后悔；blame指责；sorrow悲伤；sympathy同情。
【小题19】答案：B我们对自己关注得太多，以至于忽略了别人的痛苦。ignore忽视；share分享；remind提醒；rid摆脱。
【小题20】答案：C那一刻，妈妈的话是一份极好的礼物，让我永生难忘。gift礼物；comfort安慰；compromise妥协；suggestion建议。
