参考答案及试题解析
1.A
【解析】句意:林楠总是忘记把铅笔带到学校。 forget忘记,实义动词;bring带来,实义动词。forget to do sth.忘记去做某事,指的是事情没有做;forget doing sth.忘记做了某事,事情做了。主语Lin Nan是单数,所以forget用单三式forgets,排除C、D;根据句子可知讲的是林楠总是忘记带铅笔,指的是事情还没有做,所以用to bring,故选A。
【点评】考查短语辨析,首先识记forget to do sth./doing sth.,然后根据主语确定谓语形式,理解句意。
2.B
【解析】句意:这是一次难忘的旅行。我永远不会忘记它。A健忘的,形容词,B难忘的,形容词,C忘记,副词,D过去分词,此处名词trip前面缺少形容词作定语,根据never forget it可知此次旅行很难忘。故选B。
【点评】考查形容词,学会分析句子结构,从而来判断所缺部分在句子中的成分。
3.A
4.B
【解析】句意:——对不起,我把练习本忘在家里了。——明天不要忘了带来。forget忘记,leave落下,leave+sth+地点是固定结构,把……忘在……,第一句是把练习本忘在家里了,用动词leave,过去式是left。take拿走,bring带来,第二句是明天不要忘记带来,用bring,故选B。
【点评】考查动词辨析。注意识记forget和leave,take和bring的区别。
5.C
【解析】句意:——你告诉杰克这个好消息了吗?——哦,我这些天如此的忙以至于我忘了。A动词原形,B动词的现在分词或者动名词,C动词的过去式,D动词的第三人称单数。由was可知时态是一般现在时态,动词用过去式,故选C。
【点评】考查动词的形式。注意根据语境确定时态,从而确定动词的形式。
6.D
7.A
【解析】句意:很多人喜欢在社交媒体上分享自己的日常生活。share 分享;hide 隐藏;forget 忘记;lose 丢失、失去。结合语句 "Many people like to… their daily lives on social media." 可知,社交媒体的核心功能之一是 "分享信息","share sth. on social media"(在社交媒体上分享某物)是符合日常场景的表达,"分享日常生活" 也符合人们使用社交媒体的常见行为。故答案为 A。
【点评】考查动词的辨析及语境匹配。解题关键在于结合社交媒体的核心用途(如信息分享、互动),以及 "人们对待日常生活" 的常见行为,判断 "share"(分享)是唯一符合语境和逻辑的选项。
8.C
【解析】句意:你离开时别忘了关掉风扇。A.turn(关闭,动词原形);B.turning(关闭,动名词/现在分词);C.to turn(关闭,不定式);D.to turning(错误形式)。根据语境可知,此处指"离开时忘记关风扇(未做)","forget to do sth"(忘记要做某事,未做),固定短语。故选C。
【点评】考查动词不定式。区分"forget to do sth"(未做)和"forget doing sth"(已做)的用法。
9.D

【点评】考查单词发音。注意音标/t //p k p/的正确发音。
14.B
【解析】句意:恐怕我们不能支付得起坐出租车。我们改乘地铁去吧。A.拒绝;B.负担得起;C.伪造;D.跌倒。根据"Let s go by underground instead(我们改乘地铁去吧)"可推测,此处指"支付不起",故选B。

15.B
【解析】句意:杰森,你出去的时候别忘了叫醒我。这是祈使句,否定祈使句是don't+动词原形开头的形式,故选B。

16.B
【解析】句意:别忘了明天把作业带到学校来。remember记得;forget忘记;leave离开,留下;lost丢失,迷路,失去的。动词leave与动词lost之后不能接动词不定式作宾语,故排除选项C和选项D,根据" Don't ____ to bring your homework tomorrow."可知,此处表示提醒对方不要忘记将作业带到学校,且"将作业带到学校"这一动作还未发生。故选B。
【点评】考查动词辨析。注意:分析句子结构,理解句子的整体结构,明确主语、谓语、宾语等关键成分,有助于判断所需动词的类型和形式。仔细阅读题干,捕捉关键词汇和短语,理解句子的语境和含义。有时,上下文中的时间、地点、人物等细节信息会提供解题的线索。

【点评】考查定语从句关系词的选择。关键在于判断先行词是人还是物,以及关系词在从句中充当的成分。当先行词为物,且在从句中作宾语时,可用关系代词 which。

【点评】考查不定代词。注意理解句意,识记在表示咨询或建议的疑问句中,用表示肯定意义的不定代词。
