参考答案
1．D
【解析】句意：虽然阳光明媚，但并不很暖和。
考查连词辨析。If如果；Since自从，由于；Because因为；Though虽然，尽管。根据“the sun was shining, it wasn’t very warm”可知，前后句意是转折关系，前句表示让步条件，应用though引导让步状语从句，故选D。
2．D
【解析】句意：我永远不会忘记这个小镇和那里的人们，他们在我心中留下了许多柔软而甜蜜的回忆。
考查定语从句。此定语从句的先行词“the small town and the people there”既有人也有物，应用“that”引导此定语从句，故选D。
3．D
【解析】句意：他们是我的祖父母。他们结婚60年了。
考查延续性动词。根据句中时间状语“for sixty years”可知，此题应用现在完成时态，和时间段连用句中的谓语动词要用延续性动词，“结婚”的延续性动词是be married ，故选D。

【解析】句意：在春天，奶奶在花园里种了很多种类的蔬菜。
考查介词辨析。in用在年、月、上下午及季节的前面；at用于具体的时刻前面；on用于具体的某一天或具体某一天的上午、下午或晚上；since自从……。spring“春天”表示季节，因此其前应用介词in。故选A。

【解析】句意：夏天我的家乡经常下大雨。
考查形容词和副词辨析。heavy沉重的，是形容词； hardly几乎不，是副词；strongly强烈地，是副词；heavily沉重地，猛烈地，是副词。句中修饰动词rains，用副词，表示雨下得大，用副词heavily，故选D。
6．D
【解析】句意：我太重了。我不知道如何处理这个问题。
考查动词短语。care about关心；do with处理，与what连用；decide on 决定某事；deal with处理，与how连用。根据“ I don’t how to...the problem”可知，此处指我不知道如何处理这个问题，“how to deal with”“如何处理”。故选D。

8．B
【解析】句意：这是我去过的最美丽的城市。
考查定语从句。此处是定语从句，先行词是“city”，引导词在从句中作宾语，可用that/which引导，又因为先行词前有最高级修饰，所以只能用that。故选B。
9．C
【解析】句意：有一个男孩和两个女人在外面等你。
考查固定句型。“There be+名词/名词词组+doing something.”意为“有……正在做某事”，固定句型，现在分词“doing”所表示的动作和前面的人或物存在主谓关系，“doing”是现在分词作后置定语。There be句型中be动词形式是就近原则，由“a boy”是第三人称单数，可知be动词用is。故选C。
