当堂达标参考答案与解析:
Ⅰ. 1. mind keep sb. /sth. + adj.意为“使某人或某物保持某种状态”。句意:人们保持身心健康很重要。
2. percent ninety percent意为“百分之九十”。
3. died die“死亡,去世”。句意:埃里克的奶奶三天前去世了。根据句中的时间状语three days ago可知,本句是一般过去时态,die的过去式为died。
4. together together“在一起,共同”。空格所在句意为“我们在一起非常快乐”。
5. surprised be surprised to do sth.“对做某事感到吃惊”。
6. online shop online意为“网购,网上购物”。
Ⅱ. 1. through exercise 2. Seventy percent 3. such as 4. go online 5. don’t, at all
Ⅲ. 1. A although“虽然,尽管”;so“所以”;and“和,并且”;because“因为”。根据前后句句意“Mona经常吃垃圾食品”“她知道这对她的健康不好”可知,应用although引导让步状语从句,故选A。
2. C across“越过,横穿”,强调穿过平面;over“越过”,强调越过一段距离;through“穿过”,强调穿过空间;on“在……上”。由句意“月光透过窗子照进了房间”可知,月光穿过的是窗子的空间,through符合句意,故选C。
3. A such as与for example都可以表示“例如”,但such as后面不能用逗号隔开,且其后一般加短语,for example后面用逗号隔开,其后一般接句子;C项和D项不用于举例,故选A。
4. D 分析句子结构可知,taking exercise在句中作主语,谓语动词应用单数形式,可排除A、B两项。a good way to do sth.表示“做某事的好方式”,动词不定式作定语,故选D。
5. C 当“基数词+percent of+名词”作主语时,谓语动词的单复数形式要与of后面的名词的数保持一致,句中的students为可数名词复数,故选C。
