1．—Jack can't concentrate on his lessons recently.

2．The realization of the Chinese dream won't affect dreams of other countries.__On__ the contrary, it helps them realize their own dreams.

解析：本题考查名词性从句的引导词。句意：马铃薯是在什么时候被引进到欧洲的不确定，但是可能是在1565年左右。分析结构可知，此处是主语从句的引导词。根据but并列句中的关键词 around 1565可以知道，此处表示“时间”，故要用when引导主语从句。
5．The professor thought that the idea the young engineer brought __up__ was worth considering.
解析：句意：教授认为那位年轻的工程师提出的想法值得考虑。分析句子结构可知，“the young engineer ________”是定语从句，修饰先行词the idea，且根据句意可知，bring up“提出”符合句意。

7．“Every time you eat a sweet, drink green tea.” This is __what__ my mother used to tell me. 解析：本题考查名词性从句的引导词。句意：“每次你吃甜东西，喝点绿茶。”这是过去妈妈经常对我说的话。分析结构可知，此处考查的是表语从句的引导词。从句缺少tell的一个宾语，用what引导。
8．There is much chance __that__ Bill will recover from his injury in time for the race. 解析：There is much chance that...为常用句型，意为“很有可能……”。that引导的从句说明chance的内容，等同于同位语从句。
9．I found Jane __seated__(seat) at the desk, __doing__(do) her homework carefully. 解析：句意：我发现简坐在桌旁认真地做作业。seat为及物动词，用法为be seated或seat oneself，所以Jane后可接seated或sitting作宾补；doing her homework carefully是现在分词短语作伴随状语。
10．—Could I use this dictionary? —Just go__ahead__.It's a spare one. 解析：本题考查情景交际。句意：“我能用一下这本词典吗？”“________，这是多余的一本。”根据“It's a spare one.”可知，后者应该是同意前者使用这本词典。just go ahead意为“用吧”，表示同意，符合语境。
11．There is no greater pleasure than lying on my back in the middle of the grassland，__staring__(stare) at the night sky. 解析：本题考查非谓语动词。句意：没有什么能比躺在草地中央凝视着夜空让人感到更高兴的事儿了。根据句中的on my back可知，lying的动作由“我”发出，而stare的逻辑主语也是“我”，“凝视夜空”的动作由“我”主动发出，故用现在分词短语作状语，表示伴随。
12．Even the best writers sometimes find themselves __lost__(lose) for words. 解析：考查非谓语动词。句意：即使最好的作家有时发现自己无以言辞。be lost for words“说不出话来”。然后结合“find＋宾语＋宾语补足语”结构可知，此处用lost作宾语补足语。
