When I wanted to know what to do, someone put an English book in front of me. “Let’s share,” the girl beside me said. “Hi, I’m Carrie.” I looked up. It was the girl I helped that morning.

France is famous for ________ (葡萄酒). 【答案】wine 【解析】 【详解】句意：法国因葡萄酒而闻名。wine意为“葡萄酒”，是不可数名词，因此填wine。 2. I read an ________ (优秀的，极好的) article about France. 【答案】excellent 【解析】 【详解】句意：我读了一篇关于法国的精彩文章。根据汉语提示，表示“优秀的，极好的”的单词是excellent，形容词，在句中作定语，修饰后面名词article。故填excellent。 3. Dalian is a beautiful city on the ________ (海岸；海滨). 【答案】coast 【解析】 【详解】句意：大连是一座美丽的海滨城市。coast“海岸；海滨”，名词。on the coast是固定搭配“在海岸边”。 4. There are many ________ (台阶) in the Eiffel Tower. 【答案】steps 【解析】 【详解】句意：埃菲尔铁塔里有很多台阶。step意为“台阶”，在句中作主语，前面有“many”修饰，应用复数形式，故填steps。 （B）用括号中所给单词的适当形式填空。 5. In the past, a huge tower ________ （lie）in the small village. 【答案】lay 【解析】 【详解】句意：过去，一座巨大的塔坐落于这个小村庄里。时间状语是in the past，表示过去的状态，应该用一般过去时。lie表示“位于”时，过去式是lay。 6. If you prefer ________ (take) a river cruise, you can visit the River Seine. 【答案】to take 【解析】 【详解】句意：如果你想要乘船沿河游览，你可以游览塞纳河。“prefer to do sth”表示“宁愿/更喜欢去做某事”。to take a river cruise整体作动词prefer的宾语（不定式充当宾语），故填to take。 7. Big cities always have ________ (rich) education resources than small ones. 【答案】richer 【解析】 【详解】句意：大城市总是比小一些的城市拥有更丰富的教育资源。根据“than”可知，需要用形容词比较级。rich的比较级需要+er，应填richer。 8. Shanghai is one of the most ________ (visit) cities in the world. 【答案】visited 【解析】 【详解】句意：上海是世界上游客最多的城市之一。visit“参观；访问”，为动词。句中“cities”为名词，前面需要用形容词修饰，且根据句意“游客最多的城市”可知，此处应表达“被参观的”，需用过去分词visited作形容词，表示“（被）访问的；游览胜地的”。 （C）在空白处填入适当的词。 9. The teacher has something ________ every student. 【答案】for 【解析】 【详解】句意： 老师有一些东西给每个学生。句中“has something”表示“有一些东西”，结合语境，这里表达的是老师有东西要分发给学生。表示“给某人某物”或“为某人准备某物”常用介词for来引出对象，构成 “have something for sb.”的固定搭配。应填入介词for，表示“给；为了”。 10. Tom had to write a report about Chinese history ________ he went to the library. 【答案】so 【解析】 【详解】句意：汤姆不得不写一篇关于中国历史的报告，所以他去了图书馆。句中前半句说明“汤姆需要写一篇关于中国历史的报告”，后半句说明“他去了图书馆”，两者之间存在因果关系——因为要写报告，所以去图书馆查资料。so“所以，因此”，是表示因果关系的连词，连接前因后果，符合语境。 二阅读理解（4*2=8分） A Wonderful Trip to France France is a beautiful country in Western Europe.
