三、单项选择。
1. This is my ________, and these are his ________.
A. dogs；dogs B. dog；dog C. dog；dogs D. dogs；dog
【答案】C
【解析】句意：这是我的狗，这些是他的狗。
考查名词。根据“This is”可知，第一空应用单数名词；根据“these are”可知，第二空用复数名词，故选C。
2. There ________ an apple and three ________ on the table.
A. are, glass of water B. is, glasses of water C. are, glasses of water D. is, glass of water
【答案】B
【解析】句意：桌子上有一个苹果和三杯水。
考查主谓一致和不可数名词的表达。there be句型中，be动词形式与最接近的名词一致，应与“an apple”一致，用is；water是不可数名词，表达数量应用量词，空前有“three”修饰，glass用复数形式，而water不能加s，应表达为three glasses of water，故选B。
3. — What’s on the table
—There is a lot of ________ on it. I like eating it very much.
A. books B. orange C. bread D. vegetables
【答案】C
【解析】句意：——桌子上有什么？——有很多面包，我非常喜欢吃。
考查名词辨析和不可数名词。books书；orange橙汁；bread面包；vegetables蔬菜。There is…“有”，主语应该是单数或不可数名词，排除A和D；根据“I like eating it very much”，B选项是饮料，不是吃的。故选C。

A. tomatos; chicken B. tomatoes; chickens C. tomatoes; chicken D. tomatos; chickens
【答案】C
【解析】句意：汤姆和蒂姆吃了一些西红柿和鸡肉。
考查可数名词复数和不可数名词。tomato表示“西红柿”，其复数形式为tomatoes；chicken表示“鸡肉”时，是不可数名词，表示“小鸡”时，是可数名词。根据“Tom and Tim have some...”可知此处是指鸡肉，故选C。
5. There is a ________ shop and two ________ shops not far away from my school.
A. sport; shoes B. sports; shoes C. sport; shoe D. sports; shoe
【答案】D
【解析】句意：离我的学校不远有一家体育用品店和两家鞋店。
考查名词的用法。sport运动，复数形式为sports；shoe鞋，复数形式为shoes。sports shop“体育用品商店”，固定短语；shoe shop“鞋店”，shoe是名词做定语，故用单数形式，变复数时，只需要shop变复数，shoe不变。故选D。
6. —Did you watch TV at home last Sunday
—No, I fed some ________ at my grandma’s home.
A. cow B. sheep C. chicken D. dog
【答案】 B
【解析】句意：——上星期天你在家看电视了吗？——没有，我在奶奶家喂了一些羊。
考查名词辨析。cow奶牛；sheep羊；chicken鸡；dog狗。空前面有some修饰，后面如果是接可数名词应该用其复数形式。只有B选项sheep单复数形式相同，cow、chicken和dog都是单数。故选B。

— Of course. But don’t eat too much.
A. bread B. noodle C. dumpling D. hamburger
【答案】A
【解析】句意：—— 妈妈，我饿了。我可以吃点面包吗？—— 当然。但是不要吃太多。
考查可数名词和不可数名词。bread面包；noodle面条；dumpling饺子；hamburger汉堡包。根据“some”可知，此空需要一个不可数名词或者可数名词复数，结合选项，BCD均是可数名词单数形式，因此“bread”符合句意。故选A。
8. There is (有) much ________ in the plate (盘子).
A. banana B. apple C. pears D. chicken
【答案】 D
【解析】句意：盘子里有许多鸡肉。
考查名词辨析。banana香蕉，可数名词单数；apple苹果，可数名词单数；pears梨，可数名词复数；chicken鸡肉，不可数名词，根据空前的“much”修饰不可数名词可知，应该用chicken，故选D。
9. Let me show you some ________of some________.
A. photos, tomatoes B. photoes, tomatos C. photos, tomatos D. photoes, tomatoes
【答案】A
【解析】句意：让我给你看一些西红柿的照片。

10. We have much _________ to do every day.
A. work B. job C. jobs D. works
【答案】 A
【解析】句意：我们没太有太多的工作要做。
考查名词辨析。job和work都有“工作”的意思，job是可数名词，复数是jobs；work是不可数名词。空格前面的much修饰不可数名词。故选A。

A. grade；class B. grade；classes C. grades；class D. grades；classes
【答案】B
【解析】句意：凯特和爱丽丝在同一年级，但他们在不同的班级。
考查名词单复数。grade年级；class班级。第一空前为same，故grade应用单数形式，C、D选项可排除；第二空前为different，故class应用复数形式。故选B。
12. There ________ some ________ on the desk.
A. is; key B. are; keys C. is; keys D. are; key
【答案】B
【解析】句意：桌子上有一些钥匙。
考查主谓一致和名词复数。There be中be动词取决于其后的名词；some修饰可数名词复数或不可数名词，key为可数名词，此处应用复数形式，排除A/D选项；名词是复数，be动词应用are，故选B。
13. How much ________ do you want
A. pens B. apples C. coffee D. pears
【答案】C
【解析】句意：你想要多少咖啡？
考查名词辨析。pens钢笔，可数名词的复数形式；apples苹果，可数名词的复数形式；coffee咖啡，不可数名词；pears梨，可数名词的复数形式。how much修饰不可数名词，四个选项中只有coffee是不可数名词，故选C。

A. shoes; dollar B. pair of shoes; yuan C. shoes; yuan D. pair of shoes; dollars
【答案】 C

考查名词单复数和价格的表达。根据问句中的are可知问句主语为复数，排除B项和D项；dollar为可数名词，有复数形式，yuan没有复数形式，此处应该说80 dollars，排除选项A。故选C。
15. Reading English stories ________ a lot of ________.
A. are; funs B. is; fun C. are; fun D. is; funs
【答案】B
【解析】句意：读英语故事很有趣。
考查主谓一致和名词。句子主语是动名词短语“Reading English stories”，谓语动词应用单数形式，排除A/C选项；fun“乐趣”，是不可数名词，不可以加s，排除D选项，故选B。
16. There ________ two books and a cup on the table.
A. have B. are C. is D. be
【答案】B
【解析】句意：桌子上有两本书和一个杯子。
考查there be句型。在there be句型中，be动词的形式在人称和数上与其后面的主语保持一致。如果有两个或两个以上的名词作主语时，be动词与最近的主语保持一致。two books为可数名词复数，故be动词用are。there be句型不能与实义动词have或has同时使用。故选B。
17. There ________ a pencil and some books on the desk.
A. be B. is C. are D. am
【答案】B
【解析】句意：桌子上有一支铅笔和一些书。
考查主谓一致。此句是There be句型，谓语动词用“就近原则”，be与最近的名词保持一致，此处应与“a pencil”一致，be动词应用is，故选B。

A（地球的探索）
Men began to make maps of the world hundreds of years ago. But there was always something wrong in early maps, because people didn’t know much about the world then. They even thought the Earth was flat（扁平的）.
Some people might think the Earth was like a ball, but they could not be sure. And most people at that time would laugh at them when they said the Earth was a ball. About 500 years ago, people learned about the truth. Captain Magellan sailed(航行) his ships west. But he came back home from the east. He sailed around the Earth. Captain Cook also sailed west and came home from the east.
Both of the captains drew maps on their trips. These maps helped other people a lot. And then people could make better maps because they learned more and more about the world.
Before space travel began, our maps already(已经) looked really good. Now people can take photos of the Earth from space. These photos show the Earth in a new way. People are making maps of the world better and better.

【答案】BCBD

1.细节理解题。从because people didn’t know much about the world then。可知答案选B。
2.推理判断题。从Captain Magellan sailed(航行) his ships west. But he came back home from the east. He sailed around the Earth.从西方出发，东方回来，说明地球是圆的。
3．细节理解题。从太空拍照对地球更加了解，所以绘制地图更精准。
4.主旨大意题。本文讲述地图发展史。从航海家绘制的简易地图到卫星拍摄的地图。可知地图随着人类的认知不断深入而更加精准。
