Q: Whose backpack is heavier? 二、本单元语法要点梳理 1. as ... as ... 表示同级比较 （1）as + 形容词原级 + as 表示两个人或事物在某一方面程度相同，常译为“和……一样……”。在描述山川河流时，可以说：The Yangtze River is as famous as the Yellow River. 长江和黄河一样有名。 （2）This mountain is as high as that one. 这座山和那座山一样高。 （3）as ... as ... 中的形容词要用原级，不可用比较级或最高级；可说 as high as，不可说 as higher as 或 as highest as。 2. not as/so ... as ... 表示不如…… （1）not as + 形容词原级 + as 或 not so + 形容词原级 + as 表示前者在某方面比不上后者，常译为“……不如……”或“……没有……那么……”。 （2）This lake is not as deep as that one. 这个湖不如那个湖深。 （3）否定比较时中间同样是形容词原级，不能误用比较级；不能说 This river is not as longer as that one。 3. 不定代词如 something, anything, nothing, someone 等作主语时谓语用单数 （1）something, anything, nothing, someone 等复合不定代词作主语时，谓语动词要用单数形式，因为它们在意义上被视为一个整体。 （2）Something is moving in the forest. 森林里有什么东西在动。 （3）something, someone 多用于肯定句；anything, anyone 多用于否定句或疑问句。例如：Is there anything interesting near the river? 河边有什么有趣的东西吗？ （4）不可说 Something are wrong. 应该说 Something is wrong. 注意谓语单数形式。 4. 形容词修饰复合不定代词时后置 （1）当形容词修饰 something, anything, nothing, someone 等复合不定代词时，形容词必须放在这些不定代词的后面。 （2）There is something special in this mountain area. 这片山区有些特别的东西。 （3）比较：a special thing（形容词在前）与 something special（形容词在后）。不能说 special something。 三、单项选择（共45题） 从每小题所给的四个选项中，选出一个最佳答案。 1. My younger sister is ____ tall as my mother now, but she is only twelve. A. as B. so C. than D. more 【答案】A 【知识点】as ... as ... 表示同级比较 【解析】正确答案是 A。as ... as ... 用于肯定句表示同级比较，句意为“我妹妹现在和我妈妈一样高”，故选 as。选项 B so 通常用于否定句（not so ... as），此处是肯定句，故排除；选项 C than 用于比较级，而句中 tall 为原级，不能用；选项 D more 构成比较级，也不合适。 2. This mountain is not as high ____ that one, so it is easier to climb. A. as B. than C. like D. of 【答案】A 【知识点】not as/so ... as ... 表示不如…… 【解析】正确答案是 A。not as ... as ... 是固定结构，表示“不如……”，空格处需要填第二个 as。选项 B than 用于比较级，但句中用的是原级比较，不能与 as 搭配；选项 C like 意为“像”，但此处需要 as 构成比较结构；选项 D of 没有此用法。 3. Someone ____ knocking at the door right now, but I cannot see who it is. A. is B. are C. am D. be 【答案】A 【知识点】不定代词如 something, anything, nothing, someone 等作主语时谓语用单数 【解析】正确答案是 A。someone 是不定代词，作主语时谓语动词用单数形式，故用 is。选项 B are 是复数形式，不能与 someone 搭配；选项 C am 只用于主语 I；选项 D be 是原形，不能直接作谓语。 4. I have ____ to tell you about our school trip next week. A. something interesting B. interesting something C. anything interesting D. interesting anything 【答案】A 【知识点】形容词修饰复合不定代词时后置 【解析】正确答案是 A。形容词修饰复合不定代词时需后置，且肯定句中用 something 表示“某事”，所以 something interesting 正确。选项 B interesting something 顺序错误；选项 C anything interesting 中 anything 通常用于否定句或疑问句，此处是肯定句；选项 D 顺序错误且不定代词使用不当。 5. My younger brother runs ____ fast as me, and he often wins the race. A. as B. so C. than D. more 【答案】A 【知识点】as ... as ... 表示同级比较 【解析】正确答案是 A。as ... as ... 用于肯定句表示同级比较，句意为“我弟弟跑得和我一样快”，故选 as。选项 B so 通常用于否定句（not so ... as），此处是肯定句，故排除；选项 C than 用于比较级，而句中 fast 为原级，不能用；选项 D more 构成比较级，也不合适。 6. We will leave for the mountains ____ the sun rises early tomorrow morning. A. as soon as B. not as soon as C. as much as D. as well as 【答案】A 【知识点】时间状语从句引导词 as soon as；对比 not as/so ... as ... 结构 【解析】as soon as 引导时间状语从句，表示“一……就”，符合句意。B“not as soon as”不是引导从句的连词；C“as much as”表示程度比较；D“as well as”表示“也”，均不符合。本题同时考查 not as/so ... as ... 表示不如……的辨析，避免误用比较结构。 7. Something lost ____ way in the forest, and the rangers are searching for it. A. his B. its C. their D. something 【答案】B 【知识点】形容词性物主代词 its 修饰名词；对比不定代词 something 作主语时谓语用单数 【解析】something 指物，形容词性物主代词应用 its 表示“它的”。A“his”和 C“their”用于人；D“something”不能修饰 way。本题同时考查不定代词 something 作主语时谓语用单数，此处 lost 为单数动词形式。 8. I didn't see ____ at the library this morning, so I left early. A. anything strange B. strange anything C. anything strangely D. strangely anything 【答案】A 【知识点】形容词修饰复合不定代词时后置 【解析】形容词修饰复合不定代词时需后置，strange 是形容词，放 anything 后，故 A 正确。B 顺序错误；C、D 使用副词，不能修饰 anything。 9. My brother is as tall as me, and he ____ basketball now. A. is playing B. plays C. is play D. as playing 【答案】A 【知识点】现在进行时；对比 as ... as ... 同级比较结构 【解析】now 提示现在进行时，结构为 be + doing，主语 he 用 is，故 A 正确。B 是一般现在时；C 缺少动词-ing；D 中 as 不能构成进行时。本题同时考查 as ... as ... 同级比较结构，空格处应填谓语动词。 10. The river is not as wide as that one, but it ____ flood this summer. A. will B. is C. was D. would 【答案】A 【知识点】will 表示将来；对比 not as/so ... as ... 结构 【解析】this summer 和句意表示对未来的预测，用 will + 动词原形 flood。B“is flood”语法错误；C“was”时态不对；D“would”通常用于过去将来或假设语气。本题同时考查 not as/so ... as ... 表示不如……的结构，空格处应填助动词构成将来时。 11. Something ____ wrong with my watch, so I cannot tell the exact time. A. are B. is C. am D. were 【答案】B 【知识点】不定代词如 something, anything, nothing, someone 等作主语时谓语用单数 【解析】正确答案是 B. is。不定代词 something 作主语时，谓语动词用单数形式；are 用于复数主语，am 只与 I 连用，were 是过去式复数，均不符合。 12. I have something ____ is very interesting to share with you all after class. A. important B. what C. that D. it 【答案】C 【知识点】正确答案考察定语从句关系代词 that 的用法；对比目标：形容词修饰复合不定代词时后置 【解析】正确答案是 C. that。something 是先行词，后面跟定语从句，关系代词 that 在从句中作主语；important 是形容词，放在 something 后作后置定语，但此处需要从句引导词，否则句子缺少主语；what 不能引导定语从句；it 不能连接两个句子。对比目标：形容词修饰复合不定代词时后置（如 something important），但此处需要定语从句结构。 13. My English is not as good as ____, so I need to practise more. A. her B. she C. hers D. herself 【答案】C 【知识点】正确答案考察名词性物主代词 hers 在 as ... as ... 比较结构中的用法；对比目标：as ... as ... 表示同级比较 【解析】正确答案是 C. hers。名词性物主代词 hers 相当于 her English，作比较对象；her 是形容词性物主代词，后面需跟名词；she 是主格，不能作宾语；herself 是反身代词，语义不通。对比目标：as ... as ... 表示同级比较，比较对象需用恰当代词形式。 14. This lesson is not as difficult ____ the last one, so I can finish it quickly. A. so B. as C. than D. like 【答案】B 【知识点】not as/so ... as ... 表示不如……，第二个 as 不能换成 so、than 或 like 【解析】正确答案是 B. as。not as/so ... as ... 结构中第二个 as 不可替换；so 只能用在第一个 as 的位置（not so ... as ...），than 用于比较级，like 是介词“像”，均不符合。本句意为“这节课不如上一节课难”。 15. Something fell on the floor, but ____ didn't break, so I picked it up. A. its B. it C. itself D. they 【答案】B 【知识点】正确答案考察人称代词 it 指代不定代词 something；对比目标：不定代词作主语时谓语用单数，代词指代一致 【解析】正确答案是 B. it。不定代词 something 指代前面出现的 something，用人称代词 it；its 是物主代词，不能作主语；itself 是反身代词，这里不需要强调“它自己”；they 是复数，与单数不定代词不一致。对比目标：不定代词如 something 作主语时谓语用单数，代词指代也需用单数形式。 16. I don't like ____ book because it is too difficult for me to read. A. this B. something interesting C. anything D. these 【答案】A 【知识点】指示代词 this 的用法（与形容词修饰复合不定代词时后置辨析） 【解析】句子中空格后是单数可数名词 book，需要单数指示限定词 this；these 是复数，不能修饰单数 book；something interesting 是复合不定代词加形容词后置，不能作限定词修饰名词；anything 是不定代词，同样不能修饰名词。因此选 A。 17. My school bag is ____ heavy as yours, so I can't carry it easily. A. as B. than C. so D. too 【答案】A 【知识点】as ... as ... 表示同级比较 【解析】同级比较的肯定句用 as...as...，所以选 as；than 用于比较级；so 通常用于否定结构 not so...as；too 表示“太”，不符合句意。因此选 A。 18. I have two books.

A. the other B. another C. other D. as 【答案】A 【知识点】不定代词 the other 的用法（与 not as/so ... as ... 结构辨析） 【解析】前文提到 two books，表示两者中的另一个用 the other；another 用于三者或以上，不符合；other 不能单独修饰单数名词；as 是连词，不作代词。因此选 A。句子中的 not as...as 是比较结构，空格处需要填表示两者中另一个的代词。 19. I have two pens, but ____ of them writes well, so I need a new one. A. neither B. none C. no D. something 【答案】A 【知识点】不定代词 neither 的用法（与复合不定代词作主语谓语单数辨析） 【解析】neither 表示两者都不，且谓语动词用单数 writes；none 用于三者或以上；no 是限定词，不能单独作代词；something 是复合不定代词，不能与 of them 连用。因此选 A。 20. There is ____ in the box. Can you guess what it is used for? A. interesting something B. something interesting C. anything interesting D. interesting anything 【答案】B 【知识点】形容词修饰复合不定代词时后置 【解析】形容词修饰复合不定代词时需后置，所以是 something interesting，排除 A 和 D；肯定句中用 something 而不用 anything，排除 C。因此选 B。 21.

A. is B. are C. be D. am 【答案】A 【知识点】不定代词 something 作主语时谓语动词用单数 【解析】不定代词 something 作主语时，谓语动词用单数形式，故选 is。are 用于复数主语，be 是原形，am 只与 I 连用。 24. ____ river is the longest in China, and is there anything special about it?

Someone from the science club ____ a robot demonstration for us next Friday. A. will give B. gives C. give D. gave 【答案】A 【知识点】不定代词作主语时谓语用单数；在表示将来时间时用 will + 动词原形。 【解析】主语 someone 是不定代词，谓语动词需用单数形式；句中的 next Friday 表示将来时间，因此用 will give。选项 B gives 是一般现在时，不能表示将来；选项 C give 未使用单数形式；选项 D gave 是过去式，与 next Friday 时间矛盾。 32.

A. him B. he C. his D. himself 【答案】A 【知识点】在 not as ... as ... 结构中，第二个 as 后的人称代词常用宾格形式。 【解析】not as ... as ... 表示“不如……”，第二个 as 后可视为介词，故用宾格 him。选项 B he 是主格，不能作介词宾语；选项 C his 是物主代词，不符合此处需要宾格的语法；选项 D himself 是反身代词，在此不必要。 35. Something made ____ home in the old tree near our school last year. A. its B. it's C. it D. their 【答案】A 【知识点】不定代词 something 作主语时谓语用单数；物主代词 its 表示“它的”。 【解析】主语 something 是不定代词，谓语动词 made 用单数形式；空格后需要物主代词修饰名词 home，用 its。选项 B it's 是 it is 的缩写，不能作定语；选项 C it 是宾格，不能作定语；选项 D their 是复数物主代词，与 something 单数不一致。 36.

A. are B. is C. am D. be 【答案】B 【知识点】不定代词如 something, anything, nothing, someone 等作主语时谓语用单数 【解析】复合不定代词 nothing 作主语时谓语动词用单数，故选B is。A项 are 为复数；C项 am 用于主语 I；D项 be 为动词原形，不能作谓语。 40. ____ of the two rivers is not as long as the Yangtze River. A. Neither B. None C. No D. Nothing 【答案】A 【知识点】不定代词 neither, none, no；对比形容词修饰复合不定代词时后置 【解析】neither 表示“两者都不”，与 of the two rivers 一致，故选A。None 通常用于三者或以上；No 不能直接与 of 搭配；Nothing 不可指代具体两者。本单元目标“形容词修饰复合不定代词时后置”为对比辨析点，本题实际考查不定代词 neither 的用法。 41. The two mountains are ____ beautiful, but neither is as high as Qomolangma. A. all B. both C. either D. neither 【答案】B 【知识点】不定代词 both, all, either 的区别（对比 as...as... 同级比较） 【解析】both 用于两者，all 用于三者或以上，either 表示两者中任意一个但此处语义不通，neither 表示两者都不，与句中已有的 neither 重复且逻辑相反。该句还包含 as...as... 同级比较结构，但空格处需要表示“两者都”的代词，故选 both。 42.

A. a few B. few C. little D. a little 【答案】B 【知识点】不定代词 few, a few, little, a little 的区别（对比复合不定代词作主语的单数谓语） 【解析】friends 是可数名词复数，little 和 a little 只修饰不可数名词，可排除；few 表示“几乎没有”，a few 表示“有一些”，由 lonely 可知朋友很少，故用 few。 44. ____ is your favourite subject at school this term then, maths or English? A. What B. Who C. Which D. Whose 【答案】C 【知识点】疑问代词 which 的用法（对比形容词修饰复合不定代词后置） 【解析】在 maths or English 这一明确范围中选择，用 which 提问；what 用于无范围选择，who 指人，whose 表所属。另外，形容词修饰复合不定代词时要后置，如 something interesting，本题考的是疑问代词，需区分两者。 45. The math problem is ____ difficult as the science one, so both take time. A. more B. most C. as D. than 【答案】C 【知识点】as ... as ... 表示同级比较 【解析】as...as... 表示同级比较，第一个 as 后接形容词原级；more 和 most 是比较级和最高级，than 与比较级连用，均不符合，故选 as。 四、语法选择（共10分） 请通读下面短文，掌握其大意，根据语法和上下文连贯的要求，从每小题所给的四个选项中选出一个最佳答案。 Last summer, I went to a mountain village with my parents. The village was near a clear river. The mountains were tall and green. We 1 in a small hotel for three days. Every morning, we walked 2 the river. The water was so clean that we could see fish swimming under the surface. While my mother 3 photos, my father and I watched the fish. We also saw some wild birds in the trees. One day, we decided to climb the highest mountain. My father told me 4 the mountain was over 1,000 metres high. "I 5 never seen such a beautiful view," he said when we reached the top.
