1选择题
阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Hi, I'm Amy. Before, I was short and thin. I had short hair and I didn't like sports. I couldn't ride a bike. But now I am tall and strong. I have long hair and I like playing badminton. I can ride a bike to the library. Last Sunday, I went to the library and read three books.
Which of the following sentences is TRUE about Amy?
- A. She had long hair before.
- B. She couldn't ride a bike before.
- C. She doesn't like sports now.
- D. She read books at home last Sunday.
答案：B
解析：这是一道细节理解题，需要在短文中逐项核对。A项：短文说 "I had short hair"，过去是短发，A项说过去长发，错误。B项：短文说 "I couldn't ride a bike"，与选项完全一致，正确。C项：短文说现在 "I like playing badminton"，C项说现在不喜欢运动，错误。D项：短文说 "Last Sunday, I went to the library"，是在图书馆读书，不是在家，错误。易错点：一是把 before 和 now 的信息张冠李戴，看到 long hair 就选 A，忽略了它是现在的特征；二是忽略 didn't、couldn't 这类否定词，把 "couldn't ride a bike" 误读成会骑车。故选B。
2选择题
阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Lily is twelve years old now. Five years ago, she was short and thin, and she couldn't ride a bike. She walked to school with her mother every day. She didn't like maths at that time. Now Lily is tall and strong. She goes to school by bike. She likes maths very much, and she often helps her little brother with his maths homework. Before, Lily's street was quiet and there were no shops. Now there are three small shops on the street, so it is easy to buy school things near her home.
Which of the following is TRUE about Lily?
- A. She could ride a bike five years ago.
- B. She didn't like maths before, but she likes it now.
- C. She goes to school on foot every day now.
- D. There were three shops on her street before.
答案：B
解析：细节理解题，重点是根据 before / now / five years ago 等时间状语判断时态与事实。A 项与原文 "couldn't ride a bike" 矛盾；C 项与原文 "goes to school by bike" 矛盾，步行是以前的事；D 项与原文 "Before, ... there were no shops" 矛盾，三家店是现在的情况。B 项与原文 "She didn't like maths at that time" 与 "She likes maths very much" 完全吻合。易错点：混淆 before 和 now 对应的状态，把今昔情况张冠李戴。故选B。
3选择题
阅读下面短文，从每题所给的A、B、C和D四个选项中，选出可以填入空白处的最佳选项。
My name is Lucy. Five years ago, I ______ small and short. I ______ ride a bike to school, and I ______ not like maths. Now I am tall. I ______ a good student in my class, and I often help my classmates with maths.
- A. am; can; do; am
- B. was; could; did; am
- C. was; can; did; was
- D. were; could; do; am
答案：B
解析：本题考查今昔对比中的时态运用。第一空所在句有时间状语 Five years ago，说明是过去的情况，主语 I 是单数，be 动词应用过去式 was，排除 A、D。第二空同样描述过去的能力，应用 can 的过去式 could。第三空是过去否定，借助助动词 did not (didn't)。第四空由 Now 可知是现在的状态，主语 I 配 am。常见错误：一是忽略 ago 这一时间标志，误用现在时；二是把 I 误配 were（were 用于复数主语或 you）。故选B。
4选择题
阅读下面短文，从每题所给的A、B、C和D四个选项中，选出最佳选项。
Ten years ago, my hometown was very small. There were no tall buildings, and there was only one small shop. People went to work by bike or on foot. But now, things are different. There are many new buildings and a big supermarket. Most people drive cars to work, and there is a new park for children to play in.
Which of the following sentences is TRUE about the hometown now?
- A. There is only one small shop in the hometown.
- B. People in the hometown go to work by bike or on foot.
- C. There are many new buildings and a big supermarket.
- D. There are no places for children to play.
答案：C
解析：本题考查今昔对比的细节理解。题干问的是现在的状况（now），需锁定短文后半部分。文中说 There are many new buildings and a big supermarket，与 C 项完全一致。A、B 两项都是十年前的情况（only one small shop、by bike or on foot），属于时态混用的干扰项；D 项与原文 there is a new park for children to play in 矛盾。易错点：读题时忽略 now，把过去的情况误当成答案。故选C。
5填空题
根据短文内容，用括号内所给词的适当形式填空。
Look at our town. Before, there (be) ________ only one small shop here. People (can not) ________ buy many things, so they (go) ________ to the city every weekend. Now there is a big supermarket. Last week, my mother (buy) ________ a new schoolbag for me there. We are happy now.
答案：1. was
2. couldn't
3. went
4. bought
解析：本题考查一般过去时在今昔对比语境中的运用。第1空：时间词 Before 提示说过去的事，主语 one small shop 是单数，be 动词用过去式 was，不能填 is 或 were（复数才用 were）。第2空：Before 提示过去，"can not" 的过去否定形式是 couldn't，注意不能写成 couldnot，也不能写 can't。第3空：与 Before 呼应，go 的过去式是 went，属于不规则变化，不能写 goed。第4空：Last week 是明确的过去时间标志，buy 的过去式是 bought，同样为不规则变化。易错点：一是忽视 Before、last week 等时间标志，误用现在时；二是 be 动词单复数混淆，单数误填 were；三是把不规则动词过去式规则化，写成 buyed、goed。
6解答题
根据句意，用括号中所给词的适当形式填空，使句子完整正确。
1. Ten years ago, there ________ (be) no supermarket in our town, but now there ________ (be) two big ones.
2. I ________ (be) short and quiet before. Now I ________ (be) tall and active.
3. Last Saturday, my mother ________ (buy) a new schoolbag for me at the mall.
4. Before, we ________ (not have) a computer at home, so I ________ (not use) the Internet.
5. Yesterday evening, Dad ________ (cook) noodles and I ________ (help) him in the kitchen.
答案：1. were; are
2. was; am
3. bought
4. did not have (didn't have); did not use (didn't use)
5. cooked; helped
解析：本题考查一般过去时与一般现在时的对比运用，重点是 be 动词的过去式 was/were 及规则/不规则动词过去式。第 1 题 There be 句型中，ten years ago 是过去时间，two... 是复数，故填 were；now 表示现在，two big ones 是复数，故填 are。易错点：受中文影响写成 was，或忽略主语的单复数。第 2 题 before 提示过去，主语 I 用 was；now 提示现在，主语 I 用 am，易错写成 is。第 3、5 题 last Saturday、yesterday evening 是过去时间状语，buy 的过去式是不规则变化 bought（易错写成 buyed），cook、help 是规则变化，直接加 -ed。第 4 题 before 提示过去，否定用 didn't + 动词原形，易错写成 didn't had 或 not had（缺少助动词 did）。总结：看到 before、last...、yesterday、... ago 用过去式；看到 now、every day 用一般现在时。
7解答题
根据答句，补全下列特殊疑问句，每空一词。
1. —________ ________ you ________ last Sunday?
—I visited my grandparents and cleaned their house.
2. —________ ________ you go last summer holiday?
—I went to Yunnan with my parents.
3. —________ was your school like ten years ago?
—There was only one small teaching building, but now there are three tall ones.
4. —________ did you go to the science museum yesterday?
—I went there by subway.
5. —________ did you do at the shopping centre last weekend?
—I bought some books and a pair of shoes.
答案：1. What did; do
2. Where did
3. What
4. How
5. What
解析：本题考查过去时特殊疑问句的构成：疑问词 + did + 主语 + 动词原形。第 1 题答句回答的是做的事情，用 What did you do...，易错写成 What did you visited...（did 后动词必须还原为 visit/do）。第 2 题答句回答地点（Yunnan），用 Where did you go...。第 3 题答句描述学校的样子，用 What was ... like（询问事物的特征/样子），易错用 How。第 4 题答句回答交通方式（by subway），用 How did you go...。第 5 题答句回答做的事情，用 What did you do...。总结易错点：一是助动词 did 后动词未还原；二是疑问词选择不当（地点用 Where、方式用 How、事情用 What）；三是语序混乱，写成 What you did do 之类。
8解答题
根据中文提示，用括号内所给词的适当形式完成句子，每空一词。
1. 五年前，我家附近没有书店。Five years ago, there ________ (not be) any bookshop near my home.
2. 现在我每天步行去上学。Now I ________ (walk) to school every day.
3. 上周日，我和妈妈去商场买了一条新裙子。Last Sunday, my mother and I ________ (buy) a new dress at the shopping centre.
4. 以前我奶奶不喜欢在网上购物。Before, my grandma ________ (not like) shopping online.
5. 昨天你买了多少本笔记本？How many notebooks ________ you ________ (buy) yesterday?
注意：每空必须写出完整的单词，注意时态与主谓一致。
答案：1. wasn't（there wasn't any bookshop...）
2. walk（Now 提示一般现在时，主语 I 用动词原形 walk）
3. bought（Last Sunday 提示一般过去时，buy 的过去式是 bought）
4. didn't like（Before 提示过去时，否定结构 didn't + 动词原形）
5. did; buy（yesterday 提示过去时一般疑问句：Did + 主语 + 动词原形，首字母大写写作 "How many notebooks did you buy yesterday?"）
解析：本题考查过去时与现在时的转换及否定、疑问结构。第1题易错写成 wasn't 写成 not be 的原形；there be 句型过去时单数用 there was，否定为 there wasn't。第2题 Now 是一般现在时标志，主语 I 后用 walk，不要写 walks。第3题易错写成 buyed，buy 是不规则动词，过去式为 bought。第4题易错写成 didn't liked，didn't 后动词必须还原为 like。第5题易错在 Did 后仍写 bought，正确形式是 did you buy。总结：说过去用过去式，说现在用现在时，didn't 和 Did 后一律接动词原形。
