1. We used to fly kites in the park. 我们从前常在公园里放风筝。
【详解】
1. used to do sth. 过去常常做某事
意思就是：以前经常干这件事，现在已经不做了。这个短语只用于描述过去，没有现在时态。
✅否定形式：didn’t use to do / used not to do（两种都对，前者日常更常用）
✅疑问形式：Did + 主语+ use to do...?
�例句：I used to walk to school. 我以前常常步行去上学。
2. be used to doing sth. 习惯于做某事
这里重点注意：末尾的to 是介词，不是不定式符号，所以后面必须加动词ing 形式。时态跟着主语变，现
在习惯、过去习惯都能用。
�例句：She is used to drinking milk every morning. 她习惯每天早上喝牛奶。
3. be used to do sth. = be used for doing sth. 被用来做某事
这是被动语态，专门用来讲物品的用途，翻译为“某物被用来做什么”。
�例句：Knives are used to cut things. 刀子是用来切东西的。
【典例】
He ______ live in the countryside, but now he lives in the city.
A. used to
B. is used to
C. was used to
答案：A
解析：句子里有明显的对比词but now（但是现在），说明前后是“过去”和“现在”的状态对比。
• A 选项used to + 动词原形，表“过去常常”，完全符合句意；
• B 选项is used to 后面必须接动词ing，而空后是动词原形live，搭配直接错误；
• C 选项was used to 是被动结构，表“被用来”，主语是人，语义完全不通。
【即练1】
She ______ getting up early every day.
A. used to
B. is used to
C. was used to
【即练2】
Wood ______ make paper.
A. used to
B. is used to
C. is used to do
【即练3】
I ______ swim, but now I can swim very well.
A. didn’t use to
B. used not
C. don’t use to
2 You know some people’s memory gets worse as they get older. 你知道有些人的记忆力会随着变老不断衰
退。
【详解】
1. get + 形容词比较级
get 在这里是系动词，意思是“变得”，后面加上形容词比较级，表达“慢慢地变得越来越……”，强调一个变
化的过程。get 的形式要跟着主语变：主语单数/不可数名词用gets，主语复数用原形get。
�例句：The flowers get more beautiful in spring. 花儿在春天变得越来越美。
2. as 连词
这个词有三个常用意思，本句里是“随着”，引导时间状语从句；另外还能表示“因为”（表原因）、“当……
的时候”（表时间），做题结合句意判断就行。
�例句：As time goes by, we grow up. 随着时间流逝，我们慢慢长大。
3. 名词所有格people’s
复数名词变所有格，一般直接在后面加’s，用来表示“……的”，本句people’s memory 就是“人们的记忆力”。
�例句：These are students’ books. 这些是学生们的书。
【典例】
The days ______ in summer.
A. get long
B. get longer
C. gets longer
答案：B
解析：
第一步看主语：the days（白天）是复数，所以动词要用原形get，排除C（gets 是三单形式，对应单数主语）；
第二步看句意：夏天的白天和其他季节对比，是“变得更长”，需要用形容词比较级longer，A 用的是原级
long，没有对比含义，排除。最终选B。
【即练1】
The weather ______ when autumn comes.
A. get cool
B. gets cooler
C. get cooler
【即练2】
______ he grew older, he became wiser.
A. Because
B. As
C. If
【即练3】
Our life is ______ than before.
A. getting better
B. get better
C. gets good
3 In your case, your grandma still remembers that you love cookies! 就你的情况来说，你奶奶依然记得你爱
吃饼干！
【详解】
1. in one’s case 固定短语
翻译为“就某人而言、针对某人的情况”。这里的one’s 必须用形容词性物主代词（my/your/his/her 等），不
能用人称代词或者名词性物主代词。
�例句：In her case, reading helps her relax. 就她而言，阅读能帮她放松。
2. remember + that 引导宾语从句
that 只是引导词，没有实际意思，口语和写作里还可以省略。
�例句：I remember (that) you like apples. 我记得你喜欢苹果。
3. 宾语从句时态规则：主现从任意
当主句的动词是一般现在时（本句remembers），从句的时态不用受主句限制，根据从句自己的时间、事实
来变：过去的事用过去时，现在的事用现在时，客观真理永远用一般现在时。
4. remember 的两个易混搭配
◦remember doing sth.：记得做过某事（事情已经做完了）
�例句：I remember closing the door. 我记得我关过门了。
◦remember to do sth.：记得要去做某事（事情还没做）
�例句：Remember to close the door. 记得要去关门。
【典例】
I remember that he ______ to Beijing last year.
A. go
B. went
C. goes
答案：B
解析：
主句动词remember 是一般现在时，遵循“主现从任意”。从句里有时间状语last year（去年），明确是过去
发生的动作，所以动词要用一般过去式went。A 原形、C 三单都不符合过去时态，排除。
【即练1】
She remembers that we ______ friends since 2020.
A. are
B. have been
C. were
【即练2】
In ______ case, practicing every day is helpful.
A. you
B. your
C. yours
【即练3】
I still remember ______ (meet) you once.
4. Could you tell me why it is easy to forget a word? 你能告诉我为什么很容易忘掉一个单词吗？
【详解】
1. Could you tell me...? 委婉请求句型
这里的could 只是为了语气更礼貌、客气，不代表过去时态。这个句式后面接宾语从句，有一个硬性规则：
从句必须用陈述语序（主语在前，谓语在后），不能用疑问语序。
�例句：Could you tell me where the library is? 你能告诉我图书馆在哪里吗？
2. It is + 形容词+ to do sth. 形式主语句型
it 是形式主语，只是用来占位，避免句子头重脚轻；真正的主语是后面的不定式to do（做某事）。这个句
型翻译：做某事是……的。
�例句：It is happy to play with friends. 和朋友玩耍很开心。
3. why 引导宾语从句
why 是疑问副词，在从句里用来表示原因，同样要遵守陈述语序。
【典例】
Could you tell me ______?
A. where is the bank
B. where the bank is
C. where was the bank
答案：B
解析：
Could you tell me 后面接宾语从句，必须用陈述语序（主语+谓语）。
• A 是疑问语序（谓语is 在主语the bank 前面），错误；
• B 陈述语序，时态也为一般现在时，符合要求；
• C 不仅语序错误，还用了过去式was，本句没有过去的时间提示，时态也错。
【即练1】
It is difficult ______ English well.
A. learn
B. to learn
C. learning
【即练2】
Could you tell me ______ tomorrow?
A. when will the train leave
B. when the train will leave
【即练3】
It is ______ for us ______ enough sleep.
A. important; have
B. important; to have
5. This was why she dropped the grapes. 这就是她掉落葡萄的原因。
【详解】
1. This/That is/was why + 句子
翻译：这就是……的原因。why 后面接的是事情带来的结果。
�例句：I got sick. That was why I stayed at home. 我生病了，这就是我待在家里的原因。
2. This/That is/was because + 句子
翻译：这是因为……。because 后面接的是造成某件事的缘由。
�例句：I stayed at home. That was because I got sick. 我待在家里，那是因为我生病了。
3. 时态统一：主句用现在时is，就描述现在的事；主句用过去时was，就描述过去发生的事，前后时态保
持一致即可。
【典例】
He got up late. That is ______ he missed the bus.
A. because
B. why
C.that
答案：B
解析：
梳理逻辑：“起床晚”是原因，“错过公交车”是最终结果。
句型规则：why 后面接结果，because 后面接原因。本空后面是结果，所以用why。
【即练1】
He missed the bus. That is ______ he got up late.
【即练2】
This was ______ I succeeded at last.
A. why
B. because
C.that
【即练3】
This is ______ people love peaceful life.
A. why
B. so
C.that
6. It is easier to remember a summary than every word in a passage. 相比记住整篇文章每个单词，记住摘要
会更容易。
【详解】
1. It’s + 形容词比较级+ to do A than (to do) B
意思：做A 这件事比做B 这件事更……。than 前后的结构要对称，前面是to do，后面原本也该是to do，
不过后面的to 可以省略。
�例句：It is faster to walk than to run. 走路比跑步更慢。
2. 形容词比较级变化
单音节词一般直接加er（easy →easier）；多音节词（长单词）前面加more。
3. than：只要句子里出现than，就代表两者在对比，必须使用形容词/副词的比较级。
【典例】
It is ______ to study hard than waste time.
A. good
B. better
C. best
答案：B
解析：
看到关键词than，确定要用比较级。
• good 是原级；better 是good 的比较级；best 是最高级。结合规则，选比较级better。
【即练1】
It’s harder ______ (finish) the work alone than with help.
【即练2】
It is ______ (easy) to forgive than to hate.
【即练3】
It is more important ______ keep healthy than ______ make money.
7 .The more you review what you learn, the more likely you will remember it. 复习学到的内容越多，记住它
的概率就越大。
【详解】
1. The + 比较级，the + 比较级
超级经典的句型，翻译为：越……，就越……。两个the 一个都不能少，前后都必须搭配形容词/副词的比
较级。
�例句：The more you eat, the fatter you will be. 你吃得越多，就会越胖。
2. likely 是形容词，意为“有可能的”，the more likely 就是“可能性越大”。
3. 本句中what 引导宾语从句，作动词review（复习）的宾语。
【典例】
______ you practice, ______ better you will be.
A. More; the
B. The more; the
C. More; more
答案：B
解析：
固定句型The + 比较级，the + 比较级，前后都必须加定冠词the。只有B 选项符合这个结构。
【即练1】
The ______ (hard) he works, the ______ (happy) he is.
【即练2】
The more you read, the ______ knowledge you will get.
A. much
B. more
【即练3】
______ earlier you sleep, ______ healthier you feel.
8. Listening to recorded information can be very effective. 听录音资料（辅助记忆）效果很不错。
【详解】
1. 动名词（doing）作主语
把动词变成ing 形式，放在句子开头当主语，一般用来表示经常性、习惯性的动作。重点规则：动名词作
主语，整体看成单数，后面的谓语动词要用单数形式。
补充：不定式to do 也能作主语，多表示一次性动作。
�例句：Running is good exercise. 跑步是很好的运动。
2. can be + 形容词
can 是情态动词，情态动词后面永远接动词原形，所以这里用be 原形，再接形容词构成系表结构。
【典例】
______ (read) books is helpful.
答案：Reading
解析：
空格在句首，作整个句子的主语。动词原形不能直接作主语，要变成动名词Reading，首字母大写。
【即练1】
______ English songs ______ good for listening.
A. Sing; is
B. Singing; is
【即练2】
______ (exercise) every day keeps you healthy.
【即练3】
Learning new skills ______ (make) us smarter.
9 Many more memory techniques can be found in books or online. 在书本和网上能找到更多记忆技巧。
【详解】
1. 情态动词的被动语态：can/may/must + be + 动词过去分词
翻译：能够/可以/必须被……。当句子主语是“物”，且这个物是“被人做某个动作”时，就要用被动语态。
�例句：This room can be cleaned today. 这个房间今天可以被打扫。
2. 主动语态vs 被动语态：
主动：find sth.（某人找到某物）
被动：sth. can be found（某物能被找到）
3. many more + 可数名词复数：表示“更多的、额外的”，用来修饰可数名词。
【详解】
Trees can ______ (plant) in spring.
答案：be planted
解析：
树是“被人们种植”的，主语和动词是被动关系。情态动词can 后面接被动结构be + 过去分词，plant 的过
去分词是planted，所以填be planted。
【即练1】
Work can ______ (finish) in two hours.
【即练2】
Cars must ______ (check) every year.
【即练3】
Problems can ______ if we try our best.
A. solve
B. be solved

10 When squirrels run out of food, they go straight to the place where they hid nuts. 当松鼠食物耗尽时，它
们会径直前往储存坚果的地方。
【详解】
1. run out of 和run out 区分（必考）
◦run out of + 宾语：人作主语，表示“某人用完了某物”，后面必须加东西（宾语）。
�例句：I ran out of water. 我把水喝完了。
◦run out：物作主语，表示“某物耗尽了”，后面不能加宾语，也没有被动形式。
�例句：My water ran out. 我的水喝完了。
2. where 引导定语从句
先行词是表示地点的名词（本句the place），从句里不缺主语、宾语，只缺地点状语时，就用where 引导。
�例句：This is the park where we played. 这就是我们玩耍过的公园。
3. go straight to... 径直去往……
straight 本身既是形容词也是副词，不需要再加ly，固定用法。
�例句：Go straight to the classroom. 径直走向教室。
【典例】
We have ______ oil. We need more.
A. run out of
B. run out
答案：A
解析：
主语是We（人），且空格后有宾语oil（油）。根据规则：人作主语、后面有宾语，用run out of，选A。run
out 只能物作主语，且后面不能接宾语。
【即练1】
My money ______ yesterday.
A. ran out
B. ran out of
C.running out
【即练2】
This is the room ______ I live.

11 Humans do not know for sure what goes through their minds during the journey. 人类无法确切知晓大雁
在旅途中心里在想什么。
【详解】
1. what 引导宾语从句
what 是连接代词，在从句里可以充当主语或者宾语，从句依旧要使用陈述语序。注意：that 和what 不能
连用。
�例句：I don’t know what you want. 我不知道你想要什么。
2. for sure 固定短语
副词短语，意思是“确切地、毫无疑问地”，放在句中或句末都可以。
�例句：I know for sure he will come. 我确定他会来。
3. during + 时间段：介词，翻译为“在……期间”。
�例句：I read books during the holiday. 我假期里看书。
【典例】
I don’t know ______ he wants.
A. what
B. that
C.what
答案：A
解析：
从句里动词wants 缺少宾语，用what 指代事物作宾语。that 和what 两个引导词不能叠加使用，B 结构
错误，选A。
【即练1】
No one knows ______ is waiting outside.
A. who
B. whose
C. which
【即练2】

A. what
B. how

12 If I do forget some words, I shouldn’t panic. Just remember the key words and continue! 如果我忘词了，
不必慌张，记住关键词继续往下讲就好。
【详解】
1. if 引导真实条件状语从句：主将从现
规则：if 引导的从句用一般现在时，主句可以用将来时、情态动词（can/should/shouldn’t 等）。
�例句：If it rains tomorrow, we will stay home. 如果明天下雨，我们就待在家里。
2. do/does/did + 动词原形
这是强调用法，翻译为“确实、真的”。do/does 用于现在时，did 用于过去时，不管用哪个，后面都必须加
动词原形。
�例句：I do like music. 我真的很喜欢音乐。
3. shouldn’t + 动词原形
shouldn’t 是情态动词should 的否定形式，后面永远接动词原形，意为“不应该……”。
【典例】
I do ______(love) summer.
答案：love
解析：
do 在这里用来加强语气，表“确实”。助动词do 后面必须搭配动词原形，所以填love。
【即练1】

四、阅读理解
阅读短文，从每题所给的A、B、C、D 四个选项中选出最佳答案。
The word “kai he” (“开盒”), first from online game groups, has become a hot word on Chinese internet. It
means the bad act of showing others’ personal information, like real names, home addresses or phone numbers, in
illegal ways. This often happens because of online fights or conflicts between fans. It has made many people worry
about privacy protection and online violence.
In 2023, a well-known case about a teenager spread quickly online. The teen was said to use foreign databases
to “kai he” on strangers. This made the public very angry. The case showed that more young people are taking part
in online bullying. Some kids are the ones doing the bad things, while others are the victims (受害者).
Law experts say “kai he” breaks China’s Personal Information Protection Law. People who organize or join
such acts may face criminal punishment. For serious cases, they could even stay in prison for up to seven years.
