6. need考点
①need+动词原形

【tips】need作为情态动词使用时，通常用在否定句或疑问句中。
He needn’t pay for it. 他没必要付钱。
-Need you go now?
-Yes, I must.
-No, I needn’t / No, you don’t have to. (注意否定回答)
【tips1】need也可作实义动词，其后接动词不定式。
①need + to do需要去做某事
②否定用助动词：don’t/doesn’t/didn’t need to do (要根据时态进行变化)
③变为疑问句时助动词要提前，Do/Does/Did... need to do...?
We need to think it over. 我们需要仔细考虑一下。
Does he need to know it? 他需要知道这事吗？

【tips2】need作实义动词，其后也可以接名词。

③变为疑问句时助动词要提前，Do/Does/Did... need + sth(名词)...?
He needs a new car.他需要一辆新车。
【tips3】need 的被动用法与考点
主动形式表被动含义need doing = need to be done (某事)需要被做
The room needs cleaning. = The room needs to be cleaned. 房间需要打扫。
类似用法的词：want, require
need do & need to do怎么判断呢？
1. You need to take good care of your mother. 你要好好照料你妈妈。
(这里的need是实义动词，因为need后面接to take，是to do形式)
2. There is enough time. You needn’t hurry. 有的是时间，你不必着急。
(这里的need是情态动词，因为need+ not=needn’t，并且后面接动词原形，hurry)
3. Will we need to show our passports? 我们需要出示护照吗？
(这里的need是____________动词，因为need后面接____________, 是____________形式)
4. Need I type this letter again? 我需要重新录入将这封信吗？
(这里的need是____________动词，因为need____________，并且后面接动词____________，____________)
need do & need to do怎么选择呢？
①判断横线后的单词是动词还是名词。尤其要注意help、drink、sleep等名词。
⚠ 如果是“______ any help”形式，一定是名词，这个时候不能用needn’t形式。
如果是“______ to help”形式，一定是动词，但前面有to，这个时候不能用needn’t形式。
如果是“______ help”形式，大概率是动词，这个时候要开始判断选项了。
②确定横线后是动词原形，开始判断选项
A. needn't B. don't need C. needn't to D. not need to
A) need not to B) didn't need C) don’t need D) need to
巩固练习
1. You ______ hurry. There’s enough time.
A. needn’t B. don’t need C. needn’t to D. not need

A. water B. watering C. to water D. watered
3. -Need I finish the report today?
-Yes, you ______. The boss needs it tomorrow.
A. need B. must C. can D. may
5. had better考点
①had better + 动词原形 (表建议或警告，缩写为’d better，否定式为 had better not + 动词原形)。
②无论主语是谁，始终用 had better，不用 has/have better (无时态变化)。
You’d better finish your homework.你最好完成作业。
She’d better not be late.她最好别迟到。(注意not位置)
You’d better take an umbrella. It’s raining.你最好带伞，在下雨。(表建议)

作文解析
一、写作思路（贴合上海新教材 “人物介绍 + 观点表达” 要求）
1. 结构搭建：“问候引入→核心信息（出生 + 简介 + 性格）→个人看法→总结结尾”
上海新教材强调 “逻辑清晰、层次分明”，因此发言稿需按 “总 - 分 - 总” 展开：
· 开头：承接题目给出的问候语，用简洁句子点明介绍对象，自然切入主题（避免冗余）；
· 主体：分 3 层呈现核心信息 —— 先提 “贫困家庭出身”（突出背景反差，为 “成功不易” 铺垫）；再按 “成长（意志 + 天赋）→比赛（经验积累）→巴黎奥运夺冠（最新成就）” 的时间线梳理经历（符合 “叙事类文本” 时间逻辑）；最后补充 “开朗、勤奋、善良” 的性格（让人物形象更立体）；
· 结尾：结合 “成功来之不易” 的提示，表达个人钦佩，提炼 “努力、坚持” 的精神价值（升华主题，呼应班会 “榜样学习” 的场景）。
2. 情境适配：符合 “校级班会 + 全校老师出席” 的正式场合
· 语言风格：用 “honoured”“inspire”“admire” 等正式词汇，避免口语化表达（如不用 “super good”，改用 “extraordinary”）；
· 情感基调：突出 “钦佩”，通过 “not easy”“kept practicing” 等细节体现对全红婵 “努力” 的认可，传递积极价值观（贴合教材 “正能量人物” 主题）。
二、好词好句（适配上海新教材词汇与句型，标注教材高频考点）
1. 人物背景与经历类（教材 “Past Experiences” 主题相关）
· 描述出身：“was born in a poor family in Zhanjiang”（简单句，符合基础表达；“born in” 为教材 8 年级核心短语）；
· 体现天赋与意志：“showed a strong mind and great athletic talent from an early age”（“from an early age” 是教材 “描述成长” 高频短语；“talent” 为 7 年级重点词汇，替换 “ability” 更精准）；
· 积累经验：“took part in many diving competitions and gained much experience as she grew older”（“take part in”“gain experience” 均为教材 8 年级 “活动参与” 主题核心搭配；“as she grew older” 引导时间状语从句，符合教材复合句要求）；
· 成就表述：“won the gold medal in the women's 10-metre platform diving at the Paris Olympics on August 6th, 2024”（日期表达 “on August 6th, 2024” 为教材 7 年级语法点；“win the gold medal” 是 “体育赛事” 主题固定搭配）。
2. 性格与品质类（教材 “Personalities” 主题相关）
· “She is outgoing, hard-working and kind-hearted.”（“outgoing”“hard-working” 为教材 7 年级 “描述性格” 基础词汇；“kind-hearted” 是合成形容词，丰富词汇形式，符合上海教材 “词汇多样性” 要求）；
· 体现勤奋：“kept practicing even when she faced difficulties”（“keep doing” 为教材 8 年级 “持续动作” 核心语法；“face difficulties” 是 “克服挑战” 主题常用表达）。
3. 个人观点与升华类（教材 “Opinions” 主题相关）
· 表达钦佩：“I admire her very much not only for her achievements but also for her spirit of never giving up.”（“not only...but also...” 为教材 8 年级并列连词重点；“never giving up” 是教材 “正能量品质” 高频短语）；
· 总结启示：“Her story tells us that success never comes easily and hard work always pays off.”（“tells us that...” 引导宾语从句，符合教材 9 年级语法要求；“pays off” 为 “努力有回报” 固定搭配，替换 “is useful” 更生动）。
参考答案1：
Good morning, everyone.
I'm very honoured to stand here and give you a short speech about Quan Hongchan. QuanHongchan was born in a poor family in Zhanjiang. Quan showed a strong will and sportsmanship from an early age. As she grew older, she took part in many competitions and gained a lot of experience. OnAugust 6,2024,17-year-old Quan Hongchan won the gold medal for the women's 10-metre platform
diving again. Hard work paid off. Quan Hongchan is a kind and diligent girl. She works very hard and goes all out in every training. Through her efforts, she succeeded.
That's all. Thanks for listening!
这篇发言稿紧扣 “校级班会介绍跳水冠军” 的情境，内容完整、逻辑清晰，既精准覆盖题目要求的 “出生、简介、性格” 等核心信息，又传递出对全红婵的钦佩之情，整体符合上海新教材对 “人物介绍类文本” 的写作要求，具体亮点与可优化之处分析如下：
一、核心亮点：贴合要求，扎实规范
1. 内容完整，信息无遗漏
严格遵循题目给出的表格要点：
· 背景层面：明确提及 “born in a poor family in Zhanjiang”，交代出身背景，为 “成功来之不易” 铺垫；
· 经历层面：按 “从小显天赋（strong will and sportsmanship）→ 成长中积累经验（gained a lot of experience）→ 巴黎奥运夺冠（won the gold medal... again on August 6, 2024）” 的时间线展开，叙事逻辑连贯，且精准使用题目提示的核心短语（10-metre platform diving, a lot of experience）；
· 性格与观点层面：点出 “kind and diligent” 的性格，并用 “works very hard and goes all out in every training” 具体诠释 “勤奋”，最后以 “Hard work paid off”“Through her efforts, she succeeded” 总结成功原因，呼应 “成功来之不易” 的提示，升华主题。
2. 语言简洁，符合发言稿语境
· 句式以简单句和并列句为主（如 “Quan showed... from an early age. As she grew older, she took part in...”），表达清晰易懂，适配 “班会发言” 的口头表达场景，听众易理解；
· 用词准确且贴合主题：“diligent”（勤奋的）替换基础词 “hard-working”，“goes all out”（全力以赴）生动体现训练态度，“Hard work paid off”（努力有回报）是高频正能量短语，简洁传递核心价值观，符合上海教材对 “词汇恰当性” 的要求。
3. 结构清晰，符合 “发言稿” 格式
开篇以 “Good morning, everyone” 问候，中间分 “人物经历→性格品质→成功启示” 三层展开，结尾用 “That's all. Thanks for listening!” 收束，结构完整，符合发言稿 “引入 - 主体 - 结尾” 的经典框架，体现对 “场合适配性” 的把握。
二、可优化方向：细节升级，更显生动
1. 姓名书写与标点：规范细节，避免小失误
· 姓名 “QuanHongchan” 应规范书写为 “Quan Hongchan”（姓与名之间空格），符合英文中 “中文姓名拼写规则”；
· 日期 “OnAugust 6,2024” 需调整为 “On August 6, 2024”（月份与日期、日期与年份之间空格），标点符号使用更严谨，这是上海教材中 “英文书写规范” 的基础考点。
2. 词汇与句式：增加多样性，提升表达质感
· 避免重复用词：文中 “experience”“hard”“succeeded” 等词出现频率较高，可适当替换，如 “gained a lot of experience” 改为 “gained rich experience”（“rich” 比 “a lot of” 更精准，体现经验 “丰富”），“works very hard” 改为 “devotes herself to every training”（“devote oneself to” 更能体现 “全身心投入”，比 “works hard” 情感更强烈）；
· 增加复合句，丰富句式：如将 “Quan Hongchan is a kind and diligent girl. She works very hard...” 合并为 “Quan Hongchan is not only kind but also diligent—she devotes herself to every training and never gives up.”（用 “not only...but also...” 并列连词和破折号补充细节，符合上海教材对 “句式多样性” 的提升要求，让表达更流畅）。
3. 情感表达：增加具体细节，强化 “钦佩” 之情
可补充 1-2 个体现 “成功不易” 的细节，让钦佩更有依据，如 “Even when she felt tired during training, she never stopped practicing—this is why I admire her most.”（通过 “训练疲惫仍不放弃” 的细节，让 “勤奋” 更具象，也让 “个人看法” 更真实，贴合班会 “榜样激励” 的目的）。
三、总结
整体而言，这是一篇 “合格且贴合要求” 的发言稿，核心优势在于 “紧扣题目、逻辑清晰、语境适配”，完全满足 “介绍全红婵” 的任务需求，体现了对基础词汇、句式和文体格式的扎实掌握。若优化上述细节，在 “书写规范”“表达多样性” 和 “情感具象化” 上稍作提升，将更符合上海新教材对 “优秀文本” 的要求，成为更亮眼的班会发言材料。
参考答案2：
Good morning, everyone.
I'm very honoured to stand here and give you a short speech about Quan Hongchan. She was born in a poor family in Zhanjiang. From an early age, she showed a strong mind and great athletic talent. As she grew older, she took part in many diving competitions and gained much experience. On August 6th, 2024, the 17-year-old Quan won the gold medal in the women's 10-metre platform diving at the Paris Olympics again.
Quan is outgoing, hard-working and kind-hearted. She kept practicing even when she faced difficulties. I admire her a lot—her success isn't easy, and her spirit inspires me to work harder.
That's all. Thanks for listening!
这篇发言稿紧扣 “校级班会介绍跳水冠军” 的核心情境，在内容完整性、逻辑连贯性和语言适配性上均表现出色，既精准覆盖题目要求，又贴合上海新教材对 “人物介绍类文本” 的写作标准，是一篇结构清晰、情感真挚的佳作，具体亮点与可借鉴之处分析如下：
一、核心亮点：精准扣题，逻辑与表达双优
1. 内容完整，要点无遗漏，贴合题目要求
严格遵循题目给出的 “出生、简介、性格、个人看法” 四大核心模块，且细节精准：
· 背景铺垫：开篇用 “She was born in a poor family in Zhanjiang” 交代出身，为后文 “成功不易” 埋下伏笔，符合 “人物介绍从基础信息切入” 的逻辑；
· 经历梳理：按 “幼年显天赋（strong mind and great athletic talent）→ 成长积经验（gained much experience）→ 奥运夺金（won the gold medal... again）” 的时间线展开，清晰呈现全红婵的成长轨迹，且精准使用题目提示的关键短语（10-metre platform diving, Paris Olympics），无信息偏差；
· 性格与观点：用 “outgoing, hard-working and kind-hearted” 概括性格，再以 “She kept practicing even when she faced difficulties” 具体诠释 “勤奋”，最后通过 “her success isn't easy, and her spirit inspires me to work harder” 表达钦佩与启示，呼应 “成功来之不易” 的提示，实现 “人物介绍→情感共鸣→价值传递” 的递进，符合班会 “榜样激励” 的场景需求。
2. 逻辑清晰，结构严谨，符合发言稿文体特征
完全遵循 “发言稿” 的经典结构：
· 开篇引入：承接题目给出的问候语，用 “I'm very honoured to stand here and give you a short speech about...” 自然切入主题，简洁不冗余；
· 主体分层：将 “成长经历” 与 “性格品质 + 个人看法” 分为两段，段落功能明确（第一段叙事，第二段抒情与议论），避免信息混杂，听众易跟随思路；
· 结尾收束：用 “That's all. Thanks for listening!” 规范收尾，符合口头表达的 “完整性” 要求，体现对文体格式的准确把握。
3. 语言规范，简洁生动，适配上海新教材要求
· 词汇选择：兼顾 “准确性” 与 “丰富性”—— 基础词汇（born, practice, difficult）保证理解度，进阶词汇（athletic talent, inspire）体现词汇储备，且 “hard-working”“kind-hearted” 等合成形容词、“gained much experience” 等固定搭配，均为上海教材 7-8 年级核心考点，贴合学生学习水平；
· 句式运用：以简单句和基础复合句为主（如 “As she grew older...” 引导的时间状语从句、“even when...” 引导的让步状语从句），句式不复杂但有变化，既符合 “口头发言易懂” 的需求，又体现对教材语法知识的灵活运用；
· 情感表达：通过破折号（“I admire her a lot—her success isn't easy...”）自然衔接观点与原因，语气真诚不生硬，让 “钦佩之情” 更易引发听众共鸣。
二、可微优化方向：细节升级，更显精致
1. 姓名拼写一致性：强化书写规范
文中首次提及 “Quan Hongchan” 时用全名，后文简写为 “Quan”，虽不影响理解，但在正式发言稿中，可统一为 “Quan Hongchan”（首次出现后，后文可用 “she” 指代），避免简称可能带来的 “不够正式” 感，更贴合 “全校老师出席” 的场合；若需简写，建议首次出现时标注 “Quan Hongchan (hereafter referred to as 'Quan')”，但对学生写作而言，直接用 “she” 指代更简洁，无需过度复杂。
2. 细节补充：让 “成功不易” 更具象
可增加 1 处微小细节，让 “勤奋” 与 “成功不易” 更具体，如在 “She kept practicing even when she faced difficulties” 后补充 “—she often spent extra time training after her teammates left”（“她常在队友离开后额外加练”），通过具象场景强化 “hard-working”，让 “钦佩” 的理由更充分，也让文本更有画面感，但当前版本已完整传递核心信息，此优化为 “锦上添花”，非必需。
三、总结
这篇发言稿是 “贴合任务、符合学情、适配场景” 的优秀范文 —— 既精准完成 “介绍全红婵” 的写作任务，又体现上海新教材对 “词汇、句式、文体” 的要求，更通过清晰的逻辑和真挚的情感，实现 “班会榜样介绍” 的目的。对学生而言，其写作思路（按 “时间线叙事 + 分层表达观点”）和语言运用（基础词汇与教材考点结合）具有极强的可借鉴性，是一篇值得参考的实用文本。

⚠ 如果是“______ any help”形式，一定是名词，这个时候不能用needn’t形式。
如果是“______ to help”形式，一定是动词，但前面有to，这个时候不能用needn’t形式。
