4a
Think about this question:"Is it still necessary to memorize things when they can be found online？"What is your opinion？
I think that it is still very necessary to memorize things.
I think we do not need to spend a lot of time memorizing things by rote.
4b
Form two groups based on different opinions.Add at least three reasons to support your opinion.
Opinion We need to memorize things. We don't need to memorize things.
Reason Memorizing things trains our brain. Everything we need is already online.
If we memorize things,we can use them right away. Memorizing things takes up too much time.
Sometimes online information is lost.What will we do then Thinking skills are much more improtant than memory.

记忆训练可以锻炼我们的大脑
记住内容后我们可以立刻使用，不受网络条件限制
线上的信息有时会丢失，记住内容能应对这种突发情况
我们需要的所有内容都已经能在网上找到
记忆内容会占用我们太多时间
思维技能远比死记硬背的记忆能力更重要
观点
我们需要记事
我们不需要记事
原因
train v.训练
train as ：接受训练成为某类职业/角色
train for ：为特定目标、赛事做训练
train sb. to do sth. ：训练某人掌握某项技能
train up ：充分培养、训练出完整能力
Key point
right away 马上；立刻
短语 风格特点 语义差异
right away 非常口语化，日常交流高频 强调“当下立刻做”，几乎没有延迟
immediately 偏正式，多用于书面语/正式通知 语义和right away一致，但语气更严肃
soon 通用口语/书面语 只表示“不久之后”，没有“立刻执行”的强即时感，可能是几小时甚至几天后
Key point
right away 马上；立刻
right away是固定短语，中间不能加任何词，不能写成right the away或者right a way；同义短语at once可以直接和它在句子里互相替换，句意完全不变。
Key point
take up
1.开始从事（爱好、技能、职业） ：指开启一项此前没有接触过的新活动，是最常考的义项之一。
2.占用（时间、空间、注意力） ：描述事物消耗了多少资源，也是完形填空里的高频考点。
3.接受（挑战、提议） ：回应他人给出的邀请或任务，属于次高频考点。
4.继续中断的事 ：从之前暂停的节点重新推进，阅读理解中偶尔出现。
Key point
take up
*高频固定搭配
take up a hobby 培养一个爱好
take up too much time 占用太多时间
take up the challenge 接受挑战
take up where you left off 从停下的地方继续
Key point

Use examples and data to support your opinions.
We need to memorize things
For the reason "Memorizing things trains our brain":
A 2024 survey of 200 middle school students in our city found that students who stick to reciting 10 English words every day for 3 months have 23% faster reaction speed in puzzle-solving tasks than those who seldom memorize actively. Memorizing basic knowledge regularly keeps our brain sharp, just like doing exercise to build up our body.

We need to memorize things
2024年一项针对本市200名中学生的调查发现，连续3个月坚持每天背诵10个英语单词的学生，在解谜类任务中的反应速度比很少主动记忆的学生快23%。定期记忆基础知识能让我们的大脑保持敏锐，就像通过锻炼来增强体质一样。
