KET 听力小提示口语里常缩读：I've / She's / They've。注意 She's 可能是 She is 也可能是 She has，听后面的动词判断：后面是名词/形容词=She is；后面是过去分词=She has。
别贪多：KET 阶段就到这for/since 表"持续多久"、have been to vs have gone to 的细微差别、非延续动词，这些都是 PET 的内容。现在先把 just/already/yet/ever/never 用熟，就是满分表现。
一个好记的总例子I've just sent you a message. Have you read it yet? — Not yet, but I've already checked my emails. 一句话把 just/yet/already 全用上了。
⑤ 场景全解：科技话题里怎么用
场景
例句
记忆点
1 刚做完某事
I've just sent you a message.
just 放 have 后
2 已经做了
She's already downloaded the app.
肯定句 already
3 还没做
Have you charged your phone yet? — Not yet.
yet 在句尾
4 问经历
Have you ever sent a real letter?
口语万能问句
5 否定经历
I've never used a laptop before.
never=从未
6 被动小节点
The phone is made of glass. / My bike was repaired.
be+过去分词，认识即可
被动小节点（点到为止）被动 = be + 过去分词，表示"被……"。KET 只需看懂两句：It's made of glass.（它由玻璃制成）、My phone was repaired.（我的手机被修好了）。不要求你会写复杂被动句，PET 再系统学。
被动常见两兄弟：made of / made in
搭配
意思
例句
be made of
由……制成（看得出材料）
The desk is made of wood.
be made in
在……制造（产地）
This phone is made in China.
⑥ 中国学生 5 大高频错误诊断
错误 1：he/she 后用 have ✗ She have finished her homework. → ✓ She has finished her homework. 第三人称单数用 has。
错误 2：过去分词写成过去式 ✗ I have went to Beijing. → ✓ I have been to Beijing. 完成时里用过去分词 been，不是 went。
错误 3：already / yet 位置放反 ✗ I have finished my homework already.（可接受，但更常见 yet 在否定句尾）/ ✗ Have you finished already? → ✓ Have you finished yet? already 肯定句中间；yet 否定/疑问句句尾。
错误 4：和过去时混用 ✗ I have seen him yesterday. → ✓ I saw him yesterday. / I 've seen him. 有 yesterday 具体时间，就用一般过去时。
错误 5：否定回答答错 ✗ — Have you ever been to Paris? — No, I don't. → ✓ No, I haven't. Have you…? 回答用 Yes, I have. / No, I haven't.
⑦ KET 考点与真题演练

Writing 邮件
写一次"科技经历"（发邮件/打电话）

真题风格演练（KET 出题方式）
真题风格 · Part 5完形：I can't play the game — I ___ (not finish) my homework ___. (yet / already)
haven't finished, yet。否定句 + 句尾用 yet。
真题风格 · Part 5选词：My sister has ___ to Shanghai. (been / went / go)
been。has 后面用过去分词 been。have been to = 去过。
真题风格 · Speaking考官问：Have you ever sent a text message to your teacher? 你怎么答？
参考：Yes, I have. I often send messages to my teacher about homework. / No, I haven't. I only talk to her at school.
