是否也曾纠结“30到40的英文怎么写” 明明学过却总拼错,比如把forty写成fourty别慌!这篇文章小编将不仅解决数字拼写,更覆盖年龄表达、发音陷阱和实用场景,一次性扫清所有困惑!
一、30-40的标准写法与发音
strong>逐个数字解析:
0: thirty(/θti/)
1-39: 连字符+个位数(例:35=thirty-five)
0: forty(/fti/) 注意:无”u”(非fourty)!
strong>规律:除20/30/40/50/80独特,其余整十数=个位数+ty(如60=sixty)
strong>发音避坑指南:
strong>30 vs 13:thirty(θ)≠ thirteen(θtin)
strong>40 vs 14:forty(fti)≠ fourteen(ftin)
二、高频错误与纠正(重点!)
「forty和fourty哪个正确」
案:forty是唯一正确拼写! fourty是典型错误,源于four(4)的干扰。
strong>错误根源:
文“四”影响英文思考,误加“u”;
淆制度:four→fourteen(有u),但forty无u!
strong>同类错误:
ifty(50)≠ fivety
inety(90)≠ ninty
三、年龄与场景表达实战
strong>直接年龄:
he is thirty years old(口语可省years old)
雷:不说”I have 30 years old”(需用be动词)
strong>年龄段表达:
strong>in one’s thirties:30-39岁
分:early thirties(30-33)、mid-thirties(34-36)、late thirties(37-39)
:He became a CEO in his late thirties(他快40岁时当上CEO)
strong>文化差异:
年龄避免直接”How old are you”,改用:
Could you share which age group you fall into”(更礼貌)
四、数字在生活中的应用
strong>时刻表达:
:30 → nine thirty(非half past nine)
:40 → two forty(美式常用)
strong>序数词转换:
0th = thirtieth(非thirtyth)
0th = fortieth
strong>大数字制度:
,345 → one thousand, three hundred and forty-five
位一断:千(thousand)、百万(million)
独家建议:3步永久记住拼写
strong>口诀法:
Four有u,forty无;
ive变fifty,nine变ninety!”
strong>对比表格强化记忆:
