近义词解析:重叠

📚 核心概念

1. overlap (部分重叠)

Our working hours overlap by two hours.
我们的工作时间重叠了两小时。

2. coincide (完全重合)

Our opinions coincide on this issue.
在这个问题上我们的观点完全一致

3. intersect (交叉重叠)

The two lines intersect at point A.
两条线在A点相交

4. converge (汇聚重叠)

All evidence converges to the same conclusion.
所有证据都指向同一个结论。

💡 顾老师提示:这些词都表示"重叠"概念,但侧重点不同:overlap强调部分重叠,coincide强调完全一致,intersect强调交叉点,converge强调向同一点汇聚。

🔊 发音指导

overlap发音:/ˈəʊvəlæp/ [ˈoʊvərlæp]

coincide发音:/ˌkəʊɪnˈsaɪd/ [ˌkoʊɪnˈsaɪd]

发音要点:

  • overlap重音在第一个音节,注意"lap"发音要清晰
  • coincide重音在第三个音节,注意"cide"发/saɪd/
  • intersect注意"ter"的卷舌音
  • converge注意"ver"发/vər/音

中文谐音参考:

overlap:欧-沃-莱普

coincide:扣-因-赛德

💡 顾老师纠音:常见发音错误:

  • 把overlap读成"over-lap"(正确:[ˈoʊvərlæp]
  • 忽略coincide的第三个音节重音
  • 混淆intersect和intercept的发音

🎯 用法对比

1. overlap vs coincide → 部分重叠vs完全重合

Our vacations overlap by 3 days (部分重叠) vs Our birthdays coincide this year (完全重合).

2. intersect vs converge → 交叉vs汇聚

The roads intersect at the square (交叉) vs The rivers converge here (汇聚).

3. 时间/空间/概念上的重叠

The two events overlapped in time (时间) vs Their research areas intersect (领域) vs Our ideas converge on this point (观点).

语法注意:

  • overlap可作名词和动词
  • coincide是不及物动词,需接with
  • intersect多用于几何和空间关系
  • converge常与on/toward连用

📝 随堂练习

1. 选择合适的词填空:

a) Our schedules ___ by one hour. (overlap/coincide)
b) The two circles ___ at two points. (intersect/converge)

2. 听录音跟读:

overlap:[ˈoʊvərlæp] → The two projects overlap in scope.

coincide:[ˌkoʊɪnˈsaɪd] → Our views coincide perfectly.

3. 改错:找出使用不当的词

原句:The two lines coincide at the center.(应用intersect)

正确:The two lines intersect at the center.
