[译] 由于下雨，我们停止发射卫星。
[误] Because it's raining, we stopped launching the manmade satellite.

[正] As it's raining, we stopped launching the manmade satellite.
[注] 原因明显或认为人们已经知道原因时，最好使用连词 as, since 或 seeing that, 而不用 because, 又如: As he wasn't ready in time, we went without him to make an investigation. 由于他未及时做好准备，我们没有带他去考察。反之则用 because, 如: Mr Smith was absent because he was ill. 史密斯先生没来，因为他生病了。
