句子结构分析及特殊词的用法
1.However ,a comparison with data for weeks when there was no experimentation showed that output always went up on Monday.此句中的主谓宾分别是什么？尤其是with和when的用法和结构？
2.These suggests that dimmer bulbs burn longer,that there is an anvantage in  not being too bright.此句中，第二个that的用法，做什么成分，为什么要用that？

Answer

1. However, a comparison with data for weeks when there was no experimentation showed that output always went up on Monday.
主語 = a comparison；動詞 = showed；賓語 = that output always went up on Monday (以關係從句[relative clause]表示)
"with data for weeks" 乃 前置詞片語 (prepositional phrase) 
"when there was no experimentation" 是修飾「星期(weeks)」的 關係從句。

2.These suggests that dimmer bulbs burn longer, that there is an advantage in not being too bright.
個人認為，此關係從句 -- "that there is an advantage in not being too bright" -- 大概是連接著主語 "These suggests ..."，所以才用上 "that" 這關係代詞。

補：
1) 優點是 advantage (不是 anvantage)。
2) 每個標點符號後須隔一空格 (而不是在標點符號前隔空格)。
