知识探究
★Although many students like to watch sports, game shows are the most popular．
【自主探究】　although的用法：
◆用作连词，意为“虽然；尽管；即使”，引导让步状语从句，相当于though。
◆although/though与but不能用于同一个句子中。
◆although引导的从句，既可放在主句前，也可放在主句后。若置于主句前，多用逗号与主句隔开。
【习题演练】
(　A　)1． 　　 they are twin brothers, 　　 they don't look like each other．
A．Although; / B．Although; but
C．But; although D．But; /
★… but we think the best way to relax is through exercise．
【自主探究】　through用作介词，此处意为“以；凭借”。如：
He went to a good high school through hard work．他凭借努力学习上了一所好高中。
★through还可表示“穿过”，与over和across的区别如下：
through 通过；穿过 强调从某个空间内部穿过，如forest，window等
across 横过；横穿 强调从物体的表面横过，从一边到另一边，如street，road，playground等
over 越过 强调从某物的上方越过
【习题演练】
2．用through，over和across填空。
(1)A plane flew over the house．
(2)It took us three days to go through the forest．
(3)Please be careful when you go across the street．
★However， she has some bad habits, too．
【自主探究】　however是副词，意为“然而；不过”，表示转折，不与but连用。一般情况下，however放句子开头，后用逗号隔开。
【习题演练】
3．他过着艰苦的生活，但他感到很开心。
He lives a hard life．However， he feels very happy．
