七、教学过程
一）.难句分析：
1.The science facilities ar e very good with laboratories that have all the latest equipment.
这些科研设备非常好，实验室配有最新的设备。
【巧解句构】 with在此句中意思为“带有……”，其引导的短语对句子作附加说明，that have all the latest equipment为定语从句，修饰laboratories。 [本文由www.免费提供]
2....and these are always very interesting，as the lectures are people who have made real discoveries in their areas of science.
这些讲座总是很有趣的，因为作讲座的人是在各自的科研领域里真正有所发现的人。
【巧解句构】 as conj.“因为，由于”，在本句中引导原因状语从句。as作连词可以引导多种状语从句，主要有时间、原因、方式、比较、让步等从句。
3.The Nobel Prize is the highest scient ific prize there is，so we should be very proud of that.
诺贝尔奖是目前科学方面的最高奖，因此我们为此感到骄傲。
【巧解句构】 there is为定语从句，修饰prize。
4.It is important to know how they r eact with different substances，for example，water and oxygen.
了解它们如何同像水、氧气这样的物质发生反应的是非常重要的。
【巧解句构】 1)it是形式主语，真正的主语是动词不定式to后面的部分。
2）how引导的句子作know的宾语。
【要点剖析】react with同……发生反应。
for example是不完全列举，“例如”。完全列举时用that is。
拓展延伸注意此处空半格以it作形式主语或形式宾语的动 词有feel，consider，find， believe，make， take，imagine，think，suppose，count，regard等。在这种结构中，被替代的成分要置于句尾。
5.Leave the tube for one week. 把试管放置一个星期。
【要点剖析】1)leave意为“维持，使保持一定 状态”，允许在某一种状态。
2)leave作“离开”讲时是及物动词；作“去，出发”讲时，是不及物动词；
还可作“遗忘，忘掉”讲，与forget近义，但 搭配不一样，leave sth.+地点状语，而forget只加sth.,不加地点。如：
I left my dictionary in my dormitory.
I forgot my dictionary.
拓展延伸 注意此处空半格leave作“维持，是保持某一状态”讲时，其结构经常是：后跟副词、分词、介词、形容词等作宾语补足语的复合结构。如：?
I am sorry I h ave left you waiting for me for so long time.?
His answer lef t me unhappy.
6．Our chemistry teacher，Mr Longford，takes us to public science lectures about four times a term，and these are always very interesting，as the lecturers are people who have made real discoveries in the area of science.
我们的化学老师朗福德先生，大约每学期带我们去听四次大众科学讲座，这些讲座是非常有趣的，因为作讲座的人在他们所从事的科学领域都有实际的发明。
【巧解句构】 1）这句话是由and连接的两个并列句子，连个句子的主语分别是：our chemistry teacher和 these。后 面的句子又是一个由as连接的原因状语从句，表示明显的原因，意为“由于、鉴于”。 轻轻告诉你
He that seeks gains. 有所求则有所获。
2)Mr Longford作 our chemistry teacher的同位语。
拓展延伸 注意此处空半格1） as除了引导原因状语从句外，还经常引导时间状语从句。在此用法上，应注意同when和while的区别。?
when表示某个具体的时间，所引导的从句的动作或与主语的动作同时发生，或先于主语的动作发生，when可指一段时间，也可指点时间，既可表示一时性的动作，也可表示持续性的动作。?
while只表示持续性的动作或状态，不能表示一时性的动作或短暂动作。?
as所表示的动作与主句的动作同时发生，具有延续含义，一般同延续性动词连用。as，while可译为“一边……一边 ……”，as还有”随着……”的意思。?
2）as引导让步状语从句作“尽管”讲时，须倒装，即把强调的部分（多为名词、形容词、副词）放句首，当所强调的表语是单数名词时，须把不定冠词去掉。
