Step 5 Sentence fcus
1．Having cllected and evaluated the infrmatin，I help ther scientists t predict where lava frm the vlcan will flw next and hw fast.(P34)
收集和评估了这些信息之后，我就帮助其他科学家一起预测下次火山熔岩将往何处流去，流速是多少。
Having cllected and evaluated the infrmatin是现在分词短语，在句中用作时间状语，相当于一个由when 引导的时间状语从句When I have cllected and evaluated the infrmatin。现在分词短语在句中还可以用作原因状语、让步状语等等。如：
(1)Having wrked hard all day，I went t bed early.
＝Because I had wrked hard all day，I went t bed early.
(2)Having been tld many times，he still repeated the same mistakes.
＝Thugh he had been tld many times，he still repeated the same mistakes.
另外，predict后是由where和hw引导的两个宾语从句。
2．I was abut t g back t sleep when suddenly my bedrm became as bright as day.(P34)
我刚要再睡，突然我的卧室亮如白昼。
be abut 意为“正要……这时……”，其中when相当于at this/that time，类似的句式还有be “正在做……突然……”；had “刚做完……这时(那时)……”。例如：[来源:学&科&网]
(1)The sprts meeting was abut t begin when it rained heavily.
运动会刚要开始，这时天开始下起了大雨。
(2)I was reading when he brke in.我正在读书，他突然闯了进来。
3．The ther tw climbed dwn int the crater t cllect sme lava fr later study，but this being my first experience，I stayed at the tp and watched them.(P35)
另外两个人攀下火山口去收集供日后研究的岩浆，但是我是第一次经历这样的事，所以留在山顶上观察他们。
this being my first experience 是独立主格结构，在句中作原因状语。再如：
It being a very ht day，we decided t g swimming.
＝Because it was a very ht day，we decided t g swimming.
