【句式剖析】“while the cuntry is quite beautiful and has much natural wealth”在本句中是让步状语从句。【归纳拓展】while作连词时的主要用法：(1)其意为“当……的时候”，引导时间状语从句。这时，从句的时态通常用进行时态。
(2)其意为“但是，可是”，用作并列连词，表示对比，用于连接两个并列句，放在两个并列句之间。(3)其意为“虽然；尽管”，表示让步，引导让步状语从句。She was cking while she was keeping an eye n her baby sleeping in the cradle.她一边做饭，一边留意睡在摇篮里的婴儿。

【归纳拓展】(1)since可表示“既然，因为”，引导原因状语从句。Since n ne is against the plan，we will carry it ut.既然没有人反对这个计划，我们将执行它。(2)在含有since引导的时间状语从句的复合句中，主句通常用现在完成时、过去完成时或一般现在时。这时，since意为“自从……以来”，可以用作连词、介词或副词。
(3)since所引导的从句中的谓语动词为非延续性动词时，表示主句中的动作从since引导的从句中的动作发生持续到现在；若从句中的谓语动词为延续性动词，表示主句中的动作从since引导的从句中的动作结束持续到现在。It is ten years since they married.他们结婚到现在10年了。I haven’t played rugby since I left university.我大学毕业后就没打过橄榄球。

3．(P44)Nw，nt nly are Tanzanians helped by the hspital，but peple in neighburing cuntries are helped as well.【翻译】现在，不仅坦桑尼亚人得到了医院的帮助，邻国的人们也得到了帮助。【句式剖析】“nt nly are Tanzanians helped by the hspital”是部分倒装。其中的are提前放在了主语Tanzanians的前面。否定副词作状语，置于句首时，句子需用部分倒装结构，即把助动词、情态动词或系动词be提到主语之前。
【归纳拓展】(1)否定词置于句首，要用部分倒装，即把谓语动词的一部分(助动词、情态动词或be动词)提到主语之前。这类否定词或含有否定意义的短语主要有：n，nt，never，little，hardly，seldm，scarcely，barely，nt until，，nt als...，n ，，in n sense，in n way，in n case，by n means，under n accunt/ cnsideratin，at n time，under n circumstances等。
(2)当here，there，up，dwn，away，ff，nw，then，in，ut等表示方位或位置变化的副词放在句首，且谓语是表示存在的动词(如lie，live，sit，stand)或cme，g，rise等动词并且主语是名词时，句子一般要完全倒装，即把谓语动词整个提到主语前。这类句子比自然语序的句子更为生动、形象。但如果主语是代词时，即使把这些词放在句首，也不倒装。
(3)使用倒装句时应注意：①nt until所在的从句不倒装，主句要倒装。②nt als...连接两个并列句时，前者倒装后者不倒装。③连接并列句子时，因为neither与nr都是否定意义的词，前后两句都用倒装语序。
There she ges.她走了。Away flew the bird.那只鸟飞走了。Nw，here ges the stry.这个故事是这样的。
Here cmes my list f ds and dn’ts.这里我列举一些注意事项(“应该”和“不应该”做的事)。Nt a single mistake did he make in yesterday’s exam.在昨天的考试中他没有犯一个错误。Hardly had I finished the wrk when the telephne rang.我刚完成工作，电话铃就响了。
