该句中包含有三个定语从句。
Whenthekillerwhales,or“killers”astheywerethencalled,helpedthewhalerscatchthebaleenwhales是关系副词when引导的定语从句，修饰先行词atime；astheywerethencalled是关系代词as引导的定语从句，意为“正如当时被叫做的”，修饰先行词“killers”；thatwereontheirannualmigration是关系代词that引导的定语从句。
[练习]汉译英

2）那是一个没有收音机，没有电话，也没有电视的时期。
2.OntheafternoonIarrivedatthestation,asIwassortingoutmyaccommodation,Iheardaloudnoisecomingfromthebay.
本句为主从复合句，主句是Iheardaloudnoisecomingfromthebay；Iarrivedatthestation为省略了关系词that的定语从句；as在句中引导时间状语从句。
句中现在分词短语comingfromthebay作宾补。

3.IttookoverhalfanhourtogettheboatbacktoJames,andwhenweapproachhim,IsawJamesbeingfirmlyhelpupinthewaterbyOldTOM.

StepIII师导生学，互动探究（师生互动）
一、V-ing被动形式的构成（groupwork师导生学合作探究）
【观察探究】
V-ing一般时和一般时的被动形式;
1）Hehurriedhome,lookingbehindfromtimetotime.
2）Thebuildingbeingrepairedisourdormitory.
V-ing的完成时和完成时的被动形式
1）Havinglitacandle,shewentout.
2）Havingbeenaskedtostay,Icouldn’tleave.
3）Havingheardthis,ourteacherexpressedhersatisfaction.
【归纳总结】
如果v-ing与句中的逻辑主语构成被动关系，即当动词-ing形式的逻辑主语是动作的承受者时，需用其被动形式（beingdone，havingbeendone）。
其否定形式是：
notbeingdone,nothavingbeendone
V-ing形式表示的动作与主句谓语动词同时发生，用其一般式;V-ing形式表示的动作在主句谓语动词之前发生，用其完成时。
【即学即练】
人们不喜欢无缘无故的赞扬。
Peoplehatebeingpraisedfornothing.
这问题远没得到解决。
Theproblemisfarfrombeingsolved.
她不介意被一人留在家里。
Shedidn'tmindbeingleftaloneathome.
没有被邀请参加聚会，他感到很不高兴。
Hewasunhappyfornothavingbeeninvitedtotheparty.
尽管被告诉好多次了，但他仍然犯同样的错误。
Havingbeentoldmanytimes,hestillmadethesamemistakes.
二、v-ing被动形式的语法功能（互动交流，突破疑难）
1.作主语
Swimmingisgoodforhealth.
