5 E) M( Z5 I4 Y" }# TListen to a discussion between two students who are reviewing their notes from a lecture on insect behavior. Let’s see we should probably start our reviewing in (the) four stages the ants go to, you know when they developing from the eggs, yeah, I wrote that down on somewhere on my notes, oh, I got it right here, let’s see, they start off the eggs, the ants lays the eggs after, I don’t remember exactly how long they turn, oh yeah, the eggs are very tiny and they hatch in a few days and become <larvae>, and then they turn into (pupae{n.蛹}), that’s (one not move) at all and then they, I remember something interesting of the (pupae) stage that’s before they (are) full (in) mature, and they can get captured by other ants and they become sort of slaves in other ants colony, yeah, Dr. Lucy even use the term slave maker ants, they’ll be slave maker ants (but) go into other nests and steal the (pupae), so when the (pupae) going to adults they are (like) the slave of the other ants, and these slaves, they actually do the work (as) the other ants would (have) to do themselves, right, most of the slave maker ants they could do the work for themselves, couldn’t they, I guess so, but then, there are those Amazon ants, the Amazon ants, oh, those were the slave maker ants that are actually depended on the ants (they) slaved, (now) where we start again, let me see, here it is, the size of their (mandible{n.颚}), it was because that they (have these) really long curvy (mandibles), oh yeah, those (are the) jaws, right, and those are so big that the Amazon ants can’t even get their own food or dig the nests for themselves, so they need the slaves to get the food and dig the nests for them, that make sense, could we go back to the part on how they capture the slaves, we were talking before about how some slave maker ants going into other nest
+ f8 H5 l4 @6 n+ k3 ?+ `5 y9 Sand bring back (pupae) to become slave, but they can also take (over) a whole colony, right, the queen ant (after) she mates, she is carrying her own eggs and what she does is she goes into another colony of another species, she takes over the colony and those other ants and the slaves start working for her and then she lays her eggs, but the colony she invaded is already got (it’s own) queen, if she cooperate, the slave maker will kill that queen and then (when) she (has) her own eggs, they become adults and they become slave maker ants too, and they go out (to rob) other ants nest for (pupae) to bring back and then slave.$ w* F5 i& g/ r1 [9 u9 {/ [

Listen to a lecture on an (ornithology{n.鸟类学，鸟学论文}) class, you know, it’s kind of fashionable among students of birds study rare and exotic species, especially endanger ones like golden eagles or (spotted owls), but I often think that everyday-birds, birds that (really) are part of our lives are simply overlooked, so I’d like spend some time talking about a very common bird, black crows, it might surprise you to know that crows are among the most challenging (birds) to observe and study, first of all, they look alike, picking (out) one or several individual craws in the flock (in) finding them again later is almost impossible, people study in larger animals can put some kind of mark on them so they can tell them apart, well, you can trap a large animal like a bear, (in a) mobilize (or a tranquilized {v.使镇定} gun), then it’s easy to put (a) tag on it, and try doing that to a craw you’ll probably kill it, secondly, craws are highly intelligent <survivors>, they adapt easily (to) wildly varying situations, this adds (to) the difficulty (of) studying (in) them, because they pick up so many individual (allies) habits, so you can never be sure (about) any conclusion you reach about crows from observing them applies to the whole species or just those particular crows you have been watching, one general (observation)$ H: Z5 h4 l" n' l" Q# n' S
about craws that can’t be made with a reasonable degree of certainty is that in the last forty years, more and more crows have been found living in large cities, they are (attracted) by people who produce a (normal) surmounts{v. 战胜, 克服, 超越} of garbage and (leave them) in places that craws can easily get to, it make (for) distances (they must travel to) hunt a lot (shorter).# j% h; u4 z5 ?+ l: ]& G5 p
