(58)生物：第12篇（Frogs蛙）---难度级别：$$+ X. Y) x6 z, k$ `5 B8 H
If you liked the colorful animal we just saw, you`re going to love these next animals. Frogs. You might not normally think of frogs (as) being colorful, but these frogs definitely are. They are the (dart-poison) frogs喷射毒液的蛙 (of) Central and South American. Look at (these) striking colors---often yellow with black stripes or deep blue with black (spots斑点). & a# Q4 i9 g!

When (threatened), these frogs secrete a (substance through) their skin that would easily kill whatever animal might try to eat them. Their bright colors communicate this, and so most animals tend not to hunt them.1 _" [& f1 O3 g6 l) u1 }# N

Now, speak of hunting, for centuries these frogs were (sought-after<adj>受欢迎的) by hunters. As you might think, the hunters didn`t want to eat the frogs, (but rather, they) captured them for their <poison>. They would add the poison to the tips (of) their hunting (arrows箭)---of course, nowadays most hunters use guns. 6 Y7 y& | C! B% c

Researchers believe that they can make new heart medicine from the poison, because it acts as a <stimulant> on the body`s nervous <system>. Researchers think (they) could use (it to) stimulate (a weak heart).[连读]

There is, however, a problem with doing research on these frogs. Those that (are caught in the wild) will produce the poison until they die. However, those that (are born) captivity, like the ones you see here, will not produce any poison at all.

I`d like to begin by thanking Dr. Kane for inviting me to be here today. Although I`m not a geologist, I have been collecting minerals for years. My collection is really diverse because I`ve traveled all over the world to find them. Today I`ve brought a few specimens for you to see. After I discuss each one, I`ll pass it around so that you can look at it more closely. . y- e3 \) l) [, s1 t$ X9 w

Notice that they are varied color from white to pink to red. These (glassy光亮的，像玻璃般光滑的) one is found in <volcanic> rock---in fact, I found (it in) new (Mexico墨西哥) on a collecting trip.

These final samples are all (plagioclase斜长石 feldspars). Many plagioclases are very rare, so I`m particular (pround of) my <variety> (in) my collection. I`ve also brought a few (slides of some) large samples, and if you`ll turn (out the light) now, I`d like to show them to you.
