Tonight I`m going to talk about the most basic aspect of survival---the space suit. When most of you imagine the <astronaut>, that probably the first thing that comes to mind, right? Well, without space suits, it (would) not be possible for us to survive in space. For example, outer space is a (vacuum真空；真空般的状态)---there is no gravity or air (pressure); without protection, a body would explode. What`s more, we`d cookin the sun or freeze in the (shade阴凉处，阴影部分)---with temperatures (ranging) from a (toasty) 300 degrees above to a cool 300 degrees (below zero Fahrenheit华氏的). 9 u  o5 I! R3 i% `

The space suit that (NASA) has developed is truly (a marvel奇迹，令人惊奇的人或事). This photo (enlargement) ihere (is a life-size image of an actual) space suit <worn> by astronauts (on) the last space (shuttle往返车辆、飞机 mission任务；航太地面指挥中心). This part is the (torso躯干)---it`s made of seven extremely durable layers. This (thick insulation隔热(隔音、绝缘)材料) protects against temperature (extremes) and radiation. Next is what they called a “bladder囊” (of) oxygen---that`s (an inflatable可充气的 sac囊；液囊), filled with oxygen, to simulate模拟(atmospheric) pressure. This bladder presses against the body with same force (as) the Earth`s atmosphere (at sea level). The <innermost> layers provided liquid cooling and (ventilation<n.>通风；空气流通). (Despite不管，不顾，任凭) all the layers, the suit is flexible, allowing free movement so we can work.

, C4 O( r) M% N  j; g. QMost people think of (astronomers天文学家) as peole who spend their time in cold observatories (peering仔细地看，费力地看) through telescopes every night. In fact, a tipycal astronomer spends most of his or her time <analyzing> data and may only be at the telescopes (a few weeks) of the year. Some astronomers work on (purely theoretical problems) and never use a telescopes at all. ( _/ o3 y# r! w
+ L0 @( Z& y" o9 V
You might not know how rarely (images are viewed) directly through telescopes. The most common way to observe the skies is to photograh them. The process is very simple. Fisrt, a photograhic plate is (coated<v.>涂上一层；外加一层) with a light-sensitive <material>. The plate is (positioned<v>安放，放置) so (that the image received) by the telescopes is recorded on it. Then the image can (be) developed, enlarged, and published so that many people can study it.
9 Q, p# |8 S2 E7 k, @' m9 h' ?! t" R# w+ w
Because most (astronomical) objects are very (remote遥远的，久远的), the light we received from (them is rather feeble衰弱无力的，无效的). But by using a telescope as a camera, long time (exposures曝光；暴露；揭露) can be made. In this way, objects can be photograghed that are a hundred times (too faint模糊的；微弱的；轻微的) to be seen by just looking through a telescope.

8 Y4 w1 \+ c5 L0 }, m& Q+ A(Word comes from California of a new weapon in the war on household pests.) Two (scientists 人名原则！) working for (a firm in Anaheim), California, have developed a method to (eliminate排除，剔除) insects without using dangerous chemicals. The new poison? Hot air.1 Z  q. a9 l- N$ X- J8 S* w& Q

0 E2 a* F6 z4 u- d+ s/ d; kThe basic idea is (that) insects cannot adjust to temperatures much (above) normal. In <labratory> (experiments实验, cockroaches蟑螂 and termites白蚁) can`t survive much more than (a quarter of) an hour at 125 degrees(Fahrenheit), or about 50 degrees centigrade.
+ z% A1 f- V3 H' \2 z+ d3 ~+ ~% A9 W* H8 \9 H; z- U
The new method involves (covering a) house with huge tent帐篷 and filling (it) with air heated around (65) degrees centigrade. Hot air is forced使劲推、拉、挤 (in) with (fans), and the tent (keeps the) heat (inside) the house. Since termites try to escape by (hiding in) wooden beams, the heat (treatment) must be continued for (a full) 6 hours. But when it`s all over, and the insects are dead, there are no toxic (residues残留物) to (endanger危及，危害) humans or pets, and no (funny古怪的；有趣的) smells.
; l/ W0 E' |" H/ H- z
5 [; ~2 D% A5 tScientists (claim) that there is no danger (of) fire, either, since very few household materials (will) burn at 65 degrees centigrade. In fact, wood is prepared for construction use by drying it (in ovens烤箱) at 80 degree centigrade, which is<substantially相当多地，大大地> (hotter) than the air used (in this procedure过程；步骤；常规；应用程式).+ U; m: k+ ?+ x* V% v!

Before we start our first lab, I`d like to tell you a little bit about the workbook we`ll be using.* {1 ?, F' Z0 K7 O+ E  b

. l- }% ^  j, XThe first thing I`d like to point out is that the workbook contains a very large amount of material---far more (than) you could ever handle in a single semester. (What) you`re supposed to do is choose theexperiments (and) activities that you want to do--- (within a) certain (framework), of course. Part of my job is to help you make your choices.
5 A  K: a0 L6 h2 F6 u3 u0 v1 {$ L4 ~8 t7 t
Next, I`d like to mention that in each workbook chapter, there are usually two subsections. The first is called “Experiments” and the second is called “Activities”.. I1 p' Z# G( `+ `8 L/ V; [

We`ve just (seen two) contemporary large birds that can not fly: the (emu鸸鹋) and (ostrich鸵鸟). Over here (is an) interesting (specimen标本，样本from the past). This (stuffed填制的) animal is not (the giant penguin企鹅 it) appears to be, but an (auk(海鸦等)海雀), this particular kind of auk is very rare---only 78 (skins) are (known) to exist and most (are not) preserved as well as this one.The great auk, as you can see, was a rather large bird, and it couldn`t fly either. However, evidence suggests that the auk was (an excellent) swimmer and diver. Unfortunately, those abilities did not protect (it) from being easy <prey> for (hungry sailors) who years ago (sailed) the very cold and often (icy waters of Greenland,) Iceland, and (Scotland). In fact, (records) indicated that the auk was rather tasty and (that its) eggs---excuse me…that its eggs and feathers were useful as well. Still, it isn`t clear that what other factors (led to) the big bird `s demise死亡) around the 1844, the last time anyone reported (seeing) one. Of course, we believe it`s important to take extra (precautions预防，预防措施) to preserve the remaining great auks (skins). After all, these specimens should provde (invaluable非常宝贵的) for future <scientific> research. Does anyone have any questions before we move on our next (bird) exhibit?
