在森林中一旦遭遇火灾,下列做法正确的是

A.使用沾湿的毛巾遮住口鼻,顺风逃离

B.如果火势减弱,则可休息

C.选择低洼地或坑洞躲避

D.伺机逆风突破林火包围

答案

答案:D

本题考查自然灾害的防御。在森林火灾中受伤,主要是由火烧灼、烟熏烫导致皮肤、呼吸系统等损坏所致。“顺风逃离”错误,人在森林中奔跑速度不会快于火势顺风蔓延的速度;“火势突然减弱”往往只是暂时,随后风助火威,必有大火突起,火险之地,不可片刻逗留;低洼、坑洞是最难逃生的死地。因此A,B、C三项断不可取。选择火势弱处、逆风迅速突破火线才能化险为夷。

The comprehension passages on this course are designed to help you increase your speed. A higher reading rate, with no loss of comprehension, will help you in other subjects as well as English, and the general principles apply to any language. Naturally, you will read every book at the same speed. You would expect to read a newspaper, for example, much more rapidly than a physics or economics textbook but you can raise your average reading speed over the whole range of materials you wish to cover so that the percentage gain will be the same whatever kind of reading you are concerned with.

The reading passages which follow are all of an average level of difficulty for your stage of instruction.

If you get to the point where you can read books of average difficulty at between 40 and 50 w.p.m. with 70% or more comprehension, you will be doing quite well, though of course any further improvement of speed with comprehension will be a good thing.

When you practice reading with passages shorter than book length, do not try to take in each word separately, one after the other. It is much more difficult to grasp the broad theme of the passage this way, and you will also get stuck on individual words which may not be absolutely essential to a general understanding of the passage. It is a good idea to skim through the passage very quickly first (say 500 words in a minute or so) to get the general idea of each paragraph. Titles, paragraph headings and emphasized words (underlined or in italics) can be a great help in getting this skeleton outline of the passage.

The author suggests that you should not read passages word by word because ().

A. it is not necessary to do so

B. it might simply slow down your reading speed

C. it might be more difficult to catch the general idea of the passages

D. it will result in misunderstanding
