Reading Comprehension

　　Cloning technology made its first leap from science fiction to science fact in 1997. That year, Scottish researcher lan Wilmut created the world's first animal clone：a sheep named Dolly. In making Dolly, Wilmut defied(对…挑战) nature because Dolly was produced without the union of male and female sex cells.

The method that Wilmut used to create Dolly is neither a top-secret nor hard to understand. First, he removed an egg cell from an adult female sheep. Then, he used a fine needle to suck out(吸出) the egg' s nucleus(细胞核), the structure that houses a cell' s DNA(deoxyribonucleic acid(脱氧核糖核酸). DNA contains the biological material that determines what an organism looks like and how it functions.

　　Next, Wilmut removed a skin cell from another sheep－the sheep he wished to copy. Placing the empty egg cell and the skin cell side by side, he forced the two cells to fuse by zapping(用辐射线照射) them with a charge(电荷) of electricity. By doing that, Wilmut created an egg from one animal that contained the DNA of another.

　　The new egg cell divided and developed into an embryo(胚胎). Wilmut then implanted(移植) the embryo in he womb(子宫). In time, the embryo developed into a lamb sheep－Dolly.

　　For years later, a whole barnyard of animal clone, including sheep, mice, cows, pigs, and goats, has, come to life in labs around the globe. Now, the race is on how to produce the first human clone although many people are strongly against it.

Increasing Your Reading Rate

　　Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.

　　As your eyes move along the line of print, they make fixations (注视) or pauses (停顿) . It is important that you see several words at a fixation. It is also important that your eyes leave a group of words quickly and move on to another group. The number of letters or words that you see at a fixation are called your eye span (视幅、视跨). Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.

　　The way in which you read always depends on what you are reading and for what purpose (目的) . You should know the different ways of reading so that you can apply whatever method that is necessary. Here are four ways of reading, but not all, they may increase your reading rate.

　　1．Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You may skim to find a lost place of a statement that you have read and cannot recall. You may skim to get an idea of a story.

　　2．Rapid first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.

　　3．You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive study of the main subject of your school curriculum (课程), solving arithmetic problems, studying rules for playing a game, or reading directions .

　　4．Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing material that you already know well.

1．A fast reader can get the ideas ________ a slow reader can.

[　　]

2．In this passage, “eye span” means ________.

[　　]

A．eyesight

B．a group of words

C．the number of letters or words you see at a fixation

D．your reading speed

3．The way of reading always depends on ________.

[　　]

4．The word “Skimming” means ________.

[　　]

5．Careful reading is an important kinds of reading ________.

[　　]

A．when you read a story for enjoyment

B．when you review a lesson that you already know well

C．when you read the directions before using a camera which is expensive

D．when yon wish to find a lost place that you have read

Do you know that a fast reader can get the ideas better than a slow reader can? Of course, you save time by reading fast, but this is not the main reason for fast reading. The main reason is that you understand better what you are reading when you read fast.
As your eyes move along the line of point, they make fixations (固定) or pauses (暂停). It is important that you see several words at a fixation. It is also important that your eyes leave a group. The numbers of letters or words that you see at a fixation are called your eye span (视跨). Pay more attention to improving your rate of reading. With practice you can learn to read faster than you usually read.
The way in which you read always depends on (取决于) what you are reading and for what purpose. You should know the different ways of reading so that you can apply whatever method is necessary. Here are four ways of reading:
(1) Skimming is an important kind of reading. This method can be used when you wish to review something that you have forgotten. You can skim to get the main points.
(2) Rapid (快速) first reading and then rereading certain parts carefully is important. You may use this type of reading to study a science lesson or a history lesson.
(3) You need to do careful reading and rereading sometimes. This type of reading is necessary for making an intensive (细致的) study of your school subjects, solving math problems or reading directions.
(4) Rapid reading is used when reading stories for enjoyment. You may also do rapid reading when reviewing materials that you already know well.
