The invention of barcodes()is based on a very simple idea.We only need to give each
product a specific number and print it.1 We could simply print the number itself.But this can
cause problems.For example,an unclearly printed"seven"could look like a"one"to a computer.
It's also true for "three"and "eight".2 We need a better way of printing numbers so that they
can be read correctly at high speeds.That's the problem barcodes solve.
II
Each number in a barcode is shown by seven blocks of the same size.3For example,the
number "one"is shown in turn by two white stripes(),two black stripes,two white stripes,and
one black stripe.4
A barcode includes different parts and each one provides a specific meaning.The first part of a barcode tells
you the country where the product was made.For example,690-692 is the barcode for China.5 The
final part is about the product itself.This is how barcodes work.
A.Then computers can read it directly
B.All information can be shown by barcodes.
C.The next part tells you who produced the product.
D.And“nine”looks similar to“six”if you turn it upside down.
E.Even if you turn it upside down,it isn't similar to any other number.
F.These are colored either black or white to show the number zero to nine.
【答案与解析】
1.A。上文讲述了如何使用条形码，与其对应的应该是选项A“然后计算机可以直接读取”介绍接下来的
步骤。
2.D。上文介绍了仅仅打印数字会存在数字混淆的问题，选项D“如果你把它翻过来，‘9'看起来和‘6'很
像”符合语境。
3.F。下文举例数字“1”可以用白色和黑色的条来表示，选项F“它们被涂成黑色或白色来表示数字0到9
符合语境。
4.E。上文讲述了条形码用白色和黑色的条解决了数字混淆的问题，选项E“即使你把它颠倒过来，它也
和其他数字不一样”符合语境。
5.C.The first part of a barcode tells you the country where the product was made."The final part is about
the product itself.”可知，此处介绍条形码的最后部分，选项C“下一部分告诉你是谁生产的产品”符合语境。
