W： Hi Leo， why do you say English would become the world language？
M： Well。 For one thing， it’s so commonly used， the only language that is used by more people is Chinese。
W： Why is English spoken by so many people？
M： It’s spoken in many countries of the world because of the British empire。 And now of course is the influence of America as well。
W： Many students find English a difficult language to learn。
M： Oh， all languages are difficult to learn。 But English does have two greatest advantages。
W： What are they？
M： Well， first of all， it has a very international vocabulary。 It has many German， Dutch， French， Spanish and Italian words in it。 So speakers of those languages will find many familiar words in English。 In fact， English has words for many other languages as well。
W： Why is that？
M： Well， partly because English speakers have travelled a lot， they bring back words with them。 So English really does have an international vocabulary。
W： And what is the other advantage of English？
M： It that English grammar is really quite easy。 For example， it doesn’t have dozens of different endings for its nouns， adjectives and verbs， not like Latin， Russian and German for example。
W： Why is that？
M： Well， it’s quite interesting actually， it’s because of the French。 When the French ruled England， French was the official language， and only the common people spoke English。 They tried to make their language as simple as possible。 So they made the grammar easier。

Why, you may wonder, should spiders be our friends？
Because they protect so many insects, and insects include【M1】______
some of the greatest enemies of the human race. Insects
would make impossible for us to live in the world; they 【M2】______
would ruin all our crops and kill our flocks and herds,
as it were not for the protection we get from insect 【M3】______
-eating animals. We owe a lot for the birds and beasts 【M4】______
who cat insects but all of them put together kill only
a fraction of the amount destroyed by spiders. Moreover, 【M5】______
unlike some of the insect-eaters, spiders never make 【M6】______
the least harm to us or our belongings.
Spiders are not insects, as many people think, and 【M7】______
or even nearly related to them. One can tell the difference
almost at a glance, for a spider always has eight
legs but an insect never more than six.
How many spiders are joined in this work on our 【M8】______
behalf？ One authority on spiders made a census
of file spiders in a grass field in the south of
England, and he estimated that there were more
than 2,250,000 in one acre; that is anything 【M9】______
like 6,000,000 spiders of different kinds on
a football pitch. Spiders are busy least
half the year in killing insects. It has been
estimated that the weight of all the insects
destroyed by spiders in Britain in one year would
be greater than those of all the human beings 【M10】______
in the country.
【M1】

【填空题】再听录音或仔细阅读文本，并完成测验。 Programming Languages Student: Professor Martin, I just finished my Java assignment, but I still have some questions. Instructor: Sure, Andrew. Student: I’m having a hard time keeping all the languages straight. There are so many. Instructor: There are quite a few. Which ones are you having trouble with？ Student: All of them. I think it’s confusing to have all these （1）. Instructor: I see where you’re coming from. It’s a lot to learn. Student: But why are there so many different languages？ Instructor: The first reason is that it makes developing （2） easier.

But why are there so many human-readable programming languages？ Instructor: Some human-readable programming languages are more appropriate for certain kinds of software.
