DoyoufeelpessimisticoroptimisticaboutthefutureoftheInternet?

Why?

Languagepoints

1.In1983,therewereonly200computersconnectedtotheInternet.

=whichwereconnectedtotheInternet.

computer和connect是被动关系,因此connectedto是过去分词做定语来修饰computer,相当于一个定语从句。

Itissurprisingthattherewere3oogoldcoinsburiedunderground.

＝whichwereburiedunderground.

真是令人惊奇，地下埋了300枚金币。

Therearesomanypeoplewatchingthebigfireinthestreet.

=whowatchedthebigfireinthestreet.

People和watching是主动关系watching是现在分词做定语表主动来修饰people相当于定语从句。

2.Someexpertsarepessimisticaboutthefuture.

一些科学家对（计算机主宰的）未来表现出悲观的态度。

bepessimistic/optimisticabout对…悲观/乐观

I’mratherpessimisticaboutthepresentsituation.

我对目前的局势感到悲观。

3.ItisclearthatwearegoingtoseeanexplosionofshoppingontheInternet.

很显然，不远的将来我们就会看到网上购物的狂潮。

It作形式主语，真实主语是that引出的主语从句。

＝thatwearegoingtoseeanexplosionofshoppingontheInternetisclear.

ItisclearthatinthenextfewyearstheEarth’sclimatewillchange.

=ThatinthenextfewyearstheEarth’sclimatewillchange.

4...theuseofcomputerswithsoundsandpicturesthatmakeyoufeelasifyouareinarealsituation.

（虚拟世界）是计算机通过声音和图像模拟现实，以使人感到仿佛置身于一个真实的空间。
