True, GM foods are already very much a part of our lives (已成为我们 生活的一部分), and farmers have a strong incentive to (迫切地想要) use the biotechnology as it can raise overall crop productivity (能提高稻谷 产量), yet we need a deep philosophical discussion of its implication. We still remember that when pesticides were first introduced, they also were praised as absolutely safe and as a miracle cure for farmers. But for all that promise (尽管这么多保证), decades later the technology revealed its truer lethal implications. Hence, any technology should be subjected to rigorous testing (应该进行严格的测试) before its wide application.

在这之前,往往需要争分夺秒地利用正确的软件补丁来防止破坏的发生。

3 最简单的钓鱼骗局试图利用迅速致富的伎俩诱使诈骗目标寄钱。

但网络骗子们也变得越来越狡猾,最近的陷阱是通过发送客户服务的电子邮件让用户进入假银行或商业网站,并在那里请他们“重新输入”他们的账户信息。

4间谍软件与垃圾邮件和钓鱼网络一起,构成了三个令人生厌的互联网害虫。

尽管有些程序可以通过入侵软件漏洞从而进入电脑,但这些有害而秘密的程序通常会随着其他免费的应用软件侵入到计算机系统中。

5 尽管因特网已经彻底改变了全球通讯,但是对于那些利用网络力量实现罪恶目的的人和那些负责阻止这些网络犯罪的人来说,他们之间的较量才刚刚开始。

2 由于云计算可以用来不断提供资源,因此当你需要扩充计算机容量时就不需要去买硬件,就不会因为用电去冷却计算机设备而产生更多的二氧化碳。

3 这意味着他们不需要开车到办公地点。

这就可以省去燃料费,减少二氧化碳排放,从而保护了环境。

4 万一断电,客户可以在电脑再启动时使用和主机同步的备份。

5 除此之外,云计算还不容易受到黑客入侵和分布式拒绝服务的攻击,因为攻击者不知道数据的位置。

2目前云计算技术涉及一个数据中心的存在,这个中心能够为全世界用户提供服务。

3这就减少了由于没有硬件,如手提电脑带来的影响。

4虚拟化可以使一个损坏的云端服务器迅速找到替代品而不造成大的损失或破坏。

5云技术还处于起步阶段,更多新的优点会不断被发现。
