1．There are cuntless articles telling us hw the Internet has made ur lives mre cnvenient.
[句式分析] 本句的主干是There are cuntless articles；telling us hw the Internet has made ur lives mre cnvenient为现在分词短语作定语，修饰articles，其中hw the Internet has made ur lives mre cnvenient为宾语从句，作tell的直接宾语。

2．At age 50，she fund herself ut f wrk and stuck at hme with nly her cmputer t keep her cmpany.
[句式分析] 此句为“find＋宾语＋宾补”结构，ut f wrk和stuck at hme是句子的宾语补足语，说明宾语herself的处境。with nly her cmputer t keep her cmpany是“with ＋名词＋t d”结构，在句中作stuck的伴随状语。

3．She realised that ne f the greatest benefits f the Internet was its ability t remve the distance that usually exists between peple.

4．She was s inspired by the peple she met nline that she decided t start an IT club t teach lder peple hw t use cmputers and the Internet.

5．She believes that it is highly imprtant t bridge the digital divide and make sure that everyne has access t the Internet and knws hw t use new technlgy.
[句式分析] 本句是复合句，含有两个谓语，分别是believes和knws；第一个动词believes之后由that引导了一个宾语从句，宾语从句中it是形式主语，真正的主语是t bridge the digital divide and make sure that everyne has access t the Internet，其中that everyne has access t the Internet作make sure的宾语。第二个动词knws 后的hw t use new technlgy是其宾语。
[自主翻译] 她认为，消除数字鸿沟、确保人人都能使用互联网并且知晓如何运用新技术，是非常重要的。

The technlgy wrks when cmbined with the cmputing device tward the user’s face.After making sure f the user’s eye mvements，the technlgy is then able t easily find where a persn’s eyes are mving，and then allw the eyes t cntrl a cursr(光标)．
“Our sftware can then determine the lcatin f the eyes and knw where yu’re lking n the screen t make sure what yu’re lking at，” reads an explanatin n The Eye Tribe site.
