VOA慢速英语:Students' Writing and the Web: Motivator or OMG?

1.I think that text messaging has made students believe that it's far more acceptable than it actually is to just make screamingly atrocious spelling and grammatical errors.

这个句子不仔细看可能不太容易懂，不过， 如果注意到这两点就好了：首先，这里的it是形式主语，真正的主语是后面的不定式：to just make screamingly atrocious spelling and grammatical errors。其次，这是两者在对比，是哪两者之间呢？students believe和it actually is，学生认为的和实际上进行对比。

2.Professor Johnson suspects a strong link between the rise of instant and casual communication online and an increase in writing mistakes.

这句话是说教授怀疑两者之间存在联系。而这两者指的是rise of communication online和an increase in writing mistakes。

3.He says the actively changing nature of the Internet makes it difficult to stay current in studying its effects.

make后面接宾语补足语。

make用作使役动词表示 “使；使成为” 时，可跟复合结构，即“make+宾语+宾语补足语”，其中的宾语补足语可以是不带to的不定式、过去分词、形容词或名词。现将make的复合宾语结构小结如下：
     一、“make＋宾语＋n.” 意为“使、让某人 / 某物(成为)……”。如：
     We made him captain of our football team. 我们推选他作我们足球队队长。
     We made him our monitor. 我们选他当班长。
     二、“make＋宾语＋adj.” 意为 “使某人 / 某事(变得)……”。如：
     The news that our team had won made us very happy. 我们队赢了的消息使我们大家非常高兴。
     We must make the rivers clean. 我们必须净化河水。
     友情提示：当宾语是不定式短语或从句时，多用it作形式宾语。如：
     I made it a condition that everybody must be on time. 我提出一个条件，人人都要准时。
     The heavy rain made it impossible for us to go out. 大雨使得我们无法出去。
     三、“make＋宾语＋do sth.（不带to的不定式）”意为 “使某人做某事”。如:
     What makes the grass grow? 什么东西使得草生长？
     Our teacher makes us feel more confident. 老师使得我们感到更自信了。
     友情提示：在被动语态中，此类结构中省略的动词不定式 to 要还原。如：
     The boy was made to work twelve hours a day. 这个男孩被迫每天干十二个小时的活。
     Every day I am made to have an egg and some milk. 我每天不得不吃一个鸡蛋，喝一些牛奶。
     相关链接：have, make, let等使役动词和see, hear, listen to, look at, watch, notice, observe 等感官动词都可接不带to的不定式作宾补。help后可带to,也可不带to。如：
     Let him do whatever he wishes to do. 他想干什么就让他干吧。
     Did you see him go out? 你看见他出去了吗？
     I often help my mother (to) do some housework. 我经常帮助妈妈做些家务。
     四、“make＋宾语＋Ｖ-ed（过去分词作宾补）”这个结构指宾语接受后面的那个动作，表示被动的意思，意为 “使某人 / 某事被……”。如：
     The strange noise made us frightened. 奇怪的声音使我们感到恐惧。
     The good news made us excited. 这个好消息使我们兴奋。
     友情提示：通常情况下，make后的宾语是反身代词时，作宾补的动词要用过去分词，即：make oneself＋V-ed （heard, known, understood）。如：
     He couldn't make himself heard above the noise of the traffic. 在交通嘈杂声中他无法使自己的声音提高到让别人听到。

4.She says the new technology has not changed existing language but has greatly added to the vocabulary.

add to增加,增添,补充

例句：Hops also contain tannins, which add to beer color.
       它还含有能增进啤酒色泽的单宁。
