The Structure for Emphasis (2) 强调结构(2)
The Auxiliary Verb Do (助动词Do)
英语中常用的强调结构是“It is (was) + 被强调部分(主语、宾语或状语) +that (who)…”一般来说，被强调部分指人时，可用who代替that; that是万能的，既可指人又可指物。

那么怎样强调谓语呢?
助动词do被用来加强语气时，基本结构为：do+动词原形；第三人称单数一般现在时为：does+动词原形；一般过去时为：did+动词原形。

He does know the place well (does+动词原形)
他的确很熟悉这个地方。

(A)
As a result of po1lution，Lake Erie，on the borders of the USA and Canada，is now without any living things.
Pollution in water is not simply a matter of “poisons”killing large numbers of fish overnight. Very often the effects
of pollution are not noticed for many months or years because the first organisms (生物体) to be affected are either plants
or plankton (浮游生物). But these organisms are the food of fish and birds and other creatures．When this food
disappears, the fish and birds die too. In this way a whole food chain Can be wiped out，and it's not unti1 dead fish and
water birds are seen at the river's edge or on the seashore that people realize what is happening.
Where do the substances which pollute the water come from? There are two main sources of sewage (污水) and
industrial waste. As more detergent (洗涤剂) is used in the home，so more of it is finally put into our rivers，lakes and
seas. Detergents harm water birds, dissolving the natural substances which keep their feathers
water-proof. Sewage itself，if not properly treated，makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen
they need．Industrial waste is even more harmful as there are many highly poisonous things in it，such as copper and
lead(铅).
So, if we want to stop this pollution，the answer is simple：sewage and industrial waste must be made clear before
flowing into the water. It may already be too late to save some rivers and lakes, but others can still he saved if the correct
action is taken at once.

in the other person's shoes.
For anything you're about to send：ask yourself, “Would I say this to the person's face?”If the answer is no, rewrite and
reread. Repeat the process tie you feel sure that you'd feel comfortable saying the words to the person's face．
If someone in the chat room is rude to you，your instinct is to fire back in the same manner. But try not to do so. You
should either ignore the person, or use your chat software to block their messages If it was caused by a disagreement with
another member，try to fix the situation by politely discussing it．Remember to respect the beliefs and opinions of others
in the chat room.
Everyone was new to the network once. Offer advice when asked by newcomers，as they may not be sure what to do or
how to communicate．when someone makes a mistake whether it's a stupid question or unnecessarily long answer be kind
about it. If it's a small mistake，you may not need to say anything .Even if you feel strongly about it，think twice before
saying anything Having good manners yourself doesn't give you license to correct everyone else．If you do decide to tell someone about a mistake，point it out politely．At the same time，if you find you are wrong，be sure to correct yourself and apologize to those that you have offended It is not polite to ask others personal questions such as their age，sex，and marital status．Unless you know the person
