How to teach a child to respect

As a child grows out of being an infant and begins to notice and react to the world around him, you may find yourself wondering how you possibly impart (傳授) all of the things that he needs to become a responsible, respectful adult. 1. A child who learns to respect all he meets not only receives respect from others, but also learns to respect himself as well. Here are some instructions.

Show your child respect. This is perhaps the best way to teach your child how to respect others. Listen to your child by giving him your full attention and he will learn to listen to you, understanding how important this is in communication.

2. The more you say “please” and “thank you” to your child, the more likely he will learn to use them with you and others. Politeness then becomes a normal part of any conversation.

Agree to disagree. 3. Explain your decision so that he will understand your reasoning and expect respectful responses. Disagreeing with you doesn’t equate to disobedience (違抗).

Control your impulse (沖動) to overact. When a situation arises between you and your child

that requires calmness, keep in mind that you are supposed to be modeling correct behaviour. 4.___

Praise, praise, praise! So much is focused on what a child does wrong and how to correct it that the accomplishments are not celebrated enough. 5.___

A. Teach manners by using polite requests and responses.

B. Try to remember that a child won’t always agree with you.

C. Respect is necessary for a meaningful and successful life.

D. If he sees you lose your temper, he is more likely to respond that way in future.

E. A child may act like he pleases, but will respect being given limits.

F. When you see your child exhibit respectful behaviour, make sure he knows just how proud you are of him.

G. Setting a good example is the best way to start a child on the path to respect.

The 2016 Rio Olympic Games have come to an end. Without doubt, many Chinese sports fans sat in front of the TV and cheered our athletes on, hoping that they would get as many gold medals as possible.

But sometimes our desire for gold medals can result in the sadness of failure. When Liu Xiang, China’s track hero, pulled out of the Beijing Olympics due to injury, he greatly disappointed many Chinese sports fans.

But things are different now. In the 2016 Rio Olympic Games, we saw a healthier and more lenient Chinese attitude toward the sports people, fully in line with the Olympic spirit.

China didn’t win any gold medals on the first day. But, instead of criticizing the athletes who failed to finish on top of the podium(領獎臺), the majority of fans were happy with their efforts. “Reacting in the right way when an athlete misses out on gold shows the maturity of a person, and is also a challenge for a country to face up to in the process of development,” commented CRI.

Swimmer Fu Yuanhui won fans’ hearts, even if she only won a bronze medal in the 100m backstroke final. Her fans on her Sina Weibo micro blog have increased 100,000 to over 6 million. Many sports fans appreciated her straightforward character and attitude toward competition.

“The warm support from Internet users shows that public attitude toward competitive sport and the Olympics have gotten to a higher level,” said an article in the People’s Daily.

You're rushing to work and a man ahead of you falls down on the sidewalk. Do you stop to help? In a study of by-standers, it was found that some people keep on walking.

"There is a tendency to decide that no action is needed," says a psychologist, "In order to take action, you have to work against them." Here are some common thoughts that stop you from helping.

●Why should I be the one? I'm probably not the most able person in this crowd. You might think someone older or with more medical knowledge should offer assistance.

●What if he doesn't really need my help? The fear of embarrassment is powerful; no one wants to risk looking foolish in front of others.

●No one else looks concerned. We can follow the people around us, but most people tend to hold back their emotions in public.

"If you spot trouble and find yourself explaining inaction, force yourself to stop and evaluate the situation instead of walking on," says the psychologist. "Then retry to involve other people; you don't have to take on the entire responsibility of being helpful. Sometimes it's just a matter of turning to the person next to you and saying, 'It looks like we should do something.' Or asking someone if an ambulance has been called and, if not, to call for one. Once you take action, most people will follow you."

1.According to a study of by-standers, what will some people do when a man ahead falls down on the sidewalk?

A. They will call 110.

B. They will offer help.

C. They will go on walking.

D. They will laugh at him.

2. Which is NOT the common thought that stops you from helping others?

A. I'm not the very capable person.

B. It looks like we should do something.

C. No one else is concerned.

D. He doesn't really need my help.

3. In order to offer your timely help, you need to .

A. go directly to the police station

B. get along well with the passers-by who spot the trouble

C. ask others for help and call the police

D. work against the first thoughts that stop you from offering help

4.The main purpose of the passage is to tell readers .

A. to give others a hand

B. to be more able

C. to explain their inaction

D. to evaluate the situation

“We leave at dawn and head out overland by jeep towards Base One. We will get as far as we can before proceeding on foot,” Mark explained. The others sat and listened. Sarah, particularly, as a “casualty of events”, wouldn't have known what to say or suggest even if she’d been asked. But Harry had a lot to say.

“We'll never make it,” he protested(抗議). “We'll still be crossing the desert when they catch up with us. They’ll know where we’re heading for and they seem to know every move we make or are going to make.”

Mark said nothing, but spread his hands out as if to say “Well, what do we do then?” “We wouldn’t be in this mess now,” Harry went on, almost ignoring Mark’s gesture, “if we hadn't stopped to rescue Sarah.”( He glanced at her briefly.) “But since we did, we must get on—but not across the desert. There is the sand, and deep ravines (溝壑) which are almost invisible until you’re right on them and then the heat. You have to be used to going out there, and none of us is. This is no ‘morning at leisure’ on some pleasant holiday, you know! If we went north instead and made for the river,…"

He broke off and looked around at the others, feeling somehow that his argument was pointless. No one said anything.

“Good,” said Mark, look around with authority, and returned to checking their stores.

A beautiful sunrise was about to burst over the horizon as the jeep headed out towards Base One.

1.What can we know about the group of people?

2.What’s Mark’s plan?

A. To drive across the desert.

B. To make for the river on foot.

C. To drive as far as possible and then walk.

D. To leave before dawn and leave Sarah behind.

3.Why did Harry think that they should make for the river?

A. The journey would be more pleasant.

B. A river trip would be much safer.

C. The desert heat would kill them.

D. He knew the road leading north.

4.What can be inferred from the passage?

A. The group accepted Harry’s plan.

B. Mark was the leaders in the action.
