Tone of voice is very important in human conversation. A person might use words that communicate one message and a tone that shows something very different. This possibility for confusion is one reason that businessmen encourage discussing things in person, rather than through email, as tone cannot be determined in the written form.

    The same rule is true with children. Children as young as a few months respond to a change in voice. It has been recorded that babies prefer to hear a story read by their own mother rather than another woman whom they do not know.

    Have you ever talked to someone who had little or no changes in their voice no matter what you were discussing? Think of the teacher or professor you had in the past that spoke in a monotone manner for the entirelecture. It is very boring and difficult to become interested in the topic.

    Parents should make an active effort to communicate with your child. If your child figures out how to open a box he or she has been struggling with and says “YES!” with pride in his or her voice, your response should be happy and excited (something encouraging, like “You did it!”). If you plainly said the same thing, you would not be matching the tone of your child.

    This applies to feelings that the child may express in everyday situations as well. If a child argues with a friend, your response should not be said in a high voice or with a smile. Seriously and sincerely you should say “You look sad” or “That must have been hard for you”.

    The tone of your voice expresses understanding, acknowledgement, connection and several other healthy things to your child. Although your words are very important, equally important is the tone with which you say those words.

    You've probably visited the Tian'anmen Gatetower—the landmark building of Beijing, but you may not have heard of Kuai Xiang. Along with him, the following remarkable architects all took the center stage at their times.

    Kuai Xiang(1399—1481)

    Tian'anmen Gatetower is universally considered the brainchild of Kuai Xiang. By following in the footsteps of ancient homebuilders, he successfully presented the Emperor Judy with a grand wooden structure which has stood the test of time for almost 600 years. Visitors are also hooked on its delicate paintings.

    Ieob Ming Pei (1917-present)

    His motto is: Traditions should be sealed in glass boxes at museums. He is always struggling with innovation. Although under grilling from French conservative critics, he still planted a glass pyramid into the courtyard of the Louvre. His other works include John F. Kennedy Library, Beijing Fragrant Hill Hotel and Suzhou Museum.

    Zaha Hadid(1950-2016)

    In 2004, she became the first woman to win the Pritzker Architecture Prize, the Nobel Prize for architecture. She used tricks to maximize available space. Her fluid-style works pioneer the concept of micro-living. The curves(曲线) of Guangzhou Opera House perfectly match the rise and fall of its surrounding buildings, forming a unique view.

    Meng Fanchao (1959-present)

    Many people dismissed the building of a mega bridge as a pipe dream, but Meng Fanchao turned this into reality by building Hong Kong-Zhuhai-Macao Bridge. This longest cross-sea bridge, when viewed afar, looks like a dynamic dragon braving the rolling waves of Lingding Sea.

    Smoking is harmful. But as soon as you quit the habit, everything will be OK, right? Wrong.

    New research has found that even if you give up smoking, the damage it has done to your genes will stay there for a much longer time. In the research, a team of US scientists studied the blood of 16,000 people. Among them, some were smokers, some used to smoke, and the rest were non-smokers. Scientists compared their genes and found that more than 7,000 genes of smokers had changed--a number that is one-third of known human genes.

    According to NBC News, both heart disease and cancer are caused by genetic changes. Some people may have had the changes when they were born, but most people get them in their day-to-day lives while doing things like smoking.

    When you stop smoking, a lot of these genes will return to normal within five years.

This means your body is trying to heal (治愈) itself of the harmful effects of smoking. But the changes in some of the genes stay for longer. They can stay for as long as 30 years, It's almost like leaving a footprint on wet cement (水泥)—-it will always be there, even when you've walked away and when the cement becomes dry.

    Although the study results may make people unhappy, there is a bright side: the findings could help scientists invent medicine to treat genetic damage caused by smoking or find ways to tell which people have heart disease or cancer risks.

    Police Officer Tidwell left the station just after 8 a.m. on Sunday June 4. He had spent a boring night on duty and was looking forward to his day of rest. By habit he took a short-cut down the path behind Dugby Hall road and after a minute or two he saw a man climbing down a drainpipe (雨水管)from an open bedroom window of Number 29. In silence, Tidwell crept into the garden. The man reached the ground and was dusting himself down when he felt his arm caught.

    "It's 8:15 on a Sunday morning," said the officer, "and this sort of thing seems an unlikely adventure at such a time. Would you mind explaining?"

The man was obviously scared but tried to keep calm. He said, "I know what you are thinking, officer, but it isn't true. This is a funny mistake."

    "It's part of my job to take an interest in unusual events. I think you've just left this house in a manner other than the customary one. That may be quite innocent, but I'd like to make sure." Tidwell took out his notebook and a pen. "Name, address and occupation and then, please, tell me your story..."

    "Charlie Crane, lorry driver, from Nottingham, 51 Breton Street. My story..."

    "Yes. What were you doing like a fly on that wall, Mr. Crane?"

    "Well, I had a breakdown yesterday and had to stay the night here. Bed and breakfast. The land-lady's name is Mrs. Fern. She gave me breakfast at seven, and I was out of he: mthe right way and down at the lorry by half past seven. Only when I felt around for a cigarette did I realize I'd left $80 in my envelope under the pillow here at number 29. I always put it under my pillow at night. It's a habit I've got into. I even do it at home...

    "I see. Why didn't you miss it when you went to pay Mrs.... What's her name?"

    "I'd paid her last night. You've got to pay when you take the room, see? So I came rushing back, but it's Sunday, and she'd gone back to bed, and could I wake her? I rang the bell and banged on the front door for ten minutes before I came round here to the back and spotted my bedroom window still open. Up I went, then, up this pipe. It's a trick I learned in the army. She didn't make the bed、and money was still there. You know the rest, I hope you believe it because... "

    "Mr. Crane, whatever are you doing here? I thought you'd gone an hour ago." It was Mrs.  Fem, speaking from the kitchen at the corner of the house.

Everything to know about Singapore

Here is how to plan the best possible trip to this impressive city-state.

When to go

Positioned just one degree north of the Equator, Singapore is consistently tropical. So it's more a matter of when not to go. Namely: the monsoon season between November and January when the city is blanketed in regular rainfall.

What to celebrate

Singapore celebrates its independence in an annual celebration known as National Day. Every year on August 9, the holiday is marked with great excitement that extends into the evening, ending in a massive fireworks display over Marina Bay.

What to eat

Hainanese chicken rice is considered the national dish of Singapore, as you can find it just about everywhere. If you are looking for something a bit spicier, try laksa--a coconut curry-based noodle soup.

Souvenir to take home

The Merlion is Singapore's official mascot(吉祥物), a mythical beast with the head of a lion and the body of a fish. Many local salesmen offer hand-carved figurines that fit easily into carry-on luggage and will serve as a lasting symbol of your time here. Anyone who's ever visited this place directly connects the symbol to the city.

Travel trip

Hawker centers are open-air food markets featuring delightful street food. Eat at these as much as possible to support local business and for a true taste of Singaporean dining customs. While each has its own charm, Maxwell Road Hawker Center in Chinatown is the most famous.

Instagram-worthy view

A photo from the world's largest rooftop infinity pool-- connecting the three towers of the Marina Bay Sands-- is a must for many tourists here. But back on the ground, Merlion Park affords a more impressive view of the hotel itself.
