Critical thinking means thinking logically and developing an ability to ask questions or ask for evidence for a particular subject. Developing critical thinking skills in a child through the right critical thinking exercises is very important.
Critical thinking develops the ability of subjective analysis of a particular fact. Critical thinking is to evaluate the reason behind a particular fact. All possible viewpoints must be thought about before analyzing a fact, and this develops problem-solving skills in a child.
Here are some exercises you can use to encourage your child to think critically.
Quiz your child. Ask your child about daily activities that he does in the school. Quiz him about certain things that do not have a single correct answer. This will increase his ability to think about the things he’s just learned in class. Keep on telling your child simple information about nature, like the seasons when flowers bloom. You can either ask him questions or just explain to him in a casual way.
Recognize and classify. For critical thinking, your child must learn to recognize important information that is closely connected with the subject. Classification of things on a certain firm and logical basis of information is included in the critical thinking ability. Colorful toys or images can be included in teaching critical thinking. Ask your child to identify the names of the flowers, fruits and animals from a colorful chart.
Critical thinking exercises are not intended to make your child intelligent, but it is about making him successful in his decision-making ability and helping him make a successful career. Although thinking habits are cultivated(培养) in early childhood through exercises, they are indeed helpful for a lifetime.
Title: Critical Thinking Exercises for Children

Ostriches(鸵鸟) have been said to be so stupid that they react to danger by burying their heads in sand. This belief caused the popular phrases to be born: play the ostrich. It’s often used to describe people ________ refuse to face painful facts. They prefer to ignore the truth. It is like children sticking their fingers in the ears ________ crying, “I can’t hear you!”
But do ostriches really bury their heads in sand when they are in danger? The answer is no for sure! _______ ostriches are flightless(不会飞的) birds, they can run as fast as 40 miles per hour. So, if they find _______ in danger, they will run very fast.
It’s a false statement we’ve thought of as ________ truth for long. So, how did the phrase “play the ostrich” come from? Well,______ fact, ostriches swallow sand and pebbles(鹅卵石) to help grind(磨碎) food in their stomachs. This means they have to bend _______ and put their heads into sand to collect pebbles. That’s _______ a false statement was born

One of the most well-known directors of our time is Stephen Spielberg. He was born in Cincinnati on 18 December 1946. His father was an electric engineer and his mother was a performing pianist. His sister, Anne Spielberg, became a screenwriter who wrote the stories for many famous films.
Stephen had always wanted to be a director ever since he was a young boy. When he was just 13 years old, he made a 40-minute film. It won a local competition. Three years later, he produced a film called Firelight, which made one hundred dollars’ profit at the cinema in his hometown. Many of the ideas from this film were later used for one of his most famous films called Close Encounters of the Third Kind.
When he was 18 years old, he wanted to go to film school so that he could improve his skills and become an even better director. Unluckily, he was unsuccessful in getting a place at this school so he went to a university in California to study English. Even though he had failed to get into the school he wanted to go to, he didn’t let this stop him following his dream to become a great director.
Stephen Spielberg has directed many films since his first major film in 1976. He now owns many different businesses, most of which are involved in the film industry.

For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料电池).
But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.
The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(铂). The membrane separates the electrons(电子) from the protons(质子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.
Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.

Should doctors ever lie to benefit their patients to speed recovery or to cover the coming of death? In medicine as in law, government, and other lines of work, the requirements of honesty often seem dwarfed by greater needs; the need to protect patients from brutal news, to uphold a promise of secrecy or to advance the public interest.
What should doctors say, for example, to a 46-year-old man coming in for a routine physical checkup just before going on vacation with his family who, though he feels in perfect health, is found to have a form of cancer that will cause him to die within six months? Is it best to tell him the truth? If he asks, should doctors reject that he is ill, or minimize the gravity of the illness? Should they at least hide the truth until after the family vacation?
Doctors face such choices often. At times, they see important reasons to lie for the patients’ own sake; in their eyes, such lies differ sharply from self-serving ones.
Studies show that most doctors sincerely believe that the seriously ill patients do not want to know the truth about their condition, and that informing them of risks destroys their hope, so that they may recover more slowly, or deteriorate faster, perhaps even commit suicide.
But other studies show that, contrary to the belief of many physicians, a great majority of patients do want to be told the truth, even about serious illness, and feel cheated when they learn that they have been misled. We are also learning that truthful information, humanely conveyed, helps patients cope with illness; help them tolerate pain better with less medicine, and even recover faster after surgery.
There is an urgent need to debate this issue openly. Not only in medicine, but in other professions as well, practitioners may find themselves repeatedly in difficulty where serious consequences seem avoidable only through deception. Yet the public has every reason to know the professional deception, for such practices are peculiarly likely to become deeply rooted, to spread, and to trust. Neither in medicine, nor in law, government, or the social sciences can there be comfort in the old saying, “What you don’t know can’t hurt you.”
