Counting the number of miles traveled done by a product is a strange way of trying to tell the true situation of the environmental damage due to industry. Most food is transported around the world on container ships that are extremely energy efficient. It should be noticed that a ton of butter transported 25 miles in a truck to a farmers' market doesn't necessarily use less fuel on its journey than a similar product transported hundreds of miles by sea. Besides, the idea of “food miles” ignores the amount of fuel used in the production. It is possible to cut down your food miles by buying tomatoes grown in Britain rather than those grown in Ghana. The difference is that the British ones will have been raised in heated greenhouse and the Ghanaian ones in the open sun.

    What is the idea of “food miles” doesprovide, however, is the chance to cut out Third World countries from First World food markets. The number of miles traveled by our food should, as I see it, be regarded as a sign of the success of the global trade system, not a sign of damage to the environment.

    Researchers from France and Italy discovered that Canadian parents are less strict with their children than mothers and fathers in France and Italy.

    “Our most important finding was the difference between Canadians and the others,” said Professor Michel Claes, the lead author of the study. “Canadians focus on independence and negotiation. On the other hand, Italians, for example, exercise more control. We found Canadians seem to focus on negotiation in case of a conflict.”

    Claes said Canada, France and Italy were selected for the study because they share important cultural and social factors. “We chose French­Canadians because they share the same language as France, and originally came from France and share certain values. Italy was included because it was considered to have similar, strong and important family values,” he explained.

    The researchers examined the emotional ties between parents and their children by questioning 1,256 students aged 11 to 19 years old.

    Canadian students reported less control and more free actions, according to the study. Italian parents were stricter and French parents were somewhere in the middle.

    Claes explains that the differences lie in education in Canada, France and Italy.

    “North America has its own educational values, which promote individualization. Tolerance and comprehension are encouraged. Italy, on the other hand, promotes respect of authority, control, and the need for permission.” he said.

    Children from all three countries described their mothers as warm and communicative. Italian and Canadian children had similar feelings about their fathers, and reported high levels of emotional ties. But French fathers were generally thought by their children to be more distant and cold.

    “We were surprised by this,” Claes admitted.“It seems as though the relationships between French mothers and their children were becoming closer over time, while fathers maintain a form of distance and coldness, which is more of a source of conflict in France than in the other countries.”

    Nowadays wind is useful. Think about the different ways that people use the wind. You can use it to fly a kite or to sail a boat. Wind is one of our cleanest and richest power sources, as well as one of the oldest. Evidence shows that windmills began to be used in ancient Iran back in the seventh century BC. They were first introduced to Europe during the 1100s, when armies returned from the Middle East with knowledge of using wind power.

    For many centuries, people used windmills to grind wheat into flour or pump water from deep underground. When electricity was discovered in the late 1800s, people living in remote areas began to use them to produce electricity. This allowed them to have electric lights and radio. However, by the 1940s, when electricity was available to people in almost all areas of the United States, windmills were rarely used.

    During the 1970s, people started becoming concerned about the pollution that is created when coal and gas are burned to produce electricity. People also realized that the supply of coal and gas would not last forever. Then, wind was rediscovered, though it means higher costs. Today, there is a global movement to supply more and more of our electricity through the use of wind.

    Put an ice cube(小冰块) from your fridge into a glass of water. You have a piece of string(线) 10 centimeters long. The problem is to take out that piece of ice with the help of the string. But you must not touch the ice with your fingers (手指).

    You may ask your friends to try to do that when you are having dinner together. There is a saltcellar on the table. You must use salt when you carry out this experiment.

    First you put the string across the piece of ice. Then put some salt on the ice. Salt makes ice melt(融化). The ice round the string will begin to melt. But when it melts, it will lose heat. The cold ice cube will make the salt water freeze(冻结) again.

    After a minute or two you may raise(提起) the piece of string and with it you will raise your piece of ice!

    This experiment can be very useful to you. If, for example, there is ice near the door of your house, you must use very much salt to melt all the ice. If you don't put enough salt, the water will freeze again.

It was the Dragon Boat Festival. Shiny white tents lined the waterfront, {#blank#}1{#/blank#} (provide) shade and refreshments for dragon boat paddlers (桨手) from all over California, {#blank#}2{#/blank#} gathered around the Castaic Lake for a festive competition.

Giggling kids raced cheerfully along the lakeside beach, with  {#blank#}3{#/blank#} (they) parents enjoying the shady picnic areas under the trees along the shore. "It's a great day out," said Paul Lin, co-founder of Castaic's own Dragon Eyes team.

Dragon boat racing has been going on for thousands of years in China, {#blank#}4{#/blank#}  (initial) conducted in honor of the poet Qu Yuan, as a way  {#blank#}5{#/blank#} (honor) his legacy and spirit.

In the race, a drummer  {#blank#}6{#/blank#} (use) a large traditional wooden drum to keep the paddlers on the beat, {#blank#}7{#/blank#}  a steersman in the back keeps them in their lane.

Lin said a friend got him  {#blank#}8{#/blank#} (involve) in dragon boat racing over a decade ago. In 2018, they decided to host their own festival. "There's something really special to be learned from our dragon boat motto: One Boat, One Beat," he said. "Paddlers come from all walks of life and that kind of {#blank#}9{#/blank#} (close) with people is nowhere else to be seen."

"We really want to help expand people's awareness and grow the sport," said Lin. "We're hoping one day it will become  {#blank#}10{#/blank#}  Olympic sport."
