Dear Dad and Mom，

    Thanks a lot for your great love for me.

Most people around the world are right-handed. This also seems to be true in history. In 1799, scientists studied works of art made at different times from 1,500 B.C. to the 1950s. Most of the people shown in these works are right-handed, so the scientists guessed that right-handedness has always been common through history. Today, only about 10% to 15% of the world's population is left-handed.

Why are there more right-handed people than left-handed ones? Scientists now know that a person's two hands each have their own jobs. For most people, the left hand is used to find things or hold things. The right hand is used to work with things. This is because of the different work of the two sides of the brain. The right side of the brain, which makes a person's hands and eyes work together, controls the left hand. The left side of the brain, which controls the right hand, is the centre for thinking and doing problems. These findings show that more artists should be left-handed, and studies have found that left-handedness is twice as common among artists as among people in other jobs.

No one really knows what makes a person become right-handed instead of left-handed. Scientists have found that almost 40% of the people become left-handed because their main brain is damaged when they are born. However, this doesn't happen to everyone, so scientists guess there must be another reason why people become left-handed. One idea is that people usually get right-handed from their parents. If a person does not receive the gene (基因) for right-handedness, he / she may become either right-handed or left-handed according to the chance and the people they work or live with.

Though right-handedness is more common than left-handedness, people no longer think left-handed people are strange or unusual. A long time ago, left-handed children were made to use their right hands like other children, but today they don't have to.

Alice is our new foreign teacher. She has changed a lot in the past five years. 

My hometown Nanjing is in the eastern part of China.As the capital of Jiangsu，it is a modern and busy city.And it is one of the cities with the longest history in China.With the development of the economy（经济），it has changed a lot in the past few years.

For one thing, people took tramcars (有轨电车) to go out in the past. But now many people choose to take a subway because of its convenience (便捷). What's more, taking a taxi becomes very popular. It has an app on the phone, and some people use it to call a taxi. It may be much cheaper.

Besides，the building is different from the past.In the past，the tallest building in Nanjing was Jinling Hotel.It had 37 floors.At that time，the tallest building is Zifeng Tower.It has 78 floors.Different from the past，you can see tall buildings everywhere in Nanjing.

As for the environment，in the 1980s and before，Nanjing was full of trees，people paid little attention to the importance of plants and fresh air.Plants were cut down and the air got worse. Now, to improve the living place, people take all actions to grow plants and cut down pollution. The environment is getting better now.

The Best Way to Travel

I did a survey about the best way to travel in my class. Here are the results. 

Thirty- five percent of my classmates like {#blank#}1{#/blank#}(travel) by plane. They choose to take the plane {#blank#}2{#/blank#} it's the fastest way. {#blank#}3{#/blank#}, it's also the most expensive. Forty- five percent of them think the train is their first {#blank#}4{#/blank#} (choose). It's{#blank#}5{#/blank#}(safe) and the most comfortable. Besides, it's the second {#blank#}6{#/blank#}(fast). It usually costs less {#blank#}7{#/blank#} taking the plane. Only twenty percent of them choose the coach {#blank#}8{#/blank#} their best way to travel. It's the cheapest but also {#blank#}9{#/blank#}(slow) way. 

Whatever you choose, safety is always {#blank#}10{#/blank#} (important) thing of all. Do remember that!

A new AI system can be used to make predictions(预测) on the crop yields(产量) up to six months before harvest. The tool counts flowers on fruit trees, which can help farmers improve crop yields and make better use of water and labor, and to plan harvests.

The system, developed by researchers at the National Robotarium in Edinburgh, can count flowers on fruit trees from photos taken by a smartphone. It works by knowing features, such as the edges and shapes of flowers. In Spain, studies on peach trees showed the system to be 90% correct in flower counts, which is much better than the 30% to 50% mistakes made by humans, according to researchers.

 "In countries all across the world, farmers often depend on traditional methods to predict their yields, which can lead to big mistakes, " said Fernando Auat Cheein, a professor at the National Robotarium. "The flower-counting AI makes it possible to help farmers make wise decisions about crop management. "

"By paying more attention to the areas of the farm that are expected to produce the most fruit, farmers can make the most of resources(资源), reduce their environmental effect, and improve the harvest, " said Mr Cheein. "Our AI tool can be used with traditional farming practices, making it easier for growers to get help without completely changing their present methods. " The researchers will next compare the AI's predictions with the actual peach harvest in the following months. If these turn out to be effective (有效的), they believe the method could be used for crops such as apples, pears, and cherries, helping fruit growers in Britain, Europe, and other areas.
