Have you ever had the feeling that no one can understand you? Well, here comes “Pepper”, it could be about to change all that. Pepper is the first robot to read human feelings. Using its emotion recognition functions(情感识别功能), Pepper can make jokes, dance and even sing to people when they are around it.

 The robot looks like a lovely girl. It is four feet tall with a tablet computer in its chest. It has human-like hands, a girl-like body and baby-like voice. It was shown to attract people at stores on Friday.

Pepper can tell facial expressions, human voice and signs, then make an answer. Pepper is designed to be a family robot, but it isn't like the household robot on the cartoon. Pepper is used at home or store, where we enjoy pleasure and entertainment.

 At home, not only can it tell jokes, it also helps people in trouble. If a natural accident happens, it can encourage them, make them laugh and feel relaxed.

 Pepper will be on sale at the price of $2,000 in August, 2015. At present, several Peppers are on show at stores for people to visit. Before selling Peppers, the creators want them to store more knowledge in order to get better along with human beings.

    Mr and Mrs Smith have two sons and two daughters. They're Tom,Jack,Sally and Mary. They're quadruplets(四胞胎), so their birthday is on the same day—July 22nd.

    It's their fourteenth birthday today. Their parents buy some things for them:four cakes, two T-shirts and two skirts. The four cakes are the same, and one cake is 15 dollars. The two T-shirts are the same,too. They are yellow and 35 dollars for one. The price of the two skirts is the same and one skirt is 60 dollars. But their colors are not the same. Sally likes blue and Mary likes green, so the blue skirt is for Sally and the green one is for Mary.

    Last Friday night I went to a great party. It was a birthday party for my English teacher Mrs Brown. Students in my class all went to celebrate(庆祝) her 40^th birthday. We began to prepare for(为……做准备) the party two weeks before that, but Mrs. Brown didn't know anything about it.

    We all met at a restaurant at a quarter to seven. There were about 30 people. Mrs. Brown's son took her to the restaurant and they arrived at seven o'clock. Just before seven, we all stayed in one room of the restaurant and it was dark in the room.

    When they got to the restaurant, Mrs. Brown's son asked her to go into the room first. Then we all shouted, "Surprise!"

    Mrs. Brown was really surprised. She jumped when she heard us. Then we sang "Happy Birthday to You" and she knew what was happening(发生). We all had a great dinner and then a delicious birthday cake.

    For her birthday, Mrs. Brown got a beautiful quilt. We all printed(印) our photos on it. So it was a very special quilt.

    Mrs. Brown enjoyed the party, and we enjoyed it, too.

    One weekend, a wife and a husband(丈夫)went to visit a shop in Tokyo. After they got back home, they couldn't find their camera(照相机). They thought the camera must be in the shop. After a few weeks, they went to that shop again and the boss of the shop gave their camera back to them.

    When their pictures of the camera came out, the husband saw two pictures he did not take. One is a man standing at the door of the shop. In his hand there is a piece of paper(纸) with some words on it "I find your camera. "The other is a boy with a piece of paper in his hand. There are some words on the paper too "I take the pictures".

    When it comes to the letter grade on your test or homework, you might notice that there is no letter E. Have you ever thought about why that is so?

    In the A. B. C. D and F grading system, the first four letter are typically considered passing grades. An F in this system simply stands for "fail". The word "fail" happens to start with the letter F, which seems to leave out the letter E, The fact of the matter is that any letter can mean "not-passing" or "fail". Some schools have U grade for unsatisfactory", or I grade for "incomplete."

    Even with all this said, we should also point out that E grade actually has been used pretty commonly throughout the history of letter grades in the US.

    The first college in the US to use a letter grading system like the ones we use today is Mount Holyoke College. In 1897, they began to use the following grading scale:

A: 95-100% (excellent)   B: 85-94%(good)   C: 76-84%(fair)

D: 75%(barely passed)   E: below 75%(failed)

    We can see the inclusion of E instead of F.

    Gradually, the letter grading system became more popular throughout the US. However, many schools decided to drop the E grade and go straight to F. There is no evidence(证据)to really support this, but one possible explanation is that teachers were worried that some students and parents might mistake E for "excellent".

    Why do we have letter grades? Well, part of the reason is that they made grading simpler during n time of great change for schools. As the 20th century began, growing cites and an increase in immigration led to larger school classrooms. Most teachers at that time thought this new letter grading system was an easy, fair and clear way to grade students.

    Today, more and more people argue that letter grades don' t fully reflect(反映)student learning. However, as teachers try to improve grading methods, many parents continue to favor the letter grades they got as kids. They are familiar(熟悉) and easy for parents to understand. So while they might not be perfect, the letter grades probably aren't going away any time soon.

    Last week Lu visited England. He stayed with my grandmother. He said it was a strange visit. "I don't understand, but I frightened(害怕) your grandmother a lot. When I arrived, I gave her a purse from Zhengzhou, she looked in it and asked me to take it back.{#blank#}1{#/blank#}Do English people like spiders?"

    "Later we went shopping. Someone was painting a shop front, so there was a ladder(梯子).Grandmother stopped me from walking under it and said I must walk around it. I liked the shops and bought some lovely rose soap(肥皂) for my mother, a smart umbrella for my father and some new shoes for myself.{#blank#}2{#/blank#} Your grandmother came in and screamed(尖叫) !"

    "Then I broke a small mirror in the bathroom.{#blank#}3{#/blank#}I felt very sorry. When I left I gave your grandmother some flowers. She counted and there were 13. She didn't like it.{#blank#}4{#/blank#}"I explained to Lu, "My grandmother follows the old customs(习俗). You must not give someone an empty purse or they will have no money. You must not kill a money spider or the same will happen. Also it is very unlucky to walk under a ladder and to put new shoes on the table. An open umbrella in a house means someone will die. Breaking a mirror brings seven years' bad luck, and 13 is also a very unlucky number.{#blank#}5{#/blank#}."
