My name is George．I'm from England．Now I'm studying in Germany．I get to school at 7：30 every morning．I find many of my schoolmates come to school by bike．  ①   

    This is an interesting thing for me．In England people usually drive，take a bus or walk somewhere，for example，to school．In Germany, I often see people，even people over eighty years old going somewhere by bike．It makes me think：  ②   

My father gives the answer．We are living in Northern Germany．It is very flat(平坦的).So it is easy for people here to go somewhere quickly by bike .And it's cheaper than(比…….便宜)going by car or by bus．Also,it's good for the environment(环境)．

    I like riding bikes now．   ③    When I go back to England，I will ride more and ask my friends to ride with me．I think they will like tiding bikes，too．

{#blank#}1{#/blank#}Welcome to our talk show, Mr Brown. You are an actor and busy every day. But you try to find much time to exercise. Could you tell us what you usually do in your free time?

{#blank#}2{#/blank#}I know you like skateboarding, little John. When did you start it? How often do you go skateboarding?

{#blank#}3{#/blank#}I know you don't need to go to work on weekends, sir. How do you usually spend your weekends?

{#blank#}4{#/blank#}Fruit, vegetables and milk are good for us. They are healthy. Do you often have them, Miss Yang?

{#blank#}5{#/blank#}As a waiter, you work at night and sleep in the day. How many hours do you sleep every day, Mr. Green? Do you think it's the same as a day job?

A. I'm busy and tired on weekdays. So I want to relax myself at home on weekends. I like surfing the Internet and do it for five or six hours every Saturday and Sunday.

B. I cook at home from Monday to Friday. On weekends, I usually go out to have dinner with my husband and son. Maybe I must find a job next month.

C. Skateboarding is fun. I started to learn to skateboard when I was five years old. Now I go skateboarding four or five times a week.

D. They are really good for us. I eat lots of fruit and vegetables every day. But I hardly drink milk. I think only kids can drink lots of milk.

E. I'm really busy. I have lots of movies and TV plays to make. But I want to keep in good health. So I do some running in my free time.

F. Most of us work and have meals in the day and sleep at night. A night job is different from a day job. I usually sleep for six or seven hours in the day. But I can't have meals like people who work in the day.

    Once upon a time, a cat and a mouse were good friends. They lived a happy life in the same house. One day they went to the market and bought a big piece of cheese. They put it under a tree for winter.

    A few days later, the mouse wanted to eat the cheese. He told the cat that he had to join a baby's birthday party and then left. The mouse ate half of the cheese and returned home. When the cat asked him what the baby's name was, the mouse said" Half­gone".

    After a few days, the mouse wanted to eat some cheese again. He told the cat he had to join another baby's birthday party. He finished the other half and told the cat the baby was called "All­gone".

    When winter came, the cat went to the tree to get the cheese. But he found nothing. From then on, mice and cats were not friends any more.

    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.

Mary: Hey, Alexis, I am glad you came over to my house to study for our coming Math exam. {#blank#}1{#/blank#} I have gone over all my notes, but I am still not confident enough.

Alexis: Yes, this test is going to be hard. {#blank#}2{#/blank#} But I haven't had time to study the notes yet. Let's do a review together, starting from Chapter One (第一章). OK?

Mary: {#blank#}3{#/blank#} Let's do it!

Alexis: Well, do you remember what content (内容) was covered in the first chapter?

Mary: Yes, I think I do. The first chapter is about the quadratic function (二次函数). Is that right?

Alexis: Yes! You got it! Good job! {#blank#}4{#/blank#} Can you finish it in five minutes?

Mary: I don't know, Alexis! I am not good at writing quickly. I always have difficulties putting my thoughts on paper. I've worked hard to improve my math skills, but I still have a long way to go.

Alexis: I do not think that is your problem. {#blank#}5{#/blank#} Things can get worse when you start to feel nervous.

Mary: Thanks for your advice. When we are done with this, I will test you on Chapter Two.

Alexis: Okay!
