An English Corner

<正>On Friday afternoon,Mr.Zhang told us that there would be an English corner in front of our teaching building.I went there soon after class in the afternoon.To my joy,the English corner had just been on for a few minutes.I joined them in their talk.At first,I was afraid that my English was so poor that I couldn’t follow them     

A Busy Weekend

<正>I had a busy weekend.On Saturday morning,I got up before 7 o’clock,and washed my hands and face quickly.Then I had to do some cleaning in the house.At about 11 o’clock,cooked lunch for my family in the kitchen.In the afternoon,I did my homework.English was     

A Wonderful Party

<正>My name is Chen Siwei. I’m from Class 4, Grade 8 of No. 4 Middle School. Last Friday afternoon, we had a class party. At the party, we invited our English teacher, Mr. Zhang, to give us a talk on how to learn English well. Because of being good at singing, my deskmate Lin Tao sang the English song WE WISH YOU A MERRY CHRISTMAS. Zhou Hao and Shen Wei     

Money Returned to the Owner

<正>Yesterday afternoon,I went home by bike after school.When I passed the hospital,I sawa handbag lying on the ground,so I picked up it(1).Out of great wonder,I opened it and found there were(2)$800 and a mobile phone in it.I

Wind-tunnel investigation of point pressure on TTU test building

External point pressures at mid-plane and roof corner locations, measured during a wind tunnel study of a 1: 50 geometrical scale model of the TTU test building, are reported in the paper. The mid-plane laboratory pressures are compared with field and numerical results. The agreement/discrepancy between the compared results is discussed. The roof corner pressures acquired for a wider than previously reported range of the wind azimuth are presented and compared with the available field results. Type I and III extreme value distributions (EVDs) are fitted to peak suctions acquired at four locations in a roof corner region. For the mid-plane locations, a very good agreement between the model and full-scale pressures is attributed to a close matching of the laboratory and field approach flows. The laboratory-field comparison of the roof corner pressures revealed trends observed in previously reported investigations. The extreme value analysis showed that the field peak pressures in this region were bounded by the laboratory peak pressures (the lower bound) and by the asymptotic limit of the type III EVD fit of the laboratory peaks (the upper bound). Rapid convergence and other attributes make type I EVD a fit of choice for the reported extreme wind pressures.     

My Hobbies

<正>I have many hobbies,such like1sports,singing,and reading books.In school,I often hear the P.E.teacher say that sports do good to our health,and willmake us live longer.So,I like sports very much.I begin running at six o’clock in the morn-ing.And after classes in the afternoon,I often play pingpong with my friends.Sports can keep     

Climb a Hill

<正>This Saturday,I am going to climb a hill with my classmates.What should I wear?I am thinking about it.I can wear my jeans and trainers because they are fit for climbing a hill.It will be hot in the afternoon that day,so I want to wear a silk shirt.And it will be cool in the morning,so I am going to take my jacket with me.It can make me feel warm.I will enjoy myself in the mountain.     

A Special Summer Holiday

<正>This year’s summer holiday was the most unforgettable.I spent fifteen days at my grandparents’home in the countryside.Every morning,I went to the field to help my grandparents do farm work after have1breakfast.I learned a lot of agricultural knowledge from them.In the afternoon,I usually spent most of my time on the hill.My new friends and I ran after each other,picked fresh fruits and catch2butterflies together.There was always so many3fun.
