Description of an Interesting Person I Have Met It was early morning in Finland when I had just waked up. I was very tired, and I decided to go to the beach and just lie on the hot sand and sunbathe. When I creamed myself somebody bumped into me and that was him. He was chasing volleyball and after he had bumped into me he apologized and asked me to play volleyball with his friends and I agreed. He wore chequered shorts and his upper body was naked. He was very handsome, because he was
My best friend I have one best friend. Her name is Elen and we have known each other since we were 12 years old. We met with her in school in dance class about 14 years ago. If I were to describe how she looks, I would say she is very pretty. She has short brown hair, brown almond-shaped eyes, a small nose and a small pointed chin. She is not very tall but not short either and she is quite slim. She doesn't like to dress up so I usually see her wearing jeans and a T-shirt or sweater. It seems like she and I are always talking or laughing about something. She has a very nice
The Lord of the Rings SHORT SUMMARY Bilbo Baggins throws a party for himself and his protégé, Frodo. At the party, Bilbo announces that he is leaving his home to his heir, Frodo. He returns home and is met by his close friend, the wizard Gandalf. Gandalf insists that Bilbo remove the Ring that he has owned since the events of the previous adventure, chronicled in The Hobbit, and give the ring to his young heir. The Ring has special powers, the most obvious of which is to make the wearer invisible. Then Bilbo disappears. For many years Frodo lives in Bilbo's home at Bag End. Just like Bilbo, Frodo appears not to he aged. In his fifties, he grows restless. One day Gandalf comes to Frodo and

First impression of people are often wrong. Do you agree? We all live in diffrents places, we speak diffrent people and perceive around us new people everywhere we go. This new places and people may cause oftenly wrong impression when immediately we see someone new. Why is it so, why we do such conclusions, even tho we do not now person we just met. For example, in school, obviously we see who is popular and who is not. We see shy and confident persons. But after that we analyse that person and make ourself some knowledge about every person we see or met. Sometimes it is bad, sometimes it is not. What to talk about and what not, how do we act in their company and how we not should act. Some people you see them and know they have a bad time in their life. Some people you
pole siiani veel väga põhjalikult analüüsitud. Selles artiklis kirjeldatakse uuringut, mille eesmärk oli just uurida seos inimese südamerütmi ja välistemperatuuri vahelisi seoseid erinevate tegevuste vältel. Lisaks uuriti kas kehamassiindeks ja katsealuse sugu mõjutavad katsetulemusi. Tulemused näitasid, et südamerütmis oli märgatavat kiirenemist soojas keskonnas ja suurt füüsilist(metablic rate 2.5- edaspidi met 2.5) pingutust nõudvates tingimustes. Eriti meeste puhul kelle kehamassi indeks oli üle 22.0'i. Lisaks oli märgatav erinevus samades tingimustes 1.0 ja 0.8 Met'i korral. Sissejuhatus PMV(predictive mean vote model) mudel on populaarne kasutamaks inimeste reaktsiooni ja vastuvõtmist temperatuurile erinevates hoonetes. Süsteemi on üritatud aina parandada eesmärgiga tõsta inimese mugavust ja minimaliseerida energia kasutust vältides ülekütmist.

on the window sill to cool. The rolling bun lay and lay there. Suddenly it rolled off the window sill to the bench, from the bench to the floor, from the floor to the door. Then it rolled over the threshold to the entrance hall, from the entrance hall to the porch, from the porch to the courtyard, from the courtyard through the gate and on and on. The rolling bun rolled along the road and met a hare. "Little rolling bun, little rolling bun, I shall eat you up!" said the hare. "Don't eat me, slant-eyed hare! I will sing you a song," said the rolling bun, and sang: I was scraped from the cupboard, Swept from the bin, Kneaded with sour cream, Fried in butter, And cooled on the sill. I got away from Grandpa, I got away from Grandma, And I'll get away from you, hare!
endale aru andmata, mida nad tarvitavad ning millised võivad olla tagajärjed. Kuna inimeste organismid ja ainevahetused on üsna erinevad, siis on ka alkoholi ja uimastite koosmõju igale inimesele erinev. Kuna juba ainuüksi alkoholi tarvitamine mõjub igaühele erimoodi, on kahe või rohkema uimasti segatarvitamine väga ettearvamatute ja ohtlike tagajärgedega. Levinumad kombinatsioonid noorte hulgas on alkoholi ja kanepi, alkoholi ja ecstasy ning alkoholi ja (met)amfetamiini koos tarvitamine. Kanepi ja alkoholi segatarvitamine on nii füüsiliselt kui ka psüühiliselt ettearvamatute tagajärgedega. Alkohol kasvatab keha potentsiaali omastada delta-9- tetrahüdrokannabinooli (THC) ehk kanepitaime saaduste peamist psühhoaktiivset komponenti kiiremini. See võib aga viia mõnuaine üledoseerimiseni. Füüsiliste kõrvaltoimetena võib inimene kogeda situatsiooni nimega greening out, mis hõlmab endas iiveldust, pearinglust ja oksendamistahet

INTRODUCTION(pärast I videoklippi) I've decided to talk about Rowan Atkinson because he recently celebrated his 56th birthday and I haven't met a person who didn't like him. BIOGRAPHY Rowan Sebastian Atkinson, whose nickname is Row, was born on the 6th January 1955. He is a British actor, comedian and screenwriter. His trademark(kaubamärk) character is Mr Bean which most people probably know him by. Rowan grew up with his two older brothers in Newcastle, UK, where his father owned a farm. He attended Newcastle University and Oxford University where he earned degrees in electrical engineering
Everyone is unique in their own personal way. But a perfect friend has to be faithful, honest, fun and understanding. I think I have those qualities but I cannot judge myself. Because others may see me in a different way. True friends love us and care for us. They always make us feel special and never expect anything in return, other than our love and friendship. They stay true to us throughout their lives. Sandra has become one of my closest friends. I met her when we were in the second grade. But we became friends, I think, in the forth grade. At first we were just acquaintances but later when we got to know each other we started to hang out more often. Sandra is very beautiful. She has long brown hair and brown eyes. Sandra has a slim body and she is very tall. I think she has a a good taste of style. Sandra always dresses fashionably. Sandra is a very confident person. She is not afraid to speak her mind. She is also friendly

· Happelised oksiidid. Happelised oksiidid on oksiidid, mis reageerivad alustega moodustades soola ja vee. Happeliste oksiidide hulka kuuluvad enamus mittemetallioksiide ja need metallioksiidid, kus metalli oksüdatsiooniaste on IV või sellest suurem. Keemilised omadused: 1. Happeline oksiid + vesi = hape (veega ei reageeri Si02) SO3 + H20 =H2S04 2. Happeline oksiid + aluseline oksiid = sool (eelistatult reageerivad IA ja IIA met. oks.) S03 + CaO = CaS04 3. Happeline oksiid + alus = sool + vesi S03 + 2KOH = K2S04 + H20 · Aluselised oksiidid. Aluselised oksiidid on oksiidid, mis reageerivad hapetega moodustades soola ja vee. Aluseliste oksiidide hulka kuuluvad metallioksiidid, milles metalli oksüdatsiooniaste on tavaliselt I või II. Keemilised omadused: 1. Aluseline oksiid + vesi = alus (reageerivad ainult IA ja IIA met. oksiidid) K20 + H20 = 2KOH
up with the rapid development in this field. Other than my studies, I have been earnestly seeking for opportunities to gain understanding of my potential and the world around me. One of these experiences that I treasured was a study tour to Taiwan I made last year, in which I had to compete with 120 candidates to become one of the 40 participants in the tour. We visited the Legislative Council of Taiwan and met the vice president of the Council to understand the issues of their society. We also visited government departments and met the famous economist, Woo Jia Ching. From this tour, I have gained much insight about the Taiwan society. By comparing Taiwan and Hong Kong, I have also come to know more about the place I live in. After you have the opportunity to review my resume, I hope to have a chance to meet you to discuss further how I might contribute to Thomson Consulting. I look forward to
Friends and Friendship I have several friends. But my best friend is Anette. Anette is a little younger than i am- 14. I first met Anette when i was 8 years old, but we didnt become friends at first. Our fathers used to work together, so we first met each other in my fathers office. We became friends about 3 years ago, when Anette came to my traning group. It had been 3 years since we last saw each other so i didnt recognize her at first, and Anette did not recognize me either. So we bacame true friends without knowing that we had known each other for many years already. We found out that our fathers are friends about two yeas ago, when they met each
Character sketch Melanie Oranges are Not the Only Fruit Jeanette Winterson In Oranges are Not the Only Fruit Melanie was the first lover of the main character Jeanette. They were both religious and wanted to be missionaries. Jeanette described Melanie with words like sweet, lovely, beautiful, good and serene. Melanie had lovely grey eyes. Jeanette met Melanie at a fish stand. At first Melanie was reluctant to start a conversation with Jeanette, but eventually she caved in. Week after week Melanie worked at a fish stand boning kippers on a big marble slab and Jeanette went to watch her. Then, one week Jeanette didn't find her because Melanie had got a job in the library. She had to work there every Saturday morning. Melanie lived with her mother who often wasn't home. She had no father
Every year, thousands of people want to meet someone speacial or just a new friend. Unfortunately not all of us can make it work. Some of us just can´t break the ice between himself and the stranger. Here are few examples why politics and religion are not a safe topics to start a conversation with. On the one hand, starting a conversation with this topics can be safe, If both participants are not arguing, but just unbiased and discussing it. Everything depends of place, where you have met this new person. If you had met him somewhere at conference, where is suitable to talk about politics, then it could be fine. You can start a conversation with different questions like: "Hello, which political party you belong to?" - It would not be criminal. This person will answer you, if he wants to. Then you can keep on with your questions and try to promote this conversation. On the other hand, starting a conversation with topics like that in some public place is not very good
I read the book ,,The last song ", so to begin with the book told a story about 17 year old Veronica (called Ronnie )Miller´s life while her parents divorced and her father Steve moved from New York, where she lives to North Carolina, Wilmington. Steve was a concert pianist and teacher. She hasn´t met her father for three years and now her mother sent her and her brother Jonah to dad´s place, which was located near the beach. Ronnie was distant from her parents and especially from her father. In Wilmington she had a good time with her new friend Will, how she met at the beach while he was playing volleyball and run into her by accident, but Will was the last person she thought she'd ever be attracted to, and she found herself falling for him, opening

chamber. For the next nine months, Eva and her sister Miriam were housed in a rat-infested bunk with 300 other children and subjected to medical experiments daily. Despite the daily torture, Eva was determined to survive. When liberation finally came on January 27, 1945, Eva and Miriam were at the front of the line as the children were led out of Auschwitz. Renee Firestone survived by using her skills as an aspiring designer to throw off the Nazis. After Auschwitz she met her brother and moved to Prague. She was a famous fashion designer and later on she and her brother moved to U.S. Martin Greenfield survived the bitter cold of the death march by wearing layers of discarded Gestapo uniform shirts he obtained while working as a tailor in Auschwitz. He was 14 when he was forced going to Auschwitz. He got tattooed with his father. He listened to his father´s advice. He was beaten up when he purposely ripped the shirts. After Auschwitz he got a job as a tailor
