My mother had never used a mobile phone until she    1     (receive)one for her birthday this year. Since then, she has been    2     (addict) to the Internet, using different kinds of     3     (软件) applications. She spends a lot of time each day    4    (explore) websites and chatting with other people online. She has set up her own email    5    (账户)and she does most of the shopping online through a dvice. Instead of going to supermarkets, nowadays she just     6     (press) a button and then her orders are     7     (deliver) the next day. At first, my father had some concerns     8     she was spending too much time in virtual worlds, but now he sees how happy she is. She even    9    (下载)some materials that can help my father with his work, so now he’s very happy, too! We are all very    10    (自豪的)of her as she has proven that it’s never too late to learn a new skill.

Hector stood in the front of his fifth-grade classroom as one of the last two competitors in the Room Five Geography Bee. His o    1     (对手) having missed the last question, it was Hector’s turn. If he answered his question correctly, he would be the Room Five champion.

“Where did I put that second sheet of questions?” Mr. Adler w    2     (私语) while searching through a thick pile of papers on his messy desk. Mr. Adler, though a great teacher, had a r    3     (名声) of being disorganized with a long history of misplacing things. “Oh well, I apologize for the d    4     (延误),” said Mr. Adler after what s    5     (好像) like a long time. “Hector, please tell us the c    6     (首都) city of Brazil.” Hearing the question, Hector smiled. Then, there was the answer.

Later that day in the courtyard, many classmates c    7     (祝贺) Hector. Wearing a proud smile, he g    8     (同…打招呼) and thanked them all. Oh, the sweet taste of victory.

As it was getting late, the courtyard became deserted. But Hector still didn’t want to l    9     (离开). Then he saw Mr. Adler c    10     (穿过) the courtyard and holding a half-open bag full of papers. As he h    11     (匆匆) past, an envelope dropped out but Mr. Adler was unaware. He turned a corner and d    12     (消失) out of sight. Hector picked it up. On the envelope were the words “Fifth Grade Geography Bee Questions and Answers”. Hector s    13     (盯着看) wide-eyed at the envelope. Before he even had time to reflect on the consequences, he opened it and read the questions.

As soon as Hector had done it, he k    14     (知道) it was the wrong choice. He’d c    15     (作弊) and whatever he did now, he couldn’t change the fact. “What if Mr. Adler thought I s    16     (窃取) this morning’s questions too?” Hector thought. “He’d take away my Room Five victory for sure.” Little did he know that one of the best days in his life would be turned into the worst so quickly. Torn by his conscience, Hector was t    17     (完全) at a loss what to do.

Before he realized it, Hector found himself standing in Mr. Adler’s room. He saw Mr. Adler searching for something on his messy desk. “Mr. Adler, are you looking for this?” he asked, holding the open envelope. “Oh, that’s e    18     (正是) what I’m looking for!” Mr. Adler said, “but what on earth is the matter?” Looking at the confused e    19     (表情) on Mr. Adler’s face, Hector got up the c    20     (勇气) to tell him the truth. To his surprise, Mr Adler actually p    21     (表扬) him for his integrity and wished him good l    22     (运气) in the next day’s competition.

The next day the entire school came to watch the Fifth Grade Geography Bee. Besides being g    23     (内疚的), Hector was puzzled at Mr. Adler’s reaction yesterday. But soon he felt relieved to find that the questions had been changed. He could i    24     (想象) Mr. Adler working late last night to prepare the new questions, grateful from the bottom of his heart for what Mr. Adler had done for him. When it was his turn, he c    25     (集中) his mind and answered all the questions correctly, becoming the final’s champion. The final gave Hector the sweet taste of victory again.

Sarek’s mountains used to be covered by vast sheets of ice. Around 9.000 years ago; this ice melted, leaving behind about 100 g    1    . Soon after, reindeer began to arrive. Following the reindeer were the Sami people, who made this t    2     their home. Getting here is quite difficult, so apart from the Sami very few people have ever seen Sarek. In 1909, Sarek was made a national park in order to keep the land in its n    3    state. Though the Sami are allowed to continue their traditional way of life in the park, no one else can live here, and all new development is b    4     within park boundaries. At the far side of the valley, an ancient Sami cottage is v    5    . Close by, there are a few reindeer feeding on grass.

For hundreds of years, looking after reindeer was a way of life for the Sami. They used the reindeer's meat for food, their bones for tools, and their skin for making clothes and tents. Since reindeer were always on the move, the Sami would pick up their tents and a    6    them. Today, most Sami have houses in villages near Sarek and live a m    7    life just like their neighbours. But every spring, a small number of Sami still follow their reindeer into the v    8    of Sarek, living in tents or old cottages and enjoying their traditions. I am not a Sami, but in Sarek I've a    9    some of their habits. For example, this morning my breakfast is flat bread warmed over a fire, dried reindeer meat, and some sweet and s    10    berries that I found growing near my tent.

The Renaissance (from the 14th to the 17th century)

New ideas and values gradually replaced old ones from the Middle Ages. As a result, painters c    1     less on religious themes. They began to a    2     a more humanistic attitude to life. An important b    3     during this period was the use of perspective by Masaccio. I    4     painters such as Leonardo da Vince, Michelangelo, and Raphael built upon Giotto and Masaccio’s innovations to produce some of the greatest art that Europe had ever seen.

Another innovation was the use of oil paints. With their deep colors and realism, some of the best oil paintings look like photographs. While painters as early as Da Vinci had used oil, this technique reached its h    5     with Rembrandt, who gained a r    6     as a master of shadow and light.

In subject matter, the emphasis increasingly s    7     from religious themes to people and the world around us. Kings, n    8    , and people of high rank wanted to p    9     accurate pictures of themselves and the people they loved. Others wanted paintings showing important historical events or stories from mythology. Finally, most c    10     wanted paintings that were beautiful and interesting to look at.

China is w    1     known for its ancient c    2     which has continued all the way through into modern t    3    , despite the many ups and downs in its history. There are many reasons why this has been possible, but one of the main f    4     has been, the Chinese w    5     system.

At the b    6    , written Chinese was a picture-based l    7     . It d    8     back several thousand years to the use of longgu-animal bones and shells on which s    9     were c    10     by ancient Chinese people. Some of the ancient symbols can still be seen in today’s hanzi.
