One great way to make use of the extra time is to go on an adventure and travel. Clearly, I am not a naturally adventurous person, but I have found that takingthe risk and challenging myself to explore and travel to unfamiliar places can be a very rewarding experience.Because I am usually quite busy during the school year, most of my travels take place during the summer. Over the past few summers, I have hiked in the Grand Canyon, explored Niagara Falls, and camped out in upstate New York. Although these experiences are varied, they are similar in that they instill (灌输) a sense of appreciation for nature and a more balanced view on life. When I hiked in the Grand Canyon, for example, I was in awe(敬畏) of the geological influences that shaped the canyon.Adventures, of course, are not limited to hiking. There are many other choices, such as camping, volunteering in a foreign environment and travelling to different countries. In my opinion, adventures are more enjoyable with family or a few friends. There is a sense of bonding that one only gets through spending time together in outdoor adventures. For example, when I was in Boy Scouts, I often went on weekend camping trips with my friends. When I came back from a Boy Scouts camping trip, I often was eager to go outside more and explore the parks and nature around me.Next fall, I will attend college. In the meantime though, I hope to make the most of my summer to exploreand travel. Now, I am planning on hiking and camping out in Maine.When I visited Maine last fall, I was amazed by how beautiful it was and the tall trees and coasts that exist, and I really hope to enjoy the beauty of nature there this summer.4. We can learn from the first paragraph about the author?A. He is an adventurous person by natureB. He likes challenging himself by travellingC. He enjoys travelling with other adventurersD He needs others’ help when going on an adventure5. Which of the following can make people’s adventure more enjoyable according to the author？A. Going to different countries.B. Going to unfamiliar places.C. Travelling withtheir family or friends.D. Travelling to distant places by themselves.6. What will the author do this summer？A. Explore Niagara Falls.B. Hike in the Grand Canyons.C. Camp out in upstate New York.D. Hike and camp out in Maine.7. Who is probably the author?A. A high school student.B. A college student.C. A friendly guide.D. A warm-hearted teacher.CThe Jewish(犹太人）family-had-just finished supper and the woman had placed the dishes in the sink.The kitchen was quite damp and even gloomier than in the main room.It was their third apartment since the start of the war,they had abandoned the other two in a hurry.The woman came back into the room and sat down again at the table.The 3-year-old boy sat with his back straight,his eyes fixed on his father,but it was obvious that he was so sleepy that he could barely sit up.The man was smoking a cigarette.His eyes were blood-shot and he kept blinking in a funny way.This blinking had begun soon after they fled the second apartment.It was late,past ten o'clock and they could have gone to sleep,but first they had to play the game that they had been playing every day for two weeks.Even though the man tried his best and he moved very quickly,the fault was his and not the child's.The boy was.marvelous.Seeing his father put out his cigarette,he opened his blue eyes even wider.The woman,who didn't actually take part in the game, stroked the boy's hair.“We'll play the key game just one more time only today.Isn't that right?"she asked her husband.He didn't answer because he was not sure.They were still two or three minutes off.He arose and walked towards the bathroom door.Then the woman called out softly,“Ding-dong."At the sound of the bell ringing so musically from his mother's lips,the boy jumped up from his chair and ran to the front door,which was separated from the main room by a narrow corridor.“Who's there?"he asked.The woman,remaining in her chair,shut her eyes tight as if feeling a sudden, sharp pain.“I'l1 open up in a minute,I'm just looking for the keys,"the child called out. Then he ran back to the main room,making a lot of noise with his feet.He ran in circles around the table,pulled out one of the sideboard drawers,and slammed it shut.“Just a minute,I can't find them,I don't know where Mama put them,"he yelled,then dragged the chair across the room,climbed onto it,and reached up to the top of the shelf.“I found them!”he shouted triumphantly.Then he got down from the chair, pushed it back to the table,and calmly walked to the door and opened it.“Shut the door,darling,"the woman said softly."You were perfect.”The child didn't hear what she said.He stood in the middle of the room,staring at the closed bathroom door.“Shut the door, the woman repeated in a tired flat voice.Every evening she repeated the same words,and every evening he stared at the closed bathroom door.At last it opened.The man was pale and his clothes were streaked with lime and dust.He stood there,eyes blinking in that funny way.“Well?How did it go?"asked the woman.“I still need more time.He has to look for them longer.I slip in sideways allright,but then...It's so tight in there that when I turn...And he's got to make more noise-he should stamp his feet louder."The child didn't take his eyes off him.“Say something to him,"the woman whispered.＂You did a good job,little one,"he said mechanically.“That's right,”the woman said,“you're really doing a wonderful job,darling. You act just like a grown-up.And you do know that if someone should really ring the doorbell when Mama is at work,everything will depend on you?And what will you say when they ask you about your parents?”“Mama's at work.”“And Papa?"He was silent.“And Papa?"the man screamed in terror.The child turned pale.“And Papa?”the man repeated more calmly.“He's dead,”＂the child answered and threw himself at his father,who was standing right beside him,but already long dead to the people who would really ring the bell.8. What does the underlined sentence in Para.5 mean?A. The family needed to practise the game for another 2 or 3 minutes.B. There was still 2 or 3 minutes left before someone knocked at the door.C. They would become too sleepy to play the game 2 or 3 minutes later.D. The father needed 2 or 3 more minutes before the kid opened the door.9. Why did the boy make a lot of noise when he was looking for the key?A. Because he needed to drown out the noise caused by his father.B. Because he was too little and just couldn't control his footsteps.C. Because he was too anxious to find the key to open the door with.D. Because he met many barriers on his way to where the key was.10. In Para.12,why did the mother repeat“shut the door”in a tired,flat voice, instead of the previous soft one?A. She was angry because her son didn't close the door as he had been told to.B She felt anxious because she knew her husband would be annoyed at the boy again.C. She was disappointed because the boy's movement betrayed again where her husband was.D. She was impatient because she was asked to repeat these words again and again every evening.11. What is the best title of the passage?A. A Scary NightB. The Key GameC. My Father Is DeadD. An Innocent BoyDAs I was walking home，a boy seemed to be singing a song in a very low voice，walking infront of me and carrying some of the same high school books I had with me.I caught up to him，and said “Hello”．I could tell he wasstartled，and dropped one of his books.I picked it up and as I handed it to him，he said “Thank you.” in a strange way，like witha strong accent.We soon began walking together and talking.It turns out he was in my science class，and I didn’t even know it!His name was Ahmad，and his family had just moved here this school year.He invited me into his house，andhis family treated me like a special guest，which made me feel very welcome.He said hospitality (好客) is very basic to his culture，and strangers were always treated very kindly.His mom brought out some great food，and offered me some tea.Ahmad’s father and two sisters wanted to hearall about me and my family，and my schooling.Ahmad’s whole family had to leave their lifelong home because war had broken out，and it wasn’t safe there anymore.They left with only what they could carry.His family was happy to feel safe，and they got used toAmerican culture quickly.They seemed pleased that Ahmad had brought a friend home to meet them.And as my friendship with Ahmad has continued，I now realize that the world is so much bigger than I thought！I also realize that your friends don’t have to be just like you.Differences make the world go round.12. What does the underlined word “startled” in Paragraph 1 mean?A. Excited.B. Moved.C. Surprised.D. Interested.13. Why was the writer treated like a special guest by Ahmad’s family?A.
