Courtney Dressing was just 15 years old when she joined a team of space researchers. Those scientists landed NASA's (美国宇航局) robot rover (机器人探测器), Spirit, on the planet Mars. But this was neither Courtney's first nor her last adventure in space research. When she was in fifth grade, Courtney had 75 decided to spend her life exploring the universe. She checked out space books from her library, studied hard in math and science classes, and later, attended United States Space Camp in Alabama.
Then Courtney 76 to become part of the Student Astronaut program. After a lot of hard work, interviews, and months of waiting, Courtney won. She was at the laboratory in California with NASA scientists when Spirit reached Mars.
"The most 77 part took place late at night on January 3, 2004, when we received signals showing that Spirit had 1anded successfully." Courtney says, "I joined the rest of the scientists in jumping up and cheering."
It took Courtney seven nights to work with and learn from the NASA scientists. They worked at night 78 that was daytime on Mars. They studied the photographs that Spirit was ending to Earth of Gusev Crater on Mars. They spoke to television reporters at NASA press conferences and attended meetings in which the NASA team named the rocks and hills the Spirit was finding.
When Courtney was 17 years old, she went to work for NASA as a student intern (实习生) at the Space Fight Center in Maryland. With two NASA scientists, Courtney worked on a project that might one day help future astronauts find other planets 79 Earth, where human beings could live.
Courtney says her favorite part of these space adventures is working side by side with the best scientists and feeling like a part of the team.

The following are six film r 81 from the students.
The Girl in Black is a story about something that happened 400 years ago. Two young people meet and fall in love but the young man has to go away to fight in a w 82 . The story has a good beginning but then nothing really happens.
The Circle of Life is a film everyone should see if they want to go home feeling cheerful. I couldn't stop 1 83 . There is one sad part in the middle but everything is all right in the end. Jules Verity, the star, normally sings and dances in films, so this is a change for him.
The clothes the actors wear in Cramer Place are lovely. It is a true story which takes place in the nineteenth century in an old house. It is actually difficult to believe this really happened and I found it i 84 to guess the ending-you just have to wait and see. The acting is wonderful.
The Blue Country is an action film with a difference because it is also funny u 85 the end when everyone dies. Most of the action actually comes at the end and I did find the first half a little boring.
I hadn't heard of any of the actors in the Lost Journey but I'm sure we'll see them again. The film takes place on a small planet in the future. It is rather difficu.t to believe but.it has a good story and is w 86 acted. L loved the ending which I hadn't expected.
The Path to Nowhere is the latest in a series of films starring Des Riley and Tom Carver. It starts with a car chase, there is plenty of action in the middle and it finishes with a helicopter following the two men as they try to escape in a boat. I couldn't wait to d 87 what happened.
D. Answer the questions（根据短文内容回答下列问题）（共12分）
I'm Aimswell, a boy, and I live on the island of Tobago in the West Indies. Like many people here, my father is a fisherman and he taught me to fish when I was about five. I love it and have even won some prizes in fishing competitions. Local people here fish for themselves and some of them even supply fish to big hotels. Recently everyone has started to notice that there are not as many fish in the sea as they used to be and the fish that we are catching now are really small, still young. If everyone keeps catching all the fish when they are so young, we may soon run out.
I'm working on a programme at my school to find a way for people in Tobago to be able to continue eating fish without make the ones in the sea rare. My teacher, Mr. Peters, started it a little while ago. The project is teaching all the kids in my school about fishing sustainabl y. This means we can eat fish without running out in the future. We are farming a freshwater fish called tilapia (罗非鱼) which people can grow in tanks in their homes and gardens, instead of catching lots out of the seas.
We look after the fish during our agricultural science lessons. It's my favourite lesson because we get to go outside and work in our school vegetable garden and look after the fish. I am in charge of the fish at the moment. I give them food-water plants which we grow here. Mr. Peters hopes that when all the kids at my school go home and show their parents how we have grown fish at school, they can do the same at home. He hopes that one day everyone in Tobago will be able to do it.
I love working on the project because it is fun. More importantly, it teaches us business skills and ways to help protect the environment.
Soon our fish will be big enough to eat and then we will learn some nice recipes so we can cook and enjoy them at last.
88. Aimswell is good at fishing, isn't he?
89. Who do local people fish for?
90. What does "fishing sustainably" in paragraph 2 mean?
91. Where can people grow tilapia?
92. How can children help their parents grow the fish?
93. What do you think of the programme? Why? What else can they do to make the programme
better?
Ⅶ．Writing（作文）（共20分）
94. Write a passage of at Ieast 60 words on the topic “I want to say sorry to ______”.
（根据提示，以“我想对__—说对不起”为题，写一篇不少于60个词的短文，写作前先将题目补充完整。标点符号不占格。）
提示：在学习、生活中，每个人都难免会做错一些事，这些事总会让人感到遗憾或后悔。
请结合你的亲身经历，谈谈你的感触。

8．小宇在水中先放入大量食盐，待食盐不再溶解后，盐水密度为ρ，再放入鸡蛋，观察到鸡蛋处于漂浮状态，如图4（甲）所示。液体静置一段时间后，此时盐水密度仍为ρ，她发现鸡蛋下降至图4（乙）所示位置。对此过程的判断，正确的是 ( ) A 液体对容器底部压强变大，鸡蛋受到浮力不变、重力不变 B 液体对容器底部压强不变，鸡蛋受到浮力变小、重力变小 C 液体对容器底部压强变大，鸡蛋受到浮力变大、重力变大 D 液体对容器底部压强变大，鸡蛋受到浮力变大、重力不变 9．如图5所示的电路中，电源电压保持不变，电阻R 1的阻值为10欧，变阻器R 2上标有“20欧1安”的字样。闭合电键S 后，在滑动变阻器的滑片从R 2的最左端向最右端移动过程中，关于两电压表示数之差大小的变化情况，下列判断中正确的是 ( ) A 始终变大 B 始终变小 C 先变大再变小 D 先变小再变大 10．如图6所示，A 、B 两个相同的薄壁轻质柱形容器放在水平地面上，两容器中分别盛有相同深度的水和酒精。现将甲、乙两个完全相同的小球分别轻放入A 、B 两容器中，设甲球放入A 容器后水对容器底部的压强增加量为Δp 水，乙球放入B 容器后容器B 对地面的压强增加量为Δp 容。已知Δp 水 ＝Δp 容，下列说法可能正确的是 ( ) A 若水不溢出，酒精溢出，则甲球漂浮，乙球沉底 B 若水不溢出，酒精溢出，则甲、乙两球都沉底 C 若水和酒精都溢出，则甲球漂浮，乙球沉底 D 若水和酒精都溢出，则甲、乙两球都沉底 二、填空题 （共29分） 11．地球周围的一层厚厚的大气由于受到 的作用，会对处于其中的物体产生压强， 这个压强叫做大气压强。奥托·格里克做了著名的 实验证明了大气压强的存在且很 大。通常海拔越高，大气压强越 。 12．钛合金是航空工业的重要材料，它的密度是4500千克/米3 。用钛合金制造神州十一号的某零件，其体积为1×10-4 米3，则质量为 千克。若再将该零件进行打磨，其质量 ，密度 （均选填“变大”、“变小”或“不变”）。 13．某导体电阻为20欧，通过它的电流为0.2安，5秒内通过该导体横截面的电荷量为 库，它两端的电压为 伏。当通过此导体的电流为0.5安时，它的电阻为 欧。 图5 图4 A B 水 酒精 图6
