课时作业
Ⅰ.阅读理解
(2025·安徽合肥第一次教学质检)It was my birthday, and I was celebrating it as I had for years: Watching the annual Perseid meteor shower (流星雨).But this time, as the meteors flashed across the sky, I, a junior girl, began to question, “Could my lifelong love for astronomy be more than a hobby？”
I grew up in a small town, where even graduating from high school was not a given for many students.But I was driven to pursue my education, and like my best friend’s dad—a pharmacist (药剂师), one of the few professional role models in my neighborhood, therefore, I chose to major in pharmacy, the science of preparing medicines, at the University of North Carolina.
The university was only a 3.5-hour drive away, but it felt like traveling across the universe.In the weeks since I began my pharmacy degree, I had met people with jobs and PhDs in different branches of science I had never considered—neuroscience, archaeology, and even astrophysics.Their passion and knowledge opened my eyes to worlds I had never imagined. As my birthday and the Perseid meteor shower approached, I was faced with a decision: Should I stick to my long-standing plans or take a step into the unknown
Ultimately, a solar eclipse (日食) helped me make my decision.As the moon gradually shaded the sun, the world darkened around me.The stillness of the water, the desperate calls of birds, and the fading sunset deeply moved me.I knew what I had to do.I dropped out of pharmacy school to pursue previously unimagined options.
Facing years of challenges and growth, I worked odd jobs before earning a second degree in physics, starting a PhD in astronomy, and realized that the night sky’s vastness inspired me to overcome doubts and follow my dreams.As I approach the final year of my PhD, I realize that growing up with the night sky gave me a valuable gift.It gave me an insight into life: On the scale of our vast universe, our individual needs, desires, fears, and insecurities shrink to insignificance, bringing humanity together.It liberated me from allowing earthly worries, shame, or self-doubt to stand in the way of pursuing new dreams.
[语篇解读]　本文是一篇记叙文。文章讲述了一个年轻女孩在生日那天观看流星雨时，开始思考自己对天文学的热爱是否能进一步发展。在大学里，她接触到不同的人群，后来又被日食的情景启发，最终决定追求天文学的梦想。
1.What motivated the author to major in pharmacy
A.Her ambition to become a doctor.
B.The encouragement of her friend.
C.Her childhood passion for pharmacy.
D.The influence of her best friend’s father.
答案：D
解析：细节理解题。根据题干中的pharmacy可将答案定位至第二段。根据第二段中的“I was driven to pursue my education, and like my best friend’s dad—a pharmacist, one of the few professional role models in my neighborhood, therefore, I chose to major in pharmacy”可知，作者最好的朋友的父亲是一名药剂师，他是作者所在社区中为数不多的职业榜样之一，因此，她选择主修药剂学。所以作者是受到了好朋友的父亲的影响才主修药剂学。故选D。文中有逻辑关系词therefore。
2.How did the author’s experience at university shape her
A.It helped her stick to her belief.
B.It opened her mind to new ideas.
C.It enhanced her pharmacy study.
D.It developed her thinking abilities.
答案：B
解析：推理判断题。 根据第三段中的“In the weeks since I began my pharmacy degree, I had met people...Their passion and knowledge opened my eyes to worlds I had never imagined.”可知，作者在大学期间遇到了来自不同职业的人和不同科学领域的博士，这些人的热情和学识让她看到了她从未想象过的世界。这表明大学经历开阔了她的眼界，使她接触到了新事物。故选B。
3.What can we learn from the author’s understanding of life
A.Accepting insecurities helps us handle challenges.
B.Personal problems still matter in the vast universe.
C.It’s vital to pursue dreams despite personal challenges.
D.It is small and unimportant things that mean a lot to us.
答案：C
解析：推理判断题。 文章最后一段描述作者追寻梦想过程中的感悟，根据其中的“It gave me an insight into life...It liberated me from allowing earthly worries, shame, or self-doubt to stand in the way of pursuing new dreams.”可知，作者通过自己的经历认识到，在广阔的宇宙中，我们的个人需求、欲望、恐惧和不安都变得微不足道，这让全人类紧密相连。它让作者摆脱了世俗的烦恼、羞愧或自我怀疑，不再让它们阻碍自己追寻新的梦想。这表明尽管面临个人挑战，追寻梦想仍然至关重要。故选C。
4.Which of the following best describes the author
A.Caring and patient.
B.Modest and honest.
C.Generous and helpful.
D.Curious and determined.
答案：D
解析：推理判断题。根据第三、四段可知，作者在大学期间，接触到了不同的人群，经过认真思考后决定踏入新的领域，这体现出她对新事物充满好奇，愿意探索不同的可能性。根据最后一段中的“Facing years of challenges and growth, I worked odd jobs before earning a second degree in physics, starting a PhD in astronomy”可知，作者在决定追求天文梦想之后，面临了诸多挑战，并坚持了下来，坚定地朝着自己的目标前进，这充分体现了她意志坚定的品质。故选D。
Ⅱ.阅读七选五
Astronauts on the International Space Station often spend 6 to 12 months in space. It is hard to stay inside the space station all that time, but they still need to manage their everyday living, such as working, eating, and exercising with limited resources. Imagine you are an astronaut on the space station right now. 1
Keep learning
Astronauts are constantly learning. They do all the science experiments that need to be carried out on the space station. Most of the time, these experiments were designed by scientists. 2 Astronauts also need to learn how to operate parts of the space station, such as the robotic arm.
Do exercise
3 One way they do this is by running on a designed treadmill (跑步机), which could hold them down so they won’t float away. You can keep your muscles strong, too. Do some push ups, sit ups or jogging so that you’ll be strong enough when you can go exploring.
Observe Earth
Astronauts love to take pictures and videos of Earth from the window of the space station. 4 You can take pictures from your window, too. Think about what makes your street and city special and take notes of the patterns you see.
Stay in touch
Astronauts keep in touch with their families by email and video-conference. You can keep in touch with your family and friends in the same way. Make a list of the friends and relatives you want to stay in touch with and contact a few every day. 5
A.What do you know about astronauts
B.What activities would you do in space
C.They will be glad to know you are thinking about them.
D.Astronauts need to keep their muscles strong to stay healthy.
E.Astronauts are learning how to grow food on the space station.
F.So they need to learn about the science by following the right steps provided.
G.Seeing Earth in a new way gets them thinking about what makes our planet unique.

课时作业15 UNIT 4 SPACE EXPLORATION
Ⅰ.阅读理解
(2025·安徽合肥第一次教学质检)It was my birthday, and I was celebrating it as I had for years: Watching the annual Perseid meteor shower (流星雨).But this time, as the meteors flashed across the sky, I, a junior girl, began to question, “Could my lifelong love for astronomy be more than a hobby？”
I grew up in a small town, where even graduating from high school was not a given for many students.But I was driven to pursue my education, and like my best friend’s dad—a pharmacist (药剂师), one of the few professional role models in my neighborhood, therefore, I chose to major in pharmacy, the science of preparing medicines, at the University of North Carolina.
The university was only a 3.5-hour drive away, but it felt like traveling across the universe.In the weeks since I began my pharmacy degree, I had met people with jobs and PhDs in different branches of science I had never considered—neuroscience, archaeology, and even astrophysics.Their passion and knowledge opened my eyes to worlds I had never imagined. As my birthday and the Perseid meteor shower approached, I was faced with a decision: Should I stick to my long-standing plans or take a step into the unknown
Ultimately, a solar eclipse (日食) helped me make my decision.As the moon gradually shaded the sun, the world darkened around me.The stillness of the water, the desperate calls of birds, and the fading sunset deeply moved me.I knew what I had to do.I dropped out of pharmacy school to pursue previously unimagined options.
Facing years of challenges and growth, I worked odd jobs before earning a second degree in physics, starting a PhD in astronomy, and realized that the night sky’s vastness inspired me to overcome doubts and follow my dreams.As I approach the final year of my PhD, I realize that growing up with the night sky gave me a valuable gift.It gave me an insight into life: On the scale of our vast universe, our individual needs, desires, fears, and insecurities shrink to insignificance, bringing humanity together.It liberated me from allowing earthly worries, shame, or self-doubt to stand in the way of pursuing new dreams.
[语篇解读]　本文是一篇记叙文。文章讲述了一个年轻女孩在生日那天观看流星雨时，开始思考自己对天文学的热爱是否能进一步发展。在大学里，她接触到不同的人群，后来又被日食的情景启发，最终决定追求天文学的梦想。
