Last month,our class held an upcycling workshop.We brought old jeans,scissors, needles and thread.Our teacher showed us how to make a simple bag.First,we cut off the legs of the jeans.Then we sewed the bottom closed.Next,we used the leftover fabric to make straps.Finally,we decorated the bag with buttons and patches. I made a blue denim bag with a red heart patch.It was not perfect,but I felt proud because I created something useful from something old.Now I use it to carry my books to school.Some classmates made pencil cases or phone holders.Everyone was surprised at how much we could do with old clothes. Upcycling not only reduces waste but also encourages creativity.The best part is that you don't need to be an expert.With a little imagination,anyone can give old things a second life. ()1 What is the difference between upcycling and recycling? A.Upcycling changes materials completely B.Upcycling uses more energy than recycling. C.Upcycling reuses items without breaking them down. D.Upcycling only works with old clothes. ()2 How did the writer make the bag? A.She cut off the legs and then added straps. B.She sewed the bottom first and then cut the legs. C.She used the whole jeans without cutting. D.She asked the teacher to do everything. ()3 What does the underlined word "leftover"in Paragraph 2 mean? A.剩余的 B.左边的 C.丢失的 D.喜欢的 ()4 Why did the writer feel proud? A.Because her bag looked perfect. B.Because she saved money. C.Because she made something useful from old jeans. D.Because her classmates liked her bag. ()5 What is the main purpose of this passage? A.To teach people how to sew a bag. B.To encourage people to try upcycling. C.To show what students can make in workshops. D.To explain why old clothes are valuable. D篇 Have you heard of makerspaces?They are special places where people can create, invent and learn by doing.Many schools now have makerspaces with tools like 3D printers,sewing machines and woodworking tools. At our school,the makerspace is open every Friday afternoon.Last week,I decided to make a wooden birdhouse.First,I drew a design on paper.Then I used a saw to cut the wood into pieces.It was harder than I expected.The wood kept slipping,and my cuts were not straight.Mr.Chen,the teacher,showed me how to use clamps to hold the wood still.That helped a lot. Next,I sanded the edges to make them smooth.After that,I hammered nails to join the pieces together.I made a small round hole for the birds to enter.Finally,I painted the birdhouse blue and white.When I finished,it looked a little crooked(歪斜的)，butI was still proud of it. In makerspaces,students learn not only skills but also problem-solving.For example, when my birdhouse roof didn't fit well,I had to measure again and cut a new piece. Making mistakes is part of the learning process.Every failure teaches you something new. Makerspaces are becoming popular because they make learning fun and hands-on. Instead of just reading textbooks,students can build real things.Maybe you could start a makerspace in your school too! ()1 What is a makerspace according to the passage? A.A classroom for reading. B.A library with many books. C.A workshop for creating things. D.A playground for sports. ()2 What problem did the writer meet when cutting wood? A.The saw was too old. B.The wood kept slipping. C.Mr.Chen didn't help him. D.He ran out of wood. ()3 How did the writer solve the problem? A.He used a different saw. B.He asked a classmate for help. C.He used clamps to hold the wood. D.He gave up making the birdhouse. ()4 What can we learn from this passage? A.Making things is easy and fast. B.Mistakes are not allowed in makerspaces. C.Hands-on learning helps students grow. D.Birdhouses must be perfect to be useful. ()5 Why does the writer write this passage? A.To introduce what a makerspace is. B.To share his experience of making a birdhouse C.To show that makerspaces are better than classrooms. D.Both A and B. 二、完形填空 Dear Amy, How are you?I'm writing to tell you about our school's "Hands-on Fun"activity last weekend.It was 1. amazing experience.
