Ⅰ. 次の英文を読んで、下の間に答えよ。 Early in the pandemic, Julie Van Rosendaal started to notice something (1) about the butter she was using in her cooking and baking. It seemed harder than it used to be. Van Rosendaal has a food blog (2) DinnerWith.Julie.com. She talks about food on CBC radio and writes about it in magazines and newspapers. Before, when she left butter out of the fridge, it used to go soft; it was easy to spread on bread. (3) these days, she noticed that if she wanted soft butter, she had to put it in the microwave. If she used it right out of the cupboard, it would tear holes in her bread. Was her kitchen too chilly? Or had something about Canadian butter changed? On Feb. 5, Van Rosendaal posted her suspicions on social media. More than a thousand people on Facebook and hundreds on Twitter commented that they had been noticing the ( 4 ) thing. The answer seems to be that Canadian dairy cows, which produce the milk that is made into Canadian butter, (5) likely being fed more palm oil fats in their feed than before, XV As more people began doing more baking and bread making during the pandemic, the demand for butter went up. Using palm fats in livestock feed can increase the amount of milk cows produce, which helps farmers to meet the increased demand for ( 6 ). Some people don't want palm fats in their diet, because they say it isn't heart-healthy. (7) say it changes the taste and texture of

1. 次の英文を読んで (1) ~ (5) の問いに答えなさい。 Have you ever dreamed of traveling in space? I have thought of going into space as an astronaut so many times. Traveling beyond the earth is always a great dream and hope for humanity. But as everyone knows, it is not easy to be an astronaut. There are many people who want to try to get into space flight programs all around the world. So first, you have to pass extremely difficult selection processes to even participate in the training and testing used to prepare potential astronauts for operating in and living F ) in space. The training itself is so hard that it is very difficult (A) complete. ( those that pass the training, only a few can actually experience the trip into space. Every time I see the news about the manned space flights on TV, it does sound like something impossible for a regular person like me. (G ), there was a recent event that really surprised me in September 2021. They 2completed said that ("Crew Dragon" 3the 3 day-mission 5called) the spacecraft successfully. As a surprise, this mission was an "All- Civilian" flight. The four people in the Crew Dragon were not professional astronauts from other space agency programs. A billionaire booked the Crew Dragon capsule last year and picked three normal people to ride (B) him. It was the VERY first totally private mission to orbit. The stories of how the people had been chosen and how the trip succeeded were not only amazing but also very heart warming. Watching this news reminded me (C) the excellent idea about Space elevators. This is a promising scientific technology that could take us into space much more (K) in the future. ( H ) JSEA (Japan Space Elevator Association), the concept of a Space elevator would make reaching orbit in space easier and faster (D) using Centrifugal force and Earth's gravity instead of rockets. Engineers estimate it requires a cable that is about 100,000km long and more than 100 times as strong as steel. So of course, it sounds like a challenging development. Also, the space elevator would require much less energy to lift cargo and people into orbit and be significantly more eco-friendly. As they continue to work on advancing technology, the space elevator may become a reality (E) we know it. With the space elevator, traveling into space would no longer be an impossible dream for us, ordinary people. Just talking about it, I get totally excited and can't help hoping to experience the situation of looking down on the earth from the space one day. (E)に入る前置詞として適切なものを①から⑤か (1) 本文中の(A) らそれぞれ選びなさい。 Dwith 2to 3before 4 by 5 of P.1
