中学生 英語 長文です。 このような長文が全くと言っていいほど分かりません。 どのように解き進めていけばいいのでしょうか。 写真は愛知県マーク模試第4回のものです。

第4回愛知・中3英語 4 次の文章を読んで あとの (1)から(5)までの問いに答えなさい。 Where do you usually buy things? Do you go to stores near your house? Do you visit websites and click "buy now"? Today, many people order some products through the internet and have them delivered to their houses. It's convenient to get delicious food or interesting goods from all over Japan without (A) far from home. Then, have you ever thought about the system of carrying these products? Trucks are the main way of transportation. There are different sizes of trucks and they can go to all types of places. Carrying products by truck is necessary for people's lives. However, they produce a lot of CO2. They produce less CO2 than before and they're becoming more eco-friendly, but just using such trucks is not enough to reduce CO₂ because more trucks are needed to carry more products. To solve this problem, the modal shift began. The modal shift is to change the way of transportation partly from trucks to trains or ships. CO2 produced by trains or ships is less than that by trucks. When you think about the environment, it is better to use trains or ships. There are other good points of the modal shift. When products are carried by train or ship, the cost of transportation goes down. Trains or ships can usually carry more products than trucks. So, I needed to the cost / carry / decrease / will products I as a result. Another good point is the smaller number of operators. Each truck needs one driver. After all, a lot of truck drivers are needed. Trains and ships can carry more products than trucks and they need fewer operators. 1 There is, however, a disadvantage of the modal shift. Trains can move only between stations, and ships can move only between ports. They can't carry products from factories to shops or homes. Products are moved from trucks to trains or ships and from trains or ships to trucks. This takes a lot of time. The modal shift is not a good way to carry fresh products fast. As for ships, When it is bad and they don't move, the products are not carried on schedule. (2) The need for transportation is increasing. And now, there are not enough truck drivers to carry products. It is necessary to change the system of transportation to solve the environmental problem.
