Not enough fields to plant rice, wheat, vegetables, etc. Maybe caused by urban expansion, desertification, land being built into houses or factories lack of technology /læk/ 缺乏技术 Not having enough modern tools, machines, skills or knowledge to do something effectively. sandstorms water shortage farmland shortage lack of technology Rank the following problems from 1 to 4, with 1 being the worst. Give your reasons. 2a lack of technology sandstorms water shortage farmland shortage 1 3 2 4 Give your reasons. Water is the most basic need for all living things, including people, animals, and crops. Without enough clean water, people cannot drink or cook, crops will die, and daily life will stop. This problem directly threatens human survival, so it is the most serious. Water shortage (Rank 1) Give your reasons. Farmland is where we grow food. If there is not enough farmland, we cannot produce enough food for everyone. Food shortages can lead to hunger and social problems. Farmland shortage (Rank 2) Sandstorms can damage houses, pollute the air, and make it hard to breathe. They can also destroy crops and make farmland worse. However, they are usually seasonal or regional problems, and their impact is not as constant or common as water or farmland shortages. Sandstorms (Rank 3) Give your reasons. A lack of technology makes solving the other three problems harder, it is not a direct threat to survival itself. Compared to the other three problems, its effects are more indirect and can be improved over time. Lack of technology (Rank 4) Give your reasons. 一、用括号内所给词的适当形式填空 1.Lucy used ________ (be) nervous about exams all the time. 2.[江苏淮安中考] Last week，we ________ (watch) a fashion show in the school hall. 3.
