Before then, the only transport links between Mombasa (Kenya’s main port) and Nairobi (Kenya’s capital) were rough roads and an old railway line built in 1901. The old trains were very slow. It took 10 hours to get to Nairobi from Mombasa by train. However, the new railway, built with China’s help, has already cut the travel time between Mombasa and Nairobi to about four hours for passengers. Now, more than two million people use it every year. Local Kenyans have benefited a lot from the new railway. It helps local people make more money, makes business trips easy, and transports fresh food quickly to supermarkets. This railway shows China and Kenya can work together well. Judge True (T) or False (F). ( ) 1. The new railway is 408 kilometres long. ( ) 2. People spent 10 hours taking the old train between the two cities. ( ) 3. Fewer than two million people take the new train every year. ( ) 4. The new railway was built with help from China. ( ) 5. The railway only helps businessmen in Kenya. Passage B China helps many other countries build railways, roads and hospitals. These projects change people’s lives for the better. Let’s take another railway in Africa for example. It connects two big cities in Tanzania. Before the railway, farmers could not send their fruit and vegetables to big cities fast, so lots of food went bad. Now the fast train carries food in only three hours, so farmers make more money, and city people can buy cheap fresh farm food. Besides transport, China also shares farming skills, medical knowledge with other countries. Working together makes the whole world warmer and better. Choose the best answer. ( ) 1. What is the main idea of Paragraph 1? A. China helps other countries build transport projects. B. The old transport in Africa was great. C. Farmers in Tanzania don’t grow vegetables. D. Trains in Tanzania are very expensive. ( ) 2. What was the problem before the new railway in Tanzania? A. Farmers had no food to sell. B. Farm food went bad on the way to cities. C. No one wanted to buy fresh fruit. D. The train took too little time. ( ) 3. Which of the following is NOT China’s help to other countries? A. Building railways. B. Sharing medical skills. C. Selling expensive cars. D. Teaching farming ways. 六、短文填词（用括号内词适当形式填空，每空 1 分，共 10 分） Read the passage and fill in the blanks. The Mombasa–Nairobi railway 1.________ (open) in 2017.
