In many countries, the textbooks in universities are in English. Many university classes are taught in English even though the native language is not English. English is the language of international communication. It is the language of international business, research, and science. More than three-fourths of the world's mail is written in English. More than half of the scientific research journals are in English. Most other languages have borrowed many English words. Why did English become the international language? In the middle of the nineteenth century, French was the international language. The Britain became very powerful in the world. England started colonies in North America and India in the seventeenth century. By 1900 England also had colonies in other parts of Asia, Africa and the South Pacific. The people in the colonies had to use English. Slowly it became more important than French internationally. After the Second World War, the United States became very powerful, and even more people began to learn English. Is English a good international language? It has more words than any other language.

Q: Read the following article and select the best answer. Article: Most people, when they travel to space, would like to stay in orbit for a few days of more. And this stands to reason, if you' re paying $20,000 for your trip to orbit! Strain order for tourism to reach its full potential there' s going to be a need for orbital accommodation--or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel--private rooms, meals, bars. But they' ll also offer two unique experiences: impressive views--of Earth and space--and the endless entertainment of living in zero gravity--including sports and other activities that make use of this. The hotels themselves will vary greatly--from being quite simple in the early days to huge luxury structure at a later date. It s actually surprising that as later as 1997, very few designs for space hotels were published. This is mainly because those who might be expected to design them haven' t expected launch costs to come down far enough to make them possible. Lots of people who' ve been to space have described vividly what it' s like to live in zero gravity. There are obviously all sort of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don' t need to sleep much living in zero gravity, so you' ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below. Of course all good things have come to an end. Unfortunately, and so after a few days you' ll find yourself heading back enough you' ll be much more expert at exercising in zero gravity than you were when you arrived. You' ll be thinking how soon you can save up enough to get back up again--or maybe you should change jobs to get to work in an orbiting hotel. Question: Which of the following i s NOT discussed in the passage? - When was the space traveling made possible? - What are the unique experiences that space hotels will offer? - Why were there not many published designs for space hotels? - How can the travelers enjoy themselves in space hotels?
A: When was the space traveling made possible?

Read the following article and select the best answer. Article: The creative projects of World Food Program (WFP) focused on preventing hunger from taking hold in the future and breaking the cycle of hunger. Here are some of the ways in which we work to prevent hunger in the future: School Meals As well as directly addressing hunger, School Meals projects encourage families to keep their children in school and help them build better futures. If children aren't hungry they will concentrate on their lessons. With a solid education growing children have a better chance of finding their own way out of hunger. These projects benefit girls especially. For more information: www.wfp.org/schools meals. Food for Assets WFP's Food for Assets projects provide the hungry with food to lay the foundation for a better tomorrow. When poor farmers no longer have to worry about the next meal, they have the time and energy to build irrigation systems that can increase production. Similarly, Food for Training projects allow the poor to devote time to learning skills that will sustain them economically in the future. For more information: www.wfp.org/food-assets. HIV/AIDS WFP uses its food rations to reduce the blow of HIV and AIDS. The agency distributes its rations to people living with HIV and AIDS, so they can keep providing for their families for longer and have time to transfer vital knowledge and skills to the growing number of AIDS children--the next generation of food providers in developing countries. For more information: www.wfp.org/hiv-aids. Purchase for Progress WFP buys large amounts of food in developing countries. It has this purchasing power and uses it to help poor farmers contact reliable markets where they can get competitive prices for their produce. With secure markets, farmers will be encouraged to produce more and innovate .The knock-on effect is producing more food for everyone. For more information: www.wfp.ofp/purchase-progress.
