the sahara desert is in the north of africa between mountains, the sea and a very long river called the nile. (пустыня  сахара  на севере  африки,  между гор,  моря и    длинная реканазывается  нил.)

during the year lots of people from all over the world visit the sahara desert. they come in groups in big cars. they all have cameras and take lots of photos.(в течение года  множество  людей со всего  мира посещают  пустыне сахара.они приходят  в группы  в больших  автомобилях.  все они имеют  камер и  взятьмного фотографий.)

the nobel prizes are annual international awards bestowed by scandinavian committees in recognition of cultural and scientific advances. they were established by the swedish chemist alfred nobel, the inventor of  dynamite. the prizes in physics, chemistry, psychology or medicine, literature and peace efforts were first awarded in 1901. the sveriges riksbank prize in economic sciences in memory of nobel was instituted in 1968. although this is not technically a nobel prize, its announcements and presentations are made along with other prizes. each nobel prize is widely regarded as the most prestigious  award in its field. each laureate is presented with a gold medal, a diploma and a sum of money which depends on the nobel foundation’s income that year. the prize cannot be awarded posthumously ,  nor may a prize be shared among more than three  people.
