9. Read the text and do the tasks after it:
STARS AND STRIPES
The Stars and Stripes. Old Glory. This is what the Americans call their national flag. There are 50 white five pointed stars on the flag, representing 50 states of the USA. It consists of thirteen horizontal stripes alternately red and white. The number of the stripes symbolizes 13 colonies that signed the Declaration of Independence on July 4, 1776 and established the United States.
Flags or banners in national colours are used on festive occasions and solemn occasions, when discovering the unknown; in wars they provide soldiers with strength and faith, in peace they become a motivation for sports competitions. American people, maybe because they come from different nations and nationalities of the world, worship their flag.
The Stars and Stripes is waving over the Capitol in Washington, D.C. and over its counterparts in all the capitals of the USA, in some places the flag is hoisted with solemnity when the sun rises and lowered with the sunset. People use the flag to decorate their houses on all kinds of holidays including Halloween. The flag is officially presented at football games even if two American teams play. There are American flags outside shopping centers and supermarkets, over gas stations, in all national parks. They are a proud symbol in American banks. Of course even more important is Old Glory abroad, there it should symbolize success of the last Great Power.

Пожалуйста помогите как читается этот текст по русски произношение например two-ту и так далее буду очень благодарна The United Kingdom (or Great Britain) is situated on the British Isles. The British Isles consist of two large islands, Great Britain and Ireland, and about five thousand small islands. Their total area is over 244,000 square kilometres.
The United Kingdom is made up of four countries: England, Wales, Scotland (on the island of Great Britain), and Northern Ireland (on the island of Ireland). Their capitals are London, Cardiff, Edinburgh, and Belfast respectively. The capital of the UK is London.
The British Isles are separated from the European continent by the North Sea and the English Channel. The western coast of Great Britain is washed by the Atlantic Ocean and the Irish Sea.
The surface of the British Isles varies very much. The north of Scotland is mountainous and is called the Highlands, while the south, which has beautiful valleys and plains, is called the Lowlands. The north and west of England are mountainous, but all the rest — east, centre, and south-east — is a vast plain. Mountains are not very high. Ben Nevis in Scotland is the highest mountain (1,343 m).
There are a lot of rivers in Great Britain, but they are not very long. The Severn is the longest river, while the Thames is the deepest one.
The mountains, the Atlantic Ocean, and the warm waters of Gulf Stream influence on the climate of the British Isles. It is mild the whole year round.
