Определите пословицу, которая соответствует основной мысли легенды о древнегреческом философе Сократе: Однажды к Сократу привели мужчину и попросили высказать о нём своё мнение. Мужчина молчал. Сократ долго смотрел на него, а потом воскликнул: «Да заговори же ты наконец, чтобы я мог тебя узнать!»

Charity begins at home
It is said that charity begins at home, and people in the UK seem to have put these words into practice. Their
enthusiasm for helping others shows in the 187,000 charity organisations that exist in the country. Some of the
most famous ones are Oxfam, Age Concern, the RSPCA, the British Heart Foundation and Marie Curie Cancer
Care.
People donate money to charity organisations or volunteer to help them raise money. Many of these
organisations run charity shops. The first charity shop in the United Kingdom was established by Oxfam in Broad
Street, Oxford. Oxfam has the largest number of charity shops in the UK with over 800 stores.
Charity shops sell goods at very low prices. The items for sale are usually second-hand and donated by members
of the public. These include books, records, CDs, clothes, accessories, household items, furniture and costumes
for special occasions such as Halloween. There are bargains for everyone! Some charity shops also sell new
goods that are somehow related to the cause they support. In Oxfam stores, for example, you can find fair trade
food and crafts.
The staff who work at charity shops are volunteers, so most of the profits from the sales go towards the charity.
In the US, where charity shops are called thrift stores, this kind of shopping is so popular that it has got it's own
word, it's called thrifting.
