[单项选择]The right combination of bricks, mortar and plaster can be mixed to build a city, but it is the city’s people who add that extra dimension which makes it vibrant, memorable, famous and much-visited. London is such a city, and a major exhibition about its people makes this point by pulling together paintings, drawing and prints by artists over the centuries to show Londoners from all walks of life and in all manners of setting. The capital’s renowned old markets, most now gone, like Covent Garden and Billingsgate, captured the eye of painters because of the extraordinarily disparate range of characters mingling together. Processions and ceremonial events were popular subjects, although many artists were inspired by the individuals they saw: the street traders, laborers, merchants, craftsmen, society folk, servants, visiting foreigners, the very poor, the old, and the criminals.

A. the city itself

[单项选择]Atoms (原子) are all around us. They are the bricks of which everything is made. Millions of atoms are held in just one grain of salt, but in spite of their small size they are very important. The way an everyday object acts depends on what kind of atoms are in it and how they act.
For example, you know that most solid objects melt (溶化) if they get hot enough. How does it happen It is the effect of the heat on the object’s atoms. All atoms move constantly. When they are hot, they move faster.
Usually the atoms in an object hold together and give the object its shape. But if the object grows hot, its atoms move so fast that they break the force that usually holds them together. They move out of their usual places so that the object loses its shape. Then we say that the object is melting.
Atoms in an object move ______.
A. when it is heated
B. whenever it is hot
C. when it is melted
D. all the time
