There were many beautiful buildings in ancient Rome, but the living conditions for ordinary people were bad. Most of their homes were so poorly made that they fell down or were fire hazards (danger) with their steep, narrow wooden stairways. Most people were packed into apartment buildings that rose shakily (unsafely) six to twelve floors above the ground. The apartments were rooms about three metres square, and each building housed about five hundred people.

These tall buildings faced each other across streets only three metres wide, so no sunlight reached the ground. Even so, apartments were costly, though cheaper places could be found outside Rome. But people wanted to be near their work and entertainment. So the streets became crowded and it was hard to move quickly. At night, the streets were filled with noise as food and supplies were brought into the city on wagons and carts.

1.In ancient Rome, most people lived in ________ apartments.

A.small and crowded B.clean and tidy

高二英语单项填空极难题查看答案及解析

For years , many people would not believe that smoke could attack so many parts of the body in so many ways . Study shows , however , that tobacco isn’t one single thing .  At least 60% of it is gas—20 different kinds of gas . And one of these is the deadly carbon monoxide (CO) （一氧化碳）.

In factories , the amount of this gas in the air is measured , and it must be kept under fixed , safe level . But there is 640 times this safe amount in cigarette smoke .

Oxygen is carried through your body by the red blood cells . But this poison gas , CO, will get to the blood cells before the oxygen can . So , if you smoke your blood carries five to ten times more of this deadly gas than is normal . To make up for this , your body must make more red cells .

The oxygen in your blood passes into your tissues（组织）. But here again CO makes trouble . It keeps the oxygen from passing into your tissues as fast as it should . Because of this , cigarette country is always about 8000 feet above sea level . Someone who smokes and lives at sea level gets as little oxygen as a nonsmoker at an altitude（高度）of nearly two miles .This happens to everyone who smokes , no matter how old or how young . Anyone who competes in sports can tell you that those who smoke run out of breath more quickly than those who do not .

1．The gas amount in cigarette smoke is______________.

A．640 times higher than the gas safe levels in factories

B．640 times lower than the gas safe levels in factories

C．640 times as much as that in factories

D．as dangerous as that in factories

2．If you smoke , ______________ .

A．your blood carries more oxygen than is normal

B．your blood carries much more CO than is normal

C．you can have five to ten times of blood than usual

D．your blood will be poisonous

3．Those who smoke______________.

A．all live at sea level

B．don’t live at an altitude of two miles

C．breathe as much oxygen as non-smokers

D．only get the same amount of oxygen at the sea level as non-smokers at an altitude of nearly 2 miles

高二英语单项填空简单题查看答案及解析

Have you ever wondered why there are so many skin colors in the world? Do you know why people living in particular areas usually have a certain color? Biology and history are the two reasons for this.

Skin contains something called melanin, which determines a person’s skin color. The more melanin a person has, the darker his or her skin will be. The amount of and the production of melanin are controlled by genetics, but can be affected by other things, such as sunlight. If a person lives in a place with less sunlight, a person’s body will produce less melanin, making the skin lighter.

Skin color is also affected by another source ---- vitamin D. humans all need vitamin D to build bones. People can get it by eating foods such as fish and milk, or from sunlight, so sunlight absorbed by melanin cannot be used for vitamin D production. Therefore, a dark—skinned person will produce less vitamin D than a light—skinned person when they received the same amount of sunlight.

The connection between vitamin D production and skin color is clear when we look at evolution. The earliest humans lived in Africa, their dark skin produced less vitamin D because of their dark skin. As a result, their skin made less melanin, so they could get enough sunlight to produce vitamin D. their skin gradually got lighter and they lost hair. Now, people living in areas with strong sunlight like Africa, have darker skin, while people living in other areas have lighter skin. The exception to this is the Inuit, who live in a place with little sunlight, but have dark skin because they eat a lot of fish and have enough vitamin D.

Evolution has given us a rainbow of skin colors. Humans have always had melanin to determine our skin color. What has changed through history is the environment where we have lived. This has in turn changed our melanin production, and eventually, skin color.
