Scientists can learn about man by studying animals, such as mice, rats and monkeys. The scientists in a laboratory areexperimenting on mice and they are studying the relationship between diet and health.
In this experiment, the scientists are studying the relationship between the amount of food the mice can eat and theirhealth. The mice are in three groups. All these groups are receiving the same healthy diet. But the amount of food that eachgroup is receiving is different. The first group is eating one cup of food each day, the second two cups, and the third threecups.
After three years, the healthiest group is the one that is only eating one cup of food each day. The mice in this group arethinner than normal mice but they are more active. Most of the day, they are running, playing with one another, and using theequipment in their cages. Also, they are living longer. Mice usually live for two years, while most of the mice in this groupare still alive after three years.
The second group of mice is of normal weight. They are healthy, too. They are active, but not as active as the thinnermice. But they are only living about two years.
The last group of mice is receiving more food than the other two groups. Most of the day, these mice are eating orsleeping. They are not active.

A new came as a surprise that an elderly woman died yesterday after (21) knocked down by a motorist who had made no (22) to brake (刹车) .

What is the 'biggest city in the world? That is, (21) city has the largest population? This seems like (22) question to answer, but actually it isn't.
It's actually rather difficult to say which cities (23) the largest. There are two reasons for this difficulty. First of all, it isn't easy to determine a city's boundaries, that is, where a city ends. Nowadays, nearly all cities have a large (24) area around them. So when we talk about the population of a city, we often mean the population of the whole metropolitan area around the city. That means that it's difficult to determine what the population of a city is because it's difficult to define what a city is.
The second reason that it is difficult to 25 the population of different cities is this: it is almost impossible to get (26) about the population of all cities for the same year. For example, we might get an estimate of New York's population in 1979 and an (27) of Mexico City's population in 1981. So we real ly can't compare the numbers because the information is for (28) different years. And the population of cities changes rather quickly, especially in some cases. For example, the population of Jakarta, Indonesia, may increase by 5% each year, so the population figure will change rather quickly.
So we can say that these are our two (29) for comparing the populations of cities: one, it's difficult to determine the (30) of a city, and two, it is difficult to get accurate information.

B. which
