解决此题的关键是弄清句子意思。前一个分句说明，很多人得到了救济的罐装食品，句中可认为省略了表示比较的than ever（before）短语。因此此处相当于the food bank needs more（canned）food than ever（before）．
计算高手系列答案Since the beginning of history, man has been attracted by the idea of living forever, of winning the fight against death and disease. So far, this has only remained a dream. Many people have wondered whether it would be possible to find a way to preserve human bodies, and what would be the best way.
It has long been known that meat of fruit can be kept fresh for long periods by freezing; in ancient China, for example, food was stored with ice to keep it fresh. This method could also be useful for preserving humans.
However, most living beings that exist under warm conditions die when frozen. This is because of the harmful effects of freezing ice crystals(晶体), which not only are larger than the volume(体积) of the water originally in the cells, but also form sharp cutting shapes that harm the cells.
In the 1940s Dr B.J. Luyet and a group of scientists in England were working on the problem of freezing cells without damaging them. Since the harm caused by ice crystals was the main cause of damage, Luyet suggested removing some or all of the water from the cells before freezing them.
Using living cells form chicken, Luyet and his assistants discovered that they could partly dry the chicken cells, using a mixture of the white part of an egg and glycerin (丙三醇). Some success was obtained. The chicken cells were dried, frozen for a period of time, and then carefully unfrozen. Almost all the cells recovered when they reached normal temperatures.
Since then, the cooling of whole animals to a temperature far below freezing point for later unfreezing has become more of a possibility, and the glycerin method would probably be used to accomplish this. When this can be done completely and successfully, science will have moved much closer to its aim of freezing and storing incurable patients until the day they can be cured.

I know what you’re thinking: pizza（比萨饼）？ For breakfast? But the truth is that you can have last night’s leftovers in the a.m. if you want to.
学科网
I know lots of women who skip breakfast (不吃早饭), and they have a ton of different excuses for doing it. Some say they don’t have time, others think they’re “saying” calories (卡路里)，still others just don’t like breakfast food.学科But the bottom line is that eating in the morning is very important when you’re trying to lose weight .“Eating just about anything from 300 to 400 calories would be better than nothing at all,” says Katherine Brooking, R.D. , who developed the super-easy eating plan for this year’s “SELF CHALLENGE”. And even pizza can be healthy if it’s loaded with vegetables, and you stick to one small piece.学科Breakfast is one meal I never miss, and the same goes for most weight loss success stories. Research shows that eating breakfast keeps you from overeating later in the day. Researchers at the University of Southern California found that breakfast skippers have a bigger chance of gaining weight than those who regularly have a morning meal.学科网
So eat something in the morning, anything. I know plenty of friends who end up having no breakfast altogether, and have just coffee or orange juice. I say, try heating up last night’s leftovers – it may sound crazy, but if it works for you, do it! I find if I tell myself, “You can always eat it tomorrow.” I put away the leftovers instead of eating more that night. Try it … you may save yourself some pre-bedtime calories. And watch your body gain the fat-burning effects. 学科网

Every ten years there is a national census （人口普查）to count the number of people. The Census Office asks every household to answer questions on a census form.
The census counts...
● the number of people in each area
● the numbers of men and women and whether they are single, married, widowed or divorced
● how many children there are, how many teenagers, people in their twenties, thirties, forties... retired people and so on
The census counts people by...
● the kind of housing they live in
● the country in which they were born
● the kind of job they do and how they travel to work
Some uses of the census:
Housing: to work out present and future needs we must know how people are housed now, and the sizes and ages of their families.
Hospitals, schools and other local services: the size of annual grants made by the Government to these services depends largely on the numbers and needs of people in the area. Many of the figures come from the census.
Planning: the census shows how many people have moved from one area to another and how the local workforce is changing. This information is used when factories, offices, shops, public transport and places for leisure are being planned.
In strict confidence
The census is taken in order to provide figures about the nation as a whole; it does not give information about any named person, family or household.
Names and addresses are needed to take the census accurately, but they are not fed into the computer. After the census, the forms are locked away and will not be released to anyone outside the Census Office for 100 years.
The answers you give on your census form will be treated in strict confidence. NO one outside the Census Office will see your completed form. Everyone working on the census is sworn to secrecy and can be charged if he or she improperly reveals information.
