[不定项选择题]共用题干
Step Back in Time Do you know that we live a lot longer now than the people who were born before us?One hundred years ago the average woman lived to be 45 .But now,she can live until at least 80. One of the main reasons for people living longer is that we know how to look after ourselves better. We know which foods are good for US and what we have to eat to make sure our bodies get all the healthy things they need.We know why we sometimes get ill and what to do to get better a-gain .And we know how important it is to do lots of exercise to keep our hearts beating healthily. But in order that we don't slip back into bad habits,let's have a look at what life was like 100 years ago. Families had between 15 and 20 children,although many babies didn't live long. Children suffered from lots of diseases, especially rickets (佝偻病）and scurvy（坏血病）,which are both caused by bad diets.This is because many families were very poor and not able to feed their chil-dren well. Really poor families who lived in crowded cities like London and Manchester often slept standing up,bending over a piece of string,because there was no room for them to lie down. People didn't have fridges until the 1920s.They kept fresh food cold by storing it on window-sills（窗台板）,blocks of ice , or even burying it in the garden. Some children had to start work at the age of seven or eight to earn money for their parents. If you had lived 100 years ago, you might well be selling matchsticks（火柴杆）(a job done by many children) or working with your dad by now.
People in the past preferred standing up to lying down when sleeping.

[单项选择]The food you eat does more than provide energy. It can have a dramatic effect on your body’s ability to fight off heart disease, cancer, diabetes, high blood pressure, stroke, and weak bones. With remarkable consistency, recent research has found that a diet high in plant-based foods—fruits, vegetables, dried peas and beans, grains, and starchy staples such as potatoes—is the body’s best weapon in thwarting many health-related problems. These foods work against so many diseases that the same healthy ingredients you might use to protect your heart or ward off cancer will also benefit your intestinal tract and bones.
