From my experience，there are three main reasons why people don't cook more often: ability，money，and time. 16 Money is a topic I'll save for another day.So today I want to give you some wisdom about how to make the most of the time you spend in the kitchen.Here are three tips for great cooking on a tight schedule：

One important biological factor that helps women live longer is the difference in hormones between men and women.
37 Between the ages of about 12 and 50，women produce hormones that are involved in fertility(生育能力)．These hormones also have a positive effect on the heart and the blood flow.In fact，women are less likely to have high blood pressure or to die from heart attacks.
G．Hormones are chemicals which are produced by the body to control various body functions.
But daydreamers are also responsible for some of the greatest ideas and achievements in human history. 72 Can you imagine what kind of world we would have without such ideas and inventions?
C．Without wandering minds，we wouldn't have relativity，Coke or Post-it notes.
[思路分析]选项中的relativity，Coke or Post-it notes与前句的the greatest ideas and achievements 和后句的such ideas and inventions为对应关系，而且是具体的实例，应属于例证关系。
Some people may think that a garden is no more than plants，flowers，patterns and masses of color.Others are concerned about using gardening methods that require less water and fewer fertilizers (肥料)．18 ．However，there are a number of other reasons that might explain why you want to garden.One of them comes from our earliest years.

Training for a marathon requires careful preparation and steady，gradual increases in the length of the runs.16.Before you begin your training，buy the best-fitting，best-built running shoes you can find.No one can say which brand will work best for you or feel best on your feet，so you have to rely on your experience and on the feel of each pair as you shop.When you have found shoes that seem right，walk in them for a few days to double-check the fit. 17 ．As always，you should stretch (伸展) at least ten minutes before each run to prevent injuries.
E．If they still feel good，you can begin running in them
[思路分析]根据空格后的句中的before each run可判定空格内的句子和run有关系，空格前的句子说的是“当你发现似乎合适的鞋子时，穿着走动几天，再次检查其舒适度”，然后进一步说“如果感觉舒服的话，可以开始跑步”，属于层递关系。
