纵观全文结构,从首段的“In science, a theory is a reasonable explanation o f observed events thatare related.(在科学中,理 论是对所观察到的相关事件的合理解释。)”这种下 定义的写作手法来引出文章主题;到后几段作者论 述"Auseful theory, in addition to explaining p ast observations, helps to...
In science, a theory is a reasonable explanation of observed events that are related. A theory often involves an imaginary model that helps scientists picture the way an observed event could be produced. A good example of this is found in the kinetic (运动的) molecular theory, in which ...

When contributions were made by geniuses outside the club—women, or people of a different color or belief—they were unacknowledged and rejected by others. A study recently published by Science found that as young as age six, girls are less likely than boys to say that members of their ...

Additionally, Lp(a) level was conversely associated with the risk of central obesity, high fasting glucose, high triglycerides, and low HDL cholesterol, but not with hypertension. Stratified analyses suggested that increasing levels of Lp(a) was associated with decreased risk of MetS in all the ...
greatest things we can teach our children is to love learning. Learning science is a great way to do so. Childrenare intrigued byscience because much of science is hands-on. It attracts most children. Nothing makes a child sit up and take notice like the “WOW!” of a great science ...
