這是一篇說明文,主要講述了人們日常活動中所需要的能量以及一些食物的具體能量占比。

1細節(jié)理解題。根據(jù)表格內容Woman 1,800Farmer 3,600可知,農民每天需要3600卡路里的能量,婦女每天需要1800卡路里的能量,所以婦女每天需要的卡路里是農民的一半。故選C

2細節(jié)理解題。根據(jù)圖中所示可知,牛奶中碳水化合物占比40%;米飯中碳水化合物占比85%;花生中碳水化合物占比10%;根據(jù)Carbohydrate provides 3.8 cal/gm (calories per gram) of energy.可知,碳水化合物可以提供卡路里,所以碳水化合物占比越高,提供的能量也就越多;米飯中的碳水化合物占比最高,可以提供最多的能量。故選B。

【題目】

Basketball fans around the world are mourning the death of American superstar Kobe Bryant.

Bryant was killed in a helicopter crash on Sunday in California, along with his 13-year-old daughter Gianna and seven other people. He was 41 years old.

Bryant was an 18-time All-Star player. He won five NBA championships and two Olympic gold medals. He was widely considered one of the greatest basketball players of his generation during his 20-year career with the Los Angeles Lakers.

The helicopter carrying Bryant and the others crashed into a hilly area in foggy conditions outside Los Angeles. Bryant lived south of Los Angeles and often used helicopters to travel around the area to save time and avoid Southern California traffic.

The cause of the crash is under investigation. It took place about 32 kilometers from Bryant's Mamba Sports Academy, a basketball training center in Newbury Park, California. Bryant was on his way to attend a youth basketball competition on Sunday with his daughter. Bryant and his wife, Vanessa, had four daughters.

When he retired from the NBA in 2016, Bryant was the third-leading scorer in NBA history with 33,643 points. He is widely expected to be elected to the Naismith Memorial Basketball Hall of Fame this year.

The basketball world and the Los Angeles community reacted to Bryant's death with an outpouring of sadness, disbelief and support.

In a statement, NBA Commissioner Adam Silver said Bryant was one of the greatest stars in the game. But he added, He will be remembered most for inspiring people around the world to pick up a basketball and compete to the very best of their ability.
