The development of the modern presidency in the United States began with Andrew Jackson who swept to power in 1829 at the head of the Democratic Party and served until 1837.

两个句子的句子种类是什么？谢谢大家

Answer 1

两个句子都是主从复合句。第一句的主语：The development of the modern presidency in the United States 美国现代总统选举的发展；谓语：began （with）(从)...开始；
with Andrew Jackson who swept to power in 1829 at the head of the Democratic Party and served until 1837.介词短语，其中又含有一个定语从句who swept to power in 1829 at the head of the Democratic Party and served until 1837.
全句意为：美国现代总统选举的发展始于安德鲁·杰克逊，他于1829年成为民主党领袖而登上权力宝座直到1837年。
第二句主语：Improvements in childhood nutrition in the first quarter of the twentieth century其中的中心词是improvements， 介词短语in childhood nutrition作后置定语，介词短语 in the first quarter of the twentieth century作时间状语
for example 插入语；谓语：gave ； 间接宾语：today's elderly people ；直接宾语：a better start in life than their predecessors 其中含有than引导的比较状语从句。.
全句意为：例如，20世纪前25年里对儿童营养的改进为今天的老年人提供了一个比他们的前辈更好的生活开端。

1.主动结构。整个句子的主语是The development 整句谓语是began／ 介宾结构做补语with Andrew Jackson／ who swept to power in 1829 at the head of the Democratic Party and served until 1837.为who引导的定语从句修饰Andrew Jackson。／swept 和served是并列结构，从句中做谓语。 2主动间宾直宾结构.整句主语improvements 整句谓语gave 整句宾语间接people 整句直接宾语a better start 句子种类∶两句都是陈述句，简单句。

美国现代的总统制起于安德鲁.杰克逊，他在1829年以民主党党首身份当选为总统，任期至1837年为止。

Andrew Jackson 宾语
who swept to power in 1829 at the head of the Democratic Party and served until 1837定语从句，修饰Andrew Jackson
who定语从句的主语
swept to power 、served 定语从句的谓语
in 1829 at the head of the Democratic 和until 1837分别是修饰定语从句两个谓语的状语

Improvements in childhood nutrition in the first quarter of the twentieth century主语
in childhood nutrition in the first quarter of the twentieth century主语Improvements的定语
for example插入语
gave谓语
today's elderly people 谓语gave的间接宾语
a better start in life than their predecessors谓语gave的直接宾语

第一个句子是含有定语从句的复合句，第二个是简单句
