如图是花生的果实,据此可判断花生属于(  )

A.藻类植物

B.蕨类植物

C.裸子植物

D.被子植物

答案

藻类植物、蕨类植物都属于孢子植物,不产生种子.裸子植物的胚珠外面无子房壁发育成果皮,种子裸露,仅仅被一鳞片覆盖起来,如松树、苏铁等.被子植物的胚珠外面有子房壁发育成果皮,胚珠发育成种子,种子包被上果皮构成果实,如花生、桃树等.从图中可以看出花生种子外面有果皮,花生油果皮和种子两部分组成,因此属于被子植物.

故选D.

Country-dwellers(农村居民) often say the constant noise, heavy traffic and crowds of the city would drive them mad. Well, they might be right, according to the latest research. City residents are more likely to develop mental illnesses than those who live in villages, a study has found.

Researchers from Cardiff university examined the lifestyles of more than 200,000 people in Sweden and found that those who lived in urban areas were more at risk from mental illnesses than people who lived in villages.

The experts don’t know exactly why this is but they suggest that town and city residents are more likely to be ostracized(排挤) by those around them. They are more likely to experience discrimination(歧视) if they do not fit in, which can lead to them feeling anxious and even developing mental illnesses.

Dr Stanley Zammit, who led the research said that people living in towns and cities are more likely to develop other mental illnesses that result in personality changes — a condition known as non-affective psychosis(非情感性精神病).

Earlier this year an official report found that village-dwellers live an average of two years longer than those living in towns and cities. According to figures from the Office of National Statistics in the UK, men who live in villages are likely to live for between 78 and 79 years, while those in towns and cities can expect to survive to an age of 76. Women on average survive to their 81st birthday in towns and cities, but live to between 82 and 83 in villages. The small marked town of Wimborne Minster in rural Dorset was named the healthiest place to live in.
