A new study says the speed and severity of climate change could cause major damage to small African farms. These farmers are already struggling to deal with the effects of climate change. The study was released at the African green revolution forum in Addis Ababa. It is called the African Agriculture Status Report
Small-scale farmers are the major support for African agriculture. About 70-percent of the rural populations in sub-Saharan Africa are small-scale farmers. They produce about 80-percent of the food need in Africa
About 90-precent of these farms are rain-fed, which means that they depend on the weather. Weather is rainfall. Weather is drought. Weather is an increase in temperature. They are more exposed to these climate effects than any other part of the world. On top of that most of them use their own labor or family labor. They are not mechanized.
The report says farmers in sub-Saharan Africa are also dealing with rising temperatures. This major rise in temperature brings a lot of issues to Africa food security. It is going to affect reduction in yield, increase invulnerability to harmful insects and diseases that will kill most of the domestic animals.
5. What will cause serious damage to small African farms?
6. What do we learn about African agriculture from the news report?
7. What will rising temperatures affect the farmers’ life?
选项
A、It will affect increase in yield.
B、It will kill most of the domestic animals.
C、It will reduce many harmful insects.
D、It will affect food security.
答案
B
解析
新闻末尾提到,气温的大幅度升高会使家畜更容易受到害虫和疾病的困扰,导致大多数牲畜死亡,故B正确。气温的大幅度升高将给非洲粮食安全带来很多问题,将导致产量降低,A“它会导致产量增高”与新闻内容相反。气温的大幅度升高会增多虫害,而不会“减少害虫”,故C错误。D“会影响食品安全”未在新闻中提到。
