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、Small-scale farmers are the major support for African agriculture.
B、The small-scale farmers produce 70-percent of the food need.
C、About 80-precent of these farms are depend on the weather.
D、There are about 90-percent small-scale farmers in sub-Saharan.

答案 A

解析 新闻开头说到气候变化对非洲农业的影响,随后便介绍了非洲农业的情况:小农户是非洲农业的支柱(the major support for African agriculture),故A正确。新闻中提到撒哈拉南部的非洲约有70%的农业人口都是小农户,他们的粮食产出占非洲所需粮食的80%,约有90%的农场是靠天吃饭,这意味要依赖于天气。B、C、D将这三项对应的数据均与新闻不符。
