A. B. C. D.
D
People love to wear clothes made from cotton because of its breathable comfort. When you enjoy the benefits (好处) it brings, do you know where it comes from The Indus Valley Civilization (印度河流域文明) is believed to have harvested (收获) cotton for the first time, but China is now the world’s second-largest cotton producer. Xinjiang in the northwest of China is home to the nation’s largest cotton-producing area.
In early September every year, the white hair that grows inside the cotton boll (棉桃). stretches out for more sunlight, as if telling farmers it’s ready to be picked. Harvesting lasts from early September to late October. China produces about 22% of the world’s cotton, of which 87.3% comes from Xinjiang, according to the latest data from the National Bureau of Statistics.
The planting of cotton in Xinjiang dates back to the late Western Han Dynasty. According to historical records, the cotton introduced from West Asia to Xinjiang was the Levant cotton. Cotton soon spread in Xinjiang because of the region’s full sunlight and moderate rainfall, which the plant needs.
Xinjiang is famous for its long-staple cotton (长绒棉), which is popular among customers. In the past, people mainly picked the cotton by hand, but now machines have gradually replaced it. In Xinjiang, nearly 70% of cotton is harvested mechanically (机械化地). The use of machines prevents (防止) the cotton from being polluted and improves its quality (质量).
After bags of cotton are packed and transported to many factories, they become clothes, toys, and others that we see in daily life. Cotton’s versatility (多功能性) has earned it a nickname — “white gold”.

4．【解答】解：由电路图可知，甲、乙两导体并联，
因并联电路中各支路两端的电压相等，
所以，甲、乙两端的电压U甲＝U乙；
由于甲、乙两个导体材料和长度相同、横截面积不同，S甲＜S乙，
则根据材料和长度相同时导体的电阻与横截面积成反比可知R甲＞R乙，
根据I可知，I甲＜I乙。
故答案为：小于；等于。
