ex vocabulary. When they【C1】______ school, most girls have slightly better verbal skills than boys—【C2】______, they are a month or two ahead. As they progress【C3】______ primary school, girls continue to【C4】______ boys when it comes to verbal skills. By the time children leave primary school, girls are about a year【C5】______ with reading and the gap is even bigger for writing.【C6】______, it should be noted that boys are【C7】______ level with girls when it comes to attainment in maths at primary school. The gap in attainment at the age of 16 has led some teachers to believe that【C8】______ lessons in core subject are the way forward when it comes to【C9】______ male students and improving boys grades. They argue that boys,【C10】______, feel less disheartened in subjects like【C11】______ when there are no female students in the classroom to【C12】______. Others believe that girls and boys【C13】______ best when the opposite sex is taken out of the equation completely—and【C14】______ a single-sex environment, especially at【C15】______ school level. Some schools believe that a male【C16】______—whether it is a male teacher or more【C17】______ from dad at home—is a key factor in impelling boys and improving their grades. Others advocate a more boy-friendly environment at school, whether its【C18】______ more books in the library that appeal to boys or trying【C19】______ different teaching styles in lessons to【C20】______ boys in learning.

One day, drought(干旱)may be a thing of the past at least in coastal cities. Vast areas of desert throughout the world may for the first time【C1】______to life and provide millions of acres of【C2】______where now nothing grows.

By the end of this century this may not be mere【C3】______. Scientists are already looking for the【C4】______of using some of the available ice in the polar regions. In these regions there are vast ice-caps formed by snow【C5】______over the past 50,000 years. Layer【C6】______.layer of deep snow means that, when melted, the snow water would be pure, not salty【C7】______sea-ice would be. There is so much potential pure water here【C8】______it would need only a fraction of it to turn much of the desert or poorly irrigated parts of the world【C9】______rich farmland. And what useful packages it would come in! It should be【C10】______to cut off a hit of ice and transport it!

【C11】______perhaps a passing iceberg(流冰)could be captured. They are always breaking away from the main caps【C12】______around, pushed by currents, until they eventually melt and are wasted. Many icebergs are, of course, far too【C13】______to be towed any distance, and would melt before they reached a country that needed them anywhere. It would be necessary to【C14】______one that was manageable and that was big enough to provide a good supply of ice when it【C15】______us. Engineers think that an iceberg up to seven miles long and one and a half miles wide could be transported【C16】______the tug pulling it was as big as a supertanker] Even then they would【C17】______only twenty miles every day. However, once the iceberg was at its【C18】______, more than 7,000 million cubic meters of water could be【C19】______from it!

That would probably be more than enough for any medium-sized city【C20】______in the hottest summer! But no doubt use could be made for it.
