剑桥雅思11 Test4 Section4听力答案解析
第31题答案：dry
对应原文：But erosion can occur if soil is dry
答案解析：听到erosion意识到答案即将到来，从题干可以推断出空上应该填一个形容词，由此确定答案为dry。
第32题答案：hard
对应原文：Lal was studying soils in Africa so devoid of organic matter that the ground had become extremely hard
答案解析：听到Africa意识到的答案即将到来，与上一题类似，空上仍然要填一个形容词，由此确定答案为hard。需要注意的是，雅思听力中由于发音特点的问题，部分可能同学可能会混淆hard和hot，这时候可以根据场景辅助判断一下。
第33题答案：sugar/sugars
对应原文： Plants absorb CO2 from the air and transform it into sugars and other carbon-based substances
答案解析：听到absorb CO2意识到答案即将到来。本体采用语序颠倒的手法，将本来位于空前的substances放在了空后，不过sugars本身读的就很重，还是不太容易漏掉的。
第34题答案：roots
对应原文：While a proportion of these carbon products remain in the plant, some transfer from the roots to fungi and soil microbes, which store the carbon in the soil.
答案解析：听到while意识到上一题结束，来到34题。moves与transfer同义替换，from则原词出现，根据修饰关系确定答案为roots。
第35题答案：moist/damp/wet
对应原文：Some growers have already started using an approach known as regenerative agriculture. This aims to boost the fertility of soil and keep it moist through established practices.
答案解析：这道题与上一题相距太远，需要大家仅仅盯住小标题regenerative agriculture以防错过。fertile与fertility同义替换，根据并列关系，确定moist为答案。
第36题答案：variety
对应原文：These include keeping fields planted all year round, and increasing the variety of plants being grown.
答案解析：听到all year round定位答案即将到来。increasing原词出现，根据修饰关系，很容易确定variety为答案。
第37题答案：cattle
对应原文：Soil scientist Whendee Silver of the University of California, Berkeley, is conducting a first-of-its-kind study on a large cattle farm in the state.
答案解析：大部分这道题做错的同学都是因为cattle的拼写，题目本身没有任何难度。
第38题答案：gardens/gardening
对应原文：both agricultural, including manure and cornstalks, and waste produced in gardens, such as leaves, branches, and lawn trimmings.
答案解析：并列的常见考法。在agriculture之后加入起说明作用的句子或者列举的词汇，然后再说与其并列的garden，注意一下这种策略就好。
第39题答案：grasses
对应原文：Jones and 12 farmers are working to build up soil carbon by cultivating grasses that stay green all year round
答案解析：听到soil carbon意识到答案即将到来。虽然cultivate与using对应，但大多数同学可能反应不过来。这道题还是根据停顿与重读，先锁定grasses，然后再根据后面的all year round确定它为答案比较简单一些。
第40题答案：payment/payments/money
对应原文：Rattan Lal argues that farmers should receive payment not just for the corn or beef they produce, but also for the carbon they can store in their soil.
答案解析：听到farmers意识到答案即将到来。giving与receive同义替换，再加上payment重读，由此确定它为答案。
