同学们好。
本周我们看一道高考真题，来自于2017年全国Ⅰ卷的语法填空。
原题这里不再贴出，任何搜索引擎都能找到。
老规矩，剔除对做题无用的废话，我们将这道题拆成单句填空，如下：
This trend, which was started by the medical community(医学界) 61______ a method of fighting heart disease, has had some unintended side 62______ (effect) .
They are required 63______ (process) the food that we eat.
When fat and salt 64______(remove) from food, the food tastes as if is missing something.
As 65______result, people will eat more food to try to make up for that something missing.
Even 66______ (bad), the amount of fast food that people eat goes up.
Fast food 67______ (be) full of fat and salt.
by 68______ (eat) more fast food people will get more salt and fat than they need in their diet.
be 69______ (care) not to go to extremes.
it is possible to have too much of both, 70______ is not good for the health.
不少高三的同学想必已经入手了全国卷真题集，不知道同学们有没有认真看过这道题的答案解析？
我翻了几个版本的真题集，也看了下网上关于这道题的解析，真是应了天下文章一大抄这句老话，各种所谓的超详细解析，连谬误都一模一样，生硬地凑答案都能原谅，但瞎说一气就让人郁闷了。脑子里得有多少浆糊，才能写出这种不靠谱的解析！
而这，其实也是我做每周一题的初衷。对网上已有的答案解析进行简单的复制粘贴，这么干，除了浪费学生时间，没有任何意义！
言归正传，看题。
This trend, which was started by the medical community(医学界) 61______ a method of fighting heart disease, has had some unintended side 62______ (effect) such as overweight and heart disease-the very thing the medical community was trying to fight. 这句较长，逗号之间是个定语从句，做插入语，第一个空就没有提示词，必填虚词。
将定语从句还原：This trend was started by the medical community(医学界) 61______ a method of fighting heart disease. 我们看到，by the medical community(医学界)是被动语态中动作的发出者，忽略即可，主谓结构完整，61空后的部分必做状语，译为一种治疗心脏病的方式，那么61空填引导方式状语的连接词，as最合适。因此61空答案为as.
砍掉插入语，剔除干扰部分，句子恢复如下：This trend has had some unintended side 62______ (effect). 主语this trend，谓语has had，宾语some unintended side 62______ (effect)。我们知道，some后面必跟名词，side effect是可数名词单数，译为副作用，因此第62空答案为effects.
They are required 63______ (process) the food that we eat. 本句中，are required是谓语动词，则其他地方的动词就是非谓语动词了，They are required后面跟目的状语表示被要求怎么做，to do形式的非谓语动词表目的，因此第63空答案为to process.
When fat and salt 64______(remove) from food, the food tastes as if is missing something. 本句主句完整，when后引导时间状语从句，此从句中，fat and salt这两样东西做主语，remove from是谓语动词，脂肪和盐只能被去除，加上本句说的是一种客观事实，本空需填一般现在时的被动语态。因此第64空答案为are removed.
As 65______result, people will eat more food to try to make up for that something missing. 空处无提示词，填虚词，as a result为表结果的固定搭配，做状语，因此第65空答案为a.
Even 66______ (bad), the amount of fast food that people eat goes up. 本句逗号后为主句，结构完整，goes up上升表递进，even程度副词后跟badly的比较级形式。因此第66空答案为worse.
Fast food 67______ (be) full of fat and salt. 本句为主系表结构，fast food是不可数名词做主语，描述一种现象，用一般现在时，因此第67空答案为is.
by 68______ (eat) more fast food people will get more salt and fat than they need in their diet. 本句中people will get more salt and fat than they need in their diet结构完整，by为介词，后面跟名词做宾语，第68空需填动词eat的名词形式。因此第68空答案为eating.
be 69______ (care) not to go to extremes. 本句为祈使句，系动词be后应跟形容词形式做表语。因此第69空答案为careful.
it is possible to have too much of both, 70______ is not good for the health. 本句中it是形式主语，将此句恢复原状后为：to have too much of both is possible, 70______ is not good for the health. 第70空无提示词，做后面句子的主语，只能填代词，先行词为逗号前的完整句子。因此第70空答案为非限制性定语从句引导词which.
总结：相比2017年Ⅱ卷的语法填空，本题难度略有上升，尤其是因为第61空中的插入语，导致句子变长。遇到这类题，同学们可先忽略插入语，从后面句子着手分析空前空后特点，搞定了第62题，再回头解决第61空。
语法填空这个题型，没必要非要完全看懂文章，同学们大可不必拘泥于出题顺序，把这种题型当成单句填空来做，会容易很多。
