In epigenetic processes，chemicals influence the activity of our genes, for example in creating our internal ____.
定位词：create, internal
文中对应第七段第二句：These reactions influence how our genetic code is expressed: how each gene is strengthened or weakened, even turned on or off, to build our bones, brains and all the other parts of our bodies.
题干说“在表观遗传过程中，化学反应会影响我们的基因活动行为，例如在创造我们内部____的时候”。本题的出题位置与上一题来自同一句话，在原文中的出处也极为接近。从阅读理解的角度来看，考生应该具备internal (内部的)、organs(器官)这样的基础词汇，从而看出原文中的parts of our bodies正是对应internal organs这一表述，因此答案为B选项: organs。

Local gulls and migrating arctic terns behave in the same way when offered food.
生词： Local gulls本地海鸥
arctic terns北极燕鸥
herring 鲱鱼;鲱鱼肉
corridor（尤指两边是房间的）走廊，通道，过道
passageway过道，走廊
bottleneck狭窄路段，瓶颈路段；交通阻塞点
plains 朴素的；不加修饰的；简单的

文中对应第二段前两句：An arctic tern, on its 20,000 km fight from the extreme south of South America to the Arctic circle, will take no notice of a nice smelly herring offered from a bird-watcher’s boat along the way. While local gulls will dive voraciously for such handouts, the tern flies on.
考生即使在原文两句中有着不止一个并不认识的单词，其实也不影响对此题的解答。local gulls会为了herring这样的handouts而voraciously俯冲下来，然而arctic tern却会继续飞行，显然二者在面对食物时表现得并不一样，与题千信息相悖，因此答案为FALSE。

错题二

Very few experts agree that the movement of aphids can be considered migration.
答案： NG

译文：很少有专家赞同蚜虫的移动可以被视为迁徙。

定位词：very few experts agree, movement of aphids
第四段前两句：But daily vertical movements by zooplankton in the ocean-upward by night to seek food, downward by day to escape predators- can also be considered migration. So can the movement of aphids when…
本题具有一定的迷惑性。“蚜虫移动”这个信息不难定位，原文也以事实陈述的口吻指出:浮游生物和蚜虫的移动确实可以被视为某种形式的迁徙。但此题是一道典型的“将事实与观点相混淆”思路的判断题，题干说“很少有专家认同这个看法”，是明确的“专家观点表达”，与原文的“事实陈述”既不能说是矛盾，也不能说是一致，而是NOT GIVEN。

错题三

According to Dingle, migratory routes are likely to ____
答案： G. follow a straight line.

定位词：Dingle, migratory routes, likely to
文中对应第一段第四、五句：The biologist Hugh Dingle has identified five characteristics that apply, in varying degrees and combinations, to all migrations.They are… they tend to be linear, not zigzaggy; …
题干说“按照Dingle的说法，迁徙的路线往往会”。回到原文中Dingle这个人名不难找到，route(路线)这个意思却是通过linear和zigzaggy这两个用以描述“路线”是平直还是 曲折的形容词来间接表达的，需要考生认识其中至少一个才能更准确定位。而一旦定位之后确定答案则很容易，为G项: follow a straight line (沿着一条直线 )。

题号：20
定位词：prepare for, likely to
文中对应第一段第五句：…; they involve special behaviours concerning preparation (such as overfeeding and arrival;

错题四

One problem is the construction of new homes in a narrow ____ of land on the pronghorns’ route.
答案： corridor | passageway
定位词：problem, construction of new homes, narrow
文中对应第六段倒数第二句：At one of the bottlenecks, forested hills rise to form a V, leaving a corridor of open ground only
about 150 metres wide, filled with private homes.
题干说“问题之一来自叉角羚迁徙路线上一条狭长_____上的新建房屋”。本题的难度来自于使用了narrow 来同义替换“只有150米宽”这一具体的细节信息，可能会给一些考生的定位造成一定障碍。而一旦成功定位即可得出答案为corridor。
