能力提升
Ⅰ．【语篇解读】 本文是一篇说明文。文章主要介绍了虎鲸母子间的依赖关系及其对繁殖的影响。
1．D [主旨大意题。根据全文内容，结合第一段“Killer whales are mama's boys...who gives up having additional children to look after her boy，according to a new study．”和第三段中“Weiss wanted to know whether these children came at a cost — particularly，whether they hurt a mother's fertility．”可知，文章主要介绍了虎鲸母子间的依赖关系及其对繁殖的影响。]
2．B [细节理解题。根据第四段“In a given year，mothers of sons were less than half as likely to have another baby as childless females or mothers of daughters．Noticeably，both a 3 year old son and an 18 year old son lowered their mom's chances of having more children，Weiss says．”可知，当母鲸有儿子时，她生更多孩子的可能性明显会下降。]
3．C [推理判断题。根据倒数第二段“The researchers suggest mom's favoritism toward her boys developed because of the particular social structure of these pods...he mates with females in passing pods who then go on to raise children in their own social units．”可推知，母亲偏爱儿子的原因之一是为了节约食物，减少群体内的竞争。]
4．A [推理判断题。根据最后一段中“Weiss says he hopes to do more research in different species of whales．But now，killer whales remain an extreme example of parental care across the animal kingdom．‘In other animals，’he says，‘at some point，you just stop depending on your mom as much．’”可推知，Weiss认为虎鲸这种母子关系在自然中并不常见。]
Ⅱ．【语篇解读】 本文是一篇说明文。文章介绍了能量的来源和作用，以及植物、动物和人类如何获取和利用能量。
1．G [上文“Energy can come in many different forms．”提到能源有多种形式，G项“例如，光能、热能和化学能都是不同形式的能源”举例说明能源有哪些形式，上下文语意连贯。]
2．E [下文“This chemical process is called photosynthesis．”提出光合作用的概念，根据句中“This chemical process”可知，上文会讲到光合作用。E项“它们利用太阳的能量将水和二氧化碳转化为植物的食物和氧气”正是光合作用的过程，且句中“the sun's energy”照应上文中“Plants absorb sunlight”。]
3．B [下文“Then，a human eats the rabbit．”中“the rabbit”是特指，可推知设空句中会提到兔子，B项“那种植物可能会被兔子吃掉，给兔子提供能量”中提到下文中出现的兔子，且与上下文衔接连贯。]
4．A [下文“We require energy from food for basic functions，like moving and breathing．Energy from food also helps our body repair itself and stay warm．”指出从食物中获取能量的作用，A项“这种反应产生的能量为我们的身体提供能量”符合语境。且A项中的“this reaction”照应上文中“a chemical reaction takes place”。]
5．F [下文“Wholefoods...Wholefoods can provide us with enough energy over long periods of time．”举例说明了不同食物中的不同营养物质，F项“我们从食物中获得的能量值取决于我们吃的食物中含有哪些营养物质”引出下文。]
Ⅲ．【语篇解读】 本文是一篇记叙文。文章主要讲述一只叫Paley的猫救了一个女人的英勇故事。
1．C [根据上文“who does some brave act(做出某种英勇的行为)”以及下文内容可知，Paley救了一个女人，故选C。]
2．A [根据下文“the homeless cat”可知，Paley无家可归，她们想为他建一个家，故选A。]
3．B [根据下文“he continued to sleep anywhere he liked”可知，Paley继续睡在他喜欢的地方，说明他对于她们建的家不感兴趣。]
4．D [根据下文“They made sure he could keep warm in the cold winter nights．”可知，她们轮流照顾Paley。]
5．B [根据下文“as they were keeping their own cats as well”可知，她们有养猫的经验。]
6．A [根据上文她们照顾Paley以及空后“with the kind women”可知，Paley开始对她们感到自在。]
7．C [根据下文“and would even sit on their legs”可知，Paley愿意让她们抚摸自己。]
8．D [根据下文“refused to reply to Jean when she called him like before”可知，Paley不像以前一样，故行为奇怪。]
9．A [根据下文“refused to reply to Jean when she called him like before”可知，Paley很反常。]
10．C [结合上文提到Paley很反常可知，事情有些不正常。]
11．B [根据下文“so she walked after him”可知，猫想让Jean跟着他。]
12．A [根据下文“She didn't reply when Jean called her．”可知，她不回应，说明她无意识，故是躺在雪地里。]
13．D [根据下文“She quickly called the police and cared for her．”可知，Jean知道该怎么做。]
14．B [根据下文“the woman was fine in the end”可知，这是一件幸运的事。]
15．C [根据第一段中提到的“hero”和下文“and even pets and animals can be heroic”可知，此处呼应第一段中的hero。]
Ⅳ．【语篇解读】 本文是一篇说明文。文章主要讲述了昆虫在未来可能会成为饭桌上一道常见的菜。
1．have become [考查动词时态和主谓一致。此处insects为主语，为复数，时间状语为in the past decades，应用现在完成时，故填have become。]
2．to [考查介词。此处为固定短语be harmful to，意为“对……有害”，故填to。]
3．Experts [考查名词复数。此处主语expert“专家”为可数名词，且根据谓语动词say可知，主语应为复数；位于句首，首字母大写，故填Experts。]
4．why [考查定语从句。此处引导定语从句，在从句中作原因状语，先行词为reason，故填why。]
5．rapidly [考查副词。此处应用副词修饰谓语动词，故填rapidly。]
6．to be [考查非谓语动词。此处为be expected to do sth，意为“预计做某事”，故填to be。]
7．made [考查非谓语动词。此处为meals的定语，且meals与make之间为被动关系，故应用过去分词短语作后置定语，故填made。]
8．where [考查定语从句。此处引导定语从句，在从句中作地点状语，先行词为stores，故填where。]
9．excited [考查形容词。此空作表语，修饰人，应用 ed结尾的形容词，故填excited。]
10．An [考查冠词。此处farmer“农民”为可数名词，且此处泛指“一个农民”，insect发音以元音音素开头，因此用不定冠词an；位于句首，首字母大写，故填An。]

Ⅰ．阅读理解(共4小题；每小题2．5分，满分10分)
Killer whales are mama's boys．A son will follow his mother，taking bits of fish and other food，throughout his life，even as his sisters grow up and have babies of their own．This neediness comes at a significant cost to mom，who gives up having additional children to look after her boy，according to a new study．
Michael Weiss has observed the mother son bond(纽带) in killer whale groups off the Pacific coast of North America．These animals live for tens of years，yet even fully grown males “act like little kids around their mom，swimming right beside her like they're still babies”．
Weiss wanted to know whether these children came at a cost—particularly，whether they hurt a mother's fertility(生育能力)．He and his team studied 40 years' worth of data on three Pacific pods(小群动物)．Sure enough，the team found a “huge effect”．
In a given year，mothers of sons were less than half as likely to have another baby as childless females or mothers of daughters．Noticeably，both a 3 year old son and an 18 year old son lowered their mom's chances of having more children，Weiss says．
The researchers suggest mom's favoritism toward her boys developed because of the particular social structure of these pods．When a daughter gives birth，her babies stay in the same group and therefore compete with the rest for food and attention．By contrast，a son doesn't bring more mouths into the group—he mates with females in passing pods who then go on to raise children in their own social units．
His kids are thus “someone else's problem”，Weiss explains．So，it makes sense for his mom to give more energy to him than to his sisters if she wants as many grandchildren as possible with the least competition．The team didn't find out exactly how sons prevented their mothers from having more babies．Weiss says he hopes to do more research in different species of whales．But now，killer whales remain an extreme example of parental care across the animal kingdom．“In other animals，” he says，“at some point，you just stop depending on your mom as much．”

Ⅱ．阅读七选五(共5小题；每小题2．5分，满分12．5分)
All living things need energy to move and grow．Energy can come in many different forms． 1 While energy cannot be created nor destroyed，it can be converted(转换) between different forms．
Where do plants get their energy They get their energy from the sun．Plants absorb sunlight with their leaves． 2 This chemical process is called photosynthesis．Photosynthesis means“making out of light”． The energy from the sun，light energy，is converted into chemical energy through photosynthesis．
Plants are called producers because they produce their own food．Producers form the base of every food chain in an ecosystem．Plants are eaten by animals，which are eaten by larger animals．For example，a plant takes in energy from the sun and turns it into plant food． 3 Then，a human eats the rabbit．The energy the human gets from the food is originally from the sun!
The food humans eat provides us with energy．When we chew and digest food，a chemical reaction takes place． 4 We require energy from food for basic functions，like moving and breathing．Energy from food also helps our body repair itself and stay warm．
5 Wholefoods(全天然食品)，like kale，contain lots of important nutrients，such as calcium(钙) and potassium(钾)．Sugary foods，like candy，do not contain as many nutrients．Wholefoods can provide us with enough energy over long periods of time．So are you more energized throughout the day
A．The energy produced from this reaction fuels our bodies．
B．That plant might be eaten by a rabbit，giving the rabbit energy．
C．Notice how you feel when you eat wholefoods like vegetables and fruit．
D．Through this process，energy from the sun is moved from one living thing to another．
E．They use the sun's energy to change water and carbon dioxide into plant food and oxygen．
F．The amount of energy we get from food depends on which nutrients are in the food we eat．
G．For example，light energy，heat energy，and chemical energy are all different forms of energy．
Ⅲ．完形填空(共15小题；每小题1分，满分15分)
