1．The pills might cure him，_____ he's taken them regularly．（　�。�
A．thanks toB．in caseC．so thatD．if only

分析 只要他按時服用，這藥或許能治好他（的病）．

解答 答案：D
句意表達的是條件；thanks to幸虧，介詞短語，后面不能接句子；in case以防萬一；so that為了；if only只要，引導(dǎo)條件狀語從句．故選D．

點評 從屬連詞是連詞的一種，用來引導(dǎo)名詞性從句和狀語從句．大致可分為三大類：that（無詞義，不做成分）if，whether （表達是否的意義，但不做句子成分）； 連接代詞：who，whom，whose，what，which，whatever，whoever，whichever（有詞義，在句子中可作主語、表語、賓語）；連接副詞：when，where，why，how，how many，how long，how far，however，whenever，wherever （有詞義，作從句的狀語）．學(xué)習(xí)時，要注意區(qū)分和掌握．

13．Beijing is hardly alone in its air pollution problems．The world Health Organization has said that roughly half of the world's urban population is exposed to pollution at least 2.5 times higher than it recommends．
While it may take years to fix this global problem，innovative minds in the Asia region have come up with creative solutions for living with air pollution．
DIY Purifier
Thomas Talhelm started worrying about the air inside his Beijing home during"airpocalypse"（空氣末日） in 2013 when Beijing's air quality index skyrocketed to a terrifying 755．
The scholar couldn't afford the luxury of an expensive air purifier．"Filters （過濾器） are actually very simple-a high efficient filter is all you need to get over 96% of the PM2.5，"he said．
With three of his friends，Talhelm created Smart Air，an air purifier consisting of a basic household fan with a high efficient filter attached to it．
It works as efficiently as the big brands selling for thousands of dollars，removing more than 90 percent of PM2.5 in your room，according to Talhelm's research．
Invisible Mask
Infipure's"nose mask"claims to cut 99% of PM2.5 without the trouble of a surgical face mask．
The filters，made from special materials，are inserted into your nose and aim to be undetectable．
"People care about their health，but don't want all the downsides that come with a traditional face mask，"Infipure co-founder Francis Law explained．
Plant Backpack
Taiwanese artist Chui Chih has designed a survival device for an apocalyptic world．
Named Voyage on the Planet，a potted plant is housed inside a clear backpack hooked up to two tubes to bring fresh air to a face mask．It's a bold，abstract idea from an oxygen tank．
Smog Vacuum
Daan Roosegaarde has been working on a smog vacuum that will suck pollutants from the sky to the ground like a vacuum，making way for clean air．
A byproduct of this smog vacuum，namely The Smog Free Tower，is the"smog ring"-a piece of jewelry made from smog particulates（微粒）．
"The pollution we suck up，the small particulates，we don't throw them away．We put them under pressure for a couple of weeks and they crystallize，creating something like a diamond，"Roosegaarde explains．
 
70．Thomas Talhelm invented Smart Air for all the following reasons exceptD．
A．the high price of the big brands
B．the help from three of his friends
C．the poor quality of the indoor air
D．the simple principle behind the device
71．If someone wants to travel around in those polluted days，which product will he most probably choose for the sake of convenience？B
A．Smart Air．
B．Infipure's nose mask．
C．Voyage on the Planet．
D．The Smog Free Tower．
72．In which solution the inventor also makes use of the dust collected from the polluted air？D
A．DIY Purifier．
B．Invisible Mask．
C．Plant Backpack．
D．Smog Vacuum．

14．Raising Confident Kids
Self-esteem（自尊） is a collection of beliefs or feelings we have about ourselves．Having a healthy self-esteem can protect us through difficult times and help us remain focused on what is important to us．Research shows that children with high self-esteem grow up to be more confident adults．Self-esteem building should start from young．（36）F
Praise actions
Young children need feedback．It's how they measure their actions and it plays a role in learning from experience．Provide specific praise about actual actions performed and efforts made in the process．（37）D．
Identify strengths
Preschoolers are always watching each other．On the bright side，they learn new things from each other．On the other side，they can become self-critical when they see a peer accomplishing something they still struggle to do．（38）ETell your children to focus on their strengths when they start to draw comparisons．
Foster（培養(yǎng)） a sense of belonging
Young children may not understand how peer pressure （同齡人的壓力） works，but they feel it when they're being excluded（排除）．Show your children that they are important by listening to and responding to their needs and ideas．As much as possible，save grown-up conversations for later so that you can have family conversations． （39）C
（40）AAs much as they need us，they also need to work on taking small steps towards independence．When they know they can do things，they feel more confident．Teach problem-solving skills．Step aside and let them work on challenges before jumping in to help．Help by asking，"How can we do this in a different way？Let's come up with some ideas together．"Getting kids involved in problem-solving teaches them how to deal with challenges in the future．
Building and maintaining healthy self-esteem can be a lifelong process，but the sooner you start，the more confident your children will become．

A．Encourage Independence
B．Spend quality time with children
C．Try to address their concerns as they arise，no matter how minor．
D．If praise is only attached to success，kids will focus on"winning"．
E．Be sure to point out your children's strengths regularly and be specific．
F．Below are some tips to help you promote your children's self-esteem．
G．Each parent has the responsibility to help children to become confident．
