I remember the day when I first learned to ride a bike.It was a frightening，yet fun experience.My grandfather was the one who taught me and he helped me when I got hurt.The first time I got on a bike，I had no idea what I was doing，and just about everything went wrong.My grandfather told me to just put my feet on the pedals(脚蹬子)and start cycling.He also told me he would hold onto the back of the bike the whole time，yet he didn't.
As soon as I started trying to balance myself，he let go.I happened to look back just then.I was scared to death that I was going to fall and hurt myself.When I was scared，my mind went blank from cycling，and I just wanted off.I forgot how to use the brakes(车闸)and fell right off the bike.My grandfather kept encouraging me to get up and try again，and after about 15 minutes，I finally stopped crying，got up and tried again.
As soon as I started riding again，my pants got caught in the chain，and I fell flat on my face and hit my nose.My grandfather decided to call it a day and try again the next morning.The next morning I woke up bright and early，and was very eager to try to ride my bike.My nose felt better，so I wasn't that afraid of falling anymore.
Though I knew there were a lot of difficulties on the way to mastering the skills in riding a bike，I believed I could do well with my grandfather's help.After all，riding a bike was what I wanted to do eagerly.

Many kids help out around the house with chores(家务活)such as emptying the dishwasher，putting laundry away，and taking out the trash.In exchange，some kids get some rewards such as extra computer time.
But some people do not think that kids should get rewards for doing chores.Susie Walton，a parenting educator and family coach，believes that by rewarding kids，parents are sending a message that work isn't worth doing unless you get something in return.“Running any kind of household is a team effort，” Susie said.“A home is a living space for everyone in the family.It's important for kids to see that we all have responsibilities in the house，and that families decide together how they want their home to look，and how they are going to keep it looking like everyone wants it to look.”
Other people believe that getting a allowance or other rewards motivates(激励)kids to do chores，and it also teaches them real world lessons about how we need to work to earn money.There are also new applications that give kids points and digital gifts that can be redeemed(兑换)either online or in the real world.With the ChoreMonster app，kids earn digital(数字的)points by completing chores that they can turn in for real life rewards such as extra Xbox time or a trip to the mall.“Our goal is to encourage kids to earn rewards，” says Chris Bergman，founder of ChoreMonster.“Kids need positive reinforcement to help motivate them.”
What do you think Should kids be rewarded for doing chores Or should kids help out around their homes without getting anything in return
Write a 200 word response.Send it to advicetoyou@.Your response may be published in a future issue of Time For Kids.Please include your grade and contact information of your parent or teacher if you want your response to be published.The deadline for responding is February 18.

Have you ever imagined that your T shirt can cool you down by up to 5 ℃ on these hot summer days Thanks to a recent discovery，the possibility is getting closer.While there are many technologies that manage to keep the body warm，this amazing invention aims to offer real comfort for those who want to feel cool and fresh on extremely hot days.
Its inventors，engineers Ma Yaoguang of Zhejiang University and Tao Guangming of Huazhong University of Science and Technology in China，took a completely new technique.They designed a special textile(纺织品)that can take in body heat and give off its energy into space.This means that，even when it looks like you are wearing a regular shirt，you are actually wearing something that works like a mirror.
Research at Stanford University in 2017 had already managed to cool the wearers by 3 ℃，but this experiment was limited.So researchers still need to do more experiments to see the new technique to decide how effectively the new material cools while the wearers are standing or walking，and not directly facing the sky，like in their experiments.They also need to examine how well it works when T shirts are not in close touch with the skin.
Inventors Yaoguang and Guangming note that the new material will increase the costs by just 10 percent.“It means everybody can get a T shirt and the cost is basically the same as their old one，” Yaoguang said.
So if you are an athlete or simply someone that has to deal with the extremely high temperatures，be patient because your days of feeling hot and bothered may be coming to an end!

Do not force your family to spend time together. 37 Find things they enjoy and work around it to draw everyone near.If your child likes games，you could try one of the new interactive(相互作用的)games.
Spend time in the kitchen together.If you have young kids，they love to make a mess and that is why I suggest the kitchen.Bake some cupcakes or cookies with them，but let them get involved by stirring(搅拌)or adding the ingredients(原料). 38 When these are done，you can sit down and have an awarding treat with your child.
Always remember that one child is not the same as another.I have two children.My older son is a perfect little angel，while my little son is constantly trying to get into trouble. 39 For example，I can go to movies with my older son but my little son has to stay at home.
40 No matter how old they are，they want their parents to notice them and to take a part of their lives.Remember，do not push them but find a common ground.If your kids like sports，you can play a game of basketball or go to a game with them.If your kids will not come to you，then you have to go to them.
A．They will love this.
B．Want parents' attention.

语篇解读　本文主要介绍了关于巧克力的几项研究，但是这些研究都不是结论性的。
56．解析：　on/upon　考查介词。effect on/upon为固定搭配，意为“对……的影响”，故填on/upon。
57．解析：　analyzed　考查动词的时态。分析句子结构可知，空处所填是从句的谓语动词，且主句使用了一般过去时，从句的主语和谓语是主谓关系，故填analyzed。
58．解析：　is processed　考查动词的时态和语态。分析句子成分可知，it和process是动宾关系，故应用被动语态，且由从句中的vary可知，此处也应用一般现在时，故填is processed。
59．解析：　entirely　考查词性转换。空处修饰动词affect，所以应用所给词的副词形式，故填entirely。
60．解析：　which　考查定语从句。分析句子成分可知，空处引导非限制性定语从句，空处在从句中作主语，且先行词为物，故填which。
61．解析：　amounts　考查名词的单复数。amount是一个可数名词，其前没有冠词修饰限定，应用名词的复数形式，故填amounts。
62．解析：　higher　考查形容词的比较级。分析句子结构并结合后面出现的lower可知，空处也应用所给词的比较级形式，故填higher。
63．解析：　addiction　考查词性转换。分析句子成分可知，空处应用所给词的名词形式，且此处表示“食物成瘾”，应用名词的单数形式，故填addiction。
64．解析：　seen　考查非谓语动词。分析句子结构可知，空处应填非谓语动词形式，且逻辑主语与see是动宾关系，故填seen。
65．解析：　though/however　考查副词。分析句子成分可知，空处应为副词。结合句意可知，应填though/however。

Dear Tom，
I am sorry to hear your tense parent child relationship.The truth is that everyone will have one of those periods when things seem to be going wrong.As for the problem，I'd like to share my opinions with you.
To begin with，you'd better have honest communication with your parents，which will allow both parties to stand in the others shoes.What's more，it would be a good idea if you take part in family activities regularly.Last but not least，you should not quarrel with them whenever you disagree with them，for that only makes matters worse.
I believe if you follow my advice，you will get along well with your parents.
Yours，
Li Hua
