When I met Larry, my husband-to-be, he came with an eighteen-month-old daughter, Mckenna, and a four-year-old son, Lorin. I quickly {#blank#}1{#/blank#} (fall) in love with Lorin and Mckenna, {#blank#}2{#/blank#} the children's mother, Dia, was a different story.

    There was a feeling of hostility（敌意）between us. Sometimes I wished that she would simply disappear. Then the children could stay with us— {#blank#}3{#/blank#} (true) be mine—and we could be a “real” family.

    Years {#blank#}4{#/blank#} (pass) by, something changed. I began to enjoy talking to Dia about the Kids. And she realized that there were very few people in the world {#blank#}5{#/blank#} were as interested in her children {#blank#}6{#/blank#} I was. One year, Dia sent me a Mother's Day card thanking me for “co-mothering” her children.

    Thank you, Dia, for being kind enough {#blank#}7{#/blank#} (share) your children with me. Thank you for making Christmas morning {#blank#}8{#/blank#} exciting and warm time, so the children never had to feel sad on these important days. We all could sit around the tree. There {#blank#}9{#/blank#} were, you and your husband, Larry and me, the kids ... and {#blank#}10{#/blank#} (surprise), I felt at home.

    As is known to all, a positive parent-child relationship is {#blank#}1{#/blank#} (benefit) to the physical and mental{#blank#}2{#/blank#} (grow) of children, but keeping a healthy parent-child bond {#blank#}3{#/blank#} (need) the efforts of both parties.

    Parents should take the responsibility {#blank#}4{#/blank#} (improve) their relationship with the children. What matters is spending quality time with their children, {#blank#}5{#/blank#}tight their schedule is. For instance, they can eat {#blank#}6{#/blank#} (meal) together, go to sporting events together or watch their children's favorite

TV shows together, {#blank#}7{#/blank#} can contribute greatly to making their children feel safe and {#blank#}8{#/blank#}(love).

    Children, on the other hand, should let their parents know they appreciate what their parents {#blank#}9{#/blank#}(do) for them. If possible, they can give their parents a gift on a special day or help with housework {#blank#}10{#/blank#} a regular basis. The healthy parent-child relationship is without conflict. But as long as parents and children make joint effort, they can settle the conflict and enjoy their time together.

    Two new satellites of BeiDou Navigation (导航) Satellite System (BDS){#blank#}1{#/blank#}(send) into space on a Long March-3D carrier rocket from the Xichang Satellite Launch Center in Sichuan Province, China at 2:07 a.m. on November 19, 2018. The satellites entered a Medium Earth orbit (轨道) {#blank#}2{#/blank#}(safe) more than three hours later and will work with 17 other BDS-3 satellites already in space. They are also the 42^nd and 43^rd{#blank#}3{#/blank#}(member) of the BDS satellite family.

    China launched these satellites with the aim of providing navigation services{#blank#}4{#/blank#}countries and regions which participate in the Belt and Road Proposal by the end of 2018. “This is a key and{#blank#}5{#/blank#}(value) step for BDS developing from a Chinese experimental system to a regional and then a global navigation system,” said Yang Changfeng, chief expert{#blank#}6{#/blank#}contributed much to the BeiDou system. The positioning{#blank#}7{#/blank#}(accurate) of the BDS-3 system has been improved to 2.5 meters to 5 meters, said Yang.

    {#blank#}8{#/blank#}(name) after the Chinese term for the Big Dipper, the BeiDou system has been serving China for 18 years where another six BDS-3 satellites will be put into the Medium Earth orbit from 2019 to 2020. The system is expected{#blank#}9{#/blank#}(provide) first-class services around{#blank#}10{#/blank#}globe by the end of 2020.

    Happiness can {#blank#}1{#/blank#}(describe) as a positive mood and a pleasant state of mind. There are many factors contributing to happiness.

A person {#blank#}2{#/blank#} an obviously ideal situation is not necessarily happy. The ideal situation may have little to do with his actual feelings.

A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}3{#/blank#} are only chief factors if the person is {#blank#}4{#/blank#}(serious) undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly {#blank#}6{#/blank#} they have more opportunity to control their {#blank#}7{#/blank#}(life). Yet people with a high income and a college education may be {#blank#}8{#/blank#}(little) happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope) with a health problem can contribute to happiness.

    CPR is an effective form of first aid {#blank#}1{#/blank#} (give) to the victim whose heart stops. Doing it can increase the chance of the victim's {#blank#}2{#/blank#} (survive). So knowing CPR can be a real lifesaver.

    How to give CPR? There are {#blank#}3{#/blank#} (simple) three steps. Firstly, roll the victim onto his back and do chest compression (按压). {#blank#}4{#/blank#} this way, it keeps blood flowing to the brain, heart and other organs. To perform the compression, place one hand over {#blank#}5{#/blank#} other and press firmly on the victim's chest many times in a row, {#blank#}6{#/blank#} (push)at least 2 inches deep on every compression. Then after compressions {#blank#}7{#/blank#}(complete), check the air way {#blank#}8{#/blank#} (see)whether the person is breathing. If not, perform mouth-to-mouth rescue breathing, {#blank#}9{#/blank#}helps to move the oxygen down into the victim's lung. And chest compression should start again right after the two breaths are given.

    Learn CPR, for you never know when you might need {#blank#}10{#/blank#}. And it feels good to know that you could help in case of emergency.

Yoho National Park is a Canadian national park. {#blank#}1{#/blank#} (cover) an area of about 507 square miles, it was established in 1886.
