答案

答:A:由于藏羚羊的羊绒价格昂贵,偷猎者躲避管理保护人员,钻管理的空子进行非法偷猎藏羚羊,严重威胁藏羚羊的生存,这属于偷猎者的滥捕乱杀威胁了生物的多样性.偷猎者的枪声仍不时响起表明动物多样性丧失的主要原因是人为的偷猎与破坏.

It’s school time again! You’re probably feeling excited and maybe a little sad that summer is over. Some kids feel nervous or a little scared on the first day of school because of all the new things: new teachers, new friends, and even a new school. Luckily, these “new” worries only stick around (停留)for a little while. Let’s find out more about going to a new school.

Most teachers kick off the new school year by introducing themselves and talking about all the stuff you’ll be doing that year. Some teachers give students a chance to tell something about themselves to the rest of the class, too. When teachers do the talking on the first day, they often go over classroom rules and school rules so you’ll know what’s allowed and what’s not. Please pay close attention.

You might already know a lot of people in your classes on the first day, but it’s a great day to make a new friend, so try to say hello to kids you know and new ones that you don’t. Make the first move and you’ll be glad you did, and so will your new friend!

Seeing friends you haven’t seen in a while can make the first day a good one. You can make the day feel special by wearing clothes that you really like. Maybe you got a great T-shirt on one of your vacations, or a pair of sneakers(运动鞋). It also can make you feel good to be prepared and have all the things you need, such as pencils, folders, and whatever else you’ll be needing. But make sure that you pack them the night before in case (以防万一)you don’t have time in the morning.
