right，even squirrels are endangered，specifically the san joaquing round squirrel. native to california，usa，these guys have been disappearing since 1979 on account of the construction and human development going through their habitat. their total population is unknown，but it could be anywhere between 124,000 and 413,000.giraffesthe international union for the conservation of nature recently put giraffes at a vulnerable(脆弱的) status，the level just before endangered. the giraffe population has declined 40 percent in the last 30 years，primarily due to loss of habitat and illegal hunting. some giraffes are killed just for their tails，which are considered status symbols in africa.asian elephantsthe main threat to asian elephants，one of the most intelligent animals，is their shrinking habitat. as the human population grows，people invade their land to build roads and railway tracks. elephants in myanmar are at an especially high risk for being captured and traded or used illegally in the tourist industry. fewer than 50,000 are left on the entire continent.1whatisthetotalpopulationoftigerslivinginthewild?aaround3,890.b50,000.c124,000.d413,000.答案a解析细节理解题。根据tigers中最后一句“only about

marathon this year，one of the top class marathon races in china. i enjoyed it in my own way，but it may be a little different compared with my fellow chinese runners.this race was my 87th marathon，if i take into account some ultra marathon events. i have been to a few places to experience other marathons besides my home country，malaysia，like chicago，tokyo，gold coast，bali，hong kong，singapore，bangkok，borneo，kuching，songkhla，phuket，etc. so，i can compare beijing marathon with my various experiences.since this years beijing marathon was the starting station for china major marathon league and also asia major marathon league，the organizer invested a lot of effort，which i recorded with my own eyes and my camera，so that i could share the nice experience with the runners in my home country and to show how maximum effort should be made to make the races successful.from my view，the wonderful experience starts from the marathon expo. the expo not only manages the crowd，but also limits the entry tickets to only runners with valid passes. whats more，there are many services inside expo，like free photo taking and printing with makeup，and free race tshirts printed with different motivational words. the organizer was so nice to put out all the previous beijing marathon souvenirs and magazines on display so that we could read the history and background of beijing marathon.on the race day，though the event started at 7：30 am.，the chilly weather was still acceptable as i was wearing a longsleeved tshirt with the race tshirt outside，which was good as it blocked the cold wind in the early morning and the sun in the afternoon.when i returned to malaysia and shared about 1,200 of beijing marathon pictures and the experience，many of malaysian runners showed their interest，but i told them，they needed to pray for luck during ballotselection.still，thanks to the organizer and all volunteers who made their effort for runners to enjoy the 42.195 km marathon race，i would rate this year the best compared to previous beijing marathons.4from the passage，we know the author.ahas been to many foreign cities besides beijingbhas little experience of running a marathon beforechas never come to china before this race in beijingdhas the same opinion on this race with chinese runners答案a解析细节理解题。从第二段第二句“i have been to a few places to experience other marathons besides my home country，malaysia，like chicago，tokyo，gold coast，bali，hong kong，singapore，bangkok，borneo，kuching，songkhla，phuket，etc.”可知作者去过很多外国城市，所以a项正确。25the author would share the experience with the
