Answer 1

【答案】

【1】Eric goes swimming. James goes cycling. Sue goes swimming. Kim goes shopping

【2】4 days.

【3】24

【4】19

【5】12 years old.

【解析】

【1】根據(jù)文意可知，四個(gè)朋友去游泳、購物和騎自行車，他們每個(gè)人都做了一件事。Eric說我沒有騎自行車；James說他沒有去游泳；Sue說男孩們都沒有去購物；Kim說Sue去游泳了。根據(jù)他們四個(gè)說的話，我們先可以確定Sue去游泳了；然后根據(jù)Sue的話男孩們沒有去購物，以及Eric說他沒去騎自行車可知Eric去游泳了，以及James的話可知James去騎自行車了，又因?yàn)槊總�(gè)人都做了一件事，所以Kim只能是去購物了。

【2】根據(jù)題意可知，一個(gè)工人6天能完成一份工作，另一個(gè)工人12天完成一個(gè)工作，他們共同合作的話，幾天完成。設(shè)整個(gè)工作量為1，那么第一個(gè)工人每天完成整個(gè)工作量的1/6,第二個(gè)工人每天完成工作量的1/12，設(shè)兩個(gè)工人合作x天完成，根據(jù)題意得x/6+x/12=1，解得x等于4.故答案是4 days。

【3】根據(jù)題意可知，Sally最后剩下了六顆糖，那么她第二次給別人的糖也是六顆，所以第一次給別人糖之后，包里剩下12顆糖，所以Sally第一次給了別人12顆糖，那么她一共有24顆糖。

【4】題干告訴我們房間的號(hào)碼和這個(gè)人的名字是有聯(lián)系的，因此我們要找到房間號(hào)和這個(gè)人名字的聯(lián)系，就能知道答案。通過前三個(gè)人的房間號(hào)和名字我們可以發(fā)現(xiàn)，房間號(hào)就是名字首字母在字母表中的順序，如T是第20個(gè)字母；L是第12個(gè)字母；P是第16個(gè)字母。由此可知，Sophia第一個(gè)字母S是第19個(gè)字母，所以房間號(hào)是19.

【5】根據(jù)題意Alan is half of Sean’s age and is three years younger than Sam可知，Alan比Sam小三歲，所以當(dāng)Sam15歲的時(shí)候，Alan應(yīng)該是12歲了。
