1.It's very cold there in winter
句意：冬天那里很冷。
根據(jù)所給詞it's可知，it指代天氣，位于句首作主語，首字母需大寫。
表語：very cold，是第二個(gè)和第三個(gè)詞
地點(diǎn)狀語：there，是第四個(gè)詞
時(shí)間狀語in winter，是第五個(gè)和第六個(gè)詞
故答案為It's very cold there in winter
2.It's said that the lowest temperature can be -40 ℃
句意：據(jù)說最低氣溫可達(dá)零下40度。
根據(jù)所給詞it's said that 可知此句是it作形式主語，that后面是賓語從句。賓語從句的主語是the lowest temperature，謂語是can be，賓語是-40 ℃ 。故答案為It's said that the lowest temperature can be -40 ℃。
3.It's comfortable to stay inside
句意：呆在里面很舒服。
根據(jù)所給詞it's和to stay inside可知，it應(yīng)該在句中作形式主語，to stay inside是真正的主語。所以it's位于句首，首字母需大寫，comfortable作表語，跟在it's后面，不定式是真正的主語位于句末。故答案為It's comfortable to stay inside。
4.It was fun to see so many beautiful things made of ice
句意：看到這么多由冰制成的美麗的東西真有趣。
根據(jù)所給詞可知it was和to see可知，it應(yīng)該在句中作形式主語，to see...是真正的主語。所以it's位于句首，首字母需大寫，fun作表語，跟在it's后面，不定式to see...是真正的主語位于句末，so many“如此多的”后面需要接名詞復(fù)數(shù)，所以是so many beautiful things made of ice，跟在to see后面，故答案為It was fun to see so many beautiful things made of ice。
5.How long does it take to fly from Beijjing to Harbin
句意：從北京飛哈爾濱需要多長時(shí)間？
根據(jù)所給詞how long可知，此句是由疑問詞how long引導(dǎo)的特殊疑問問句，位于句首首字母需大寫。特殊疑問句的結(jié)構(gòu)是：疑問句+一般疑問句+其他。
所以does it take跟在疑問句后面，這里it作形式主語，真正的主語應(yīng)該是to fly from Beijing to Harbin，故答案為How long does it take to fly from Beijjing to Harbin。
6.My parents and I all think it comfortable to travel by plane
句意：我和我父母都認(rèn)為乘飛機(jī)旅行很舒服。
根據(jù)所給詞it和to可知，此句需要用it作形式主語或形式賓語。結(jié)合所給詞my parents and I和all think可知，主語應(yīng)該是my parents and I，位于句首，謂語是all think，所以it應(yīng)該是形式賓語，comfortable跟在it后面作賓補(bǔ)，不定式to后面接動(dòng)詞原形即to travel by plane作真正的賓語。故答案為My parents and I all think it comfortable to travel by plane。
7.It's much faster to go by plane
句意：乘飛機(jī)去要快得多。
根據(jù)所給詞it's和to go可知，it應(yīng)該在句中作形式主語，to go是真正的主語。所以it's位于句首，首字母需大寫，much faster作表語，跟在it's后面，不定式to go...是真正的主語位于句末，by plane表示去的交通方式，跟在to go后面。故答案為It's much faster to go by plane。
