【解析】文章描述作者其西藏旅行的一次经历。

【1】考查现在完成时。句意：自从上大学，我去过很多地方旅行。since表示自从…到现在。故主句用现在完成式。故用have traveled。

【2】考查代词。句意：让我印象深刻的是我去年去西藏的一次旅行。这里用形容词性物主代词修饰名词travel，故用my。

【3】考查冠词。句意：当火车接近西藏的时候，我感到头疼。have a headache头疼，头痛。故用a。

【4】考查动词时态。句意：然后我就觉得呼吸困难，感到疲惫。联系上文可知这里是在描述去年的旅行经历，用过去式。故用found。

【5】考查形容词。feel tired感到疲惫的。故用形容词形式的tired。

【6】考查连词。句意：西藏被成为“世界屋脊”，有很多著名的名胜古迹。根据句意可知前后句时并列关系，故用and。

【7】考查名词。places of interest名胜古迹。故这里用places。

【8】考查比较级。句意：因此当我感觉好点之后，我迫不及待地向这些名胜古迹出发了。根据句意可知这里用比较级，故用better。

【9】考查非谓语动词。句意：看到珠穆朗玛峰顶在七月也被白雪覆盖，我非常高兴。be happy to do很高兴做某事。故这里用to see。

【10】考查介词。in July在七月，月份前面加介词in，故这里用in。

since作连词引导时间状语从句的用法：

一、若since引导的状语从句的谓语动词是终止性的过去时，则从句表示的时间是“从动作开始的那一时刻起”。如：

He has studied very hard since he came to our school.

自从他来到我们学校，他学习就非常努力。

We have been missing them since they left here

自从他们离开这里，我们就一直很想念他们。

这是最常见的一种用法，此处不再多述。

二、若since引导的状语从句的谓语动词是持续性动词或表示状态的动词的过去时时，则从句表示的时间是“从那持续动作或状态结束时算起”。如：

I haven’t heard any noise since I slept. sleep 为持续性动词，sleep的动作结束时，即“醒来”时，这句应译为“我醒后还未听到任何声音”。

John is now with his parents in New York, it is already three years since he was a teacher约翰现在和父母一起住在纽约，他不当教师已经三年了。

三、若since引导的状语从句的谓语为持续性动词的现在完成时，则表示动作和状态延续到现在（说话时刻），其表示的时间的起点应从动作发生之时算起。如：

I haven’t heard from him since he has lived there。

这里has lived表示动作的持续性，时间的起点应从：“开始居住”时算起。因此此句可理解为“自从他（开始）住在那儿起，我就一直没收到他的来信”。

Since we have owned a car, we have gone camping every year。自从我们自己有了汽车，我们每年都去野营。

试比较：

Since I’ve been at this school, we have had three headmasters.

自从我到这所学校，我们已换了三个校长了。

Since I was at this school, they have had three headmasters.

自从我离开这所学校，他们已换了三个校长了。

2. He has never been to see me since I have been ill. 自从我生病以来，他从未来看过我。

He has never been to see me since I was ill. 自从我病愈以来，他从未来看过我。

由此可见，since引导的从句持续动词的一般过去时和现在完成时所表示的意思恰好相反。换言之，前者以肯定的语法形式反映着否定的逻辑内容，而后者的形式与内容是一致的。

至于It is +一段时间+since…的句型与It has been +一段时间+since…意思相同。前者是规范说法，后者是口语说法。应注意的是，在这种结构中，since引导的从句绝对不能用否定式的谓语动词来表示否定意义，下面两句都错了：

It is a long time since he didn’t study English.

It’s two months since you didn’t come to see me.

正确的说法为：

It’s a long time since he studied English 他好久没学英语了。

You haven’t come to see me for two months. 你有两个月没来看我了。
