(2018·济南模拟)As her son Cameron sits at his laptop completing a task for his math degree course, Alison Thompson, a full-time mum, is busy helping her daughter Emma (two years younger than Cameron) get dressed.While help has always been available for Emma, Alison and her husband also have to fight to get Cameron the support he needs.“People could see that Emma has special needs but because Cameron was doing so well at school, his teachers never thought there was a problem with him，”says Alison.

It took Alison and her husband a while to realize their son was different.Cameron's ability didn't become clear until he began primary school.Once he even corrected the teacher when she told the class that zero was the lowest number.Cameron told her she was wrong because there were negative numbers (负数)．He was four at the time.Now 14-year-old Cameron is at secondary school, studying for a distance learning math degree with the Open University, having_sailed_through_his_GCSE at 11 and his A-level at 12, achieving top grades.

Bethany, another daughter of Alison, is bright too but not gifted.She is the one who will remind absent-minded Cameron to put on his coat.She also helps him out in social situations.

Emma attends a specialist school and the family is quick to celebrate her successes too.“The other day she did up the buttons on her coat, which was real progress，”Alison says.

Late last year the Thompsons took part in a television documentary (纪录片) to prove that not all gifted children are the result of extremely ambitious parents.Gifted children need support too but their lives don't have to be that different.Cameron is an example.

Driving on up to Yosemite with my family was exciting but nerve-racking (神经紧张的). I had never been to such an amazing national park before, yet I wasn't the most athletic person, so I knew that I couldn't stick through all the hiking up and down. It actually ended up being a fun and adventurous experience.

The ride there was definitely long but worth it. As I woke up from my nap, I saw the beautiful scenery of the tall mountains and beautiful streams. The trails were made nicely for visitors. The waterfalls were breathtaking. Climbing up rocks was one of my favorite parts. Even though I fell a couple of times, I still had a lot of fun. The fact that my family and I spent so much time together trying to find out which route to take and what views to watch really brought us closer together.

The great thing about nature is that, it's just you, the views, and the people around you. There's nothing there to bother you and it's the best way to relax and enjoy yourself. Yosemite has 5 of the world's highest waterfalls, and about 300 lakes. The structure of each mountain is incredible; it's formed in ways that almost take your breath away. Some of them are of a deep dark color with waterfalls forming; some are formed with spots of green peeking (窥探) out. It's definitely something you wouldn't want to miss.

Yosemite isn't the only great National Park but based on my experience I highly recommend going out and enjoying nature with family and friends. It's a great time to bond, laugh, and take in what Mother Nature offers.

语篇解读：文章记叙了作者一家去约塞米蒂国家公园游览的所见所闻，与家人一起出游其乐无穷。作者建议读者多外出走走，享受大自然之美。 5．The author writes the first paragraph mainly to ________. A．introduce the topic of this passage B．offer an example to us C．tell us his future plan for hiking D．describe a national park

解析：选A 推理判断题。文章第一段第一句首先提到Yosemite，该段最后一句“It actually ended up being a fun and adventurous experience.”起到承上启下的作用，下文展开介绍作者此次去约塞米蒂国家公园游览的所见所闻。由此可推测，作者写第一段是为了引出文章话题。故选A项。

6．While climbing up rocks, the author was ________. A．nerve-racking C．pleased

B．injured D．worried

解析：选C 细节理解题。根据文章第二段第五、六句“Climbing up rocks was one of my favorite parts. Even though I fell a couple of times, I still had a lot of fun.”可知，攀岩是作者的最爱之一，尽管摔倒了好几次，但仍然很开心。故选C项。

7．According to the passage, Yosemite ________. A．is crowded with visitors every day B．is the only great National Park C．is worth traveling to

D．is nothing but a common destination

解析：选C 推理判断题。根据文章第二段第一句“The ride there was definitely long but worth it.”及全文对约塞米蒂国家公园的美景描述和作者一家人从中得到的乐趣可知，该公园值得游览。故选C项。

8．The author advises us to________. A．keep a good bond with other people B．visit Yosemite now and then C．try to protect the environment D．go out to enjoy the beauty of nature

解析：选D 细节理解题。根据文章最后一段第一句“...based on my experience I highly
