1. We’re trying to save the manatees!我们正在设法拯救海牛！ [分析try的相关用法：

(1)Try 在本句中是动词，表示“试图；设法”。

例：I’m trying to work out the math problem． 我正设法算出这道数学题。 (2)动词try还表示“试”“尝试”“试用”。

例：—Have you tried this medicine? 你试过这种药了吗?

——I’ve tried，but it doesn’t work． 我已试过了，但不起作用。 (3)和 try搭配的词组：

try to do sth. 设法做某事；try on试穿；try out 尝试，试验 ；

try one’s best 竭尽全力；have a try 试一下； try doing sth． 试着干某事 ① I’ve bought a dress．But I haven’t tried it on yet． 我买了件衣服，但还没有试穿过。

② I’ll try my best to catch up with others. 我将竭尽全力赶上别人。 ③Let me have a try. 让我试一下。

2．I am writing to say that I am against building a new zoo in our town . 我写这封信是要反对在我们镇上建一个新的动物园。

[注意]be against意为“反对……，不同意”，反义词组为be for“赞成”。 例：①No one is against this proposal． 没有人反对这项建议。

④Are you for or against this plan? 你是赞成还是反对这项计划?

3. The animals are kept in tiny cages and can hardly move at all .动物被关在很小的笼子中而且几乎不能动。

[分析](1)此句用了一般现在时的被动语态，其结构为：is / are+过去分词。 例：Chinese is spoken in our country．在我们国家人们说汉语。 (2)hardly是否定副词，意为“几乎不，几乎没有”。

例：There is hardly any water in the bottle，is there?

瓶子里几乎没有水，是吗?

6．真抱歉让你等这么久。 I’m sorry to you so long． 四、疑难句子

1．I’ve visited a lot of zoos in my life，and I have never seen one I like or one that was suitable for animals to live in.在我一生中，我已经参观了很多动物，而从未见过一所我喜欢或是适合动物生活的动物园。 [分析]该句中含有两个定语从句。第一个定语从句I like 修饰前面的代词（先行词）one ，省略了关联词that ，第二个定语从句that was suitable for animals to live in 修饰前面的代词（先行词）one 其中that 既是关联词，同时又充当从句的主语。此处to live in 与前面的代词one 构成逻辑上的运宾关系，因此这里的介词in 不能省略。

[归纳]visit 的用法 （1）visit作及物动词，意为“参观，访问”“拜访，探望”。“来访者，参观者”是visitor。

例：①The president visited five countries in Europe. 总统在欧洲访问了5个国家。 （2）visit 也可用作名词，表示“参观，访问”的意思，常构成词组make a visit to …… （参观或访问……）；be on a visit to ……（正在参观/访问……之中）；go on a visit（去访问，去参观）。

例：This is my first visit to Beijing. 这是我第一次来北京游览。 2．I visited our zoo yesterday and I was very surprised to find hardly anyone there . 昨天我参观我们动物园时，惊奇地发现那几乎没有人。

[分析]surprise在这里是动词“使惊奇”，这句话既可以理解成被动语态，也可以理解为把surprise变成了形容词surprised，be surprised to do sth. 表示“对做某事感到惊奇”。surprise类似的用法还有be surprised at sth，意为“对某事感到惊奇”，后面还可以接从句。同时surprise后可以直接加人，表示“使某人惊奇”。 例：①I’m very surprised to see you here. 真没想到会在这遇见你。 ②We are all surprised at the news 我们听到这个消息都很惊讶。 ③You surprised me．你吓到我了。

[拓展]surprise还可以作名词，意为“惊奇，惊讶”。to one’s surprise意为“令某人惊奇的是”，in surprise意为“惊奇地”。

例：①To my surprise，the plan succeeded． 令我惊奇的是计划成功了。

②She looked up in surprise when I shouted． 我叫喊时她惊奇地抬起头来看。 自我测评
