Part 5: Sentence structure

(1) At Los Alamos, Slotin, then aged thirty-five, was concerned with the

assembly of pieces of plutonium, each of which alone is too small to be

dangerous, and which will only sustain a chain reaction when they are put

together. (Para. 1)

斯洛廷当时 35 岁，在洛斯阿拉莫斯研究钚块的反应堆。每一块单独的钚块非常小， 并不足以产生危险，只有放在一起才能产生链式反应。

本句中需要注意的是“ to”结构。“ to”结构一般表示否定含义，意为 “太......以致于不能”。

e.g. He is too old to work. 他年纪太大了已经不能工作了。

但是如果“ to”结构前面有only，all，not，but，never，simply，just，only 等 词 时，too 后 面 是 eager，anxious，pleased，kind，willing，apt，ready，inclined， glad，quick 等词，这时的“ to”结构表示肯定含义。

e.g. He is too ready to promise. 他总是轻易承诺。

I am only too glad to help you. 我非常乐意帮助你。

I know but too well to hold my tongue. 我深知少说为妙。

Slotin moved at once; he pulled the pieces of plutonium apart with his bare

hands. (Para. 3)

斯洛廷立即采取行动，徒手将钚块拆开。 本句中需要注意动词 move

的用法，意思是“采取行动”。

e.g. Unless the employers move quickly, there will be a strike. 雇主若不尽快采取措施，就要引起一场罢工。

本句中还需要注意词组 bare hands 的用法，意思是“徒手”。

e.g. Rescuers were using their bare hands to reach the trapped miners.

救援人员正徒手营救被困矿工。

(2) This was virtually an act of suicide, for it exposed him to the largest

dose of radioactivity. (Para. 3)

这个举动无异于自杀，因为这会让他暴露在大量的辐射下。

本句中需要注意动词 expose 的用法。

(1)动词 expose 的基本含义是“有意或无意地使某人 / 物从隐藏之处或掩盖之中暴

露出来展示在他人面前”，也可表示“把某些丑恶的，见不得人的东西揭露出来”，还可 以表示“撕下面具”，即“揭穿”。

e.g. He lifted his T-shirt to expose a jagged scar across his chest. 他撩起

T 恤衫露出胸口上的锯齿状伤疤。

The report exposes the weaknesses of modern medical practice. 报道揭露了现代医务工作的不足之处。

(2)expose 是及物动词，接名词或代词作宾语，可用于被动结构中。

e.g. The report revealed that workers had been exposed to high levels of

radiation.

(3)expose的宾语后面通常可接介词to构成“expose sb./sth. to sth”的结构，表示 “将......暴露于...... ;接触;体验”。

e.g. Potatoes turn green when exposed to light. 马铃薯在光的照射下会变绿。

Some children are never exposed to classical music. 有些孩子从来没有接触过古典音乐。

Part 6: Exercise

Part 2: Vocabulary Building

学生到课情况 应到： 实到： 其他情况：

1. 本篇课文为夹叙夹议文，其中既有叙事，又有作者对叙事的评价。通过学习该文章，可以增强学生们阅读和书写夹叙夹议文的能力。另外，本篇文章中动词的时态变化非常值得学习。在英语语法中，动词的时态变化是极为重要的一环。通过这篇文章，同学们对动词时态，尤其是被动时态的使用有了更深刻的理解。第三，本篇文章后两段的理解较为有难度，存在很多隐藏信息需要读者推敲，经过学习，同学们理解了文意课后小结

中所蕴含的隐藏信息。

2. 本课的语法是动词的过去时态。动词的时态对于同学们来说并不陌生，但大多数同学掌握并不扎实，同时也不系统，老师先通过让同学们观看英语母语者的教学视频，深刻理解叙述时态，然后通过画表格的方式，帮同学们梳理了动词的时态。

3. 本课的词汇学内容具有一定的难度，但有章可循，老师对规律进行了总结，便于同学们同学学习。

4. 本课的culture tip可拓展性较弱，且同学们对此较为不熟悉，难以进行材料的搜集，因此同学们presentation的内容普遍扩展不足。
