请注意区别assure，ensure，insure和secure这四个动词。

assure指以十分肯定的语气向别人保证某事一定发生，多用assure sb. of / that在结构中；ensure意为确保某种行动或动因的结果一定会发生，后面可以跟sth.或that从句，但不能带双宾语；insure意思是"给…保险"；secure的意思是make safe（使安全）。

1) He assured me that Dr. Baker would come.（他向我保证贝克博士会来。）

2) To ensure the child's quick recovery, the doctor gave him three different medicines.

(为了保证孩子尽快康复，医生给了他三种不同的药物。)

3) The house is insured against fire.（这房子保了火灾险。）

4) They tried their best to secure the bridge from further attack.（他们尽力保护桥梁免受进一步的攻击。）

3. College and his preparation for a career were his only priorities.请注意区prepare 和prepare for的区别。

prepare sb. or sth. 指make them ready for an event or action that will happen in the future，如：

We have to prepare our lessons carefully.（我们得仔细备课。）

prepare for an event or action指get oneself ready for it; make plans for it so that it and prepared when it happens, 如：

The children washed out hands and prepared for the meal.（孩子们洗好手准备吃饭。）

名词preparation通常用在短语make preparations for和in preparation for当中，如：

1) They were making preparations for the old man's funeral.（他们在为老人的葬礼做准备。）

2) We will have to collect new material in preparation for the experiment.（我们得收集新资料为实验作准备。）

priority指 give priority to和 take / has priority当中。如：

1）This project has priority over all others.（这个项目比所有其他项目都更受重视。）

2）Education is given first priority in their family.（教育在他们家是予以最优先考虑的问题。）

4. This student has seen being physically fit as an end rather than the means we know it to be.

see sth. as意思是"把…看作为"，我们以前学过不少类似的短语，如：regard…as，look upon…as，think of…as，view…as等等。

being physically fit意思是"身体健康"。

an end rather than the means意思是"是一种目的而不是达到目的的方法"。 rather than意思是"而不是"。

1）He was seen as the most capable person in the company.（人们认为他是公司最能干的人。）

2）We saw her silence as consent.（我们把她的沉默看作为同意。）

3）To be physically fit is our greatest wish for grandfather.（身体健康是我们对爷爷的最大希望。）

4）You need to do more exercise if you want to be physically fit.（如果你想身体健康，就需要进行更多的锻炼。）

5）He came all the way to China for promoting friendship rather than for making money.

（他千里迢迢来到中国不是为了赚钱，而是为了增进友谊。）

5. His opinion is one of the many feelings, pro or con, that people hold about their personal involvement in a physicalfitnessprogram.

pro和con在本句中作形容词用，pro的意思是for（赞成），con的意思是against（反对）。pro or con在句子中作后置定语，修饰名词feeling。后置定语在英语中也很常见。如：

1) Countries, big or small, should be equal.（国家无论大小都是平等的。）

2) He studied in a room, clean and tidy.（他在干净整齐的房间里学习。）

（在上述例句中，两个成对的或反对的形容词，用and或or连接，共同修饰一个名词。这是形容词作后置定语的一种用法。）

1）The active involvement of thousands of people in the electioncampaign surprised him.

(成千上万的人积极参与竞选活动令他惊奇。)

2） He avoids involvement in politics.（他避免卷入政治。）

6. Certainly some of there individuals may have physicallimitations that make activity extremely difficult, and others are engaged in time-consuming activities that until finished do not permit opportunities for recreation.

that make activity extremely difficult是一个定语从句，修饰physicallimitations.

Be engaged in sth. 意思是be involved in sth.（使从事，使忙于），如：

1）They were engaged in the study of soil conservation.（他们在从事土壤保持的研究。）

2） It is inappropriate for him to engage in this activity.（他从事这一活动是不合适的。）

7.…I'll have no difficulty staying that way.

have (no) difficulty doing sth.（做某事有/无困难），也可以用have (no) trouble doing sth.。如：

1)He has no difficulty understanding the Chinese film.（看懂那部中国电影他没有困难。）

2）I had a lot of trouble getting back to sleep after I answered the phone call.（接过电话后，我无法再入睡。）

8.…you may have made a commitment to a physicalfitnessprogram that might be rather narrow in scope.

make (a) commitment to 意思是make a firm promise（作出承诺），或者involvement（投入）。

Narrow in scope意思是范围很窄，很狭隘。我们接触过在形容词后面加介词in再加名词的机构，如similar in appearance（外表相像）。

9.What could I achieve if I were really in top physical condition?

本句中用了虚拟语气，从句中用过去时（be动词用were），主句中用could或should / would / might加动词原形，表示的是与现在事实相反的假设，如：

1）If he were on time, we wouldn't have to wait for him.（如果他能准时，我们就不用等他了。）

2） If they had time now, they would come to see us.（如果他们现在有时间，他们就来看我们了。）

in top physical condition 意思是"身体很健康"。如：

The old man is in top (very good, excellent…) physical condition though he is already 76.

（老人虽已七十六岁，但身体非常健康。）

10. In the final analysis, we think that although fitness will not guarantee that you will live longer, it can help you enjoy the years you do live.

in the final analysis意思是ultimately（归根结底），如：

They realized in the final / last analysis that their job was to tell public the facts.

（他们认识到他们的工作归根结底是把事实公诸于众。）

guarantee的意思是保证，担保，后面可跟名词；to do或that从句。如：

1) Wealth doesn't guarantee happiness.（财富不能保证快乐。）

2）They guaranteed to finish the work in two hours.（他们保证在两个小时内完成这项工作。）

3）I guarantee that they will win the game.（我保证他们会赢这场比赛）。
