而 despite 和 in spite of 有“尽管……但是……”之意。
②用法上的区别：regardless of 后可跟 whether, what 引导的从句，而in spite of 和 despite 后不可接从句。

round forms of exercise.
is regarded
[解析] “名词（短语）+along with+名词（短语）”结构后的谓语的单复数一般与前一名词（短语）的单复数一致。主语cycling表单数概念，且与动词regard之间是被动关系，根据Nowadays和语境可知，此处应用一般现在时，故填is regarded。

&14& 宾语从句中虚拟语气的用法
句中recommend意为“建议；劝告”，后接宾语从句，从句应使用虚拟语气，即从句谓语用“should+动词原形”，should可以省略。
常见的有类似用法的动词有表示建议、要求、命令、劝告等的advise, suggest （建议）, order, require, insist （坚持主张）, command等以及它们各自相关的名词。
记忆口诀：一坚持（insist），二命令（order, command），三建议（suggest, advise, recommend），四要求（ask, require, demand, request）。
He insisted that all of us （should） be there on time by any means.他坚决要求我们大家想尽办法按时去那儿。
I suggested that he. .（should） go home at once.我建议他立刻回家。
She requested that no one （should） be told of her decision until the next meeting.她要求下次开会前不要向任何人透露她的决定。
特别注意
①insist表示“坚决要求；坚持主张”时，需使用虚拟语气；表示“坚决认为”时，不需要使用虚拟语气。
We insisted that what the boy did was wrong.我们坚决认为这个男孩做得不对。（insist表示“坚决认为”，不使用虚拟语气）
②suggest表示“建议”时，需使用虚拟语气；表示“暗示；表明”时，不需要使用虚拟语气。

1.His pale face suggests he _______ （stay） up late yesterday.
stayed
[解析] 根据语境可知，suggest在此意为“表明；暗示”，其后的宾语从句不用虚拟语气；根据yesterday可知,stay应用过去式。
2.His English teacher insisted that he ______ （hand） in his homework tomorrow morning.
hand
[解析] 句意为：他的英语老师坚持要求他明天上午交作业。此处insist意为“坚持要求”，其后的宾语从句应使用虚拟语气，从句谓语应用“should+动词原形”，should可省略。
3.The hotel management suggested that radios __________ （turn） off after 11 o'clock at night.
be turned
[解析] 根据语境可知，suggest在此意为“建议”，其后的从句要用虚拟语气，从句谓语应用“should+动词原形”，should可省略。从句主语radios与动词turn之间是被动关系，故填be turned。

【参考范文】
Eating habits are essential for our health.But some bad eating habits of teens are really serious now and need to be changed.
Some students usually skip breakfast, which makes them have difficulty in concentrating in class.So it's important to develop a regular eating habit.For some teenagers, eating too much fast food is a habit that they can't get rid of.Containing too much sugar and fat, fast food contributes to various diseases.It's advised to quit consuming fast food frequently.Besides, most teenagers eat so few vegetables and fruit that their bodies lack vitamins.Therefore, it matters that we keep a balanced diet.
In general, we must form a healthy eating habit.So it's high time to take action.
