1. 英語中兩個句子用逗號連接
71題，語法上說只有A和B是對的。當時A的邏輯不對，圣路易斯現在是第24大城市而不是第四大城市，所以只有B對，一句話沒說完，逗號肯定是可以連接兩個句子的。因為如果前面句子是句號的話，大家就不知道IT代表什麼了，必須逗號才知道IT就是圣路易斯。
72題沒有兩個謂語，the building project 是主語，而后面的的謂語是并列謂語，就是說如果建筑工程在月底完工和延遲了，建筑公司就會罰款。
如果在month 和is之間加個and 就清楚。
另外從語法和意思上說，A,C,D三個選擇都是一樣的。選A就能選CD，所以排除法來看只能選B.邏輯上看B比較合適
2. 英語中兩個句子之間什麼時候用逗號隔開,什麼時候用分號呢
除了兩位親講的， 再補充其他知識：
當你看見有but, and, also, as well as, because, so 等等的字眼時. 例句：
I didn't wake up on time this morning so I was late for school. （逗號在 so 前面是可有可無， 一般不會寫因為第二個句子自己不能獨立， 不能算完整所以可有可無， 只是為原本的句子做注解而已）
當兩個句子都是獨立時， 逗號就一定得在but, and, also, as well as, because, so
等等詞后面用上， 如：
I didn't wake up on time this morning.
I had a very bad headache. 兩句都是獨立句. 加在一起時， 逗號必須出現：
I didn't wake up on time this morning, because I had a very bad headache.
如果是用however, therefore, thus, on the other hand諸如此類的， 其實是要用 ； <<；分號
例句： I didn't wake up on time this morning; therefore, I was late for school.
2. I didn't wake up on time this morning; however, I didn't have to anyway as it is a public holiday.
逗號與分號加在一起的的例句：
I didn't wake up on time this morning, I even ran into traffic, and my bike was broken; therefore, I was very late when I finally got here.
我不太會解釋但希望例句多少有點幫助~~~
3. 英語中兩個完整的句子然后用逗號隔開對嗎
不對。完整的句子就直接分成2句就好啦。
如果要把兩個完整的句子合并要加連詞，比如：and, but, or, so, therefore, yet, however, for, hence, as …。 之類的。
如：1) I scored 60% in the exams this year.
2) Anita scored 7% more than me this year.
比如這2個完整的句子就可以用but變成1句。
- I scored 60% in the exams but Anita scored 7% more than me this year.
4. 幫我找一些句子帶兩個或兩個以上逗號的那種英語句子,這種句子比
這是剛剛看到的。
It bore him up, flattered him and gave him more money than he had dreamed of, simply for telling people that he felt as they did, that something had to be done with all the nervous energy stored up and unexpended in the War.
