     On the fourth Thursday in November, Americans celebrate the  festival of Thanksgiving. This

festival is a time when the family come together for a meal and give thanks to God for the blessings

they have received. The first Thanksgiving festival was celebrated by the early American settlers who

gave thanks to God for their good harvest.

       In America Thanksgiving is a family holiday. It is on that holiday that all the family make a special

effort to get together. The feast (节日 ) is always on Thursday and most people have a four-day holiday

from school and work. Thus they are able to travel a great distance to be with their family.

     The Thanksgiving meal is traditionally turkey, which was the food for the first Thanksgiving. The table

is filled with fruits, walnuts (胡桃)  and many kinds of vegetables. For dessert (甜点) the main choice is

usually pumpkin pie. The meal is a time for the members of the family to talk to each other. There will be

talking before the meal, during the meal and long after the meal.

     On Thanksgiving morning there are sporting events and parades (游行)  in many cities to mark the

day.  The family dinner is usually held in the afternoon around 4 o'clock. The mother will prepare the

meal and the father will carve (切) the turkey. He will preside (主持)  at the head of the table. The meal

will begin with a short prayer of thanksgiving to God for the blessings the family received. The father will

also thank the family for coming together on this day. During the meal there is plenty of food for everyone

present. The meal is a very joyful time. When the meal is over, some will help with the dishes and others

will return to the living room to talk or watch television.

       In many ways the festival of Thanksgiving is similar to the Chinese festival of Mid-Autumn Day.  It is

a time for the family to get together for dinner.

最近，天文学家在距地球至少110亿光年的宇宙深处发现，众多的新星正在早期星系内快速生成。若进一步的研究能够核实那些星系的实际年龄的话，则这一新研究的成果将意味着星系诞生的高峰期远较人们以前确认的年代为早，星系生成的速度也大大高于从前的估算，宇宙早期的演化史可能需要科学家们去重新认识。

确定大量星系生成的年代对于加深了解宇宙的起源和演化具有十分重要的意义，而科学家们也一直在宇宙深处不断搜寻亿万恒星的孕育之处。然而，由于形成恒星的区域常常笼罩有浓重的星际尘埃，掩蔽了新星发射的可见光及红外辐射，而距离更远的恒星和星系所发出的辐射传到地面时已属于信号极其微弱的亚毫米波段，探测难度相当巨大。

科学家们报告说，他们探测到了与哈勃太空望远镜照片上5个古老昏暗的星系相对应的亚毫米波辐射源，并根据辐射波的强弱特点判断，这些早期的星系可能正在以高于银河系100倍的速度缔造新的恒星。

目前，天文学界普遍认为，星系大部分形成于宇宙诞生后的80亿～100亿年间，但新的发现却清楚地显示，星系可能早在宇宙处于20亿年的早期阶段就已经大量涌现了。

天体物理学家佩蒂尼评论说，新的发现是非常令人振奋的科学进展，有助于解答宇宙是如何从热大爆炸后的初期平稳阶段演变为今日所见的浩繁星系的。

根据文意，对“新的发现”的理解正确的一项是（）。

A．发现星系大量涌现的时期是宇宙处于20亿年的早期阶段。

B．认为星系诞生的高峰期远远早于目前天文学界所公认的年代。

C．对早期星系实际年龄的核实。

D．探测到宇宙早期星系内正快速生成大量新星。
