【答案】

【1】D

【2】C

【解析】

【1】“好奇号”是火星探测器,始终在太阳系内部,没有穿越,通过时间计算,西五区与北京东八区相差13时,根据东加西减的方法,伦敦在北京西边,晚8个小时,时间是26日10时。

【2】火星与地球相似主要表现为火星、地球自转周期的长度都比较适中,火星、地球与太阳的距离都比较适中,地球是目前发现的唯一有生命的天体,火星上不具备地球上适宜生命存在的条件。

How to prepare for exam?

Here are some tips you can read with your child.

The first step in preparing for examination is to set a fixed time each day to study and a schedule to say when to start the revision and for which subject. The plan should include how many chapters to revise and how many worksheets to work on. 1 . Parents who do not know the examination time schedule can search 'exam timetable' to see the official examination schedule.

2 .

The second thing is to decide on the place to study. Some need total silence in a library before they can concentrate while others like to have some background music like in the cafeteria. 3 . So there is no need to tell your child to change the study place if he is producing the desired results.

4 . For lessons, pupils must participate in lessons and discussions actively. For exercise, work on the simple ones in the textbook. For theory, pupils can use the mind map method to summarize the facts.

At last, study smart. Focus on chapters that are the core of the subject or difficult chapters. 5 .

A. Next the most effective way to revise is to use an active approach.

B. Making good preparations counts.

C. Mind map can help you a lot in your revision work.

D. Your child has to be self-disciplined to follow the plan.

E. It is not necessary to simply read from first to last page.

F. The best time to start revision is one or two months before the examination.

G. Both are alright as long as your child is comfortable with it.
