I’d like to tell you about my dream classroom in the future．My classroom will be very  31  ，so we can do lots of activities in the classroom．In summer，it will be  32  and in winter it will be warm，so it will be  33  ．There will be a beautiful garden in front of it．We can see many trees and  34 in it．There will be a cable TV in our classroom and we can  35  it at noon．Everyone will have a  36  on the desk，so we can read information  37  the Internet．The lessons will be interesting．We  38  use pens or pencils．We will use computers to do our homework．The teachers won’t use  39  to write on the blackboard．They will  40  the lessons with the help of the computer．

DNA is the whole “map” of the human body. It is something that all humans have, and it tells the body what to do. DNA is the reason that we look like our parents, because we get some of their DNA to make our own.

People have been trying to understand the human body for a long time. In 1860, Mr. Mendel discovered why we look the same as other people in our family. It is because of small things called “genes”（基因）in our body. In 1953, two scientists, Watson and Crick, found out that genes are really messages. They’re written in the DNA with a special language.

In 1961, another two scientists found the first “word” that they could understand in that language. It shows how DNA tells the cell (细胞）to build its parts. So far, scientists have found all the words in the DNA map, but we still don’t understand what they all do. By understanding what just one “word” means, we can help to save people from several illnesses. So the more we understand, the more doctors will be able to do.

Most people hope that this will help to make better medicine and help sick people. Other people worry that when we learn more “words” and find out more information, we will use it in the wrong way. Just to make people more attractive (有吸引力的), or stop sick people getting jobs.

A week ago, Columbus Middle School asked the parents of their school to choose a sport for their child to play. Here’s some information about the sports.

Sports 1: Basketball

We expect that this will be the most popular of the four sports. So students should sign up (报名) as soon as possible. Students will take a private bus to and from Kwun Tong Sports Park. Each student will have to pay $ 10 each time for the cost of the bus. There will be four basketball courts available for our use with one teacher watching over each game.

Sports 2: Gym

We will use St. Peter’s Park. There are two reasons for choosing this park. First, it is not very busy and crowded before 6:00 p.m. Second, it has lots of trees with plenty of shade. Students must bring along two bottles of water to prevent from being thirsty. All the activities here are free. And there will be a teacher on duty for each activity.

Sports 3: Hiking

Hiking (远足)will be at Kowloon Peak. The activity will start at 2:30 p.m. and finish 90 minutes later. There will be 15 students in each group. And three teachers will be with the students. This sport will cost $ 75 per hour. Students should take plenty of water and sunglasses.

Sports 4: Swimming

The Kowloon City Swimming Centre is a 10-minute walk from our school. Four teachers will go to the pool and watch the students from the poolside. We will only be able to use the pool for one hour (2: 45 p.m. to 3:45 p.m.). Only students skillful at swimming can take up this activity. The pool will have two lifeguards on watch. Girls must wear swimming suits. The cost is $ 15 per visit.

1.The students of Columbus Middle School should __________.

2.According to this passage, __________ will probably have the most students.

3.One of the reasons for choosing St. Peter’s Park is that__________.

4.A student need to pay __________ if he goes swimming three times a week..

5.From the passage, we know that __________.
